IMPORTANT INFORMATION ABOUT THE LIFTMASTER
MONITORED ENTRAPMENT PROTECTION DEVICES
A LiftMaster Monitored Entrapment Protection (LMEP) device is
required for most wiring types (refer to page 29). The operator
comes standard with the photoelectric sensors model CPS-U,
additional entrapment devices are available for purchase
(see accessories). 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
AVERTISSEMENT
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.
ATTENTION
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.
