MENU 12.BATCH
Menu visualized only with batch active (output on batch and/or pos. 5.9 enable or 5.10
on batch)
(POS. 12.1) Number of batch samples [N.SAMPLES=XXX]
Number of batch cycles to be done to define the value of compensation. This function allows to
automatically determine the average value for automatic compensation of system delay (POS. 9.3) .
Set to ZERO this function for manually introduction of the compensation value.
(POS. 12.2) % limit of compensation [DIFF.THR=%XXX]
This value defines the percentage of maximum difference between the compensation value set (see
pos. 12.3) and the average compensation value defined with the function 12.1. Over this threshold
the new compensation value will be automatically set (if Number of batch samples is different from
zero)
(POS. 12.3) Compensation value
[V.COM.=XX.XXX]
This value, expressed in the same selected volume unit of measure, is the result of the difference
between the batch value set and the quantity of product really supplied due to the system delays:
closing valves, stop pumps, stop motors, etc. Attention: if you need to set manually the value of
compensation, preset to ZERO the Number of batch samples (POS. 12.1)
(POS. 12.4) Prebatch value
[V.PRE.=XX.XXX]
set the volume of liquid at which you want to enable the pre-batch. When the pre-batch volume “V
Pre” is reached the output (if enabled) is de-activated. This value is constant for all quantities to be
batched and must be set in current volume unit of measure. The pre-batch function is useful when
you need fast and accurate fillings.
(POS. 12.5) Enable/disable auto-batch function [AUTO BATCH=ON/OFF]
Applying a voltage on the on/off input terminals for more than 5 second the valve controlled by the
meter stands open while the voltage is applied on the input. When the product has reached the
desired volume/level, removing the voltage from the input, the meter closes the valve and memorizes
the supplied product volume in the current memory batch (see "BATCH FUNTIONS"); the value
obtained with this procedure will be the volume supplied in every following batch. In order to modify
this value, repeat the operations above. This procedure set the safety timer at a value 1.25 times
greater than the time used to reach the batched quantity; after that the counter will be reset.
(POS. 12.6) Automatic selection of batch formula [BM AUTO SEL=ON/OFF]
The function allows the automatic selection of the first 4 formulas depending on the duration of the
pulse of the batch start (see page 11 "Input operation stage"). This function is active only if the
function cons. mode (POS. 12.7) has not enabled. Besides, activating this function, the automatic
compensation of the batch volume is also excluded (the value of the parameter "N.medie" (POS.
12.1) will be automatically set to zero). However the manual compensation is possible introducing the
opportune value on the parameter "V.com" (POS. 12.3)
(POS. 12.7) Static consent of batch [Cons. mode=ON/OFF]
The function enable the start and the stop of the dosing using a static signal, instead of an impulsive,
applied to the input (see pag. 11 "Digital input), this signal will have to stand applied all through the
batch. This function automatically disables the functions "BM AUTO SEL" (POS. 12.6) and " AUTO
BATCH" (POS. 12.5).
