May be used in two different ways: as an Open only control (all LiftMaster operators) or as an Open/CLOSE control (only LiftMaster operators with types B2 and S2 control wiring).
In the latter case pulling the cord will Open a fully closed door close a fully Opened door and reverse a closing door.
Pulling the cord whlie the door is Opening will either have no effect (type B2 wiring) or will stop the door (Solid State Logic Control Board).
Ideal for commercial applications that require full vertical lift sectional doors with light-duty cycle requirements

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
