Function

After applying the supply voltage (LED SUPPLY illuminates), the

normally open contacts remain open. If the connected sensor

is not activated (i.e. the input circuits are closed), the normally

open contacts close immediately in automatic reset (LED K2

and K3 illuminate). In the case of manual resetting, this only

occurs upon pressing and releasing the reset button.

Activation of the sensor (opening of one or both input circuits)

affects the opening of the normally open contacts (LED K2 and

K3 off).

External device monitoring (EDM)

The UE43-3MF unit can take over the external device monitor-

ing. The contactor monitoring system monitors the external

relays by way of their normally closed contacts.

Manual reset

For manual reset, a pushbutton must be connected to termi-

nals Y12 and Y13. Reset is monitored.

Automatic reset

For automatic reset, Y12 - Y14 must be linked.

Cross-circuit detection

Cross-circuit is detected on dual-channel wired systems, if

these are wired with opposing polarity.
