5.1.3 External earth-fault monitoring (with summation current transformer)
Response
Here you can set the response of SIMOCODE pro to an external earth fault:
See also "Tables of responses of SIMOCODE pro" in Chapter "Important
information".
Fig. 5-2: "Earth-fault Monitoring" function block
Table 5-2: "External earth-fault monitoring" response
1) Further delay of the summation current transformer delay
If the response is set to "Signaling" the "External earth fault" event will be
generated in the case of an earth fault.
If the response is set to "Warning", the "Warning external earth fault" event
will be generated in the case of an earth fault.
Activity
Unless deactivated, this function is always active, independent of whether
the motor is running or not (operating state "ON").
