→ Power failure This parameter determines the behaviour of the door controller
after a power failure.
→ Battery operation In case of sufficient battery capacity, the door goes on func-
tioning as before the power failure. However, the door is oper-
ated with reduced acceleration to preserve the battery capaci-
ty. In case of low battery capacity, the emergency operation
configured with
Parameter → Battery emergency operation
is
executed (see above).
▪ Battery operation is only possible with a lead battery.
▪ Battery operation is generally not possible with STM21.
▪ With a RED door an emergency opening is triggered after
approx. 12 seconds. When mains voltage is back, a re-
dundancy test is executed.
→ Emergency operation X After a power failure the emergency operation configured with
Parameter → Battery emergency operation
is immediately exe-
cuted (see above).
Battery This parameter indicates if a battery is connected and what
type of battery it is.
▪ If a battery is connected for the first time, it is normally
automatically identified.
Without Battery X No battery connected.
Lead-acid battery A lead battery is connected.
▪ The STM 21 requires an additional circuit board with
NiCd A NiCd-Akku is connected.
DOOR SYSTEM
A-dimension 0 Door width: 0..59'999 mm
This value is only compulsory for folding doors.
G-dimension 0 Door height: 0..59'999 mm
Door leaf This parameter is necessary for a correct calculation of the
door width and of other parameters depending on it.
