INTRODUCTION UNIT OVERVIEW The DC SOLUTIONS model MEGA-ARM barrier style parking gate operator is unique in the industry. Setting the MEGA-ARM apart are many features that make it the front runner in its class. With standard features like: • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • Built in battery backup - inherent 24 VDC backup power with regulated 24VDC for accessories. High torque 24 volt Permanent Magnet DC motor .
NOTE 1: MAXIMUM AMBIENT TEMPERATURE FOR INSTALLATION, 140 F. NOTE 2: FOR AUTOMOTIVE USE ONLY, NO MOTORCYCLES, BICYCLES OR PEDESTRIANS. NOTE 3: HEATER OPTION MUST BE USED IF TEMP IS (15F) OR BELOW TEMPERATURES. CONDUITS Conduits should be restricted to fit the 3.5"x3.5" opening in pedestal base. Location on pad should be centered and spaced approximately 6" from edge of pad on drive way side ( in order to get the most reach out of arm ).
INPUT COMMANDS (Continued) 7, BACK-AWAY (FREE EXIT INPUT) This input is used as a free exit input to open gate. When input is active, gate will open and close immediately once input is removed. (EXAMPLE: Car pulls up to exit loop, gate opens; car "backs-away" from exit loop and gate closes). 8, SHAD- INTERLOCK (REDEFINED INPUT!!!) Used to monitor an auxiliary open limit switch of another operator in the same lane. Interlock with memory feature (v5.20 or higher) see page 13.
120 VAC POWER CONNECTION 120 VAC (BLACK) GROUND (GREEN) NEUTRAL (WHITE) TOP END OF 4"x4" TUBE 120 VAC CONNECTIONS ARE TO BE MADE IN TOP OF 4"x4" TUBE (POST). ONLY USE UL-LISTED 600 V WIRE INSIDE TUBE MASTER SLAVE WIRING Master-slave wire hook up. STEP 1- In a master/slave configuration, either unit can be the master. Choose one unit to be the master and then direct all control wiring to it (also install vehicle detector and receivers in it).
TIMERS AND MODE SECTIONS-(S1 and S2) FULL SPEED RUN TIMER- SWITCH PACK S1 (1-4) With all switches off the default is approximately 1.5 seconds. Changing settings will adjust fast run timer by 1/8 second increments. (Example: #2 on equals .25 seconds, #4 on equals 1 second. #2 and #4 on equals 1.25 seconds) 1/8ths SECONDS 1 2 S1 1 4 8 2 3 FAST RUN TIMER 1-4 4 5 SHOWS DEFAULT SETTINGS | MODE SELECTION 5-8 MODE SELECTIONS- SWITCH PACK S1 (5-8) SWITCH - 5.
ADJUSTMENTS INSTANT REVERSE DEVICE (IRD) The reverse device is an internal circuit that continuously monitors the motors current for increased draw. Turning the IRD1 right (CW more sensitive), or left (CCW less sensitive) in small increments will allow sensitivity adjustments (IF ARM DOES NOT REVERSE, DO NOT CONTINUE TO FORCE). The obstruction that you apply should STOP the arm. Adjust sensitivity so that consistent reversal occurs . If the gate stops while opening then the IRD is TOO sensitive.
TROUBLE SHOOTING AND MAINTENANCE PROCEDURES WARNING - DISCONNECT BATTERIES AND AC POWER BEFORE SERVICING ANY MECHANICAL OR MOVING COMPONENTS!!!! BATTERY CHECKOUT- . When the batteries become weak the gate will begin to run noticeably slower. (Note: Batteries should only be checked when you are sure they have had adequate time to fully charge). Turn off the AC power and run gate for 5 to 10 cycles while observing low battery indicator LED D12. If LED 12 comes ON, batteries are too weak to function properly.
SAMPLE CONFIGURATIONS FREE EXIT ON VEHICLE APPROACH: BACK AWAY LOOP (FREE EXIT) CLOSE LOOP GATE WILL OPEN WHEN SENSED BY EXIT LOOP AND THEN CLOSE ONCE THE CLOSE LOOP IS CLEARED. IF THE VEHICLE PULLS UP TO THE EXIT LOOP AND THEN BACKS AWAY IT WILL CLOSE. (SPACE BETWEEN LOOPS WILL BE 4' TO 10' TERMINAL # 7 IS BACKAWAY (FREE EXIT). TERMINAL # 6 IS CLOSE INPUT.

REVERSING ARM DIRECTION 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.
