J5 (For the convenience of wiring, this terminal is accompanied with failure diagnosis light)
7. Power supply for fittings: +12V （ Electric current ≤100mA）
8. Photocell input (N.C.); short out the device if not used.
9. GND
10. Loop detector (sensor coil) connector (N.O.)
In the closing process, once vehicles are detected by the loop detector, the gate will open
soon; when the vehicle passes, the gate will close automatically. When the gate is in a
halted state, it will keep this state when vehicles are detected; after the vehicle passes, the
gate will close automatically.
In the above loop detector function, users can make the gate close automatically 12
seconds later after the vehicle passes. Change the No.4 key of the dip switch on circuit
board, and the gate will close automatically 12 seconds later after the vehicle passes.
11. Close limit switch
12. Limit switch and other input signal common terminal
13. Open limit switch
Function adjustment
Functional parameters of the control board equipped with microprocessor can be adjusted through
potentiometer and dip switch, so as to meet different installation requirements.
Adjusting knob
VR1: When meet obstacle reverse function is enabled (DIP switch 5 at OFF position and the motor
assembled the hall line). This knob is used for sensitivity adjustment of meet obstacle.
Clockwise rotation to reduce sensitivity of obstacle, counter-clockwise rotation to increase sensitivity
of obstacle.
When meet obstacle reverse function is disabled (DIP switch 5 at ON position). This knob is used for
motor working total time adjustment. Clockwise rotation to increase, counter-clockwise rotation to
reduce. The total time can be set to 10 seconds as minimum and 90 seconds as maximum.
VR2: For brake force adjustment in limit position.
Clockwise rotation to increase, counter-clockwise rotation to reduce.
Rotate to minimum to cancel brake function in place.
VR3: For slow stop width adjustment.
Clockwise rotation to increase, counter-clockwise rotation to reduce.
