LCN ELECTRIC AUTO-EQUALIZER 4630

The LCN 4630/4640 Electric Auto-Equalizer Series is a versatile, low-energy door operator designed to combine all door operator and control functions into a single, easy-to-install package. This series is non-handed and non-sized, offering features typically found in heavy-duty LCN door closers, including independent adjustment of backcheck, main speed, and latch speed, as well as adjustable closing power. The units are shipped with LCN's "Ultra X" all-weather hydraulic fluid, ensuring reliable operation across a wide range of temperatures.

Function Description:

The 4600 Series electric Auto-Equalizer provides power opening for interior doors up to 90 degrees. For exterior doors, it must be mounted on the inside only. Manual opening is possible up to 170 degrees for the 4630 model and up to 100 degrees for the 4640 model. The operator is designed to be fail-safe, meaning it acts as a standard door closer in the event of a power outage. As a low-energy operator, it does not require guard rails or safety mats, simplifying installation and reducing overall costs.

Important Technical Specifications:

Protection: Features a circuit breaker and resettable fuses for high-voltage inputs and low-voltage output circuits.
Overall Operator Size: 33 1/2" x 4 3/8" x 5 3/16".

Usage Features:

The 4600 Series offers advanced control and adjustment capabilities through its easy-to-install controller module.

Adjustable Settings:
- Door Opening Speed: Controls how quickly the door opens. Maximum adjustment ensures compliance with ANSI 156.19 specifications. Slower speeds are recommended for heavy doors or strong backcheck settings.
- Door Opening Force: Adjusts the force the door exerts when opening (max 15 lbs). Proper adjustment prevents clutch slippage and motor overpower.
- Hold Open Time: Determines how long the door stays open after reaching the 90° position.
- Alternate Action Timeout: Sets the time the door remains open after an alternate action input, providing an automatic second input to close the door if no further input is received.
- Delay / Trigger Time for Sequential Option: Controls the time between the first and second door activation in sequential door applications.
- Electric Strike Delay Time (E.S. DELAY): Manages the time between an activation signal and actual door movement, allowing electric latching hardware to release.
- 90° Slow Down (90° SLOW DOWN TIME): Adjusts the time from the start of door movement to a transition at approximately 70°, where opening speed is reduced.
- Safety Scanner Lockout Time (LOCKOUT TIME): Controls the duration a safety scanner input is ignored during door closing (only if safety scanners are used).
- One Shot Input (OFF/ON): Determines if hold open delay starts on the last or first activation input signal.
- Exterior Mode (OFF/ON): If off, the door stops and the hold open timer starts upon the first restriction. If on, the door pauses for 1 second on the first restriction (e.g., wind) and then attempts to open again, with the hold open timer starting after the second restriction.
- E.S. 3 Second Power (OFF/ON): Controls whether the E.S. Relay is powered for the entire door open time or only for 3 seconds after activation.
User Interface: Easy access to on/off and hold open switches. The controller features UP and DOWN buttons for adjusting settings, a MODE button to navigate programming setups, a TIME DISPLAY for numeric values, and OPERATING INDICATORS to show internal functions and external hardware status.
Second Chance Feature: If an obstruction is encountered during the opening cycle that exceeds the preset opening force, the controller pauses for one second and then attempts to open the door again.
Automatic Door Decal: Includes "AUTOMATIC CAUTION DOOR" decals to be placed on each side of the door, near the latch area, at 58" (+/- 5") from the floor.

Maintenance Features:

Low Maintenance: The system is designed for low maintenance, requiring no expensive service contracts or periodic maintenance.
Error Codes: The controller performs self-diagnostics and displays error codes (E01-E04) to assist in troubleshooting.
Factory Defaults Reset: The controller settings can be reset to factory defaults by holding down the MODE button while cycling power to the operator.
Controller Removal for Closer Adjustments: For adjustments to door closer regulating screws (main speed, latch speed, backcheck), the controller must be temporarily removed. This involves disconnecting power, unplugging electrical connections, removing a screw, tilting the controller, and disengaging it from mounting pins.
