It is imperative that the wall or mounting surface provide adequate

support for the operator.

This surface must:

a. Be rigid to prevent play between the operator and the door

shaft.

b. Provide a level base.

c. Permit the operator to be fastened securely and with the drive

shaft parallel to the door shaft.

To prevent possible SERIOUS INJURY or DEATH:

• DO NOT connect electric power until instructed to do so.

• If the door lock needs to remain functional, install an interlock

switch.

• ALWAYS call a trained door systems technician if door binds,

sticks or is out of balance. An unbalanced door may NOT

reverse when required.

• NEVER try to loosen, move or adjust doors, door springs,

cable, pulleys, brackets or their hardware, ALL of which are

IMPORTANT INFORMATION ABOUT THE LIFTMASTER

MONITORED ENTRAPMENT PROTECTION DEVICES

A LiftMaster Monitored Entrapment Protection (LMEP) device is

required for most wiring types (refer to page 29). The operator

comes standard with the photoelectric sensors model CPS-U,

additional entrapment devices are available for purchase

(see accessories). If a LiftMaster Monitored Entrapment Protection

device is not installed, constant pressure to close will be required

from the control station.

When properly connected and aligned, the photoelectric sensors

will detect an obstruction in the path of its invisible light beam. If

an obstruction breaks the light beam while the door is closing, the

door will stop and typically reverse to the full open position.

The photoelectric sensors must be installed facing each other

across the door, no more than 6" (15 cm) above the floor.

Each photoelectric sensor has an LED that will glow steady when

the sensor is properly connected and aligned. The LEDs on both

photoelectric sensors will flicker rapidly when obstructed or

misaligned.

AUXILIARY REVERSAL SYSTEM / RPM SENSOR

The Auxiliary Reversal System is designed to protect the door

and motorized operator. It is NOT a substitute for a safety sensing

device.

Feature: This feature utilizes the RPM sensor connected to the logic

board to detect when the clutch slips and reverses the door (clutch

must be properly adjusted). In addition, the RPM eliminates the

need for a centrifugal switch on single phase motors.

Benefit: The Auxiliary Reversal System reverses the operator upon

hitting an obstruction, preventing excessive door and operator

damage. We require the use of safety devices for primary safety

protection. By removing the centrifugal switch on single phase

motors, the leading cause of motor failures is eliminated. (Auxiliary

Reversal System not applicable on models GH and GT.)

NOTE: This feature is automatically learned and does not require

programming.

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.

Loosen set screws of torque adjustment nut on the gear

reducer.

Back off torque nut until there is very little tension on the

belleville washers.

Tighten torque nut gradually until there is just enough tension

LOGIC BOARD OVERVIEW

LOGIC BOARD PUSH BUTTONS (OPEN, CLOSE, STOP)

Open, Close and Stop buttons are mounted directly on the logic

board. Thus, making it easy to program as well as have 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.

NOTE: Before programming the logic board, set the operator’s

open and close limits. LEDs on the logic board are provided to

assist setting the limits. As each limit is activated the

corresponding LED will light up. The abbreviations are Open Limit

Switch (OLS), Close Limit Switch (CLS) and Sensing Limit Switch

(SLS). Refer to page 19 for limit switch adjustment instructions.

When power is applied to the operator, the following LED’s will

illuminate: STOP, CLOSE, OPEN, LMEP, 24Vac, RADIO, DATA,

TIMER ENABLE, OLS MID, SLS, CLS, and MAS. Once the power

up process is completed (approximately 2-3 seconds) only the

appropriate LED’s will continue to be lit (i.e., STOP, 24Vdc, limit

LED(s) if limit(s) is activated).

NOTE: When the power up process is over, the MAS LED will

blink a code indicating the version of firmware. If the selector

dial is in the DIAG, OPTN, or PROG position, the MAS will not

provide this code. After the code has been provided the MAS LED

will go out.

LOGIC BOARD LED OVERVIEW

Troubleshooting guide

TROUBLESHOOTING

TROUBLESHOOTING ERROR CODES

Logic 4.0 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.

If the MAS LED is flashing on and off rapidly, the Maintenance

Alert System has been triggered and the schedule operator service

is due. If the MAS LED flashes 2 or more pulses in a row followed

by a pause, an operator error has occurred. To view how many

errors currently exist, turn the selector dial to DIAGNOSTIC and

press the OPEN button. To read out each individual error code

(if more than one exists) press CLOSE. It is possible to have more

than one error at a time.

The chart below can assist with identifying the flashes on the

MAS LED.

NOTE: Error codes take priority over normal MAS LED operation. Error codes will repeat on the MAS every 1.5 seconds until cleared.

There may be more than one error present, but only the highest priority will flash. If the highest error is cleared, the next highest will

flash. All errors self-correct when the corrective action is taken and a reset is not needed.
