Obstruction Sensitivity Set Up
IMPORTANT: For safety reasons the obstruction setting
or stall force on the Zareba Automatic Gate Opener
control board comes from the factory set at minimum,
turned all the way counter-clockwise. In many gate
installations, this setting will need to be adjusted to
overcome the weight and size of the gates.
The stall force potentiometer on the circuit board con-
trols the obstruction sensitivity (or the amount of force
the opener will apply to an obstruction) before it auto-
matically stops and reverses direction of the gate after
approximately two seconds. Adjust the sensitivity
beginning at the factory default counter-clockwise posi-
tion (fig. 46). Continue to incrementally increase the
force until the gate can open and close without
obstructing under its own weight.
NOTE: You may need to increase the stall force in cold
weather due to increased resistance from gate hinges.
Work safely when adjusting or servicing your automatic
gate opener.
Accessory Installation
Before installing accessories to the control board, set
the control box power switch to the OFF position.
Accessories from Zareba include instructions detailing
how to connect them to the control box. Please refer to
those instructions. Note: Accessories connected to your
system will draw additional power from the battery.
If using an accessory brand other than Zareba, please
refer to the manufacturer's manual. If technical support
is required, please contact the manufacturer of the
accessory item. Zareba Systems is not liable or responsi-
ble for non-Zareba branded accessories.
For a list of all optional accessories, see
page 34.

Charging the Battery
Upon initial installation, the battery may not be charged
adequately. To ensure proper operation allow the bat-
tery to charge prior to operation. The battery can be
charged in one of two ways:
1. Disconnect the battery from the control board, and
hook up to a 2 amp battery charger.
2. Ensure battery and AC power is properly connected.
Do not operate the gate for 4 hours allowing the bat-
tery to charge.
While the battery is charging, the red CHARGING light
will be lit. Once fully charged, the red CHARGING light
will no longer be illuminated (see fig. 44, on page 27
for location of lights).
Gate Opener Operation
During normal operation your gate opener will respond
to an input (from a transmitter, keypad, push button,
etc.) by opening a closed gate or closing an open gate.
If an input is given to a moving gate, the gate will stop.
An additional input will cause the gate to reverse the
direction it was moving.
Your gate opener has a self-correcting mechanism to
accommodate the following rare conditions:
In Pull-To-Open Installations:
If your gate, while in a stationary position, has been
subjected to heavy winds or an excessive force has
moved the gate, it may be necessary for the gate open-
er to self-correct and return to a “zero” position. In this
state, if an input is received, the gate will emit an audi-
ble alarm and return to a fully open position. Once the
gate opener has self-corrected, the gate will complete
the function of the last input received. It is important
that you allow the gate to self-correct and do not press
any input devices until the process is complete.
