Error
Possible causes
Solution
Device shows correct value on local
display, but signal output is
incorrect, though in the valid range.
Configuration error
Check and correct the 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
Error
Possible causes
Solution
No write access to parameters
Hardware write protection enabled
Set the write protection switch on
main electronics module to the
OFF
position → 124.
No write access to parameters
Current user role has limited access
authorization
1. Check user role → 57.
2. Enter correct customer-specific
access code → 57.
No connection via HART protocol
Communication resistor missing or
incorrectly installed.
Communication resistor (250 Ω)
correctly. Observe the maximum
load → 169.
No connection via HART protocol
Commubox
• Connected incorrectly
• Configured incorrectly
• Drivers not installed correctly
• USB interface on computer
configured incorrectly
Observe the documentation for the
Commubox.

"Technical Information"
TI00404F
Not connecting to Web server
Web server disabled
Using the "FieldCare" or "DeviceCare"
operating tool, check whether the
web server of the measuring device
is enabled, and enable it if
necessary→ 64.
Incorrect setting for the Ethernet
interface of the computer
1. Check the properties of the
Internet protocol (TCP/IP)
→ 60→ 60.
2. Check the network settings with
the IT manager.
Not connecting to Web server
Incorrect IP address
Check the IP address:
192.168.1.212 → 60→ 60
Not connecting to Web server
Incorrect WLAN access data
• Check WLAN network status.
• Log on to the device again using
WLAN access data.
• Verify that WLAN is enabled on
the measuring device and
operating device → 60.
WLAN communication disabled
–
Not connecting to Web server,
FieldCare or DeviceCare
No WLAN network available
• Check if WLAN reception is
present: LED on display module
is lit blue
• Check if WLAN connection is
enabled: LED on display module
flashes blue
• Switch on instrument function.
Network connection not present or
unstable
WLAN network is weak.
• Operating device is outside of
reception range: Check network
status on operating device.
• To improve network
performance, use an external
WLAN antenna.
