Code:
Connect the motor wire MOTL2 to the REV motor wire, connect MOTL1 to the FWD motor wire, and connect MOTCOM to
the motor common wire.
J3Terminal
Connect CAP to the capacitor wire.
J4 Terminal (For the convenience of wiring, this terminal is accompanied with failure diagnosis light)
OPEN: Gate open control button (N.O.)
CLOSE: Gate close control button (N.O.)
START: Open/Stop/Close/Stop loop control button (N.O.)
DET: Loop detector (sensor coil) connector (N.O.)
In the closing process, once vehicles are detected by the loop detector, the gate will open immediately; 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 some seconds later after the vehicle
passes. Change the No.4 key of the dip switch on circuit board, and the gate will close automatically some seconds later
after the vehicle passes.
STOP: Stop control button (N.O.)
PHOTO: Photocell input; NC or NO will be memorized while Travel Learning(4.3.6).
COM: Common terminal
12Vdc: Power supply for ttings: +12VDC （ Electric current ≤100mA）
J5 Terminal (For the convenience of wiring, this terminal is accompanied with failure diagnosis light)
LSC: Close limit switch
COM: Limit switch and other input signal common terminal
LSO: Open limit switch
J6 Terminal
ANT: Antenna
SHELD: GND
ravel Learning
Attention: The control board must learn the travel limit before it can be used normally.
Before the travel learning operation, you must be ensured that the limit is not triggered. Then press and hold the button
WORK. The motor will run closing rst and led CLOSING ashes. After the gate triggers the closing limit, the motor will run
opening and led OPENING ashes. When the gate triggers the opening limit, the motor will run closing again. Finally, as the
gate triggers closing limit, travel learning is completed.
Extra button
PAUSE: This button is used to set the automatic closing time .When the motor is not running, press the button and then led
STS ashes. You can press the button again to stop ashing. The automatic closing time (seconds) depends on how many
times the led STS ashes.
START: This button is equal to J4 TERMINAL's START port.
