Functions of the outputs of the motor operator
Outputs 04, 13, 14, 24
The device contains three auxiliary contacts for indicating switch positions O-I-II. These
contacts 04, 14 and 24 are auxiliary contacts for the corresponding positions and are
controlled via three microswitches.
Output 13 is used as the common control terminal for outputs 04, 14, 24.
The contacts are open in the normal state.

Outputs 63A -64A
These outputs provide permanent feedback about the product availability of the motor
operator and its switching capacity. The functional capability of the electronic module is
ignored here.
The transfer switching equipment checks product availability in the case of the following
events:
● When switching on
● When changing the switch on the motor operator from the "Manual" position to the "Auto"
position, and every 5 minutes thereafter
The internal availability test indicates whether the transfer switching equipment is ready with
regard to the control inputs. If a test shows a fault, a further test is carried out to confirm the
fault state. If the fault persists, contacts 63A-64A are opened:
● On 3KC4 and 3KC8 transfer switching equipment, the warning LED is lit on the motor
operator.
● On the 3KC8 transfer switching equipment, the "Ready" LED on the electronic module
also goes out and the fault indicator on the electronic module lights up.
● The warning LED is lit until the fault state is reset.
To reset the fault state, switch the transfer switching equipment from automatic mode to
manual operation and back again to automatic mode. Alternatively, the transfer switching
equipment can be reset on the hardware by switching off the power supply to the transfer
switching equipment for more than 3 minutes.
