Cause of error
• Error in the field circuit
• Wire breakage or short
• circuit
• Measuring range has been
overshot or undershot
Configuration is not correct or the
wrong module is connected
Cyclic data transfer with the
automation system has been
interrupted
"Plant STOP" at terminal X0
activated ("24 V" LED lights up
yellow)
Module is defective
Ambient temperature is
outside the specification
• Module is damaged due to
excessive temperature or
end of service life reached
• Fault in redundant BusRail
connection
• Slot address changed
without authorisation
outside the voltage range
<18 V or >32 V
"Plant STOP" activated
Line breakage or short circuit
Troubleshooting
• Check the "red" signal LEDs
• Eliminate the cause in the indicated
field circuit, check electrical lines and
field devices
Change configuration in the automation
system or connect the correct module
• Check the cyclic data transfer of
CPM or CPU (LCD or "RUN" LED)
• Check bus connection
• Activate the cyclic data transfer with
the automation system
• Check whether the terminal and
jumper were installed (correctly)
• Where necessary,
deactivate terminal X0
Replace the module
Reduce ambient temperature,
e.g. by shading or cooling
Note: Module will be permanently damaged
if not rectified
• Replace the module as soon as
possible (within the next 12 months),
otherwise there is a risk of module
failure
• Check the BusRail connection and
CPU & PM
• Replace the module
Check external supply voltage at terminal X0
• Check whether the X0.3-X0.4 terminal
and jumper were installed (correctly)
• If necessary, deactivate "Plant STOP"
(X0 input)
Eliminate the cause in the indicated field
circuit, check electrical lines and field device
Note: "Short circuit" and "Line breakage
with test current deactivated" can only be
detected when the output is activated.
