Table 8.2 Diagnostic Messages (Continued)
OI/ACA592/EC–EN Rev. B
Possible Cause(s)
[Related Condition]
Ground loops present or shorted
sensor cable.
[PROCESS]
The analog output for the Primary
Variable is beyond its high / low
scaling limit and no longer
represents the true applied process.
The Analog Output (4 to 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]
Sensor temperature is below range.
[PROCESS]
8 Troubleshooting and Diagnostics
Corrective Action
Verify sensor wiring.
Verify sensor wiring is not shorted to other wiring or
metal surfaces.
Verify terminal blocks and other connections are
free of any liquids, oils, scale or corrosion.
If a sensor extension is being used, verify
connections are dry and free of corrosion.
Verify configuration settings are correct.
Verify internal sensor connections are free of any
liquids, oils, scale or corrosion.
Adjust the working range if possible.
If a temperature sensor is connected, activate a
Run TC Recognition. If recognition fails, check the
temp sensor wiring. Ignore or mask this warning if
Manual TC is required.
(Maskable message)
Verify sensor wiring.
Verify configuration related to temperature sensor
and temperature compensation.
