AXIS T90B Series

•Basics

-Check the LED status indicator. See LED Indicators.

-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 difficult to see Infra-Red lamps working in high brightness conditions.

-Make sure that the power cable is within the specified 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 insufficient light on the scene.
