f Trip indication: Overload with tripped ZMR function
It will not be possible to switch on the soft starter until the acknowledgment
bit has been reset AND the thermal motor model in the PKE motor-protective
circuit-breaker is < 100 %. After this, a value of 0
hex
will be signalled in the
differential trip indication in bits 4 to 6 in input byte 1.
In the “manual” ZMR mode, the soft starter will be stopped when the ZMR
function has been activated and the PKE signals a request for switching off
the DS7-SWD.
NOTICE
The ZMR function can be deactivated only when the thermal
motor image falls below the 100 % mark.
