C DIMENSION For C dimension, the measurement is taken from the Phobos pivot point
to the center of the arge ho e on the gate bracket WITH THE GATE ON ITS FULLY
CLOSED POSITION.

A & B DIMENSIONS For A and B dimensions, the measurement is taken from the center
of the gate's hinge point to the center of the Phobos pivot point.
SQUARE WITH THE GATE It is very important that the measurements are taken using
the gate frame fu y c osed as perpendicu ar ang e reference. If a fu y c osed gate is not
square with the gate post, you must make the proper ang e adjustments.

Table 2.1
IDEAL GEOMETRY A symmetrica geometry wi give you even speed and torque throughout the entire
movement of the gate as we as equa y strong everage to ho d the gate in position at both open and c ose ends
of strokes. If you are we ding the post bracket, when possib e, use the geometry in tab e 1:
Table 1
USING THE ARB BRACKETS The ARB adjustab e brackets simp ify the insta ation process.
The tab es 2.1 and 2.2 gives you different options depending on the three most common gate
hinge offsets. These dimensions on y app y to insta ations where the fu y c osed gate is square
with the gate post. DO NOT DEVIATE FROM THE DIMENSIONS ON THE TABLES

1) DETERMINE THE PROPER GEOMETRY FOR YOUR INSTALLATION. You can use the tab e be ow to
write down your dimensions.
3) BOLT AND/OR WELD THE GATE BRACKET ACCORDING TO YOUR GEOMETRY. Remember to
measure the distance to C with a fu y c osed gate.
WELD OR BOLT
4) INSTALL THE MAGNET HOLDER OVER THE GATE BRACKET. Do
not insta before or right after we ding. Wait for bracket to coo down. Do
not try to operate the actuators without the magnet ho der in p ace.
2) BOLT AND/OR WELD THE POST BRACKET ACCORDING TO YOUR GEOMETRY.

1) WIRE THE MOTORS Before attaching the actuator to the mounting brackets, wire
the motor cab e and then insta the protective cover as i ustrated.
2) ATTACH THE ACTUATOR Fo ow i ustrations to insta the actuator to the post and gate
brackets.
INSTALLING THE ACTUATOR

1) SET TO MANUAL OPERATION - Disengage the drive gear by using the triangu ar key and turning
c ockwise.
2) SET THE CLOSE LIMIT - Push the gate to its fu y c osed position. Remove the screw that ho ds the
proximity sensor at the front end of the actuator. S ide it back so that the back end of the sensor
housing is 3-1/2” from the center of the drive carriage and re-attach screw that secures sensor in
p ace.
3) SET THE OPEN LIMIT - Push the gate to its fu y
open position. Remove the screw that ho ds the
proximity sensor c osest to the actuator body. S ide it
forward so that the back end of the sensor housing is
3-1/2” from the center of the drive carriage and re-
attach screw that secures sensor in p ace.
3-1/2”
4) RE ENGAGE THE MANUAL RELEASE - Use triangu ar key and turn counterc ockwise to re-
engage gears.
