Elevator Emergency Lighting Power Supply RKP220 (6V/12V/24V): Emergency Power Core from Nanjing Zhuye Elevatorparts

Step-by-Step Usage Guide for Elevator Emergency Lighting Power Supply RKP220 (6V/12V/24V)

1. Professional Installation & Wiring

• Safety Preparation: Cut off the elevator’s main power supply and the emergency lighting system’s dedicated power supply. Clean the mounting area (usually in the elevator car ceiling, control cabinet, or shaft) to remove dust, oil stains, and debris that may affect insulation and heat dissipation. Check the input power parameters to ensure they match the RKP220’s rated input requirements.
• Power Supply Installation: Fix the RKP220 power supply to the dedicated mounting bracket using high-strength screws provided by Nanjing Zhuye Elevatorparts. Ensure the power supply is installed vertically (tilt angle ≤ 5°) and there is a 10–15mm heat dissipation gap between adjacent components. Confirm that the power supply’s ventilation holes are not blocked and that the battery compartment is sealed tightly to prevent moisture intrusion.
• Wiring Operation: According to the emergency lighting system wiring diagram, connect the AC input wire to the RKP220’s input terminal, the DC output wire to the emergency lighting fixtures (ensure the voltage specification matches), and the signal wire to the elevator main control system (for fault monitoring). Ensure the wiring is tight (use a torque wrench to confirm the tightening torque) and the positive/negative poles are correctly connected (reverse connection will damage the power supply or lighting fixtures). For lithium battery versions, avoid short-circuiting the battery terminals during wiring.
• Post-Installation Testing: Restore the power supply and conduct comprehensive functional tests. Check if the power supply’s indicator lights (charging, normal operation, emergency mode) work normally. Simulate a main power failure to verify that the RKP220 switches to emergency power supply within 0.5s and the emergency lights illuminate stably. Test the backup duration by maintaining the emergency mode until the battery is exhausted (should meet ≥ 90 minutes). If there is unstable output voltage, slow emergency switching, or insufficient backup duration, recheck the installation and wiring immediately.

2. Daily Operation & Routine Inspection

• Daily Visual Inspection: During elevator patrols, check the external state of the RKP220 power supply. Ensure the ABS shell is free of cracks, deformation, or corrosion; the wiring terminals are tight with no looseness, oxidation, or burning marks; the indicator lights show normal charging status (usually green).
• Weekly Functional Check: Simulate a main power failure once a week to verify the emergency switching performance of the RKP220 and the normal illumination of emergency lights. Use a multimeter to detect the output voltage (ensure it matches the rated voltage: 6V/12V/24V ± 5%). Check the battery voltage (when disconnected from the main power) to ensure it is within the normal range.
• Monthly Parameter Monitoring: Turn off the power supply and clean the power supply’s shell and ventilation holes with a dry, lint-free cloth to remove dust and debris. Inspect the built-in battery for bulging, leakage, or abnormal odor (replace the battery if any). Check the tightness of the mounting screws and wiring terminals to prevent loosening due to elevator vibration.

3. Regular Maintenance Schedule

• Quarterly Maintenance: Disconnect the power supply and remove the RKP220 from the mounting bracket. Thoroughly clean the shell, terminals, and battery compartment with a professional electrical cleaner. Inspect the input/output wires for aging or cracking (replace if necessary) and recheck the tightness of all connections. Reinstall the power supply and perform a full charge-discharge cycle to activate the battery and verify its capacity.
• Semi-Annual Performance Test: Conduct a comprehensive performance test, including output voltage stability, emergency switching time, and backup duration. Use a professional power supply tester to simulate different working conditions (e.g., low-temperature environment, voltage fluctuation) to verify the power supply’s stable operation. For elevators in high-traffic areas (e.g., shopping malls, airports) or harsh environments (high humidity), increase the test frequency to once every 3 months.
• Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Replace the built-in battery (recommended replacement cycle for lead-acid batteries is 2–3 years, for lithium batteries is 3–4 years) and aging components (such as capacitors, resistors) with genuine parts. Recalibrate the charging voltage and protection function parameters to meet the original factory standards and the elevator’s actual operating requirements.

Recommended Replacement Cycle for Elevator Emergency Lighting Power Supply RKP220 (6V/12V/24V)

1. Standard Replacement Cycle

2. Adjustments for Special Scenarios

• Harsh Environments: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or elevators with frequent main power failures (annual switching times > 200), the replacement cycle should be shortened to 2–3 years (lead-acid battery version) and 3–4 years (lithium battery version). Harsh conditions accelerate battery aging, corrosion of terminals, and degradation of internal circuit performance.
• Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable environments, the replacement cycle can be extended to 4–5 years (lead-acid battery version) and 5–6 years (lithium battery version)—only if Nanjing Zhuye’s professional inspection confirms that the power supply’s emergency switching performance, backup duration, and battery capacity are all intact.

3. Immediate Replacement Conditions

• The emergency switching time exceeds 1s, or the power supply fails to switch to emergency mode during main power failures, leading to blackout in the elevator car.
• The backup duration is less than 30 minutes (after full charge), which cannot meet the minimum safety evacuation time requirement.
• The built-in battery has obvious bulging, leakage, or abnormal odor; the battery capacity drops by more than 50% compared to the new battery, and cannot be restored through maintenance.
• The power supply has no output (confirmed by multimeter testing), or frequent fault alarms occur, and the fault cannot be eliminated by checking the input power and wiring, affecting the normal operation of the emergency lighting system.
