The KEP BATCHtrol-II batch controller may be thought of as two separate counters and
a ratemeter. The "batching" counter counts to pre-warn and preset numbers entered by
the user and enables separate control outputs. The "totalizing" counter gives a
cumulative reading or grand total. Finally, the ratemeter counts the number of pulses
per second and, with its scaling feature, can provide gallons per minute or any other
rate measurement without the totalizer losing counts. At any time, the user may view
the total, the grand total or the rate while never interrupting the counting process.
Featuring a bright, 8-digit alphanumeric display, the KEP BATCHtrol-II
batch controller can accept up to 20,000 pulses per second of digital count. The analog
input version accepts 4 to 20 mA or 1 to 5V. The standard unit has two
separate, 8-digit, floating decimal, "K" factors to convert the inputs to meaningful
total and rate data. An optional 16-point K-factor can linearize flow from nonlinear
meter outputs. The user, with the push of a button, can toggle back and forth to view
the total of the batch, the rate of flow or the grand total of flow.
Setup of the BATCHtrol-II is done through the front panel and the menu driven software in the unit. The start-stop
control can be activated via the front panel buttons or remote inputs. This KEP unit operates
from either 110 VAC/12 to 27 VDC, or optional 220 VAC/12 to 27 VDC. If AC power is used, two
built-in regulated 12 VDC @ 100 mA power supplies are offered. They can be connected to
provide 12 VDC and -12VDC or 24 VDC to drive external devices. CMOS Logic is used to provide
high noise immunity and low power consumption with EEPROM to hold data a minimum of 10 years
if power is interrupted. Up to 15 addresses can be defined for the optional RS232 or RS422
communications port and units multi-dropped. The serial port can be used to set control points
or access data.
