Usage Guide for Elevator LOP Display Board GR-04-VRA

Correct installation, debugging, and maintenance of the GR-04-VRA LOP display board are crucial to ensuring smooth human-machine interaction and coordinated operation with the door machine pulley system. Nanjing Zhuye Elevatorparts recommends that only certified elevator electrical technicians perform installation and replacement operations.

1. Pre-Installation Preparation

First, confirm that the elevator’s MAC car lighting controller model matches the POWCV24181MH power supply (check parameters such as input voltage, output voltage, output current, and installation dimensions). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and the secondary power supply for the car lighting system, lock the switch, and place a “Maintenance in Progress” warning sign at the elevator landing doors and machine room entrance. Locate the power supply installation position (usually on the car top or in the car control cabinet) and clean the area to remove dust, debris, and oil stains. Finally, prepare professional tools such as a screwdriver, wire stripper, multimeter, and insulation tester, and check that the new POWCV24181MH power supply from Nanjing Zhuye Elevatorparts is intact (no damage to the shell, no loose pins).

First, confirm that the elevator LOP model and control system match the GR-04-VRA display board (check parameters such as interface type, resolution, and communication protocol). Consult Nanjing Zhuye Elevatorparts’ technical team if there is any uncertainty about compatibility. Then, cut off the elevator’s main power supply and LOP power supply, lock the switch, and place a “Maintenance in Progress” warning sign at the landing. Remove the LOP panel from the elevator car wall to expose the internal installation position. Finally, prepare professional tools such as a screwdriver, multimeter, and anti-static gloves; clean the installation slot and connecting terminals, and check the door machine’s drive and driven pulleys for normal operation (abnormal pulley operation may cause fault prompts on the display board).

2. Installation & Wiring

If replacing the old display board, first take photos to record its wiring connections, installation position, and fixing method for later reference. Disconnect the wiring harness from the old display board according to the recorded labels and remove the old display board. Take the new GR-04-VRA display board from Nanjing Zhuye Elevatorparts, insert it into the installation slot (ensure it fits tightly without looseness), and fasten it with fixing screws. Connect the wiring harness to the corresponding terminals strictly following the photos and the wiring diagram provided by Nanjing Zhuye—distinguish between power wires, signal wires, and ground wires to avoid wrong connection. After wiring, use a multimeter to test the power supply voltage to confirm it matches the display board’s rated voltage (consult Nanjing Zhuye’s technical parameters for details).

Debugg3. Operation & Daily Maintenance

Install the LOP panel back to the car wall, restore the power supply, and switch the elevator to inspection mode. Observe the GR-04-VRA display board: it should light up normally, display floor information accurately, and respond promptly to button operations. Test the linkage with the door machine pulley system—press the door open/close button, and the display board should show the corresponding status, while the door machine pulleys operate smoothly. After 1 hour of stable operation, check the display board’s temperature and wiring terminals (no abnormal heat or loose wires). For daily maintenance, inspect the display board during weekly elevator patrols: check if the screen is clear, free of scratches or dead pixels; confirm the panel buttons are sensitive; clean the screen and panel with a soft dry cloth. At the same time, check the door machine pulley system’s operation—abnormal pulley noise or jitter may trigger fault codes on the display board. Every 3 months, recheck the wiring connections; every 6 months, update the display board’s system firmware if necessary (consult Nanjing Zhuye’s technical team for firmware files).

Replacement Cycle of Elevator LOP Display Board GR-04-VRA

The replacement cycle of the GR-04-VRA LOP display board is closely related to operating conditions and the frequency of door machine pulley operation. Under normal circumstances (elevator daily operation 12-24 hours, lobby environment dry and clean, no frequent impact), Nanjing Zhuye Elevatorparts recommends a replacement cycle of 3-5 years. This cycle is determined based on long-term field operation data and component aging tests, fully considering the wear of the LCD screen, button sensitivity attenuation, and circuit board aging.

For elevators in high-traffic areas (e.g., large shopping malls, airports with daily passenger flow exceeding 10,000) or harsh environments (lobby with high humidity, heavy dust, frequent vibration), the replacement cycle should be shortened to 1.5-2 years. High-frequency button operations accelerate button wear, while harsh environments cause screen contamination and circuit board corrosion. For low-usage elevators (e.g., villa elevators, small office buildings with daily operation time < 8 hours) in stable environments, the cycle can be extended to 5-7 years, but only after inspection and confirmation by Nanjing Zhuye’s technicians that the display board’s performance and linkage with the door machine pulley system meet standards.

Replace the display board immediately if any of the following issues occur, regardless of its service life: The screen is severely damaged, blurred, or has a large number of dead pixels affecting information reading; the buttons are insensitive or stuck, failing to transmit operation signals; the display board fails to light up or frequently restarts; it cannot display floor information accurately or respond to the door machine pulley system’s status; the circuit board is burned or corroded, causing frequent elevator fault alarms.
