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 RECOMMENDED.
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 blocked or removed, the operator will go into a Restricted Close mode**.
** 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.
• Wiring for entrapment protection device to reverse.
NOTE: The operator will automatically convert to B2 wiring
when Monitored Entrapment Protection Device is installed. (See
accessories page for Monitored Entrapment Protection Devices.)
• Timer-to-Close (TTC) feature available.
