5 Troubleshooting
Issue Cause Connection
The CM does not appear in the “My
Devices” list.
The CM is in sleep mode. Shake the CM and wait for the blue
LED to blink or wake the CM by
use of a magnet, see “Section 5.1
Magnet functionality”
The CM does not wake up when
performing the wake instructions.
The CM software may be suspen-
ded.
Perform a software reboot by use
of the magnet, if the reboot does
not correct the issue, perform a fac-
tory reset by use of a magnet, see
“Section 5.1 Magnet functionality”
The CM does not respond to a
magnet, but is connectable via the
application.
Make sure the magnet is placed
correctly, at the QR code on the
CM.
If the problem persists, try a differ-
ent type of magnet.
During Setup, I successfully woke
up the CM, but now it does not ap-
pear in the “My devices” list.
The CM returns to sleep mode after
15 minutes, if no application con-
nection has been made.
Perform a wake instruction again.

Connection
Reboot
Factory reset
In case the CM becomes unconnectable via the Alfa Laval Condition Monitor application the CM
firmware can be restarted by holding a magnet to the QR code located on the CM.
The magnet HMI describes how to operate the magnet, the magnet menu is divided into colors. Blue
for connection, yellow for reboot and red for factory reset.
If a reboot is wanted, hold the magnet to the QR code on the CM. The CM will indicate the presence
of the magnet by flashing the green LED and then proceed through the magnet menu. When the CM
starts to flash yellow remove the magnet, if the reboot command has been confirmed the CM will
respond with three yellow LED flashes.
In the event a firmware reboot does not alleviate the problem, the magnet can also be used to
perform a factory reset of the CM, this will delete all stored data and completely reset the CM.
