Hi All,
maybe someone can help me to bring my TU81 back to life again.
I have checked the following, before turning on:
- All capacitors on the Mail Power Supply and the one below the vacuum
pump are fine
> OK
- Voltages check
> OK
- Fuses
> The Fuse for the diagnostics power connector was burned: changed
Problem is, that the "Logic Off" is constantly illuminated, after
turning on.
I had a look into the Tx81 Pathfinder documentation, and checked the
following.
- Check if Blower is running
> OK
- Disconnecting all DC connectors
> Same result
Pathfinder tells me changing the power supply.
I hear only an relay clicking when turning on the Power Supply, also,
when nothing is connected, in this time the "Logic Off" light blinks one
time.
I think, that the power supply checks itself that the voltages are OK,
and that this fails.
Any hints or tips?
Many Greetings
Ulrich
