General troubleshooting
For local display
Problem
Possible cause
Remedy
Local display dark and no output signals Supply voltage does not match that
specified on the nameplate.
Apply the correct supply voltage
(
Local display dark and no output signals Supply voltage has incorrect polarity.
Reverse polarity of supply voltage.
Local display dark and no output signals No contact between connecting cables
and terminals.
Check the contacting of the cables and
correct if necessary.
Local display dark and no output signals Terminals are not plugged into the I/O
electronics module correctly.
Check terminals.
Local display dark and no output signals I/O electronics module is defective.
Local display is dark, but signal output
is within the valid range
Display is set too bright or too dark.
• Set the display brighter by
simultaneously pressing
O
+
F
.
• Set the display darker by
simultaneously pressing
S
+
F
.
Local display is dark, but signal output

parameter.
For output signals
Problem
Possible cause
Remedy
Signal output outside the valid range
Main electronics module is defective.
Signal output outside the valid current
range
(
<
3.6 mA or
>
22 mA)
I/O electronics module is defective.
Device shows correct value on local
display, but signal output is incorrect,
though in the valid range.
Configuration error
Check and correct parameter
configuration.
Device measures incorrectly.
Configuration error or device is
operated outside the application.
1. Check and correct parameter
configuration.
2. Observe limit values specified in the
"Technical Data".
For access
