OptiView™ control center
The OptiView™ control center is factory-mounted, wired and tested. The electronic panel
automatically controls the operation of the unit in meeting system cooling requirements while
minimizing energy usage. For detailed information on the control center, see
.
Solid state starter (optional)
The solid state starter is a reduced voltage starter that controls and maintains a constant current
flow to the motor during start-up. It is mounted on the chiller. Power and control wiring between
the starter and chiller are factory installed. The starter enclosure is NEMA-1 with a hinged access
door with lock and key. Electrical lugs for incoming power wiring are provided.
Variable speed drive (optional)
A variable speed drive can be factory packaged with the chiller. It is designed to vary the
compressor motor speed and pre-rotation vane position by controlling the frequency and voltage
of the electrical power to the motor. Operational information is contained in
Form 160.00-O1
,
Form
160.00-O4
, and
Form 160.00-O10
, depending on the model of drive used on the chiller. The control
logic automatically adjusts motor speed and compressor pre-rotation vane position for maximum
part load efficiency by analyzing information fed to it by sensors located throughout the chiller.
