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)
