Veeder Root V454502 Dual Preset Counter Technical Manual

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).
