Description
{Bit-name in error register}
Detection
only in
lamp
operation
Corrective action
Measurement
Bit 9
(0x0200)
{Measurement}: problems with
the internal measurement
circuits.
Yes
Check for short in lamp
circuit.
Earthfault
Bit 10
(0x0400)
{Earth Leakage Fault}:
insulation resistance between
lamp circuitry and earth gets
lower than 200kOhm (e.g. in
case of bad wiring on the lamp,
high air humidity, polluted
cables or connections).
In order to avoid an unwanted
reaction of the earth fault
control during faultless
operation, the insulation
resistance of the lamp cables
and all lamp connectors must
be greater than 10 MΩ.
No
Check lamp wiring and
insulation resistance.
ZVS
Bit 11
(0x0800)
{ZVS}: the ELC detects
switching losses of the power
semiconductors and shuts
down to prevent damages.
Yes
External reasons might be
flashovers in the lamp circuit.
VBSupply
Bit 12
(0x1000)
{Supply}: indicates problems of
internal low voltage supply due
to internal problems or low
mains voltage.
Yes
Check for low mains voltage.
Check 24V-supply.
PLow
Bit 13
(0x2000)
{Lamp Power Low}: lamp
extinguishes (e.g. cooling too
strong or lamp defect).
Yes
Reduce cooling or replace
lamp.
Check lamp wiring.
Slave
Bit 14
(0x4000)
{Slave}: error detected in slave
modul or faulty connection
between master and slave.
No Check internal wiring.
CanIntern
Bit 15
(0x8000)
{CanIntern}: interference in
modul-internal communication.
No Check internal wiring.
