7.2 Functions of the inputs and outputs

The user can evaluate outputs 63A-64A of the motor operator as well as outputs 63B-64B of
the electronic module so that it is easy to localize the fault in the electronic module or motor
operator: outputs 63A-64A only show the state of the motor operator, whereby outputs 63B-
64B show the state of both the electronic module and the motor operator.
A high level of operational readiness can be ensured in the event of a fault:
● If outputs 63B-64B of the electronic module are closed and outputs 63A-64A of the motor
operator are open, the user can bypass the electronic module and actuate remote control
for transfer switching via inputs 312 to 317 on the motor operator.
● If outputs 63A-64A of the motor operator are closed, manual transfer switching with the
supplied handle is possible in the event of an emergency.
Outputs 71, 72, 74 (only relevant for the network / generator application)
These outputs enable starting and stopping of the generator:
● If source I is not available, contact 71 is closed with 72, and at the same time 74 is open.
● If source I is available, contact 71 is closed with 74, and 72 remains open.
Output RJ45
This output is used for connecting the additionally available 3KC9823-0 display. This is
described in more detail in the section titled Display (3KC8 only) (Page 164).
