Reversing starters
The reversing starters are made up of a PKZM0 and two
contactors DILM7 to DILM32. One SmartWire-Darwin
module each for DILM is mounted on both contactors.
In addition to contactor control, two feedback signals can be
sent to the SmartWire Darwin system on each SmartWire
Darwin module for DILM.
The auxiliary contact enable
h
is connected ex-factory by
means of a bridge. For the electrical interlocking of the two
contactors this bridge is removed and the auxiliary breaker
(contacts 21-22) of the other contactor is linked in as a
potential-free contact.
The auxiliary contacts integrated in the contactor can be
used, e.g. for safety interlocks.
Two feedback inputs for the programmable logic controller
are available at the three-pole terminal of connection
g
for
the potential-free contacts. If required, potential-free
auxiliary contact contacts of the protective motor switch PKZ
can be connected to these two feedback inputs (e.g. NHI-E-
…-PKZ0 standard auxiliary contact, AGM2-…-PKZ0
differential trip-indicating auxiliary contact).
h
Caution!
The SmartWire modules for DILM drive the contactors so
that the terminals A1-A2 of the contactors need no further
wiring, with the exception of the DILM12-XEV link.
j
Danger!
The auxiliary contact enable
h
must not be used for
safety-related controller parts (
