HI
detected a brief or con-
stant over-voltage.
The system has

LO
may briefly appear.
Cause
Connection voltage is too
low. The battery capacity
is not sufficient to operate
the system.
A brief over-voltage may
occur when large electri-
cal consumers are
switched off. Constant
over-voltage is the result
of an incorrect connec-
tion voltage.
The current power
requirement of the com-
pressor is too high.
The compressor (driver's
cab) is tilted too far.

Remedy
➤ Brief under-voltage: No
action required.
➤ The system switches it-
self off: Charge the ve-
hicle battery or check if
the battery monitor has
been correctly set.
➤ Brief over-voltage: No
action required.
➤ If the display message
"HI" remains visible for a
longer period: Check
the vehicle electronics.
Make sure the connec-
tion voltage is less than
30 volts.
➤ The brief overload is
compensated by the
system by switching off
the compressor. The
compressor starts up
again after a short time.
➤ Once the compressor
has been returned to its
normal position, the
system can be switched
on again.
