Parameterization
error Parameterization at run
time:
Wrong function code in
record set Proof the parameteri-
zation during run time
Wire break Sensor allocation is too
high-impedance install another sensor
type or cable with a
higher cross-section
Interruption of the conductor
between module and sensor Install conductor
connection
Channel is not wired (open) Deactivate the channel
group (parameter
measuring type)
Wire the channel
Measuring range
underflow Input value is under the
underdrive region, error
causes may be:
•
at measuring range
4 ... 20mA, 1 ... 5V
- sensor connection
polarity inversion
- wrong measuring range
•
other measuring ranges
- wrong measuring range
Check connections
Parameterize another
measuring range
Parameterize another
measuring range
Measuring range
overflow Input value higher than
overdrive region Parameterize another
measuring range
Process interrupt
lost During the processing of a
process interrupt in OB40, a
new process interrupt with
the same error cause
occurs.
Failure of the
external power
supply Connection of the external
power supply forgotten
Power supply failure
Cable defect res. not
correctly connected Supply the module with
external DC 24V
Control external power
supply and change it
Control cable res.
replace it
Common mode Different potentials between
grounds >3V or wire break
at ground Remove wire break,
lower potential
