PROGRAMMING

INTRODUCTION TO PROGRAMMING

Many programmable functions require that a LiftMaster
Entrapment Protection (LMEP) Device be installed in order to
function . Refer to the Entrapment Protection section .
Before programming the logic board, set the operator's open and
close limits. The LEDs on the logic board are provided to assist
setting the limits. Refer to page 23 for limit switch adjustment
instructions.
Apply power to the operator.
When power is applied to the operator, all the LEDs will illuminate
with the exception of SBC, relay A, relay B, and the Timer Defeat.
Once the power up process is completed (approximately 2-3
seconds) only the appropriate LED's will continue to be lit:
Between limits: 24Vac and STOP
Fully closed position: 24Vac, STOP, CLS and SLS
Fully opened position: 24Vac, STOP and OLS
Additional LED's will light when device(s) are activated.
NOTE: When the power up process is completed, 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 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 .
CURRENT SENSING TECHNOLOGY
LOGIC 5.0 3-Phase Operators now include Current Sensing
Technology. The Current Sense Harness is required for operating
LiftMaster Commercial Door Operators that offer this feature. The
Current Sense Feature measures overcurrent and limits operation
under high-current conditions and sends a Diagnostic Error Code
of 12 LED blinks. See Troubleshooting Error Codes section for
more information.
