What to do if my Honeywell ST 700 displays 'Sensor Comm Timeout'?
If your Honeywell Transmitter shows a 'Sensor Comm Timeout' error, it means there's likely no response from the sensor. First, try replacing the Electronics module. If the issue continues, then replace the Meter Body.
What to do if a critical failure has been detected in the Meter body of Honeywell ST 700?
If a critical failure has been detected in the Meter body, cycle power to the Transmitter. If the problem continues to occur, replace the Meter body.
What to do if a critical failure has been detected on the HART, DE, or FF Electronics Module of Honeywell ST 700 Transmitter?
If a critical failure is detected on the HART, DE, or FF Electronics Module, cycle power to the transmitter. If the problem continues, replace the Electronics Module.
