ELC X-Series-V1.3-09.16-GB
subject to technical alterations
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.
Bit 5
:
If the ELC cannot ignite the lamp the
{Lamp Ignition Failed}
bit will be set and
remains in this status as long as
{Start Lamp}=1
in
[Lamp Control]
. The
{Lamp Ignition Failed}
bit is reset as soon as
{Start Lamp}
in
[Lamp Control]
is reset.
Bit 7
:
The
{Init Signal Ok}
bit reflects the status of the
Init-Signal-Pin
X806.3 of the
initialisation signal (see paragraph 3.3.2).
•
{Init Signal Ok}=1
means 24 V on X806.3, the lamp may be ignited and
operated normally.
•
{Init Signal Ok}=0
means 0 V on X806.3, the lamp cannot be operated.
To render the ELC operational again in case
{Init Signal Ok}=0
the
initialisation signal on X806.3 has to be 24V
and
the start signal {Start Lamp}
has to be reset.
