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.

: Momentary contact to open, close, and stop with open override and Timer To Close. Every device that causes door to open, including a reversing device, activates the Timer To Close. Auxiliary controls can be connected to open input to activate the Timer To Close. If the timer has been activated, the open but­ton and radio control can recycle the timer. The stop button will deactivate the Timer To Close until the next command input. The Timer To Close will function from the programmable mid-stop with this wiring type. (NOTE: Requires
Optional self monitoring photo eyes to operate.)
Logic Control Pushbuttons Open, Close, Stop
Open, Close and Stop buttons are mounted directly on the Logic Control board. This will provide easy programming ability and 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.

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.

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.

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.
