PROGRAM SETTINGS Logic Control Pushbuttons Open, Close, Stop Open, Close and Stop buttons are mounted directly on the Logic Control board. This will provide easy programming ability and door control at the electrical box. Programmable Maximum Run Timer: Any time a “closing” or “opening” door takes 10 seconds longer than its programmed normal cycle time, the door will stop.
Page 16
WIRING TYPES All modes contain: Wiring for sensing devices to reverse. Wiring for failsafe reversing devices. Connection for electrical detection of clutch slippage. External interlocks and auxiliary devices. Open button override while door is traveling down. NOTE: Open, Close, and Stop buttons are located on the Logic Control board. This will provide programming ability and door control at the electrical box.
See Failsafe Safety Device Options below. Failsafe Safety Device Options To use the operator in any of the Failsafe wiring modes, or Timer to Close wiring modes, a LiftMaster failsafe safety device must be installed. FAIL SAFE Timer to Close with Failsafe Safety Device NOTE: The board will check attached Failsafe devices after setting the Timer to Close and activate them for the timer.
