ELC N6_N10-V3.1-09/11-GB subject to technical alterations
4.4 Dimming
Operation
After having reached nominal operation, the desired lamp power can be infinitely adjusted.
•
Lamp power is adjusted via control voltage (0 – 10 V) at the analogous SET VALUE
control input.
In this context, 0 V are tantamount to minimum and 10 V to maximum lamp power.
The adjustment of lamp power via the analogous SET VALUE control input is
only possible if a LOW signal is applied to the digital MIN and MAX control
inputs.
4.5 Standby
Operation
During longer idle times the ELC can be switched to standby operation. The lamp is operated
at minimum power but can be brought up to nominal power within a few seconds.
Standby operation is set as follows:
•
a HIGH signal at the digital MIN control input or
•
0 V control voltage at the analogous SET VALUE control input.
The warm-up time from standby operation to nominal operation depends on the lamp's
ambient conditions. If cooling is too intensive during standby operation, the acceleration time
is prolonged.
The adjustment of standby operation is only possible if a LOW signal is applied
to the digital control input MAX.
4.6
Switching off the Lamp
•
The lamp is switched off by applying a LOW signal to the digital START control input.
In order to avoid heat accumulation in the ELC, the operating voltage should be
left on for a few minutes. Before restarting, the lamp must be sufficiently cooled
down as it cannot be fired otherwise.
