SPECIAL FUNCTION BATCHING FUNCTION VALVE PARAMETER<br />
OPEN VALVE 2<br />
(7222)<br />
Use this function to specify the quantity value at which contact 2 opens. This is used as a<br />
switch point for valve 2 to output via an assigned output. The quantity value is entered as<br />
a % or as an absolute value, depending on the option in the function INPUT FORMAT<br />
(7209).<br />
User input:<br />
0 to max. value or 0 to 100% (related to the batch quantity)<br />
Factory setting:<br />
0 [unit] or 0 [%]<br />
! Note!<br />
• Dynamic tracking for %-data:<br />
If the value is entered as a %, this %-value always refers to the batching quantity<br />
(e.g. 70% <strong>of</strong> a batching quantity <strong>of</strong> 10 liters = 7 liters).<br />
If the BATCH QUANTITY (7203) is adjusted (reduced/increased), the effective<br />
quantity switch point is automatically and dynamically adjusted (e.g. taking 70% and<br />
changing the batching quantity from 10 to 20 liters, the quantity switch point is<br />
adjusted from 7 liters to 14 liters).<br />
• Dynamic tracking for value-data:<br />
If you enter value-input, this value is “absolute” for batching quantities that do not<br />
change (e.g. always 7 liters for a batching quantity <strong>of</strong> 10 liters). If the batching quantity<br />
(7203) is adjusted (reduced/increased), the quantity switch point is automatically and<br />
dynamically adjusted/tracked (e.g. with a new batching quantity changing from 10 to<br />
20 liters, the quantity switch point is adjusted from 7 liters to 14 liters). In other<br />
words, the existing value data is tracked as a percentage <strong>of</strong> the altered batching<br />
quantity.<br />
CLOSE VALVE 2<br />
(7223)<br />
Use this function to specify the quantity value at which contact 2 closes. This is used as a<br />
switch point for valve 2 to output via an assigned output. The quantity value is entered as<br />
a % or as an absolute value, depending on the option in the function INPUT FORMAT<br />
(7209).<br />
User input:<br />
0 to max. value or 0 to 100% (related to the batch quantity)<br />
Factory setting:<br />
0 [unit] or 0 [%]<br />
