INSTALLATION PROCEDURE

CONCRETE PAD
The concrete pad for operator mounting should be approximately 24"x24"x24" in order to provide adequate weight and structure to insure proper and stable 
operation. Pad should be 6" above finished grade or even with top of curb if one is present (NOTE: PAD SHOULD ALWAYS GO BELOW FROST LINE IN REGIONS WHERE GROUND WILL FREEZE)

ANCHORS
Proper anchors for fastening operator to pad will be a 1/2"x6" wedge anchor patterned to match the mounting base of the unit. They should be installed with 
approximately 1.25" showing above concrete surface in order to allow for the 1/2" thick base plate as well as washers for leveling.

Top


NOTE 1: MAXIMUM AMBIENT TEMPERATURE FOR INSTALLATION, 104 FAHRENHEIT
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).  Conduits to be included should be 120 VAC main power low voltage control wiring and one or two extra for loop sensor leads.  Conduit size should be limited to .5" when possible to reduce crowding if more than four are needed All conduits must be UL approved.

WIRING AND HOOKUP (Only by a qualified electrician/installer!)
120 VAC

Be sure your main power (l2Ovac) is OFF before attempting hookup The 120 volts AC supply should be terminated to the wires in top of the tube at the top 
of the chassis.  Connect the 120 VAC to BLACK wire, Neutral to the WHITE wire and Ground the GREEN wire. Warning:  Do not connect any 120 VAC wires directly to the terminal strips on the electronic control board.  Only UL approved 14 AWG ( or larger) 600 volt insulated wire should be used.  A separate UL approved 10 amp circuit breaker should be used for each MEGA-ARM operator.  BATTERIES MUST BE INSTALLED AFTER 12O VAC POWER IS TURNED ON.  See BATTERY at page 3 and 120 VAC wiring on page 4.

INPUT COMMANDS

Control wire connections at low voltage terminal strip will be at the top of the electronic control board.  Make connections to the appropriate points for the desired operation.  Wires should be UL approved 600 volt rated and at least 18 awg.  They are to be routed through the upper grommet in chassis to avoid chafing.  All external control devices must have normally open dry contacts. CONNECT ANY DEVICE WHICH WOULD DELIVER ANY VOLTAGE OF ANY KIND TO THESE TERMINALS.  Terminals 9,10,11 12 are the commons (0 VDC) used to activate the following inputs.

1, 2, 3 OPEN These inputs will trigger gate open when pulsed or hold gate open with maintained contact.  When released gate will close if closing timer is on or if close input is given.

4, AUXILIARY OPEN - Same as 1,2 and 3 with S2 witch 6 off.  With S2 
switch 6 On, this input will memorize multiple vehicles and not allow gate to close until the final vehicle in memory crosses the close loop.  Use with laser scanners .or card readers and transmitters with timed anti-pass back.

5, SAFETY - This input is generally not used with the MEGA-ARM.  If  used its function is to make gate reverse and go back to the open position if it was closing.  Input is disabled when gate is closed.

6, CLOSE - When used with a vehicle detector, it is recommended that the presence contacts (N.O. & C.) be used for the close input.  This input will close gate after input is applied and then removed.  It will stop the open cycle and reverse gate to close. (Example: Car crosses over close loop before arm reaches full open position gate will reverse and close).  (Note: The close input also acts as a safety-stop in that if gate is closing and a tailgater is sensed at the close input, the gate WILL STOP its closing motion and not continue to close until the close input is removed or gate is re-opened).

Top


INPUT COMMAND  (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 If gate is opening and this input is removed the gate will reverse and close. If this input is followed by another input (open safety or close) gate will continue with its new command.  (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.

9, 10, 11, 12 - COMMON - These are the commons (0 VDC) to be used to 
activate above inputs..

Note: Above inputs are tied to LED indicators to show input command activity.


ACCESSORY AND RELAY CONNECTIONS

These terminals will provide battery backed power to 24 VDC devices and are located at the bottom of the electronic control board at terminals 1 and 2.  Terminal 1 is 24 VDC (+) and number 2 is 0 VDC (-). Peripheral CLASS 2 low voltage devices that require 24 VDS power maybe connected here (500 ma. maximum). EXAMPLE: Vehicle detector radio receiver.

RELAY OUTPUT K1 - (OPTION) With S1-8 off this relay energizes when 
the. gate arm is in all positions except closed With 51-8 on it will pulse when the open limit sensor is reached to activate a swing gate slide gate or other device.


BATTERY INSTALLATION

HOOKING UP BATTERY LEADS - ALWAYS HOOKUP AND TURN ON AC POWER BEFORE INSTALLING BATTERIES.  After turning on AC power install two new fully charged 12 volt DC batteries on shelf next to motor. Connect red lead from operator to the positive (RED +) terminal of one battery and black lead from the operator to the (BLACK-) terminal of the OTHER battery.  Place the supplied jumper between the remaining terminals of each 
battery if one is not already in place.  See diagram. (USE YUASA BRAND PN#NP7-12)

WARNING-DO NOT RUN OPERATOR WITHOUT INSTALLING THE BATTERIES

Failure to install batteries correctly WILL cause damage and WILL not be covered by warranty.

120 VAC POWER CONNECTION

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)

STEP 2 - At the MASTER any input (at J5) with control (detectors receivers keypads timers etc.) wires to it must also be run to the same terminals of the slave Along with these control wires both operators MUST share a common ground connection from chassis to chassis (or from common to common, i.e. 
master gate J5 terminal #12 to slave gate J5 terminal #12)
EXAMPLE: If only open and close are used at master then three wires will run between gates.

STEP 3 - If it is required that if one gate senses an obstruction the other reverses also then 3 additional wires must be run between the master J3 and slave J3 as shown below these connections are for transmitting IRD (obstruction signals) between both units This will allow the master or slave to inform the other that a closing obstruction has occurred and for it to also reverse and open ALWAYS 
set the DIP switches on S2, 1-8 the same on both units.

IRD OBSTRUCTION SIGNAL CONNECTIONS

THE CONNECTIONS TO THE LEFT MUST BE DONE IN ORDER FOR GATE IRD'S TO WORK CORRECTLY.  TERMINAL 1 OF MASTER MUST GO TO TERMINAL 4 OF SLAVE AND TERMINAL 1 OF SLAVE MUST GO TO TERMINAL 4 OF MASTER TERMINAL 2 OF MASTER WILL GO TO TERMINAL 2 OF SLAVE

TIMERS AND MODE SELECTIONS - (S1 and S2)

FULL SPEED RUN TIMER - SWITCH PACK S1 (1-5) DO NOT CHANGE SETTINGS  The full speed run timer must be left at the factory setting of all "OFF" when used with the MEGA-ARM barrier operator.  With all switches off the default is approximately 1 5 seconds.

MODE SELECTIONS - SWITCH PACK S1 (6-8)

SWITCH - 6. ON -Will fire relay if gate is pushed UP from closed limit, used with clutch option
SWITCH - 7. USED TO ENABLE ARM TO WORK IN REVERSE DIRECTION, SEE page 11.
SWITCH - 8. Off will make K1 relay activate during open cycle( use with buzzers, counters, etc..) On will pulse K1 relay when OPEN LIMIT (OLS) is reached (activates a swing or slide gate its lane).

CLOSE TIMER - SWITCH PACK S2 (1-5)
On the MEGA-ARM the switches 1~5 on 52 are for the closing time delay to select the period of time that the gate stays open after the obstruction sensor has revered and re-opened the arm or if the S2-7 timer to close is turned on.   The default will keep the gate up for 4 seconds to allow the vehicle to be moved from the gate arm path.  Changing settings 1 5 will increase or decrease this hold open time.  The default of 1,2,4,5 OFF AND 3 ON will provide a 4 second close time delay.

MODE SELECTIONS -  SWITCH PACK S2 (68)

SWITCH - 6, INPUT MEMORY Activates multiple vehicle memory at aux input terminal #4 on J5.
SWITCH - 7 AUTO CLOSE TIMER. Default is OFF NOT RECOMMENDED FOR MEGA-ARM.
SWITCH - 8 AUTO OPEN ON POWER FAILURE. When switch number 8 is in the ON position, the operator will automatically open the gate approximately 15 seconds after the loss of power.  Once power is restored the operator will resume normal operation after tile first car passes closing loop.

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. Some slight adjustment either way may be needed in order that the gate only reverses when obstructed.  If gate is obstructed while closing, gate will reverse to the open position, time out (using the time delay set at S-2 switches 1-5) and then close. If gate is opening when obstructed, gate will stop its open travel, then will time out and close using the same delay set at S-2.  If 6-2 switch number 8 is off (you have programmed the unit to NOT AUTO RAISE when power fails) then recheck your adjustments with AC power off to be sure proper operation will be maintained.

NOTE-INSTANT REVERSE DEVICE (IRD) SHOULD BE TESTED MONTHLY TO INSURE PROPER OPERATION. IF ADJUSTMENTS ARE REQUIRED, REFER TO ABOVE PARAGRAPH. ADJUSTMENTS TO BE DONE BY QUALIFIED SERVICE PERSONS ONLY.

GATE ARM INSTALLATION AND LEVELING
Install arm in gate arm bracket by lining up holes in arm with the slotted holes in bracket. Insert the bolts through the arm and through the bracket. Next install the 
flat washers then the nylon nuts. (It is recommended the only nylon nuts be used to attach arms). The magnetic limit cam is pre-adjusted for near proper arm travel, however if leveling of the arm is required this can be done through adjustment to the magnetic cam arm. Note that during these adjustments the arm only travels
approximately 55 to 89 degrees for its full motion. Always adjust for a level arm in the HORIZONTAL POSITION. There is a small set screw in the side of the cam arm which can be loosened to allow the cam arm magnet to reach the close limit sensor (located on back of controller, H2) earlier or later in its travel. Continue to open and close the gate while adjusting until a satisfactory horizontal stopping
point can be maintained. Afterwards re-secure set screw in cam arm. (Note: In some cases additional adjustments may be required after the belt wears in). When 
stopping in the open position, the arm will stop just before the full vertical position.

NOTICE: TO PREVENT ENTRAPMENT, ALLOW FOR TWO (2) FEET MINIMUM CLEARANCE PAST END OF ARM WHEN IN DOWN POSITION.

SHEAR PIN REPLACEMENT
If gate arm is vandalized and the tapered pin in the output shaft has been sheared, it must be replaced correctly and with the right pin type. Replacement must be done by always punching out the pin (or pieces) from the small end only. If drilling is required, DO NOT DAMAGE THE SHAFT, use a drill bit smaller than the small hole size of the pin. (Correct pin is a 2" pin with a number 6 taper only).

NEVER USE A BOLT AS A TEMPORARY FIX, THIS WILL DAMAGE THE SHAFT AND COLLAR
1) Use S-3 to rotate bracket to up position
2) Turn off AG power and disconnect batteries
3) Remove gate arm bracket and pieces in collar
4) Drive out pin pieces with hammer and punch (Solid sharp blows are better than light ones)
5) Reinstall gate arm bracket
6) Lightly oil the new pin then insert into collar small end first.
7) Fully seat pin in shaft by taping on large end
8) Reinstall the arm if required
9) Turn on AC power and connect batteries
10) Turn off S-3 to put gate into operation

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.  If LED 12 does not light, then voltage should be checked as they still maybe near failure.  Correct voltage is approximately 24~5VDC (Note:. If LED D12 does light, gate will open to conserve batteries in this test or in a real power loss, even  if mode switch a on 32 is off).  Return of AC power will clear low battery
indicator.  Correct charge voltage is 27.5 VDC with batteries not connected (adjustment is at RGS).

GATE WILL NOT CLOSE

1) Check for any active inputs, AC power loss, AC power switch is off or weak batteries.
2) Check that batteries are connected properly
3) Is switch S-3 in on position (this is. manual open switch)
4) Check for S-2 switch number 8 is in on position and if AC power is lost, see LED D14.
5) Check LED D12, if lit and AC power is off, then batteries needs to be charged or replaced.

GATE WILL NOT OPEN

1) Check for AC power loss at D14 (check AC power switch) and that batteries are fully charged.
2) Check fuses and if inputs are wired correctly, test S-3 manual open switch.

GATE DEAD, NO OPERATION

1) Check LED D14 for AC power indication and check AC power switch is on.
2) Check LED D11 for Heart Beat pulses, if none and D14 (AC) & D5 (Brake) are on, then gate has repeatedly sensed obstructions. Clear obstruction then clear with next new input.
3) IRD (D2) LED is flashing, MRT has expired.  H1, H2 (Hall sensors) and clearance to magnet on cam. MUST be check for intermittent activation, failure to rectify may result in malfunctions (MRT is Maximum Run Timer that disables the gate if the magnet does not reach H1 or H2).
Reset the AC and battery power to clear this once you have rectified the problem.

FUSE(S) ARE BLOWN, F-3 (10 AMP AC) AND / OR F-4 (15 AMP DC)

1) Check for shorts in wiring.  If F-3 AC fuse is blown then batteries may also be weak or dead.

 "Warning - For Continued Protection Against Fire,
 Replace Only With The Same Type And Rating Of  Fuse"

GATES CLOSES THEN REVERSES

1) See page 6 for RD adjustments also check for obstacles in gate travel, trees, etc....
2) Charge voltage to batteries too low, adjust at R63. With batteries disconnected set to 27.5.

IRD OBSTRUCTION SIGNAL TO OTHER GATE NOT WORKING CORRECTLY

1) Remove connector at J13, obstruct arm, LED D13 should go off for a few seconds.  This indicates signal was transmitted.  Be sure gates share a common ground (See master slave pg 4).

GENERAL SERVICE

1) Belt loose or needs replacement, adjust with 4 bolts that support motor to allow 1/4 inch play.
2) Charge voltage for batteries should be 27.5 VDC with batteries disconnected (set at R63).
3) Replace batteries with Yuasa, pn# NP7-12, 7 amp hour l2vdc sealed lead / acid type.

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.
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  #71S 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.

INSTALLATION NOTE: ARMS LONGER THAN 12 FEET MUST USE THE PROPER COUNTER WEIGHT

INTERLOCK WITH MEMORY FEATURE


INTERLOCK WITH OTHER OPERATORS: (REQUIRES THE K1 RELAY OPTION)
VERSIONS 5.20 OR GREATER NOW HAVE THE ABILITY TO ALLOW THE MEGA-ARM TO MONITOR FOR THE FULL OPEN POSITION OF A SLIDE, SWING, VERTICAL PIVOT, ROLL LIP OR OVERHEAD OPERATOR AS WELL AS THE DOWN POSITION OF MOTORIZED TRAFFIC TEETH (MTC-31) AND RAISE THE ARM ONCE FULLY OPEN.


This new feature will allow a logical interface between the MEGA ARM barrier gate and a swing, slide, etc... gate operator (or MTC-31). All that is required is 4 wires between the Mega Arm barrier gate and the other operator. It will be necessary to have one set of dedicated/isolated dry contacts-{C. & N.C.} COMMON & NORMALLY CLOSED be available at the other operators OPEN LIMIT SWITCH. Most units will require that this EXTRA limit switch be added to their open limit switch assembly.  
OPERATION:. A one second pulse from access control device to the MEGA ARM will energize its K1 relay sending an open signal to the other operator causing it to open, however, the MEGA ARM's boom will not raise yet. When the other operator reaches its full open limit switch, this will open the COMMON & NORMALLY CLOSED contact on the EXTRA open limit switch. This will allow the original signal from your access control device (that was stored in memory) to now raise the gate arm. As long as the other operators in the full open position, any additional open pulse sent will in turn energize the MEGA ARM's K1 relay to send another open signal to the other operator as well as cause the arm braise again if it has closed via a car crossing the MEGA ARM's close loop.

WIRING:  Run 2 wires from the other operator isolated common & normally closed contacts of its open limit switch to the MEGA ARM J5#8 and one of the commons J5, #9-12. Next run 2 wires from the MEGA ARM's K1 relay (common & normally open) to the other operators common and open input. (WARNING: max of 30 VOLTS @ .5 AMPS THROUGH RELAY). J5 #8 was the unused SHADOW LOOP input on the MEGA ARM. Note: A separate open device (24 hour timer, toggle switch) can be run to the other operator to control it without raising the gate arm. Tampering with the other operators safety loops, safety edges and reverse sensors WILL NOT cause the arm to raise if one tripped the arm will only raise if an intended open signal was sent to the MEGA ARM.

NOTE: FOR MOTORIZED TEETH, VERTICAL PIVOT OR OVERHEAD OPERATOR, LEAVE S1-6, S1-8 OFF (THIS WILL KEEP THE K1 RELAY LATCHED UNTIL THE ARM REACHES THE DOWN POSITION. THIS WILL KEEP THE OTHER GATE OPERATOR LOCKED OPEN OR TEETH LOCKED DOWN UNTIL THE ARM CLOSES COMPLETELY). NOTE: IN THIS MODE IF THE ARM SENSES AN IMPACT, THE K1 RELAY WILL STAY ENERGIZED HOLDING OPEN. (OR TEETH DOWN) THE OTHER OPERATOR UNTIL THE ARM TIMES OUT AND CLOSES.

INTER-LOCK TWO MEGA ARMS WITH "MEMORY":
REQUIRES THE K1 RELAY OPTION
NOTE:  (5.20 or greater) can be used when you have two entry gates that you want to INTER-LOCK with each other. This is when you can only have ONE gate raised at a time (bottle neck or gates at a cross street).  In this case, which ever one raises first will get first priority, while if the other gets an open signal, it will be HELD IN MEMORY then raise once the first gate closes. This will work
if either gate has a telephone entry unit or access device (AVI, prox , etc...). Connect the K1 relay C & N.O. of each gate to the SHADOW LOOP J5 #8 input & common of the other (Leave S1-6 & 8 OFF to allow relay to stay 
latched).
