6. Fault finding

6.1 PROFINET IO

You can detect faults in a module by observing the
status of the two status LEDs. See the tables below.
CIM 500 fitted in a Grundfos product or CIM 500
fitted in a CIU 500
Ensure that SW1 is in position "0" to select
PROFINET.
Fault (LED status)
1. Both LEDs remain off when
the power supply is
connected.
2. LED1 remains off.
3. LED2 is flashing red.
4. LED2 is permanently red.
5. LED1 is permanently red.
6. LED1 is flashing red, 3 Hz.
7. LED1 is pulsing red, 0.3 Hz.

Remedy
Check that the module is fitted and
connected correctly.
Replace the module.
Replace CIU 500.
Set the switch to "0".
Check that the module is fitted
correctly in the Grundfos product.
• Check the cable connection
between the Grundfos product
and CIU 500.
• Check that the individual
conductors have been
connected correctly, for
example not reversed.
• Check the power supply to the

• Restart CIM 500. Use the
RESTART button on the
webserver, or power cycle the
product. See section
PROFINET IO configuration.
• Check that the PROFINET IO
IP address configuration is
correct. Check the device name
in CIM 500 and PROFINET IO
master.
• Check that the right GSDML file
is used.
• Check the cables.
• Check that the master is
running.
Use the webserver to download
the firmware again. See section
