7.5
Error in the system/sensor power supply
The voltage value for the system/sensor power supply is also monitored
globally. If the value is beyond the voltage range of 18.6 to 30 V, an error
message is created.
The U
S
indicator lights up red and the sensor under voltage bit is set in the
module information byte.
The error message has no effect on the outputs and is not filtered, but is
reported immediately.
CAUTION
It must definitely be ensured that the supply voltage, measured at the most
remote participant is not below 18,6 V DC from the perspective of the
system power supply.
