Maintenance Alert System; Optional Programming; Mid Stop - Chamberlain H Owner's Manual

STANDARD PROGRAMMING FEATURES CONT'D
MAS (Maintenance Alert System)
Feature: An internal cycle counter will activate a flashing LED on the three-
button control station when the preset number of cycles is reached. Setting this
feature is optional. By default, this feature will never activate.
Benefit: The consumer will be aware of when it is time for a scheduled main-
tenance on the door or operator.
To Program:
1. Close the door.
2. Set the dip switches to "set Maintenance Alert System"
3. Press "close" to zero out the counter.
4. Press "open" for every 5,000 cycles the operator should wait before
flashing the LED.
5. Return the dip switches to your regular wiring type (C2, B2, etc.) and close
the door.
EXAMPLE: The door is being installed with 30 thousand cycle springs. To set
the MAS for 30,000 cycles press close, then open 6 times. Return the dip
switches to the desired wiring type.
Special Notes about the MAS: A 5th wire must be run to the control station
to activate the MAS LED. When the operator is serviced after the MAS has
started the LED flashing, repeat the setup procedure for the next service visit.
To see how many cycles the operator has been through set the dip switches to
"set MAS" and watch the MAS led. It will flash once for every 1000 cycles the
operator has been used then pause and repeat. Every time the operator leaves
the close limit is counted as one cycle.

Mid Stop

Feature: Door will open to an installer set height that is less than fully open.
Benefit: The door will not open fully which will reduce unwanted airflow
through the doorway. The door will not cycle fully providing longer door and
operator life.
To Program:
1. Close the door.
2. Set dip switches to "set mid stop".
3. Press open (the door will begin moving)
4. Press stop when the desired mid stop height is reached.
5. Return the dip switches to the desired wiring type (C2,B2,etc.). The door will
now stop at this height every time the door is opened.
Notes: A momentary open command will open the door fully from the mid
stop position. Photo eyes and other safety devices will not further open the
door from the mid stop position. Timer To Close will work from the mid stop
position.
