Discharge Pressure Transducers And Readout Capability; Accessories And Options - York YCAL0019 Installation, Operation And Maintenance Manual

SECTION 2 – PRODUCT DESCRIPTION
Power Options
Compressor Power Connection
Single-point (YCAL0019-0066) terminal block con-
nection is provided as standard. The following power
connections are available as options. (See electrical
data for specific voltage and options availability) (Fac-
tory-Mounted).
Single-Point Supply Terminal Block
(Standard on YCAL0019 – 0066 models)
Includes enclosure, terminal-block and interconnect-
ing wiring to the compressors. Separate external pro-
tection 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 in-
cluded).
Single-Point Non-Fused Disconnect Switch
Unit-mounted disconnect switch with external, lock-
able handle (in compliance with Article 440-14 of
N.E.C.), can be supplied to isolate the unit power volt-
age 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). Factory mounting includes primary
and secondary wiring between the transformer and the
control panel (Factory-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
22

ACCESSORIES AND OPTIONS

Discharge Pressure Transducer / Readout Capability
option. For proper head pressure control in applica-
tions below 25 °F (-4 °C), where wind gusts may ex-
ceed 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 tem-
perature is above 110 °F (43 °C). Includes discharge
pressure transducers. This option includes the Dis-
charge Pressure Transducer / Readout Capability op-
tion (Field-Mounted).
Building Automation System Interface
The factory addition of a Printed Circuit Board to ac-
cept a 4 to 20 milliamp, 0 to 10VDC or contact closure
input to reset the leaving chiller liquid temperature
from a Building Automation System. Only one of fol-
lowing options can be offered on a unit at a time:
• BAS
• Remote Control Panel
• Multi-unit Sequence Control (Factory-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
Spanish, 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 recom-
mended for brine chilling applications. This option is
included with either the low or high ambient kits (Fac-
tory-Mounted).
