Error Causes Solutions
Lamps obviously too bright or not bright enough Check whether a lamp with the right wattage is installed If necessary change the lamp or the ECG
The lamp fl ashes on and off The lamp has reached the end of its useful life and can
no longer be used in a stable state Change the lamp
The device switches off after some time in operation The ECG is being operated outside specifi cations Adjust luminaire design or environment
The ECG is being operated in a hot environment and
switches off in order to prevent irreversible damage Adjust luminaire design or environment.
To restart, power supply must be interrupted.
Mains voltage outside the permissible range Adjust luminaire design or environment
Lamp type not suitable for ECG (e.g. NAV with PTi) If necessary change the lamp or the ECG
Lamp does not ignite (for 2-lamp systems, neither of
them ignites) and no visible glow can be seen shortly
after switching on (the same occurs when the device is
switched on even after a minute of downtime and after
an internal device reset). • RCD or some other protective component in the system
has been triggered
• Has the maximum permitted number of electronic
control gears per automatic cut-out been exceeded
for the installation in the 3-phase network?
• Is it absolutely sure that the neutral conductor is
correctly connected to all the fi xtures and that it is
making proper contact?
• Is it possible that moisture has got into the luminaire,
causing a short circuit?
Check the mains side wiring and, where applicable,
the insulation consistency
Failure in the mains side wiring Check whether the mains input voltage, suitable for the
specifi ed area of application is actually present at the ECG.
Make absolutely sure that the neutral conductor is correctly
connected to all the luminaires and that it is making proper
contact. Check whether all cables have the correct connec-
tion in the terminals.
The irreversible surge protection in the ECG has been
triggered (the ECG is permanently damaged) Check whether the lamp is working using other lighting
outlets. If this is not the case, check the mains input voltage
to see whether it is within the specifi ed range. If the neutral
conductor is both properly connected and it is making
proper contact, then both the ECG(s) and lamp(s) must be
replaced.
Different lumen output levels between luminaires Lamps with different wattages/light colors have been
installed The lamp type and wattage must match the type indicated
on the ECG. For any particular application, the chosen light
color should be uniform.
The wiring between ECG and lamp is faulty; there may
be a contact problem Check the wiring on the lamp side for proper contact
Has the lamp wiring been installed according to the
indications on the ECG? Where necessary wire up the lamp according to the
indications on the ECG
The ECG is operating outside the specifi ed temperature
range and is trying to reduce the thermal load on the
lamp via power reduction control ("forced dimming") Check whether the ECG is operating above the specifi ed
temperature in the affected luminaires. Make structural
changes in order to lower the heat load on the device.
Problems with other electrical devices, especially with
radio or TV receivers Wiring problems See also the information in section 2.2.4.4. Cable layout
Other electrical devices or receivers have insuffi cient
resistance to interference Increase the distance between the luminaire and the
affected electrical device or receiver; where necessary
contact the manufacturer of the device.
