Maintenance Alert System (Mas) - Chamberlain J Owner's Manual

MAINTENANCE ALERT SYSTEM (MAS)

Feature: An internal cycle counter will activate a flashing LED on
the three button control station when the preset number of cycles
or months has elapsed (whichever occurs first). Setting this
feature is optional. By default this feature will never activate.
LiftMaster Logic 3.0 operators incorporate a self diagnostic
feature built into the MAS LED. In addition to indicating when
routine maintenance is due, the MAS LED can be used to
troubleshoot some problems with the operator.
Benefit: Notifies the end user when scheduled maintenance is
due. Assists the installing dealer in setting up a routine
maintenance program.
To Program:
1. Start with the door in the closed position
2. Turn the selector dial to PROGRAM
3. Press the MAS button on the logic control board
4. Press the STOP button to zero out the MAS counter
5. Press the OPEN button for every 5,000 cycles the operator
should wait before flashing the MAS LED and Press the
CLOSE button for every three months the operator should wait
before flashing the MAS LED.
6. Press MAS to confirm setting. The OPEN LED will flash once
for every 5,000 cycles programmed and the CLOSE LED will
flash once for every 3 months programmed.
7. Set selector dial back to desired wiring type.
NOTE: If MAS LED flashes 2 or more flashes in a row followed by
a pause, an operator error occurred. Turn to page 27 to diagnose
problem.
Example: A door is installed with 30,000 cycle springs and has
an annual service contract. To set the MAS, turn selector dial to
PROGRAM, press MAS button, press the STOP button to clear
the memory and then press the OPEN button 6 times (30,000
cycles) and close 4 times (12 months). Press the MAS again to
complete the programming. Set the selector dial to desired wiring
type.
Special Notes about MAS: A 5th wire must be run to the control
station to activate the MAS LED. The MAS LED on the control
board is always enabled. When the operator is serviced after the
MAS LED has started to flash, repeat the setup procedure to
program in the number or cycles desired until the next service
visit OR press and hold the MAS button for 5 seconds in the
PROGRAM mode to reset the MAS with its current programmed
value. To disable the MAS, follow the programming procedure
above and press the STOP button to reset the counter to zero.
Every time the operator leaves the close limit is counted as one
cycle.
To view how many cycles are programmed into the MAS, set the
selector dial to DIAGNOSTIC and press the MAS button. The
OPEN button LED will flash once for every 5,000 cycle increment
programmed and the CLOSE button LED will flash once for every
3 month increment programmed.
To view how many cycles have elapsed since the last time the
MAS was programmed, set the selector dial to "Diagnostic" and
press the "MAS" button. Press the OPEN button; the OPEN LED
will flash once for every 5,000 cycles that has elapsed. Press the
CLOSE button; the CLOSE LED will flash once for every (3)
months that has elapsed. Press the MAS button to exit.
