Maxem does not connect to the online back end
•
Control that Maxem network connection is active. If there is a data connection, a LED
burns orange on the LAN port, green or it is off. If there is activity on the connection,
an orange LED is blinking.
•
Control if there is an active Internet connection on the connected router.
•
Control whether the connected UTP cable is correctly connected with the help of a
cable tester.
•
Make sure that a DHCP connection can be made to Maxem from the network.
•
Make sure that Maxem can do DNS requests through the network to connect to the
back office.
•
It is possible to place Maxem in a DMZ (demilitarized zone) on a separate VLAN.
•
Restart Maxem by turning it off and on. Any problems with the IP addressing can thus
be fixed.
Auto configuration is not successful
•
RS485 connected charging station: control whether the RJ10 (4P4C) connector is well
crimped into the RS port of Maxem. See Annex 3 how to crimp RJ connectors the best.
•
Ethernet Connected charging station: Make sure that green and blinking orange LED
in the charging station are on for an active connection with Maxem. If this is not the
case, there is a possible error in the installed UTP cable.
•
Restart the charging station by putting the voltage off and on again.
•
Make sure the correct firmware is placed on the charging station and that is
compatible with Maxem. An employee of Cohere can help.
The charging station is not detected or not correctly detected
•
Turn off Maxem. Wait for 10 seconds.
•
Then turn on Maxem. If there is a charging station, switch the group of the charging
station off and on again. The autoconfiguration will run again.

Annex 1 - Troubleshooting
The car does not start during charging
•
Perform a reboot of the group of the charging station in the meter box (turn off the
group, wait for 10 seconds, and then turn on the group again). Make sure that the
charging cable is not connected to the car.
•
An authorization problem for ICU charging stations may occur, which prevents the
charging station from giving a “permission” to start a charging session. An employee
of Cohere can help.
The measurements of the power supply are not logical
•
In case the solar panels are available, turn off the group.
•
Make sure the power supply (socket) of Maxem is connected to L1.
•
Make sure that each current coil is connected to the phase corresponding to the
labels of the cable splitter.
•
Make sure the current coils are directed correctly. The arrow on the current coil
follows the current direction of the net to the groups of the house.
•
Make sure the cable splitter is connected to Maxem CT1 port.
