INTRODUCTION

Congratulations on purchasing a quality, LiftMaster Medium Duty Commercial Door Operator. Your new operator is capable of operating up to 12 cycles per hour or 50 cycles per day. It is equipped with a built in radio receiver that is compatible with our existing 315 MHz product line as well as a Timer-to- Close (TTC) feature that can be enabled when LiftMaster Commercial Protector System® is installed and aligned properly.

BASIC PROGRAMMING

DETERMINE THE WIRING TYPE

The functionality of this operator is based on the wiring type. The operator is shipped from the factory in standard C2 wiring type (factory default). LIFTMASTER MONITORED ENTRAPMENT PROTECTION (LMEP) DEVICE IS REQUIRED.

NOTES:

The LED on the logic board will blink once when in C2 and twice when in B2.
The operator will automatically convert to B2 wiring when Monitored Entrapment Protection Device is installed. If the Monitored Entrapment Protection Device is removed, the operator will go into a Restricted Close mode**. Turn power OFF and ON to reset wiring type.

** Restricted close mode requires a constant pressure close command. The operator will begin closing after a 5 second delay and will continue to close to the close limit switch. The operator will stop if the pressure to close is released before reaching the close limit.

RECOMMENDED INSTALLATION: B2 WIRING TYPE WITH MONITORED ENTRAPMENT PROTECTION DEVICE

Momentary contact to open, close and stop.
Open override that reverses when closing by any opening device.
