SECTION 2 – SYSTEM ARCHITECTURE
The following LCSSS components are located in an
enclosure mounted to the compressor motor terminal
box. (Refer to
Figure 4 on page 15
and
Figure 5 on
page 16 .)
• SCR Assemblies
• Current Transformers
• Logic/Trigger Board
• Control Circuit Fuses
• Oil Pump Motor Fuses
• Circuit Breaker or Disconnect Switch if used.
A control power transformer is attached to the side of
the starter enclosure. This supplies 115 VAC control
power to the starter and OptiView Control Center. The
YK chiller uses a transformer which is different from
that used on YT and YS chillers.
