1.6.4 Undervoltage (US)
If the power supply of the digital outputs underpasses 17 V, a power fail message is sent
to the controller and the LED ‘US’ extinguishes. The outputs are switched off.
1.6.5 Cross-Polarity
The power supply UC is protected against cross-polarity, which is not the case for the
power supply US.
1.6.6 Short Circuit
A short circuit at a digital output produces a switch off of all digital outputs of the module
concerned and the red LED "S" lights on.
If an analog output is overcharged, the technical data cannot anymore be guaranteed. The
outputs are however not damaged if the current does not exceed 30 mA (not short circuit
proofed), no feedback message is generated.
