Display message Bit set in
error
register
Description
{Bit-name in error register}
Detection
only in
lamp
operation
Corrective action
DC Link
Bit 0
(0x0001)
{DC-Link-Undervoltage}:
internal dc link voltage is low
due to low mains voltage, blown
internal fuses or other defective
parts inside the ELC.
Yes
Check fuses
Check mains voltage
Consider charge time
Mains volt
Bit 1
(0x0002)
{Mains Voltage Low}: input
voltage measurement detects
mains voltage drop or
fluctuations (for shut down
voltage see chapter 6).
Yes
Check connections
Check mains voltage
Fan error
Bit 2
(0x0004)
{Fan Error}: malfunction of one
or more of the three ELC-fans
(one main fan, two internal),
detection via speed control.
No for
internal
fans.
The main
fan is only
running
during
lamp
operation
Check for:
ball bearing defect
tight connection of front
hood (correct engagement
of connector between
front hood and main
board)
corroded cable connection
on entry of the fan
blocked rotors
squeezed cables
Change fan or remove cause.
Temp high
Bit 3
(0x0008)
{ELC Temperature High}:
ambient or internal
temperature too high.
No
Check ambient temperature
and fans of cabinet (direction
of air current, change filter
mats).
Internal
Bit 4
(0x0010)
{Internal}:
problems of
internal communication
between controllers or failed
“self-check” of the controllers.
No
Switch off and on the 24V
supply.
Bus error
Bit 5
(0x0020)
{Bus Connection Error}: field
bus connection fails during
lamp operation.
Yes
Check bus termination and
connector contact.
X6CA failure
Internal communication fails.
No
Send back for repair by
manufacturer.
Over volt.
Bit 6
(0x0040)
{Overvoltage}: short peak
overvoltage on the lamp
exceeds nominal ignition
voltage during ignition or
operation due to an internal
problem of the ELC or damaged
cables on lamp circuitry.
Yes
Check lamp wiring concerning
insulation defects.
Lamp v.hi
Bit 7
(0x0080)
{Lamp Voltage High}: the lamp
voltage exceeds a threshold
critical for the ELC. Usually the
lamp type is not correct.
Yes
Check lamp type and lamp
connectors/sockets, switch
lamp.
Over curr.
Bit 8
(0x0100)
{Overcurrent}: internal
overcurrent.
Yes
Check for short in lamp
circuit.
