Reading fault messages

Fault messages have priority over all other displays. If a fault
occurs in the solar system, the solar system switches itself
off. The display of the solar charger displays a fault code in
place of the basic display. A plain text display explains the
displayed fault code.
If multiple faults occur at the same time, the display shows
the corresponding fault codes for two seconds each in se-
quence.
▶ If the solar charger displays a fault message, contact
your approved competent person.
Note
Status messages about the condition of the
solar system can be called up using the Live
Monitor (→ Page 12) function.
5.1.1 Fault message
Fault messages appear on the display approx. 20 seconds
after a fault has occurred. If a fault is present for at least
three minutes, a fault message is recorded in the fault
memory of the solar control.
Note
Only a competent person can eliminate the cause
of the faults described below and delete the fault
memory.
