Optional Plug-In Modules; Back-Up Batteries Charge; Operation/ Setting Possibilities - Window Master WSC 204 Operating Manual/Technical Information

4.5. Optional plug-in modules

Module WSA 301 – alarm and fault module (master/slave)
Module WSA 302 – linking of wind/rain signal
Module WSA 303 - ventilation time module
Module WSA 304B – gab ventilation module (only WSC 204 / WSC 204MH)
Module WSA 306 – ASV module

4.6. Back-up batteries charge

Charging voltage: 27.7 -– 27.8V at 20ºC.
Charging current: is limited by the safety fuse 0,63A (F3).
Charging voltage disconnected in the event of a short-circuit .
Replace the emergency back-up batteries at least every 4 years!

4.7. Operation/ Setting possibilities

Operation / LED diagnose
Pushing the reset button on the circuit board the SHE activation is reset and the actuators closes.
Setting possibilities via slide switch SW1
SW 1/1 = ON Statutory inspection activated
SW 1/1 = OFF Statutory inspection indication not activated. After activation only a coded deactivation is
possible. (Preset)
To show the activation the LED will flash 10 sec. If SW1/1 is once again set on OFF during these 10 sec., the
prioritised activation is cancelled.
After a period of 12 month the inspection indication will be activated: the yellow fault LED in the main break
glass unit will flash and the audible fault alarm will sound. The green operating LED will still flash to show that
there is no fault. An alarm signal has first priority.
SW 1/2 = ON Forwarding the alarm signal (WSA 301). After 3 min. it will stop.
SW 1/2 = OFF Forwarding the alarm signal (WSA 301) as long as the alarm is trigged. (Preset)
Setting possibilities via slide switch SW2
SW 2/1 = ON The SHE alarm trips when malfunction signal from actuator, smoke sensor, break glass
unit, max. temperature sensor or blown temperature fuse.
SW 2/1 = OFF No SHE alarm tripped when malfunction signal. Malfunction only shown on the LEDs.
(Preset)
SW 2/2 = ON The actuators only open for as long as the keypad is pressed (dead man control)
SW 2/2 = OF The actuators will open if the keypad is activated (selfhold). (Preset)
