Programming-Introduction to programming
LOGIC BOARD OVERVIEW
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 have door
control at the electrical box.
Either the stop control or a jumper MUST be wired between
terminals 4 and 5 for the on board push buttons to function.
NOTE: 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). Refer to page 19 for limit switch adjustment instructions.
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 LED OVERVIEW
Many programmable functions require that a LiftMaster
Entrapment Protection (LMEP) device be installed in order to
function. Refer to the Entrapment Protection section.
