Maintenance Alert System (Mas) - LiftMaster Logic 5.0 GSD Mode D'emploi

MAINTENANCE ALERT SYSTEM (MAS)

Feature: An internal cycle counter will activate a flashing LED on
the 3-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. Logic 5.0
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: The Maintenance Alert System (MAS) assists the
installing dealer in setting up a routine maintenance program.
Once programmed, the MAS notifies the end user (with a flashing
LED on the 3-button station) when a preset number of cycles/
months has elapsed and scheduled maintenance is due.
To Program:
1. Close the door.
2. Turn the selector dial to PROG.
3. Press and release the MAS SET button.
4. Press the STOP button once to clear the MAS memory.
5. Press the OPEN button once for every 5,000 cycles increments.
Press the CLOSE button once for every 3 month increments.
6. Press and release the MAS button to complete the
programming. The on board LED will flash back the
programmed settings. The OPEN LED will flash once for every
5,000 cycles. The CLOSE LED will flash once for every 3
months.
7. Turn the selector dial back to the 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 29 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
PROG, press MAS button, press the STOP button to clear the
memory and then press the OPEN button 6 times (30,000 cycles)
and the CLOSE button 4 times (12 months). Press the MAS again
to complete the programming. Turn the selector dial back 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 logic 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 DIAG 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 DIAG 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. Turn the selector dial
back to desired wiring type.
