BAT TEMP
Yes
Battery temperature reached
maximum
Allow battery to cool.
MOD TH
No
Alternating with charge
parameters – one or more
module in thermal fault – the
charge process continues –
the fault module(s) is (are)
displayed + red led flashing.
Check that the fan(s) is (are) working
correctly and/or that the ambient
temperature is not too high or or
whether there is poor natural
ventilation to the charger. If all
modules are in thermal fault a TH fault
will follow.
MOD DFC
Yes
Alternating with charge
parameters – one or more
module in DF1 fault – the
charge process continues –
the fault module(s) is (are)
displayed + red led flashing.
Check power modules. If all modules
in DF1 fault a DF1 error will follow.
DF ID
Yes
Blocking fault – one or more
modules are not compatible
with the charger
configuration (for example
24V charger with one 48V
module). This can happen if
the user replaces one
module with another one
with a different voltage
setting.
Use correct module(s).
No Battery balance fault Check battery cell voltages.
Tº
No High battery temperature
Allow battery to cool. Battery may
need service.
