Error
register
Description
{Bit-name in error register}
Detection
only in lamp
operation
Corrective action
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 M
Ω
.
No
Check lamp wiring and insulation
resistance.
Bit 11
(0x0800)
{ZVS}
: the ELC detects switching
losses of the power semiconductors
and shuts down to prevent damages.
Possible causes are cracks in the lamp
feeder cable, defect lamp connectors
or internal problems.
Yes
External reasons might be
flashovers in the lamp circuit. Check
or exclude.
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.
Bit 13
(0x2000)
{Lamp Power Low}
:
lamp
extinguishes (e.g. lamp or lamp wiring
defect).
Yes
Replace lamp.
Check lamp wiring.
