LED halo displays red
Charger(s) have a blink-

The measured
resistance value is not
60 Ohms
• This is the default color on a Power Sharing system
at start up. If it lasts more than 30 seconds, check to
ensure that the Power Sharing system has been properly
configured. If not, correct the system configuration and
wait for up to another 30 seconds.
• Make sure the total number of chargers includes the

Primary charger.

• Make sure the "Maximum current per system (phase)" is
set correctly.
• Poor contact on the communication cables. Check that
all the communication cables are properly connected on
the chargers (see the
• Incorrect resistance value between communication lines.
Turn off the power to all the chargers (circuit) and measure
the resistance between the CAN-H and CAN-L. If the
measurement is not at or around 60 Ohms, check the wiring
connections per the "Wiring" section above.
• If the resistance value is higher than 60 Ohms, there is
only one charger in the T configuration.
• If the resistance value is lower than 60 Ohms, there are
more than two chargers in the T configuration.
• The Power Sharing system must have both the first and
last chargers in the daisy chain set to the T configuration.
All the other chargers must be in NT configurations.
• If the Primary charger is not placed at either of the ends
and is placed at any other position in the daisy chain, it
should be in the NT configuration.
• If the resistance value is not near 60 Ohms but the
configuration is correct, there may be a charger fault. To
check for a fault:
Remove the CAN cables from all chargers.
Change the switch position to T for all chargers.
Check the resistance value for each charger.
• The T chargers should have a 120 Ohms resistance
between lines.
• The NT chargers have open lines or zero resistance.
