Note:
Colors (CTO and CYM) will only auto recalibrate when the dimmer has been closed for 3
seconds.
Partial Recalibration
It is possible to recalibrate sections of the luminaire from a console. This allows greater flexibility and
speed by only forcing a recalibration on specific mechanisms. Partial recalibration values (on the
control channel) are as follows:
•
Hold DMX value 102 for 3 seconds then 0 recals color: Color wheel, CYM, CTO, Dimmer
•
Hold DMX value 114 for 3 seconds then 0 recals gobos: Gobo wheels and Index
•
Hold DMX value 128 for 3 seconds then 0 recals lenses: Edge, Zoom, and Shutter
•
Hold DMX value 140 for 3 seconds then 0 recals Dimmer and Strobe
Sensor Testing
Most mechanisms within the VL3500™ luminaires are equipped with either optical or magnetic
sensors. The VL3500™ luminaire 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:
•
The four color mixers will read high when the tab is in the optical sensor.
•
The fixed color wheel will read low when the magnet is at the sensor and high at other times.
•
The zoom and edge will read high when the sensor is closed, or the tab is in the sensor.
