Adjustment ranges
The value of the parameter must be selected so that the door moves across the entire door
width in the closing direction if a close command is present. Inadequate force can lead to an
obstruction of the door.
The closing force can be set for the geared motors within the adjustment ranges of the
parameters (see Section Profiles and adjustment ranges (Page 296)).
A warning appears on the digital display of the terminal module if the set closing force of
150 N is exceeded. The stated values refer to doors opening to one side. A load cell in the
middle of centrally opening doors would show only half the value.
Risk of injury and material damage due to excessive closing force of the door
When the closing force is set, it is imperative that any effective closing weight is taken into
account.
The desired closing force must be reduced by 10 N for each 1 kg of counterweight. This
affects the:
• Closing force CLOSE
• Closing force cutter distance CLOSE
• Nudge force CLOSE
Example: Closing weight = 4 kg
Desired static force limit CLOSE = 150 N
The counterweight of 4 kg corresponds to a force of 40 N. The force limit then has to be
adjusted to 150 N – 40 N = 110 N.
The factory settings are preconfigured for the following counterweights:
● 4 kg for the M2 motor
● 6 kg for the M3, MDG180 DIN EN 45545-2 and M5 motors
● 8 kg for M4 motors
This means that the resulting static closing forces are limited to 110 N, 90 N and 70 N
respectively.
