It is recommended that the FMS output signal be simulated with current
transmitter, making it very easy to locate the fault.

Fault 371 The monitor output of the FMS constantly monitors the current flowing
(terminals 47 and 49), (only if set to "Internal Load"). A current must flow at
all times if the monitor output is configured to "Internal Load".
If the output is not used, the terminals must be short-circuited.

Short-circuit terminals directly

___________________________________________________________________
If the current can no longer flow entirely via the negative input (terminal 49)
because of an external earth connection, this fault will occur even though the
output current is correct.
