Internal ground-fault monitoring when using a current measuring module or a 1st
generation current / voltage measuring module
Response
Here you can set how SIMOCODE pro will respond to an internal ground fault:
See also "Tables of responses of SIMOCODE pro" in Chapter Important information
(Page 7).

0 to 25.5 s (default: 0.5 s)
You can activate internal ground-fault monitoring by parameterization. It covers two different
operating conditions:
● Normal operation up to 2 x I
s
. The actual operating current must be smaller than twice the
current setting I
s
. Residual currents of > 30 % of the current setting I
s
are detected.
● Start-up or overload operation to 2 x I
s
. The actual operating current is greater than 2x the
current setting I
s
. Residual currents of > 15 % of the effective motor current will be
detected.
Trip level activity, warning level
Unless deactivated, this function is always active, independent of whether the motor is
running or not (operating state "ON").
