Installation - Electrical Power Supply Wiring All power supply wiring must be sized and selected accordingly by the project engineer in accordance with NECTable 310-16. WARNING Proper Field Wiring and Grounding Required! All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards.
PAGE 107
Installation - Electrical Control Power Supply The unit is equipped with a control power transformer; it is not necessary to provide additional control power voltage to the unit. All units are factory-connected for appropriate labeled voltages. Interconnecting Wiring Chilled Water Flow (Pump) Interlock If paddle option is selected, RTWD/RTUD Series R® chillers require a field-supplied control voltage contact input through a flow proving switch 5S5 and an auxiliary contact 5K9 AUX.
PAGE 108
Installation - Electrical Alarm and Status Relay Outputs (Programmable Relays) A programmable relay concept provides for enunciation of certain events or states of the chiller, selected from a list of likely needs, while only using four physical output relays, as shown in the field wiring diagram.The four relays are provided (generally with a Quad Relay Output LLID) as part of the Alarm Relay Output Option.The relay’s contacts are Table 91.
PAGE 109
Installation - Electrical Emergency Stop CH530 provides auxiliary control for a customer specified/ installed latching trip out. When this customer-furnished remote contact 5K24 is provided, the chiller will run normally when the contact is closed. When the contact opens, the unit will trip on a manually resettable diagnostic.This condition requires manual reset at the chiller switch on the front of the control panel. Connect low voltage leads to terminal strip locations on 1A5, J2-3 and 4.
PAGE 110
Installation - Electrical External Chilled or Hot Water Setpoint (ECWS/EHWS) Option The CH530 provides inputs that accept either 4-20 mA or 210 VDC signals to set the external water setpoint (EWS). • When the unit is in cooling mode, the EWS will correspond to the chilled water setpoint (ECWS). • When the unit is in heating mode, the EWS will correspond to the hot water setpoint (EHWS). This is not a reset function.The input defines the set point.
PAGE 111
Installation - Electrical Depending on the type to be used, theTechView Service Tool must be used to configure the LLID and the MP for the proper input type that is being used.This is accomplished by a setting change on the CustomTab of the Configuration View withinTechView. Outdoor The J2-3 and J2-6 terminal is chassis grounded and terminal J2-1 and J2-4 can be used to source 12 VDC.The ECLS uses terminals J2-2 and J2-3. ECWS uses terminals J2-5 and J2-6.
PAGE 112
Installation - Electrical Outdoor Air Temperature Sensor Installation Requirements The outdoor air temperature sensor is optional for the RTWD water cooled units, but is a required sensor for the RTUD compressor chiller units.The sensor is required as an important input to the condenser fan control algorithm as well as for the low outdoor air ambient lockout feature. The temperature sensor probe is shipped separately inside the control panel.
PAGE 113
Installation - Electrical shielded, twisted pair connection establishes the bidirectional communications link between theTracer CH530 and the building automation system. Note: To prevent control malfunctions, do not run low voltage wiring (<30 V) in conduit with conductors carrying more than 30 volts. WARNING Proper Field Wiring and Grounding Required! All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards.

A metered amount of refrigerant liquid enters a distribution system in the evaporator shell and is then distributed to the tubes in the evaporator tube bundle.The refrigerant absorbs heat and vaporizes as it cools the water flowing through the evaporator tubes. Refrigerant vapor leaves the evaporator as saturated vapor (State Pt. 1).

RTWD/RTUD Operating Principles Oil System Operation (RTWD/RTUD) Overview Oil that collects in the bottom of the oil separator is at condensing pressure during compressor operation; therefore, oil is constantly moving to lower pressure areas. As the oil leaves the separator, it passes through the oil cooler (if installed). It then goes through the service valve and filter. At this point it travels through the oil control valve.Then it provides oil injection and bearing lubrication.
PAGE 130
RTWD/RTUD Operating Principles The helical rotary compressor is a positive displacement device.The refrigerant from the evaporator is drawn into the suction opening at the end of the motor barrel, through a suction strainer screen, across the motor, and into the intake of the compressor rotor section.The gas is then compressed and discharged directly into the discharge line. There is no physical contact between rotors and compressor housing.
