This is a Current Sense Harness (230/460/575V) Replacement Kit.
Compatible with various LiftMaster® 3 Phase Logic 5.0 Commercial Door Operators; manufactured after February 2016.
Complete replacement kit includes: (2) current sense harnesses of different lengths to accommodate all models.
Models manufactured before February 2016 DO NOT feature current sense technology.
We highly recommend replacing the existing boards with an updated Logic 5.0 system that utilizes current sense technology
Refer to the following replacement boards for compatible upgrades:
K001D8395 1PH/3PH Logic Board for all L5 models
K001D8397 3PH/L5 Power Board 230/460V
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).
WARNING: When used on most industrial operators this control will not stop the door. Use another control that has a STOP button in conjunction with this control.
