Without a properly installed safety reversal system, person (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing gate.
*Too much force on gate will interfere with proper operation of safety reversal system.
*NEVER increase force beyond minimum amount required to close gate.
*NEVER use force adjustments to compensate for a binding or sticking gate.
* If one control (force or travel limits) is adjusted, the other control may also need adjustment.
* After ANY adjustments are made, the safety reversal system MUST be tested. Gate MUST BE
TESTED. Gate MUST reverse on contact with a rigid object.
The opener is equipped with an obstruction sensing feature. If the gate encounters an obstruction 3
seconds before it presses the gate block, the opener will automatically reverse direction when it close or
stop when it open. Based on the length and weight of the gate it may be necessary to make force
adjustments. The force adjustment should be high enough that small objects such as branches or wind
will not cause nuisance interruptions but low enough to prevent serious injury to a person or a vehicle.
Finally, the two gates will be back to open status. Now the limit positions have been set successfully.
Master gate open fully Slave gate open fully Slave gate close fully Master gate close
fully Master gate open fully Slave gate open fully limit position learning successfully.
The LED will display “P3” after the limit position learning successfully.
NOTE: The position learning will be failed if the Single/Dual gate setting is not correct. The LED will
display “E2” for 2 seconds and then back to “P1” setting when the position learning is failed.
Please check the Single/ Dual gate setting and the connection of the gate opener.
4. Set the Open Interval between Master and Slave Gate
When the Digital Display indicates “P3” , the gate opener is in the Open Interval between Master/Slave
Gate Setting.
The open interval can be adjusted by pressing the
“INC” and “DEC” Buttons respectively. The Digital
Display will show “0”-“9”, which indicates the interval time “0” means the Master and Slave gates open
simultaneously. “1” means the Master Gate starts to open 1 second before Slave gate starts to open. Max.
open interval is 9 seconds. Each time you press and release the “INC” button, the figure increases by 1,
and the Master gate starts to open 1 more second earlier. Each time you press and release the
“DEC”
button, the figure decreases by 1, and the interval decreases by 1 second.
(Factory default setting is 3 seconds)
Press the “
FUNC ” button to store the data when the open interval is set. The Digital Display will indicate
“P4”. Now Open Interval Set is finished.
5. Set the Close Interval between Master and Slave Gate
When the Digital Display indicates “P4” , the gate opener is in the Close Interval between Master/Slave
Gate Setting.
The close interval can be adjusted by pressing the “
INC ” and “ DEC ” buttons respectively. The Digital
Display will show “0”-“9”, which indicates the interval time ”0” means the Master and Slave gates open
simultaneously. ”1” means the Slave Gate starts to close 1 second before Master gate starts to close.
Maximum close interval is 9 seconds. Each time you press and release the “
INC ” button, the figure
increases by 1, and the Slave gate starts to close 1 more second earlier. Each time you press and release
the “
DEC ” button, the figure decreases by 1, and the interval decreases by 1 second.
(Factory default setting is 3 seconds)
Press the “
FUNC
” button to store the data when the close interval is set. The Digital Display will in dicate
“P5”. Now Close Interval Set is finished.
6. Adjust the Obstruction Sensitivity/Stall Force
When the Digital Display indicates “P5” , the gate opener is in the Stall Force Adjustment of gate opener 1.
