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.
Ideal for pre-2010 installations not requiring a monitored solution.
Direct drive operator with a DC electric motor directly coupled to a hollow
shaft (30:1 reduction) worm gear reducer designed to install over keyed door shaft.
Continuous duty 0.75 HP 90 V DC 1750 rpm motor 110 to 240 V 1 PH and 60 Hz power supply.
Integral absolute encoder to control the door travel
24 V 7 amps back-up battery pack and 3/8” ratchet socket to accept and crank for manually operating the door in case of power failure
Programmable wall mountable UL325 compliant NEMA 4X control panel with LCD display and OPEN-CLOSE-STOP buttons on cover
Pulse with modulation programming to provide soft-start soft-stop dynamic brake and speed control
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).
This is installed onto the panel when the door is opened it is engaged and will keep the door open above the header so there is no hang down of the door.
The door will stay open above the header to eliminated the door being damaged.
