MENU 12.BATCH
Menu visualized if with batch feature active
(output on batch and/or pos. 5.9 enabled 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 measuring unit, 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]
To 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 measuring unit. 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]
Apply a voltage on the on/off input terminals for more than 5 seconds the valve controlled by the
transmitter 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 transmitter 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 12 "Input operation stage"). This function is active only if the function
cons. mode (POS. 12.7) is not enabled. Besides, activating this function, the automatic compensation
of the batch volume is also excluded (the value of the parameter "N.samples" (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 enables the start and the stop of the dosing using a static signal, instead of pulse signal,
applied to the input (see pag. 12 "Digital input), this signal must be applied all through the batch. This
function automatically disables the functions "BM AUTO SEL" (POS. 12.6) and " AUTO BATCH" (POS.
12.5).
