V454501 Single Preset Counter - Danaher Specialty Products

IntroductionA new standard of performance and functionality in a compact presetcounter. The V454501 Single Preset Counter offers a pre-settablecounter with full calibration for a variety of applications.The bright red LED display provides simultaneous count and presetindication. The use of annunciators and simple key sequences makesoperator changes quick and easy. A variety of count sources areaccommodated, including relay and pushbutton contacts, photocellsand proximity switches and uni- or bi-directional incremental encoders.The open collector output can interface to light duty devices and therelay contacts offer heavy duty load switching.Set-up and installation are simplifiedthroughfront panel entry of configurationparametersand a unique “no tools required” panelmounting bracket.The V454500 family of preset counterscombines state-of-the-art circuitry andelectronic assembly techniques with anergonomic package design that resultsin the most cost-effective ,high-performance counter valueon the market.Features*Dual four-digit displays for Countand Preset values*10kHz count speed*Add/Subtract or bi-directionalcount inputs*Digital calibrator andprogrammable decimal point*Accepts current sinking orsourcing devices*Key reset, remote reset and autoreset modes*Reset to zero or preset number*Relay (SPDT) and open collectoroutputs*Accessory sensor power supply*Universal 90 - 264V AC powerrequirements*NEMA 4/IP65 sealed front panel*Designed to comply withEN50081 and EN50082 EMCspecificationsIndexOverviewConstruction Page 2InstallationWiring Page 3Panel Mounting Page 4OperationFront Panel Page 5ProgrammingViewing Preset Value Page 6Changing Preset Value Page 6Program Mode Page 7Configuration Mode Page 8Appendix A - Specifications Page 9Order Codes Page 12

Connect the shield only to thebuilding earth (ground).AC Power InputConnect AC power to Terminal 7 (Line) via a 1Aslow-blow fuse and to Terminal 8 (Neutral) - see below.AC power should be from a separate branch circuitwhich is noise-free and does not feed heavy loads.Current Sourcing (PNP) Count InputsConnect Add count input to Terminal 2 (A) and/or Subtractcount input to Terminal 3 (B) - see below. In ConfigurationMode, set PuLL parameter to no and, for Add/Subtractoperation, set InPu parameter to A-B.PNP Open CollectorDC/Low Voltage AC Power InputConnect DC/low voltage AC power to Terminal 7 (+)via a 0.5A slow-blow fuse and to Terminal 8 (–) - seebelow. DC power should have low ripple and benoise-free.Contact ClosureReset and Program InputsConnect Reset pushbutton or current sink device to Reset(Terminal 5) and COM (Terminal 4).

Do not route load wiring nearcount input or transistor output signals.Open Collector OutputConnect Terminals 12 (open collector) and 4 (COM) to solid statedevices as shown below (upper circuit). To drive DC relay coils,connect Terminal 12 and V+ (Terminal 1) as shown on below (lowercircuit).

The maximumpanel thickness is 6 mm.45m45mSingleInstallatio(48n - 4)mmMultiple Installation (nCounters)CAUTIONDo not remove the panelgasket from the Counter asthis may result ininadequate clamping of theCounter in the mountingpanel.Insert the rear of the Counter housingthrough the cut-out (from the front of themounting panel) and hold the Counterlightly in position against the panel. Ensurethat the panel gasket is not distorted and thatthe Controller is positioned squarely againstthe mounting panel. Apply pressure to thefront panel bezel only. Slide the mountingbracket in place (see right) and push itforward until it is firmly in contact with therear face of the mounting panel (tongues onthe bracket should engage in matchingrachet positions on the Counter housing andthe mounting bracket springs should pushfirmly against the mounting panel rear face).Rear face of mounting panelMounting bracketCounterhousingTongues on mounting bracketengage in ratchet slots on Counter housing
