13 CTV -PRC0 0 1 -GB Jobsite Connections Supply and Motor Lead Wiring and Connections Copper conductors only should be connected to the compressor motor due to the possibility of galvanic corrosion as a result of moisture if aluminum conductors are used.
CTV -PRC0 01 -GB 14 Controls Standard Features Field Connection The field-connected elements are involved in physically turning the chiller on or off. This involves ensuring that the chiller is not in an emergency or external stop condition, starting the pumps, and verifying that flow has been established.
15 CTV -PRC0 0 1 -GB Extended Operation Package Select the extended-operation package for chillers that require external , hot water control, and/or base-loading capabilities. This package also includes a 4-20 mA or 0-10 Vdc analog input for a refrigerant monitor .
CTV -PRC0 01 -GB 16 Controls Standard Protections T r acer ™ Chiller Contr oller The chiller controller uses proportional- integral-derivative (PID) control for all limits—there is no dead band. This removes oscillation above and below setpoints and extends the capabilities of the c hiller .
17 CTV -PRC0 0 1 -GB Controls Standard Protections Momentary Power Loss and Distribution Fault Protection Three-phase momentary power loss (MPL) detection gives the chiller improved performance through many different power anomalies. MPLs of 2.5 cycles or longer will be detected and cause the unit to shut down.
