indicates the cause of the error. Therefore the following sequence is performed which is repeated as long as the unit is
not reset.
Sequence:
Stray Light Monitoring
The stray light check is performed at the end of the pre-purge timer for the duration as mentioned in the table of timings.
Low-voltage protection
at 220 / 240V (110 / 120V) nominal usage
The mains voltage has to be more than 187V
eff
(94V
eff
) in order to allow the unit to perform a start-up.
The mains voltage is not only mentioned in the start-up phase but also permanently during operation. If the voltage drops
below <160V
eff
(80V
eff
) during start-up or run time the control box goes into lock-out mode. If the voltage rises again, the
control box performs automatically a start-up as soon as the mains voltage is >187V
eff
(94V
eff
).
