ENTRANCE GATE
conjunction with the Operating Mode switch, for powering down then mechanism when the gate
arm is broken.
The ascend and descend times are fully programmable. The vertical or clear position of the gate
arm is also programmable and can be set between 70 and 88 degrees. The maximum vertical
limit of 88 degrees is intentional to prevent the gate arm from interfering with high wind guards
and to the prevent the gate arm lights from hitting the main mast. The horizonal or "zero degree"
position is automatically set via the S-80 software once the gate arm is installed and the
horizontal buffer is adjusted to set the gate arm height at the necessary distance above the
roadway and then power is applied to the mechanism.
The positive and negative battery and GC inputs on the PCB are reverse polarity protected.
Improper application of polarity will not damage the unit.

GEAR MOTOR
The gear motor in the S-80 mechanism is a factory sealed, line replaceable unit. No lubrication of
the internal gear mechanism is required.
The gear motor has a plug coupled harness so there is no disarrangement of wires required to
replace the unit. Because the S-80 gear motor is a brushless DC type, no periodic maintenance
is required throughout the lifetime of the gear motor.
SIG-QG-21-01
Version: A
DO NOT APPLY POWER TO THE S-80 UNTIL AFTER THE GATE
ARM HAS BEEN INSTALLED, AND THE HORIZONTAL BUFFER
HAS BEEN ADJUSTED, SO THAT THE GATE ARM IS LEVEL AND
SET TO THE PROPER VERTICAL DISTANCE ABOVE THE
ROADWAY.
DOING SO WILL INCORRECTLY SET THE HORIZONTAL (ZERO
DEGREE) REFERENCE POSITION.
DO NOT UNPLUG THE MOTOR CONNECTOR FROM THE PCB
WITH THE GATE IN THE VERTICAL POSITION UNLESS THE
LOCK BAR IS IN PLACE TO RESTRICT DOWNWARD MOVEMENT.
WITHOUT THE LOCK BAR IN PLACE, THE GATE ARM WILL FALL
IN AN UNCONTROLLED MANNER IF GC IS REMOVED OR THE
BRAKE CONNECTOR IS UNPLUGGED.
