Auxiliary Output Installation
Installation Procedure
Follow the steps listed in Table 1 to add the 4-20mA Auxiliary Output
printed circuit board. The procedure assumes that the chart door is open,
the chart plate is swung out, and the power is removed.
Table 1 Adding a 4-20mA Auxiliary Output PCB
Step Action
1 Install the new card guides supplied with the kit into proper location
on the motherboard located in the left hand side of the case.
(See Figure 1 for Auxiliary Output card location)
CAUTION Install the guides with a steady pressure. Excessive
rocking will destroy its latch.
2 Slide the new Auxiliary Output board into the card guides and press in
firmly to seat the connector onto the motherboard.
3 Connect the 2-wire violet colored connector lead from the transformer
on the motherboard to the Auxiliary Output board at J4. (See Figure 1
for location)
If required, redress the leads from the Motherboard with the tie wraps
provided in the kit.
4 Locate connector J2 near the bottom of the Auxiliary Output printed
circuit board (See Figure 1 for location).
5 Run the output wires through the desired knockout.
6 Strip 1/4-inch maximum of insulation from the end of each wire.
7 Loosen the screws in terminals on the plug connector supplied in the
kit and position the plug as you would to plug it into J2 on the
Auxiliary Output board.
8 Observing the polarity, insert the wires into the appropriate screw
clamps as shown in Figure 1. Tighten the screws to secure the wires.
9 Install the wired plug into J2
10 Configure the recorder for Auxiliary Output. Refer to Tables 2 and 3.
11 Make sure that the Auxiliary Output is calibrated.
Refer to Tables 4 and 5.

AUX OUT AUXILIARY OUTPUT SELECTION provides an mA output
representing any of twelve control parameters. The display
for auxiliary Output viewing will be in engineering units for
all but output. Output will be designated in percent (%).
Other prompts affected by these selections: “4 mA VAL”
and “20mA VAL”.
DISABL NO AUXILIARY OUTPUT
IN 1 INPUT 1—This represents the configured range of input 1.
FOR EXAMPLE:
Type “J” Thermocouple (0 to 1600°F)
0°F display = 0% output
1600°F display = 100% output
IN 2 INPUT 2 represents the value of the configured range of
input 2.
PV 1 PROCESS VARIABLE 1—Represents the value of the
Process Variable for Loop 1. PV = Input 1 + Bias
DEV 1 DEVIATION 1 (PROCESS VARIABLE MINUS
SETPOINT)—Represents –100 to +100% of the selected
PV span in engineering units for Loop 1. FOR EXAMPLE:
Type “T” Thermocouple
PV range = –300 to +700°F
PV span = 1000°F
Deviation range = –1000 to +1000°F
If PV = 500°F
and SP = 650°F
then Deviation Display = –150°F
Auxiliary Output = 42.5%
NOTE: A deviation of 0°F yields an auxiliary output of
50%.
OUT 1 OUTPUT 1—Represents the displayed controller output in
percent (%) for Loop 1.
SP 1 SETPOINT 1—Represents the value of the setpoint in
units of PV for Loop 1.
PV 2 PROCESS VARIABLE 2—Represents the value of the
process variable for Loop 2.
DEV 2 DEVIATION 2 (PROCESS VARIABLE MINUS
SETPOINT)—Represents –100 to +100% of the selected
PV span for Loop 2.
See Example at DEV 1.

Output.
Use value in percent (%) for Output. (Output can be
between –5 and +105%.)
20mA VAL High Scale Value
within the range of the
selected variable to
represent 20 mA
AUXILIARY OUTPUT HIGH SCALING FACTOR—Use a
value in engineering units for: Input 1, Input 2, Process
Variable, Deviation,* and Setpoint.
Use a value in percent (%) for Output. (Output can be
between –5 and +105%.)
*When Deviation is selected, only one operating
parameter will be entered. This value represents the
deviation level that will produce 20 mA output. Zero
deviation will produce a center scale (12 mA) output. A
negative deviation equal in magnitude to the Auxiliary
Output High Value will produce a low end (4 mA) output.

Auxiliary Output Calibration
Introduction
Calibrate the recorder so that the auxiliary output provides the proper
amount of current over the desired range.
• The recorder can provide an auxiliary output current range of from
0 to 21 milliamperes and can be calibrated at 4 mA for 0% of output
and 20 mA for 100% of output or any other values between 0 and 21
mA.
Equipment needed
You will need a standard shop type milliammeter, with whatever accuracy
is required, capable of measuring 0 to 20 milliamps.
Calibrator connections
Refer to Figure 2 and wire the recorder according to the procedure given
in Table 4.
Table 4 Set Up Wiring Procedure for Auxiliary Output
Step Action
1 With the power off, door open, and the chart plate swung out; tag and disconnect field wiring
from the plug in connector J2 on the auxiliary output PCB (see Figure 2).
2 Observing polarity, connect a milliammeter’s leads to the plug for connector J2.
3 Close the chart plate; apply power and allow the recorder to warm up 15 minutes before you
calibrate.
