• The system does not
have the correct time.
– Configuration error, no time
server configured.
– The time server is
configured but is offline.

as time source but the time

• An advanced charger
does not come online in
the Device Manager in a
system with “Service
discovery” enabled.
– The charger parameters for
Service Discovery are not set.
– The service discovery
parameter “Domain Name” is
not unique in the IP network
domain.
– The advanced charger and
the Device Manager are
located in two separate IP
networks that prevents the
service discovery request.
Use PDM to configure the Service
Discovery domain in the charger
to the same value that is set in
Unite CM.
Use PDM to reconfigure the
charger to another service
discovery domain. Make sure
that the Unite CM is configured to
use the same value
Use PDMPDM to disable service
discovery in the advanced
charger and to set the IP Address
to the Unite CM.
• An advanced charger
does not come online in
Device Manager in a
system with “Service
discovery” disabled.
The charger is configured to
connect to a Device Manager
with a “Domain ID” that is not
used.
Use PDM to disable service
discovery in the advanced
charger and to set the IP Address
to the Device Manager.
• The charger logs out
immediately after log in
and does not come online
again.
The charger is already saved
in the Device Manager that
the administrator wants it to
use. The Advanced Charger
parameter in the desired
Device Manager is pointing to
another Device Manager
(service discovery or IP
address) which causes the
charger to logout and connect
to another Device Manager
after completed
synchronisation.
– Before connecting the
advanced charger to the LAN,
make sure that if the advanced
charger is saved in the desired
Device Manager it has
parameters that points to the
correct Device Manager.
– Delete the saved charger from
the Device Manager before
connecting the charger to the
LAN.
