4-3 Controller Operation (Standard Controller)
Using the Standard Touchscreen Interface
Introduction
The Standard touchscreen interface lets you control your Screw Compressor central chilling
station. You can do such things as:
x
Control compressors and optional pumps
x
View current statuses of operation, such as pressures, temperatures,
and capacities
x
Handle alarm conditions
This section lists special instructions for operating the standard touchscreen interface.
Note:
The screens shown in this section are
sample
screens. Actual screen
representations may be slightly different in appearance, but are no different
in operation.
On all screens in this controller, the
F4
button is reserved for the previous screen function.
Some screens, such as the chiller status screen, do not have sufficient space to display a
prompt that the
F4
performs this function. However, the
F4
button will always move to the
previous screen and will eventually return to the Main Menu.
The Standard touchscreen interface is the “manager” of your central chilling station. The
screen contains screen buttons you can press to control system operation.
For example
, if you need to resolve an alarm condition, press the
or
buttons on
the right side of the screen to highlight “
ACTIVE ALARM LIST
”. The screen will tell you
what alarm is active and you may clear the alarm by touching the
F1
button located to the
lower left of the terminal.
To return to the Main Menu screen at this point, press the
F4
button of the terminal, located
in the lower right corner. The Main Menu screen then displays.
Some screens let you directly control the operation of the chilling station, while others are for
information purposes and are “display-only” screens. This section distinguishes between
operation and display screens.
