reboot loop OSPi

[Anonym]

Hallo,

after the winter I would like to think OSPi put back into operation. Unfortunately, the board starts in a continuous loop.

As soon as the voltage is applied, the following happens:
– The LED of the OSPi goes to
– The red status LED on the Pi lights up
– The yellow LED on the Pi lights up/flashes
– After a short time, the LEDs of the network adapter light up.
– The power pack emits a quiet hum

After about 10 seconds:

– The LED on the board remains lit
– The LEDs on the Pi switch off briefly, then red continuously, yellow with an interruption
– The hum of the power supply unit becomes quieter for a moment

This happens in a continuous loop

I tried the following:
– new installation PI and Opensprinkler on a new SD card
– Pi started without board: no problems
– Measure the voltage at the power pack output when switching on: constant voltage, no fluctuations
– Board switched on without PI: LED lights up continuously, also no humming of the NT
– Plugs to the valves removed: no difference

HW:
- OSPi v1.43+
– Raspberry Pi 3.b v2

Does anyone have an idea how I can do that OSPi can be put back into operation?

Hallo,

good question, the Raspberry PI actually only reboots if not enough power is supplied.

What kind of power supply is connected?

If you unplug both green plugs, nothing changes?

Hallo,
it is operated via a comatec DIN rail power supply. Output 24V and 74VA.

The problem persists even after unplugging the connector.

Hello, could you possibly be a little more specific with the power supply unit? Designation? It's usually all there. Or photo of the installation?

sensor connected?
