Switching examples

Ensure that suitable interference suppression is
provided when connecting the latch drive and exter-
nal output contactors (RC elements or rapid recov-
ery diodes directly via inductors).

6.2. Connecting
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, con-
tactor 6-K45. The wiring should be subsequently
supplemented in accordance with the diagram be-
low.

Overriding the light curtain

The light curtain is overridden if Override delay
latch
(Überbrückungsverzögerung ) and Option 2 inputs
receive a negative edge. The Override delay
(Überbrückungsverzögerung) and Option 2 inputs
can be connected in parallel with the Latch_In
(Riegel_In) input if required.
