LO G IC OWNER'S MANUAL MODEL GH LOGIC CONTROL (VER. 2.0) INDUSTRIAL DUTY DOOR OPERATOR C L O N TR O L FACTORY SET C2 Wiring See pages 14 and 15 for other wiring configurations PATENT PENDING The Maintenance Alert System TM allows the installer to set an internal Maintenance Cycle Counter. An LED on the 3-button station will signal when the set number of cycles is reached or when the opener requires immediate service.
Before attempting to install, operate or maintain the operator, you must read and fully understand this manual and follow all safety instructions. These instructions are intended to highlight certain safety related issues. These instructions are not intended to be comprehensive. Because each application is unique, it is the responsibility of the purchaser, designer, installer and end user to ensure that the total door system is safe for its intended use.

IMPORTANT SAFETY NOTES CAUTION WARNING WARNING TO AVOID DAMAGE TO DOOR AND OPERATOR, MAKE ALL DOOR LOCKS INOPERATIVE. SECURE LOCK(S) IN "OPEN" POSITION. IF THE DOOR LOCK NEEDS TO REMAIN FUNCTIONAL, INSTALL AN INTERLOCK SWITCH. DO NOT CONNECT ELECTRIC POWER UNTIL INSTRUCTED TO DO SO. KEEP DOOR BALANCED. STICKING OR BINDING DOORS MUST BE REPAIRED. DOORS, DOOR SPRINGS, CABLES, PULLEYS, BRACKETS AND THEIR HARDWARE MAY BE UNDER EXTREME TENSION AND CAN CAUSE SERIOUS PERSONAL INJURY.
OPERATOR MOUNTING Before your operator is installed, be sure the door has been properly aligned and is working smoothly. The operator may be wall mounted or mounted on a bracket or shelf. If necessary, refer to the operator preparations on page 3. Refer to the illustration and instructions below that suits your application. 1a. Wall Mounting The operator should generally be installed below the door shaft, and as close to the door as possible.
8. Mount Chain Keeper / Keyhole Bracket Using suitable hardware mount the chain keeper approximately 4 feet above the floor, near the free hanging chain. Remove disconnect sash chain from bag and place the end through the keyhole in the the chain keeper. Remove excess links if necessary. 7. Install Hand Chain Place hand chain around hand chain wheel. Be sure to pass it through both openings in the chain guide.
ENTRAPMENT PROTECTION ACCESSORIES (OPTIONAL) CONT’D PHOTO EYES & SENSING EDGES Sensing devices supplied for door industry type operators with an isolated normally open (N.O.) dry contact output IT IS STRONGLY RECOMMENDED THAT A are compatible with your operator. This includes through SAFETY PHOTO EYE OR SENSING EDGE BE beam and retro reflective photo eyes, and pneumatic and USED IN CONJUNCTION WITH THE OPERATOR. electric edges.
INSTALL POWER WIRING & CONTROL STATION Before installing power wiring or control stations be sure to follow all specifications and warnings described below. Failure to do so may result in severe injury to persons and/or damage to operator. The operator electrical box is only to be accessed by trained “LIFTMASTER” technicians. If service is required contact your local LIFTMASTER dealer. Do not install any wiring or attempt to run the operator without consulting the wiring diagram.

ADJUST TORQUE LIMITER CLUTCH (OPTIONAL MODIFICATION) 1. Loosen set screws on clutch nut. 2. Back off clutch nut until there is very little tension on the clutch spring. 3. Tighten clutch nut gradually until there is just enough tension to permit the operator to move the door smoothly but to allow the clutch to slip if the door is obstructed. When the clutch is properly adjusted, it should generally adjusted, it should generally be possible to stop the door by hand during travel.

Refer to printed circuit board illustration on page 19 for all component locations. Before Programming the logic board, set the operators open and close limits. LEDs on the logic board are provided to assist setting the limits. As each limit is activated the corresponding LED will light up. The abbreviations are Open Limit Switch (OLS), Close Limit Switch (CLS) and Sensing Limit Switch (SLS). Refer to page 7 for limit switch adjustment instructions.
