Cause
Input voltage on ' battery
DC input' too low.
Charging process
stopped/switched over to
solar.
Input voltage on 'battery
DC input' too high.
Charging process
stopped/switched over to
solar.
Input voltage on ' solar
input' too low.
Input voltage on ' solar
input' too high.
Temperature protection.
Internal temperature too
high.
Warning: internal
temperature threatens to
become too high.
Solution
When the input voltage has
risen sufficiently (first battery
charged again), the charging
process will be started
automatically.
The alternator outputs too
high a voltage. The charging
process is restarted auto-
matically when the voltage
has dropped sufficiently. If
necessary, have the alterna-
tor adjusted differently.
When the input voltage has
risen sufficiently again, the
charging process will be
started automatically.
When the input voltage has
dropped sufficiently again, the
charging process will be
started automatically.
When the converter has
cooled down sufficiently, the
charging process will be
started automatically. Try to
place the converter in as
cool an environment as
possible.
Check the fan and provide
adequate ventilation options.
Charging process is still
continuing. If the internal
temperature continues to
rise to the specified value,
the charging process will
stop. The message disap-
pears when the internal
temperature of the
converter has dropped
sufficiently.
