Polar 92 EMC - Spec for L1 Inductor on TAM card

[Grimm_Matt]

I have been having issues with an Error 85 Problem I have been trying to track down. While doing so I noticed the L1 inductor on my TAM card is fried. I am not sure if this is cause of the Error, but would like to swap in a new inductor. The damage to the part has made reading the specifications difficult. It looks like it may say 100 uH Does anyone have the exact specification for this component?

Looks like inductor is 100 uH

Hi Sir:

Is very interesting, about his problem.

However, the fact that inductor is fried, is very important and carefully, because, you can have a short circuit, in your electronic board
TAM, by some electronic components, like capacitor, diode, etc. You must test very carefuly...

By other side, you must have in serious consideration, the Measure of Regulated Power Supply, like: PS5+ PS24, in tolerance, since, this can provide, unstable voltages, for your circuits, TTL, CMOS, in your electronic boards.

Good look.

Thank you for the reply,

I am also concerned of potential cause of the failure. LED V2 on the card seems to flicker at times, which is why I checked the card. Though the measurement system has performed fairly consistently, occasionally it will miss the entered measurements and the numbers flash briefly. I tried to check for shorts on the card and could not find any. Voltages are steady around 5.11 and 24.13.

There is not much information on the Length Measuring System in my service manual. Does it need to be cleaned occasionally or require other maintenance?

Hi Sir:

How you are mentioned, You are wrong voltages in : PS5+ PS24!!!!, they are out of tolerance, And must be replaced.

In order to work the circuists: TTL+ CMOS.
