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).
