Page 3 BEFORE YOU BEGIN UL COMPLIANT GATE OPERATORS The UL standard requires gate operators to monitor for the presence of external entrapment devices and any fault conditions. LiftMaster has not only updated their line of gate operators to meet the new UL 325 standard, they have also taken the opportunity to add a common user interface and common feature sets across the line to increase performance, safety and accessibility.
Page 4 BASIC TROUBLESHOOTING MULTI-METERS The image is an example of a generic multimeter. LiftMaster currently has no intended affiliations with this multi-meter manufacturer. This is not an endorsement for this particular meter model. When shopping for a meter, look for a meter able to fit in a shirt pocket or clip on a belt.

Page 6 BASIC TROUBLESHOOTING RELAYS EXPANSION BOARD RELAYS In gate operators, relays are commonly used to control operator functions or activate/deactivate ancillary devices such as heaters or lights. When electricity is applied to a relay coil, it energizes a magnetic field that will close a Normally Open switch or open a Normally Closed switch. A relay typically has prongs labeled COM , NO, NC, and two prongs to power the relay coil.
Page 7 BASIC TROUBLESHOOTING To protect against fire and electrocution: • DISCONNECT power (AC or solar and battery) BEFORE installing or servicing operator. CAPACITOR (FOR AC OPERATORS) SYMPTOM: A bad capacitor will cause a motor to hum when trying to run, or stall while it is running. CHECK THE CAPACITOR: Disconnect ALL power from operator.

Page 9 BASIC TROUBLESHOOTING To protect against fire and electrocution: • DISCONNECT power (AC or solar and battery) BEFORE installing or servicing operator. AC MOTORS SYMPTOM: The motor will not run. CHECK THE MOTOR: Disconnect ALL power from operator. Disconnect the gate from the operator. Unplug the motor harness from the board and measure the resistance of the motor.
Page 10 BASIC TROUBLESHOOTING ERASE MEMORY ERASE ALL REMOTE CONTROLS 1. Press and release the LEARN button (operator will beep and green XMITTER LED will light). 2. Press and hold the LEARN button again until the green XMITTER LED flashes and then release the button (approximately 6 seconds). All remote control codes are now erased.
Page 11 BASIC TROUBLESHOOTING PROGRAMMING LIMITS WITH BUTTONS AND REMOTES For dual gate applications, the limits must be set for each operator. The gate MUST be attached to the operator before setting the limits and force. Ensure the gate is closed. 1. Press and release the SET OPEN and SET CLOSE buttons simultaneously to enter limit setting mode. 2.
Page 12 DIAGNOSTIC CODES To retrieve logic board diagnostic history, the operator must be activated. • Replace ONLY with fuse of same type and rating. For continued protection against fire: DIAGNOSTIC CODES OPEN, CLOSE, & STOP BUTTONS TO VIEW THE CODES DIAGNOSTICS DISPLAY The codes will show on the diagnostic display.
Page 13 DIAGNOSTIC CODES Some codes are saved in the code history and some are not. If a code is not saved it will briefly appear on the display as it occurs, then disappear. When servicing of the operator is complete, erase the code history by pressing the STOP button until the display flashes “Er” then “CL” (about 6 seconds).
Page 14 DIAGNOSTIC CODES Some codes are saved in the code history and some are not. If a code is not saved it will briefly appear on the display as it occurs, then disappear. When servicing of the operator is complete, erase the code history by pressing the STOP button until the display flashes “Er” then “CL” (about 6 seconds).
Page 15 DIAGNOSTIC CODES Some codes are saved in the code history and some are not. If a code is not saved it will briefly appear on the display as it occurs, then disappear. When servicing of the operator is complete, erase the code history by pressing the STOP button until the display flashes “Er” then “CL” (about 6 seconds).
Page 16 DIAGNOSTIC CODES Some codes are saved in the code history and some are not. If a code is not saved it will briefly appear on the display as it occurs, then disappear. When servicing of the operator is complete, erase the code history by pressing the STOP button until the display flashes “Er” then “CL” (about 6 seconds).
Page 17 DIAGNOSTIC CODES Some codes are saved in the code history and some are not. If a code is not saved it will briefly appear on the display as it occurs, then disappear. When servicing of the operator is complete, erase the code history by pressing the STOP button until the display flashes “Er” then “CL” (about 6 seconds).
Page 18 SOLAR SOLAR TROUBLESHOOTING SYMPTOM The operator alarm will beep three times with a command and the BATT LOW LED will be on when the solar panel is not charging the battery. SOLUTIONS • Check that the correct number of solar panels are connected to the operator. 12V operators require one 10W 12V panel up to a maximum of three 10W 12V panels three solar panels wired in parallel.
Page 19 SOLAR 24V APPLICATIONS Disconnect all power (AC, solar, battery) to the operator before servicing. NOTE: 10W 12V solar panels are illustrated in the image below. In normal operation, the voltage across the diode should measure 0.7 VDC. 33AH BATTERIES To “BATT DC POWER” input on control board ITEMS NEEDED FOR 24V APPLICATIONS...
