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.
