SECTION 1 - SYSTEM FUNDAMENTALS

The graphic display can display data in either English

or Metric mode.

• English (temperatures in °F and pressures in

PSIA)

• Metric (temperatures in °C and pressures in kPa)

The control center continually monitors system opera-

tions. Operators are advised of chiller conditions by

use of various status and warning messages. This data

is recorded and preserved in memory even through a

power failure. Operational data, warnings and shut-

down messages may be viewed at any time.
In addition, the control center may use alarms to no-

tify the user of certain conditions. A complete listing of

shutdown, status, and warning messages is listed in the

Display Messages on page 90

of this manual.

The control center includes capabilities for remote con-

trol and communications. Common networking proto-

col through the Building Automation System (BAS) al-

lows increased remote control of the chiller, as well as

24-hour performance monitoring via a remote site. An

optional circuit board called the SC-EQUIP provides

Johnson Controls and YORK mechanical equipment

such as the YZ chiller with building automation system

(BAS) networking connectivity.
The chiller also maintains standard digital remote ca-

pabilities. Both of these remote control capabilities al-

low for the following standard Energy Management

System (EMS) interfaces. The actual connection de-

tails are in the Field Connections section of the

Wiring

Diagram (Form 161.01-PW1 and PW3)

•  Remote Start
•  Remote Stop
•  Remote Leaving Chilled Liquid Temperature

Setpoint adjustment: BAS coms, Analog signal,

(0-10VDC or 4-20mA) or Pulse Width Modula-

tion

• Remote Current Limit Setpoint adjustment: BAS

coms, Analog signal, (0-10VDC or 4-20mA) or

Pulse Width Modulation

•  Remote “Ready to Start” Contacts
•  Safety Shutdown Contacts
•  Cycling Shutdown Contacts

The OptiView panel can be used to control the cus-

tomer chilled and condenser liquid flow. A set of con-

tacts exists to initiate flow for each shell. Details are in

the Field Connections section of the

Wiring Diagram

(Form 161.01-PW2 and PW4)

. The chilled water pump

contacts close immediately upon execution of a chiller

start command. They open coincident with the receipt

of a stop command or a fault other than those below:

A. LEAVING CHILLED LIQUID - LOW TEM-

PERATURE cycling shutdown.

B. MULTIUNIT CYCLING - CONTACTS OPEN

or SYSTEM CYCLING - CONTACTS OPEN

(Only if Chilled Liquid Pump Operation is set to

ENHANCED)

C. LEAVING CHILLED LIQUID FLOW SWITCH

OPEN cycling shutdown

The Condenser Pump contacts close immediately upon

execution of a chiller start command. They open coin-

cident with receipt of a chiller stop command or fault

other than CONDENSER-FLOW SWITCH OPEN cy-

cling shutdown.
If the chiller is stopped and the condenser pump con-

tacts are open (flow off), the contacts close when satu-

rated condenser temperature is less than 35.0 °F (1.67

°C). This helps mitigate condenser freeze due to plant

issues in brine applications.
If the contacts are closed only due to the saturated con-

denser temperature, they are opened when saturated

condenser temperature returns above 40.0 °F (4.44

°C). If the existing logic calls for them to be closed,

they remain closed.
Some screens, displayed values, programmable

setpoints and manual controls exist for service techni-

cian use only. They are only displayed when logged in

at SERVICE access level or higher. These parameters

affect chiller operation and should never be modified

by anyone other than a qualified service technician.
The chiller operating program resides in the Opti-

View Control Center microboard. Software versions

(Y.OPT.01.xx.yzz) are alpha-numeric codes that rep-

resent the application, language package and revision

levels as follows.
