The idea is to shutdown a failed compressor before it scatters metal throughout the system. Several things besides an internally failed compressor can cause the sensor to trip; a slipping belt, a slipping clutch or a worn compressor that allows the compressor innards to have excessive thrust.

Hope this helps.
As a follow-on to this, I would recommend eliminating the Klima circuit that monitors these various parameters as a test.

Pull the Klima and connect a jumper between sockets 5 and 7. The compressor will start. See if it continues to run past the 10 minute point. If it does, the problem is in the Klima..........one of it's parameters is not to spec.

If it doesn't........I'd be inclined to believe the evap temp switch is NG.

The real question is whether the compressor ever comes back online after it shuts down.........if it never comes back until a restart, the problem is most certainly with the Klima.
