1.0 General Description

Figure 1-1 Solid State Data Recorder

This manual is a user reference guide for the Solid State Paperless Data Recorder (Figure 1-1). The manual provides detailed instruction for installation, operation, programming, calibration and maintenance of the instrument.

The recorder is a sophisticated piece of equipment that requires some level of programming before use. The user is advised to read this manual in its entirety before proceeding with the installation and programming. Refer to Chapter 3, Getting Started for minimum configuration. Step by step instructions for a few sample applications are included in Appendixes A-D.

1.1 Recorder Description

The Solid State Data Recorder is a Paperless Recording instrument. Data is stored in either an internal floppy disk, a removable PCMCIA memory card or a Zip Drive.

All data is stored in MSDOS format and may be archived or analyzed on any IBM compatible PC running Microsoft’s Windows 3.1 or Windows 95/98 using the available Companion Software. The instrument retains all the features of a traditional Paper Chart Recorder by virtue of its large STN monochrome or TFT color Liquid Crystal Display (LCD) which presents the data in the traditional chart mode as well as in bar graph or digital numeric form.

The unit has many features and functions, which are unique and cannot be performed on traditional paper recorders such as data compression and historic data browsing. The recorder is programmed via a touch screen keypad on the display.

The recorder will measure and process up to six direct inputs, calculated, conditional, or external points for logging, trending, or data manipulation.

If direct inputs are not desired, the Data Recorder will accept up to fifteen points from a combination of calculated, conditional, or external point types.

1.1.1 Inputs

Direct input sources may come from voltage, current, dry contacts, thermocouple, or RTD sources. The voltage and current ranges accepted by the instrument include: ±150mV, 0 to ±1.25V, ±2.5V, ±12.5V and ±25V; 4 to 20mA, 0 to 20mA and 10 to 50mA current. Thermocouple inputs include J, K, T, E, R, S, B, C and N. RTD inputs accepted include 10 ohm Cu, 100 ohm Platinum, 200 ohm Platinum, 120 ohm Nickel and 1000 ohm Nickel.

CF 46 2 2/06

1.1.2 Instrument Size

The instrument is sized to fit in a DIN standard panel cutout of 5.43 inches x 5.43 inches (138mm x 138mm) and requires only 7.41 inches [188.2 mm] behind panel depth, not including power and input source cable space needed. Actual dimensions of the instrument are shown in Figure 2-1 Recorder Dimensions in Chapter 2 of this manual.

1.1.3 Menus

The instrument’s features are accessed through a series of menus. Press the MENU button displayed in the bottom right hand corner of the LCD screen. The STATUS bar along the top of the screen displays the various recorder parameters. (Refer to Section 3.1). The Command button bar contains three user programming option buttons - DISPLay, PROGram, and FUNCtion (see to Figure 1-2 below). Each menu level features easy-to-follow prompts that simplify operation.

Figure 1-2 The Command Button Bar

1.1.3.1 Display Menu

The Display Menu is accessed by pressing the Display button (DISPL) on the Command button bar.

The Recorder can be ordered the with one of three storage mediums, a standard PC compatible floppy disk drive, an industry-standard PCMCIA memory card drive, or a Zip drive. The Companion software provided with the unit

CF 46 3 2/06

supports all three media types.

1.2.1 Floppy Disk Drive

The Floppy disk drive uses PC compatible 3½-inch (89mm) floppy disks. These disks store 1.44 Megabytes of data, which translates to approximately 700,000 data samples (each sample is 16 bits). The disks are magnetic media and the drives are mechanical. This limits their use in harsh environments where vibration or temperature is a problem, but they are convenient as they are very inexpensive and can simply be plugged into any IBM compatible PC.

1.2.2 PCMCIA Memory Card

The PCMCIA card (Personal Computer Memory Card Interface Association) is a small solid state card containing Flash memory. The PCMCIA drive supports memory cards up to 200 Megabytes in size, which is approximately 100,000,000 data samples. The cards do require a special drive in your PC which is readily available, inexpensive and already standard on many laptops and desktop machines. Contact your dealer for details.

NOTE: It is recommended that a Sandisk 4-200 Meg Flash card be used.

1.2.3 Zip Drive

The Zip Drive stores 100 Megabytes of information, which is approximately 50,000,000 samples for a 100 Megabyte Disk. This Recorder does not support 250 Megabyte Zip drives.

1.3 Recorder Options

Additional functions and capabilities can be added to the Data Recorder as options and are described in the following paragraphs.

1.3.1 Digital Input and Output

This option provides three or six mechanical form C (Normally Open, Common, Normally Closed contacts), relay outputs capable of switching 250 VAC as well as three isolated digital control inputs, or three or six solid state open collector type contacts able to switch 30 Vdc at 0.5 Amps. The relay outputs can be programmed to respond to alarm events while the digital inputs can be used to trigger events such as changing recording speeds or stopping and starting recording.

1.3.2 Communications Interface

There are two communications options available:

1. An isolated RS232/RS485 interface using the Modbus protocol with the recorder acting as a slave device in a Modbus RTU or Modbus ASCII environment.

2. An 802.3 compatible Ethernet option with RJ45 four wire connection.

2.3.3 Signal Input Wiring

SIGNAL INPUT CONNECTIONS. HAZARDOUS POTENTIALS MAY EXIST ON SIGNAL INPUT TERMINALS WHICH ARE FLOATING WITH RESPECT TO CASE GROUND. THESE HAZARDOUS POTENTIALS MAY BE ON THE REAR TERMINAL PANEL OF YOUR INSTRUMENT. ANY VOLTAGE POTENTIAL AT THE SIGNAL SOURCE WILL EXIST ON THE INSTRUMENT’S RESPECTIVE SIGNAL INPUT TERMINAL. (I.E. POWER GENERATOR STATOR WINDING).

The Recorder accepts up to six direct inputs. Input connection is via plug in screw terminal connectors on the rear panel. Inputs can be mixed in any combination of thermocouple, RTD,

milliamps, millivolts, volts or contact inputs. There is a common ground lug, marked with a for connection of signal cable shields or screens. Read the following procedures before connecting inputs to the terminals.

Figure 2-6 DFR 2000 Rear Panel Connections

WARNING: Ensure The Power Is Off Before Connecting Signal Inputs To The Unit.

The plug in screw terminal connectors are of the clamping screw variety, putting even pressure on the signal wire. It is therefore not necessary to terminate the wires with lugs, however you may do so if you wish. The maximum gauge wire that can be accommodated is 14 AWG or 2.5mm

You will need a small screwdriver and a pair of wire cutters and strippers. The use of shielded twisted lead wire is recommended to minimize electromagnetically induced noise.

WARNING: All unused inputs must have all contacts commoned together.

CAUTION: Never run signal and power or control wiring together in the same conduit. This is to prevent

possible recording errors due to induced signals between lines. Route signal wires away from power wires at the rear panel.

CF 46 10 2/06

NOTE: Ground cable shields at one end only to eliminate the possibility of interference due to ground loop

currents. When grounded transducers are used, the shield should be grounded at the sensor end only.

3.0 Getting Started

The Instrument is an extremely versatile solid state data recorder. It has a liquid crystal display capable of complex graphical representation and either a floppy disk drive, Zip drive or PCMCIA Memory Card for data storage. The unit is easily programmable and the average user will probably never need to use most of the features or functions available in the recorder. This chapter will give the user a brief system overview and guide the first-time user into a simplified setup that will enable you to begin recording with the least amount of effort.

3.1 Moving About the Screen

The Recorder has an LCD Graphics Screen that also acts as a touch keypad. Areas of the screen are active as push buttons, the exact areas that are sensitive depends on what is currently displayed. The user has only to lightly touch the screen area depicting the button to activate the function. If the buzzer is turned on, the unit will provide audible feedback, as a short beep, each time a “button” press is registered. The default display is shown in Figure 3-1 below.

Figure 3-1 Recorder Screen

The screen is divided into three distinct areas, the BUTTON BAR, along the bottom of the screen (containing the time/date stamp), the STATUS LINE, across the top of the screen, and the GRAPHICS AREA between them. Under normal operating modes, when not in a menu, the BUTTON BAR area is active for “Button” pressing. The MENU button on the bottom right of the screen, will bring up the command menu button bar, see below, which allows the user to do a number of functions and select the option of programming the unit. Refer to Chapters 4 and 5 for details.

Figure 3-2 The Command Menu Button Bar

CF 46 14 2/06

The VIEW button is on the lower left side of the screen, and it enables the user to scroll through the selectable display options in the graphics area of the screen. These views might be charts, bar graphs, digital or Alarm information. Each time the “button” is pressed, the next view is presented. The Graphics display can be either a full screen of information, or the screen can be split, allowing combinations of the primary screens to be displayed. The user can also choose whether the screen is horizontally or vertically oriented.

The area along the top of the display is the Status Bar or Status Line, and it is used to display a number of user programmed functions such as the unit tag (identification) or the digital values of the various channels or alarm status. On the right hand side of the Status Line is the disk status information (disk info). This displays the current condition of the disk that is currently being used to save data. When the unit is not recording, this area shows REC OFF. When recording it displays REC↑ when recording at the fast rate or REC• when recording at the slow rate, as well as XX% used, where XX is the amount of disk space already recorded. The default display is set using the DISPL option on the Command Menu button bar. The JOG button is used to switch between channel data.

To the left of the Status Line is the position of the ACK button (not shown). This is the Alarm ACKnowledge and is only present when there is an alarm condition, at which time it blinks until the user presses it to acknowledge the alarm condition. Pressing the Acknowledge button will also reset any Output relays if this option is installed and programmed. Note that the ACK button will always be the top-most button, always rising to the surface when covered by other items such as menus. The user can thus acknowledge an alarm at any time, even while in the programming mode.

As the user moves through the menu options, more or fewer buttons will be shown. The key buttons are always displayed on the button bar along the bottom of the display. ENTER and EXIT buttons are always in the same place on the button bar allowing rapid movement through menus.

The BROWSe button is only displayed on screen views that can actually be browsed. These are the full Chart Screen and the full Alarm Status Screen. The user can choose to browse RAM (Random Access Memory) which is the screen trace data, or File, in which case a file menu will be presented so that the user can choose a file from the disk. The BROWS button also allows the user to SEARCH historic data either by TIME or VALUE, as well as COMPRESS data in time.

Pressing the BROWS button puts a freeze on real time display and allows the user to scroll back in time to browse through historical data that has effectively dropped off the screen or has been recorded previously, even on another machine. The actual Chart Screen browse buffer is dependent on the memory options installed, the number of traces being displayed and the effective chart speed. With the standard buffer, a chart speed of one inch per hour with four traces active, it is possible to browse back around 140 hours (5½ days). The user may choose to browse files on the disk rather than the current memory buffer even though the unit is currently recording. The user can then browse files that had been recorded earlier, or may even browse the file that is currently being recorded. Once the data has been recorded to disk, it is possible to use the file browser or the PC and the companion software to view data as far back as the start of recording, irrespective of how long that may be, within the constraints of disk capacity.

3.2 What the Screens Mean

The basic screen layout is shown in Figure 3-3 below. Each area is used to present different information to the user.

3.2.1 Status Line

The Status Line is used to show the Unit Tag, Point information, rear terminal Junction Temperature or Alarm information. The choice as to what is transiently displayed is set in the DISPL menu (Chapter 4.2.1) or the user can set the default display for this line in the “PROGram - Display - Powerup disp” menu (Chapter 5.4.3). At any time the user can press the JOG button to display point data on the Status line. Each time JOG is pressed the next point data will be shown. The data can be set to auto jog from the “PROGram – Display - Powerup disp - Autojog” menu (Chapter 5.4.3.2).

Figure 3-3 Basic Screen Layout

CF 46 15 2/06

The Point information is displayed on the Status line as “ Point No. Value Units” as shown below:

1 0.496 VOLTS

The Alarm information is shown on the Status line as “Point No. Value Alarm Type/Number” - where H1 is

1 0.496 HI

will show –

The Unit Tag is shown on the Status Line and may be up to 20 characters long. It is entered from the “PROGram Display - Powerup disp - Unit Tag” menu (Chapter 5.4.3.1) and displays as entered –

High Alarm #1. There are 5 possible alarms per channel, H = High, L= Low R = Rate. If more than one alarm is active they will cycle on the Status Line. If there are no alarms active the Status Line

NO ALARMS

This is a UNIT TAG

3.2.2 Disk Status

The area in the top right corner marked DISK STATUS is used to show Disk Status. The following messages may appear in this area:

OFF 15% Unit is not recording to disk. Record Mode is OFF - Disk is 15% full. REC ↑ 15% Unit is recording to Disk in HIGH speed mode - Disk is 15% full. REC• 75% Unit is recording to Disk in LOW speed mode - Disk is 75% full. FORMAT Disk is being Formatted. SAVE CFG Saving Configuration to Disk. LOAD CFG Loading Configuration from Disk. TRIG 75% Unit is waiting for an Event or Alarm to turn the Record Mode on - Disk is

75% full.

3.2.3 Button Bar

The Button Bar is the area across the bottom of the screen where the main menu buttons appear. The function of these buttons varies according to which mode the unit is in. Figure 3-3 shows the Normal mode button layout.

3.2.4 Date/Time Window

The Date /Time window sits at the bottom of the screen in the Button Bar and continuously shows the current date and time. Date is shown numerically in either American Month/Day/Year or European Day/Month/Year format. The format is selected in the “PROGram - Display - Time format” menu (Chapter 5.4.2)

3.2.5 Graphics Window

The graphics window is used to display various information in different formats. The VIEW button is used to switch between the various graphic displays, which can be Trend Charts, Bar Graphs, Digital Windows or Alarm/Event data, or combinations of these. Furthermore the graphics can tend to be horizontally or vertically oriented. The orientation is selected in the “PROGram - Chart/Pens - Direction” menu (Chapter 5.5.4)

3.2.5.1 Bar Charts

Bar graphs can be displayed on their own or as part of a split screen. Up to twelve can be displayed at a time. The user can select to display bar graphs either horizontally or vertically. The assignment of points to bar graphs is made in the “PROGram - Display - Bar assign” menu (Chapter 5.4.4). The format of the vertical bar graph is shown opposite in Figure 3-4. The very top of the bar has the actual/real time digital value of the point, in this case 0.385. Immediately below this is the Engineering Units shown as ENG UNITS. There can be a maximum of five characters. At the very bottom of the bar graph is the POINT TAG. This is a ten-character description of the point.

NOTE: Not all characters can be displayed on the bar graph.

Figure 3-4

Bar Chart

CF 46 16 2/06

Between the ENG UNITS and POINT TAG is a bar that represents the actual value as a function of the full scale value. To the right of the bar are scale values. The alarm setpoints, if any are set, are indicated on the bar by a “◄” in the text area. If any alarm is active, the bar will be blinking. The Engineering Units, Point Tag, alarm setpoints and scaling of the bar is done in the “PROGram Points” menu (Chapter 5.6)

3.2.5.2 Digital Windows

Digital Windows can be displayed on their own or as part of a split screen. Up to twelve can be displayed at a time. The assignment of points to digital windows is made in the “PROGram - Display - Digital assign” menu (Chapter 5.4.5). The format of the digital window is shown opposite in Figure 3-5. The large numbers in the center of the window are the real time point value. Above this point value is the Point Tag shown as POINT

Figure 3-5 Digital

Window

TAG. This is a ten character description of the point. Below the point value is the Engineering Units shown as ENG UNITS. There can be a maximum of five characters. The Engineering Units, Point Tag, and scaling of the digital value is done in the “PROGram - Points” menu (Section 5.6).

3.2.5.3 Alarm/Events Data Window

Figure 3-6 Alarm/Event Window

The alarm/event window is used to display alarms, events, reset power up and power down information. This data may also be recorded to disk by enabling Alarm data in the “PROGram – Disk functions - Alarm on/off” menu. (Chapter 5.7.2).

The second line of the display indicates the status of the alarm checking. If alarm checking is enabled this will indicate ‘Alarm Check On’ or it will indicate ‘Alarm Check Off’ in which case no alarms will occur.

The state of alarm checking is changed in the “FUNCtion - Alarm Check” menu (Chapter 4.2.3.7).

The format for any entry in the Alarm/Event file is – Date Time Point Status Value. The Point value is shown as Pt X, where X is the point number. The Value shown is dependent on the Event. The Event can be an Alarm, an input contact closure (event) or a reset, either automatic or manual.

For linear inputs, the alarm event description is HIGH1 or LOW2, where the number is the alarm count up to a maximum of 5. For conditional inputs, the alarm event descriptions are OPEN, CLOSE, TRUE or FALSE. The value is the actual value at the time the alarm was registered. An event message of “*” is an alarm return to normal condition, the time the point came out of alarm.

Resettable points, such as totalizers, will show the event as RESET, with the actual value at the time of reset. Some Resettable point types, such as HI PEAK will have two entries (Pt 6 above). The first entry is the date and time that the high peak occurred, with the peak value, the second entry, above it, is the actual time the reset occurred, with the value at that time. Note: Resettable points will not print unless the Reset Print option is turned on in the “PROGram - Points” menu (Section 5.6).

For external events via the digital inputs, the user can define separate messages for each of the three inputs, one for input activated (Close) and one for input deactivated (Open). These event messages can be entered, up to a maximum of ten characters, in the “PROGram - Digital I/O - Event msgs” menu (Chapter 5.9.3). This message will appear in the log as - date - time - Switch number (Sw X) – Event message. Default event messages are CLOSE and OPEN as seen in the data log example above.

3.2.5.4 Trend Window

The trend window is the one that looks like a “paper” recorder. It has traces or pens and emulates the paper chart, moving the “paper” across the screen, and is shown in the vertical mode in Figure 3-7 below. The direction of the trending can be vertical, from top to bottom, or horizontal, from right to left. The direction can be changed in the “PROGram - Chart/Pens - Direction” menu (Chapter 5.5.4). There may be as many as twelve pens on the chart at a given time. Pens are assigned to the chart in the “PROGram - Chart/Pens Pens” menu (Chapter 5.5.3).

Consider the vertical chart below, the same features are found on the horizontal chart. Along the top of the chart are the pen pointers, one for each pen that is on. These track the real time value of the points and identify the origin

CF 46 17 2/06

of the trace.

Figure 3-7 Vertical Trend Window

There are grids on the screen, both horizontal and vertical. In the above example, the vertical grid spacing is a function of the divisions on the chart scales. The horizontal grid lines indicate the scales for the chart, and if there is more than one scale set, they alternate. On the full screen trend view, the scales can be toggled through by pressing the middle of the scale (top center of the display). Each scale has its end points marked along the top of the chart with the scale value, the 0.00 and 1.00 indicating that the trace has a value of zero when it is hard to the left, and 1.00 when it is hard to the right. There is a marker on top of the pen pointers to indicate which pens reference the current scale. Thus when interpreting the data for pens 1 and 2 use a value of 0 to 1.00 full scale. When the scale changes, so will the markers on the pen pointers to indicate the pens for the next scale. Also along the top of the chart are the scale UNITS.

3.2.5.5 Transient Windows

Transient windows are those that appear momentarily. They pop up over any existing window to inform the user of a problem or of a background task being completed. They require a user response, normally pressing the “OK?” button, to acknowledge the message.

Figure 3-8 Transient Window

3.3 Browsing, Compressing and Searching Data

Once at the full trend screen (using the VIEW button), the user can choose to browse, search or compress either data from the disk, including the file currently being recorded to disk, or immediate past data which is buffered to memory (RAM). The operation of browsing is the same whether the user is browsing memory or file data. When BROWS is pressed a new button bar is presented with three buttons, FILE , RAM and EXIT as shown in Figure 3-9 below.

Figure 3-9 The Browse Source Button Bar

Select FILE to browse prerecorded files on the disk, RAM to browse Trend data from memory, or EXIT to return to the real time view.

Browsing allows the user to view historic data of the pens currently trending on the display or saved on the disk, without affecting any real time data acquisition. Alarm data can also be browsed from memory by selecting BROWS on the full view Alarm window. See section 3.3.5 for the added step required to browse from disk.

On the Trend screen, pressing BROWS brings up the Browse Source button bar. Press RAM to browse memory or FILE to browse from disk. This brings up the Browse Mode Button Bar shown below (Figure 3-10).

CF 46 18 2/06

Figure 3-10 The Browse Mode Button Bar

The FINDV and FINDT buttons initiate the SEARCH functions. FINDV is FIND by V The “→←“ and “←→” are to COMPRESS and EXPAND data respectively. BROWS enters the interactive Browse Screen and EXIT returns to the prior screen.

alue, FINDT is to FIND by Time.

3.3.1 Compressing Data

The data on the screen may be compressed up to 32 times the normal view, this enables long term trends to be seen on a single screen. Each time the “→← “ (Compress) button is pressed the data is compressed by a factor of 2, and it may require a short time for the recorder to process the data. Five presses give the maximum 32 times compression. The data may be expanded back by pressing the “←→” (Expand) button. The user can enter the interactive browse mode with any level of compression by simply pressing the BROWS button.

3.3.2 Searching Data By Time

The historic data can be searched by time, by pressing the FINDT (FIND Time) button. This will bring up a transient window showing the time to be searched. If the displayed time is correct press ENTER, if not press NO. This will bring up a series of windows to allow the required time to be entered. The Date will then be displayed. Press NO to change or ENTER to accept. The data will be searched and the sample corresponding to the required time and date will be placed under the cursor near the center of the screen. The search may take some time, especially if searching a large disk file. If no point is found the unit will display “No Point Found”. The user can then enter the interactive browse mode by pressing the BROWS button.

3.3.3 Searching Data By Value

The historic data can be searched by value, by pressing the FINDV (FIND Value) button. This will bring up the Search Value button bar shown in Figure 3-11 below.

Figure 3-11 The Search Value Button Bar

To set up the actual Value to search for, press the VALUE button. Use the numeric keypad to enter the value to search for. Note that you cannot search for an exact match, you will be looking for a value immediately greater than or less than the value you enter. Once you have entered the value you want, press the ENTER button.

Before you begin a search, you have to decide which PEN or point you are going to use as the search reference, and which direction you wish to search in.

Use the PEN button to select the pen trace to search. Each time this button is pressed, the next pen is selected. The current pen is shown in the status line at the top of the screen, together with the value of the trace under the cursor and its actual time and date stamp.

The search direction is determined by the button to the left of the PEN button. This button toggles between BACK and FWD. BACK will search BACKWARDS in time from the current cursor position (into older data), while FWD will search FORWARDS in time from the current cursor position (into newer data).

To initiate a search press either the FIND> button to find the first point GREATER than the search value, or FIND< to find the first point LESS than the current search value. Each time either of these buttons is pressed, the next point that meets the search criteria is found. Note that once a point is found, the next point to be found will be the one that is after the first point that does not meet the criteria. The search “hops” across all other values so that you are not bogged down finding useless information. Therefore if you are searching for a point on a sine wave, for example, you will find the same point on the same phase of the wave (360° apart). Otherwise you would find every point less than or greater than the search point which could be every point in the trend.

The point that meets the search criteria will be placed under the cursor near the center of the screen. The search may take some time, especially if searching a large disk file. If no point is found the unit will display “No Point Found”. The user can continue to search for other points in the same direction or change direction and search again. Once an acceptable point is found, the user can enter the interactive browse mode by first pressing the EXIT button to return to the Browse mode button bar and then pressing the BROWS button.

CF 46 19 2/06

3.3.4 Interactive Browse

The interactive browse mode enables the user to uniquely identify points on the screen by time, date and value, and move around in time. Once the Browse source has been selected, FILE or RAM, pressing the BROWS button again, immediately or after a search or compress operation, will enter the Interactive Browse mode, and the Browse Button Bar shown in Figure 3-12 below will appear.

Figure 3-12 The Browse Button Bar

The cursor appears near the center of the screen and it can be moved with the UP Arrow and Down Arrow keys in the Vertical mode or with the Left Arrow and Right Arrow keys in the Horizontal mode. Pressing these keys a single time, moves the cursor one sample at a time, holding these keys will cause the cursor to move in 10 sample increments. As the cursor moves, the time and date information is updated in the status window at the top of the screen. To move about more speedily, the PAGE- and PAGE+ buttons move the data forward or backward an entire screen at a time.

When browsing graphics, the Status Bar at the top of the screen shows the Date and Time stamp and actual value for the trace data directly under the cursor. Note that if you are browsing Memory there will be an “M” in the right hand corner of this line or if browsing Files, there will be an “F” as follows:

07/27/96 17:03:06 point 1: 0.318 Volts

To see the actual pen data value press the PEN button to toggle the data through each trace if more than one trace is displayed. As the data is toggled, the traces for all pens but the selected one, disappear. Press EXIT to return to real time viewing from the RAM browser or to the directory from the FILE browser.

3.3.5 File Browsing

File Browsing can be done at any time, note however that if you are browsing from disk while recording, there may be delays in retrieving data from the disk as writing to disk has priority over reading from disk. Press BROWS to bring up the Browse Select Button Bar and choose FILE, to browse files from the disk.

Note: Ensure that a disk is present and that it has suitable files or you will get an error message.

Once FILE has been pressed the unit will check the disk then bring up a directory. If there is more than one file per point, the files for that point will be displayed one under the other with an “<” indicating the current file selected as shown below. The list will scroll if it is longer than what will fit on the screen.

File Directory

P o i n t N o : 1

B AT C H 1 . D T 1 < B AT C H 2 . D T 1 B AT C H 3 . D T 1

If only one file is available per point, the directory selection will default to that file, if no files are available for that point, the directory will indicate “No Files Found”. Use the POINT button to select the point you want.

Once you have the directory listing of files for the specific point, use the ↑ (UP Arrow) and ↓ (Down Arrow) keys to select the file you wish to browse, indicated by the “<” mark. Press the ENTER button to browse the selected file. Once the file is loaded, it is browsed, compressed or searched in the same manner as the memory browser described above. Press EXIT to select a different file or EXIT again to return to real time viewing.

3.4 Getting to the Points

The Instrument is a 15 point recorder of which up to 6 channels may be direct or real world inputs. These are typically voltages or currents. Any channel not being used to record or display live inputs may be used as a computational channel. Inputs can be conditioned or scaled to display any range of engineering units. Refer to

CF 46 20 2/06

Figure 3-13 below.

Figure 3-13 Data Flow

There are four distinct levels of data handling, namely conversion, conditioning, scaling and display/record. Conversion applies only to live inputs and is the process of converting real world analog signals into a 16-bit digital value that can be used by the Recorder. There are five full-scale ranges for all conversions, 150 milliVolts, 1.25 V,

2.5 V, 12.5 V or 25 V, and DC. The converted values pass to a conditioning block which converts the binary value which is effectively a percentage of full scale, into a value useful to the user. Conditioning includes converting the binary value into a representative voltage, conditioning and linearizing this voltage to represent for example, a real world temperature as might be input by a thermocouple or RTD, and applying any other computation as required. The conditioning block handles 15 channels. The outputs from the conditioning block are referred to as base points and may be fed back to the inputs of the conditioning block to form the basis (base point) for other base point computations. This includes tracking peak or valley values, doing moving averages, timed averages, difference, totalization or any other user-entered equation.

The input to any channel in the conditioning block can be any one of the base points, or it can be the live inputs. Live inputs can have input and output scaling applied in the conditioning block unless this is pre-defined by the nature of the input, i.e., thermocouples. An example of input/output scaling is given in section 3.5.

The outputs of the conditioning block are also the values represented in the Digital Windows and are real-world engineering values. The outputs of the conditioning block are also fed through to a scale block where a chart scale is applied to each point. The chart scales determine what part of the full scale range will be used by the display/record block. There are two sets of 8 scales available to the user. The second set is an alternate set which can be applied to the base points in place of the normal set when triggered by an external event. Each chart scale may be applied to any one or more of the base points to provide an output scaled point. These scale points are then applied to the display/record block which consists of the visual information or recorded information that the user requires. Up to twelve scaled points are applied to the bar graph display. Up to twelve may be displayed on the chart and up to fifteen may be recorded to disk. Note that points recorded to disk need not be the same as points displayed on the bar graph or the chart, however, in the case of the chart, any point which is not recorded to

CF 46 21 2/06

disk will have limited browse capability. The user should also be aware that applying scaling other than full scale output to recorded data limits the data to the range between scale endpoints. It is possible to store the base point with different scaling than is used to display it on the chart using one of the computational channels.

3.5 Using Chart Scales

To better understand the use of input and output scaling, and how scaling base points affects the data, consider the following example, highlighted by Figure 3-14.

Figure 3-14 Scaling Example

Assume the user wants to record the output from a pressure transducer that gives a 0 to 5 volt DC output signal. This coincides to a pressure of 0 to 3000 pounds per square inch (PSI). The process being monitored typically runs at 2200 PSI ±10%, this is the area of interest. The output of the transducer that peaks at 5 volts is connected to live input channel 1 and the 12.5 volt full-scale range is selected to cover this range. Since the maximum input voltage will be only 5 volts on a 12.5 volt range, use the input scale option to set the low end at 0.0, and the high end at

5.000 volts. To convert this directly to PSI, the output scale is set at low point 0.0 and high point 3000.0. The base point now becomes 0 to 3000 for an input of 0 to 5 volts, scaled linearly across the range. The engineering units can be set to PSI and the point tag can be set to any label that identifies the process. All of this is accomplished in the Points menu - Section 5.6. Apply scale A to the base point, this too is selected in the Points menu.

It is then necessary to define chart scale A to suit the requirement - Section 5.5.2. In order to maximize the display resolution, the user is interested in pressure ranges from 2000 to 2500 only. Scale A is thus set for a low end of 2000, a mid-range of 2250 and a high end of 2500. This scale point is now assigned to the bar graph and the chart graph. The chart will thus display from 2000 to 2500 as will the bars, maximizing the display resolution for the value of interest. The user can choose to record this particular value, in other words, what you see on the chart is what is recorded to disk, values from 2000 to 2500. Or, if so desired, the user can choose to record a second point that will show pressures from 0 to 3000. To do this, use the channel 1 as a base point for a computational channel and multiply this value by 1 which is then recorded to disk.

3.6 Programming

While the unit may be programmed remotely, this exercise deals with manually programming the unit from the front panel using the display and the touch screen keypad. Various buttons and keys will be presented on the display. The user simply makes a choice by pressing the appropriate key or button. In some instances, direct selection is not possible but rather a series of choices is made by using an UP or DOWN arrow button, pressing ENTER or EXIT. Once programming is complete, the unit automatically LEARNS the current setup, which is stored in nonvolatile memory and remembered indefinitely.

When powering up the unit for the first time or if the data in the nonvolatile memory should become corrupt, the user will be asked to perform a Smart Initialize, select No. The user will then be requested to perform a full initialization. Select Yes at this stage to reset all values to the default.

There are many parameters that can be programmed, including time and date, the display, the virtual chart and pens, the points, the recording capability, the alarms, the digital outputs and the communication port.

CF 46 22 2/06

3.7 Programming Time and Date

Begin by programming the time and date. To enter the program mode, press the MENU button displayed in the bottom right corner of the screen. This will bring up the Command Button Bar. The Status Line may display “Command?” or any other preprogrammed item that the user has chosen. To enter the Programming mode, push the PROG button, which will bring up the Program menu. The user can navigate about this menu by using the UP and DOWN arrow keys to highlight the menu choice and then pressing ENTER. Note that as a choice scrolls off the bottom of the menu, it reappears at the top. This is a quick way of getting around the choices. Some buttons also auto repeat. At any time, the user can exit from the menu by pushing the EXIT button as many times as it takes to return back to the display screen.

Use the UP and DOWN arrows to select the Time and Date menu choice then press ENTER. The current time will be displayed in 24 hour format. If the time is correct, you may choose not to program the time by pressing YES or ENTER to accept the current time. To change the time, press NO. You will be presented with the hours menu and a numeric keypad which will enable you to enter the current time in hours. Use the LEFT and RIGHT buttons to move the cursor to the digit you wish to change or simply enter the hours using the numeric keys. Use the SPACE button (SPC) to clear any digit. Once you have selected the correct number of hours, press ENTER. Note that you cannot enter an illegal value. Once the hour has been programmed, the minutes menu will be presented. This will then be followed by the seconds menu once the minutes have been programmed.

Once the time has been programmed, the date is presented. To change the date, select No. To accept the date, select Yes or ENTER. Once the date has been programmed or accepted, you will be returned to the Program menu.

3.8 Programming Points

The points are the input or calculated channels that are assigned to the display or are recorded. In case there is any incorrect point data stored, clear all points before reassigning them. To do this, get to the Hidden menu (Press MENU then the upper right-hand button (disk status area)). Select Initialize then press ENTER and then using the UP and DOWN arrow keys select the Clear Points menu option by once again pressing ENTER. You will then be asked whether or not you wish to “clear?” the points. Select Yes, which will return you to the menu. Press EXIT twice to return to the Programming menu.

From the Program menu, select Points and press ENTER. You will be given the option to either program points (Prog point) or program constants. Select Prog(ram) Point and press ENTER. You will be presented with an alphanumeric keypad and will be prompted for which of the twelve possible points to program. Select 1 and press ENTER. The Points Program menu will be presented. You can choose to either set up a point “Setup pt”, copy the data from another point that has already been set up “Copy pt”, or restore the original data you just removed “Restore Pt”. Select “Setup pt” and press ENTER. You now have a selection of various ways in which this point can be programmed. These include Linear, Industrial square root “Ind sqrt”, Log linear, thermocouple “T/c”, RTD, Calculated, Conditional, or External. Program this point as a Linear point by selecting Linear from the menu and pressing ENTER. You now have to choose the full scale input range for this point. Note that when this point is programmed as a milliamp input, it is necessary to set the switch for that channel on the rear panel to connect in the terminating resistor that allows the current to be measured as a voltage input. Read chapter 5.6 for more detail. Program this point for one volt full scale input by using the UP and DOWN arrow keys to select “1.25V” and pressing ENTER. You will now be presented with a menu that enables programming of various options pertaining to this particular point in the one volt full scale mode. These include the Point tag, Input scale, Output scale, Engineering units, Alarms and Chart scale. Refer to the detailed chapters for those items not covered below.

3.8.1 Point tag

This is an alphanumeric indication of what the point represents and is generally located or displayed at the bottom of the bar graphs or on the chart itself. This information is also stored to disk to uniquely identify the point. To add a point tag, select this option and press ENTER. You will be presented with the first page of an alphanumeric keypad. There are four pages available which includes all the upper and lower case alphabet characters, numerics and various signs and symbols for programming engineering units. Up to ten characters for the point tag may be entered (only six will be displayed on the screen). To access characters on another page, simply press the PAGE button. The space is ‘SPC”, the LEFT and RIGHT arrows move the cursor to the position you wish to edit or enter. You may exit this menu choice without programming a tag or, once programmed, press ENTER to return back one

CF 46 23 2/06

menu with the tag in place.

The way data is displayed on the chart or recorded to disk is a function of three things: the input scale, the output scale and the chart scale. These may be programmed independently to provide a full scale output of any range of the input.

3.8.2 Input Scale

Select Input scale from the menu and press ENTER. You will be presented with the value to represent the low or bottom end of the input scale and for this range, it will default to 0. Up to thirteen characters can be entered. The number can be in floating point format using the E Key. It may be positive or negative, right or left justified. For our programming example, accept 0 as the low end and press ENTER. You will now be presented with the option to program the high value. This value will default at 1.25. For the sake of our exercise, accept this value by pressing ENTER.

3.8.3 Output Scale

The output scale is the value that will be reflected on the display or recorded to the units and will once again be scaled by using the chart scale programmed at a later time. Select Output Scale by pressing ENTER. What we will do is program this to be 0 - 100. This first option presented is to select the number of decimal places that will be presented. This varies from 0, which is a whole number, through to 5, which is E notation. Use the UP and DOWN Arrow Keys to select three decimal places and press ENTER. Once selected, you will be presented with the value for the low end of the output scale. This will default to 0, select this value. You will now be presented with the high value, which defaults to 1. Use the RIGHT Arrow Key to move the cursor under the decimal point then press 0 twice and the period or point once so that you have 100.0 on the display, then press ENTER. You have now effectively programmed the output scale to represent 100 times the input scale.

3.8.4 Engineering Units

At the program menu, use the UP or DOWN Arrow Keys to select Engineering Units and press ENTER. You may enter up to five characters representing the Engineering Units using the alpha numeric keypad in the page mode as done for the point tag. We will use percent as the Engineering Units. Press the Page button three times until you see the ‘%’ (percent) sign. Press the ‘%’ (percent) button and press ENTER. We have now programmed the Engineering Units to percent.

3.8.5 Chart Scale

To finalize the display scaling, we need to set the chart scale. Select this option from the Program menu Chart/Scales - Scales, and you will be offered a choice, Chart Scale = A by default. You can select one of eight scales numbered A - H by using the UP or DOWN Arrow Keys. For the sake of this example, select B as the chart scale to use and press ENTER. You will be returned to the Programming menu. The actual chart scale is programmed elsewhere and is covered in Section 3.9.1.

3.8.6 Alarms

There are five alarms associated with each point and these can be programmed using the Alarm menu. Select Alarms and press ENTER. At this point in time, we are not going to spend any time on programming the alarms. You may browse through it to see the capability of the instrument. Programming alarms is dealt with in Section

5.6.5.10. Note that in order for Alarms to be active, the user has to enable Alarm checking in the FUNCtion Menu. Press Exit to return to the Programming menu then press Exit one more time to exit the Programming menu. You will be asked whether or not you wish to keep Setup. Answer yes at this point in time to load the values into the system.

3.9 Programming Point Scales

See also Section 5.5.2. From the Programming Menu use the UP or DOWN Arrow Keys to select the Chart Pens programming option.

3.9.1 Programming Scales

Select the Scales option. Here you can program to Chart scales. Two sets of eight scales are available -Set ‘1’ labeled A - H and set ‘2’ labeled A - H. The exact details are covered in Section 5.5.2. Right now we wish to program the scale that we assigned to the previous Point 1 we have just programmed. Use the arrows to select the

CF 46 24 2/06

scale 1B then press ENTER. You are now presented with a menu which enables you to program the scales. The scale type can be programmed logarithmic or linear and defaults to linear which we will accept.

3.9.1.1 Scale Ends

Use the arrow keys to select Scale Ends and press ENTER. You are presented with a menu to select the number of decimal places that will be presented, 0 - 5. Use the arrows to select two places and press ENTER. We will assume that we wish to present the percentage scale from 40 to 80 percent only across the screen effectively expanding the resolution that we can see. Enter a low value of ‘40’ and press ENTER. You will then be asked for a mid-scale value. The scale can be made non-linear by entering a mid-point that in fact is not midway between the two end points. The advantage of this is described in the Using Scaling Section at the end of this chapter. Keep things linear by selecting the mid-point as being 60 which is halfway between the 40 and 80 end points we chose to select. Use the RIGHT (→) Arrow Keys to position the cursor under the ‘5’, which is default, and press ‘6’. The display should read ‘60.00’. Press ENTER to accept. For the high value, enter 80. Press the space twice, enter ‘8’ so that the display shows ‘80.00’ and press ENTER. You will be returned to the Scale Programming menu. Programming of other options such as scale type, scale ends, scale grid and scale units is covered in Section 5.5.2.

3.9.1.2 Scale Units

The Scale Units can be programmed in percent to match the output scale programmed in Section 3.8.3. Once this is done, press Exit twice to return to the Main Programming menu. We have just programmed Point 1 to be a live input of 0 - 1 volts which will be scaled to an output of 0 - 100% and we have chosen to display between 40 and 80% full scale on the display and this is what will be recorded to disk. The user can now program the other points in a similar fashion, simply selecting the point number and choose to copy point 1 into points 2 and 3 or program these from scratch. It is suggested that the user fully reads the rest of the chapters of this manual to become familiar with the functions of the various menu options.

3.10 Recording Data

The recorder saves data, on command, to either 3½ inch floppy disk, PCMCIA memory card or a Zip disk depending on which option you have. The disks are MSDOS™ compatible and can be read on any IBM PC compatible with a 3½ inch floppy drive, PCMCIA or Zip drive. Data is stored on the disks as individual pen files with additional files for configuration and alarm/event logging. Any DOS or Windows file manager can be used to move, rename, erase or archive the files. Recording may be started or stopped manually, by an external event or on internal alarm.

Each of the 15 points may be recorded at different sample rates, or the user can choose to record all points at the same rate. This enables slowly changing parameters to be recorded at a slower rate than faster changing signals. Also the user can choose whether to store data in average or instantaneous modes.

The amount of data that can be saved depends on the number of channels and the sampling rate; both parameters can be set by the user. As a guide, a typical 3½ inch 1.44 Megabyte floppy disk can hold approximately 700,000 16-bit samples, a PCMCIA Flash card can hold approximately 10,000,000 samples for a 20 Megabyte card, and a Zip Disk holds approximately 50,000,000 samples for a 100 Megabyte Disk.

These numbers must be divided by the number of channels and the sampling rate to determine the total storage time for the disk. For example, using a 3½ inch 1.44 Megabyte floppy disk, recording four channels at 1 sample per second, the total recording time is:

700,000 divided by 4 (channels) multiplied by 1 (second) = 175,000 seconds or 48 hours.

If the sampling rate were changed to 60 seconds, or 1 sample per channel every 1 minute, the recording time becomes 120 days.

There is an option that allows the recorder to recycle data on the disk. The user can also store other types of data on the disk. Configuration files contain information about how the recorder is set up and uses the space of around 4,000 samples. Alarm/Event log files record all alarm and/or events to disk. Each Alarm or event uses the space of 6 samples.

CF 46 25 2/06

The amount of data that can be stored on a disk is thus a variable dependent on circumstances (how many alarms occur) and what has been selected for recording. We will use the recorder to format a disk and set it up to record four channels at a sample rate of once every five seconds.

NOTE: Before a disk can be used for recording it must be FORMATTED. For best results, format the disk inside the Recorder.

3.10.1 Using the Recorder to format a floppy/zip disk or PCMCIA card

With the unit turned on, locate the disk drive behind the pull-down panel below the LCD screen. Ensure the disk is not write protected. The plastic slide in one corner of the floppy disk must be in a position such that it exposes the hole in the plastic cover. The PCMCIA card may have a tiny slide switch on the back end which will be marked as to which way is write protected. Insert the disk, label side up, into the drive and push home. In the case of the floppy or zip disk, the metal slide goes into the drive first.

Press MENU at the bottom right corner of the LCD screen. This will bring up the command button bar. Press PROGram and use the UP and DOWN Arrow keys to scroll the highlight bar to “Record Setup” then press ENTER. This will bring up the Record Setup Program Menu. Use the UP and DOWN Arrow keys to scroll the highlight bar to “Format”. This will bring up a window that displays “Format = NO*”. Press YES then ENTER to begin formatting. The light on the drive will come on until the format is complete and a “Format Done” message will be displayed. Press “OK?” to end the format. The disk is now formatted and ready for use.

3.10.2 Selecting the Record Mode

There are a number of parameters that need to be set up before actual recording can take place. These are - which channels or points to record, at what rate to record them and which record fill mode to use. There are basically two record fill modes - “Fill to end” and “Cyclic.”

3.10.2.1 Fill to End

Data is recorded on the disk until the disk is full, then the recording stops. The status of the disk (amount of disk space used in %) is displayed on the status line.

3.10.2.2 Cyclic

Data is stored on the disk in blocks. In the cyclic mode, once the disk becomes full, the first block of data recorded is overwritten by the most current block. A block contains approximately 500 samples, thus the 500 oldest samples are replaced with 500 newest samples. This continues to happen until the recording is stopped. The recorder recycles the space on the disk and can record indefinitely. The oldest data is always replaced with newest data and you will have a record of the most current data. The amount of data that will be on the disk is calculated as described above.

3.10.2.3 Average or Instantaneous Recording

There are two methods of storing data to the disk, average or instantaneous. Average mode will average all input data sampled at 4 times per second to the record rate being recorded. Thus if data is being stored to disk once every minute (60 seconds), 240 samples will be averaged. Instantaneous mode stores only the latest sample to the disk and is used if you have one of the special functions enabled, such as peak reading or moving average that does not need to be averaged.

CF 46 26 2/06

3.10.3 Programming the unit for recording

To program the unit for recording, press MENU in the bottom right corner of the screen then press PROGram. Use the UP and DOWN Arrow keys to highlight the “Record Setup” menu option. Press ENTER to go to the Record Setup Programming menu as shown opposite in Figure 3-15.

3.10.3.1 Set the record mode

Use the UP or DOWN Arrow keys to highlight “Record Mode” and press ENTER. Then use the UP or DOWN Arrow keys to select “Fill Mode”. Use the UP or DOWN Arrow keys to select either “Fill to End” or “Cyclic” and press ENTER. This will set the record mode and return to the Record Setup Menu. To select Instantaneous or Average record mode, select “Inst/Avg All” to set all channels at once to the required mode, (as opposed to Inst/Avg Indiv” to set each channel individually.) Use the UP or DOWN Arrow keys to select Average and press Enter to select then press EXIT to return to the Record Setup menu.

3.10.3.2 Points

Now you need to decide which points you wish to record. Use the UP or DOWN Arrow keys to highlight “Points” and press ENTER. A window pops up and displays “Point 1 = NO*” or “Point 1 = YES*”. To record this point press YES, to exclude this point press NO, then press ENTER to move to the next point. There are fifteen possible points, 1 - 9, A, B C, D, E and F. Set points 1,2,3 and 4 to YES. Exit this menu at any time by pressing EXIT, or accept any entry by pressing ENTER.

3.10.3.3 Record Rate

The record rate is the rate at which data is recorded to disk. It may be set independently for each channel, or for all channels together, from a fastest time of eight times per second by setting the record rate to 0 seconds, or the slowest rate of once every 600 seconds (ten minutes).

To set the Sample Rate, use the UP or DOWN Arrow keys to highlight “Sample Rate”. This brings up the Sample Rate menu. Use the UP or DOWN Arrow keys to highlight “All rates”, ignoring Autorate and Individual Rates for now. The display will show “secs (lo) >1 <” for seconds low. Use the numeric keypad to enter the sample rate 5 (5 seconds between samples, 0=8 samples/sec) and press ENTER. This sets the record rate for all channels simultaneously. The display will then show “secs (hi)>0 <”. Use the numeric keypad to enter the record rate 5 and press ENTER. Note for this purpose, both high and low record rates are set the same. The record rate can be changed by an external event if the digital I/O option is fitted or by an alarm event.

You need to arm the unit to record the actual data using the “Data on/off” menu selection. Use the UP or DOWN Arrow keys to highlight “Data on/off” and press ENTER. The current record status will be shown as “Record Data =Yes” or “Recorder Data =No”. Press YES then ENTER to enable recording of data or NO then ENTER to inhibit data recording. There is also an option to enable ALARM or EVENT recording using the “Alarm on/off” menu option. To actually begin recording you must exit until you get the command button bar. Press the FUNCtion button and use the UP or DOWN Arrow keys to highlight Record On/Off and then press ENTER. There are three choices

- “Record Off” will stop recording, “Record On” will start recording and “Trigger” enables automatic stop and start recording based on internal or external events that have been initiated. Ensure there is a formatted disk in the drive then select “Record On”. From the pop-up window press YES then ENTER to begin recording. Once a recording is started the drive light comes on periodically as data is stored to the disk. Also, the status line at the top right of the screen will indicate the percentage of the disk used.

WARNING: Never remove a disk from the drive while the drive light is on.

To stop the recording, return to the same menu and select “Record Off”. From the pop-up window showing “record off?” press YES then ENTER. Wait for the disk light to go out and the status to show REC OFF before removing the disk.

Figure 3-15

CF 46 27 2/06

3.11 Hot-Swap

Hot-Swap is the ability to “Swap” disks without turning off the record mode so there is no data loss. WARNING – DO NOT REMOVE THE DISK WHITE THE GREEN LIGHT IS ON. When the disk is pulled out, a window will appear (see Figure 3-16) displaying the time left before data is lost. For the fastest record rate 4 times per second, you wil have approximately 5 minutes (see chart below). Each pen has its own buffer so the approximate times listed are for any number of pens.

The time in the window will count down in two second intervals for sample rates faster than 2 samples per second. The window will count down in intervals equivalent to the sample rate for rates faster than 2 samples per second.

If the disk is not replaced within the time frame displayed, data will be lost.

If there are different record rates, the buffer time displayed will be for the fastest record rate.

Figure 3-16 Buffer Time

Window

3.12 Changing File Names

The user can name files to help identify the process being measured. The system uses a single filename for all types of files, pens, alarm, and configuration. The filename can be any DOS compatible name. To change the filename, select Record Setup from the PROGRAM menu and press Enter. Use the UP (•) or DOWN (•) Arrow keys to highlight “Filename” and press ENTER. The current filename will be displayed. Use the alphanumeric keypad to enter up to eight characters. Do not enter any file extension or “.”. Press the ENTER button when done. Filenames can be changed as often as needed and multiple file sets can be recorded onto the same disk. Multiple configuration files may also reside on a single disk.

3.13 Setting the Disk Full Alarm

It is possible to set a threshold to indicate when the disk is full. The indication is via a pop-up window on the screen, or if the relay option is fitted, via a contact closure. The threshold limit may be set by the user to any value between 1 and 100 percent.

To set the disk full alarm value, press the MENU button and then select the PROGRAM button. Use the • (up arrow) and • (down arrow) buttons to select the “Record Setup” option and press the ENTER button. This brings up the Record Setup menu. Use the •(up arrow) and •(down arrow) buttons to highlight the “Disk Full Alarm” option and press ENTER. There are two menu options, Setpoint and Contact #. Select “Setpoint” and press ENTER. Use the alphanumeric keypad to enter the percentage point at which the disk will indicate nearly full (0 to 100 percent, where 0 implies do not indicate disk full) and press ENTER. Select “Contact #” and press ENTER. Use the numeric keypad to enter a relay contact number, 1 through 6, or 0 for no contact closure. Press ENTER to return to the Record Setup menu. A message will pop up on the display when the disk usage equals the percentage value entered above and the corresponding relay contact will close. Note that in all cases a message will pop up on the display and the relay contact will close when the disk is full.

3.14 Loading and Saving Configuration Files

Once all the points have been set up and all other data has been programmed, it is advisable to save the configuration to disk. Thus if the user needs to change any parameters for a different recording session, the prior settings can be recovered by loading a previously saved configuration file.

To save the configuration use the up arrow and down arrow buttons to select the “Record Setup” option and press the ENTER button. This brings up the Record Setup menu. Use the up arrow and down arrow buttons to highlight the “Save CFG File” (save ConFiGuration) option and press ENTER. A pop-up window will display “Save config = NO”, press YES then ENTER to save the configuration with the current filename to the disk. The disk status window will show SAVE CFG and a window will pop up when the configuration has been saved. Press OK.

To load an existing configuration select “Load CFG File” from the Record Setup menu. A pop up window will display “load config=NO”. Press the YES then ENTER buttons. The unit will look on the disk for any configuration files

CF 46 28 2/06

which will be displayed on the File Browser Directory. If more than one file exists on the disk, the directory will list them one above the other, with the current file to be loaded indicated by the “<” sign alongside it.

File Browser Directory

Config Files:

OLDFILE .CFG< NEWFILE .CFG

If more than one configuration file exists use the up arrow and down arrow) buttons to select it and press the ENTER button. This list of configuration files will scroll down if it is longer than what will fit on the display. The unit will load the selected configuration file from the disk, and a window will pop up indicated that this has been completed. Press the OK button. At this point in time the recorder has to be restated by first removing then reapplying the power, in order to recognize the new settings.

4.0 Operation

4.1 Instrument Power-up

The Recorder executes multiple tests at initial start-up. These tests are referred to as Start-up Tests. While these tests are being performed, the recorder displays “Wait” on the status line. If the system fails any test, an error message will display and an error beep will sound. Be aware, however, that certain test failures are considered non-recoverable and will result in a complete shut-down of the system. These failures require immediate repair before the Recorder can continue to power-up.

4.1.1 Start-up Tests

The following paragraphs explain each test performed at initial start-up along with any possible error messages and recommended operator actions.

4.1.1.1 Memory Test (RAM)

This routine tests all memory (RAM). If this test fails, the unit will halt, indicating the error, and must be repaired before further operation is allowed.

4.1.1.2 ROM Test

A test is performed to verify the integrity of the system software by computing a 32-bit cyclic redundancy code (CRC) and comparing this code with a code stored in EPROM. If this test fails, the operator is given a choice to accept the fault and allow power-up to continue or not accept and power down the unit. If not accepted, the unit will halt and must be repaired. The only time this fault should be accepted is after installing a software upgrade

to the instrument.

4.1.2 Load Database (user configuration)

The user configuration for the unit is stored in non-volatile battery backed memory. This memory consists of two main sections, Profile and Data Point Registers (DPR). The database is transferred from working memory areas to holding memory areas. The unit transfers this database back from the holding memory area to the working memory area during the power-up sequence. If no errors are detected, this transfer is practically instantaneous, no messages are displayed, and the recorder continues to power-up normally.

The units user Profile database is grouped into blocks. Each block contains setup parameters related to a particular instrument function (i.e. display, chart, scan, etc.) and is protected by a checksum. The DPR database is also composed of discreet blocks, each block containing all the set-up information of a particular programmed Point. Each point DPR is protected by a checksum. During the automatic Learning operation, the Profile blocks and Point DPRs along with their checksums are transferred to the holding memory area.

If the recorder finds a bad checksum in any Profile block during the power-up load database sequence, it will halt. The user is given a choice to ignore the problem or perform a Smart or Full initialization. (See Section 4.1.3 Initialize Database.)

CF 46 29 2/06

Answering NO to both “Smart” and “Full” initialization queries forces the Recorder to continue to power-up with corrupt parameters in the User Profile Database. This may be successful or the Recorder may “hang-up” or periodically reset.

Failures in the profile database should not occur. If this error occurs, a Smart initialization will have the least affect on the user profile database and allow completion of the power-up sequence.

If the Recorder finds a bad checksum in any Point DPR during the power-up load sequence, it will not issue any error message. Bad DPR’s are flagged as “CORRUPT”. A corrupt DPR may only be corrected by reviewing the associated point.

4.1.3 Initialize Database

Three forms of initialization (init) may be performed on the Unit’s Profile database, Smart Init, Full Init and Erase Configuration. The user will not typically see these options unless the unit is being powered up for the first time, or the unit finds an error in the database. These conditions may be manually invoked using the Hidden menu option.

4.1.3.1 Smart Init

Smart Initialization verifies that each Profile database block has a correct checksum and (if incorrect) each parameter in the corrupt block(s) is verified to be within allowable boundaries. Only those parameters in corrupt blocks found to be outside these boundaries are changed. Bad parameters are always replaced with pre-defined defaults.

4.1.3.2 Full Init

If the user answers no to “Smart init?”, a choice is presented to force the Recorder to do a “Full init?”. Full initialization will completely clear all user-defined parameters, setting them to pre-defined defaults.

4.1.3.3 Erase Config

This option is used on first time power up and will not normally be seen by the user unless the database has been corrupted or this option is called from the SYSTEM menu. This option will clear all variables to zero, and should be used to clear memory before programming for the first time, or after upgrading the firmware. This operation is usually performed at the factory.

4.1.3.4 Init Defaults

The listing below gives the default parameters that are used by both Smart and Full initialization: Display Block Power-up Display Mode = Unit Tag Display Rate = 1 second Time Format = American Language = English

Scan Block Alarm Contact Outputs = Open on Clear, No Reflash, Failsafe off, Open on ACK Alarm Checks = Enabled TCBO Test Interval = 300 seconds (5 minutes)

5.0 Programming

5.1 Introduction

This chapter provides information for programming the Recorder. Custom programming is required to define functions and allows you to personalize features for performing specific applications and tasks. Programming is simplified with menu-driven prompts that minimize the amount of time required for programming. The programmed information is stored in nonvolatile memory until modified by the user. The user has to program the points or data channels for scaling, display and logging or recording. Other options allow the user to program the display, alarms and event monitoring as well as overall unit operation.

NOTE: Programming will be easier with a full understanding of the programming structure. For this reason, it is recommended that you read this entire chapter before attempting to program your Recorder.

NOTE: Menu items shown on the unit display always start with a capital letter, whereas end functions always start with a lowercase letter.

Press ENTER when programming high chart speed is complete and the display returns to the “Set speeds” menu item. Press EXIT three times to return to the Main Programming Button Bar.

5.5.2 Scales

Scales are used to display and record all or part of the preselected Output Scale. The user can effectively zoom all or part of the available range. The user can also configure the grids printed on the display. Two sets of 8 scales A through H can be programmed. Only one of the two sets is active at any given time. The active set can be selected via remote switches or from the front panel using the FUNCtion programming option.

Each BAR GRAPH and/or pen is driven by a point. Any point in the system can be assigned to one or more of the pens and/or bar graphs. A scale from A through H is selected for each point during point programming. Since more than one point can be assigned to each scale, programming of the scale parameters is done separately in the Scales menu. The point assignment connects the bar graphs, pens and display grids with the corresponding scale.

To enter the SCALE menu use the UP (•) or DOWN (•) Arrow Keys to select the “Scales” and press ENTER. The display will read “scale? XX”. Use the UP (•) or DOWN (•) Arrow Keys to select the scale to program, 1A through 1H or 2A through 2H, and press ENTER.

Pressing ENTER will provide the following programming choices for the SCALE.

5.5.2.1 Scale Type

The scale type can be LINEAR or LOG. For linear scales, the point data is interpolated linearly across the defined segments. For log scales, the log 10 of the data is used in the interpolation.

Use the UP (•) or DOWN (•) Arrow Keys to select the “Scale type” and press ENTER. Use the UP (•) or DOWN (•) Arrow Keys to select the “type LIN” for LINEAR or “type Log” for LOGARITHMIC and press ENTER to select the displayed Scale type. The display will return to the “Scale type” menu item.

5.5.2.2 Scale Ends

A low, mid and high end point is programmed for each scale. The low and high end points indicate the values at the left and right margins of the chart and the bottom-most and top-most segments of the bar graph display. The mid point defines the center of the chart and need not be the halfway between the low and high values of the scale. If the point data is outside the range between the low and high end-points, the pen is positioned in one of the chart ends and the bar-graph is all-on or all-off. In the case of LOG scales, these end points are programmed in exponents with an implicit base 10 in the range 10-25 to 1025. The graph will be linear between the low and mid points, and the mid and high points and the mid point need not be midway between the low and high points. The graph can thus be made to amplify data by offsetting the midpoint for example, if the full scale is zero to 10, and low = 0, high = 10 and mid = 8, half the display will show 0 to 8 and the other half will show 8 to 10. Thus the upper half of the display represents only 20% of the chart and will have four times the resolution of the lower half of the display as shown below:

CF 46 41 2/06

Use the UP (•) or DOWN (•) Arrow Keys to select the “Scale ends” and press ENTER. The display will prompt for the number of decimal places desired, “places? X”. Use the UP (•) or DOWN (•) Arrow Keys to select the desired number of decimal places and press ENTER. The display will prompt for low scale value, “low•XXX•”. Use the numeric keypad to set the low scale value and press ENTER. The display will prompt for low scale value, “mid•XXX•”. Use the numeric keypad to set the mid scale value and press ENTER. The display will prompt for high scale value. “hi•XXX•”. Use the numeric keypad to set the high scale value and press ENTER. The display will return to the scale ends menu item.

NOTE: If the point data falls outside the programmed range of a selected scale, the information recorded will only reflect the upper or lower most value on the scale.

5.5.2.3 Scale Grid

The scales are shown on top of the chart with the major and minor divisions. The grid printed on the chart is the vertical continuation of the major divisions. For the log scales, the major and minor divisions are fixed with nine minor and one major division for each decade.

NOTE: If the number of decades between the ends and the mid point of the scale is greater than eight, the minor and major divisions are not printed. If the grids are too fine they may appear as a solid line on the display which may not be able to resolve them.

To program the grid use the UP (•) or DOWN (•) Arrow Keys to highlight “Scale grid” and press ENTER. The display will show “Major•XX•” which is the number of vertical grids that will be printed on the screen. Use the numeric keypad to enter the number of major grids and press ENTER. The display will show “Minor•XX•” which is the number of vertical stripes that will be printed between the major grids on the screen. Use the numeric keypad to enter the number of minor grids and press ENTER.

5.5.2.4 Scale Units

A five character engineering units field can be programmed for each scale, which is shown at the top of the graph (see Section 3.2.5.4).

Each of above parameters is described in the following paragraphs:

5.6.5.1 Point Tag

A Point Tag is a name used to identify the point on the display or recorded file. It may be up to ten characters long of which only eight display on the screen. The point tag appears on the bar graphs and Digital displays. To program a point tag use the UP (•) or DOWN (•) Arrow Keys to highlight “Point tag” on the above menu and press ENTER.

The display will show the existing Point Tag if any as “•POINT TAG•“. Use the Alphanumeric keypad to enter up to ten characters for desired Point Tag then press ENTER to return to the Point Setup Menu.

5.6.5.2 Input Scale

Low and high input scale is used for configuring the Recorder for the actual input provided by the transducer. If the input range full scale, e.g. 12.5V, exceeds the actual input signal, say 5V, only half the input range is actually used. By adjusting the Input scale setting to be 0 to 5V, the entire input range is used for 5V. Note that the resolution is halved. Only voltage inputs require setting low and high input range values.

NOTE: During point programming, input range voltages are programmed in the same engineering units as the voltage range selected, i.e. mV or Volts.

Programming Input Scale - Use the UP (•) or DOWN (•) Arrow Keys to highlight “Input scale”. Press ENTER and the display reads “lo•XXXXXXXXXXXXX•” (13 places possible). Use the numeric keypad to enter the

low end scale value, the default is zero. Press ENTER when the desired Lo Scale value is displayed and the display reads “hi•XXXXXXXXXXXXX•”. Use the numeric keypad to enter the high end scale value, the default is the full scale value of the range selected. Press ENTER when the desired Hi Scale value is displayed and the display will return to the “Input scale” Menu item.

5.6.5.3 Output Scale

All linear current and voltage inputs must be assigned low and high output scale endpoints. The output scale is used to linearly map the input range (set with the Input scale option) to an Output range set with the Output Scale option. For example, if a transducer has a 1 volt output equivalent to 5000 PSI, use the 1.25V input range with an Input Range setting of 0 to 1.00 V and program the Output Range to be 0 to 5000. The actual readings on the display will now be in PSI.

Programming Output Scale - Use the UP (•) or DOWN (•) Arrow Keys to scroll through the menu items in the Point Setup Menu and highlight “Output scale”. Press ENTER and the display reads “places? X”. Use the UP (•) or DOWN (•) Arrow Keys to scroll through the menu items to set the number of decimal places (up to a maximum of 4

- NOTE 5 = E notation) and press ENTER. The display will read “lo•XXXXXXXXXXXXX•” (13 places possible). Use the numeric keypad to enter the low end scale value, the default is zero. Press ENTER when the desired Lo Scale value is displayed and the display reads “hi•XXXXXXXXXXXXX•”. Use the numeric keypad to enter the high end scale value, the default is the full scale value of the range selected, which is a direct linear mapping or a scaling of 1. Press ENTER when the desired Hi Scale value is displayed and the display will return to the “Output scale” Menu item.

5.6.5.4 Decimal Fix

Certain points must be assigned a decimal place of up to four places or scientific notation. The choices are: 0=X (no decimal places) 1=X.X 2=X.XX 3=X.XXX 4=X.XXXX 5=Scientific Notation (Decimal places affect displayed point data values only.)

Programming Decimal Fix – Use the UP (↑) or DOWN (↓) Arrow Keys to scroll through the menu items in the Point Setup Menu until “Decimal fix” appears. Press ENTER and the display reads “places? X”. Use the UP (↑) or DOWN (↓) Arrow Keys to select the desired number of decimal points required. When the desired Decimal Fix is

CF 46 46 2/06

displayed, press ENTER to invoke. The display returns to “Decimal fix” in the Point Setup Menu.

NOTE: Thermocouple (T/C) points must be assigned a decimal place of either 1 or 0. This enables temperature to be displayed with a resolution on either 1 degree (0) or 0.1 degree (1).

5.6.5.5 Exc. Currents

Currents are used to measure a resistance input on the back of the Recorder. If a resistance other than an RTD is plugged into an input, Exc. Currents must be enabled. The current is typically 1.00mA. The procedure to enable or disable currents follows.

Enabling or Disabling Currents - Use the UP (•) or DOWN (•) Arrow Keys to scroll through the menu items in the Point Setup Menu and highlight “Currents”. Press ENTER and the display reads either “currents=NO” or “currents=YES”. Use the YES or NO Key to change the display to the desired state of Currents. When the desired Currents state is displayed, press ENTER to invoke and the display returns to “Currents” in the Point Setup Menu.

5.6.5.6 Filter

The digital filter smoothes noisy or erratic signals by attenuating the effects of sudden transitions. The digital filter is programmable from 0 to 30 seconds in one-second increments (nominal).

Programming Filter Seconds - Use the UP (•) or DOWN (•) Arrow Keys to scroll through the menu items in the Point Setup Menu and highlight “Filter”. Press ENTER and the display reads “seconds•XX•. Use the numeric keypad to enter the required number of seconds (maximum 30) then press ENTER to return to the “Filter” menu item.

5.6.5.7 Compensation

Thermocouple compensation can be local, from the cold reference junction temperature sensor built into the Recorder, or external through a direct input. When thermocouples are compensated locally, the temperature sensor (located on the rear terminal panel of the Recorder) measures the ambient temperature of the cold junction. For remote compensation, a single Thermocouple or RTD can be used to measure the ambient temperature of the remote junction box. This method allows several thermocouple points to be measured without using thermocouple extension wire for each input. The point used as the measurement source of the remote cold junction source is referred to as the compensation channel. The point used as the compensation channel must be programmed before the Thermocouple or RTD input is assigned to it. When the system prompts for compensation parameters, the UP (↑) or DOWN (↓) Arrow Key allows you to define this parameter (local or remote). Once thermocouple compensation has been set, continue the programming sequence.

Programming Compensation – Use the UP (↑) or DOWN (↓) Arrow Keys to scroll through the menu items in the Point Setup Menu and highlight “Compensation” and press ENTER. Use the UP (↑) or DOWN (↓) Arrow Keys to highlight either “Local comp” or “Ext comp”. If “Local comp” is chosen, press ENTER and the display returns to the “Compensation” prompt in the Point Setup Menu. If “Ext comp” is chosen, press ENTER and the display prompts for “ext point? X”. Use the UP (↑) or DOWN (↓) Arrow Keys to scroll through the point numbers to choose the input where the external compensation is input. When the desired point number is displayed, press ENTER and the display returns to the “Compensation” menu item in the Point Setup Menu.

5.6.5.8 Span/Offset

In order for the Span/Offset menu option to be available, the user must turn this feature on in the Measurement Program menu, refer to Section 5.8.2, Span and Offset. Once this option has been turned on, the user can use Span and Offset to compensate for long thermocouple cable runs or thermocouple inaccuracies. The default value for offset is 0 and the default value for span is 1. The offset is a value of absolute degrees which is added or subtracted to the thermocouple reading. The span is a multiplier of the absolute thermocouple range. Once span and offset have been entered, the new adjusted range will be

New T/C Range = (Full Scale * SPAN) + OFFSET

Note that span is a multiplier while offset is an additive.

To adjust the span and offset (this assumes this option has been turned on in the Measurement menu) use the UP (↑) or DOWN (↓) Arrow Keys in the Thermocouple option menu to select Span/Offset and press ENTER. The display will show “Ofs →0.0000←”. Use the numeric keys to enter a value for the offset which will be added or

CF 46 47 2/06

subtracted to the thermocouple value. Note that offset is typically measured around the ice point which should be 0o C or 32o F. The offset would be typically the difference between the thermocouple reading at this point and the true ice point value. Press ENTER. The display will then show “Spn →1.00000←”. Use the numeric keypad to enter the new span value. The span should typically be measured near the full scale value of the thermocouple using a known temperature or reference. The span would be the absolute value of the reference divided by the reading of the thermocouple. Press ENTER to register these values and return to the Thermocouple option menu.

5.6.5.9 Eng Units

A maximum five-character alphanumeric engineering units message may be assigned for voltage and current inputs to identify the point, e.g. PSI or mA.

Programming Engineering Units - Use the UP (•) or DOWN (•) Arrow Keys to scroll through the menu items in the Point Setup Menu to highlight “Eng units”. Press ENTER and the display reads “units•XXXXX•”. Use the alphanumeric keypad to enter up to five characters for desired Engineering Units then press ENTER to return to the Point Setup Menu.

5.6.5.10 Alarms

A total of five alarms can be set for each point programmed. These alarms can be any mixture of the following alarm types:

None no alarm set High set high alarms (up to five). Alarm will occur if input is greater than the Alarm set point. Low set low alarms (up to five). Alarm will occur if input is less than the Alarm set point. Rate set rate alarms (up to five). Alarm will occur if the input changes by more than the set point value

in the specified time.

Abnormal set alarms for abnormal conditions (TCBO, Overflow, invalid etc)

In the case of Linear Dry Contact

None no alarm set Open set Alarm on open contact Close set Alarm on closed contact

In the case of Conditional Inputs the choice is:

None no alarm set True set Alarm if condition is true as defined False set Alarm if condition is false as defined

If you try to program an alarm with an illegal condition, for example, setting a Linear Voltage input alarm to “type=close”, you will get an ILLOGICAL error.

Alarms programming also allows the user to program an Alarm Deadband and Alarm Delay for each alarm set. The Alarm Deadband is the hysteresis.

Programming Parameters – Alarms programming requires setting parameters for: Alarm Limits Alarm Deadband Alarm Delay

5.6.5.10.1 Alarm Limits

The interval time is entered in a 24-hour clock format in Hours (00 through 24) and Minutes (00 through 59). The longest time interval that can be entered is 24:00 which represents a reset interval of once every 24 hours.

Interval Programming for Hi Peak / Lo Peak Point Types - When programming a High Peak/ Low Peak Point, the Interval represents the frequency the High or Low Peak value will be reset to the value of the base point. The High or Low Peak value will be logged on the Alarm/Event Data Log before the value is reset is the reset print is enabled. The interval time is entered in a 24-hour clock format in Hour (00 through 24) and Minutes (00 through

59). The longest time interval that can be entered is 24:00 which represents a reset interval of once every 24 hours.

For the Interval Log function and Auto Resettable point types, the programmable Start Time is not necessarily the time at which the first log / reset will occur. However, a log / reset will always occur at the Start Time every day. The actual first log / reset depends upon the current time and the assigned Interval. The Recorder calculates the first log / reset by repeatedly adding the interval to the Start Time until the current time is met or exceeded. See the example below:

Current Time: 07:30 Start Time: 09:15 Timed Interval: 1 Hour

09:15 Programmed Start Time 10:15 11:15 12:15 Note: The Interval (1 hour) added to the Start Time yields log/reset times. . 23:15 00:15 01:15 . 07:15 07:30 (Current Time) 08:15 Time of the first log / reset for this example

5.6.6 Linear Current/Voltage Point Types

The Recorder accepts two standard types of linear current inputs: 4 to 20mA, 0 to 20mA and 10 to 50mA.

Dry Contact will be covered later in this chapter.

Deciding Which Voltage Range to Use – In deciding which of the voltage ranges to use, select the smallest range that will accommodate the full span o fht einput signal for the best resolution and accuracy of the Analog-to-Digital Converter (ADC).

Current Inputs Voltage Shunt – Current inputs are converted ot voltage by means of an external 50 ohm shunt resistor supplied by the user. The following formula is used to determine the appropriate low and high end input voltage for non-standard current inputs: Ohms Law: E=I*R E=Equivalent voltage inputs I=Current in milliamps R=Precision shunt resistance value

Shunt Resistor Example – The following example shows a low and high end input voltage for a 0 to 1mA input with a precision shunt resistance of 1000 ohms with the measurement done on the 1.25V range. E=0x1000=0mV=0 V (Low input) E=1x1000=1000mV=1 V (High input)

Using the Input and Output scaling, the user can program full scale ranges for the above input. Programming Parameters – Once a point has been programmed as Linear and a current or voltage mode selected, the user is presented with the following parameters:

Point Tag Section 5.6.5.1 Input Scale Section 5.6.5.2 Output Scale Section 5.6.5.3 Exc. Currents Section 5.6.5.5 Filter Seconds Section 5.6.5.6 Engineering Units Section 5.6.5.9 Alarm Setpoints Section 5.6.5.10 Chart Scale Section 5.6.5.11

Not all the above options will be available. It depends on the choice of input range.

5.6.7 Dry Contact Point Type

The Dry Contact Point Range type allows a point to be programmed and act like an open or closed contact. The input can be a set of potential free contacts. Logically an open contact is equal to 0 (zero) and a closed contact is equal to 1.

Once a point has been selected as Linear as described above (5.6.6) use the UP (•) or DOWN (•) Arrow Keys to

CF 46 55 2/06

highlight “Dry contact” as the linear type and press ENTER. The display will show a reduced Point Setup menu the Dry Contact Point Setup Menu. The user can then set the following parameters:

5.6.8 Industrial Square Root Current/Voltage Point Types

The Recorder accepts three voltage square root extraction ranges:

±150mV sqrt, ±1.25 Volt sqrt, ±2.5 Volt sqrt, ±12.5 Volt sqrt and ± 25 Volt sqrt

and two types of linear current square root extraction ranges:

4 to 20mA sqrt, 0 to 20mA sqrt and 10 to 50mA sqrt.

This function is used for inputs which require the Industrial Square Root of the input signal (i.e. flow measurement). The system calculates the square root of the percentage of input scale and multiplies this value by the high end scale to produce the value of the point displayed. In the following example, the input is 4 to 20mA and the scaling is such that 0 = Low End of Scale and 1000 = High End of Scale.

High End Scale = 1000 gallons per minute

Input Signal = 12mA or 50% of scale which is equal to 0.5

Square Root of 0.5 = 0. 707

Actual value displayed is 0.707 x 1000 = 707 GPM (with decimal fix of 0)

Current input signals requires that the user provides an external resistor.

The Point Setup menu for Time Average will be displayed and may require programming the following parameters:

5.6.12.7 Gated Timer

The Gated Timer function allows a timer, measuring in seconds, to be controlled by a ‘gate’ from a logic point. For example, if a point is measuring temperature and you wanted to know the total amount of time the temperature measured by this point is above or below a certain level, a Conditional Point can be programmed to be ‘true’ only when the temperature is above or below a set level. A Gated Timer Point can then be programmed to be turned ON only when the Conditional Point is in the true state. The Gated Timer Point will then only be timing when the temperature is above or below a set level. The timer will continue to accumulate time, in seconds, each time it is turned on. The Gated Timer Point can be reset at programmable time intervals and alarms can be set to alarm if the timer total goes above a programmed time interval in seconds.

No data will actually be stored until the Record mode is turned on in the FUNCtion Menu.

5.7.3 Record Mode

There are three options “Fill Mode”, “Inst/Avg All” and Inst/Avg Indiv”. The “Fill Mode” determines whether files are to be recorded to fill the disk and stop, or recycle, deleting the oldest data and replacing it with new. The Instantaneous/Average options determine whether data will be averaged over the record interval or whether the latest data only is stored. If you are using one of the intrinsic functions of the unit, for example Peak Values, you must set the sample mode to instantaneous or you will “average” your “peaks” if you have a slow sample storage rate.

5.7.3.1 Fill Mode

Use the UP (↑) or DOWN(↓) Arrow Keys to highlight “Fill Mode” from the Record Mode Menu. There are two options available, “Fill to End” and “Cycle Data”.

Press the ENTER button to activate your choice and automatically select the next point. Press EXIT to return to the Record Setup Programming menu.

5.7.6 Record rate

The user can select the rate at which data is stored to disk independently to the rate at which it is displayed on the chart. The rate can be set for all channels at once or it can be set for each channel individually. The rate can be set from the fastest rate of 8 times per second to the slowest rate of once every 600 seconds or once every ten minutes. The rate you choose is dependent on how dynamic the process that you are measuring is. If you are recording temperature that varies slowly, you can maximize the amount of data that is stored on the disk by keeping the record rate slow. If you are measuring variables that change rapidly, you may need to set the record rate at once per second. Thus if you have one channel that is recording a rapidly changing input and one that is recording an input that changes slowly, you can optimize the record rate for each.

There are two record rates for each channel or point, a low rate and a high rate. The default rate is set in the FUNCtion menu - Record Speed. The record rate can be changed by an external event if the digital I/O option is fitted. Refer to 5.9.2. External speed change is enabled in the Autorate option.

To set record rates use the UP (↑) or DOWN (↓) Arrow Keys to highlight “Record Rate” on the menu and press ENTER. There are three options: “Autorate”, “Individual Rate”, and “All rates”.

5.7.6.1 Autorate

Autorate enables the record rate to be changed on an Alarm event. To enable auto rate change, use the UP (↑) or DOWN (↓) Arrow Keys to highlight “Autorate” and press ENTER. You will be presented with a display that shows “autorate=NO” or “autorate=YES”. Press the YES or NO keys to enable or disable the autorate change on alarm option then press ENTER to return to the record rate menu.

5.7.6.2 Individual Rates

To set the individual record rates per channel use the UP (↑) or DOWN (↓) Arrow Keys to highlight “Individual Rate” and press ENTER. You will be presented with a point selection keypad that enables the selection of the specific point to be programmed. Enter the point number and press ENTER. This brings up the record rate entry keypad and a display that shows “secs(lo)•XXX•” where XXX is the current sampling rate in seconds. Use the numeric keypad to enter the record rate from 0 to a maximum of 600 seconds, then press ENTER to activate. The display will show “secs(hi)•XXX•” where XXX is the current record rate in seconds. Use the numeric keypad to enter the record rate from 0 to a maximum of 600 seconds, then press ENTER to activate and return to the Record Speed menu. Repeat the above procedure for each point to be programmed. Press EXIT at any time to return without altering the setting and to return to the Record Setup menu.

5.7.6.3 All Rates

To set the record rates for all channels at once, use the UP (↑) or DOWN (↓) Arrow Keys to highlight “All Rates” and press ENTER. You will be presented with a display that shows “secs(lo)•XXX•” where XXX is the current record rate in seconds. Use the numeric keypad to enter the record rate from 0 to a maximum of 600 seconds, then press ENTER to activate. The display will show “secs(hi)•XXX•” where XXX is the current record rate in seconds. Use the numeric keypad to enter the record rate from 0 to a maximum of 600 seconds, then press ENTER to activate and return to the Record Rate Programming menu. Press EXIT at any time to return without altering the setting and to return to the Record Setup menu.

NOTE: To set the record rate to 8 times a second select 0 seconds.

NOTE: Although the record rates are shown as low and high, the “low” rate can in fact be faster than the “high”

rate. The low and high rates are defined by selection in the FUNC menu. If the digital I/O option is fitted the switch inputs can be set to change record speed. An active input selects the “high” speed, an inactive input selects the “low” speed. The current record rate (high or low) is indicated in the Disk Status Window, the high rate being indicated by REC↑ and the low rate indicated by REC ↓. The inputs can be overridden by the FUNC menu until a

CF 46 63 2/06

change of input state takes place. If you do not plan to use the change record rate option, set both record rates to the same value.

The logic for external record rate change is as follows:

SWITCH RECORD RATE

FUNC

high lo to hi high high hi to lo low

low lo to hi high low hi to lo low

Press the YES then ENTER buttons. The unit will look on the disk for any configuration files that will be displayed on the File Browser Directory. If more than one file exists on the disk, the directory will list them one above the other, with the current file to be loaded indicated by the “<” sign alongside it as shown below. If no configuration file is found the unit will indicate (No Files Found). The Config file directory looks like this:

File Directory

Configurations OLDFILE .CFG< NEWFILE .CFG

If more than one configuration file exists use the UP (↑) or DOWN (↓) Arrow Keys to select it and press the ENTER button. If there are more files on the disk than what will show on the screen, the list will scroll down with the “<” sign. The unit will load the selected configuration file from the disk and the disk status window will show LOAD CFG. If the load is successful, a window will pop up indicating “Configuration Loaded”. Press the “OK?” button. At this point the unit will automatically RESET and begin with the newly loaded parameters

Note: Once the configuration load has been initiated, the unit will automatically load and restart. Be sure you

select the correct configuration file. It is advisable to save your current con figuration before loading a new one. Use a new disk or different filename to save the old configuration.

 The passcodes and calibration constants are NOT loaded from the configuration file to maintain

access and calibration integrity.

5.7.11 Filename

The user can enter a filename to identify the recordings he is making. The filename can be any valid DOS filename up to a maximum of 8 characters, e.g. BATCH1 or SAMPLE5. This filename is applied to all pen files, the alarm file and the configuration file. Thus if the name “BATCH1” is entered, pen 1 file will be BATCH1.DT1, pen 2 file will be BATCH1.DT2 and so on, the alarm file will be BATCH1.ALM and the configuration file will be BATCH1.CFG. A disk can hold files with different names. For example, you may run three batches and name files for each batch, BATCH1, BATCH2 and BATCH3 all on the same disc.

To enter a filename use the UP (↑) or DOWN (↓) Arrow Keys to highlight “Filename” and press ENTER. You will be presented with a display that shows “‡FILENAMEfl” where FILENAME is the current file name. Use the alphanumeric keypad to enter a new file name.

7.4 Tutorial

7.4.1 Scroll bars

A scroll bar is used to move the object in the associated window (lists, etc). There are two types of scroll bars, vertical and horizontal. The vertical scroll bar will be described, but the horizontal scroll bar is analogous.

The scroll bar has five parts to it (see Figure 7-2). An up arrow (A), a top region (B), a thumb button (C), a bottom region (D), and a down arrow (E). The up arrow moves the associated object in the windows up one unit. The down arrow moves the object down one unit. The ‘unit’ may be a single line of text or a segment of the graph. To move the object by this single increment, place the mouse cursor (using the mouse) over either button and press the left button once.

The thumb button shows where the visible part of the object is relative to the beginning and end. Every time the object is moved, the thumb button reflects its new position. The thumb button may be held and dragged by pointing to it with the mouse cursor (using the mouse) then pressing and holding the left mouse button while dragging the mouse and consequently the thumb button up or down. The object will be moved accordingly.

Pressing the left mouse button when the mouse cursor is pointing to the top region (the area on the scroll bar between the up arrow and the thumb button), the object will move up by one “page”. The object will move down on “page” when this is done I on the bottom region.

Figure 7-2 Scroll

Bar

7.4.2 Using Dialog Boxes

A dialog box is a special window where several selections can be made, or different types of data can be displayed or entered. Although dialog boxes may all appear very different, they all have some common functions.

To edit any selection in an area of a dialog box, that area must be made current. This can be done by pointing to that area of the dialog box (e.g. a list of radio buttons) with the mouse cursor and pressing the left mouse button, or keep pressing the [TAB] key until that part is current (highlighted), or Press and hold [ALT] and the underlined letter in the label for that part. All keyboard entries are directed to the current object (part) of the current window. Therefore, what a key does depends on which area is currently active.

7.5 Appendix

7.5.1 File Types

The software works with various file types, both on the data card and from the computer disk. Some of the file types are PC specific, while others are used both by the computer and the Recorder. The files may have any name up to a maximum of eight characters. It is the last three characters appended to the filename that define the file types, and these are preset by the system. The following are the file types that are used:

wgetdata.INI Text file use by the this software only. Contains initialization data. *.DT* Data files from the Recorder. Use the export command to translate the file. *.DAT,* .CSV Exported data file. Created by this software when you export data.
