LO G L IC OWNER'S MANUAL MODEL GT LOGIC CONTROL (VER. 2.0) INDUSTRIAL DUTY DOOR OPERATOR C 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.

OPERATOR PREPARATION 4. Connect the track to the powerhead by fastening two 3/8"-16 x 3/4" bolts and nuts through the frame and the end holes in track. Tighten all four bolts to secure the track to the powerhead. WARNING WARNING 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 OR DEATH.
INSTALLATION INSTRUCTIONS IMPORTANT NOTE: Before the operator is installed, be sure the door has been properly aligned and is working smoothly. Although each installation will vary due to particular building characteristics, refer to the following general procedures to install the operator. MOUNT HEADER BRACKET The trolley operator is generally mounted over the center of the door. However, off center mounting may be required due to interfering structures or location of door stile / top section support.
INSTALLATION INSTRUCTIONS STRAIGHT ARM ATTACHMENT 1. Fully close the door and move the trolley slider to within (2”) two inches of the front idler. OPERATOR SUPPORT 1. The illustration below shows a typical method of hanging the operator from the ceiling. Each installation may vary, but in all cases side braces should be used for additional strength. 2. Latch the straight door arm to the fixed roll pin in the trolley carriage. Make sure the open side of notch on the arm faces the doorway. 2.

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.

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.
