Table 9-10 Troubleshooting Position Proportional Output Failure - Honeywell UDC 3300 Product Manual

Procedure #3
4/00
Table 9-10 explains how to troubleshoot Position Proportional Output
failure symptoms.
Table 9-10 Troubleshooting Position Proportional Output Failure
Step What to do
1 Make sure the controller 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
6.
5 Check whether the motor drives in
either direction. If the motor drives
in one direction, check the
slidewire. If the motor does not
drive in either direction, check the
motor.
6 Check the output voltage to the
slidewire.
7 Make sure the output relays are
actuating properly.
8 Recalibrate the controller.
9 Change MCU/Output board.
UDC 3300 Controller Product Manual
How to do it
Make Output Algorithm Set Up group
function prompt OUT ALG = POSITN.
Refer to Section 3 - Configuration.
Refer to Section 2 - Installation for
Position Proportional Wiring
information.
Put the controller into Manual mode
and change the output from 0 % to
100 %.
See the Position Proportional
calibration procedure in Section 8 for
motor slidewire calibration.
Refer to the motor instructions.
Should equal from 1.3 to 1.0 volts.
See wiring in the installation section
for terminal designations. The
feedback slidewire output voltage
must vary with the valve position.
Put the controller into Manual mode.
Vary the output above and below the
present value. Observe "OUT"
indicator on the operator interface.
If they are not working properly, check
the field wiring, then go to Step 5.
If they are, go to Step 8.
Refer to Section 8 - Output
Calibration.
Refer to Table 9-23.
