Predetermining counters (or preset counters) are essentially totalizers
that can switch an external circuit when its counted total matches a
user-entered preset limit. They can be used in manufacturing and
process applications to control batch lot size, cutting material to length,
punching or drilling, and many other count, position, or length related
operations.
Our brand names, VEEDER-ROOT and DYNAPAR, are recognized
worldwide for innovative designs, quality, durability, and accuracy – and
are backed by over 120 years experience in development and
application of counting and controlling instruments. This expertise has
led to a product range that spans all counting technologies –
mechanical, electric, and electronic.
Electronic predetermining counters bring the advantages of modern
digital displays, high counting speeds, multiple presets, silent operation,
and long life. Our general purpose types are comparably priced to other
technologies and are very easy to install and use. An important,
powerful feature provided by electronic designs is the automatic reset
function. The counter is instantly recycled when its output occurs –
permitting control of repetitive operations without human intervention.
The electronic predetermining counter’s high speed and compatibility
with a variety of sensors makes them ideal for length-cutting,
positioning, or liquid/gas flow applications that demand precise,
repeatable control.
For your most challenging applications, consider our state-of-the-art
programmable counters. They offer maximum flexibility through user
selected advanced features such as: input calibrators, movable decimal
point, bidirectional counting modes, and output logic options.
In some applications they may actually replace two or more individual
counters – providing cost effective, customized solutions to your
counting and controlling problems.
DISPLAY TYPES
Liquid Crystal Displays (LCD) are best suited for installation in areas
where there is reasonably good lighting and are superior to most other
display types when viewed in very bright ambient light; such as direct
sunlight. They may be difficult to view in very dimly lit areas, but some
counters overcome this problem through use of an internal light source.
Light Emitting Diode (LED) displays, since they produce their own light,
can be viewed in very dimly lit areas – even in the dark. Their high
contrast presentation makes them the preferred type when the display
must be observed from a distance. Our Series C628 "AWESOME"
products feature display color change at alarm presets.

SPECIFYING A PREDETERMINING COUNTER
Basic considerations when selecting a predetermining counter for your
application are:
Additional selection criteria for predetermining counters include:
Input – What is to be counted and from where will the counter’s input
be obtained?
Count Speed – Speed ratings vary. Check Specifications.
Number of Digits – Based on Maximum Count Value
Type and Size of Display – Should accommodate operating
environment’s viewing and lighting conditions
Packaging – Mounting requirements and Enclosure Size
Environmental – Temperature Specification
Number of Preset Limits:Electronic preset counters are available
with one, two, or more preset limits. Each preset limit can detect a
specific count value and actuate its own independent output.
Although simple single limit types will suffice for many applications,
there are times when additional preset limits can greatly enhance the
operation of a machine or process. For example, a two limit electronic
counter can be used for cutting material to a length controlled by its
first preset, while a second preset is used as a “prewarn” that reduces
the machine’s speed prior to making the cut – permitting increased
accuracy.
Output Device: Most predetermining counters include internal
contacts that can switch a wide voltage range of AC or DC circuits
that draw moderate power. The relay is capable of directly controlling
solenoids, valves, shears, lights, buzzers, etc.
Some electronic types provide a transistor output. These are capable
of switching low power DC loads only. They are ideal for direct
connection to solid-state devices such as programmable logic
controllers. Transistor output devices provide the advantages of
reliability and fast switching speed.
Output Action: Many electronic predetermining counters incorporate
user selectable output action features. Our simplest types provide
choice of a fixed duration momentary output or latched output. Our
programmable models have additional flexibility allowing custom
setting of momentary output times, as well as logic functions that can
enhance the counter’s contribution to the overall application.
