Glidermatic-GRD-Setting-Door-Travel-Limits

The door travel is determined by rotation of cams in
the drive unit. The cams are driven by a gear
mechanism and activate a limit switch at the desired
position.
• The inner cam determines the closed position.
• The outer cam determines the open position
1. To Adjust
• Set door to manual operation using the
manual release lever (refer image 4).4
• Remove the cam gear cover on the drive unit
to gain access to the internal cams
• Loosen cam gear screws (x3)
2. Closing – Inner Cam
• To set the closing position, manually lower the
door to the required closed position observing
the direction of rotation of the inner most cam
• Rotate the inner cam in the direction observed
until it activates the inner limit switch
3. Opening – Outer Cam
• To set the opening height, manually raise the
door to the desired open position (ensure the
bottom bar is short of contacting the guide
stop), observing the direction of rotation of the
outer cam
• Rotate the outer cam in the direction observed
until it activates the outer limit switch
4. To Complete
• Tighten the cam gear screws (x3)
• Return manual release lever to normal position
• Carefully move the door in either direction until
pin engagement is noted and the unit is locked
into position
Care should be taken to ensure the lever arms on the limit
switch are not obstructed by the rotation of the gearing.
