PROGRAMMING

INTRODUCTION TO PROGRAMMING

Many programmable functions require that a LiftMaster Entrapment Protection (LMEP) Device be installed in order to function.
Before programming the logic board, set the operator's 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).
When power is applied to the operator, the following LED's will
illuminate: STOP, CLOSE, OPEN, LMEP, 24Vac, RADIO, DATA,
TIMER ENABLE, OLS MID, SLS, CLS, and MAS. Once the power
up process is completed (approximately 2-3 seconds) only the
appropriate LED's will continue to be lit (i.e., STOP, 24Vdc, limit
LED(s) if limit(s) is activated).
NOTE: When the power up process is over, the MAS LED will
blink a code indicating the version of firmware. If the selector dial
is in the DIAG, OPTN, or PROG position, the MAS will not provide
this code. After the code has been provided the MAS LED will go
out.

LOGIC BOARD PUSH BUTTONS (OPEN, CLOSE, STOP)
Open, Close and Stop buttons are mounted directly on the logic
board. Thus, making it easy to program as well as having the door
control at the electrical box.
Either the stop control or a jumper MUST be wired between
terminals 4 and 5 for the push buttons to function.
