VARIO2 Troubleshoot
Ensure all tests are undertaken by a qualified, trained engineer. Ensure safe working
practices are followed at all times.
Step 1: Basics
•
Check polarity of illuminator connection red=+ve, black=-ve
•
Ensure power is 12-24V AC or DC (For Vario 16 variants : 24V AC or DC only)
•
Ensure telemetry wires are shorted out or valid telemetry input (zero volt or TTL)
is applied and correctly wired
•
Check photocell is working. Cover photocell fully, light should turn on if valid
telemetry input. It is sometimes difficult to see Infra-Red illuminators working in
high brightness conditions.
•
Ensure power supply is suitably rated to product - check specifications table
•
If longer cables used, ensure sufficient voltage is provided to allow for drops
across the cable
If Ok...
Step 2: Illuminator Test
•
Check current is being drawn – amount of current will depend on power setting
of unit. Please note – use appropriate multimeter depending on how the unit is
being powered (AC or DC)
•
To test this you must ensure photocell fully covered (or disabled using optional
VARIO remote controller or manual control buttons) and ensure telemetry
wires are shorted out or valid telemetry input (zero volt or TTL) is applied and
correctly wired
Step 3: Set up camera, lens, and illumination
•
Check model number to Raytec performance specification to ensure required
distance is achievable;
•
Check unit is set to max power
•
Check orientation of unit and ensure it is pointing in correct direction
•
Check angle of unit (Interchangeable lens) – Too narrow may cause hot spots
and the aperture of the camera lens to close down. Too wide and there may be
insufficient light on scene and light going where it is not needed.
•
Check the LED status indicators for the status of the illuminator.
