SECTION 2 - PRODUCT DESCRIPTION
ACCESSORIES AND OPTIONS
POWER OPTIONS:
COMPRESSOR POWER CONNECTION – Single-
point (YCAL0012-0032) terminal block connection is
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
– (standard on YCAL0012 - 0032 models) Includes
enclosure, terminal-block and interconnecting wiring to
the compressors. Separate external protection must be
supplied, by others, in the incoming compressor-power
wiring. (Do not include this option if either the Single
Point Non Fused Disconnect Switch or Single-Point
Circuit Breaker options 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 compliance 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
includes 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
Condenser 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 INTER-
FACE – 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 Automation System. (Only one of following
options can be offered on a unit at a time: BAS, Remote
Control Panel or Multi-unit Sequence Control) ( Fac-
tory-Mounted ). (The standard unit capabilities include
remote START/STOP, 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 – Span-
ish, French, and German unit LCD controls and keypad
displays are available. Standard language is English.
DISCHARGE PRESSURE TRANSDUCERS AND
READOUT CAPABILITY – The addition of pressure
transducers allows models to sense and display discharge
pressure. This is recommended for brine chilling appli-
cations. (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.
MOTOR CURRENT MODULE – Capable of moni-
toring compressor motor current. Provides extra protec-
tion against compressor reverse rotation, phase-loss and
phase imbalance. Option consists of one module per
electrical system ( Factory-Mounted ).
OPTIVIEW REMOTE CONTROL PANEL - Graphi-
cal 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 Sequenc-
ing 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 ).
