9. CURTAIN LOCKING & SETTING MOTOR LIMIT SWITCHES
Before you operate the door electrically you may want to
operate the door slowly using the manual override provided
to ensure that the door will not catch on any protrusions as
it travels up and down.
Your garage door is manufactured with the curtain height to suit
the length of guide supplied. The door will not lock down properly
if the curtain is either too tall or too short. (If too tall remove
slat(s) – if too short notify supplier). For best results the top of
the curtain should be as near as possible in line with the centre of
the axle.
Both limits require setting along with a final adjustment of the
locking mechanism.
We recommend the use of the manual override to set the limits
and to make final adjustments as you will have far greater control
of the door as it travels up and down. To set the limits remove the
cap covering the white/yellow limit switches, fully press in both
switches (they will lock into position) and then proceed as follows.
N.B. Incorrect setting of the limits
risks damage to the motor and
curtain.
Closed / down limit setting and locking section
adjustment:
The locking block position must be checked before proceeding –
i)
wind door down with override handle until the curtain is
touching the floor but stop just before the top of the curtain
closes against the ‘shut’ face.
ii) Lower the locking blocks so that they are positioned
approximately 2mm above the blocks fitted to the curtain
when the curtain is in the fully closed position. Ensure that
both screws in each block are tightened so that the block will
not be lifted.
iii) Continue to wind door down until the curtain is tight against
‘shut face’ but not over tight (the extrusions will deform if you
force the top slat too hard into the lintel)
iv) set the motor closed/down limit by releasing limit switch.
Open/Top Limit Setting:
i)
Wind the door with the hand crank to open / up position and
stop (50mm of curtain should still
be in guide. Stops should be min.
10mm below guide rollers)
ii)
press and release the open/up limit
switch
N.B. Always replace the yellow limit
switch cover cap once limits are set.

After a door has been installed, during normal operation, the the
door will settle causing the fully open and fully closed positions to
move slightly from the original positions.
N.B.
To prevent damage to the
motor make sure the door is
stopped by reaching the limit
switch. Do not allow stops to
come into contact with guide
rollers.
