APPLICATION
This operator includes a number of features that will provide years
of reliable and safe operation.
FEATURES:
• Supports both monitored and non-monitored entrapment
protection devices: Entrapment protection devices detect
obstructions in the door's path and automatically reverse a
closing door.
• 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 entrapment protection 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 monitored entrapment protection device. Refer to
Basic Programming Section for descriptions of wiring types,
requirements and programming.

IMPORTANT INFORMATION ABOUT THE LIFTMASTER
MONITORED ENTRAPMENT PROTECTION DEVICES
A LiftMaster Monitored Entrapment Protection (LMEP) device
is required for most wiring types. If a LiftMaster Monitored
Entrapment Protection device is not installed, constant pressure to
close will be required from the control station.
When properly connected and aligned, the photoelectric sensors
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 photoelectric sensors must be installed facing each other
across the door, no more than 6" (15 cm) above the floor.
Each photoelectric sensor has an LED that will glow steady when
the sensor is properly connected and aligned. The LEDs on both
photoelectric sensors will flicker rapidly when obstructed or
misaligned.

RECOMMENDED INSTALLATION: B2 WIRING TYPE WITH
MONITORED ENTRAPMENT PROTECTION DEVICE
• Momentary contact to open, close and stop.
• Open override that reverses when closing by any opening
device.
• Wiring for entrapment protection device to reverse.
NOTE: The operator will automatically convert to B2 wiring when
Monitored Entrapment Protection Device is installed.
(See accessories page for Monitored Entrapment Protection
Devices.)
• Timer-to-Close (TTC) feature available.
Photoelectric Sensor
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). LIFTMASTER MONITORED ENTRAPMENT PROTECTION (LMEP) DEVICE IS RECOMMENDED.
A LiftMaster Entrapment Protection (LMEP) device is required for any momentary contact to close mode of operation including B2, TTC
and remote controls.
NOTES:
• The LED on the logic board will blink once when in C2 and twice when in B2.
• The operator will automatically convert to B2 wiring when Monitored Entrapment Protection Device is installed. If the Monitored
Entrapment Protection Device is blocked or removed, the operator will go into a Restricted Close mode**.
** 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.
