5124340 is the PPQ weighing board of the Orona ARCA II generation, the Orona elevator PCB board that turns the car load sensors into a weight value for the controller. Orona’s parts list places it in the car sling or on the car roof, and calls it the weighing card. The controller uses it for load compensation and full-load handling, so a failure shows as wrong load behaviour, not a stopped lift. Order by the number on the board.

ARCA 2 cabinet boards:
Potensi supplies the Orona elevator load weighing board PPQ 5124340, the Orona elevator PCB board for the car and the ARCA 2 cabinet boards around it. The models above are only a part of what we can supply. We stock and source a much wider range of related and alternative models. If your model number is not listed here, please send us the model number or a photo of the original part, and we will confirm availability and the correct match for you.
Q1: What does the PPQ board do?
A: It is the weighing card of the installation: it takes the signals from the car load sensors and turns them into a load value for the controller. The controller then uses that value for load compensation and for full-load handling, so the lift starts and levels the same way whether the car is empty or full. It is a measuring board, which is why a fault shows as wrong load behaviour and not as a lift that refuses to run.
Q2: Where is it mounted?
A: Orona’s parts list places the PPQ in the car sling or on the car roof, and it is also used in modernization work. Some suppliers file it under cabinet boards, but the board itself belongs to the car side and is wired to the load sensors there. Look for it above the car, not in the machine room cabinet.
Q3: Which Orona lifts take this board?
A: 5124340 belongs to the ARCA II generation and is listed by Orona’s distributors with the ARCA 2 tag. The later ARCA 3 range uses different numbers, so a board from that family will not do the same job. If your controller is an ARCA 3, send us the number on the old board before ordering.
Q4: Does the weighing need setting up after replacement?
A: Plan on it. The weighing is set up against the installation, so a new board has to be brought into line with the car it serves. Check the sensor wiring and the sensor mounting first, because a loose sensor will look like a board fault. Then run the weighing set-up for that site, with a known load, before the lift goes back into service.
Q5: The lift reports full load with a light car, or starts badly when loaded. What should I check?
A: Start at the sensors: a damaged sensor, a broken wire or a sensor that has moved gives exactly that picture. Then check the PPQ connectors and the supply reaching the board. If the sensors and the wiring are sound, the board is the next suspect, and a photo of it with the fault present helps us confirm the version.
Q6: What should I send before ordering?
A: A photo of the old board, front and back, with the number and every connector visible. Tell us the controller generation and, if you have it, the number of load sensors in the car. With that we confirm the board and the wiring variant before dispatch.
