CLUTCH ADJUSTMENT AND AUXILIARY REVERSAL SYSTEM
1. Remove cotterpin from nut on the clutch shaft.
2. Back off clutch nut until there is very little tension
on the clutch spring.
3. Tighten clutch nut gradually until there is just
enough tension to permit the operator to move the
door smoothly but to allow the clutch to slip if the door
is obstructed. When the clutch is properly adjusted, it
should generally be possible to stop the door by hand
during travel.
4. Reinstall Cotterpin.
The Auxiliary Reversal System works in tandem
with the adjustable clutch to detect if a closing door
meets an obstruction. If an obstruction is met and
causes the clutch to slip, the Auxiliary Reversal
System will return the door to the full open position.
The Auxiliary Reversal System is designed to protect
the door and motorized operator. It is not intended as
a replacement for a safety sensing device, nor will it
work for sectional doors when a jackshaft operator is
used.
CAUTION: The adjustable friction clutch is NOT
an automatic reversing device. An electric or
pneumatic reversing edge can be added to bottom edge of door if desired.

RPM Sensor/Auxiliary Reversal System (Programming is Recommended)
Feature:By programming the RPM sensor to a specific application, the logic
board learns the speed the door travels with reference to the spinning motor.
This sensor activates the start winding and recognizes clutch slippage.
Benefit:By removing the centrifugal start switch from 1/3 and 1/2 horsepower single-phase motors the leading cause of motor failure is eliminated.
The auxiliary reversing benefits of the RPM sensor are designed to prevent
excessive door and operator damage upon hitting a solid obstruction.
LiftMaster recommends the use of safety devices for primary safety protection.
To Program:
1. The open and close limits must be set before setting the RPM sensor.
2. Start with the door closed and turn all dip-switches to the off position.
3. Press open then press and hold the "learn" button on the Logic board until
the door reaches the full open position. You should see the Learn LED turn off
after pressing the learn button; it will turn back on about 5 seconds
later. If the LED did not cycle, start over and wait about ¼ to ½ second
between pressing "open" and "learn".
4. Return the dip switches to your regular wiring type (C2, B2, etc.) and close
the door.
Note:LiftMaster 2.0 Logic operators are designed to work in most cases
without adjusting the RPM sensor. It is still recommended to set this feature
on every installation. This feature will need to be reset if the motor or logic
board is ever replaced.
Maximum Run Timer (Setting is Recommended)
Feature:The door will run in one direction for a set amount of time. Default
time is 90 seconds. Installer can adjust the 90 second timer to the open cycle
plus 10 seconds.
Benefit:Should the door hit an obstruction that is not detected by a sensor,
it will stop after the programmed amount of time and not continue to drive into
the obstruction. This may help prevent prolonged human entrapment as well
as help prevent damage to the door and operator .
To Program:
art with the door closed and the limits set.
1. St
2. Set the dip switches to "set Max Run Timer".
3. Press Open and wait for the door to reach the full open limit.
4. Return the dip switches to the desired wiring type (C2, B2, etc.) and Close
the door
. The Maximum Run Timer is now set and will allow the door to move
in one direction no more than 10 seconds longer than it normally takes to travel from close to open.
Example: If it takes the door 13 seconds to open normally, the operator will
stop running after 23 seconds. If the Max Run
Timer is not programmed, it will
run for 90 seconds total in either direction.
Note:For very large, slow moving doors, where the normal travel time is
close to 90 seconds setting the MRTis essential to move the door the full travel distance.

feature is optional. By default, this feature will never activate.
Benefit:The consumer will be aware of when it is time for a scheduled maintenance 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.
pecial Notes about the MAS: A5th wire must be run to the control station
S
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

attached: CPS-L, CPS-LN4, CPSII, CPSII-N4. When running, the dip switches must be set for TS, T, or FSTS. See red/green warning light instructions
for further details.
Timer To Close
Feature:Installer can set a timer to automatically close after a preset amount
of time once all safety devices are unobstructed.
Benefits: Door will automatically close after being used. Extremely convenient where users may not be concerned with closing the door. For example
Apartment Buildings and Fire Stations.
Requirements: Must have at least one of the following safety devices
attached: CPS-L, CPS-LN4, CPSII, CPSII-N4. When running, the dip switches
must be set for TS, T, or FSTS

1. Close the door.
2. Set dip switches to "Set Timer To Close"
3. Press "close" to zero out the timer.
4. Press "open" for every 5 seconds seconds the operator should wait before
attempting to close the door.
Example: The door is supposed to close 30 seconds after the user drives
through. To set the TTC for 30 seconds press close, then open 6
times.
5. Return the dip switches to the desired wiring type. TS, T, or FSTS
Notes: For longer delay time settings, use the Single Button Control (terminal
1) to add 1 minute at a time. To deactivate the timer press stop. The timer will
be reactivated on the next operation command.
Reminders: FSTS wiring mode allows the Timer To Close to be activated by
the Single Button Control (terminal 1) only. T wiring mode allows the door to
attempt to close only one time for safety purposes.

TROUBLE SHOOTING

Diagnostic Checklist Procedure
1. Look for the 3 Green LEDs
A. If the 24 VAC light is out, check the transformer and any interlock switches, then replace either the
transformer or the logic board.
B. If the 5 VDC light is out, and the 24VAC is lit, replace the board.
C. If the Stop Button light is out, check the wiring to the control station, if the site does not require a stop
button use a jumper across terminals 4 and 5. If the LED is still not lit call for more assistance.
2. Check your control station:
A. Place the operator into diagnostic mode (all DIP switches ON)
B. Watch the LEDs as each control button is pressed. The LEDs should light with each Open, Close, and
Single Button Control command. The Stop should turn off the LED.
3. Activate the limit switches to verify functionality. Also watch the LED's during door travel to check for over
active limit switches.
4. Disconnect all devices and reattach them one at a time testing for failure after each item is replaced. This will
determine which device is causing the failure. For further assistance call for technical support.
STEP 3: Relearn RPM. Because factory default is set without a door attached to the operator, factory default set-
ting is not a preferred status.
1. Start with the door closed and set all Dip switches to the off position.
2. Press open then press and hold the "learn" button on the Logic board (see picture) until the door reaches the
full open position. You should see the Learn LED turn off after pressing the learn button; it will turn back on
about 5 seconds later. If the LED did not cycle, start over and wait about ¼ to ½ second between pressing
"open" and "learn".
3. Return the dip switches to your regular wiring mode and close the door.
Diagnostic LEDs
There should always be 3 green LEDs activated (24 VAC, 5 VDC, and STOP Button). Check for this first then proceed to check the status of the remaining LEDs
STEP 2: To "unlearn" the photo eyes. The latest software automatically learns if direct connect photo eyes
(CPS-L or CPS-LN4) are attached during the first open cycle of operation. If they are disconnected at some point
after this, they must be unlearned.
1. Set the dip switches to set Timer To Close.
2. Press Open 2 times then Close 2 times and then Stop 2 times (order is not specific).
3. Return the dip switches to the desired wiring type.
