REVERSING THE DIRECTION OF THE ARM
The MEGA ARM allows for the "handing" or reversing of the
arm's direction of movement in relation to the unit's normal
operation. This allows for mounting in tight places or when it is
desired to have the arm, when across the driveway, to be in front
of the unit or behind the unit when viewed from the traffic flow
direction (Figure 1).
WARNING: POWER MUST BE OFF AND NO ARM INSTALLED
BEFORE MAKING THESE CHANGES.
STEP 1: Before power up, switch bank S1 switch #7 must be
on (Figure 1).
STEP 2: Next, the motor wires on the control board must be
reversed. At J4 on the bottom of PCB, the last 2 wires on the
right (J4-7, J4-8) normally are blue then orange. They must be
reversed to be (J4-7) orange then (J4-8) blue (Figure 2).
STEP 3: After completing the steps above, the cam arm which
adjusts the limiting points of the arm's travel must be turned 90
degrees to the left when viewed while standing in front of the
control board (Figure 3) (cam arrow now points in the direction
of the arm and is level with mount bracket, note the small limit
sensors on the back of the PCB).
STEP 4: Now check to make sure that S1 #7 is on (Figure 1),
motor wires are reversed, the cam is adjusted, and that the
manual open/close switch (S3) is set to close. Next, turn on the
AC power and connect the batteries. Now run the gate open
and close with the S3 manual switch making sure that the
mechanism travels in the proper 90 degrees desired. Once you
are totally sure you have the correct operation, you can install
the arm
INSTALLATION NOTE: ARMS LONGER THAN 12' MUST USE THE
PROPER COUNTER WEIGHT.
