APPLICATION
INTRODUCTION
This Medium Duty Commercial Door Operator includes a number of features that will provide years of reliable and safe operation.
Features:
• Supports both monitored and non-monitored safety devices: Safety devices detect obstructions in the door's path and
automatically reverse a closing door. Safety devices are highly recommended by the manufacturer.
• Radio receiver: A factory installed radio receiver allows remote controls, keyless entries and other remote command devices to be
programmed to the operator.
• Timer To Close: The Timer To Close feature allows the door to automatically close after a preset time (only available with B2
wiring and a monitored safety device).
• Wiring Types: The functionality of the operator is based on the wiring type. The operator is shipped from the factory in standard
C2 wiring type (factory default). Some wiring types will require an optional safety device. Refer to Basic Programming Section for
descriptions of wiring types, requirements and programming.

PREPARATION
PREPARING YOUR DOOR
The manufacturer recommends 3' (91.4 cm) of clearance around
the operator for serviceability. Before you begin:
• Disable locks.
• Remove any ropes connected to door.
• Before the operator is installed, be sure the door has been
properly aligned and is working smoothly. Although each
installation will vary due to particular building characteristics,
refer to the following general procedures to install the operator.
To prevent possible SERIOUS INJURY or DEATH:
• DO NOT connect electric power until instructed to do so.
• If the door lock needs to remain functional, install an
interlock switch.
• ALWAYS call a trained professional door serviceman if door
binds, sticks or is out of balance. An unbalanced door may
not reverse when required.
• NEVER try to loosen, move or adjust doors, door springs,
cables, pulleys, brackets or their hardware, ALL of which are
under extreme tension and can cause SERIOUS personal
INJURY.
• Disable ALL locks and remove ALL ropes connected to door
BEFORE installing and operating door operator to avoid
entanglement.

mounting may be required due to interfering structures or location of door stile / top section
support. Typically, the operator may be mounted up to 24" (60.96 cm) off center on torsion
spring doors. Extension springs require center mounting.

WARNING
WARNINGWARNING
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.
• Disconnect power at the fuse box BEFORE proceeding.
Operator MUST be properly grounded and connected in
accordance with local electrical codes. The operator should be
on a separate fused line of adequate capacity.
POWER AND GROUND WIRING CONNECTIONS
NOTE: Power and control wiring must be run in separate conduit
in accordance with local electrical codes. Must use 14 AWG or
heavier wire for power wiring. Use conduit knockouts for wiring as
indicated on the electrical box labels.
IMPORTANT NOTE: Operator must be properly grounded. Failure
to properly ground the operator could result in electric shock and
serious injury.
Remove cover

• 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.
• Reversing devices are recommended for ALL installations.
• 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.

To protect against accidental entrapment or injury from a
moving door it is recommended that a safety device (sensing
edge or photo eyes) be installed.
IMPORTANT INFORMATION ABOUT SAFETY DEVICES
PHOTO EYES
When properly connected and aligned, the photo eye will detect
an obstruction in the path of its invisible light beam. If an
obstruction breaks the light beam while the door is closing, the
door will stop and typically reverse to the full open position.
The photo eyes must be installed facing each other across the
door, no more than 6" (15 cm) above the floor.
SENSING EDGES
When properly connected, the sensing edge will make contact
with an obstruction while the door is closing, the door will stop
and typically reverse to the full open position.
The sensing edge must be installed on the bottom of the door.
See Optional Safety Device Configurations for wiring information.

WARNING
DETERMINE THE WIRING TYPE
The functionality of this operator is based on the wiring type. The
operator is shipped from the factory in standard C2 wiring type
(factory default). Some wiring types will require an optional
safety device. Refer to the following descriptions of wiring types,
requirements and programming.
NOTE: 1. The LED on the logic board will blink once when in C2
and twice when in B2.
2. The operator will automatically convert to B2 wiring
(option D) when Monitored Safety Device is installed. If
the Monitored Safety Device is removed, the operator
will go into a Restricted Close mode**. Turn power
OFF and ON to reset wiring type.
** Restricted close mode requires a constant pressure close
command. The operator will begin closing after a 5 second
delay and will continue to close to the close limit switch. The
operator will stop if the pressure to close is released before
reaching the close limit.
To prevent possible SEVERE INJURY or DEATH, install
reversing sensors when:
• The radio is used.
• The 3-button control station is out of sight of the door.
• Or ANY other control (automatic or manual) is used.
Reversing devices are recommended for ALL installations.
C2 WIRING TYPE WITHOUT MONITORED SAFETY DEVICE
A
(Factory Default)
• Momentary contact to open and stop with constant
pressure to close.
• Open override that reverses when closing by any opening
device.
• Wiring for safety device to reverse. NOTE: The operator
will automatically convert to B2 wiring (option D) when
Monitored Safety Device is installed. (See accessories
page for Monitored Safety Devices)
