4 PKE-SWD-32, interface for motor-starter combination with PKE PKE12/32
4.3 Engineering
90 SmartWire-DT module IP20 01/20 MN05006001Z-EN www.eaton.com
The auxiliary contact for the electrical enable ⑧ is connected at the factory
with a link. If electrical locks are envisaged in the application, the bridge can
be removed and a potential-free contact can be connected.
The auxiliary contact for the electrical enable ⑧ can be used on the
PKE_SWD32 for safety-related control sections (￫ Section 4.3.3, "Safety-
related applications", page 95).
The auxiliary switches integrated into the contactor can be used, for exam-
ple, as safety locking devices.
The connection terminals on the PKE-SWD-32 are suitable for AWG24 to
AWG16 cables and for flexible cables with a cross-section of 0.25 mm² to
1.5 mm².
When using ferrules it has to be ensured that the ferrule length is at least 8
mm.
A manual or electrical ON or OFF command for the contactor can also be
implemented by means of the 1-0-A switch ⑨.
The switch positions are as follows:
• 1: Contactor ON
• 0: Contactor OFF
• A: switching command via SmartWire-DT
ACHTUNG
The connection cables at terminal X3-X4 ⑧ for the "enable" aux-
iliary contact must not exceed a length of 2.8 m.
￫
Use of the 1-0-A switch for the electrical switching on or off of
the contactor is ensured only when
the PKE-SWD-32 is supplied via the SmartWire-DT connecting
cable.
