12 Diagnostics and troubleshooting
12.1 General troubleshooting
Problem Possible cause Remedy
Local display dark and no signal
output at current output (0 mA) Supply voltage does not match that
specified on the nameplate. Apply the correct supply voltage
(
®
ä 26).
Supply voltage has incorrect polarity. Reverse polarity of supply voltage.
No contact between connecting cables
and terminals. Check the contacting of the cables and
correct if necessary.
Terminals are not plugged into the I/O
electronics module correctly. Check terminals.
I/O electronics module is defective.
Order spare part (
®
ä 91).
Local display is dark, but signal
output is within the valid current
range (3.6 to 22 mA) 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
.
Spiral cable of the display module is not
plugged in correctly. Insert the plug correctly into the main
electronics module and display module.
Display module is defective. Order spare part ( ®
ä
91).
Signal output outside the valid
current range
(
<
3.6 mA or
>
22 mA)
Main electronics module is defective. Order spare part (
®
ä
91).
I/O electronics module is defective. Order spare part (
®
ä
91).
Device shows correct value on local
display, but signal output is
incorrect, though in the valid
current 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".
Text on measured value display and
in navigation view appears in a
foreign language and cannot be
understood Incorrect operating language is
configured. 1. Press 2 s
S
+
O
("home position").
2. Press
F
.
3. Set the desired language in the
Language parameter.
No connection via HART protocol Missing or incorrectly installed
communication resistor. Install the communication resistor (250
W ) correctly. Observe the maximum load
(
®
ä
