According to DIN EN81-20 it must be possible to open the door by hand with a force that
does not exceed 300 N. In order to support this requirement by means of the door control
unit it is possible to parameterize a "
Service menu "
The default value for the release time is 0 seconds (deactivated). The "Idle torque CLOSE"
parameter must be set so that the door can be pushed at least 5 mm out of the closed
position with a force of less than 300 N when the DOOR CLOSE command is pending.
If the release time is set to a value greater than zero (for example 10 ms), the following
function is active:
Normal mode:
If at an active command "DOOR CLOSE" the door is pressed by at least 5 mm from the
CLOSED position in the opening direction, the motor is deenergized for the duration of the
release time. If the door is moved during the deenergized state in the opening direction, the
release time is extended by the duration of the movement.
After the release time has expired and a "DOOR CLOSE" command is active, the door
closes with the values set in the parameters "

motor is deenergized again for the duration of the release time.
After the CLOSE position is reached or a "DOOR OPEN" command is given, the door closes
with the normal drive profile again in the next closing movement and thus with the values set
in the "
Initial mode:
If at an active command "DOOR CLOSE" the door is pressed by at least 5 mm from the
blocking position in the opening direction, the motor is deenergized for the duration of the
release time.
After the release time has expired, the door closes with the parameterized "

In order to allow release with a force below 300 N, the door and closing mechanisms have
to be designed and set correspondingly.
The parameter "Idle torque (power) CLOSE" has to be set, depending on the closing
mechanism, counterweight and door friction, so that manual opening of the door (release)
at an active "DOOR CLOSE" command is possible with a force lower than 300 N.
The emergency release function is only active in the CLOSED position at an active "DOOR
CLOSE" command.
