POWER OPTIONS:
COMPRESSOR POWER CONNECTIONS – Single- point (YCAL0041-0065) terminal block connection(s) are provided as standard. The following power connections are available as options. (See electrical data for specific voltage and options availability.) (Factory-Mounted.)
SINGLE-POINT SUPPLY TERMINAL BLOCK – (stan- dard on YCAL0041 - 0065 models). Includes enclosure, terminal-block and interconnecting wiring to the com- pressors. Separate external protection must be supplied, by others, in the incoming compressor-power wiring. (Do not include this option if either the SinglePoint NonFused Disconnect Switch or Single-Point Circuit Breaker op- tions have been included.)
SINGLE-POINT NON-FUSED DISCONNECT SWITCH
–Unit-mounted disconnect switch with external, lockable handle (in compliance with Article 440-14 of N.E.C.), can be supplied to isolate the unit power voltage for servicing. Separate external fusing must be supplied, by others in the power wiring, which must comply with the National Electrical Code and/or local codes.
SINGLE-POINT CIRCUIT BREAKER – A unit mounted circuit breaker with external, lockable handle (in com- pliance with N.E.C. Article 440-14), can be supplied to isolate the power voltage for servicing. (This option includes the Single-Point Power connection.)
CONTROL TRANSFORMER – Converts unit power voltage to 115-1-60 (0.5 or 1.0 KVA capacity). Fac- tory mounting includes primary and secondary wiring between the transformer and the control panel. (Fac- tory-Mounted.)
POWER FACTOR CORRECTION CAPACITORS – Will correct unit compressor power factors to a 0.90-0.95.(Factory-Mounted.)
CONTROL OPTIONS:
AMBIENT KIT (LOW) – Units will operate to 25°F (-4°C). This accessory includes all necessary components to permit chiller operation to 0°F (-18°C). (This option in- cludes the Discharge Pressure Transducer / Readout Capability option.) For proper head pressure control in applications below 25°F (-4°C), where wind gusts may exceed five mph, it is recommended that Optional Con- denser Louvered Enclosure Panels also be included. (Factory-Mounted.)
AMBIENT KIT (HIGH) – Required if units are to operate when the ambient temperature is above 115°F (46°C). Includes discharge pressure transducers. (This option
includes the Discharge Pressure Transducer / Readout- Capability option.) (Field-Mounted.)
BUILDING AUTOMATION SYSTEM INTERFACE – The factory addition of a Printed Circuit Board to accept a 4-20 milliamp, 0-10VDC or contact closure input to reset the leaving chiller liquid temperature from a Building Au- tomation System. (Only one of following options can be offered on a unit at a time: BAS, Remote Control Panel or Multi-unit Sequence Control.) (Factory-Mounted.) (The standard unit capabilities include remote startstop, remote water temperature reset via a PWM input signal or up to two steps of demand (load) limiting depending on model.) (The standard control panel can be directly connected to a YORK Building Automated System via the standard onboard RS485 communication port.)
LANGUAGE LCD AND KEYPAD DISPLAY – Spanish, French, and German unit LCD controls and keypad display available. Standard language is English.
DISCHARGE PRESSURE TRANSDUCERS AND READOUT CAPABILITY – The addition of pressure transducers allows models to sense and display dis- charge pressure. This is recommended for brine chilling applications. (This option is included with either the low or high ambient kits.) (Factory-Mounted.)
•Suction Pressure Transducers: Permits unit to sense and display suction pressure. This capability is standard on YCAL0041-0065 models.
MOTOR CURRENT MODULE – Capable of monitoring compressor motor current. Provides extra protection against compressor reverse rotation, phase-loss and phase imbalance. Option consists of one module per electrical system. (Factory-Mounted.)
OPTIVIEW REMOTE CONTROL PANEL - Graphical interface panel to remotely control and monitor up to 8 different units. (Refer to form 201.18-SG4 for detailed information)
MULTI-UNIT SEQUENCING – A separate Sequencing Control Center is provided to handle sequencing control of up to eight chillers in parallel based on mixed liquid temperature (interconnecting wiring by others). (Only one of following options can be offered on a unit at a time: BAS, Remote Control Panel or Multi-unit Sequence Control.) (Factory-Mounted.)
COMPRESSOR, PIPING, EVAPORATOR OPTIONS:
LOW TEMPERATURE BRINE – Required for brine
