Hi, Barry,
Sorry, this fell in a crack because the real answer is I
DON'T KNOW. I was hoping I'd have time to play a bit with
it, but now I have some Dragons to go through so I don't
know when/if I can get to this.
If you find out anything, I can post it with my APR
manuals.
Cheers,
Richard

Greetings
Richard,
I
hope you don’t mind me contacting you, but you appear to
be the oracle on the APR machines so thought you may be
able to help me with an issue regarding the flutter
damping arm (tension control guide arm) setup?
The
issue I have is I’m wondering if the manual is incorrect
(see attached) as I am having difficulties setting this
up as the manual states.
I
have adjusted the HES board position to give me the same
voltage when moving the arm from left to right, &
adjusted RV1 for a total swing of 10.25V giving -5.125V
when fully left & +5.125V when fully right. This
seems okay, but the next step in the manual says to goto
TP.B & move the arm fully right & adjust voltage
to 0V using RV2. This is not possible as the voltage
swing is the opposite way round – I can bring the
voltage down to approx. 0.4V at the left stop with
voltage rising towards the 10V as moved towards the
right stop. This is with the RV2 pot at it’s end stop
& is the other way around to what the manual states.
I
have checked all the components on the board &
replaced the op-amp but everything seems okay, just the
output is the opposite way to what is stated in the
manual + I can’t bring the lowest voltage down below
0.4V, but it states must be 0V ±0.25V but pot RV2 is at
it’s end stop.
Any
ideas – manual error or other issue?
Cheers,
Mark...
