subject to technical alterations
5.4.2 Display messages and trouble shooting
Display message
Bit set in Error
register
Description
Corrective action
ELC ready
-
ballast is ready for operation
Display is off
-
no 24V supply or display defect
Check 24V supply, switch off and on again.
DC Link Undervoltage Error
Bit 0
(0x0001)
internal dc link voltage is low
•
Check fuses
•
Check mains voltage
•
Consider charge time
Mains Voltage Error
Bit 1
(0x0002)
input voltage measurement detects mains
voltage drop or fluctuations
•
Check connections
•
Check mains voltage
Fan Error
Bit 2
(0x0004)
fan stops
Check if there are a blocked rotors or
squeezed cables
Overtemperature Error
Bit 3
(0x0008)
ambient or internal temperature too high
Check ambient temperature and fans of
cabinet (direction of air current, change
filter mats)
Internal Error
Bit 4
(0x0010)
problems of internal communication
between controllers or failed selfcheck of
the controllers
Switch off and on the 24V supply.
Bus Error
Bit 5
(0x0020)
field bus connection fails during lamp
operation
Check bus termination and connector
contact
X6CA failure
internal communication fails
Send back for repair by manufacturer
Overvoltage Error
Bit 6
(0x0040)
the lamp voltage exceeds nominal ignition
voltage during ignition or operation
Check lamp wiring concerning insulation
defects
Lamp Voltage High Error
Bit 7
(0x0080)
actual lamp voltage exceeds a threshold
critical for the ELC
Check lamp type and lamp
connectors/sockets, switch lamp
Internal Error
Bit 8
(0x0100)
Overcurrent: indicates an internal
overcurrent
Check for short in lamp circuit.
Internal Error
Bit 9
(0x0200)
Measurement: appears in case of problems
with the internal measurement circuits.
Check for short in lamp circuit.
Earthfault Error
Bit 10
(0x0400)
insulation resistance in lamp circuitry gets
lower than 200kOhm (e.g. in case of bad
wiring on the lamp, high air humidity,
polluted cables or connections)
Check lamp wiring and insulation resistance
Internal Error
Bit 11
(0x0800)
ZVS: gives notice if the power switches are
not working in zero voltage switching mode.
External reasons might be flashovers in the
lamp circuit
Internal Error
Bit 12
(0x1000)
Supply: indicates problems of internal low
voltage supply
This might happen with low mains voltage.
Check 24V-supply.
Lamp Power Low Error
Bit 13
(0x2000)
lamp extinguishes (e.g. cooling too strong
or lamp defect)
Reduce cooling or replace lamp.
Check lamp wiring.
