on the control unit again to open or close the leaf and reg-
ister the new position. If necessary, repeat the operation
until the leaf reaches the desired limit switch.
m
If, at the start of the installation phase, the leaf is
not correctly positioned midway along its path
when the motor is secured and the pinion is moved
along the rack, it may be necessary to reduce the
position of the limit switch on one of the two sides.
l
If the limit switch position must be dened with
greater precision, move the door back a few cen-
timetres by pressing the [Open
p
] or [Close
q
]
button on the control unit, then give the command
again for the direction to be checked.
Note If a manual learning procedure has already been com-
pleted and the entire procedure must be repeated, put
the limit switches back to their initial position by turning
the 2 adjustment knobs (B) towards the “–” mark until
the micro-switches click. Repeat the entire limit switch
adjustment procedure.
