Tab.2/4: Status LED short circuit/overload
Reaction to short circuit in the sensor supply
If there is a short circuit, the input module will switch off the
power supply to the sensors and communicate the fault to
the CP master. The status LEDs will be switched off and the
inputs of the module supply a 0−signal. The power supply will
be switched on again automatically when the short circuit has
been eliminated.
