Step Operation Press Action
6
Change setpoint
during Hold
mode
or
to change the “HELD” setpoint if the ramp is
on “HOLD.”
However, the ramp time remaining is not
changed. Therefore, when returning to RUN
mode, the setpoint will ramp at the same rate
as prior to local setpoint changes and will
stop if the final setpoint is reached before
time expires.
If the time expires before the final setpoint is
reached, it will jump to the final setpoint.
7
End the Ramp When the final setpoint is reached, the
“R” changes to “H” in the upper display and
the controller operates at the new setpoint.
ATTENTION
Any time the local setpoint
is different from the final setpoint value and
the RUN/HOLD
key is pressed, the ramp
will start again.
