Function
The inputs of the LCU-X are prepared for the dual channel
connection of AOPD sensors. These are checked for uniformity
and control the output circuit. 2 NO contacts and 1 NC contact
are available as output contacts. LEDs signal the output
conditions:
Red LED Output inactive
Green LED Output active
The LCU-X assumes the restart interlock function, so it is no
longer necessary in the machine control system. The required
command device (start button) is directly connected to the
LCU-X (NO contact).
If the start/restart interlock is already contained in the
machine, this function can be deselected on the LCU-X
(automatic reset if the sensor protection field is clear).
If the LCU-X outputs switch machine contactors, the LCU-X
provides the contactor monitoring function. This can also be
disabled, if necessary.
