LiftMaster Operator Alarm Instruction Manual

LiftMaster Operator Alarm

OPERATION

Operator Alarm
When the inherent force of the operator detects the following twice consecutively, the alarm will sound up to 5 minutes and the operator will need to be reset.

• A. The gate is hitting an obstruction.
• B. The gate does not meet specifications.
• C. Debris is on the gate’s track such as mud, rocks, dirt, etc.
• D. The gate has one or more broken axles or wheels.
• E. The gate wheel is off the gate rail.

The operator alarm will beep 3 times with a command if the battery is low.
Remove any obstructions or repair gate system. Press the reset button to shut off the alarm and reset the operator. After the operator is reset, normal functions will resume.

Remote control

here are 3 different options for programming the remote control depending on how you would like the remote control to function, see page 24.

Single Button Open Only
When gate is in the closed position, activation of the remote control button will open the gate. The Timer-to-Close can be set to close the gate.

Single Button Control (SBC) Functionality
Program one remote control button as an open, close, and stop
When gate is in the closed position, activation of the remote control button will open the gate. During the open cycle another activation of the remote control will stop the gate and the next activation of the remote control will close the gate.
When the gate is in the open position, activation of the remote control button will close the gate. If the remote control is activated while the gate is closing, the gate will stop and the next activation will open the gate.

Three Button Remote Control
Program each remote control button as an open, close, and stop.

ACCESSORY WIRING

All control wiring used to connect external devices to Class 2 circuits of the operator must be (QPTZ) Power-Limited Circuit Cables, Type CL2, CL2P, CL2R, or CL2X or other cable with equivalent or better electrical, mechanical, and flammability ratings.

External Control Devices

NOT TO BE USED AS ENTRAPMENT PROTECTION
EXIT (2 Terminals)
This input is a soft open command (maintained switch does not override external safeties and does not reset alarm condition). Used for exit probe, telephone entry, external exit loop detector, or any device that would command the gate to open.

• Opens a closed or closing gate and holds open an open gate, if maintained, pauses Timer-to-Close at OPEN limit.

SHADOW (2 Terminals)

This input is used for external shadow loop detector when loop is positioned under the swing of the gate.

• Holds open gate at open limit
• Only active when the gate is at the OPEN limit, disregarded at all other times
• Pauses Timer-to-Close at OPEN limit

INTERRUPT (2 Terminals)

This input is used for an external interrupt loop detector when loop is on the outside of the gate.

• Holds open gate at open limit
• Stops and reverses a closing gate to open limit
• Pauses Timer-to-Close at OPEN limit, activates quick close and anti-tailgate features when enabled on the expansion board

Locks

Maglock (2 Terminals, N.C. and COM)
Relay contact output, Normally – closed (N.C.) output for maglocks. Relay activates prior to motor activation and during motor run. Relay is off when motor is off.

Miscellaneous Wiring

Three button control station (4 Terminals)

• OPEN and COM: Opens a closed gate. Hard open (maintained switch overrides external safeties and resets alarm condition). If maintained, pauses Timer-to-Close at OPEN limit. Opens a closing gate and holds open an open gate (within line-of-sight).
• CLOSE and COM: Closes an open gate. Hard close (maintained switch overrides external safeties and resets alarm condition within line-of-sight) STOP and COM: Stops a moving gate. Hard stop (maintained switch overrides
• Open and Close commands and resets alarm condition). If maintained, pauses Timer-to-Close at OPEN limit. Overrides Open and Close commands (within line-of-sight).

Fire department open input (2 Terminals)

Acts as hard open.
Maintained input overrides (ignores) external safeties (photoelectric sensor and edge), pauses Timer-to-Close momentary input logic as single button control and safeties remain active, re-enables Timer-to-Close.

Accessory power class 2 supply 24 VDC, MAX 1 Amp (4 Terminals)

• SWITCHED: Switched ON with gate motion and at the open limit when Timer-to-Close is active. Turns off 5 seconds after motion.
• UNSWITCHED: 24 Vdc voltage out to power accessories, always ON.

Terminal Block

The terminal block provides additional space for accessory wiring.

EXPANSION AND RELAY ADAPTER BOARDS

CAUTION

To AVOID damaging the circuit board, relays or accessories, DO NOT connect more than 42 Vdc (32 Vac) to the AUX relay contact terminal blocks.

Expansion and Relay Adapter Boards Overview

1. QUICK CLOSE switch:
   OFF: No change to the gate’s normal operation.
   ON: When CLOSE EYES/Interrupt loop is deactivated it causes an opening or a stopped gate to close (ignores the Timer-to-Close).

2. AC FAIL switch:
   OPEN: Loss of AC power will cause the gate to open approximately 15 seconds after AC power fail and remain OPEN until AC power is restored (enabling the Timer-to-Close).
   BATT: With loss of AC power, gate will remain in present position and operator is powered from batteries.

3. EXIT FAIL switch:
   When set to OPEN, if the EXIT plug-in loop detector (Model LOOPDETLM) detects a fault, then the gate will open and remain open until fault is cleared. When set to CLOSE, then plug-in EXIT loop detector faults are ignored (EXIT loop is faulted and inoperative).

4. ANTI-TAIL switch:
   OFF: When CLOSE EYES/Interrupt loop is activated it causes a closing gate to stop and reverse.
   ON: When CLOSE EYES/Interrupt loop is activated it causes a closing gate to pause. Once the vehicle is clear the gate will continue to close.

5. AUX RELAY switches:
   Set the AUX RELAY switches as needed to obtain the desired function as shown on the following page.

6. EYE/EDGE switches:
   Set the EYE/EDGE switches as needed to obtain the desired OPEN or CLOSE functionality.

7. 1, 2, and 3 LEDs:
   LEDs indicating the status of the EYE/EDGE inputs. Also used to check the firmware version of the expansion board:

8. Locate the 1, 2, and 3 LEDs on the expansion board.

9. Disconnect AC/DC power to the control board for 15 seconds.

10. Connect power. The 1, 2, and 3 LEDs will flash in sequence until the control board firmware revision is displayed. When the green POWER LED glows solid the LED 1 will flash the version number, then stop, then the LED 2 will flash the revision number (for example: For version 5.1 when the green POWER LED is solid the LED 1 will flash 5 times, then stop, then the LED 2 will flash once).

11. J6 and J7 inputs:
    Communication bus connects control board, expansion board, or relay adapter board. Also connects LiftMaster wireless edge receiver LMWEKITU. NOTE: ONLY one wireless edge receiver may be connected to an operator. Up to 4 wireless edge transmitters LMWETXU may be programmed to the receiver.

12. Input LEDs:
    LEDs indicating the status of the SBC, OPN, CLS, and STP inputs.

13. Loop detector inputs:
    Inputs for the Plug-In Loop Detectors (Model LOOPDETLM)

Auxiliary Relays

The expansion board and relay adapter board provide Normally Open (N.O.) and Normally Closed (N.C.) relay contacts to control external devices, for connection of Class 2, low voltage (42 Vdc [34 Vac] max 5 Amps) power sources only. Function of relay contact activation determined by switch settings.

stored on the control board). See below.

| Red/green light functionality, see below.

Cycle count

First, note the current Aux Relay switch positions. To determine the actual cycles that the gate operator has run (in thousands), set all three Aux Relay switches to the ON setting for Aux Relay 1. The Expansion Board’s 1, 2, and 3 LEDs will blink out the cycle count, with 1 LED blinking 1000’s, 2 LED blinking 10,000’s, 3 LED blinking 100,000’s, and simultaneously all three LED’s blink 1,000,000’s (e.g. 1 LED blinks 3 times, 2 LED blinks 6 times, and 3 LED blinks once. Cycle count is 163,000.). Cycle count displayed is between 1,000 and 9,999,000 cycles. After servicing, set Aux Relay switches back to their appropriate positions. Cycle count cannot be reset or changed. If under 1,000 cycles the 1, 2, and 3 LEDs will turn on for 10 seconds, then turn off.
NOTE: The expansion board will flash the cycle count 3 times then all the LEDs will turn on solid for 10 seconds then turn off.

MAINTENANCE

IMPORTANT SAFETY INSTRUCTIONS

WARNING

• To reduce the risk of SEVERE INJURY or DEATH:
• READ AND FOLLOW ALL INSTRUCTIONS.
• ANY maintenance to the operator or in the area near the operator MUST NOT be performed until disconnecting the electrical power (AC or solar and battery) and locking-out the power via the operator power switch. Upon completion of maintenance the area MUST be cleared and secured, at that time the unit may be returned to service.
• Disconnect power at the fuse box BEFORE proceeding. Operator MUST be properly grounded and connected in accordance with national and local electrical codes. NOTE: The operator should be on a separate fused line of adequate capacity.
• NEVER let children operate or play with gate controls. Keep the remote control away from children.
• ALWAYS keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF THE MOVING GATE.
• The entrance is for vehicles ONLY. Pedestrians MUST use separate entrance.
• TEST THE GATE OPERATOR MONTHLY. The gate MUST reverse on contact with an object or reverse when an object activates the noncontact sensors. After adjusting the force, speed, or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly can increase the risk of INJURY or DEATH.
• Use the manual disconnect release ONLY when the gate is NOT moving.
• KEEP GATES PROPERLY MAINTAINED. Read this manual carefully. Have a qualified service person make repairs to gate hardware.
• ALL maintenance MUST be performed by a Trained Gate Systems Technician.
• Activate gate ONLY when it can be seen clearly, is properly adjusted and there are no obstructions to gate travel.
• To reduce the risk of FIRE or INJURY to persons use ONLY LiftMaster part 29-NP712 for replacement batteries.
• SAVE THESE INSTRUCTIONS.

CAUTION
ALWAYS wear protective gloves and eye protection when changing the battery or working around the battery compartment.

Maintenance Chart

Disconnect all power (AC, solar, battery) to the operator before servicing.

NOTES:

• High cycle usage may require more frequent maintenance checks.
• Limits may have to be reset after any major drive chain adjustments.
• If lubricating chain, use only lithium spray. Never use grease or silicone spray.
• It is suggested that while at the site voltage readings be taken at the operator. Using a digital voltmeter, verify that the incoming voltage to the operator is within ten percent of the operator’s rating.

Batteries

Batteries will degrade over time depending on temperature and usage. The operator alarm will beep 3 times with a command if the battery is low. Batteries do not perform well in extremely cold temperatures. For best performance, the batteries should be replaced every 3 years. Use only LiftMaster part 29-NP712 for replacement batteries. The batteries contain lead and need to be disposed of properly.
The operator comes with two 7AH batteries. Two 33AH batteries
(A12330SGLPK), with battery harness model K41-0102-000 (not provided), may be used in place of the 7AH batteries.

Drive Train

Over time, the drive chain on the operator will stretch and need to be tightened. To tighten the drive chain adjust either of the two chain eye bolts. NOTE: The chain should have no more than 1 inch of sag for every 10 feet of chain length.

Position
The location of the panel(s) is critical to the success of the installation. In general, the panel(s) should be mounted using the provided angle bracket facing due south. The solar panel(s) should be mounted in an area clear of all obstructions and shade from buildings and trees. If the panel(s) is not casting a shadow, the battery is not being charged.
NOTE: Tall trees or buildings that do not shade the solar panel(s) in the summer could shade the solar panel(s) during the winter months when the sun sits lower in the sky.
