Significance
External fault Short circuit of the transmitter power supply
External fault Signal line to transmitter interrupted or short
circuited
Short circuit Signal output short circuited
Overvoltage Field voltage to the signal output inadequate
Line break fault Signal line to the actuator interrupted or not
connected
External fault Short circuit of the signal output against
+24V or GND, signal line to the actuator is
interrupted or not connected or excess
temperature through overloading.
External fault External fault (broken wire, overload or short
circuit, manual operation)
Broken wire Signal line to transmitter interrupted
Lower limit value Measurement range shortfall or signal line to
undershot the transmitter has a short circuit
Fault Internal fault (e.g. hardware)
Upper limit value Measurement range overflow
exceeded Internal fault (e.g. hardware fault)
Fault
Upper limit value Measurement range overflow of the input
exceeded signal
Lower limit value Measurement range shortfall of the input
undershot signal
Fault Internal fault (e.g. hardware fault)
Overvoltage
Upper limit value Measurement range overflow of the input
exceeded signal
Fault Internal fault (e.g. hardware fault)
