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