INSTALLATION
To prevent SERIOUS INJURY or DEATH from a moving gate:
• Pinch points must be guarded at all times. Install enclosed-style gate tracks and
roller guards.
• Place screen mesh 4 feet (1.2 m) high on the gate to prevent access through
openings anywhere the gate may travel.
• Mount controls at least 6 feet (1.8 m) from the gate or ANY moving part of the
gate.
• Install Warning signs on EACH side of gate in PLAIN VIEW. Permanently secure
each Warning sign in a suitable manner using fastening holes.
• This operator is intended for vehicular use only. To prevent INJURY to
pedestrians, a separate pedestrian access should be supplied, visible from the
gate. Locate the pedestrian access where there is not a chance of INJURY at any
point during full movement of the gate.
• Contact sensors MUST be located at the leading and trailing edges, and post
mounted both inside and outside a horizontal swing gate. Non-contact sensors
such as photo eyes MUST be mounted across the gate opening and operate
during BOTH the open and close cycles.
• Entrapment protection devices MUST be installed to protect anyone who may
come near a moving gate.
• Locate entrapment protection devices to protect in BOTH the open and close
gate cycles.
• Locate entrapment protection devices to protect between moving gate and RIGID
objects, such as posts or walls.
• Too much force on gate will interfere with proper operation of safety reversal
system.
• NEVER increase force beyond minimum amount required to move gate.
• NEVER use force adjustments to compensate for a binding or sticking gate.
• If one control (force or travel limits) is adjusted, the other control may also
need adjustment.
• After ANY adjustments are made, the safety reversal system MUST be tested.
Gate MUST reverse on contact with a rigid object.
• DO NOT touch the heater when switch is on, heater may be hot.
• To AVOID damaging gas, power or other underground utility lines, contact
underground utility locating companies BEFORE digging more than 18 inches
(46 cm) deep.
• ALWAYS wear protective gloves and eye protection when changing the battery
or working around the battery compartment.
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 (AC or solar and battery)
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.
• Disconnect power at the fuse box BEFORE proceeding. Operator MUST be
properly grounded and connected in accordance with national and 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.
• DO NOT install ANY wiring or attempt to run the operator without consulting the
wiring diagram. We recommend that you install an edge sensor 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.
WIRING
To reduce the risk of SEVERE INJURY or DEATH:
• Without a properly installed safety reversal system, persons (particularly small
children) could be SERIOUSLY INJURED or KILLED by a moving gate.
• Too much force on gate will interfere with proper operation of safety reversal
system.
• NEVER increase force beyond minimum amount required to move gate.
• NEVER use force adjustments to compensate for a binding or sticking gate.
• If one control (force or travel limits) is adjusted, the other control may also
need adjustment.
• After ANY adjustments are made, the safety reversal system MUST be tested.
Gate MUST reverse on contact with a rigid object.
