Luminaire Self-Tests
The luminaire is capable of running self tests by using the TEST menu functions. For detailed
instructions regarding the luminaire’s self-test function, refer to the VLX3 LED Wash Luminaire
User’s Manual (02.9703.0001).
Calibration Sequence
The following is an outline of the luminaire’s standard calibration sequence:
Phase 1
• Tilt
• LEDs Off
• LED Upload
Phase 2
• Zoom
Phase 3
• Pan
Sensor Testing
Most mechanisms within the VLX3 luminaire are equipped with either optical or magnetic sensors.
The VLX3 master control board (MCB) has labeled test points for reading DC voltages at each sensor.
Testing is best performed with a digital voltmeter for sensor readings or an Oscilloscope for pan/tilt
encoder readings. The values can be used to determine whether a circuit is opening correctly or needs
further troubleshooting.
Guidelines:
• The values will change depending on whether the sensor reading is Open or Closed.
• The values will be different depending on the type of sensor: optical or magnetic.
• As a general rule, if a change occurs from 5v to 0v or visa versa, then it is working.
• An Open reading occurs when the sensor is not aligned - tab not at sensor (typically a non-zero
DMX value).
• A Closed reading occurs when the sensor is aligned -tab in or at sensor (typically a zero DMX
value).
• Optical sensors read high when the sensor is Closed.
• Magnetic sensors read Low when the sensor is Closed.
• High value - 5 volts (typically 4.9 volts).
• Low value - 0 volts, or up to approximately 0.2 volts.
Notes regarding specific mechanisms:
• Tilt sensor reads high when the tab is in the sensor. The mechanism calibrates to the edge and its
tab covers 50% of travel. Pan and tilt encoders are best read with a scope to read the encoder ticks.
