OptiView Control Center

OPTIVIEW CONTROL CENTER

The YORK OptiView Control Center, furnished as standard

on each chiller, provides the ultimate in efciency, monitor-

ing, data recording, chiller protection and operating ease.

The control center is a factory mounted, wired, and tested

state-of-the-art microprocessor based control system

for R-134a screw chillers. The panel is congured with

a 10.4 inch diagonal color Liquid Crystal Display (LCD)

surrounded by “soft” keys, which are redened with one

keystroke based on the screen display at that time. The

display is rated at 450 nits. This revolutionary develop-

ment makes chiller operation quicker and easier than ever

before. Instead of requiring keystroke after keystroke to

hunt for information on a small monochrome LCD screen,

a single button reveals a wide array of information on a

large, full-color illustration of the appropriate component,

which makes information easier to interpret. This is all

mounted in the middle of a keypad interface and installed

in a locked enclosure.

The LCD display allows graphic animated display of the

chiller, chiller sub-systems and system parameters; this

allows the presentation of several operating parameters

at once. In addition, the operator may view a graphical

representation of the historical operation of the chiller as

well as the present operation. A Status Bar is displayed

at all times on all screens. It contains the System - Status

Line and Details Line, the Control Source, Access Level,

Date and Time.

During the Start Sequence and System Lockout Delay, the

system status will include a countdown timer indicating the

time remaining. The control panel is compatible with the

YORK Solid State Starter (optional), Electro-mechanical

(E-M) starter, or any customer supplied E-M starter that

complies with the YORK R-1051 standard. The locations

of various chiller parameters are clearly marked and in-

structions for specic operations are provided. The panel

verbiage is available in other languages as an option, with

English always available. Data can be displayed in either

English or Metric units, plus keypad entry setpoints of 0.1

increments.

Security access is provided to prevent unauthorized ac-

cess and/or a change of setpoints. This is accomplished

with three different levels of access and passwords for

each level. There are screens, displayed values, program-

mable setpoints and manual controls not shown available

to service the chiller. They are only displayed when logged

in at the service access level. The Advanced Diagnostics

and troubleshooting information for the chiller and the

panel is also included.

The panel is fused through a 1-1/2 or 2 KVA transformer

in the compressor motor starter to provide individual

over-current protected power for all controls. Numbered

terminal strips for wiring such as Remote Start/Stop,

Flow Switch, Chilled Water Pump and Local or Remote

Cycling Device are provided. The Panel also provides

eld interlocks that indicate the chiller status. These

contacts include a Remote Mode Ready To Start, a Cy-

cling Shutdown, a Safety Shutdown and a chiller Run

Contact. Pressure transducers sense system pressures

and thermistors sense system temperatures. The output

of each transducer is a DC voltage that is analogous to

the pressure input. The output of each thermistor is a DC

voltage that is analogous to the temperature it is sensing.
