OptiView Control Center

OPTIVIEw CONTROL CENTER

The YORK OptiView Control Center, furnished as standard

on each chiller, provides the ultimate in efficiency, 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 or R-22 screw chillers. The panel is configured

with a 10.4 inch diagonal color Liquid Crystal Display

(LCD) surrounded by “soft” keys, which are redefined with

one keystroke based on the screen display at that time.

This revolutionary development 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. All date representations and calculations

use four digits for the year to provide Year 2000 compli-

ance.

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 specific 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

field interlocks that indicate the chiller status. These con

tacts include a Remote Mode Ready To Start, a Cycling
