Light curtain made up of a series of thru-beam photo eyes designed to provide a dense barrier of protection for motorized or high speed doors.
Ideal for environments that require expanded protection for protruding parts that may not be detected by standard single-beam photo eyes mounted 6" above the floor.
Monitored safety inputs: 3 Main Board 3 Expansion Board.
Temperature specs: Without Heater: -4°F (-20°C) to 140°F (60°C). With optional heater (HTRNB: HTR460 for 460V operators): -40°F (-40°C) to 140°F (60°C)
Gearhead style commercial door operators employ lubricated gears for heavy industrial high cycle applications.
GH-style operators include a floor level chain hoist to ease manual operation in an emergency or power outage.
Hoist wheel is easily moved to Right or Left hand side of unit eliminating the need to order right or left hand mounting.
MyQ Technology enables you to securely monitor and control your facility operator with your smartphone tablet or computer. Internet Gateway 828LM required.
Security +2.0 radio receiver safeguards your facility - with every click a new code is sent to the commercial door operator so the door opens only for you.
Timer-To-Close: Conveniently and confidently closes the commercial door automatically after a predetermined amount of time has elapsed for added security and peace of mind.
The travel nut on LA500DC and LA500DCS gate operators may break when excessive force is applied to the gate such as being struck from a vehicle.
The travel nut can be identified as the white plastic nut that attaches to the internal lead screw of the arm.
The symptom of this problem is that the trolley assembly slides back and forth along the guide slots without mechanical restraint.
LiftMaster has created Trolley Service Kit K75-39337 with all the necessary parts and provides instructions on how to replace a damaged travel nut
within an LA500 arm
