What could be the reasons for Sepam relay with MET1482 module displaying RTD fault and **** for temperature readings.
There could be below possibilities
1-Shield for RTD is connected at the monitored end (motor for instance). The RTD shield must be connected
at the MET1482 module only.
2-The RTD sensor is not configured correctly. The RTD sensor is set in SFT2841 by clicking the ... box next to
the MET1482 enable section under the Sepam configuration tab (screenshot attached is from a Sepam M20 relay).
3-The RTD's are two wires with a shield and not three wires with a shield. While this is not supported it may be made
to work by jumpering terminals 1 and 2 for each RTD.
