Troubleshooting Procedures
Table 9-12 Procedure #7—Troubleshooting current proportional output failure symptoms
Step
1 Be sure the recorder is configured for
current output.
2 Check the field wiring.
3 Be sure all the recorder and control
related data is correct.
4 Check the output.
5 Recalibrate the current proportional
output.
6 Replace the control output printed circuit
board.
Table 9-13 Procedure #8—Troubleshooting position proportional output failure
Step
1 Be sure the recorder is configured for
position proportional output.
2 Check the field wiring.
3 Check the output.
4 Check whether the motor drives in both
directions. If it does, go to step 5. If the
motor drives in one direction only, check
the slidewire. If the motor does not drive
in either direction, check the motor.
5 Check the output voltage to the slidewire.
6 Be sure that the output relays are
actuating properly. If they are not, check
the field wiring, then go to step 4. If they
are, go to step 7.
7 Check the control relay jumper position.
8 Replace the control output printed circuit
board.
9 Recalibrate the position proportional
output.

What to do
How to do it or where to find the data
Refer to Section 3 - Configuration. Make sure
OUT ALG selection = CURRENT.
Refer to Section 2 - Installation.
Refer to Section 3 - Configuration.
Check the tuning, algorithm, and control data.
Put the recorder into Manual Mode and
raise/lower the output manually from 0% to 100%
(4–20 mA). Use a milliammeter at connection J1
on the control output printed circuit board.
Refer to Section 8 - Output Calibration.
Refer to the instructions included with the
replacement part.
How to do it or where to find the data
Refer to Section 3 - Configuration. Make sure
OUT ALG selection = POSITN.
Refer to Section 2 - Installation.
Put the recorder into manual mode and adjust the
output manually to drive the motor from 0% to
100%.
Refer to Section 8 - Output Calibration for motor
slidewire calibration. Refer to the motor
instructions.
Put the voltmeter across the slidewire terminals
at connector J2 on the control output printed
circuit board and check that the slidewire voltage
varies with the motor position.
Put the recorder into manual mode and adjust the
output manually above and below the present
value. Listen for the click of the relays. One relay
should click when the output is adjusted higher,
and the other should click when the output is
adjusted lower than the present value. Observe
OUT 1 and 2 indicators on the front display.
Refer to Section 3 - Configuration.
Refer to the instructions included with the
replacement part.
Refer to Section 8 - Output Calibration.
