Table 9-12 Troubleshooting Time/Current Or Current/Time Proportional Output Failure - Honeywell UDC 3300 Product Manual

Procedure #5
4/00
Table 9-12 explains how to troubleshoot Current/Time or Time/Current
Proportional Output failure.
Table 9-12 Troubleshooting Time/Current or Current/Time Proportional
Step What to do
1 Make sure the controller is
configured for Time/Current or
Current/Time Proportional output.
2 Check the field wiring.
3 Make sure all the configurable
tuning constants, limits, and
configuration data stored in the
controller are correct. Reconfigure,
if necessary.
4 Check the relay output.
5 Check the Current Proportional
Output.
6 Recalibrate the controller.
7 Change MCU/Output board.
UDC 3300 Controller Product Manual
Output Failure
How to do it
Make Output Algorithm Set Up group
function prompt OUT ALG or OUT2
ALG = TI CUR or CUR TI.
Refer to Section 3 - Configuration.
Make sure the NO or NC contact
wiring is correct at the rear terminals.
Refer to Section 2 - Installation for
details.
Refer to Section 3 - Configuration to
check all this data and how to
reconfigure.
Put the controller into Manual mode.
Vary the output above and below the
present value. Observe OUT indicator
on the operator interface.
Put the controller into Manual mode
and change the output from 0 % to
100 % (4-20 mA). Use a DC
milliammeter at the rear terminals to
verify the output.
Refer to Section 8 - Output Calibration
for details.
Refer to Table 9-23.
