Monarch Elevator Car 7-Inch LCD Display SFTC-CCB-T7(TS7)-TPJ-YY: High-Definition Interaction for Cab Comfort

Proper Usage Methods of Monarch Elevator Car 7-Inch LCD Display SFTC-CCB-T7(TS7)-TPJ-YY

1. Installation & Commissioning

• First, cut off the elevator power supply and ensure safety. Thoroughly clean the installation position (designated area on the elevator car operation panel or cab wall) to remove dust, oil stains, and debris, ensuring a stable and flat mounting base for the display.
• Place the 7-inch LCD display into the installation slot accurately, ensuring it fits closely with the slot without gaps and is flush with the cab interior surface. Fix the display firmly using matching screws from the back of the installation slot. The tightening torque should comply with Monarch’s technical requirements (typically 2–3 N·m) to avoid damaging the display’s circuit board, screen, or the cab’s decorative panel.
• Correctly connect the wiring: According to the wiring diagram provided by Nanjing Zhuye Elevatorparts and Monarch, connect the display’s power wires (typically DC 12V/24V) and signal wires to the corresponding terminals of the Monarch elevator main controller or car operation panel control board. Ensure the wiring is tight and reliable, and the wire insulation layer is intact to avoid short circuits or poor contact. Pay special attention to the positive and negative poles of the power supply and the correctness of signal line pin connections to prevent damage to the display’s internal circuit module.
• Post-installation commissioning: Restore the elevator power supply, check if the display lights up normally, and verify the clarity and completeness of the displayed content (floor number, running direction, fault prompts, etc.). Operate the elevator in inspection mode to confirm that the display can accurately and synchronously update the elevator’s real-time status. For touch-enabled models, test the touch response sensitivity and accuracy to ensure smooth operation of functions such as floor selection (if integrated) or mode switching. If there is abnormal display (dim light, missing content, flickering) or unresponsive touch, recheck the wiring and installation status and adjust in time.

2. Daily Operation & Routine Inspection

• During daily elevator operation, observe the display status regularly. Abnormal phenomena such as no display, blurred content, flickering, delayed information update, or unresponsive touch (for touch-enabled models) indicate possible display failures or wiring problems.
• Conduct weekly visual inspections and cleaning: Use a dry, lint-free microfiber cloth to gently wipe the surface of the display screen to remove dust, fingerprints, and minor stains. Avoid using water, alcohol, acetone, or other corrosive/volatile cleaners that may damage the screen’s anti-glare coating or touch-sensitive layer. Check the display’s edge and fixing screws for cracks, deformation, or looseness, and retighten loose screws in a timely manner to prevent the display from falling off due to elevator vibration.
• Regularly check the wiring connections at the back of the display (after cutting off the power supply). Ensure the wires are not loose, aged, or damaged, and the terminals are free of oxidation. If any wiring issues are found (such as loose terminals, broken wires, or oxidized contacts), resolve them immediately to avoid display malfunctions.

3. Regular Maintenance

• Every 3 months, thoroughly inspect the display’s installation status and wiring connections. Check if the display is loose or displaced due to long-term elevator vibration and adjust the fixing screws if necessary. Use a multimeter to detect the power supply voltage of the display to ensure it is within the standard range (typically DC 12V ± 0.5V or 24V ± 1V), avoiding damage to internal components caused by voltage fluctuations.
• Every 6 months, conduct a comprehensive performance test: Verify the display’s brightness, contrast, and color uniformity. Calibrate the brightness to ensure clear visibility under both strong light (e.g., sunlight entering the cab) and low light conditions. For touch-enabled models, test the touch response speed and accuracy across the entire screen area to ensure no dead zones. Check the integrity of the display interface and confirm that all status information and prompt messages can be displayed normally.
• Annually, conduct a professional maintenance: Contact Nanjing Zhuye Elevatorparts’ technical personnel to disassemble and inspect the internal components of the display, including the LCD module, circuit board, touch panel (if applicable), and connectors. Clean the internal dust (if any) with a professional dust blower, and replace aging components (such as capacitors or connectors) if necessary to ensure the long-term stable operation of the display.

Recommended Replacement Cycle of Monarch Elevator Car 7-Inch LCD Display SFTC-CCB-T7(TS7)-TPJ-YY

1. Standard Replacement Cycle

2. Scenario-Based Cycle Adjustment

• Harsh Operating Environments: For elevators operating in high-humidity coastal regions, high-dust construction sites, high-temperature unventilated cabs, or areas with strong electromagnetic interference (e.g., near industrial equipment), the replacement cycle should be shortened to 4–5 years. Harsh conditions accelerate the aging of LCD modules, corrosion of circuit boards, damage to the touch panel (if applicable), and degradation of display performance, reducing the display’s reliability and service life.
• Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with less than 3,000 monthly rides) and stable cab environmental conditions, the replacement cycle can be appropriately extended to 7–8 years after a professional inspection by Nanjing Zhuye Elevatorparts confirms that the display’s brightness, display clarity, touch response (if applicable), and structural integrity are intact.

3. Immediate Replacement Conditions

• The display screen is severely cracked, scratched, or the backlight is permanently damaged, resulting in unclear display, missing content, or unreadable information that cannot be improved by cleaning or adjustment.
• The display has persistent faults such as no display, frequent flickering, black screen, or garbled characters, and the fault cannot be eliminated after checking wiring, power supply, and circuit connections.
• For touch-enabled models, the touch panel has obvious dead zones, delayed response, or unresponsive operation, and the fault cannot be resolved by calibration or maintenance.
• The display fails the annual performance test, and key indicators (brightness, contrast, signal stability, touch accuracy) cannot be restored to the standard range even after maintenance.
