UDC3300 Limit Controller Product Manual
How to Correct the Failure
1. Step through the rest of the STATUS
check to identify the particular failure.
Also see Table 7-6, Background tests.
RAM test passed.
1. Power cycle to see if the error clears.
Configuration checksum passed.
1. Step through STATUS tests – the
controller will recalculate the
checksum.
2. Check all configuration prompts for
accuracy. See Section 3 -
Configuration.
Working calibration checksum passed.
1. If the controller has not been field
calibrated, see Section 3 -
Configuration and change the input to
a different type. Enter it, loop through
the status tests, then return the input
type to the original one.
2. If the controller has been field
calibrated, recalibrate the controller.
Factory calibration cyclic redundancy test
passed.
1. Cycle through Status to clear the error.
2. Check the calibration. Make sure 0 and
100% are correct values.
3. Recalibrate if step 1 is unsatisfactory.
Refer to Section 6 - Input Calibration.
