DESCRIPTION
Batching
The Aro MiniĆBatcher opens a valve when the ``start" button is pressed,
allowing fluid to flow through a measuring device. The unit reads the
pulses fromthemeasuring deviceand closesthe valvewhen thepredeĆ
termined amount of fluid has passed.
Prewarn
Relay ``B" may be used for a prewarn signal to indicate when the endof
the batch is approaching. Relay ``A" may control a low flow valve and
relay ``B" a high flow valve to dispense fluid rapidly until a certain point
where the high flow valve closes and allows the batch to finish slowly,
assuring accuracy.
Ratemeter and Totalizer
At any time during the batching process, the transfer rate of the fluid,
the total amount of fluid dispensed or the total numberof batches delivĆ
ered may be viewed. The rate may be displayed in units per hour, minĆ
ute or second. The totalizer may be reset at any time using the ``reset /
stop" key.
Lock
The program for the MiniĆBatcher may be locked by code in two differĆ
ent modes. ``LOCK PROG" mode allows only the preset value to be
changed during operation, while the ``start" and ``stop" buttons function
normally. The ``LOCK ALL" mode does not allow any changes to the
program to be made, though the preset value may be viewed and the
``start" and ``stop" buttons function normally.
Counting
Pulses to the MiniĆBatcher for recording the amount of fluid dispensed
may be generated several ways. If a commercial flowmeter is used, it
must have a pulse outputand the``highcycles" setting mustbe used on
the meter. An Aro diaphragm or piston pump with a cycle counter may
also be used with the meter on the ``low cycles" setting. Discharge volĆ
umes per cycle for various Aro pumps can be found later in this docuĆ
ment. Any type of proximity switch may also be used to generate the
pulsed output required by the unit.
Power Requirements
The standard MiniĆBatcher may be powered by either 110 VAC or 12 -
15 VDC for maximum installation flexibility. Other voltages are also
available.
