Note
Measurement type resistor (3-wire terminal)
A wire break of the M+ cable is not detected with measurement type resistor (3-wire
terminal). An incorrect measuring value is output in this case.
36
Diagnostics alarms - for the measuring range: 0 V to 10 V and 4-DMU 0 mA to 20 mA
Error code Meaning
1 Short-circuit encoder supply to
H
ground
7 Value is above overrange.
H
8 Value is below underrange.
H
9 Value is significantly above or
H
below underrange/overrange.
10 Module parameter assignment is
H
faulty
16 At least one hardware interrupt
H
could not be signaled because
too many hardware interrupts are
pending.
Diagnostics alarms - for the measuring range: 150 Ω and 300 Ω
Error code Meaning
6 Impedance of encoder circuit too
H
high
Wire break between the module
and sensor
Channel not connected (open)
7 Value is above overrange.
H
10 Module parameter assignment is
H
faulty
16 At least one hardware interrupt
H
could not be signaled because
too many hardware interrupts are
pending.
Remedy
Correct interplay between mod-
ule and encoder
Correct interplay between mod-
ule and sensor
Correct interplay between mod-
ule and sensor
Correct interplay between mod-
ule and sensor
Correct the parameter assign-
ment
Correct the program or the pro-
cess
Remedy
Use a different encoder type or
modify the wiring, for example,
using cables with larger cross-
section
