MAXIMUM
BATCHING TIME
MODBUS register:
Data type:
Access:
7240
See Note
Float
read/write
For specifying a maximum batching time. All valves close once the specified
batching time elapses, (see function CLOSE VALVE 1 (7221), Page 138 and
CLOSE VALVE 2 (7223), Page 140).
This function can be used for safety reasons, for example, to ensure all batching
valves close in the event of a system fault.
User input: 0 to 30000 s
Factory setting: 0 s (= deactivated)
" 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 #
471 in the Operating Instructions BA107D).
• Batching (START) is not possible when the fault message is active!
! Note!
• The function is not active if you enter 0 s (factory setting).
This means that the batching valves are not closed by means of this function.
• 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 8063
• BATCH # 2 = MODBUS register 8065
• BATCH # 3 = MODBUS register 8067
• BATCH # 4 = MODBUS register 8069
• BATCH # 5 = MODBUS register 8071
• BATCH # 6 = MODBUS register 8073
MINIMUM
BATCHING
QUANTITY
MODBUS register:
Data type:
Access:
7241
See Note
Float
read/write
For specifying a minimum batching quantity. A message is generated if the
minimum batching quantity was not achieved by the time batching ends (e.g. if
after run mode is active). The quantity value is entered as a % or as an absolute
value, depending on the option in the function INPUT FORMAT (7209).
Application:Message stating that underbatching is present (e.g. the contents of
the containers does not correspond to the quantity declared).
User input: 0 to max. value or 0 to 100% (related to the batching quantity)
Factory setting: 0 [unit] (= deactivated)
