VARIO2 Extreme 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 24VAC or DC
• Ensure telemetry wires are shorted out or valid telemetry input (zero volt
or Digital input 5V max) 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 page 20 for
specifications
• If longer cables used, ensure sufficient voltage is provided to allow for
drops across the cable
If OK…
Step 2: Illuminator Test
• If Illuminator has been operated in an ambient temperature greater
than +50°C check the ATC function is enabled
• 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 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 Digital
5v Max) is applied and correctly wired
