Maintenance
Attention
The door system must be regularly checked by an expert to ensure that it is in safe working order. The door
manufacturer stipulates the frequency of maintenance and checks according to national regulations and the
frequency of use.
Counterweight (applies to sectional doors with spring compensation or a counterweight):
The counterweight/spring tension must be checked. The sectional door should be counterweighted in every position. Note the
door's operating instructions.
The following checks must be performed on the drive:
1. Fastenings:
All fastening screws, including the screws to secure the torque bracket, must be checked to ensure they are in good condition and
fastened securely.
2nd Safety limit switches:
The functionality and switch-off point of the safety limit switches S1F, S2F and S3F must be checked. Follow the relevant assembly
and operating instructions for the door control unit. The safety limit switches must be checked for continuity as per the connection
diagram.
Re S1F / OPEN (applies to cam-operated limit switching)
Open to the upper limit position. Using the emergency manual operation function, keep opening up to the point where no damage
occurs. The safety switch S1F must be checked as per the connection diagram. There must be no continuity.
Re S2F / CLOSE (applies to cam-operated limit switching)
Close to the lower limit position. Using the emergency manual operation function continue closing until the load-bearing medium
(e. g., cables or chains) for suspending takes the complete weight of the door sections. It must be ensured that the cables do not
fall from the cable drum. The safety switch S2F must be checked as per the connection diagram. There must be no continuity.
Re S3F (applies to HK and LK drives)
Before inspecting the safety switch S3F, the door system must be disconnected from the mains.
Insert the crank handle (HK) in the motor shaft and turn through at least one revolution and hold the position or pull the light chain
(LK) and keep it taut.
The safety switch S3F must be checked as per the connection diagram. There must be no continuity.
3. Gears:
The gears are lubricated for life and maintenance-free.
4. Toothed belt
1. Check that the toothed belt (1) has sufficient preliminary tension.
2. Carry out a visual check of the toothed belt (1) along the complete travel distance of the door. The toothed belt (1) must show
no signs of wear.
