Product Description 1.1

1.1.1 GENERAL

The instrument is a microprocessor based circular chart Recorder or Recording Controller capable of measuring, displaying, recording and controlling from a variety of inputs. Applications include temperature, level, pressure, flow and others. The instruments can be specified as either a single or as a dual pen model.

Recording, control functions, alarm settings and other parameters are easily entered via the keypad. All user's data can be protected from unauthorized changes by the Enable mode security system, and is protected against memory loss, as a result of AC power outage, by battery back-up.

The process sensor input for each pen is user configurable to directly connect to either thermocouple, RTD, mVDC, VDC, or mADC inputs. Changes in input type can easily be made by the user. Thermocouple and RTD linearization, as well as thermocouple cold junction compensation, are performed automatically. The instrument process variable inputs are isolated. An isolated 24 VDC regulated transmitter power supply can be provided in the instrument for use with up to two 4 to 20 mADC process sensor transducers.

The instrument can be ordered to operate on either 115 VAC or 230 VAC power at 50/60 Hz. The 230 VAC option includes a switch for selecting either 230 VAC or 115 VAC operation. The instrument is housed in a structural foam enclosure suitable for panel or surface mounting.

FIGURE 1-1

The number of keys and LED's will depend upon the configuration of individual unit.

1.1.2 RECORDING

The instrument records the selected process variable on a 12-inch circular chart. One box of standard charts is provided with each recorder. Charts are available in a wide selection of ranges. Chart rotation speed is programmable from 0.1 to 999.9 hours per revolution in 0.1 hour increments. The instrument can be ordered with one or two pens. Pen 1 is red and Pen 2 is green. Pens are the disposable fiber-tip type.

1.1.3 DISPLAYS

Each instrument has a digital display and status indicators for each pen (See Figure 1-1, page

5). On Recording Controllers, the display may be configured to display the Process Value, Process Value and Setpoint, Deviation from Setpoint only, Deviation and Setpoint, or Setpoint only. During configuration the display(s) is/are used to show the enabled modes of operation and the parameter codes.

The display at the left is for Pen 1, the display at the right is for Pen 2 (if provided). On Recorders, the display includes status indicators for Alarm 1 and Alarm 2, degrees C, degrees F, engineering units, and setpoint (for limits). On Recording Controllers, the display includes status indicators for Manual mode operation, Output 1, Output 2 , Alarm, degrees C, degrees F, engineering units, setpoint and minus sign. See Figure 1-2 ( page 7).

Display resolution is programmable for 0.1 or 1 degree for thermocouple and RTD inputs, and none, one, two or three decimal places for other input types.

1.1.4 CONTROL

The instrument can be provided with relay, solid state relay driver and milliamp DC outputs. Instruments can be programmed for on-off, time proportioning, current proportioning or position proportioning control depending upon the hardware present. Switching between the Control mode and the Manual mode of operation is easily accomplished with a dedicated key on the keypad. Switching is bumpless from the Control to the Manual mode, and while in manual, manipulation of proportional outputs is possible. Each pen of a dual pen recording controller is provided with its own AUTO/MANUAL key . Other standard control features include proportional control output limits, setpoint limits, anti-reset windup and a unique Automatic Transfer function. If configured, the Automatic Transfer function allows manual control of the proportional output until the process reaches the setpoint at which time the instrument will go into the Control (automatic) mode of operation.

1.1.5 ALARM

An Alarm indicator is standard for each pen. Two alarm functions are provided for each pen and the alarm indicator will light if either alarm for that pen is on. Alarm settings are programmable. Alarm type may be selected as process direct or reverse (high or low), deviation from setpoint direct or reverse, and deviation band open or closed within the band. Alarm outputs can be provided by assigning any relay(s) Single Pole/Single Throw (SPST) or Solid State Relay (SSR) driver to the respective alarm.

1.1.6 PROCESS VALUE RE-TRANSMISSION OUTPUT

If an instrument is specified with mADC current output(s), any of the outputs may be programmed to operate as a process value re-transmission output. The output is scaleable but

can not be used as a control output while assigned as a process value re-transmission output.

1.1.7 DIGITAL COMMUNICATIONS

The instrument can be ordered with a Digital Communications option that provides the capability of bi-directional communications with a supervisory computer. A dual pen instrument can have an individual address selected for each pen. Refer to the Communications Protocol Manual (Form 2878) for more details regarding the communications option. This manual is included with the unit when the communications option is specified.

Preparations for Wiring 2.5

2.5.1 WIRING GUIDELINES

Electrical noise is a phenomenon typical of industrial environments. The following are guidelines that must be followed to minimize the effect of noise upon any instrumentation.

2.5.1.1 INSTALLATION CONSIDERATIONS

Listed below are some of the common sources of electrical noise in the industrial environment:

• Ignition Transformers

• Arc Welders

• Mechanical contact relay(s)

• Solenoids

Before using any instrument near the devices listed, the instructions below should be followed:

1. If the instrument is to be mounted in the same panel as any of the listed devices, separate them by the largest distance possible. For maximum electrical noise reduction, the noise generating devices should be mounted in a separate enclosure.

2. If possible, eliminate mechanical contact relay(s) and replace with solid state relays. If a mechanical relay being powered by an instrument output device cannot be replaced, a solid state relay can be interposed to isolate the instrument. (Continued on next page)

3. A separate isolation transformer to feed only instrumentation should be considered. The transformer can isolate the instrument from noise found on the AC power input.

4. If the instrument is being installed on existing equipment, the wiring in the area should be checked to insure that good wiring practices have been followed.

2.5.1.2 AC POWER WIRING

Earth Ground The instrument includes noise suppression components that require an earth ground connection to function. To verify that a good earth ground is being attached, make a resistance check from the instrument chassis to the nearest metal water pipe or proven earth ground. This reading should not exceed 100 ohms. Each instrument should have a dedicated earth ground. Do not chain link multiple instrument ground wires.

Neutral (For 115VAC) It is good practice to assure that the AC neutral is at or near ground potential. To verify this, a voltmeter check between neutral and ground should be done. On the AC range, the reading should not be more than 50 millivolts. If it is greater than this amount, the secondary of this AC transformer supplying the instrument should be checked by an electrician. A proper neutral will help ensure maximum performance from the instrument.

2.5.1.3 WIRE ISOLATION/SEGRATION

The instrument is designed to promote proper separation of the wiring groups that connect to the instrument. The AC power wire terminals are located near the top of the instrument boards. The analog signal terminals are located near the bottom of the instrument boards. Maintain this separation of the wires to insure the best protection from electrical noise. If the wires need to be run parallel with any other wiring type(s), maintain a minimum 6 inch space between the wires. If wires must cross each other, do so at 90 degrees to minimize the

contact with each other and amount of cross talk. Cross talk is due to the EMF (Electro Magnetic Flux) emitted by a wire as current passes through it.

2.5.1.4 USE OF SHIELDED CABLE

Shielded cable helps eliminate electrical noise being induced on the wires. All analog signals should be run with shielded cable. Connection lead length should be kept as short as possible, keeping the wires protected by the shielding. The shield should be grounded at one end only. The preferred grounding location is at the sensor, transmitter or transducer.

2.5.1.5 NOISE SUPPRESSION AT THE SOURCE

Usually when good wiring practices are followed, no further noise protection is necessary. Sometimes in severe environments, the amount of noise is so great that it has to be suppressed at the source. Many manufacturers of relays, contactors, etc. supply "surge suppressors" which mount on the noise source.

For those devices that do not have surge suppressors supplied, RC (resistance-capacitance) networks and/or MOV (metal oxide varistors) may be added.

Inductive Coils - MOV's are recommended for transient suppression in inductive soils connected in parallel and as close as possible to the coil. See Figure 2-2. Additional protection may be provided by adding an RC network across the MOV.

Contacts - Arcing may occur across contacts when the contact opens and closes. This results in electrical noise as well as damage to the contacts. Connecting a RC network properly sized can eliminate this arc.

For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad capacitor (1000 volts) is recommended. For circuits from 3 to 5 amps, connect 2 of these in parallel. See Figure 2-3.

2.5.2 SENSOR PLACEMENT (THERMOCOUPLE OR RTD)

If the temperature probe is to be subjected to corrosive or abrasive conditions, it should be protected by the appropriate thermowell. The probe should be positioned to reflect true process temperature:

In liquid media - the mose agitated area. In air - the best circulated area.

THERMOCOUPLE LEAD RESISTANCE

Thermocouple lead length can affect instrument accuracy, since the size (gauge) and the length of the wire affect lead resistance.

To determine the temperature error resulting from the lead length resistance, use the following equation:

Terr = TLe * L where; TLe = value from appropriate Table

L = length of leadwire in thousands of feet.

Example A recorder is to be located in a control rrom 660 feet away from the process. Using 16 AWG, Type J thermocouple, how much error is induced?

Terr = TLe * L = 4.93 (°F/1000 ft) from Table 2. Terr = 4.93 (°F/1000 ft) Terr = 3.3 °F

RTD LEAD RESISTANCE

RTD lead length can affect instrument accuracy. Size (gauge) and length of the wire used affects lead length resistance.

To determine the temperature error resulting from the lead length resistance, use the following equation:

Terr = TLe * L where; TLe = value from Table 3 if 3 wire or Table 4 is 2 wire.

L = length of leadwire in thousands of feet.

TABLE 3 3 Wire RTD AWG No. Error °C Error °F

10 +/-0.04 +/-0.07 12 +/-0.07 +/-0.11 14 +/-0.10 +/-0.18 16 +/-0.16 +/-0.29 18 +/-0.26 +/-0.46 20 +/-0.41 +/-0.73 24 +/-0.65 +/-1.17

Example An application uses 2000 feet of 18 AWG copper lead wire for a 3-wire RTD sensor. What is the worst-case error due to this leadwire length?

Terr = TLe * L TLe = +/- .46 (°F/1000 ft) from Table 1 Terr = +/- .46 (°F/1000 ft) * 2000 ft Terr = +/- 0.92 °F

Configuration 3.1

After completing installation and wiring of the instrument the configuration (set up) procedures must be performed to prepare the instrument for operation on the intended application. The procedures include selecting specific parameters, entering data and possible jumper positioning. Once properly configured the instrument will retain the user selections in memory so this procedure need not be repeated unless required by changes in the application. Parameter selections and data entry are made via the front keypad. To ease configuration and operation, user entered data has been divided up into several sections referred to as modes. Each mode contains a different type of data or may be used for specific operating functions. For two pen instruments, some modes are common to both pens. These modes are as follows:

Associated with each mode is a series of unique displays that are accessed via the front keypad.

Prior to first time operation of the instrument, the configuration procedures for the Program and Tune modes must be performed as applicable. Calibration and Test modes are not used as part of the instrument configuration or operation. These are used for service and maintenance functions and are discussed in Section 5.4 & 5.5 of this manual (page 46 - 54).

lockout information)

Shipped Configuration/Jumper Positioning 3.2

Each instrument is factory shipped ready to accept a thermocouple input on TB 4 and TB 5. All parameters in each mode are set to default values. These defaults are shown in tabular form after the description for each mode. Instrument AC power input is as specified in the instrument model number and is shown on the ratings label. The 230 VAC option includes a switch in the instrument for selecting either 230 VAC or115 VAC input power. If this feature is provided, verify AC input and switch position before applying power to the instrument.

3.2.1 JUMPER POSITIONING

Jumpers are used to condition the sensor inputs and to provide a security lockout feature. All jumpers are located on the instrument Processor board. The instrument board layout and jumper locations and functions are shown in Appendix A-1 (page 62). Check the jumper positions in the instrument and verify that they are in the proper position for the intended application.

The sensor input jumpers JU4, JU5, JU6 and JU7 condition the sensor input signals and must be used in conjunction with input type selections made in the Program mode. (page 28).

Operation Summary 3.3

3.3.1 MODE SELECTION

If the instrument is either in the Off mode, the Operation mode (recorders), or the Control mode (recording controllers), repeated pressing and releasing of the SCROLL key will cause the instrument to display the code corresponding to each mode that is enabled. To enter a mode while the code is displayed, press the DOWN key. If a mode does not appear, refer to the Enable mode section for information on how to determine if the mode is on.

Entry into any mode except the Operate, Control, Tune, Manual, or Enable modes, will cause the output(s) to turn off and any process re-transmission value output(s) to be 0 %. Entry into the Off mode will cause process re-transmission to remain active.

Start up Procedures 3.4

All configuration parameters are listed in Tables 3-1 through 3-5. For a single pen instrument, parameters for each mode are displayed in the left display. If the

instrument being configured is a two pen model, a sequence of applicable parameters will be displayed in the Pen 2 display after the Pen 1 parameters have been reviewed and configured. After the Pen 2 parameters have been completed, parameters common to both pens will be configured and displayed in the Pen 1 display.

The instrument is provided with a time out feature. If the instrument is in any mode (except while executing a calibration or test procedure) and no keypad activity takes place for 30 seconds, the instrument will time out and exit the mode automatically. The display will become the code for the respective mode. If a mode code is displayed for 5 seconds with no keypad activity, then the time out will cause the instrument to proceed to either the Control or Off mode, depending upon whether the mode entered was an operational mode (Tune, Manual, Enable) or non operational mode (Test, Program, Cal).

3.4.1 POWER UP PROCEDURE

Step 1 Verify that all electrical connections have been properly made before applying power to the instrument.

Step 2 Upon power up, a brief flash on all displays (upper and, if equipped, lower) will occur to show the instrument is "alive". Then 8XXX will be displayed (X representing digits), then XXXX, then XXXX, identifying the twelve digit model number as defined in the order matrix. Next, the EPROM part number will be indicated P-XX. After the EPROM part number, the software revision level will be displayed in the format rX.XX followed by P.dn (if Pen Action on Power Up, PAPu, in Program Mode is set to 0, pens go to "home" position on power up). During this display, the decimal point after the "P" will blink to show the mode is active. Upon successful completion of this routine, CtrL, OPEr or oFF will be displayed for about three seconds. The mode displayed will be the mode that the instrument was in when the power was turned off. During this time the operator may select another mode (Tune, Manual, Enable) or nonoperational mode (Test, Program, Cal).

Step 3 If any error messages are displayed, refer to Section 5.6 (page 55) for a definition of the error message and the required action.

Front Panel Operation 3.5

3.5.1 DIGITAL DISPLAY AND STATUS LEDs

The digital display provided for each pen has 4 digits and a decimal point. Each digit has seven segments and is capable of producing numeric characters from 0-9 and certain alpha characters. The digital display is used to provide indication of process variable as well as displaying codes used for configuration and operation of the instrument. The display includes the following Status Indicator LED’s;

RECORDER: ALRM1 Red Rcdr - Lights when Alarm 1 is on.

Limit - Lights when Limit has been exceeded.

ALRM2 Red Lights when Alarm 2 is on. C Red Lights to indicate that the process value is in terms of
