Cause
A brief over-voltage may
occur when large electrical
consumers are switched off.
Constant over-voltage is the
result of an incorrect con-
nection voltage.
The compressor (driver's
cab) is tilted too far.
The system cannot measure
the battery voltage.
The battery voltage is only a
little higher than the set
shut-down value.
Display messages
Remedy
➤ Brief over-voltage: No
action required.
➤ If the display message
"HI" remains visible for a
longer period: Have the
vehicle electronics
checked. Make sure the
connection voltage is less
than 30 V.
➤ Once the compressor has
been returned to its
normal position, the
system can be switched
on again.
➤ Consult an authorised
workshop and have the
battery connection
checked.
➤ Recharge your vehicle
battery.
