The door manufacturer stipulates the frequency of maintenance and checks according to national
regulations and the frequency of use.
Counterweight(only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.
2.Safetylimitswitches:
The functionality and switch-o point of the safety limit switches S1F, S2F and S3F must be checked. Follow the relevant as-
sembly and operating instructions for the door control unit. The safety limit switches must be checked as per the connecting
diagram for continuity.
Re S1F / OPEN (applies to A80 - A280)
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 connecting diagram. There must be no continuity.
Re S2F / CLOSE (applies to A80 - A280)
Close to the lower limit position. Using the emergency manual operation function, keep closing until, in the case of sectional
doors and vertical lift gates, the load-bearing medium (e.g., cables and chains) for suspending takes the complete weight of
the door sections or, in the case of roller doors, the door slats are completely closed. It must be ensured that the cables do not
fall from the cable drum. The safety switch S2F must be checked as per the connecting diagram. There must be no continuity.
Re S3F (applies to all 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 or pull the light chain LK and keep it taut.
The safety switch S3F must be checked as per the connecting diagram. There must be no continuity.
