Possible Cause(s)
[Related Condition]
The analog output for the Primary
Variable is beyond its high scaling
limit and no longer represents the
true applied process. The Analog
Output (4-20 mA) is saturated to the
configured Saturation Limit High /
Low.
[PROCESS]
The device is in Manual TC mode
and not measuring process
temperature.
[STATUS]
Problem with the sensor, improper
calibration, incorrect configuration
of user defined positive/negative
sensor offset limit.
[SENSOR]
Problem with the sensor, improper
calibration, incorrect configuration
of user defined positive/negative
sensor offset limit.

8 Troubleshooting and Diagnostics
Corrective Action
Adjust the working range if possible.
If a temperature sensor is connected, activate a
Run TC Recognition routine. If recognition fails,
check the temperature sensor wiring. Ignore or
mask this warning if Manual TC is required.
Clean sensor and repeat a buffer and / or process
calibration.
If sensor is functioning properly, order a spare
sensor to replace the existing sensor when failure
occurs.
Replace existing sensor if sensor is not functioning
properly.
Verify sensor wiring is free of nicks, cuts, breaks,
shorts and/or open connections. If wiring is
damaged, replace wiring and / or sensor and
recalibrate.
Clean sensor and repeat a buffer and/or process
calibration.
If sensor is functioning properly, order a spare
sensor to replace the existing sensor when failure
occurs.
Replace existing sensor if sensor is not functioning
properly.
Verify sensor wiring is free of nicks, cuts, breaks,
shorts and / or open connections.
If wiring is damaged, replace wiring and/or sensor
and recalibrate.
