5.4 Change volume [S2].
The (remaining) volume applies to all volumes to be filled [S1].
The signal [S2] can switch a second valve at a specified residual volume. This valve
can be used, for instance, to switch over from a large flow rate at the start of a filling
process to a smaller flow rate for the remaining volume [S2].
Example: Filling volume 50.0 L. It should be filled through 2 valves.
Filling should be done more slowly with a residual filling volume of 3.5 litres, as the
liquid could otherwise overflow out of the container.
Valve 1 is controlled by [S1] and is responsible for the lower flow rate.
Valve 2 is controlled via the S[2] signal and is responsible for the higher flow rate.
The filling volume [S1] of 50.0 litres is set to BC 0 (memory location 0).
The volume [S2] is set in the SET group to 3.5 litres, as the setting applies to all
volumes to be filled [S1].
Both signals [S1] and [S2] are actuated once the Start button has been pressed and
both valves open simultaneously. The display runs backwards from 50.0 litres. The two
symbols for [S1] and [S2] flash to symbolise that they are currently active. Valve 2 clos-
es when a volume of 3.5 litres remains [S2], while S1 remains open until everything has
been decanted.
5.5 Change pulse monitoring time [Err].
Should the measuring device fail during filling and no more pulses be generated, the
valve would no longer close.
A pulse monitoring time [Err] can be set to prevent this. If no pulses can be registered
during the set time period, the Err output is actuated, the symbol "Err" flashes on the
display and outputs [S1] and [S2] are switched off (the valves are closed).
5.6 Use external Start/Stop [Ext].
Filling can also be done via a pushbutton (closer) via an external Start/Stop input with-
out the electronic analysis unit being accessed.
5.7 Use Filling OK [OK] signal.
A pulse is generated at the OK output following a successful filling process.
A further counter could be started using this output via the external Start/Stop. The
output could also be used to operate an additional cycle counter.
5.8 Set Auto correction time [AC].
When the valves are actuated, it still takes a certain time until the valves are closed.
During this time, a certain number of pulses can still be generated by the measuring
unit that are not registered. To ensure that these pulses can be analysed, the unit must
continue counting after the valve has been closed until there are no more pulses. This
waiting time is known as the "Auto Correction" time [AC].
The electronic analysis unit then shuts off the valves earlier by the volume measured
here so that the volume of liquid that would otherwise have been filled in too much is
automatically corrected.
