8. Disposal
This product or parts of it must be disposed of in an
environmentally sound way:
1. Use the public or private waste collection service.
2. If this is not possible, contact the nearest
Grundfos company or service workshop.
The crossed-out wheelie bin symbol on
a product means that it must be
disposed of separately from household
waste. When a product marked with this
symbol reaches its end of life, take it to a
collection point designated by the local
waste disposal authorities. The separate collection
and recycling of such products will help protect the
environment and human health.
Fault (LED status) Possible cause Remedy
1. The service LED (LED1)
remains off when the power
supply is connected.
a) No power supply to the CIU
1XX. Check the power supply to the CIU
1XX.
b) The CIM 1XX is defective. Replace the CIM 1XX.
2. The service LED (LED1) is
permanently on. a) The CIM 1XX is defective. Replace the CIM 1XX.
3. The service LED (LED1)
flashes when the power
supply is connected to the
CIM 1XX, turns off, turns on
again and remains
permanently on.
a) The CIM 1XX has no
application software
(application-less).
Try to download application
software via a LON installation tool
such as LonMaker.
b) The CIM 1XX is defective. Replace the CIM 1XX.
4. The service LED (LED1)
flashes every second. a) The CIM 1XX has not been
installed. Install the CIM 1XX by means of a
LON installation tool such as
LonMaker.
5. The Grundfos product does
not react to changes of
settings, and the readout from
the LON network is incorrect.
The LED for internal
communication (LED2) is
permanently red.
a) The CIM 1XX does not
support the Grundfos product
connected.
Contact the nearest Grundfos
company.
b) The LON application may be
wrong, for instance CIM 110
software where CIM 100
software is required.
Download correct software via a
LON installation tool such as
LonMaker.
