4.5 Motor-driven daytime release
To activate the motor-driven daytime release, the seal and the board behind it must be
pierced, e.g. with a mini screwdriver, as shown in fig. 5. In the as-delivered condition,
the motor-driven daytime release cannot be activated!
Once the lock has been rebooted, the function can be used.
The latchbolt now remains retracted for as long as a signal is applied in addition to the power supply
(+ 24 V DC Pin 13 and GND Pin 14) at the control input (pin 9/green) and is only projected again after the
signal drops out.
The lock is in standby mode during the motor-driven daytime release (see 1).
If a voltage loss occurs during the motor-driven daytime release, the points described under 4.6 apply.
If a control signal continues to be applied after the power supply is restored, the latchbolt is retracted again
immediately, even if the lock has in the meantime been moved to the "locked position", e.g. via the locking
cylinder.
If the lock cannot unlock when driven by the motor, e.g. due to excessive load on the door leaf, it switches
to overload protection. If the control signal continues to be active, the lock tries to retract the latchbolt three
times in 20-second intervals and signals this event with a red LED in the lower part of the latchbolt hole
(see fig. 1).
If the lock still cannot unlock after these 3 attempts, it ignores all incoming control signals.
(only active when the seal is broken)

Before piercing, the lock must be disconnected from the
power supply!
ATTENTION
When the seal is broken, the permit for use at fire and smoke protection doors
is invalidated!
