Section 1 Overview
This instrument records process trend lines, one or two pens, on a 10 inch circular chart. As an option, up to two alarm points
are provided for each of the two pens.
This recorder will accept J, K, T, R, and S Thermocouples and RTD inputs, as well as typical Millivolt, Milliamp (4-20mA) and
Volt inputs, (up to 5 volts).
1.1 DISPLAY
Process values for each pen can be displayed on the .56" LED display, or the display can be blanked. In the latter case, the
display is used only for programming and setting alarm points.
1.2 CONTROL
The instrument can be provided with relay control outputs which can be programmed for on-off control capability.
1.3 ALARMS
Two optional alarm output relays, with SPDT contacts, are available for each pen. Each alarm is also configurable as a
latching, limit device. In this case, a manual reset button is required and included when the High/Low Limit option is ordered.
1.4 DIGITAL COMMUNICATIONS
An optional, RS-485 digital communications port is available that utilizes the standard MODBUS RTU protocol.
1.5 POWER INPUT
The standard recorder will operate on input power over the range of 90-264 VAC, 50-60 Hz, without any modifications. A low
power voltage option (20-50 VAC or 22-65 VDC) is also available. All Low Voltage option recorders are clearly identified as
such by a label near the power wiring terminal block.

Section 2 Installation and Wiring
Read these instructions completely and carefully before proceeding with the installation and operation of this recorder.
Electrical code requirements and safety standards should be observed. Installation should be performed by qualified personnel only.
Caution: The standard recorder will accept a power input over the range of 90-264 VAC. There is a special low power
voltage option that is available. Please verify the AC input power required by the recorder before proceeding with the
installation. The power required is listed in the Model/Serial number label affixed to the platen in the upper left hand
corner.
2.1 UNPACKING
Remove the recorder from the carton and inspect for any damage due to shipment. If any damage is noted, report and file a
claim with the carrier. Write the model number and serial number of the instrument on the inside front cover of this operation
manual for future reference.
2.2 LOCATION / MOUNTING
Locate the instrument away from excessive moisture, oil, dust and vibration. Do not subject the instrument to operating
temperatures outside of the 0 to 55°C (32 to 131°F) range.
The panel where the instrument will be mounted must provide rigid support for the approximate 7 lb. weight of the instrument.

2.3 PREPARATION FOR WIRING
Electrical noise interference is a phenomenon typical of industrial environments. Use the following guidelines which are
generally used to minimize the effect of electrical noise on instrumentation in general.
2.3.1 WIRING GUIDELINES
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 recorder is to be mounted in the same panel as any of the listed devices, separate them by the largest distance
possible.
2. If possible, replace electromechanical relay(s) with solid state relays.
3. Consider using a separate isolation transformer to power the recorder and any other instrumentation in the panel. The
transformer will serve to isolate the recorder from noise found on the AC power lines.
4. If the recorder is being installed on existing equipment, existing wiring should be inspected to insure that good wiring
practices have been followed.
5. Connect a good earth ground to the recorder chassis ground connection. To verify this, take a resistive measurement
from the instrument chassis to the nearest metal water pipe or proven earth ground. The reading should not exceed 100
ohms. Each instrument should have a dedicated earth ground. Do not chain link multiple instrument groundwires.
6. AC neutral should be at or near ground potential. To verify this, measure the AC voltage between neutral and ground.
The reading should be no more than 50 millivolts. If greater, the secondary of the transformer feeding the recorder should be
checked out by an electrician.
7. Wire Isolation/Segregation - this recorder is designed to promote proper separation of the wiring groups that connect to it.
The AC power terminals are located near the top of the instrument. The input signal terminals are located in the middle
section of the main board and the output alarm relay connections are on a separate board in the lower right hand corner of
the instrument.

8. Input Signal Wiring
run with shielded cable. Connection lead length should be kept as short as possible. The shield should be grounded at one
end only. The preferred grounding location is at the sensor, transmitter or transducer.
9. For severe levels of electrical noise, it may be necessary to suppress the noise at its source. Many manufacturers of
relays, contractors, 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 MOVs (metal oxide varistors) may be added.
Inductive Loads - MOVs are recommended for transient suppression for inductive loads, and should be connected in parallel
and as close as possible to the load. See Figure 2-2. Additional protection may be provided by adding an RC network across
the load.
Contacts - Arcing may occur across contacts (relays or switches) when they open and close. This results in electrical noise
as well as damage to the contacts. Connecting an RC network, properly sized, in parallel, can eliminate this problem. See
Figure 2-3.
For circuits up to 3 amps, a combination of a 220 ohm resistor and 0.5 microfarad capacitor (1000 volts) is recommended.
For circuits from 3 to 5 amps, connect two of these in parallel. The resistor should be 1/4 watt or 1 watt for 115 VAC or
230VAC circuits, respectively.
Shielded cable helps eliminate electrical noise being induced on the wires. All input wires should be

2.3.1 SENSOR PLACEMENT
If the input probe will be subjected to corrosive or abrasive conditions, it should be protected by the appropriate thermowell.
The probe should be positioned to reflect the true process temperature:
In liquid media - the most agitated area
In air - the best circulated area
For thermocouple sensors, the lead resistance should not exceed 300 ohms. If this is exceeded, recorder accuracy could be
affected. To determine the temperature error caused by lead length resistance, use the following equation:
Terr = TCe x L where; TCe = temperature error in °F or °C per 1000 feet
L = length of lead wire in thousands of feet

For 3 wire RTDs, the instrument can virtually eliminate all lead wire resistance error.
Two wire RTDs should be used only with lead lengths less than 10 feet, unless special input calibration is performed using the
iCor (Input Correction) capability. (See Section 4 for setting iCor.) To determine the temperature error resulting from the lead
length resistance, use the following equation:
Terr = TRe x L where; TRe = temperature error in °C or °F per 1000 feet
WARNING: Avoid electrical shock. AC power wiring must not be connected at the source distribution panel until all wiring
connections are completed.
All wiring connections are typically made to the instrument at the time of installation. All connections are made behind the
access door on the recorder right side. Loosen the two thumbscrews and open the access door to complete all wiring. Connections should be made at the terminal blocks , two 14 gauge wires maximum, copper conductors only, except thermocouple
inputs. Terminal blocks are designated TB1 through TB4. See Figure 2-4 for the terminal block locations. The number of
terminal blocks present on the instrument depends on the model/hardware configuration.

Section 3 Normal Operation
Assuming that the MODE switch (discussed later) is in the RUN position, on power up, the recorder will display the software
revision, in the format rX.XX, while the pens move to the home position (toward the center of the chart). Then the instrument
will display the model number. Only the first 8 digits will be displayed, 4 digits at a time, for two seconds each. Then the
display will blank while the recorder is measuring the input(s).
Then the pen(s) will go to their proper positions on the chart and the display will show the process value for pen 1 (if configured to display it) and will alternately show the pen 2 value (if it is present and if configured to display it), indicated by the
green, PEN 2 LED. If any output is active, the appropriate LED will be lit.
Note: Each time power is applied, the pen(s) will move to the home position (toward the center of the chart) and then position
themselves at the proper place on the chart.
The recorder will operate using the Program Parameters that were last stored in memory. The recorder is shipped from the
factory set up for a Type J thermocouple input, range code 1 (0-1400°F) on all pens. To modify the input types and ranges,
see Section 4 for detailed instructions.
Located on the backside of the access door (inside the recorder) is a Short Form Programming Card that summerizes the Run
and Program mode information.
See Appendix A for a complete description of the model number and options. See Section 6 for modifying the recorder model
number.
SENSOR FAULT DETECTION
The recorder will display, record, and act upon normal measured values. If an input is above or below the advertised span, the
display will indicate a Hi or Lo condition, respectively. If the input is disconnected (sensor break) or excessively out of range,
SnSr will be displayed.
Relays, output LED, and pens will react normally when in a Hi or Lo condition, as if the value was high or low, relative to the
setpoint. In a SnSr condition, relays will be de-energized, output LEDs will not be lit, and pens will go upscale.
NOTE: A sensor break can not be detected on zero based Volt and Milliamp inputs (0-5 volts and 0-20mA), as the
divider or shunt resistor, coupled with no input connection, produce a valid input signal of zero.
NOTE: A "Lo" condition can not be detected on zero based Volt, Milliamp, and Millivolt inputs, due to the nature of
the hardware. The instrument will handle slightly negative signals, but more negative inputs will result in the display
indicating a "Hi" condition. Refer to the Specifications section for more details.
3.1 CHANGING THE CHART
To make chart changing easier, the recorder can move the pens to the outside edge of the chart. It is not necessary to use
this capability. Do so only if you find it more convenient.
DO NOT PUSH THE PENS MANUALLY. This could affect mechanical adjustments or bend the pen arms, adversely affecting
accurate operation.
POSITIONING THE PENS FOR CHART CHANGING
While the MODE switch is in the RUN position, press the SCROLL key. CC will appear in the display, designating chart
changing. Press the DOWN arrow key. The recorder will move the pens fully upscale. The display will flash CC. Change the
chart per the instructions that follow and then press the DOWN arrow key again. The recorder will resume normal trend
recording.
CHANGING THE CHART PAPER
To change the chart, pull up on the chart clip located in the center of the chart. Remove the old chart and place the new chart
on the chart hub. DO NOT press down firmly. The UP arrow key can be used to advance the chart. Every time the UP arrow
key is pressed, the chart will advance one step. Line up the current time on the chart with the chart time arrow located to the
right of the display. Then press the chart down on the chart hub and flip the chart clip to the down position.

3.2 CONTROL OUTPUT SETTINGS
3.2.1 SINGLE OUTPUT
When Single Output On/Off control is configured as CH (Control Heat), the relay will turn OFF when the process value is
greater than the setpoint by one-half the hysteresis value and turn ON when the process value is less than the setpoint by
one-half the hysteresis value.
When Single Output On/Off control is configured as CC (Control Cool), the relay will turn ON when the process value is
greater than the setpoint by one-half the hysteresis value and turn OFF when the process value is less than the setpoint by
one-half the hysteresis value.
3.2.2 DUAL OUTPUT - HEAT/COOL
When Dual Output On/Off control is configured as CH (Control Heat) for Output 1 and CC (Control Cool) for Output 2, Output 1
relay will turn OFF when the process value is greater than the setpoint plus one-half the hysteresis value and turn ON when
the process value is less than the setpoint minus one-half the hysteresis value. Output 2 relay will turn ON when the process
value is greater than the setpoint plus one and one-half the hysteresis value and turn OFF when the process value is less than
the setpoint plus one-half the hysteresis value.
3.2.3 DUAL OUTPUT - HEAT/HEAT
When Dual Output On/Off control is configured as CH (Control Heat) for Output 1 and CH for Output 2, Output 1 relay will turn
OFF when the process value is greater than the setpoint plus one-half the hysteresis and turn ON when the process value is
less than the setpoint minus one-half the hysteresis value. Output 2 relay will turn OFF when the process value is equal to the
setpoint minus one-half the hysteresis and turn ON when the process value is equal to the setpoint minus one and one-half the
hysteresis value.
3.2.4 DUAL OUTPUT - COOL/COOL
When Dual Output On/Off control is configured as CC (Control Cool) for Output 1 and CC for Output 2, Output 1 relay will turn
OFF when the process value is equal to the setpoint minus one-half the hysteresis and turn ON when the process value is
equal to the setpoint plus one-half the hysteresis value. Output 2 relay will turn OFF when the process value is equal to the
setpoint plus one-half the hysteresis value and turn ON when the process value is equal to the setpoint plus one and one-half
the hysteresis value.
3.2.5 TO REVIEW/MODIFY CONTROL SETTINGS
Repeatedly depress the SCROLL key. If any control outputs exist, the OUT LED (OUT 1/1, OUT2/1, etc.) for the first existing
control will flash along with its current control setpoint in the order shown below. Note that CC (for chart changing) will also
appear in the sequence when the SCROLL key is repeatedly depressed.
OUT 1/1 LED flashes Display shows Pen 1/Control setpoint
value
OUT 2/1 LED flashes Display shows Pen 2/Control setpoint
value
If Control Changes are allowed/enabled, use the UP/DOWN keys to change the setting. All control settings are defaulted to 0
and are adjustable from -9999 to 9999 (assuming no decimal positions).
If Control Changes are disabled, the settings cannot be changed, only viewed.
16
3.3 ALARM SETTINGS
There are two possible alarm set point values for each of the two possible inputs/pens. They will be displayed only if the alarm
options are present and configured. The types of alarms and the ability to make alarm set point changes, is defined during
configuration. See Section 4 to select the types of alarms and to allow/disable alarm changes.
TO REVIEW/MODIFY ALARM SETTINGS
Repeatedly depress the SCROLL key. If any alarms exist, the alarm LED (ALRM 1/1, ALRM 1/2, etc.) for the first existing
alarm will flash along with its current alarm set point in the order shown below. Note that CC (for chart changing) will also
appear in the sequence when the SCROLL key is repeatedly depressed.
OUT 1/1 LED flashesDisplay shows Pen 1/Alarm 1 setpoint value
OUT 1/2 LED flashesDisplay shows Pen 1/Alarm 2 setpoint value
OUT 2/1 LED flashesDisplay shows Pen 2/Alarm 1 setpoint value
OUT 2/2 LED flashesDisplay shows Pen 2/Alarm 2 setpoint value
If Alarm Changes are allowed/enabled, use the UP/DOWN keys to change the setting. All alarm settings are defaulted to 0
and are adjustable from -9999 to 9999 (assuming no decimal positions).
If Alarm Changes are disabled, the settings cannot be changed, only viewed.
3.4 HIGH/LOW LIMITS
High or Low Limits are latching alarms. Once an alarm is engaged, it will remain active until BOTH of the following occur:
1) The alarm condition no longer exists (i.e. for a high limit the process value has fallen below the alarm
setpoint), and,
2) The alarm condition is acknowledged by depressing the red reset button to right of the display, on the platen.
The button will reset any limit alarms that can be reset.
If power is cycled and the alarm condition no longer exists, the corresponding limit will be reset.
Section 4 - Recorder Setup, Test, and Calibration
Because the MODE switch protects the configuration as well as the calibration of the recorder, "calibration seal" labels are
provided to cover up the switch, if desired, to secure the configuration and calibration, as well as record the date of the
calibration. The label looks like this:
MODE
CAL
DATE
/
/
If necessary, remove the label or "seal" to access the MODE switch.
The instrument has two basic "modes" of operation. The Run mode (as addressed in Section 3) is the normal operating
mode. The other basic mode is the Program/Test/Calibration mode, which is used only for setup, troubleshooting, and
calibration. The Program/Test/Calibration mode, accessed by having the MODE switch in the PROG/TEST/CAL position, is
further divided into the three respective modes of Program, Test, and Calibration. Each of these modes is divided into
sections corresponding to a portion of the programming parameters, or individual test or calibration functions.
The availability of various options (i.e. alarms, communications, etc.), as defined by the model number shown by the recorder
on power-up, will determine the selections offered in the Program, Test, and Cal mode. For example, if no alarm options exist,
then the alarm types do not need to be configured.
Located on the back of the access panel (inside the recorder) is a Short Form Programming Card that can be used as a
reference for selecting all program parameters.
17
4.1 HARDWARE SELECTIONS - INPUT JUMPER POSITIONS
Hardware jumpers JU1 and JU2 are used to select the input type for Pen 1 and Pen 2 respectively. The jumper positions are
shown on the main wiring label on the recorder as well as on the Short Form Programming Card. See below:
JU1 and JU2 Positions - JU1 is located between wiring terminals TB2 and TB3 on the edge of the main board. JU2 is located
between wiring terminals TB3 and TB4 on the same board.
RTD and Millivolt 5 VDC Milliamp Thermocouple
4.2 RECORDER PROGRAMMING
The recorder setup programming can only be accomplished when the MODE slide switch is placed in the PROG/TEST/CAL
position. This switch is located to the left of the display. The Program mode is used to select: chart rotation speed, input
types/ranges, display scaling, and display options, chart scaling, and relay operation.
In the Program/Test/Calibration mode, the keys will function as follows:
SCROLLWhen a mode or section designation is displayed, SCROLL steps to the next mode or section.
When a parameter code is displayed, SCROLL will display the corresponding parameter value.
When a parameter value setting is displayed, SCROLL will display the next parameter code.
DOWN ARROW When a mode or section designation is displayed, DOWN will enter that mode or section.
When a parameter code is displayed, DOWN will display the next parameter code.
When a parameter setting is displayed, the setting will be decremented or changed, unless it is at its limit.
UP ARROWWhen a mode designation is displayed, the UP key will have no effect, as the instrument is at the initial level.
Use the MODE switch to return to normal operation.
When a section designation is displayed, the UP key will revert to the mode designation.
When a parameter code is displayed, UP will revert back to the section designation.
When a parameter setting is displayed, the setting will be incremented or changed, unless it is at its limit.
To enter the Program/Test/Cal mode, position the MODE switch accordingly. The unit will display Prog. Subsequent
depressions of the SCROLL key will cause the unit to display tESt, and then CAL, and back to Prog.
NOTE: When the MODE switch is placed in the PROG/TEST/CAL position, all output LEDs will be turned off and all
relays will be deenergized.
To enter the Program mode, press the DOWN arrow key when Prog is displayed.
The display will show PEn1 (Pen 1 parameters). Subsequent depressions of the SCROLL key will show PEn2 (Pen 2
parameters, if Pen 2 exists), CHAr (Chart operation), CP (Comms parameters, if optional communications is installed) and
then back to PEn1.
To enter the desired section of the Program mode, press the DOWN arrow key when the desired section is displayed.
Use the keys as defined previously to enter modes and sections, move around, and modify parameter settings. The parameters, their definitions, and range of adjustment, are as follows:

Section 5 Recorder Calibration Mode - CAL
As covered in Section 4, the "calibration seal" may need to be removed to access the MODE switch to gain access to the
calibration section. The MODE switch must be positioned to the PROG/TEST/CAL position.
CAUTION: DO NOT ATTEMPT ANY CALIBRATIONS WITHOUT THE PROPER TEST EQUIPMENT THAT MEETS OR
EXCEEDS THE SPECIFICATIONS LISTED.
The Calibration mode provides for the calibration of all the input types for each input as well as the calibration of each pen to
the chart.
The Input Calibration can be performed for
ONLY the Input Type selected in the Program Mode Input Selection code InPS. See below:
ONLY the Input Type selected bt the hardware jumpers JU1 and/or JU2 AND
5.1 INPUT CALIBRATION - inP
EQUIPMENT REQUIRED:
Input source with accuracy better than±0.05% of reading.
Thermoucouple: 1 J type
1 mercury thermometer ±.25ºF or equivalent
Allow 30 minutes of warm up time for the instrument with the T/C connected before
proceeding with calibration
DC:0 to 50mV or
0 to 5V or
0 to 20mA
RTD:Decade resistance box with .01% resolution or equivalent.
PROCEDURE:
Position the input conditioning jumpers (JU1 for Pen 1 and JU2 for Pen 2) for the proper input (T/C, RTD, mV, mA or V). Be
sure that the Input Selection parameter InPS in Program Mode has been set correctly.
To enter the Calibration mode, depress SCROLL until CAL appears on the display. Press DOWN to enter the Calibration
mode. Depressing SCROLL will display the following Calibration sections: inP and Chrt. inP is the input calibration section
and Chrt is the Chart calibration section. Press DOWN to enter the desired section when it is displayed.
The Input Calibration section is divided into four sections: PEn, rAng, rEF, and SCAn. PEn selects the pen/input to be
calibrated, rAng selec!ts the input type (T/C, RTD, etc.) to be calibrated, rEF defines the source value to be applied, and
SCAn performs the actual calibration.
A 50mV Input calibration must be performed before the Cold Junction Compensation Calibration can be performed.
With PEn displayed, depress the SCROLL key to display the pen/input selected. Use the UP or DOWN keys to select 1 or 2,
then depress the SCROLL key and rAng should be displayed.
With rAng displayed, depress the SCROLL key to show the range code of the input type to be calibrated. The range codes
are shown below. Use the UP or DOWN keys to select the range to be calibrated:
0=None, means no calibration will be performed.
1=50 millivolts for all millivolt and thermocouple ranges.
2=5 volts for all volt ranges.
22
3=Milliamp for all milliamp ranges.
4=RTD for all RTD ranges.
5=Cold Junction Compensation for all T/C ranges.
After selecting the proper range code, depress the SCROLL key and rEF should be displayed.
With rEF displayed, depress the SCROLL key to display the value for the source to be connected. Connect the input source
set for this value to the selected input terminals. After connecting the source, depress the SCROLL key and SCAn should be
displayed. When rAng selected is 5, connect the J type thermocouple to the input terminals. Position the "HOT" junction
outside the enclosure with the mercury thermometer position along side. Using the UP or DOWN keys, make the display
match the reading seen on the mercury thermometer.
With SCAn displayed, depress the SCROLL key. The display will count up in seconds, denoting that it is proceeding with the
calibration. When the calibration is complete, the display will show PEn.
With PEn displayed, depress the SCROLL key to select another pen, or UP to return to inP.
If something fails in the process, FAIL will be displayed. Depress any key to return to the inP display.
The reference values needed to calibrate each input type are as follows:
This Cal section calibrates the pens to the chart, and is divided into two additional sections: PEn and ArC. PEn calibrates the
pen spans to the chart. ArC provides a capability to make the pens sweep the chart to facilitate mechanical adjustments of
pen arms.
PEN SPAN CALIBRATION
With Chrt in the display, press DOWN to enter the Chart calibration section and PEn will be displayed. Depressing the
SCROLL key will toggle between PEn and ArC. With PEn in the display, press DOWN to enter the Pen Span calibration
section. Each pen will home (move downscale), and the display will blank (this could take as long as 20 seconds). The
display will show P1Lo.
With P1Lo displayed, Pen 1 will be positioned at the low end of the chart. Use UP or DOWN to position Pen 1, the red pen, on
the inner ring of the chart. Press SCROLL when done.
The display will now show P1Hi and the red pen will go to the outer ring of the chart. Again, use UP or DOWN to adjust the
pen. Press SCROLL when done.
If Pen 2 is included, the same process must be repeated for Pen 2, the green pen. After P2Hi is completed, depressing
SCROLL will return to PEn.
If Pen 2 is not included, press SCROLL twice to skip P2Lo and P2Hi calibration, and return to PEn.

PEN ARC MECHANICAL ADJUSTMENTS
Important Note:
Pen arc adjustments have been done at the factory and should not need to be done in the field, unless the pen arm
adjustments (mechanical) have been compromised. (This can happen if the pens are forcibly moved.)
Adjustments can be made at the bottom or top of span. In either position, the arm "length" can be adjusted by moving the pen
blade toward or away from the pivot point, but the pen tip should also line up with the inner or outer ring of the chart. The
latter is referred to as "position". Only the red pen can be adjusted to draw the correct arc. It is not mechanically possible for
the green pen to draw the correct arc if the red pen is adjusted to do so.
With Chrt in the display, press DOWN to enter the Chart calibration section and PEn will be displayed.
With PEn displayed, depressing the SCROLL key will toggle between PEn and ArC. With ArC in the display, press DOWN to
enter the Pen Arc adjustment section. During arc calibration/adjustment, ArC will remain in the display. The pens will move to
the home position and the red pen will then draw an arc upscale.
If the pen is upscale, pressing the DOWN key will cause the selected pen to move downscale. If it is already downscale, the
DOWN key will cause the chart to advance. If the pen is downscale, pressing the UP key will cause it to move upscale. If it is
already upscale, the UP key will cause the chart to advance. Adjust the red pen's "length" and "position" on the inner/outer
ring as needed. Repeat this sequence until the red pen is properly adjusted.
When finished with the red pen, press SCROLL to adjust the green pen. For the green pen, the "length" should be adjusted
so that it almost touches the red pen when they pass each other. Adjust the "position" to align with the inner/outer ring. When
finished with the green pen, press SCROLL to exit. P1Lo will be displayed, as the Pen Span calibration must now be done.

Section 6 Model Number Changes
When adding options to the recorder in the field, it is necessary to change the model number contained within the memory of
the recorder.
The model number is displayed during the power up sequence. The first 8 digits of the model number are displayed in two 4
digit steps. The first displayed value will be the prefix 5, the first pen option, second pen option, and pen 1 output (the first 4
digits of the model number). The next display will show the pen 2 output, communications, case, and voltage options present
on the recorder.
To change the model number, set the MODE switch to the PROG/TEST/CAL position, and power down and power up the
recorder. After the software revision is displayed while the pen(s) go to the home position, the first 4 digits of the model
number will be displayed. Use UP or DOWN to change the number. Press SCROLL and the next 4 digits of the model
number will be shown. Again use UP or DOWN to change the number. Make sure the model number is correct for the
hardware options present.
When complete, depress SCROLL. Refer to section 4.2 to make any programming changes required by the change in
hardware options.
