Units:
The action of this
loop, Agitation, is
measured in RPMs.
Decimal Places:
Press the appropriate button
to display values with 0, 1, 2
or 3 decimal places.
Limits:
Here you adjust the
high & low settings
for this specific loop.
When adjusted, the
scaling for the gauge
will also be adjusted
to reflect the high &
low limits selected.
Gains:
Proportional & Integral
values are what the
software uses to
calculate output based
on differences between

Changing these may
seriously affect your

If you think you may
have accidentally
changed the P&I values,
press the Factory Default
button to return to their
original settings.
(See Section 19.4 for
more information on P&I
