UDC 3300 Controller Product Manual

4/00

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.

Unable to write to non-volatile memory.
Anytime you change a parameter and it is
not accepted, you will see EE FAIL.

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.

FAILSAFE
or
FAILSF2
(Loop 2)

This error message shows whenever the
controller goes into a failsafe mode of
operation. This will happen if:

• RAM test failed
• Configuration test failed
• Calibration test failed
• Burnout configured for none and

the input failed.

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.

Two consecutive failures of input 1
integration. i.e., cannot make analog to
digital conversion. This will happen if:

• Upscale or Downscale burnout is

selected

• Input not configured correctly

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.

Two consecutive failures of input 2
integration. i.e., cannot make analog to
digital conversion.

Same as INP1FAIL above.

Two consecutive failures of input 3
integration, i.e., cannot make analog to
digital conversion.

Same as INP1FAIL above.

Position Proportional input slidewire failure

1. Check motor slidewire connections.

2. Recalibrate the slidewire motor position. see the

calibration section (Section 8.3).

Position Proportional or 3 Position Step
Control with Motor Position Indication,
Auto Cal never performed.

1. Calibrate the controller for Position Proportional

output. Refer to Subsection 8.3 – Position
Proportional and 3 Position Step Output
Calibration.

• PV low limit is > PV high limit
• SP low limit is > SP high limit
• Output low limit > Output high limit

1. Check the configuration for each item and

reconfigure if necessary.
