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

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 Read 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 whether the tests
pass or fail, then run through the STATUS codes a
second time to see if the error cleared.
1. Make sure the range and actuation are configured
properly.
2. Check the input source.
3. Restore the factory calibration.
4. Field calibrate.
1. Make sure the actuation is configured correctly.
See Section 3 - Configuration.
2. Make sure the input is correct and that it has not
burned-out (opened).
3. Check for gross over-ranging with a multimeter.
4. Restore factory calibration.
Same as INP1RNG above.
Same as INP1FAIL above.
1. Check the configuration for each item and
reconfigure if necessary.
