Otis Detection Board XDH422P003 V1.0 – Precision Sensing for Safer, Smarter Elevator Operation | Nanjing Zhuye Elevator Parts
Every Otis elevator is a moving sensor network. The XDH422P003 V1.0 detection board is the “eyes and ears” that see doors closing, feel car vibration, hear rope slip and smell rising oil temperature. Built for the XRDS and Gen2® families, it filters, amplifies and digitises these signals, then streams them to the CPU over CAN-FD. When it blinks, the car becomes blind—doors rebound, levelling drifts, or the whole group stops. Nanjing Zhuye Elevator Parts keeps genuine XDH422P003 V1.0 boards in anti-static packaging, pre-flashed with the latest firmware and ready for same-day despatch—helping you restore full vision without costly OEM delays.

-
Door zone detection, light-barrier, comb impact, handrail speed, motor vibration
-
Modernisation packages adding predictive-maintenance sensors to older cars
-
Any controller needing SIL-2 certified analogue and digital inputs
Installation method – 10-minute plug-and-see
-
Place lift on inspection mode; switch OFF main breaker; lock & tag.
-
Wait 3 min for DC bus to discharge; verify zero energy.
-
Photograph existing wiring; note CAN-FD and sensor plug orientation.
-
Release DIN-rail clip; slide old XDH422P003 upwards and out.
-
Clip new board onto TS-35 rail until latch clicks.
-
Re-connect 24 V DC, CAN-FD, analogue sensors, digital inputs, shield drain to PE.
-
Power up; blue “RUN” LED flashes during boot, then solid green = ready.
-
Launch Otis Sensor Tool (OST-3.11) on laptop; auto-detects board in 5 s.
-
Calibrate zero: vibration < 0.1 g, door zone 2.5 V, light-barrier 24 V present.
-
Log serial number and firmware v3.11 in maintenance book.
Replacement cycle & preventive maintenance
Although fan-less, ADC references and opto-couplers age. Otis bulletin SB-XDH-2024-03 recommends:
-
Visual inspection every 6 months: clean USB-C port, check for loose terminals.
-
Sensor calibration every 12 months: verify ±1 % accuracy against certified source.
-
Replace entire board every 10 years or 87 600 operating hours (24 h × 365 × 10).
-
Immediate replacement if:
– “RUN” LED off while 24 V present,
– analogue drift > ±3 % after calibration,
– CAN-FD error frames > 1 % (optocoupler fatigue),
– temperature > 70 °C on IR camera (vent blocked).
Pro tip: 70 % of premature failures are traced to loose sensor terminals—re-torque to 0.5 Nm every year.
Maintenance tips from Nanjing Zhuye Elevator Parts
-
Always use shielded sensor cables, foil facing inward, grounded at board only, to prevent noise.
-
Never leave USB-C cap open; dust kills the port within 6 months.
-
Keep a spare XDH422P003 in every service van; at 0.14 kg it costs less than one extra site visit.
-
After lightning storm, check 24 V ripple < 1 V; high ripple corrupts ADC readings.
-
Order the “Detection Bundle” (board + DIN-rail clip + terminating resistor) 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 XDH422P003 V1.0 directly from the Czech factory, ageing every unit for 2 h at 60 °C and shipping with a 24-month replacement warranty. Stock is stored in humidity-controlled bins to prevent ADC 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 pre-calibrate sensor offsets and include a loaner unit to keep your detection alive during the swap.
Conclusion
The XDH422P003 V1.0 detection board is the silent stethoscope that keeps every Otis lift healthy. By installing the genuine unit, calibrating sensors regularly and replacing it before ADC drifts, you turn guess-work into data, reactive calls into predictive maintenance and passenger complaints into compliments. Stock genuine XDH422P003 V1.0 from Nanjing Zhuye Elevator Parts today—because when detection stops, insight stops.
