Transformer error
Cause:
Transformer connection error
Remediation:
Check if the channels are deactivated without a connected current measure-
ment transformer.
Make sure that the current measurement transformer plug is firmly seated.
Make sure that the connections (lines) of the current measurement trans-
former, where the error occurred, are firmly seated.
Pull out the plug of the current measurement transformer.
Use a continuity tester to test lines k and l for the connected current meas-
urement transformer, where the error occurred, for continuity.
If an electrically conductive connection does not exist, replace the current
measurement transformer.
If there is an electrically conductive connection, replace the RCM 202-AB.
After completing the work, reconnect the plug of the current measurement
transformer to the RCM 202-AB.
Make sure that the plug is firmly seated.
