THE MEGA ARM ALLOWS FOR THE "HANDING" OR REVERSING OF THE ARMS DIRECTION OF MOVEMENT
IN RELATION TO THE UNITS NORMAL OPERATION. THIS ALLOWS FOR MOUNTING IN TIGHT PLACES OR WHEN
IT IS DESIRED TO HAVE THE ARM , WHEN ACROSS THE DRIVE WAY, TO BE IN FRONT OF THE UNIT OR BEHIND
THE UNIT WHEN VIEWED FROM THE TRAFFIC FLOW DIRECTION.
WARNING- POWER MUST BE OFF AND NO ARM INSTALLED BEFORE MAKING THESE CHANGES
STEP 1) ONLY UNITS WITH SOFTWARE VERSIONS v4.14 OR HIGHER HAVE THIS CAPABILITY.
BEFORE POWER UP SWITCH BANK S1 SWITCH #7 MUST BE ON.
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 REVERSE TO BE (J4-7) ORANGE THEN (J4-8) BLUE.
STEP 3) AFTER COMPLETING THE STEPS ABOVE, THE CAM ARM WHICH ADJUSTS THE LIMITING POINTS OF
THE ARMS TRAVEL MUST BE TURNED 90 DEGREES TO THE LEFT WHEN VIEWED WHILE STANDING
IN FRONT OF THE CONTROL BOARD (CAM ARM 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, 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.
