Accessories and Options

CONTROL CIRCUIT TERMINAL STRIP – Provides power input terminals for field provided power input

in lieu of factory mounted control circuit transformer. 115V, 1Control Circuit Power Terminal Strip lo- cated in the Microprocessor Panel to accept a field provided control power circuit with appropriate branch circuit protection in accordance with appli- cable Local and National codes. Provides unit con- trol circuit power, including supply to the 24V, fused Microprocessor panel transformer.

BUILDING AUTOMATION SYSTEM (BAS) INTER- FACE – Provides means to reset the leaving chilled liquid temperature or percent full load amps (cur- rent limiting) from the BAS (Factory Mounted):

Printed circuit board to accept 4 to 20 milliamp, 0 to 10 VDC, or dry contact closure input from the BAS.

A YORK ISN Building Automation System can pro- vide a Pulse Width Modulated (PWM) signal di- rect to the standard control panel via the standard on-board RS485 port.

PRIMARY CHILLER POWER CONNECTIONS – See Electrical Data on pages 78 through 89 for spe- cific voltage and options availability. Separate ex- ternal branch circuit protection and disconnecting means must be supplied by others in accordance with applicable Local and National codes. (Factory Mounted)

âMultiple Point Supply – Standard field power wiring connection on all models is Multiple Point Power Connection to factory provided Terminal Blocks. Two field supplied electrical power circuits with appropriate branch circuit protection provide power to each of two motor control center cabi- nets, located adjacent to each other at one end of the chiller. Each cabinet contains starter elements for one or two compressors and their associated fan motor starters.

Optional to the Terminal Blocks for field power connection are Non-Fused Disconnects with ex- ternal lockable handles, or (on two compressor machines only) Circuit Breakers with external lock- able handles. Also Optional (on 3 & 4 compres- sor machines equipped with multiple point power supply) are individual system circuit breakers per each compressor with external lockable handles.

ãSingle-Point Supply – Optional to the Multiple Point power connection configurations are Single- Point Supply arrangements. A wide variety of these single-pointOptions are offered to satisfy most any customer connection requirement:

Single-Point with Individual System Breakers

These options consist of field connection to ei- ther a unit mounted Terminal Block, or a Non-

Fused Disconnect Switch with external, lockable handle (in compliance with Article 440-14 of N.E.C., to isolate unit power supply for service). Factory wiring is provided from the Terminal Block or Disconnect Switch to factory supplied Individual System Circuit Breakers with external, lockable handles in each of the two compressor motor con- trol centers.

Single-Point Supply – Also optional (on two com- pressor machines only) are Single-Point Supply configurations for field connection of a single elec- trical circuit to: Terminal Block, Non-Fused Dis- connect Switch with lockable external handle (in compliance with Article 440-14 of N.E.C., to iso- late unit power supply for service), or Circuit Breaker with lockable external handle. Factory wiring is provided from the Terminal Block, Dis- connect Switch, or Breaker directly to the starter components in each of the two compressor motor control centers.

STAR (WYE)-DELTA COMPRESSOR MOTOR STARTER – Provides smooth starting and approxi- mately 65% reduced inrush current compared to across-the-line type start. Two compressor units equipped with any of the Single-Point Power con- nection options and Star-Delta starters must also be equipped with Individual System Circuit Break- ers option. Three and four compressor units with Star-Delta starters must also include Individual Sys- tem Circuit Breakers option. (Factory Mounted) See Electrical Data (pages 79 - 89) for availability and coordination with individual system short circuit pro- tection.

CONDENSER COIL PROTECTION – Standard con- denser coil construction materials include aluminum fins, copper tubes, and galvanized tube supports for generally good corrosion resistance. However, these materials are not adequate for all environments. The system designer can take steps to inhibit coil corro- sion in harsh applications and enhance equipment life by choosing from these options based on project design parameters and related environmental fac- tors. For additional application recommendations refer to Form 150.12-ES1. (Factory Mounted)

Black Fin Condenser Coils – Condenser coils constructed using black epoxy coated aluminum fin stock for corrosion resistance comparable to copper fin coils in typical seashore locations. Ei- ther this or phenolic (below) recommended for units installed in coastal environments.

Phenolic Coated Condenser Coils – Completed condenser coil assemblies are covered with a cured phenolic coating. Probably the best choice for seashore or where salt spray may hit the fins,
