Bit 0: The {Lamp Voltage Low}-bit is set if the burning voltage of the lamp 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.
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-Pin X1.1 of the
initialisation signal (see paragraph 3.4.2).
• {Init Signal Ok}=1 means 24 V on X1.1, the lamp may be ignited and
operated normally.
• {Init Signal Ok}=0 means 0 V on X1.1, the lamp cannot be operated.
To render the ELC operational again in case {Init Signal Ok}=0 the
initialisation signal on X1.1 has to be 24V and the start signal {Start Lamp}
has to be reset.
Bit 2, Bit 3 und Bit 6: {n/a} bits (not available) are reserved for future applications.
