8.2 CIM 500 BACnet IP

You can detect faults in CIM 500 by observing the status of the two communication LEDs. See the table below.
8.2.1 LED status
CIM 500 connected to an LC 2XX.
Fault (LED status)
LED1 and LED2 remain off when the power supply
is connected.
LED2 for internal communication is flashing red.
LED2 for internal communication is permanently red.
BACnet LED1 is permanently red.

Possible cause
CIM 500 is fitted incorrectly in the Grundfos product. Check that CIM 500 is fitted and connected correctly.
CIM 500 is defective.
No internal communication between CIM 500 and
the Grundfos product.
CIM 500 does not support the Grundfos product
connected.
Fault in the CIM 500 BACnet IP configuration.
Error in firmware download.
Memory fault.
Possible cause
Configuration or wiring error.
The value is unavailable. A data value of 0xFFFF
does not necessarily indicate an error condition. It
means that the value is unavailable from the
controller.
The product is not configured to show the value or
lacks a sensor to read the value.
Remedy
Replace CIM 500.
Check that CIM 500 is fitted correctly in the
Grundfos product.
Contact the nearest Grundfos company.
Check that the rotary switch SW1 is set to 2.
Check that BACnet IP address configuration is
correct.
Use the webserver to download the firmware again.
Replace CIM 500.
Remedy
• Check the visual diagnostics on the BACnet
slave. Normal conditions are that the Grundfos
GENIbus LED (LED2) is permanently green and
that the BACnet IP LED (LED1) is off or flashing
green.
• Make sure that the cable between the BACnet IP
master and the BACnet slave is connected
correctly.
• Ensure that the slave IP address is configured
correctly, and that the correct slave IP address is
used in the BACnet master poll.
