OPEN VALVE 2
MODBUS register:
Data type:
Access:
7222
See Note
Float
read/write
For specifying 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 batching 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 the batching quantity of 10 kg =
7 kg). If the BATCH QUANTITY(7203) is adjusted (reduced/increased), the
effective quantity switch point is automatically and dynamically adjusted (e.g.
at 70% and a new batching quantity changing from 10 to 20 kg, the quantity
switch point is adjusted from 7 kg to 14 kg).
• 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 kg for a
batching quantity of 10 kg). If the BATCH 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.
! Note for MODBUS!
The MOBBUS register depends on the option selected in the function BATCH
SELECTOR (7200):
• BATCH # 1 = MODBUS register 8015
• BATCH # 2 = MODBUS register 8017
• BATCH # 3 = MODBUS register 8019
• BATCH # 4 = MODBUS register 8021
• BATCH # 5 = MODBUS register 8023
• BATCH # 6 = MODBUS register 8025
