4.9.2.1 ZMR operating mode manual
In "manual" ZMR operating mode, the retriggering of the contactor must be
acknowledged beforehand. The necessity of an acknowledgement is indi-
cated by the ACKR bit field (input byte 1, Bit 7). The bit value "1" indicates
that an overload with manual ZMR function was detected. Bit value "0" indi-
cates that no overload is present and that an acknowledgement has already
taken place. The "manual" ZMR operating mode is activated by sending the
value "0" in bit field ZMR M/A (output byte 0, Bit 3).
ï¿«
In the event of a phase unbalance and activated ZMR function,
the value of the thermal motor image is raised from 100 % to
110 % after a trip.
The switched off contactor's availability to reclose is restored
when the value falls below 100 %.
