General informationWarrantyTrainingWarranty is based on the generalterms and conditions of themanufacturer. The warranty is voidif the equipment is repaired ormodified without the writtenapproval of the manufacturer, if theoperating limits are exceeded or ifthe control system or the electricalwiring is modified. Damage due tomisuse, lack of maintenance orfailure to comply with themanufacturer's instructions orrecommendations is not covered bythe warranty obligation. If the userdoes not conform to the rules ofthis manual, it may entailcancellation of warranty andliabilities by the manufacturer.To assist you in obtaining the bestuse of it and maintaining it inperfect operating condition over along period of time, themanufacturer has at your disposal arefrigeration and air conditioningservice school. The principal aim ofthis is to give operators andtechnicians a better knowledge ofthe equipment they are using, orthat is under their charge. Emphasisis particularly given to theimportance of periodic checks onthe unit operating parameters aswell as on preventive maintenance,which reduces the cost of owningthe unit by avoiding serious andcostly breakdown.Maintenance contractIt is strongly recommended that yousign a maintenance contract withyour local Service Agency. Thiscontract provides regularmaintenance of your installation bya specialist in our equipment.Regular maintenance ensures thatany malfunction is detected andcorrected in good time andminimizes the possibility thatserious damage will occur. Finally,regular maintenance ensures themaximum operating life of yourequipment. We would remind youthat failure to respect theseinstallation and maintenanceinstructions may result inimmediate cancellation of thewarranty.RLC-SVU05A-E43

OverviewThe Trane CH530 control systemthat runs the chiller consists ofseveral elements: The main processor collectsdata, status, and diagnosticinformation and communicatescommands to the LLID (for LowLevel Intelligent Device) bus. Themain processor has an integraldisplay (DynaView). LLID bus. The main processorcommunicates to each input andoutput device (e.g. temperatureand pressure sensors, lowvoltage binary inputs, analoginput/output) all connected to afour-wire bus, rather than theconventional control architectureof signal wires for each device. The communication interface toa building automation system(BAS). A service tool to provide allservice/maintenance capabilities.Main processor and service tool(TechView) software isdownloadable fromwww.Trane.com. The process isdiscussed later in this sectionunder TechView Interface.DynaView provides busmanagement. It has the task ofrestarting the link, or filling in forwhat it sees as "missing" deviceswhen normal communicationshas been degraded. Use ofTechView may be required.The CH530 uses the IPC3 protocolbased on RS485 signal technologyand communicating at 19.2 Kbaudto allow 3 rounds of data persecond on a 64-device network.Most diagnostics are handled by theDynaView. If a temperature orpressure is reported out of range bya LLID, the DynaView processes thisinformation and calls out thediagnostic. The individual LLIDs arenot responsible for any diagnosticfunctions.Note: It is imperative that the CH530Service Tool (TechView) be used tofacilitate the replacement of anyLLID or reconfigure any chillercomponent.Controls InterfaceDynaView (picture on cover)Each chiller is equipped with theDynaView interface. DynaView hasthe capability to display additionalinformation to the advancedoperator including the ability toadjust settings. Multiple screens areavailable and text is presented inmultiple languages as factoryordered or can be easilydownloaded online.TechViewTechView can be connected to theDynaView module and providesfurther data, adjustmentcapabilities, diagnosticsinformation, downloadablesoftware, and downloadablelanguages.RLC-SVU05A-E45

DynaView InterfacePower UpOn power-up, Dynaview willprogress through 3 screens.The first screen (Figure 1) willdisplay for 3-10 seconds. Thisscreen will give the status of theApplication software, the BootSoftware P/N, selftest results andthe application part number. Thecontrast is adjustable from thisscreen. The message "Selftestpassed" may be replaced with "Err2:RAM Error" or "Err3: CRC Failure"Note that the Application and Bootsoftware numbers will varyaccording to the unit type.If no application is found, the screen(Figure 2) will display instead ofFigure 1.Figure 1Figure 26RLC-SVU05A-E4

DynaView InterfaceThe second screen (Figure 3) willdisplay for 15-25 seconds. If a validconfiguration is present, "TracerCH530" will also be displayed. If theMP configuration is found to beinvalid, "MP: Invalid Configuration"is displayed indefinitely. Contactyour local Trane service technician.The third screen is the first screenof the application.Figure 3Figure 4RLC-SVU05A-E47

DynaView InterfaceThe display on DynaView is a1/4 VGA display with a resistivetouch screen and an LED backlight.The display area is approximately4 inches wide by 3 inches high(102mm x 60mm).CAUTION!Equipment Damage! Puttingexcessive pressure on the touchscreen could cause damage. It takesless than 7 kg of force to break thescreen.In this touch screen application, keyfunctions are determinedcompletely by software and changedepending upon the subject mattercurrently being displayed. The basictouch screen functions are outlinedbelow.Radio ButtonsRadio buttons show 1 menu choiceamong 2 or more alternatives, allvisible. The possible selections areeach associated with a button. Theselected button is darkened,presented in reverse video toindicate it is the selected choice.The full range of possible choicesas well as the current choice isalways in view.Spin Value ButtonsSpin values are used to allow avariable setpoint to be changed,such as leaving water setpoint. Thevalue increases or decreases bytouching the ( ) or (-) arrows.Action ButtonsAction buttons appear temporarilyand provide the user with a choicesuch as Enter or Cancel.File Folder TabsFile folder tabs are used to select ascreen of data. The tabs are in1 row across the top of the display.The user selects a screen ofinformation by touching theappropriate tab.Figure 5 - Basic Screen FormatDisplay ScreensThe main body of the screen is usedfor description text, data, setpoints,or keys (touch sensitive areas). TheChiller Mode is displayed here.A double arrow pointing to the rightindicates more information isavailable about the specific item onthat same line. Pressing it will bringyou to a sub-screen that willpresent the information or allowchanges to settings.98RLC-SVU05A-E4

DynaView InterfaceThe bottom of the screen (7) ispresent in all screens and containsthe following functions. Thecontrast (8,9) may require readjustment at ambienttemperatures significantly differentfrom those present at lastadjustment. The other functions arecritical to machine operation. TheAUTO and STOP keys are used toenable or disable the chiller. Thekey selected is in black (reversevideo). The chiller will stop whenthe STOP key is touched and aftercompleting the Run Unload mode.Touching the AUTO key will enablethe chiller if no diagnostic ispresent. (A separate action must betaken to clear active diagnostics.)The AUTO and STOP keys takeprecedence over the Enter andCancel keys. (While a setting isbeing changed, AUTO and STOPkeys are recognized even if Enter orCancel has not been pressed.) TheALARMS button appears only whenan alarm is present, and blinks (byalternating between normal andreverse video) to draw attention toa diagnostic condition. Pressing theALARMS button takes you to thecorresponding tab for additionalinformation.Note: screens may differ accordingto unit type or configuration. Theyshould be considered as examples.Keypad/Display LockoutFeatureNote: The DynaView display andTouch Screen Lock screen is shownabove. This screen is used if theDisplay and touch screen and lockfeature is enabled. Thirty minutesafter the last keystroke, this screenis displayed and the Display andTouch Screen is locked out until thesequence "159 ENTER " ispressed. Until the proper passwordis entered, there will be no accessto the DynaView screens includingall reports, setpoints, andAuto/Stop/Alarms/Interlocks. Thepassword "159" can not be changedfrom either DynaView or TechView.For setting changes, use thepassword "314 ENTER ".System/Circuit Selection ButtonsOn some report and setting screens,radio buttons on the top of thescreen shall be presented to allowthe user to select subscreens basedon system-level data and per-circuitdata.Figure 6 - Keypad1RLC-SVU05A-E4For single-circuit units withsystem/circuit selection buttons, thebuttons shall be labeled (in English)“System” and “Ckt”. For two-circuitunits with system/circuit selectionbuttons, the buttons shall belabeled “System”, “Ckt1”, and“Ckt2”.9
