5.3 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.

Bit 0
:
The
{Lamp Voltage Low}
-bit is set if the actual lamp voltage is lower than
the threshold voltage given in chapter 6. A possible reason is a strong lamp
cooling especially in dimming operation. This could cause a long run up time
to regain the nominal power.
Please consider that the ELC cannot distinguish lamps of different nominal
voltages. If the ELC is used on purpose to operate a lamp with a lower
nominal voltage the bit will be set although full lamp voltage is reached.
This bit will be reset if the lamp voltage exceeds the threshold voltage.
Bit 1
:
During run-up the lamp power normally increases to the desired lamp power
(Register
[Power Set Value]).
The
{Run Up Long}
-bit is set, if 95% of the
required lamp power are not reached within 3 min. Possible reasons are an
incorrect lamp type or excessive cooling of the lamp.
Reset occurs as soon as the
{Start Lamp}
-bit in register
[Lamp Control]
is
set to 0 (the lamp being thus actively shut down by the operator via the
PROFIBUS output data).
Group 2:

possible
Group 1:
