INSTALLATION MANUAL VEHICULAR SLIDE GATE OPERATOR
OPERATION
Control Board Overview
1 SET OPEN Button: The SET OPEN button sets the OPEN limit. See Adjustment section.
2 SET CLOSE Button: The SET CLOSE button sets the CLOSE limit. See Adjustment section.
3 DIAGNOSTICS Display: The diagnostics display will show the operator type, firmware version, and codes. The operator type will display as "HL" followed by a "24" which indicates the operator type as HDSL24UL. The firmware version will show after the operator type, example "1.2".
4 BATT FAIL:
- When AC power is OFF and battery voltage is critically low the gate will latch at a limit until AC power is restored or batteries voltage increases.
- Option select switch set to OPEN forces gate to automatically open and then latch at the OPEN limit until AC power is restored or battery voltage increases.
- Option select switch set to CLOSE forces gate to latch at CLOSE limit if at CLOSE limit or on next CLOSE command until AC power restored or battery voltage increases.
- Constant pressure on a hard command input overrides to open or close the gate.
- Critically low battery is less than 23 Vdc.
5 BIPART DELAY Switch: The LOCK/BIPART DELAY switch is used only for dual gates. See Bipart delay/synchronized closed page 21.
6 LEARN Button: The LEARN button is for programming remote controls and the network.
7 TEST BUTTONS: The TEST BUTTONS will operate the gate (OPEN, STOP and CLOSE).
8 MOVE GATE Buttons: The MOVE GATE buttons will either open or close the gate when the operator is in Limit setting mode. See Adjustment section.
9 SPEED CONTROL dial: Sets maximum gate speed, see Speed Control page 24.
10 TIMER-TO-CLOSE dial: The TIMER-TO-CLOSE (TTC) dial can be set to automatically close the gate after a specified time period. The TTC is factory set to OFF. If the TTC is set to the OFF position, then the gate will remain open until the operator receives another command from a control. Rotate the TIMERTO-CLOSE dial to the desired setting. The range is 0 to 180 seconds, 0 seconds is OFF. NOTE: Any radio command, single button control, or CLOSE command on the control board prior to the TTC expiring will close the gate. The TTC is reset by any signals from the open controls, loops, close edges, and close photoelectric sensors (IR’s).
11 REVERSAL FORCE dial: The REVERSAL FORCE dial fine tunes the force, see Fine Tune the Force page 24.
12 STATUS LEDs: The STATUS LEDs indicate the status of the operator. See Status LED Chart in the Troubleshooting section.
Manual Disconnect
- Set the reset switch to the RESET position.
- Pull the manual release handle.
To resume normal function, release the handle and set the switch to NORMAL OPERATION. On a dual gate application the handle must be released on both operators.
Reset Switch
The reset switch has the following functions:
- Set the switch to the RESET position to disable gate operation. Use this switch before servicing the gate or manually disconnecting the gate. The stop LED will be illuminated.
- To hold the gate open, run the gate to the open position and then set the switch to the RESET position.
- Toggle the reset switch to RESET then back to NORMAL OPERATION when the operator alarm has been set off, see page 32.
- To put the operator into high band programming mode, give the operator an OPEN command. Within 30 seconds, when the gate is at the open limit, toggle the reset switch between RESET and NORMAL OPERATION three times.
Relay Adapter Board and Terminal Block Access
To access the relay adapter board and terminal block, loosen the two screws of the control board bracket, slide the whole bracket to the right, then swing open.
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. Toggle the reset switch to RESET then back to NORMAL OPERATION to shut off the alarm and reset the operator. After the operator is reset, normal functions will resume. |

Remote control
There are 3 different options for programming the remote control depending on how you would like the remote control to function, see page 26.
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.
MAINTENANCE
Maintenance Chart
Disconnect all power (AC, solar, battery) to the operator before servicing.
NOTES:
- 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.
33AH batteries are NOT compatible if transformer kit model 3PHCONV is installed.
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.
