Nightscanner question

Hi All,

Does anyone know if the Nightscanner has an over temp cut off, or similiar?

The reason I ask is that I have a one fitted on my JetBox which is approximately 18 months old and has been used only about 12 times. Last night I used it to recce a landing site and it switched itself off. It had been on for maybe 2 or 3 continuous minutes.

The circuit breaker hadn't popped and the operating switch had not moved, the bulb simply went out. I thought that it had blown. After stowing the light and leaving it for a few minutes, it worked again perfectly and continued to do so throughout the evening.

Any ideas? A gremlin maybe? Or it had overheated and shut off?

Joel

The one we had fitted to the 109 cut itself off after about 90 degrees of left or right slewing.

Veeany,

Is that normal, or a fault, because that would be consistent wih what I was doing at the time.

Mine also shuts down when slewed 90 L/R. Resumes illume when slew angle decreased. Our other similarly equipped aircraft also does so.
I wonder if there's a stop that can be adjusted, 90 degrees right is where I most use the light.

Hmmmmm,

It must be a design 'feature'.
I feel better that I don't have a faulty unit, if nothing else.
