9.2 Closing time and latching action function for de-energised operation
Danger of jamming due to excessive door acceleration.
X
Do not set more than 10° latching action on the door.
The closing speed must be set using the braking force parameter to match the drive version, type of installation
and door weight.
à A power connection is necessary for setting the braking force parameter.
à See the Powerturn wiring diagram for more details on setting the braking force parameter.
X
Set the “braking force” parameter using
à
DPS (display programme switch):
8 2
01 … 14.
à
ST220 (service terminal):
Set “Movement parameters”, “Speeds”, “Braking force” using the keys or to the desired braking force (01 … 14)
and press the

key.
Setting “brake force” parameter with Powerturn F
Brake force parameter (standard value = 13).
X
Set the closing time to 5 s.
Measure the closing time:
X
Open the door up to 90° in the de-energised state.
X
Release the door and record the time until the closed position is reached.
X
Repeat the procedure if necessary until the closing time is suitable. Refer to the wiring diagram for the Power-
turn in addition.
Setting “brake force” parameter with Powerturn (without fire protection requirement)
The closing speed must be set in such a way that the requirements on low-energy function are met in the de-en-
ergised state.
X
Measure the closing time from 90° to 10° and set depending on door weight and door leaf width (refer also
to the table in the “Low-energy function” chapter in the Powerturn wiring diagram).
Adjusting latching action
When the drive reaches the switching point of the latching action switch, the braking effect is cancelled by the motor.
X
Undo the Allen screw (2).
Door falls too heavily into the lock:
X
Move the face plate (1) in the “–” direction.
Door does not fall safely into the lock:
X
Move the face plate (1) in the “+” direction.
The braking effect is interrupted earlier.
X
Tighten the Allen screw (2).
The latching action is active in the illustrated position.
The latching action position can be adapted to the circumstances at the door.
The setting of a minimum latching action is obligatory (safety function).
