LED Digital Indicator and Bargraph Controller 264-DT Series

INSTALLATION INSTRUCTIONSPage 1 of 3Ref: IW264DT – Rev 4 – Sept 02IntroductionThe 264-DT range offers a 101/LED-Bargraph displaywith the added benefit of 4 or 3½ digit display. Thiscombination allows for both accurate instantaneousmeasurement and trend indication.InstallationThe units should be mounted in a reasonably stableambient temperature within the range 0 to 60°C. Theunit should not be mounted where it will be subjected toexcessive sunlight; vibration should be kept to aminimum. Connection wires should be sized to complywith local regulations and should preferably be fitted withtags for the terminals provided. Labels are fixed to theunit and carry connection information, and data includinginput voltage, input current, supply and applications asappropriate. These products do not have internal fusestherefore external fuses must be used for safetyprotection under fault conditions.Typical ApplicationsThe ease of on site programming allows for the use of264-DT series in a wide variety of applications such asProcess Control, Water Treatments, Power Generation,Control Panels and Switchgear Monitoring Systems.Assembly of Partswindows for heat radiation top and bottom(Clearance of 15cm maintained above and below)Acrylic cover Scale plateData LabelNote:264-DTV does not have set points and therefore doesnot have HH, LL, H and L LED’s.264-DTT only has low and high setpoints, therefore,does not have HH and LL LED’s.Functions1. SCALINGSpan and zero on the digital display can be adjustede.g. offset zero. Span and zero on the Bargraphdisplay cannot be adjusted.2. OVER SCALE DISPLAYThe over-range annunciator “Hi” will display andblink on the digital display when the input signalexceeds the span value. The under-rangeDigital IndicatorsLED Digital Indicator &Bargraph Controller 264 DT Seriesannunciator “Lo” will display and blink on the digitaldisplay when the input is below the zero value.3. SETPOINT PROGRAMMINGThe setpoints programming can be changed to suitthe desired positions (Hi/Lo or HiHi/LoLo) any valuebetween zero and span can be selected. If aninvalid value is entered, the processor will select thesetpoint position “OFF”. The setpoints must beprogrammed as HiHi > Hi and Hi > Lo and Lo>LoLo.4. ALARM OUTPUT DELAY FOR EACHSETPOINTThe alarm delay time can be programmed between0 and 10 seconds at 1 second intervals.5. RELAY HYSTERESISThe Hysteresis is to 1% of total scale, and notprogrammable.For programming instructions see overleaf.Fusing and connections1. This unit must be fitted with external fuses involtage and auxiliary supply lines.2. Voltage input lines must be fused with a quick blowfuse 1A maximum.3. Auxiliary supply lines must be fused with a slowblow fuse rated 1A maximum.4. Choose fuses of a type and with a breakingcapacity appropriate to the supply and inaccordance with local regulations.5. Where fitted, CT secondaries must be grounded inaccordance with local regulations.Warning• During normal operation, voltages hazardous to lifemay be present at some of the terminals of this unit.Installation and servicing should be performed onlyby qualified, properly trained personnel' abiding bylocal regulations. Ensure all supplies are deenergisedbefore attempting connection or otherprocedures.• Terminals should not be user accessible afterinstallation and external installation provisions mustbe sufficient to prevent hazards under faultconditions.• Never open circuit the secondary winding of anenergised current transformer.Screw torqueMain terminal screws should be tightened to 1.35Nm or1.0 ft/lbf only. Detachable terminal connector screwsshould be tightened to 0.9Nm or 0.7 ft/lbf only. Wherefitted, terminal covers are held in place by miniature selftapping screws into plastic. These screws should betightened by hand only, sufficiently to secure the terminalcover and prevent it vibrating.Electromagnetic CompatibilityThis unit has been designed to provide protection againstEM (electro-magnetic) interference in line withrequirements of EU and other regulations. Precautionsnecessary to provide proper operation of this andadjacent equipment will be installation dependent and sothe following can only be general guidance:-

In some cases, a supplyline filter may be required.• To protect the product against incorrect operation orpermanent damage, surge transients must becontrolled. It is good EMC practice to suppressdifferential surges to 2kV or less at the source. Theunit has been designed to automatically recoverfrom typical transients, however in extremecircumstances it may be necessary to temporarilydisconnect the auxiliary supply for a period ofgreater than 5 seconds to restore correct operation.• Screened communication and small signal leads arerecommended and may be required. These andother connecting leads may require the fitting of RFsuppression components, such as ferrite absorbers,line filters etc., if RF fields cause problems.It is good practice to install sensitive electronicinstruments that are performing critical functions in EMCenclosures that protect against electrical interferencecausing a disturbance in function.Programming InstructionsAll types of 264-DT have the same operating controlbuttons:-M = Mode S = Store▲ = Up ▼ = DownThe annunciator LED’s on the right hand display are asfollows and flash when that particular parameter is beingprogrammed.Z = Zero LEDP = Decimal point LEDS = Span LEDL = Low relay LED ) 264-DTT )H = High relay LED ) )HH = High High relay LED ) 264-DTFLL = Low Low relay LED )Programming 264-DT1.
