Force/Timer to Close/Party Mode Controls
Without a properly installed safety reversal system, persons 
(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 reverse on contact with a rigid 
object.

Party Mode
TTC can be temporarily disabled by pressing RESET 
button (located on the outside side of the control box) 
when the gate is fully open. This will allow the gate to 
remain open until another command is received. Following 
this command, TTC is re-enabled at the previously set 
time period.

Programming
Force Adjustment
The operator is equipped a with an obstruction sensing 
feature. If the gate encounters an obstruction the operator 
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.
To adjust the force:
 Using the 3-button remote or the Single Button Control 
(SBC) button on the control board, open and then close 
the gate.
If the gate stops and or reverses before reaching the fully 
open or closed position increase the force by turning the 
force control slightly. Run operator through a complete 
cycle.
NOTE: Weather conditions can affect the gate 
movement, so seasonal adjustment may be required. The 
force control is factory set to the mid position.
Timer-to-Close (TTC)
The TIMER TO CLOSE feature can be set to 
automatically close the gate after a specified time period. 
If the TTC is set to the OFF position, then the gate will 
remain open until the operator receives another 
command from a remote control or SBC.
To set the TIMER TO CLOSE:
Rotate the TIMER TO CLOSE dial to the desired setting. 
The range is 0 to 180 seconds, 0 seconds is OFF.
NOTE: Any radio command, SBC, or CLOSE command 
on the control board prior to the TTC expiring will close 
the gate. The TTC is reset by any signals from the loops, 
close edges, and close safety sensors (IR’s).
