e) Jumper JP2
Remove the jumper (JP2) if the supply voltage to terminals G2 V2 is greater than 27 V.f).
f) Connecting terminals for control inputs I1 and I2
Control input I1
Release of active leaf (only latch trigger extends)
Control input I2
Release of active and passive leaf (latch and bolt triggers extend, vertical rods retract)
g) Connecting terminals for signal outputs at lock
Signal contact 1 ("Locked by motor" position reached)
Signal contact 1 (terminal 41 + 51) closes as soon as the shoot-bolt lock driven by the motor
has reached its initial position. During this process, the latch and deadbolt triggers are
retracted and the top/bottom locks move to the locked position. The actual automatic
locking operation of the passive leaf is only performed once the passive-leaf control lock
B 1895 has been triggered by the closing door leaf.
Signal contact 2 ("unlocked by motor" position reached)
Signal contact 2 (terminal 42 + 52) closes as soon as the shoot-bolt lock has been fully
unlocked by the motor (release of active and passive leaf).
h) Connecting terminals for latch switching contact
Latch (deadbolt) monitoring
The latch or latchbolt monitoring signal is output potential-free via the latch(bolt)
monitoring relay contact (terminal 44 + 54), as soon as the latch or latchbolt of the active
leaf lock engages in the shoot-bolt lock.
If the contact opens, the active leaf is released and can be opened, e.g. by a door drive.
