(400) Zero point / span setting
Value setting (vALU), Ratio setting (rAtE)
、
Operation setting (ACt),
or No setting (oFF) of zero point / span can be set. The default
when shipped is OFF.
Value setting: The lower limit (411) (stroke range between -20.0
and 60.0%) and the upper limit (412) (stroke range
between 40.0 to 120.0%) can be set. The default
value when shipped is (411) = 0.0%, and (412) =
100.0%. However, the lower limit (411) and the
upper limit (412) setting cannot be established
unless the following is satisfied.
Span to be set :
“(412) - (411)”
≧
60.0 %
(Ex) Select (200) = dir when
(410) = vALU, (411)=10.0 and (412) = 90.0
Ratio setting: Used when all valve stroke (incl. over travel) and
operation stroke are known. Input all strokes (0.1 to
999.9) to (FULL), then, input operation stroke (60%
to 100% of FULL value) to (USE). Then, select over
travel set side (0% or 100%) by (SidE).
