Check input voltage which comes to every
section of this terminal board between R-S, S-
T, and T-R.
When there is no voltage even at one point,
original power is in open phase.
There is problem in control board.
Cement resistance is damaged
When switching the motion of the backgauge

momentarily and this cement resistance can be
damaged. In this case, replace P.C.B.
LEDs from No.1 to No.6 do not turn on.
When LEDs from No.1 to NO.6 showing
operation of knife, clamp, and backgauge turn
on normally, input signals are OK. If there is
no problem in output motor, SSR may has a
problem. Replace P.C.B.

Replace belt with a new one.
As for high speed belt for S/N 103001 or
above, a new wider belt is used which is hard
to overturn. To attach this wider belt to a
previous machine, gauge base and motor base
also must be replaced.
