OPERATION

Reset Button

The reset button is located on the outside of the control box and serves several functions.
Obstruction/Entrapment Reset
If gate encounters two consecutive obstructions, the control system will go into an entrapment alarm condition and the
control board will require resetting. This is achieved by simply pushing the "Reset Button" located on the outside of the
control box.
Party Mode (Timer Defeat - Hold Open)
When the "Timer to Close" feature is activated for normal daily operation and
you wish to leave the gate(s) in the open postion for any extended period of
time you can activate the "Party Mode" by pushing the "Reset Button" located
on the outside of the electrical box. To exit this mode, simply give the gate(s)
a command to run by using the remote control. This will close the gate(s) and
return the operator to normal operation.

Remote Control

Once the remote control has been programmed unit will operate as follows:
When gate is in the closed position, activation of the remote control button will open the gate. During the open cycle
another activation of the remote control will stop the gate and the next activation of the remote control will close the gate.
When the gate is in the open position, activation of the remote control
button will close the gate. During the close cycle another activation of the
remote control will stop the gate and the next activation of the remote
control will open the gate.

Manual Release

The drive mechanism can be released. The gate can then be operated manually (power failure). With a new drive
mechanism, the release action may sometimes feel stiff/jerky. This is normal and has no effect on function.
