COOLING AND NOISE CONTROL
Cooling fan speed can be set to maximum () or thermostatically regulated () via
→. When set to , fans run no faster than is necessary, giving reduced noise levels.
At the convection cooling setting
→→, fans are shut down completely whenever
convection cooling alone can control fixture temperature. If convection cooling is not sufficient, fans run at
thermostatically regulated speed until convection cooling is possible again. As this setting gives totally silent
cooling while the lamp is blacked out, dimmed to a low level or when ambient temperature allows, it is
recommended for minimum noise levels.
SOFTWARE UPLOAD
The upload mode command (→) prepares the fixture for a software update. This command is
not normally necessary, as upload mode is engaged automatically by the uploader.
LED indicators
The four LEDs next to the digital display panel give the following information:
• Ready - lights when the fixture has reset and is ready for use.
• Lamp - lights when lamp power is applied from the DMX controller, regardless of dimming intensity. If this
LED is lit but no light output is present, the mechanical shutter may be closed, the intensity may be
dimmed to a very low level, the lamp may have blown, or there may be a problem with the lamp power
circuits.
• DMX - lights when the fixture is receiving a valid DMX signal.
• Service - blinks when the fixture is in factory service mode. For factory use only.
