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 lamp voltage falls below its minimum
(set by the manufacturer). This bit will be reset if the lamp voltage exceeds the
minimum.
Bit 1
:
The
{Run Up Long}
-bit is set if the warm up of the lamp takes longer than
expected. 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).
Bit 4
:
The
{Safety Relay Open}
bit is set if the safety relay is not closed (e.g. on
emergency shutdown). There are two different cases:
If in register
[Lamp Control]
{Start Lamp}
bit is 0, the
{Safety Relay Open}
bit is
automatically reset as soon as the safety relay is closed.
During lamp operation (
{Start Lamp}=1
in
[Lamp Control]
) the
{Safety Relay
Open}
bit remains set and the lamp will be shut down by the ELC. In this case
{Safety Relay Open}
will only be reset if
{Start Lamp}
in
[Lamp Control]
is reset
and the safety relay has been closed.
Group 2:
Lamp operation not
possible
Group 1:
No shut down
