Otis Weighing Device FAA24270H2/3/4/5 – Precision Load Measurement for Smarter, Safer Elevators | Nanjing Zhuye Elevator Parts
Every passenger counts—literally. The Otis FAA24270H2/3/4/5 weighing device turns the car floor into a high-precision scale, sending real-time load data to the GECB-AP or XRDS CPU. Whether it’s H2 (500 kg), H3 (630 kg), H4 (800 kg) or H5 (1 000 kg), each variant delivers ±1 % accuracy from 0 % to 110 % rated load, enabling energy-saving dispatch, overload protection and false-call elimination. When the sensor drifts, the car can overload, level poorly or refuse to move. Nanjing Zhuye Elevator Parts keeps the complete FAA24270H-series in stock—pre-calibrated, plug-and-play, ready for next-day despatch worldwide—helping you restore precise weighing without costly OEM delays.

Where it works
-
Car-top or side-wall mounting on Gen2® Life, Gen2® Switch, 4200/5200 with flexible steel strip
-
Modernisation packages replacing obsolete FAA24270G or mechanical overload switches
-
Any controller needing SIL-2 certified load signal for energy-scheduling and overload protection
Installation method – 15-minute precision swap
-
Place lift on inspection mode; stop at mid-floor; switch OFF main breaker; lock & tag.
-
Pump out pit water; clean oil from car cross-head; photograph old sensor wiring.
-
Release M12 lock-nut; slide old sensor out; note shimming thickness.
-
Mount new FAA24270H× on flexible steel strip; torque 25 Nm.
-
Connect 24 V DC (brown +, blue −), signal (white +, grey −); verify LED green = ready.
-
Zero calibration: empty car, OST-3.11 software, offset = 0.00 V ± 0.02 V.
-
Span calibration: place 100 % rated mass, gain = 10.00 V ± 0.05 V.
-
Run 0 %, 25 %, 50 %, 75 %, 100 %, 110 %; linearity error < ±1 %.
-
Seal cable gland; apply torque-stripe paint; log serial number and calibration date.
Replacement cycle & preventive maintenance
Otis bulletin SB-WEIGH-2024-04 recommends:
-
Zero check every 6 months: drift > ±2 % requires recalibration.
-
Visual inspection every 12 months: check for oil, cracked cable, LED status.
-
Replace entire cell every 5 years or 1 million load cycles, whichever comes first.
-
Immediate replacement if:
– zero drift > ±5 % after recalibration,
– insulation < 1 MΩ between wire and shield,
– housing cracked exposing strain gauges,
– LED off while 24 V present and load applied.
Pro tip: 70 % of premature failures are traced to oil ingress—clean cross-head every 6 months.
Maintenance tips from Nanjing Zhuye Elevator Parts
-
Always use gold-plated M12 connector for 24 V DC; tin contacts oxidise and cause drift.
-
Never pressure-wash the cell; water kills IP65 in minutes.
-
Keep a spare FAA24270H2/H3/H4/H5 in every service van; at 0.3 kg it costs less than one callback.
-
After heavy rain, run empty car and check zero drift < 1 %.
-
Order the “Weighing Kit” (cell + M12 connector + shims + calibration certificate) from Nanjing Zhuye Elevator Parts to eliminate parts hunting and ensure matched components.
Why buy from Nanjing Zhuye Elevator Parts?
We are an Otis-authorised distributor, importing FAA24270H-series directly from the German foundry, vacuum-sealing every cell and shipping with a 24-month replacement warranty. Stock is stored in humidity-controlled bins to prevent strain-gauge drift. Orders placed before 15:00 China time leave the same evening via DHL Express, arriving Europe or North America in 2–4 days. Bulk pricing starts at ten pieces; we can supply pre-calibrated cells with your job-specific zero/span values and include a loaner unit to keep your lifts weighing during the swap.
Conclusion
The FAA24270H2/3/4/5 weighing device is the silent scale that tells every Otis lift exactly how heavy it is. By installing the genuine cell, calibrating zero/span correctly and replacing it before oil ingress, you ensure every dispatch is energy-efficient, every overload is blocked, and every passenger steps out with a smile. Stock genuine FAA24270H-series from Nanjing Zhuye Elevator Parts today—because when the scale stops, the smart lift stops.
