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