Start-up Errors
The following displays are shown when an error detected during the power-up self-test.
Option Module Problems
The “Option Slot n Error” display is shown when an error detected with the installed option
modules - where “n” is the slot number for the fault.
Replace the module in slot “n”. If this does not solve the problem, return the instrument for
servicing.
Configuration Problem
Warns if a problem has been detected with the instrument configuration. Check all settings
are correct before proceeding. If the problem persists, return the instrument for servicing.
CAUTION:
Correct the signal/wiring problem to continue normal operation. .
Input Problems
Sensor Break Detection
Whenever a problem is detected with the process variable or auxiliary input connections,
their displayed value is replaced with the word “OPEN”.
This may be the result of a failed sensor, a broken connection or an input circuit fault.
In this condition, the Control Outputs go to the pre-set power value (see Control
Configuration).
CAUTION:
Correct the signal/wiring problem to continue normal operation.
Un-Calibrated Input Detection
The instrument is fully calibrated during manufacture. If a fault occurs and the calibration
data becomes corrupted, the process input display is replaced with the word “ERROR”.
In this condition, the Control Outputs go to the pre-set power value (see Control
Configuration).
CAUTION:
Re-calibrate the input before continuing normal operation. If the problem persists,
return the instrument for servicing.
