9.5 Background Tests

Introduction
Background tests
Lower
Display
EE FAIL
Unable to write to non-volatile memory.
Anytime you change a parameter and it is
not accepted, you will see EE FAIL.
FAILSAFE
This error message shows whenever the
or controller goes into a failsafe mode of
FAILSF2 operation. This will happen if:
(Loop 2)
• RAM test failed
• Configuration test failed
• Calibration test failed
• Burnout configured for none and
INP1FAIL Two consecutive failures of input 1
integration. i.e., cannot make analog to
digital conversion. This will happen if:
• Upscale or Downscale burnout is
• Input not configured correctly
INP2FAIL
Two consecutive failures of input 2
integration. i.e., cannot make analog to
digital conversion.
INP3FAIL Two consecutive failures of input 3
integration, i.e., cannot make analog to
digital conversion.
SW FAIL Position Proportional input slidewire failure 1. Check motor slidewire connections.
CAL MTR Position Proportional or 3 Position Step
Control with Motor Position Indication,
Auto Cal never performed.
CONF ERR
• PV low limit is > PV high limit
• SP low limit is > SP high limit
• Output low limit > Output high limit

The UDC 3300 performs on-going background tests to verify data and
memory integrity. If there is a malfunction, an error message will be
displayed (blinking) in the lower display.
In the case of more than one simultaneous malfunction, only the one with
the highest priority will appear in the lower display. Table 9-6 lists these
background tests, the reason for their failure, and how to correct the
problem.

Background Tests
How to Correct the Problem
1. Check the accuracy of the parameter and re-enter.
2. Try to change something in configuration.
3. Run through STATUS tests to re-write to
EEPROM.
1. Run through STATUS check to determine the
reason for the failure.
2. Press the SET UP key until STATUS appears in
the lower display.
3. Press the FUNCTION key to see what tests
pass or fail, then run through the STATUS codes a
second time to see if the error cleared.
Correct according to the recommendations given
in Table 9-5.
1. Make sure the actuation is configured correctly.
See Section 3 - Configuration.
2. Make sure the input is correct.
3. Check for gross over-ranging.
4. Replace factory calibration. See Section 7.6.
5. Replace the cold junction assembly.
Same as INP1FAIL above.
Same as INP1FAIL above.
2. Recalibrate the slidewire motor position. see the
calibration section (Section 8.3).
1. Calibrate the controller for Position Proportional
output. Refer to Subsection 8.3 – Position
Proportional and 3 Position Step Output
Calibration.
1. Check the configuration for each item and
reconfigure if necessary.
