11 Diagnostics
The LEDs on the head module and expansion modules indicate the status of the modules
and report on operating states as well as external and internal errors. The Module LED in-
dicates the status of the module; the function LEDs (In, Out, Start) indicate the status of the
inputs and outputs.

11.1 Status messages
These messages provide information about the status of the myPNOZ and the inputs/out-
puts.
Status messages during initialisation
After the myPNOZ is started there is a brief initialisation phase.

Initialisation
Status messages during operation (RUN)
During operation, where there are no errors present, the states of the inputs and outputs
are displayed. The Module LED light up green. If the colour of the Module LED turns or-
ange, this is a warning about one of the following errors:
} Supply voltage increased or low
} Supply voltage to semiconductor outputs increased or low
} Temperature increased or low
} Connection between modules disturbed by external influences
myPNOZ only switches to an error state when the error means that a limit value is ex-
ceeded. If the error is no longer present, the Module LED switches back to green.
