Emergency release
Description of function
An emergency release can only be actuated if the following conditions are met:
• Neither a DOOR OPEN nor a DOOR CLOSE command is present,
• The service buttons are not pressed.
• The terminal module, SIDOOR SERVICE TOOL and SIDOOR USER SOFTWARE are not in the
• The "Idle torque without door commands" parameter is set to "OFF".
• The door has come to a complete stop.
The door drive is only torque-free if these conditions are fulfilled.
With pending command DOOR CLOSE or if the parameter "Idle torque without door command"
has the value "ON", the emergency release is only possible when the parameter "Idle torque
CLOSE" is adjusted and a "release time" has been parameterized (see the following function
description).
The door control unit can only support an emergency rescue. The closing mechanism of the
door must be designed so that an emergency rescue is possible.
According to DIN EN81-20, the force required to open the door must be less than 300 N.
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 "Release time" between 0 and 60 seconds via the service menu
"General setup > Special parameters > Release time" .
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 s), 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.
