Terminals A1/A2 and optionally E1/E2 of the electronic controller
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.
The configuration is delivered ex works according to the option ordered.
For adjustments to the secondary voltage, the customer can reset the configuration
via a 6-pole DIP switch S2 on the electronic assembly. (matrix, see chapter “Config-
uration of supply voltage
of the electronic controller”, p. 45).
Auxiliary switch
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 spring bal-
ancer or screw terminals.
Mechanical closing
latching
(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.
