8 Troubleshooting and Diagnostics
Corrective Action
Verify sensor wiring.
Verify configuration related to temperature sensor
and temperature compensation.
(Maskable message)
Check temperature sensor connections.
If a temperature sensor is not connected, switch
temperature compensation to Manual mode.
If the problem persists, contact factory.
(Maskable message)
Adjust the working range if possible.
(Maskable message)
Verify sensor wiring.
Verify configuration setting for the sensor.
(Maskable message)
Verify sensor tip is clean.
Remove any foreign material.
