Table 9-12 Procedure #7—Troubleshooting current proportional output failure symptoms
Step
What to do
How to do it or where to find the data
1
Be sure the recorder is configured for
current output.
Refer to Section 3 - Configuration. Make sure
OUT ALG selection = CURRENT.
2
Check the field wiring.
Refer to Section 2 - Installation.
3
Be sure all the recorder and control
related data is correct.
Refer to Section 3 - Configuration.
Check the tuning, algorithm, and control data.
4
Check the output.
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.
5
Recalibrate the current proportional
output.
Refer to Section 8 - Output Calibration.
6
Replace the control output printed circuit
board.
Refer to the instructions included with the
replacement part.
Table 9-13 Procedure #8—Troubleshooting position proportional output failure
symptoms
Step
What to do
How to do it or where to find the data
1
Be sure the recorder is configured for
position proportional output.
Refer to Section 3 - Configuration. Make sure
OUT ALG selection = POSITN.
2
Check the field wiring.
Refer to Section 2 - Installation.
3
Check the output.
Put the recorder into manual mode and adjust the
output manually to drive the motor from 0% to
100%.
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.
Refer to Section 8 - Output Calibration for motor
slidewire calibration. Refer to the motor
instructions.
5
Check the output voltage to the slidewire.
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.
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.
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.
7
Check the control relay jumper position.
Refer to Section 3 - Configuration.
8
Replace the control output printed circuit
board.
Refer to the instructions included with the
replacement part.
9
Recalibrate the position proportional
output.
Refer to Section 8 - Output Calibration.
