BATCHING EXECUTION
The batching consists of an initial FAST phase and a subsequent SLOW phase.
During the entire batching execution, the instrument:
-
monitors the weight of the product’s batched quantity;
-
commands the PRESET and SET contacts according to the
parameter setting (see section
OPERATION SETTINGS
);
-
if the
time is set and the product is not loaded by at least 20 divisions within this interval
of time, activates the
alarm.
The FAST phase ends when one of the following conditions occurs:
-
only if
is set: the batched quantity has reached the set value minus the slow value;
-
the batched quantity has reached the preset value set in formula.
During the SLOW phase:
-
only if
is set: the instrument does not verify the reaching of set value until the
NO
COMPARISON TIME
has elapsed;
-
if a tapping value has been set, the SET contact performs opening and closing cycles according
to the times set by
and
parameters.
When the batched quantity reaches the set value configured in the formula minus any fall value, the
SLOW phase ends and the SET contact opens, interrupting the product flow.
WAITING PHASE
After opening the SET, the instrument waits for:
-
only if
=
: the waiting time has elapsed (
);
-
only if
=
: the START input has been closed or the command 209 has been sent to
CMDR;
-
only if
=
: the weight is stable.
If the tolerance (
) is set, three conditions can occur:
-
the batched quantity is less than the set quantity minus the tolerance value; the SLOW phase is
performed again to improve the batching accuracy. If the error condition persists, the
alarm
is activated;
-
the batched quantity is greater than the set quantity plus the tolerance value; the
alarm is
enabled;
-
the batched quantity falls within the tolerance limits.
To cancel the
alarm and proceed, send command 207 to CMDR.
When all the set conditions are met, the waiting phase ends and the batching cycle continues.
