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 the opener will
automatically reverse direction and stop. 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.
NOTE: You may need to increase the stall force in cold weather due to increased resistance from
gate hinges. The gate opener’s opening/closing force is adjusted automatically according to stall force
adjustment.

11. Set the Fast Running Period (FRP) to Achieve Soft Stop Function (SPP)
When the Digital Display indicates “PC”, the Fast Running Period for opening or closing gate is adjustable
by pressing “INC” and “DEC” buttons respectively, and the Soft Stop Function is achieved simultaneously.
The Soft Stop means the gate opener runs at slow speed during the last period before the gate completely
closes. The Soft Stop Period is unavailable by direct adjust but available through adjusting the Fast
Running Period.
There are two running speeds designed in program, i.e. Fast Running Speed and Soft Running Speed. The
Fast Running Period is adjustable from 1 to 28 sec. Factory default setting is 15 sec.
Since the GATE OPENING OR CLOSING RUNING PERIOD (GRP) = SOFT START PERIOD (STP) +
FAST RUNNING PERIOD (FRP) + SOFT STOP PERIOD (SPP), the SPP could be extended by shortening
the FRP when the GRP and STP are fixed. In other words, SPP = GRP–STP–FRP.
Similarly, the Soft Stop Period (SPP) can be shortened through extending the Fast Running Period (FPP).
E.g. When the Soft Start Period (STP) is set at 3 sec, and the GRP is 23 sec, how can we get 4 sec of Soft
Stop Period (SPP) to meet the requirement? The answer is clear, i.e. we may set the Fast Running Period
(FRP) at 16 sec (23 –3 –4 =16 sec).
12. Return to Factory Set
When the Digital Display indicates “Pd”, press and release the “INC” or “DEC” button. All data will return to
factory set, the Digital Display indicates “dF”.
