Otis Elevator LOP DAA23500CD7 – 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 DAA23500CD7 is the ultra-slim Landing Operating Panel board that controls every stainless-steel LOP in Otis Gen2® and SkyRise® installations delivered since 2019. Only 16 mm deep, the PCB drives 24 illuminated square buttons, a 3-digit 7-segment directional 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-tested DAA23500CD7 boards in Rotterdam and Nanjing so you can restore perfect indication 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 bright, safe and code-compliant.

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 DAA23500CD7: 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:
-
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
