Test 016 - Color Wheel 1 (Continuous Cycle)
When test 016 is executed, color wheel 1 steps until it encounters the
sensor and then rotates continuously.
NOTE: This test will not function if the sensor is not found.
The position of color and gobo wheels in relation to the bulkhead is critical
in VL2B/VL2C luminaires. Alignment of the wheel to the motor shaft
MUST be correct. This is best done using a motor/sensor test unit at a
service center. If you have a bulkhead in which a wheel has slipped or has
come loose, send it back to a service center for evaluation.
This also applies to the sensor bracket. Using the test EPROM’s to adjust
the sensor position on the bracket is recommended, but the adjustment of
the bracket on the bulkhead is best left to technicians at a service center.
Be advised that some of the older AIRPAX motors may not start at the test
codes higher motor speed. This does not necessarily mean that the motor
is damaged. Try jump-starting the wheel by flipping it in the right
direction. The wheel should start up and run fine. If the wheel does not
start, send the bulkhead back to a service center for evaluation. Be careful
not to damage the wheel or hurt your finger.
Test 017 - Color Wheel 2 (Continuous Cycle)
When test 017 is executed, color wheel 2 steps until it encounters the
sensor and then rotates continuously. Failure is indicated if the wheel does
not move or stops at the sensor.
Test 018 - Gobo Wheel (Continuous Cycle)
When test 018 is executed, the gobo wheel steps until it encounters the
sensor and then rotates continuously. Failure is indicated if the wheel does
not move or stops at the sensor.
Test 019 - Continuous Cycle (Three Wheels)
When test 019 is executed, all three wheels rotate continuously.
Test 020 - Lamp Start
When test 020 is executed, the lamp will ignite. If the lamp is off, the
ignitor board will pulse until the lamp is lit or the switch setting is changed.
If the lamp is in standby mode (test 021), it will be returned to full
intensity. When the lamp is lit, arc power supply indicators LAMP ON,
START, and IPRES should be lit; SHORT and STANDBY should be out.
The hour meter should be running and the fan running on high speed.
