Switching Functions Of The Integrated Key-Operated Switch; Temporary Release; Permanent Unlocking; Locking - effeff 1370-20 Betriebsanleitung

3.5 Switching functions of the integrated key-operated
switch
The key-operated switch of the control module has two momentary-contact
functions which - depending on the starting status - trigger different switching
processes.
3.5.1

Temporary release

Turning momentarily in the clockwise direction from the "locked" status acti-
vates a temporary release. This means that the current flow to the locking
element is temporarily interrupted and automatically switched back on after
expiry of the set time. The door can be passed through once during this period.
On closing of the door, the release time is interrupted. (Note "Door open monito-
ring" above!)
3.5.2

Permanent unlocking

By momentary contact of the key-operated switch in the counterclockwise direc-
tion, permanent unlocking is initiated. The door can be passed through freely or
be held open.
The same function can also be initiated by an external key - for example in a
central control and monitoring panel.
Permanent unlocking can also be actuated by an external switch with perma-
nent contact, such as a timer switch.
3.5.3

Locking

By momentary contact of the switch in the clockwise direction from the "unlok-
ked" status, the door is locked, provided there is no active alarm criterion and
the door is closed.
If the door is open, the command is not accepted.
3.5.4

Alarm reset

By momentary contact counterclockwise from the "Alarm" status, an alarm is
switched off and the door is switched to permanent unlocking. The green LED
starts to flash if the alarm criterion is still active. When the cause of the alarm is
eliminated (see following chapters), the green LED stops flashing. It is now
possible to lock the door again by turning the key in the clockwise direction.
