Err 18 Generator ON
The kV value
changes via the
kV+ or kV- but-
ton.
The change in volt-
age level in the
capacitor bank takes
too long
(> 0.5 s/V). See also
"Err 17".
• Check whether S10 on D7 is
switched off.
• Check if any of the capacitors in the
capacitor bank are defective. The
output energy may be consumed
by a defective capacitor (see
section "Battery circuit and power
transmission unit").
• Check the signals
"CHARGE_HIGH", "DISCHARGE"
and "CHARGE_LOW" (see page
130**). Check fuse U1 on D7, U5
and U8 on D8 and resistors R100
and R101.
CAL 19 Generator goes
ON before the
ready lamp
glows.
The leakage current
in the capacitor bank
is too large.
The measurement is performed dur-
ing charging at 150 V DC. Charging
is interrupted for 5 s.
If the voltage drops by more than 1.6
V, a message will be displayed.
See also "Err 17".
• In cases where the generator has
not been operated for several
months, the leakage current in the
capacitors will have increased. Use
the formation program P06 (see
section "P06 - Capacitor
formation").
• If the unit was in regular use before
the message occurred, the error
may result from increased leakage
current or a damaged capacitor
(see section "Battery circuit and
power transmission unit").
• Check the capacitance in the
capacitor bank (see section "P03 -
Capacitor bank and charging test"
and page 130**).
