Introduction
A new standard of performance and functionality in a compact preset
counter. The V454502 Dual Preset Counter offers a pre-settable
counter with full calibration for a variety of applications.
The bright red LED display provides simultaneous count and preset
indication. The use of annunciators and simple key sequences makes
operator changes quick and easy. A variety of count sources are
accommodated, including relay and pushbutton contacts, photocells
and proximity switches and uni- or bi-directional incremental encoders.
The open collector output can interface to light duty devices and the
relay contacts offer heavy duty load switching.
Set-up and installation are simplified
through
front panel entry of configuration
parameters
and a unique “no tools required” panel
mounting bracket.
The V454500 family of preset counters
combines state-of-the-art circuitry and
electronic assembly techniques with an
ergonomic package design that results
in the most cost-effective ,
high-performance counter value
on the market.

IMPORTANT: In severe electrical noise environments, shielded cable is
recommended for inputs and outputs. Connect the shield only to the
building earth (ground).
AC Power Input
Connect AC power to Terminal 7 (Line) via a 1A
slow-blow fuse and to Terminal 8 (Neutral) - see below.
AC power should be from a separate branch circuit
which is noise-free and does not feed heavy loads.
DC/Low Voltage AC Power Input
Connect DC/low voltage AC power to Terminal 7 (+)
via a 0.5A slow-blow fuse and to Terminal 8 (–) - see
below. DC power should have low ripple and be
noise-free.
Reset and Program Inputs
Current Sourcing (PNP) Count Inputs
Connect Add count input to Terminal 2 (A) and/or Subtract
count input to Terminal 3 (B) - see below. In Configuration
Mode, set PuLL parameter to no and, for Add/Subtract
operation, set InPu parameter to A-B .
PNP Open Collector
Contact Closure
Current Source or
Line Driver
Connect Reset pushbutton or current sink device to Reset
(Terminal 5) and COM (Terminal 4). Connect Program
switch or jumper to PGM (Terminal 6) and COM
(Terminal 4).
Bi-directional Quadrature Inputs
Connect Quadrature Encoder to V+ (Terminal 1), A input
(Terminal 2), B input (Terminal 3) and COM (Terminal 4) as
shown below. In Configuration Mode, set InPu parameter to
QuAd . For NPN open collector devices with no pullup
resistors, set PuLL parameter to YES .
Current Sinking (NPN) Count Inputs
Connect Add count input to Terminal 2 (A) and/or Subtract
count input to Terminal 3 (B) - see below. In Configuration
Mode, set PuLL parameter to YES and, for Add/Subtract
operation, set InPu parameter to A-B .

Panel Mounting
Make cut-out(s) according to the details in
the diagram on the right. The maximum
panel thickness is 6 mm.
Insert the rear of the Counter housing
through the cut-out (from the front of the
mounting panel) and hold the Counter
lightly in position against the panel. Ensure
that the panel gasket is not distorted and that
the Controller is positioned squarely against
the mounting panel. Apply pressure to the
front panel bezel only. Slide the mounting
bracket in place (see right) and push it
forward until it is firmly in contact with the
rear face of the mounting panel (tongues on
the bracket should engage in matching
rachet positions on the Counter housing and
the mounting bracket springs should push
firmly against the mounting panel rear face).
