Function description<br />
SPECIAL FUNCTION BATCHING FUNCTION VALVE PARAMETER<br />
The parameters for the switching contacts <strong>of</strong> up to 2 valves can be set in the following functions.<br />
The number <strong>of</strong> switching contacts (valves) available, and thus their settings in this group, is defined in the function<br />
BATCH STAGES (7208).<br />
! Note!<br />
The following functions are only available if at least one batch stage has been selected in the function BATCH<br />
SELECTOR (7200).<br />
OPEN VALVE 1<br />
(7220)<br />
Use this function to specify the quantity value at which contact 1 opens. This is used as a<br />
switch point for valve 1 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 1<br />
(7221)<br />
Use this function to display the quantity value at which contact 1 (valve 1) closes. The<br />
quantity value is displayed either as a % or as an absolute value, depending on the option<br />
in the function INPUT FORMAT (7209).<br />
Display:<br />
Value or 100% (corresponds to the batching quantity)<br />
Factory setting:<br />
0 [unit] or 0 [%]<br />
! Note!<br />
The switching contact for valve 1 is the “main contact”, i.e. the closing function <strong>of</strong> valve<br />
1 is firmly assigned to the batching quantity entered, (see function BATCH QUANTITY<br />
(7203) onpage 148). In this way, function CLOSE VALVE 1 is also the basis for<br />
calculating the after run quantity.<br />
