FEATURES
7.1 - Batching feature
The PRO–CTR has a
Batching
function, which is used to maintain the total count,
as well as the current
Batch Value
. The
Batch Value
is calculated using the following
formula:
Batch Value = Primary Count – Batch Tare
The
Batch Tare
value is reset to the
Primary Count
value via the setpoint reset func-
tion
RST BT
, which can be executed by setpoint logic (see 9.2M) or manually by
activating an appropriately confi gured user input pin (see 3.6 & 8.5). (
Batch Tare
is a
hidden register used only for this calculation.)
The controller also includes a
Batch Counter
function associated with
SP 1
. The 'Batch
Count Modifi er' value (see 9.2P) is added to the
Batch Count
register each time
SP 1
activates, allowing the user to count how many completed batches have been
processed.
