SOLID STATE STARTER
The Solid State Starter is a reduced voltage starter that
controls and maintains a constant current flow to the
motor during startup. It is compact and mounted on the
chiller at the motor terminals. Power and control wiring
is factory supplied. Available for 200-600 volts, the
starter enclosure is NEMA-1 with a hinged access door
with lock and key. Electrical lugs for incoming power
wiring are provided.
Standard features include: digital readout at the OptiV-
iew Control Center of the following:
Display Only:
• 3-phase voltage A, B, C
• 3-phase current A, B, C
• Input power (kW)
• kW Hours
• Starter Model
• Motor Run (LED)
• Motor Current % Full-load Amps
• Current Limit Setpoints
• Pulldown Demand Time Left
Programmable:
• Local Motor Current Limit
• Pulldown Demand Limit
• Pulldown Demand Time
Other features include: low line voltage; 115-volt con-
trol transformer; three-leg sensing overloads; phase ro-
tation and single-phase failure protection; high tempera-
ture safety protection; motor current imbalance and
undervoltage safeties; open and close SCR protection;
momentary power interruption protection. The LCSSS
is cooled by a closed-loop, fresh water circuit consist-
ing of a water-to-water heat exchanger and 1/25 HP
circulating pump. All interconnecting water piping is
factory installed and rated for 150 PSIG working pres-
sure. Optional unit-mounted circuit breaker includes
ground fault protection and provides 65,000 amp short-
circuit withstand rating in accordance with UL Standard
508. A non-fused disconnect switch is also available.
Both options are padlockable.
BAS REMOTE CONTROL
A communication interface permitting complete ex-
change of chiller data with any BAS system is available
with optional ISN translator. ISN translator also allows
BAS system to issue commands to the chiller to control
its operation. ISN translators come in two models, con-
trolling up to four chillers and eight chillers respectively.
FACTORY INSULATION OF EVAPORATOR
Factory-applied thermal insulation of the flexible, closed-
cell plastic type, 3/4" (19mm) thick is attached with va-
por-proof cement to the evaporator shell, flow cham-
ber, evaporator tube sheets, suction connection, and
(as necessary) to the auxiliary tubing. Not included is
the insulation of water boxes and nozzles. This insula-
tion will normally prevent condensation in environments
with relative humidities up to 75% and dry bulb tem-
peratures ranging from 50° to 90°F (10° to 32°C). 1-1/
2" (38mm) thick insulation is also available for relative
humidities up to 90% and dry bulb temperatures rang-
ing from 50° to 90°F (10° to 32°C).
WATER FLANGES
Four 150 Ib. ANSI raised-face flanges, for condenser
and evaporator water connections, are factory welded
to water nozzles. Companion flanges, bolts, nuts and
gaskets are not included.
SPRING ISOLATION MOUNTING
Spring Isolation mounting is available instead of stan-
dard isolation mounting pads when desired. Four level-
adjusting/spring-type vibration isolator assemblies with
non-skid pads are provided with mounting brackets for
field installation. Isolators are designed for one-inch
(25.4 mm) deflection.
WATER FLOW SWITCHES
Paddle-type, vapor-proof water flow switches suitable
for 150 psig (1034 kPa) DWP for chilled and condenser
water circuits. Switch for 115V-1-50/60 Hz service. A
chilled water flow switch is required. Condenser water
flow switch is optional.
SEQUENCE CONTROL KIT
For two, three or four units with chilled water circuits
connected in series or parallel, the kit consists of return
water thermostat, lead-lag selector switch for sequence
starting, and time delay relay, with NEMA-1 enclosures,
designed for 115V-1-50/60 Hz.
STARTER – FIELD INSTALLED
A field installed, electro-mechanical compressor motor
starter is available, selected for proper size and type
for job requirements and in accordance with YORK En-
gineering Standard R-1131 for Starters.
