The electronic controller also allows the configuration of additional closing and open-

ing delays. If no configuration is selected, only the natural closing and opening time

of the switching device is active. Configuration is done via a 6-pole DIP switch S2

on the electronics assembly (matrix, see Chapter "Configuring the controller", p. 42).

The auxiliary switches are mounted on the side of the operating mechanism box and

are not wired. The wiring is carried out on the customer's premises using screw ter-

minals.

(Applies only to vacuum contactors with closing latching)

When the vacuum contactor is closed, the mechanical closing latching is activated.

The solenoid actuator is held and automatically separated from the supply voltage

once the latching position is reached.

Switching in the de-energised holding mode (supply voltage circuit A1/A2) is carried

out automatically via the electronic controller.
