Function description
SPECIAL FUNCTION BATCHING FUNCTION SUPERVISION
MAX. BATCHING
QUANTITY
(7242)
Use this function to specify 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...2 x max. value or 0...200% (related to the batching quantity)
Factory setting:
0 [unit] (= deactivated)
" Caution!
• When the batching quantity is adjusted (reduced/increased), (see function BATCH
QUANTITY (7203) on page 148), there is no automatic adjustment, i.e. this value
must be determined again and reentered (see also the fault message # 472 in the
Operating Instructions Proline Promass 83, BA 059D/06/en, Troubleshooting
Chapter).
• Batching (START) is not possible when the fault message is active!
! Note!
• The function is not active if you enter 0 (factory setting).
• As a factory setting, this function is assigned a fault message. This appears for
60 seconds. The fault message can be acknowledged earlier by changing a batching
function.
• If this function is intended more for general monitoring purposes or if there is a short
time lapse between two batching processes, it is advisable to assign this function to a
notice message, (see function ERROR CATEGORY on page 181). However, while the
notice message is active (60 seconds) the next batching can be started and the notice
message is acknowledged.
• This function can be output via the switch output.
PROGRESS NOTE
(7243)
Use this function to define a batching quantity at which a message should be generated.
When the specified batching quantity is achieved, the message is generated and signaled
via the output.
The quantity value is entered as a % or as an absolute value, depending on the option in
the function INPUT FORMAT (7209).
Application:
For longer batching processes when preparing or taking measures related to production
(e.g. preparing to replace container, etc.).
User input:
0 to max. value or 0 to 100% (related to the batch quantity)
Factory setting:
0 [unit] (= deactivated)
" Caution!
When the batching quantity is adjusted (reduced/increased), (see function BATCH
QUANTITY (7203) on page 148), there is no automatic adjustment, i.e. this value must
be determined again and reentered, (see also notice message # 473 in the Operating
Instructions Proline Promass 83, BA 059D/06/en, Troubleshooting Chapter).
! Note!
• The function is not active if you enter 0 (factory setting).
• This function can be output via the switch output.
• The batching progress message remains active until batching ends.
