i) Drill holes at the appropriate points to secure the rack and then tap an M8 thread. The rack should
protrude 20cm further than the pinion at both limits of gate movement to allow room for the actuators for
open and closed proximity switches.
j) Screw the distance pieces into the gate, which can also be welded in position.
k) Mount the 1 metre lengths of rack. For better results press a third length (with teeth upwards) against the
joints to produce the required distance between lengths.
l) Push the gate completely open and closed and check that it doesn’t jam. If necessary adjust the height
of the rack.
4.1.
Emergency release
Open the access panel and using the accompanying tubular “T” bar (SW22) loosen the hex head screw on
the gearbox.
Turning the bar a couple of turns anti-clockwise disengages the gears.
To re-engage the gears, turn the tee wrench clockwise as far as it will go. (see page 3).
5. Electrical
Installation
All cables should have at least the suggested cross-sections.
a) Connect the power supply.
b) The
opener closes to the left
on delivery. The right limit switch (SEZ) stops the movement.
c) If
your
gate closes to the right
swap the motor leads for „open“ and „close“ and swap the leads to the
terminals SEA and SEZ on the control board.
d) Disengage the opener.
e) Close the gate and push the holding plate with magnet along the rack until the
LED SEZ turns off. Fix the holder at this point on the rack so that the magnet
passes the housing at a distance of about 10 mm.
f) Open the gate and push the holding plate with magnet along the rack until the
LED SEA turns off. Fix the holder at this point on the rack so that the magnet
passes the housing at a distance of about 10 mm.
f) Re-engage the opener and carry out a test run with the gate. Use the push
button BT on the controller card which has serial switching OPEN-STOP-
CLOSE-STOP.
Ensure that the LED SEZ turns off when the gate is closed (not SEA)
otherwise you will have malfunctions (e.g. automatic closing becomes
automatic opening).
g) If necessary readjust the actuators for the proximity switches so that the gate
closes exactly.
h) Connect all periphery equipment.
The time required to open or close the door (running time) must be learned.
Caution:
During the learning mode the gate will move automatically several times.
Ensure nobody will enter the gate area.
Learning the running time: (see section 7.3)
Switch the power regulation on with DIP A1 and DIP A2. Choose a low setting, if required it can always be
increased (see section 7.2.).
Press LT for at least 3 seconds The LED DIAG lights.
Press LT twice. The gate closes from any position, opens completely and closes again. Press the LT button
to confirm, the running time and 10 % reserve and the power required are saved.
The opener is ready for use.
Carry on setting operating mode as described in section 7.2.
