CL-I to CL-12INTRODUCTIONPrior to initial start-up of the 19XRV unit, those involved inthe stall-up, operation, and maintenance should be thoroughlyfamiliar with these instructions and other necessary job data.This book is outlined to fmnili;uize those involved in thestmt-up, operation and maintenance of the unit with the controlsystem before performing stmt-up procedures. Procedures inthis manual ;ue arranged in the sequence required for properchiller start-up and operation.This unit uses a microprocessor control system. Do notshol_t or jumper between terminations on circuit bo;uds 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 todissipate body electrostatic charge before working insidecontrol centel:Use extreme c;ue when handling tools near bo;uds andwhen connecting or disconnecting terminal plugs. Circuitboards can easily be &_maged. 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 accor&mce with theinstruction manu;fl, it may cause interference to radiocommunications. It has been tested and found to complywith the limits for a Class A computing device pursuant toSubpart J of Pall 15 of FCC Rules, which are designed toprovide reasonable protection against such interferencewhen operated in a commercial environment. Operation ofthis equipment in a residential area is likely to causeinterference, in which case the usel: at his own expense,will be required to take whatever measures may berequired to correct the interference.Always store and transport replacement or defective boardsin anti-static shipping bag.ABBREVIATIONS AND EXPLANATIONSFrequently used abbreviations in this manual include:CCM -- Chiller Control ModuleCCNCCWCWECDWECWEMSHGBPI/OICVCLCDLCDWLCWLEDOLTAPIC IIIRLASCRSlTXVVFD-- Carrier Comfort Network-- Counterclockwise-- Clockwise-- Entering Condenser Water-- Entering Chilled Water-- Energy Management System-- Het Gas Bypass-- Input/Output-- International Chiller Visual Controller-- Liquid Crystal Display-- Leaving Condenser Water-- Leaving Chilled Water-- Light-Emitting Diode-- Overload Trip Amps-- Product Integrated Controls III-- Rated Load Amps-- Silicon Controlled Rectifier-- International System of Units-- Thermostatic Expansion Valve-- Variable Frequency DriveWords printed in all capital lettel_ or in italics may beviewed on the International Chiller Visual Controller (ICVC)(e.g., LOCAL, CCN, ALARM, etc.).W_rds printed in both all capital letters and italics can alsobe viewed on the ICVC and are parmneters (e.g., CONTROLMODE, COMPRESSOR START RELAY, ICE BUILDOPTION, etc.) with associated values (e.g., modes, tempera-tures, percentages, pressures, on, off. etc.).W_rds printed in all capital lettel_ and in a box representsoftkeys on the ICVC control panel (e.g., _, _,[INCREASE[, _, etc.).
