DOL Starters
The DOL starter is assembled from a PKZM0 and a contactor
DILM7-DILM32. The SmartWire-Darwin module for DILM is
mounted on the contactor.
The SmartWire-Darwin module for DILM drives the contactor
so that terminals A1-A2 of the contactor must no longer be
wired. In addition two feedbacks to the SmartWire-Darwin
system take place via the SmartWire-Darwin module for
DILM.
The auxiliary contact enable
h
is connected ex-factory by
means of a bridge. If electrical locks are envisaged in the
application, the bridge can be removed and a potential-free
contact can be connected.
The auxiliary contacts integrated in the contactor can be
used, e.g. for safety interlocks.
Two feedback inputs to the programmable logic controller
are available at the three-pole terminal of connection
g
for
the potential-free contacts. If required, potential-free
auxiliary switch contacts of the protective motor switch PKZ
can be connected to these two feedback inputs.
The terminals on the SmartWire-Darwin module for DILM are
suitable for cables AWG24 to AWG16 and flexible cables
with a cross-section of 0.25 mm
2
to 1.5 mm

.
When using core end sleeves it has to be ensured that the
sleeve length is at least 8 mm.

Danger!
The auxiliary contact enable must not be used for safety-
related controller parts (

Caution!
The connection cables to the potential-free auxiliary
switches at connection X0-X1-X2
g
for the potential-free
contacts and at connection X3-X4
h
for the auxiliary
contact enable may have a maximum length of 2.8 m.
