Limit Switch Adjustment - Bauer CROSS5 Serie Manual De Instalación Y Mantenimiento

3.5 Limit switch adjustment

- Manually position the door wing completely open and
fasten the limit switch brackets [L] onto the rack so that
the lever limit switch exceeds the bracket's length by
approximately 2/3. Repeat the operation with door wing
completely closed.
- After having performed a certain number of operations,
adjust the position of the limit switch bracket [L] so that
the gate will stop about 20 mm before the opening and
closing stops.
Note: (Only for CROSS5EH-7EH) the limit switch kit is optional
and it is used to stop the gate before the opening and closing
stops. When limit switch is present, slow down is carried out at
maximum power to overcome possible friction.

3.6 Operation by encoder
The CROSS5EH-7EH does not require limit switches because
it has an encoder. Mechanical stops must necessarily be in-
stalled. The gate decelerates automatically in proximity of the
mechanical stops.
Attention: upon reaching the opening or closing limit stop, the
gate performs a brief disengaging maneuver (moving reversal)
to facilitate the manual release of the geared motor.

3.7 CROSS7EHTC installation (only CROSS5EH-7EH)
Release the gearmotor (see OPERATING INSTRUCTIONS).
Remove the pinion [14]. Fix the pinion supporting plate to the
gearmotor. Insert the pinion as illustrated in the diagram. Manu-
ally pass the chain between the pinions. Fix the cover plate.
Attention: fitting the chain the drive direction of the gearmotor
is inverted.
3.8 Chain installation
- Move the gate into the open position and fix brackets [G]
onto the gate as illustrated in the figure.

- Connect the chain, which was previously assembled on
the gearmotor, to tie rod [H] and fix it to bracket [G].
- Fix bracket [G] on the opposite side of the gate. Connect
the chain to the tie rod [H] and fix it to bracket [G] (cut the
excess chain).
Note: make sure that the distance between the pinion
centre [Y] and tie rod [H] is correct when the gate is fully
open and closed.
- Secure the gearmotor with the nuts [F].
- Tighten the chain with the tie rod [H]. - Slightly lubricate the chain and pinion after assembly.
