4.4 Motor-driven daytime release
To activate the motor-driven daytime release, the link must be severed as shown,
e.g. with diagonal cutter.
In the as-delivered condition, the motor-driven daytime release
is not
possible.
Once the power supply has been restored, the controller B-54900-01-2-8 reboots.
The permanent release function can then be used.
The lock now remains in the release position for as long as a signal is applied at control input I1 or I2
in addition to the power supply (+24 V DC, terminal G2 and V2). Once the signal has dropped out,
the lock moves back to the initial position.
If a voltage loss occurs during the motor-driven daytime release, the points described under 4.3
apply.
If the control signal is still applied at I1 or I2 once the power supply has been restored, the motor-
driven daytime release is automatically reactivated.
In combination with the emergency power backup B-54903-23-3-9, the signal must on the other
hand be applied again once the power supply has been restored.
(only active if the link has been severed)
Disconnect the controller from the power supply before you sever the link!
ATTENTION
When the link is severed, the approval for use at fire and smoke protection doors is invalidated!
