Reboot Loop OSPi

[Anonymous]

Hello,

After the winter I would like to get my OSPi back into operation. Unfortunately the board starts in a continuous loop.

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

After about 10 seconds:

– The LED on the board continues to light up
– The LEDs on the Pi switch off briefly, then red permanently, yellow intermittently
– The humming of the power supply becomes quieter briefly

This happens in a continuous loop

I tried the following:
– new installation PI and OpenSprinkler on new SD card
– Pi started without a board: no problems
– Voltage measurement at the power supply output when switching on: constant voltage, no fluctuations
– Board switched on without PI: LED lights up permanently, and there is no humming from the NT
– Plug to the valves removed: no difference

HW:
– OSPi v1.43+
– RasPi 3.b v2

Does anyone have an idea how I can get the OSPi back up and running?

Hello,

good question, the Raspberry PI actually only reboots when there is not enough power being supplied.

What kind of power supply is connected?

If you unplug both green plugs, nothing changes?

Hello,
It is operated via a top-hat rail power supply from comatec. Output 24V and 74VA.

The problem persists even after removing the plugs.

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

Sensor connected?
