Magnets for limit switch
Install the magnet as shown in Fig.8. 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. Fit the magnet bracket to the gate 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 (1 inch) away from the magnetic limit switch. If it is
too far away, the switch will fail to work. Moving the gate electrically, adjust the position of the
magnet until the positions of the opening and closing meet the requirements.
Important Note: There are two reed switches inside the magnetic limit switch: one is
upper and the other is lower. Please note the two magnet brackets (fixed plate) are
