IMPORTANT NOTE: Before the operator is installed, be sure the door has been properly aligned and is working smoothly. Although each installation will vary due to particular building characteristics, refer to the following gen­eral procedures to install the operator.
MOUNT HEADER BRACKET
The trolley operator is generally mounted over the center of the door. However, off center mounting may be required due to interfering structures or location of door stile / top section support. In such cases, the operator may be mounted up to 24” off center on tor­sion spring doors. Extension springs require center mounting.
1. Locate the center of the door and mark a line on the wall directly above the door. Extend this line up the wall.
2. Determine the highest point of door travel. Slowly raise the door and observe the action of the top sec­tion. When the top section reaches its highest point, use a level and project a line from this point to the center line the of the door.
MOUNT OPERATOR
1. Allowing the motor to rest on the floor, raise the front end of the track assembly to the front header bracket and fasten using the 3/8”dia. x 6.40” long pivot shaft and cotterpins supplied.
3. Using the projected lines for location, mount a suitable wood block or length of angle iron to the wall above the door opening. Refer to the illustration below. This will provide a mounting pad for the front header bracket of the operator. If necessary reinforce the wall with suitable mounting brackets to ensure adequate support of mounting pad. Using suitable hardware, mount the (U shaped) front header bracket to the pad.
Header Bracket Drill Pattern
2. Swing the operator to a horizontal position above the guide rails and temporarily secure with a suitable rope, chain, or support from the floor. Now open garage door slowly, being careful not to dislodge the temporary support. Using the door as a support, place a level against the rail and shim the operator until it is horizontal. Make sure that the operator is aligned with the center line of the door.

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:

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 MRT is essential to move the door the full trav­el distance.

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 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.
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 af 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.

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.
