5.1 Mains voltage monitoring
The mains voltage (L1, L2 of connector X100) is monitored during lamp operation.
In case of continuous input undervoltage the lamp power is reduced by the ELC in
order to prevent an overcurrent on the input side (see output power reduction in
chapter 6).
In case of mains voltage dropouts the ELC may stop lamp operation to prevent
damage of the inverter caused by undefined supply conditions.
5.2 Warning messages
The bits in the [Warning Register] are divided into two groups:
 Group1-Nibble: the bits 0-3 represent critical operating conditions of the lamp. However
they won’t shut down the lamp.
 Group2-Nibble: If a bit in the Group2-nibble (bits 4-7) is set, the lamp cannot be started
or will be shut down during operation.
The bits of the [Warning Register] will automatically be reset as soon as the triggering status
has been resolved.
