Proline Promag P 500 HART Diagnostics and troubleshooting
Endress+Hauser 147
For output signals
Error Possible causes Solution
Signal output outside the valid
range
Main electronics module is
defective.
Order spare part →  171.
Signal output outside the valid
current range
(< 3.6 mA or > 22 mA)
Main electronics module is
defective.
I/O electronics module is defective.
Order spare part →  171.
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 →  134.
No write access to parameters Current user role has limited access
authorization
1. Check user role →  75.
2. Enter correct customer-specific
access code →  75.
No connection via HART protocol Communication resistor missing or
incorrectly installed.
Install the communication resistor
(250 Ω) correctly. Observe the
maximum load →  179.
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 →  82.
Incorrect setting for the Ethernet
interface of the computer
1. Check the properties of the
Internet protocol (TCP/IP) →  78.
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 →  78
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 .
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.
