" Caution!
• When the batching quantity is adjusted (reduced/increased), (see function
BATCH QUANTITY (7203) on Page 132) there is no automatic adjustment, i.e.
this value must be determined again and reentered, (see also fault message
# 472 in the Operating Instructions BA107D).
• Batching (START) is not possible when the fault message is active!
• The function is not active if you enter 0 (factory setting).
• A fault message is assigned to the function.
This fault message can be acknowledged prematurely:
– By modifying a batching function.
– By selecting RESET in the “BATCH PROCEDURE” parameter
• This function can be output via the switch output.
! Note for MODBUS!
Depends on the option selected in the function BATCH SELECTOR (7200):
• BATCH # 1 = MODBUS register 8075
• BATCH # 2 = MODBUS register 8077
• BATCH # 3 = MODBUS register 8079
• BATCH # 4 = MODBUS register 8081
• BATCH # 5 = MODBUS register 8083
• BATCH # 6 = MODBUS register 8085

read/write
For specifying a maximum batching quantity. If the maximum batching quantity is
exceeded during batching, all valves are closed, batching is stopped and a message
is generated. The quantity value is entered as a % or as an absolute value,
depending on the option in the function INPUT FORMAT (7209).
Application: To avoid overbatching and thus prevent critical situations caused by
fluid overflow arising in the plant, (e.g. plant standstill caused by safety level
switches being triggered, contamination, product loss, etc.).
User input: 0 to 2 x max. value or 0 to 200% (related to the batching quantity)
Factory setting: 0 [unit] (= deactivated)
