Switching examples

Ensure that suitable interference suppression is provided
when connecting the latch drive and external output
contactors (RC elements or rapid recovery diodes directly
via inductors).

Connecting a three-phase latch solenoid

A three-phase latch motor can be simply connected by
changing the standard wiring of the cegard/Lift LX. The
following existing connections should be (starting from the
situation in Figure 11) removed: Contactor 2-4, contactor
3-5, contactor 1-K44, contactor 6-K45. The wiring should
be subsequently supplemented in accordance with the
diagram below.

Overriding the light curtain

The light curtain is overridden if the Override delay
(Überbrückungsverzögerung) and Option 2 inputs
switch from HIGH to LOW when the elevator arrives at a
floor. The Override delay (Überbrückungsverzögerung)
and Option 2 inputs can be connected parallel with the
Latch_In (Riegel_In) input if required.
