8.7 Distillation with timer
8.7.1 Setting the set point and start
 Choose timer mode (if it is not already active)
[MENU] ð [MODE] ð [TIMER] ð [PROG]
 Define distillation time. Use [é] to increase the actual value
and [ê] to decrease the actual value. Use [OK] to confirm
the desired value.
 Define set point. Use [é] to increase the actual value and
[ê] to decrease the actual value. Use [OK] to confirm
the desired value.
 Store Program (if desired) [OK]
Now, the controller is ready. Use [RUN] to start the controller.
[STOP] ends the distillation and ventilates the apparatus
(unless you have configured otherwise).
8.7.2 Possible interventions into the regulating
process
 Increase the system pressure or interrupt pressure drop in
the start phase ð [Pé]. The apparatus goes into the
hold mode and regulates back to the actual value. If
necessary, the apparatus is partially ventilated. [ESC] it
puts back into the RUN mode with the original set point.
[OK] puts its back into the RUN mode with the new set
point.
 Reduce system pressure ð [P Set] ð [Pê]. The
apparatus goes into the hold mode and regulates further
to the actual value. If necessary, the apparatus is partly
ventilated. [ESC] it puts back into the RUN mode with
the original set point. [OK] puts its back into the RUN
mode with the new set point.
 Change hysteresis ð [dP]. Use [é] to increase the actual
value and [ê] to decrease the actual value. A = Automatic
hysteresis. Confirm desired value with [OK]. [ESC] puts
it back into RUN mode with the original value.
 Changes into the manual mode ð [Man]. The timer
function is turned off.
