To reduce the risk of SEVERE INJURY or DEATH:
• ANY maintenance to the operator or in the area near the
operator MUST not be performed until disconnecting the
electrical power and locking-out the power via the operator
power switch. Upon completion of maintenance the area
MUST be cleared and secured, at that time the unit may be
returned to service.
• Disconnecting power at the fuse box BEFORE proceeding.
Operator MUST be properly grounded and connected in
accordance with local electrical codes. NOTE: The operator
should be on a separate fused line of adequate capacity.
• ALL electrical connections MUST be made by a qualified individual.
AC POWER HOOKUP (120/230 Vac)
Be sure your main power is OFF before attempting to hook up the
AC power. The AC wiring should be attached to the wires exiting
the conduit or pedestal post. Only use U.L. approved 14AWG (or
larger) 600 volt insulated wire.
NOTE: Do not connect any of the AC power wires directly to the
electronic control board. Connect the batteries after the AC power
is restored.
INPUT COMMANDS CONNECTIONS
Use common and normally open contacts from devices connected
to these inputs. 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, see
Control Board Layout page 18. 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.
CAUTION: 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.
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.

WARNING
WARNING
• DO NOT install any wiring or attempt to run the operator
without consulting the wiring diagram. We recommend that
you Install an optional reversing edge BEFORE proceeding with
the control station installation.
• ALL power wiring should be on a dedicated circuit and well
protected. The location of the power disconnect should be
visible and clearly labeled.
• ALL power and control wiring MUST be run in separate conduit.
• BEFORE installing power wiring or control stations be sure to
follow all specifications and warnings described below. Failure
to do so may result in SEVERE INJURY to persons and/or
damage to operator.
AVERTISSEMENT
120 Vac
Connect the BLACK wire to the incoming 120 Vac hot lead and
AVERTISSEMENT
connect the WHITE wire to the incoming neutral lead. Connect the
GREEN wire to the ground.
230 Vac
Please purchase the 120 to 230 Vac conversion kit for 230 Vac
operation. See Accessory page.

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).
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, SHADOW (SAMS): Used to monitor an auxiliary open limit
switch of another operator in the same lane. SAMS with
memory feature, see page 18.
9, 10, 11,12 - COMMON: These are the commons (0 Vdc) to
be used to activate above inputs.
