L200Y SLIDING GATE OPERATOR USER
’S MANUAL
15
If loop detector detects vehicles when the gate stops, the gate will remain stop until vehicles
move out of the loop. After vehicles move out of the loop, the gate will close.
The gate will keep opening if loop detector detects vehicles during opening. After vehicles
pass through the loop, the gate will close.
Limit switch:
The switch is used to accurately stop the gate in the opened and closed
positions.
If the gate stops at opened position when the limit switch is reached, the gate will not move
if you press
‘OPEN’ button.
If the gate stops at closed position when the limit switch is reached, the gate will not move if
you press
‘CLOSE’ button.
Adjust the pressure screw to make the output torque of the operator meet your requirement,
that is, the device should be powerful enough to move the gate and capable of making
friction plate skidding when it is blocked.
The motor is only designed to work for less than 5 minutes. If is runs continually for an
extended period of time, a thermal protector will stop it because of the high temperature.
8. Maintenance:
Please check and add transformer oil (DB25-GB2536) regularly, you may change the oil
according the weather. If the temperature is lower than
–20
º
C, you can select #45 oil.

Ensure the operator is well earthed, and correctly terminated.
Regularly grease the wheels and axles to ensure the gate moves smoothly.
Ensure the power is switched off before removing the cover.
Keep operator clean at all times.
