Status indicator in STOP state
If myPNOZ is in a STOP state, the states of the inputs and outputs are displayed. All the
module LEDs in one zone flash identically. The module LEDs in the following zone flash in-
versely.
If an error occurs, the module LED switches its colour from green to orange. Errors may be:
} Supply voltage increased or low
} Supply voltage to semiconductor outputs increased or low
} Temperature increased or low
If the error is no longer present, the LED switches back to green. If the error means that a
limit value is exceeded, myPNOZ switches to an error state.
