Product Description 1.1

1.1.1 GENERAL

The unit is a circular chart recording instrument capable of measuring, recording, and
controlling up to two process variables from a variety of inputs. Applications include
temperature (degrees F and C), pressure, relative humidity, pH level, electrical measurement,
flow and others.

Instrument capabilities such as recording, controlling functions, alarm settings, and other
parameters are selected from the order matrix and are factory implemented.

The process input for each pen is configured, at the factory, per order matrix model selection
and directly connects to either thermocouple, RTD, mVDC, VDC, or mADC inputs. Most
changes to input type are easily accomplished in the field. However, an input change from
thermocouple to RTD on units with Recorder PWA's at revisions before Rev D should be done
only after consulting with factory. Inputs are factory calibrated and will require re-calibration if
changed in any way. Thermocouple cold junction compensation is performed automatically by
the instrument.

The instrument can operate with either 115VAC or 230VAC line voltage at 50 or 60Hz. The
voltage and frequency are selected when ordering. The 230VAC line voltage option includes
soldered jumpers to allow the electronics to be configured to 115VAC line voltage when
necessary. The chart drive is not switchable, and must be changed whenever the line
voltage or frequency is changed.

PAGE 5

The instrument is housed in a durable enclosure suitable for panel or surface mounting.

1.1.2 RECORDING

The unit incorporates a 10 inch circular chart. One box of standard charts is provided with
each instrument. Charts are available in a wide selection of zero based, non-zero based,
reverse, and dual scale ranges. The instrument can be provided with one or two pens. Pen
1 is red and Pen 2 is green. Pens are of the disposable fiber-tip type. Changes in pens, as
well as charts, are quickly and easily accomplished.

Displays & Status Indicators

Setpoint is selected/observed using a 3 or 4 - digit pushbutton thumbwheel potentiometer.
Two LED indicators are provided :

INDICATOR COLOR DESCRIPTION
OUT1 Red Output 1 status
OUT2 Yellow Output 2 status

PAGE 6

1.1.3 SETPOINT/STATUS INDICATORS

Each recording controller is provided with either a remote or local setpoint capability. If a
local setpoint is desired, the following selections are available:

• Three digit positive only thumbwheel

• Three digit positive and negative thumbwheel

• Four digit positive only thumbwheel

The thumbwheel provided in the upper right corner is for Pen 1 and the thumbwheel provided
in the lower right corner is for Pen 2. The status indicators provided depend upon the specific
pen function, e.g. alarm only, high limit, on-off controller relay, on-off controller SSR driver,
time proportioning relay, time proportioning SSR driver or 4 to 20mA. A detail of the status
indicators is shown in Figure 1-2. Status indication is provided for Pen 1 Output 1, Pen 1

Installation & Wiring 2.1

At shipment from the factory the instrument has been configured to accept input(s) as
specified. AC power input is as specified in the model number; 115VAC or 230VAC. Verify
the AC power input provided with the instrument prior to proceeding with installation.

Read these instructions carefully before proceeding with installation and operation. Electrical
code requirements and safety standards should be observed. Installation should be per­formed by qualified personnel.

Installation of the Instrument includes:
* Unpacking
* Location
* Mounting
* Preparation for Wiring
* Wiring Connections

Unpacking 2.2

Remove the instrument from the carton and inspect it for any damage due to shipment. If any
damage is noticed due to transit, report and file a claim with the carrier. Write the model
number and serial number of the instrument on the front cover of this Operation Manual for
future reference when corresponding with the factory.

Location 2.3

Locate the instrument away from excessive moisture, oil, dust, and vibration. Do not subject
the instrument to operating temperatures outside of 0 to 55° C. (0 to 131°F)

Mounting 2.4

Figure 2-1 shows installation view and physical dimensions for the panel mounted instrument.
The panel that the instrument will be mounted in must provide rigid support for the approxi-

mately 20 pound Instrument. Adjacent Recorders or Recording Controllers may be mounted
within a minimum of 2 inches horizontally and 3 inches vertically, providing that proper panel
support is supplied.

PANEL MOUNTING HARDWARE REQUIRED: ( Not provided with instrument)

(4) 9/32" x 2" bolts w/nuts
(4) appropriate lockwashers

The location of the instrument is important and should be located in an area void of excessive
moisture, vibration, oil, and dust. The instrument should also be located in an ambient
temperature of 0 to 55° C (32 to 131° F).

For panel mounting, cut the panel hole to the dimensions shown in Figure 2-1 (page 9). If the
rear of the panel is accessible for wiring after installation, mount the instrument in the panel by
opening the hinged cover and fastening the instrument to the panel through the mounting
holes located in the case flange. If the rear of the panel is not accessible, the instrument must
be wired first. In this case, see wiring instructions.

For surface mounting, install the brackets ordered separately to the sides of the instrument
case and mount to the surface.

Preparation for Wiring 2.5

This section is divided into two parts: Wiring Guidelines, and Sensor Placement. Please
review this completely before proceeding with wiring of instrument.

The wiring guidelines contained in the following paragraphs must be followed to
ensure the best possible performance of the instrument. Please review this section
carefully before proceeding.

2.5.1 WIRING GUIDELINES

2.5.1.1 AC POWER WIRING

Clean AC power is required to ensure a proper installation. To be classified "clean" the
following must be met:

Earth Ground
Earth ground must be attached to the instrument's chassis. To verify that it is earth ground
being attached, make a resistance check from instrument chassis to the nearest metal water
pipe or proven earth ground. This reading should not exceed 1000 ohms.

2.5.1.2 WIRE ISOLATION

3 conduit openings, EC1, EC2, and EC3 are provided so wiring can be divided into separated
catagories.

* Analog input or output (i.e. thermocouple, RTD, VDC, mVDC or mADC)
* SPDT Relay or SSR driver outputs
* AC power

The only wires that should be run together are those of the same category. Each of these
must be isolated from each other .

2.5.2 SENSOR PLACEMENT (Thermocouple or RTD)

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

Two wire RTD's should be used only for 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.

Wiring Connections 2.6

All wiring connections are typically made to the instrument with it installed. Terminal connec­tions should be made via terminal blocks with captive wire clamps, two 12 gauge wires
maximum.

Use the wiring connections, Figure 2-3 (page 12), for planning all wiring installation. The
layout in Figure 2-3 shows the general location and orientation of all terminal blocks. Termi­nal blocks are designated TB1 thru TB6. Figure 2-3 shows details for the various possible
input connections. Paragraph 2.6.2 provides descriptive detail for AC power connections.
Paragraph 2.6.3 details all input connections, and paragraph 2.6.4 provides wiring connection
details for all outputs.

2.6.1 ELECTRICAL CONDUIT OPENINGS

Figure 2-1 shows the location of all electrical conduit openings that are provided on the
instruments. These openings are labeled EC1 thru EC3. It is recommended that wiring enter
the instrument through the conduit openings provided as follows:
EC1 - AC power
EC2 - Analog input and mAdc outputs
EC3 - SPDT relay or SSR driver outputs

Following these recommendations will help ensure proper operation .
Unused conduit openings should be sealed if exposed to the environment.

2.6.2 AC POWER WIRING CONNECTIONS

Avoid electrical shock. AC power wiring must not be connected at the source
distribution panel until all wiring connection procedures are completed.

Consult the model code and the wiring label for the appropriate line voltage for the unit.

Instruments specified with 230VAC power input, as specified in model number, are
provided with a soldered jumper which allows configuration back to 115VAC. Verify
soldered jumper configuration before proceeding with AC power wiring (see Fig.
4-4). Also ensure correct AC chart drive motor is installed (line voltage is stamped
on motor.

PAGE 11

CONNECT AC WIRING AS FOLLOWS:

1. Run AC power cable through the EC1 conduit opening as shown in Figure 2-1 (page 9).

2. Connect AC hot and neutral to terminals 1 and 2 respectively of TB1 as shown in
Figure 2-2 (below).

3. Connect Earth Ground to the instrument ground screw as shown in Figure 2-3 (page 12).

4. If Event Pen option is present, connect the 115VAC power through the EC1 conduit
opening as shown in Figure 2-1 (page 9) and as labeled in Figure 2-3A (page 12).

regardless of which line voltage supply used for instrument supply, event pen
operating voltage is 115 VAC only.

The event pen marks the circular chart on the outside edge of the paper. The pen
movement is short but a distinct difference can be seen between the On and Off cycles of
the pen. Typical event pen usage is for indication of an alarm condition.

Terminal connections are made using TB3 of the respective recorder board for the First
Output Relay or SSR Driver and TB2 of the respective recorder board for the Second Output
Relay or SSR Driver. Terminal 1 is N.O., terminal 2 is Common, and terminal 3 is N.C. for
both TB2 and TB3 for Relay Outputs.

The Normally Open ( N.O. ) contacts of the relays should be used for control outputs to
ensure that the outputs are OFF when power is removed from the instrument. Control outputs
are jumper configurable for reverse or direct action for heating and cooling applications
respectively.

Terminal 1 is positive and terminal 2 is negative for both TB2 and TB3 for SSR Driver Out­puts. Terminal 3 of TB2 and TB3 is not used with SSR Driver Outputs. (ie. loads that are
smaller than 5 watts in power consumption).

For high impedence loads (i.e. Neon lamp) it may be necessary to remove snubber network
(R68 thru R72 on PWA 046-155-XX) otherwise output will be continuously activated even

Tuning and Alarm Adjustments 3.1

The Recording Controller can be ordered providing proportional control. This type of control
is provided with Proportional (P), Integral (I, auto reset), and Derivative (D, rate) control
responses. Partlow defines the PID parameters as follows:

P(Proportional) Proportional Band
I(Intergral) Automatic Reset
D(Derivative) Rate

The above PID parameters are jumper selectable.
Manual Reset is provided for use in lieu of, or in conjuction with Automatic Reset, and a Cycle

Time selection is provided for use in Time Proportioning control applications. All are jumper
selectable. These parameters are discussed in the following paragraphs.

3.1.1 PROPORTIONAL BAND

The Proportional Band adjustment is made in terms of percentage. This parameter defines
the band over which the control output will function. Proportional Band Adjustment is jumper
selectable and is factory set at 5%. Refer to Appendix A-2 (page 31).

This control response defines the controller Gain. The Gain is defined as the amount of
change in output for a given change in input. The higher the controller gain, the larger the
control output will be. The proportional Band in % is the mathematical inverse of the Gain, i.e.
Gain = 1/Proportional Band %. The larger the proportional band is, the smaller the Gain. The
smaller the proportional band the larger the Gain. For proper control of the process, the
controller gain must be set to match the gain of the process, i.e. High Process Gain requires
Low Controller Gain (Wide Proportional Band), and Low Process Gain requires High Control­ler Gain (Narrow Proportional Band).

3.1.2 AUTOMATIC RESET

Automatic Reset or Integral action response adjustments are made in terms of repeats per
minute. This can be defined as the number of times a change in the control output, due to the
proportional action, will be repeated in one minute. Automatic Reset is jumper selectable and
is factory set at 0 repeats per minute. Refer to Appendix A-2 (page 31). Before using
Automatic Reset it is advisable to first zero Manual Reset.

3.1.3 MANUAL RESET

The Manual Reset parameter is adjusted in terms of span (%). This adjustment will shift the
proportional band by ± the Manual Reset value. This allows for compensation of the offset
between the process value and the setpoint, after the process has settled out. Manual Reset
will provide ± 50% of the span and is factory set near midpoint (0%). This is adjustable at
the setstation.

3.1.4 RATE

Rate or Derivative action is adjusted in terms of minutes. The Rate time is defined as the
time the output from a PD (proportional band + derivative) controller will lead the output from
a P (proportional band ) only controller when both experience the same input change. Rate
action is applied to the process input, not the setpoint. Rate is a dynamic parameter and is
adjusted to the time constants and lags in the process. Rate should affect the control output
only when the process itself changes. Rate is jumper selectable and is factory set at 0
minutes. Refer to Appendix A-2 (page 31).

3.1.5 CYCLE TIME

Controllers used in Time Proportioning applications require a Cycle Time adjustment in
addition to the PID responses. Cycle Time can be defined as the time duration or period
of oscillation of the relay or SSR driver output. Cycle Time is selectable in terms of
seconds and is factory set at 10 seconds. Refer to Appendix A-2 (page 31).

3.1.6 DIRECT/REVERSE CONTROL ACTION

Each control output is jumper selectable for direct or reverse action. Direct acting propor­tional control provides an increasing output as the process value increases. Reverse
acting control provides a decreasing output as the process value increases. In On/Off
control, Reverse action turns the output "ON" when the process goes below setpoint.
Direct action turns the output "OFF" when the process goes below setpoint. The current
output, first relay output, and LED output are jumper selectable and are factory selected
for reverse action. The second output is jumper selectable and must be configured in the
field. Refer to Appendix A-2 (page 31).

3.1.7 ON - OFF CONTROL

On - Off operation can be field "jumper configured" for either or both Output 1 or Ouput 2.
Instruments with 1st and 2nd output configuration can be field "jumper configured" for
Direct/Direct, Direct/Reverse, Reverse/Direct, or Reverse/Reverse control applications.
Refer to Appendix A-2 (Page 31) for jumper selection.

PAGE 19

Alarm Adjustments 3.2

THE ALARM OUTPUT MUST BE CONFIGURED IN THE FIELD. Refer to Figure A-2 (page 31) and Table on

botton of page 32.

3.2.1 PROCESS ALARM

The Process Alarm is adjustable from 0 to 100% of span. This type of alarm remains fixed
and does not track the process control setpoint. Clockwise adjustment of pot on front
platen (see Fig 1-2) increases the actuation point. There are two ways to adjust the
Process Alarm Actuation point. One method is via a simulator input (ie. millivolt source,
decade box or current generator), a second method is via the Process Input.

Simulator Input Source (Use decade box for RTD controllers)

1. Remove power if applied to instrument being adjusted for alarm actuation.

2. Disconnect input from board being set up for alarm functions.

3. connect up appropriate input signal to terminal block 4 (TB4).

4. Apply power to instrument.

5. Adjust input source to align pen with the desired alarm actuation point.

6. Turn the front panel second output adjustment until alarm is actuated. Clockwise
rotation will increase the actuation point.

7. Once alarm setting is set, return instrument to normal operation, ie remove power,
re-connect original source, etc.

8. Re-supply power and test if possible process alarm in actual operation.
Process Input

1. Supply the process temperature to the recorder controller equal to the desired alarm
actuation point.

2. Adjust the alarm setting for actuation at this point. Clockwise rotation increases the
actuation point.

The Deviation Alarm is adjustable ± 25% of span of setpoint and tracks the primary setpoint
(retains relationship with the setpoint regardless of the latter's position). The second output
must be configured in the field. Refer to Appendix A-2 (Page 31). Counterclockwise adjust­ment increases the actuation point, with the potentiometer midpoint actuating the alarm at

3.2.3 DEVIATION BAND ALARM

The Deviation Band Alarm is adjustable ± 25% of span from setpoint and tracks the primary
setpoint similar to the Deviation Alarm. The second output must be configured in the field.
Refer to Appendix A-2 (Page 31). Counterclockwise adjustment of Output 2 or Alarm potenti­ometer narrows the band width. Clockwise adjustment of Output 2 or Alarm potentiometer
widens the band width.

Service 4.1

4.1.1 CHANGING CHARTS

Chart changes may be done while in the normal operating mode.

1. Pens will be active and the chart will continue rotating.

2. Open the instrument door, unscrew the chart center hub, and swing the namestrip
arm out of the way.

3. Gently lift the pens up and carefully remove the old chart. Do not apply too much
upward force on the pen arms or they may bend out of shape or be damaged.

4. Install new chart. Lift pens up out of the way. Do not bend pen arms. Make sure
that the current time on chart is lined up at the "current time setting" mark on the chart
platen.

5. Place namestrip arm over chart and tighten chart center hub.

6. Close the instrument door and place the instrument in the desired mode.

CAUTION: Chart hub pin (Optional ) is sharp to perforate chart. Use caution in
installing chart so fingers are not injured.

4.1.2 CHANGING PENS

Open the instrument door. Refer to Figure 4-1 for pen changing procedure. This
procedure is provided on a label on the instrument chart platen.

Calibration 4.2

Do not attempt any of these calibrations without the proper test equipment with specifications equal to
or better than those listed.

4.2.1 The following pertains to thermocouple inputs only.

When simulating thermocouple inputs for calibration, the millivolt values must be
compensated for the temperature of the cold junction, that is, the temperature at the terminal
block on the Recorder board. The simplest and most accurate method of doing this is to use
a compensated millivolt source or thermocouple simulator which does this automatically. In
this case, no special or additional steps are required and the Calibration Check and
Calibration Procedures can be followed as stated.

If a compensated source or thermocouple simulator is not available, a simple millivolt source
can be used, but the millivolt values must be corrected to compensate for the ambient
temperature at the terminal block.

Due to the sensitivity of the cold junction compensation sensor, you may experience problems
performing calibration and obtaining repeatability when a millivolt source is used rather than a
thermocouple simulator or compensated millivolt source. The unit's compensation sensor can
be eliminated to facilitate calibration and provide repeatibility when a simple millivolt source is
used. This may induce error, due to possible error in the compensation sensor (1 degree C
max.), but this is probably no more than that due to the thermocouple used.

Refer to Figure 4-2 (page 27) for the location of the revision level of the Recorder bare
boards, which is etched on the board.

PAGE 23

Rev C and newer Recorder boards include a two-position jumper JU11, which selects normal
compensation or a fixed cold junction temperature of 32°F (0°C). With this feature, the unit
can be calibrated using the millivolt values directly form the thermocouple tables. After the
calibration or check is complete, move JU11 back to the "normal" position.

On older boards, Rev A or Rev B, the compensation sensor can be eliminated, but not as
easily, and the millivolt values must be adjusted. The following procedure simulates a cold
junction temperature of 0° F (-17.8°C), which is not the assumption used in the tables, and
corrects the table value accordingly.

1. Temporarily connect a jumper (wire with eze-hooks on each end) from R38 to R48, as
shown in Figure 4-2 (page 27).

2. Connect the millivolt source to the unit and calibrate per standard instructions using
corrected millivolt values.

The corrected values are obtained by subtracting the millivolt value, for 0° F to the table
value for the desired temperature for the proper thermocouple. In equation form:

CORRMV = TBLMV - (TBLZF)
Where: CORRMV is the corrected millivolt value.

TBLMV is the millivolt value from the table.

TBLZF is the millivolt value from the table for 0° F (-17.8° C).
(Continued on next page)

PAGE 24

(Continued from page 23)
Example: For range 0 to 300F Type J
From the tables: 0 F = -0.885 mV

300 F = 7.947 mV

For 0 F: CORRMV = -0.885 - (-0.885) = 0.000 mV
For 300 F: CORRMV = 7.947 - (-0.885) = 8.832 mV

Example: For range 0 to 300C Type K
From the tables: 0 F = -0.692 mV

0 C = 0.000 mV
300 C = 12.207 mV

For 0 C: CORRMV = 0.000 - (-0.692) = 0.692 mV
For 300 C: CORRMV = 12.207 - (-0.692) = 12.899 mV

3. After the calibration or check is complete, disconnect the jumper that was connected to
R38 and R48.

4.2.2 CALIBRATION CHECK

To check the accuracy of the recorder:

1. With the
the Recorder PWA board (top board) and the red lead of the digital voltmeter to testpoint
TP7 on the Recorder PWA board.

2. The voltage measured should be about equal to the process value divided by the span,
multiplied by 10.

3. Set the setpoint to 50% of span. (Only required if instrument is not a recorder only, no
outputs)

4. Clip the red lead of the voltmeter to TP1 on the Controller PWA board (bottom board).

5. The voltage measured should equal negative 2.500 VDC, ± 0.003 VDC.

6. If any of the above volt readings are incorrect, recalibration is necessary.

process value known, clip the black lead of a digital voltmeter to testpoint TPC on

TP7 = (Process Value ÷ Span) x 10

4.2.3 CALIBRATION PROCEDURES

The following procedure provides complete calibration of input, pen and setpoint.
THE FOLLOWING ADJUSTMENTS APPLY TO THE RECORDER PWA.

1. Clip black lead of digital voltmeter to TPC.

2. Clip red lead to TP6.

3. Locate R102 and adjust for -5.000 ± 0.001VDC.

4. Move red lead to TP4.

5. Adjust input device for minimum of span, making sure to compensate for ambient
temperature if required for thermocouple inputs.

6. Locate R103 and adjust for 0.000 ± 0.003 VDC.

7. Move red lead to TP7.

8. Locate R104 or R103 depending on the range. Adjusting R104 may not affect some
ranges such as RTD or Linear. If this is the case, R103 must be adjusted. The process
value is limited by circuitry to a range of 0 to 10.25 volts. Zero adjustment must be
accomplished as follows : Turn the adjustment screw on R104 or R103 (whichever
applies) clockwise until the voltage observed
increases. After the observed voltage increase, turn the adjustment screw counter­ clockwise until the voltage observed is 0.000 ± 0.001VDC.

9. Locate R100 and adjust so that the pen is at minimum of span.

10. Adjust input device for maximum of span, making sure to compensate for ambient
temperature if required for thermocouple inputs.

11. With red lead on TP7, locate R101 and adjust for 10.000 ± 0.001 VDC.

12. Locate R105 (red lead still on TP7) and adjust so that the pen is at maximum of
span.

13. Adjust the input device for 10% of span, making sure to compensate for ambient
temperature if required for thermocouple inputs.

PAGE 25

14. Referring to step 8, adjust the appropriate potentiometer, R104 or R103, for 1.000
± 0.001VDC.

15. Locate R100 and adjust so that the pen is 10% of span.

16. Adjust input device for maximum of span, making sure to compensate for ambient
temperature if required for thermocouple inputs.

17. With red lead on TP7, locate R101 and adjust for 10.000 ± 0.001VDC.

18. Locate R105 and adjust so that the pen is at maximum of span.

19. Repeat steps 14 through 19 until no further adjustments are required.

20. It may be necessary to go through the procedure again, starting at step 7, to make
sure zero and span do not shift.

21. Remove the jumper if it was added or restore JU11 to the "normal" position if it was
moved for checking or calibration.

PAGE 26

(Continued on next page)
(Continued from page 25)

IF THE INSTRUMENT HAS A CONTROL PWA, THE FOLLOWING ADJUSTMENTS ARE
MADE ON THE CONTROL PWA.

1. Set the thumbwheel station to minimum of span.

2. Move red lead to TP1.

3. Locate R100. The setpoint signal is limited by circuitry to a range of -5.000VDC to

0.000VDC. Zero and span adjustments must be accomplished as follows : Turn the
adjustment screw on R100 clockwise until the magnitude of the voltage observed
increases. After the observed voltage increases, turn the adjustment on screw R100
counter-clockwise until the voltage observed is 0.000 ± 0.001 VDC.

4. Set the thumbwheel station for maximum of span.

5. Locate R101 and turn the adjustment screw counterclockwise until the voltage
observed decreases. After the observed voltage decreases, turn the adjustment screw
clockwise until the voltage observed is -5.000 ± 0.001VDC.

6. Set the thumbwheel station to 10% of span.

7. Adjust R100, if necessary, for -0.500 ± 0.001VDC.

8. Set the thumbwheel station to 90% of span.

9. Adjust R101, if necessary, for -4.500 ± 0.001VDC.

10. Repeat steps 6 through 9 until satisfactory results are obtained.
