CL-1 to CL-14INTRODUCTIONPrior to initial start-up of the 19XR unit, those involved inthe start-up, operation, and maintenance should be thoroughlyfamiliar with these instructions and other necessary job data.This book is outlined to familiarize those involved in the start-up, operation and maintenance of the unit with the control sys-tem before performing start-up procedures. Procedures in thismanual are arranged in the sequence required for proper chillerstart-up and operation.ABBREVIATIONS AND EXPLANATIONSFrequently used abbreviations in this manual include:Words printed in all capital letters or in italics may beviewed on the International Chiller Visual Controller (ICVC)(e.g., LOCAL, CCN, ALARM, etc.).Words printed in both all capital letters and italics can alsobe viewed on the ICVC and are parameters (e.g., CONTROLMODE, COMPRESSOR START RELAY, ICE BUILDOPTION, etc.) with associated values (e.g., modes, tempera-tures, percentages, pressures, on, off, etc.).Words printed in all capital letters and in a box representsoftkeys on the ICVC control panel (e.g., , ,, , etc.).Factory-installed additional components are referred to asoptions in this manual; factory-supplied but field-installed ad-ditional components are referred to as accessories.The chiller software part number of the 19XR unit is locatedon the back of the ICVC.CHILLER FAMILIARIZATION (FIG. 1-3)Chiller Information Nameplate — The informationnameplate is located on the right side of the chiller controlpanel.System Components — The components include thecooler and condenser heat exchangers in separate vessels,motor-compressor, lubrication package, control panel, econo-mizer (optional) and motor starter. All connections from pres-sure vessels have external threads to enable each component tobe pressure tested with a threaded pipe cap during factory as-sembly.CAUTIONThis unit uses a microprocessor control system. Do notshort or jumper between terminations on circuit boards ormodules; control or board failure may result.Be aware of electrostatic discharge (static electricity) whenhandling or making contact with circuit boards or moduleconnections. Always touch a chassis (grounded) part to dis-sipate body electrostatic charge before working inside con-trol center.Use extreme care when handling tools near boards andwhen connecting or disconnecting terminal plugs. Circuitboards can easily be damaged. Always hold boards by theedges and avoid touching components and connections.This equipment uses, and can radiate, radio frequencyenergy. If not installed and used in accordance with theinstruction manual, it may cause interference to radio com-munications. It has been tested and found to comply withthe limits for a Class A computing device pursuant to Inter-national Standard in North America EN 61000-2/3 whichare designed to provide reasonable protection against suchinterference when operated in a commercial environment.Operation of this equipment in a residential area is likely tocause interference, in which case the user, at his ownexpense, will be required to take whatever measures maybe required to correct the interference.Always store and transport replacement or defective boardsin anti-static shipping bag.CAUTIONDo NOT punch holes or drill into the top surface of theVFD (variable frequency drive) enclosure for field wiring.Knockouts are provided on the side of the VFD enclosurefor field wiring connections. The top panel of the enclosuremust be removable for servicing the power module.CAUTIONPROVIDE MACHINE PROTECTION. Store machineand starter indoors, protected from construction dirt andmoisture. Inspect under shipping tarps, bags or crates to besure water has not collected during transit. Keep protectiveshipping covers in place until machine is ready forinstallation.CAUTIONWHEN FLUSHING THE WATER SYSTEMS isolate thechiller from the water circuits to prevent damage to the heatexchanger tubes.CCM — Chiller Control ModuleCCN — Carrier Comfort Network ®CCW — CounterclockwiseCW — ClockwiseECDW — Entering Condenser WaterECW — Entering Chilled WaterEMS — Energy Management SystemHGBP — Hot Gas BypassI/O — Input/OutputICVC — International Chiller Visual ControllerISM — Integrated Starter ModuleLCD — Liquid Crystal DisplayLCDW — Leaving Condenser WaterLCW — Leaving Chilled WaterLED — Light-Emitting DiodeOLTA — Overload Trip AmpsPIC II — Product Integrated Controls IIRLA — Rated Load AmpsSCR — Silicon Controlled RectifierSI — International System of UnitsTXV — Thermostatic Expansion ValveVFD — Variable Frequency DriveENTER EXITINCREASE QUIT
