AXIS T90B Series
• Basics
- Check the LED status indicator. See LEDIndicators.
- Check polarity of lamp connection: red = +ve,
black = -ve
- Ensure power is 12-24 V AC or DC
- Ensure telemetry wires are shorted out or closed
contact input (zero volt) is applied
- Check photocell is working. Cover photocell fully,
light should turn on. It is sometimes difcult to
see Infra-Red lamps working in high brightness
conditions.
- Make sure that the power cable is within the
specied distance.
• Lamp Test
Note
Use the appropriate multimeter depending on how
the illuminator is being powered (AC or DC). Cover
the photocell fully (or disable the photocell using the
optional remote control) and make sure the telemetry
wires are shorted out or closed contact input (zero
volt) is applied.
- Check that the current is being drawn. The amount
of current will depend on the power setting of the
illuminator.
• Set up Camera, Lens and Illumination
- Make sure the power is set to maximum.
- Check the orientation of illuminator and make sure
it is pointing in the correct direction
- Check angle of the diverging lens. A too narrow
angle may cause hot spots and the aperture of the
camera lens to close down. A too wide angle may
cause insufcient light on the scene.
