NOTE:
Counter-Clockwise makes gate push harder.
Clockwise makes gate easier to stop.

Fine Tuning

The gate operator is designed to
work differently while opening then while
closing to optimize safety, so the direction of
the operator will need to be set. Setting the
operator direction is done by flipping the right/
left side switch located at the top of the
circuit board. For a left side installation flip
the switch to the left and for a right side
installation, flip the switch to the right (see
illustration above).
If it is desirable to have the gate
close automatically after the gate has
opened, flip the auto close timer switch to the
ON position. Adjust the amount of time the
gate stays open by turning the timer adjust-
ment pot counter clockwise for less time or
clockwise for more time. The range is roughly
0~45 seconds.
There are two "sensitivity" adjust-
ments on the circuit board for the open and
close directions. Turning the pots clockwise
"increase" will cause the gate to stop or
reverse more easily if there is an obstruction
preventing the gate from moving. Turning the
pots counter-clockwise "decrease" will cause
the gate to push harder before it stops or
reverses. If adjusted properly, the sensitivity
will cause the gate to reverse if the gate
meets an obstuction. Additionally, if the gate
again meets an obstruction before reaching a
limit, the gate will stop, remain stopped, and
will sound an alarm until reset with an open
input at terminal 5. If no reset is given, the
alarm will sound for approximately 5 minutes.
If adjusted too sensitive the gate may stop or
reverse under it's own weight, without being
obstructed and the sensitivity will need to be
slightly decreased. Temperature, wind, and
other environmental factors may also effect
the sensitivity so the setting should be made
with these factors in mind. Before finalizing
an installation always test the sensitivity by
applying pressure against the gate while it is
moving to make sure it will stop or reverse.
