Otis Elevator LOP HAA23500K1 – Installation, Programming & Replacement Guide
Nanjing Zhuye Elevator Parts – OEM stock, global shipping, 24/7 support
Nanjing Zhuye Elevator Parts – OEM stock, global shipping, 24/7 support
The HAA23500K1 is the ultra-slim Landing Operating Panel board that drives every stainless-steel LOP in Otis Gen2® and SkyRise® installations delivered since 2017. Only 18 mm deep, this PCB handles 24 illuminated buttons, a 3-digit 7-segment direction display, full-duplex intercom and streams data to the iController via a single CAN-bus pair. A cracked display driver or oxidised CAN transceiver will throw a “314” fault and blank every landing button overnight. Nanjing Zhuye Elevator Parts keeps thousands of factory-flashed HAA23500K1 boards in Rotterdam and Nanjing so you can restore full landing service the same day. Below is an 800-word field manual that explains correct usage, on-site programming and the replacement cycle that keeps your elevators answering every call.
1. What the HAA23500K1 does
-
24 illuminated push-button inputs with diode-matrix ghosting protection
-
3-digit 7-segment LED display (direction + floor) 150 cd/m² @ 24 Vdc
-
CAN 2.0B interface, 125 kbit/s, SIL-2 safe communication
-
On-board 5 Vdc buck, 3 A, short-circuit and thermal protected
-
IP42 ABS housing with key-hole slots for 30-second swap
-
UL/CE recognised to EN 81-20/50 and CSA B44.1 for 10-year design life
2. Tools to carry
-
HAA23500K1 LOP board (Nanjing Zhuye part #OT-LOP-HAA23500K1-LED) in anti-static bag
-
2 mm & 3 mm flat screwdrivers, TX10 Torx
-
Otis Service Tool (OST) laptop with LOP plug-in licence
-
RJ-45 to M12 adapter cable (2 m, shielded)
-
IPA wipes and lint-free cloth
-
Feeler gauges 0.05–0.2 mm
-
Lock-out / tag-out kit
3. Installation – 10 minutes if you label the wires
Safety: place the car on inspection, open the main disconnect and verify 0 V on the 24 Vdc rail.
-
Photograph every J-connector – note J1 (24 V), J2 (CAN), J3 (buttons), J4 (display), J5 (audio).
-
Depress the bezel latches and hinge the LOP mask forward; store screws in magnetic tray.
-
Slide the old board upward; it unhooks from the plastic dovetail.
-
Clean the bezel and gasket with IPA; remove any glue residue.
-
Fit the new HAA23500K1: hook top edge first, press until latch clicks.
-
Re-connect all plugs; tug-test each one.
-
Apply power – STATUS LED blinks green 3 times then solid; display shows current floor.
-
Press each button; confirm call registers and halo extinguishes after door close.
-
Record serial number, date and button map in CMMS.
4. Functional test – prove it to the inspector
a) Button actuation force: 1.5 N ±0.3 N at plunger centre.
b) Display brightness: 150 cd/m² measured with lux meter.
c) CAN-bus latency: <2 ms between press and controller receipt.
d) Phase-II recall: pressing fire-service key blanks landing calls and lights red LED.
e) Export OST report and attach PDF to site file.
b) Display brightness: 150 cd/m² measured with lux meter.
c) CAN-bus latency: <2 ms between press and controller receipt.
d) Phase-II recall: pressing fire-service key blanks landing calls and lights red LED.
e) Export OST report and attach PDF to site file.
5. Preventive maintenance schedule
-
Monthly – visual sweep for cracked lenses or dark segments.
-
Quarterly – measure 24 Vdc ripple (<100 mV) and CAN-bus termination (60 Ω).
-
Annually – clean button mat with IPA; inspect for carbon tracks from arcing.
-
Every two years – replace the anti-scratch lens film – keeps display crystal-clear.
6. Replacement cycle – traffic and vandalism decide
Otis specification: 10 years. Nanjing Zhuye analytics refine this to real-world duty:
-
Light duty (<150 starts/day, clean office): 12 years
-
Standard duty (150–400 starts, residential): 10 years
-
Heavy duty (>400 starts, hospital, mall): 8 years
-
High vandalism (school, station): 5 years – lens and buttons crack under impact.
Replace immediately if:
-
Display digits missing or segments flickering – driver IC blown
-
CAN-bus error frame count >1 % – transceiver cracked by vibration
-
Button halo <50 % brightness – LED chain degradation
-
Housing cracks exposing live parts – safety violation
