The space between rack and gear is about 1mm.
Bring another rack element near to the previous one. Move the gate manually and weld
the three pawls as the first rack, thus proceeding until the gate is fully covered.
When the rack has been installed, to ensure it meshes correctly with the gear.
If necessary, assemble the spacer between the rack and pawl to synchronise the teeth
of the two rack elements and keep racks in a straight line. See Fig.7
Screw the nylon rack
Manually move the gate to its closing position.
Lay the first piece of rack on the gear and mark the drilling point on the gate, drill a hole
and screw the bolt.
Move the gate manually, checking if the rack is resting on the gear, and repeat the

Magnets for limit switch
Install the magnet as shown in Fig.8 and Fig.9. The magnet and limit switch are used to control
the position of the gate. When the magnet is installed, release the gear clutch and push the
sliding gate manually to pre-determine the position. Weld or fit the magnet bracket to the rack
and then tighten the gear clutch. The lower bracket is for open position and higher bracket is
for close position. Finally adjust the magnet to the proper position by moving the gate with
the motor. The magnet should be 10-15mm away from the magnetic limit switch. If it is too
far away, the switch will fail to work. Adjust the position of the magnets until the positions of the
opening and closing meet the requirement.
Important Note: Please note the two magnet brackets (fixed plate) are different: one is
higher and another is lower. Verify and if necessary exchange the two brackets position.
Also if necessary exchange the limit switch wires CL (close) and OP (open).
Another
common problem is there are two reed switches inside the magnetic limit switch: one is
