Product Description 1.1

1.1.1 GENERAL

The instrument is a microprocessor based circular chart recorder capable of measuring, displaying and recording from a variety of inputs. Applications include temperature, pressure, flow and others. The instrument can be specified as either a single or dual pen unit.

Recording, alarm, or limit settings and other parameters are easily entered via the keypad. All user 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 variable input for each terminal 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, is 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 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 recorder is housed in a structural foam enclosure suitable for panel or surface mounting.

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 used to isolate the instrument.

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/SEGREGATION

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 reduce cross talk. Cross talk is due to the Electro Magnetic Field 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 electrical 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 coils connected in parallel and as close as possible to the coil. See Figure 2-2, page 10. 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 capcitor (1000 volts) is recommended. For circuits from 3 to 5 amps, connect 2 of these in parallel. See Figure 2-3, page 10.

2.5.2 SENSOR PLACEMENT (THERMOCOUPLE OR RTD)

Thermocouple lead resistance should not exceed 300 ohms. It this is exceeded, instrument accuracy could be affected.

Two wire RTD's should be used only with lead lengths less than 10 feet. 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 most agitated area. In air - the best circulated area.

THERMOCOUPLE LEAD RESISTANCE

Thermcouple 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 below

L = length of leadwire in thousands of feet

Example: An MRC is to be located in a control room 660 feet away from the process. Using 16 AWG, type J thermocouple, how much error is induced?

Terr = Tle * L

TLe = 4.93 (°F/1000 ft) from Table 2 Terr = 4.93 (°F/1000 ft) * 660 ft Terr = 3.3 °F

RTD LEAD RESISTANCE

RTD lead length can affect instrument accuracy, since the size (gauge) and 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 Table 3 if 3 wire RTD or Table 4 if 2 wire RTD

L = length of lead wire 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 3 Terr = +/-.46 (‡F/1000 ft) * 2000 ft Terr = +/-0.92°F

Wiring Connections 2.6

All wiring connections are typically made to the instrument at the time of installation. Connections should be made at the terminal blocks , two 12 gauge wires maximum. Terminal blocks are designated TB1 through TB13. See Figure 2-4 for the terminal block locations (SPST Relay Board shown).

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 of 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. 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 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 which are accessed via the front keypad.

Prior to first time operation of the unit, the configuration procedures for the Program and Alarm Set 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 4.6 of this manual (page 43).

Shipped Configuration/Jumper Positioning 3.2

Each instrument is factory shipped ready to accept a thermocouple input on TB 4 and TB 5. All configuration 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 provide a security lockout feature and to condition the sensor inputs. All jumpers are typically of the three pin type and have two functions. All jumpers are located on the instrument Processor board. The instrument board layout and jumper locations are shown in Appendix A-1 (page 50). Check the actual jumper position in the unit to be configured and verify the proper position for the intended application. .

The sensor input jumpers JU4, JU5, JU6 and JU7 condition the sensor input at a basic level. Detailed input type selection is made in the Program mode.

Operation Summary 3.3

Prior to operation the Program mode parameters and Alarm Setting(s), if used, must be selected for the application. Data and parameter entry is made by stepping through each mode and making an appropriate response or entry to each step.

3.3.1 KEYPAD OPERATION

Refer to Figure 3-1 for the Keypad features. Use the SCROLL, UP and DOWN keys as indicated to program and operate the instrument.

All configuration parameters are listed in Tables 3-1 through 3-3 (pages 24-32). For a single pen instrument, parameters for each mode are displayed in the upper right

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 and no keypad activity takes place for 30 seconds, the instrument will time out and exit the mode automatically. The display will be 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 Operation or Off mode, depending upon which operational state was in use before entrance into the mode.

3.4.1 POWER UP PROCEDURE

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

Step 2A - For instruments with software revision R2.99 and below Upon power up, 7XXX 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 then tSt1, tSt2, and tSt3 will be displayed while Test 1 through 3 are executed automatically. Upon successful completion of these test, oPEr or oFF will be displayed for about 3 seconds. The mode displayed will be the mode the instrument was in when the power was turned off. During this time, the operator may select another mode (Alarm Set, Enable) or non-operational mode (Test, Program, Cal).

Step 2B - For instruments with software revision r3.00 and above Upon power up, a brief flash on all displays (upper and, if equipped, lower) will occur to show the instrument is "alive". Then 7XXX 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 at 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, oPEr or oFF will be displayed for about 3 seconds. The mode displayed will be mode that the instrument was in when the power was turned off. During this time the operator may select another mode (Alarm Set, Enable) or non-operational mode (Test, Program, Cal).

Step 3 If any error messages are displayed, refer to Section 4.6 (page 43) for a definition of these error messages and the required action.

In the rEC (receive) mode, the transmitter is continuously disabled. In either mode, the instrument will monitor the line and display rEC1 when a logic 1 is on the line or rEC0 when a logic 0 is on the line . In the SEnd mode, the instrument will display rEC when the transmitter is disabled. To perform an internal test and verify the basic operation of the hardware, place the instrument in the Send mode and verify that the display cycles through rEC1, rEC0, and rEC. To verify that the transmitter functions properly, two LED’s, each with a current limiting resistor, can be connected with opposite polarity observed to the TB 2 terminals 1 and 2.

The following three states should be observed: one LED on, then the other LED on, then both off. Alternately, a load resistor can be placed on the terminals, and observe that the voltage generated across the load resistor is as follows: >+3 VDC, then >-3 VDC, and then 0 VDC. Another method, to test the communications hardware, would be to connect one or more instruments in the Receive mode to an instrument in the Send mode. All of the instruments in the Receive mode should have their displays alternating in sync with the instrument in the Send mode. When the sending instrument displays rEC, the receiving instruments should display rEC1. To terminate the test, press the SCROLL key for one second. Upon exit, tStA will be displayed. The existence of the communications hardware is dependent on the

hardware configuration.

If the relay is connected to a high impedance AC device, the snubber network used to protect the relay contact may cause the output to appear to be activated when the relay is off. To cure the problem, cut the snubber resistor for the output that is being affected.

Appendix B Glossary

DISPLAY FILTER FACTOR

This parameter is adjustable from 1 to 20 which represents the number of scans per second of the process variable that are averaged together before updating the displayed and recorded value. The factory default value is 1 = no filtering. Display code dFF.

HYSTERESIS

This parameter is adjustable from 0 to 300 units representing the width of the band (half above and half below setpoint). Used with Alarm outputs to reduce cycling. For instance, with a value of 4 and an alarm point of 70 the output will turn ON when the process variable drops to 68 and stay ON until 72 is reached, then turn OFF the output. Does not apply to Limits. Factory default = 3. Display code HyAo.

INPUT CORRECTION

This parameter is adjustable from -300 to 300 units and is used as a method to compensate for a linear sensor error. Factory default is 0 = no correction. Display code iCor.

PEN ACTION ON POWER UP

This parameter specifies whether this pen, on a power-up, will drive to the "Home " position (center of chart), then return to its correct position. This is done as a Cal Check. Settings are 0=go to "home" and 1=remain in last position prior to power down. Default=0.

PLATEN

The flat surface in the instrument upon which the chart rotates.

PROCESS FILTER FACTOR

This parameter is adjustable from 1 to 20 which represents the number of scans per second of the process variable that are averaged together before updating the process value used for alarm and PV output purposes. The factory default value is 1 = no filtering. Display code PFF.

PROCESS OUTPUT

Allows re-transmission of the process variable. Factory default is 0 = not selected. Display code Pout. If selected, must be assigned to a current output and scaled using Process Output upper and lower values.

PROCESS OUTPUT UPPER AND LOWER VALUES

(Used in conjunction with process output) These parameters specify the process value range over which the assigned current output will decrease linearly from 100% to 0%. If the process value is greater than Pou the output will be 100%/ If the process value is less than PoL the output will be 0%. Factory default values are 2000 for the upper value and 0 for the lower value. Display codes Pou (upper) and PoL (lower).

PROCESS ROUNDING

This parameter is adjustable from 0 to 100 units and is used to round the process value to the nearest value specified. This is for display only and does not affect the recorded value or control action. Intended for use where the engineering units span is large, to reduce display fluctuation. Factory default is 0 = no rounding. Display code Prnd. (e.g. Prnd = 3, Process

Value = -6, -3, 0, 3, 6, 9....).
