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
WHERE GROUND WILL FREEZE!!)
ANCHORS (MOUNTING UNIT)
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.

IN REGIONS
PAGE 1
Page 4
NOTE 1: MAXIMUM AMBIENT TEMPERATURE FOR INSTALLATION, 104 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 ). 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 U.L. approved.
WIRING AND HOOKUP (Only by a qualified electrician/installer!)
120 VAC
Be sure your main power (120vac) is OFF before attempting hookup. The 120 volts AC supply should be
terminated to the wires in top of the 4"x4" 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 U.L. 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 120VAC 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 U.L. 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. DO NOT 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 switch 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). With S1 switch 5 on, this input
becomes a momentary pulse open, pulse close.
NOTE: Insert a jumper across the JP2 terminal to allow the interlock feature (see page 5 & 14) to work with the
multiple vehicle memory count selection, use the K1 relay to open the interlocked gate (S1-5 off, S2-6 on,
jumper across JP2). This allows gate to store input counts via J5 #4 but not raise the arm until the interlocked
slide or swing gate has fully opened.
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 positiongate 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).

Page 5
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.
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 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 VDC power maybe connected here (500
ma. maximum). EXAMPLE: Vehicle detector, radio receiver.
RELAY OUTPUT K1- (OPTION)
S1-6 off, S1-8 off
S1-6 on S1-8 off, relay will fire when arm is pushed up off of limit switch (use with slip clutch option).
and fires relay when a tail-gate is detected by the close loop -ANTI TAIL-GATE ALARM
S1-6 off S1-8 on relay will pulse relay when arm reaches full open position.
S1-6 on S1-8 on relay will only pulse when input is given to J5 1,2,3 inputs. (see page 14).
, relay will fire (latch) when gate is not closed.
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)

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
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. SET switches on S2, 1-8 the same on both gates

SWITCH - 7 AUTO CLOSE TIMER. Default is OFF. On will close gate by timer when all inputs are
cleared. Time is set by using S2 1-5 switches (WARNING-Special care should be used to avoid arm
from closing on cars. Use safety loops, stop loops, photo beams and a long enough time delay)
(Note: Can be used with multiple vehicle memory buffer to allow gate to close and reset count
memory to zero. When using clutch option, turning on S1-6 & S2-7, gate will close by timer whenever
forced up.
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 the first car passes closing loop or if
close timer S2-7 in turned on (It is recommended to allow the gate to close by loop, not by timer).

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
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 S-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 85 to 89 degrees for its full motion. Always adjust for a level arm in the
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 6) Lightly oil the new pin then insert into collar
2) Turn off AC power and disconnect batteries small end first.
3) Remove gate arm bracket and pieces in collar 7) Fully seat pin in shaft by taping on large end
4) Drive out pin pieces with hammer and punch 8) Reinstall the arm if required
(Solid sharp blows are better than light ones)
5) Reinstall gate arm bracket 10) Turn off S-3 to put gate into operation
IRD is TOO sensitive. Some slight adjustment either

TROUBLE SHOOTING AND MAINTENANCE PROCEDURES
WARNING - DISCONNECT BATTERIES AND AC POWER BEFORE
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 8 on S2 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 R63).
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
(MRT is
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)
Check for shorts in wiring. If F-3 AC fuse is blown then batteries may also be weak or dead.
1)
GATE CLOSES THEN REVERSES
1) See page 6 for IRD 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 J3, 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 12vdc sealed lead / acid type.
SERVICING ANY MECHANICAL OR MOVING COMPONENTS!!!!
MUST be check for intermittent activation, failure to rectify may result in malfunctions.

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
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
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
THEN (J4-8) BLUE.

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 UP 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
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 operator is 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 to raise again if it has closed via a car crossing the MEGA ARM's close loop.
WIRING: Run 2 wires from the other operators 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 ARMs 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
LOCKED OPEN
SENSES AN IMPACT, THE K1 RELAY WILL STAY ENERGIZED HOLDING OPEN
UNTIL THE ARM TIMES OUT AND CLOSES.
: A one second pulse from access control device to the MEGA ARM will energize its K1 relay sending an open signal to
UNTIL THE ARM REACHES THE DOWN POSITION. THIS WILL KEEP THE OTHER GATE OPERATOR
OR TEETH LOCKED DOWN UNTIL THE ARM CLOSES COMPLETELY). NOTE: IN THIS MODE IF THE ARM
