4-4 Controller Operation (Advanced Controller)
Using the Advanced Touchscreen Interface
Introduction
The Advanced touchscreen interfaces let 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 advanced touchscreen interfaces.
Note:
The screens shown in this chapter are
sample
screens. Actual screen
representations may be slightly different in appearance, but are no
different in operation. Also, the PLC is configured based on options
and system configuration at the time of order. These screens are the
basic ones to startup the chiller.
The Advanced touchscreen interface is the “manager” of your screw compressor central
chilling station. This screen contains screen buttons you can press to control system
operation.
For example
, if you need to resolve an alarm condition, press the Up or Down arrow buttons
on the right side of the screen to highlight “
ACTIVE ALARMS
”. Press
and the screen
will display all active alarms.
To return to the Main Menu screen at this point, press the
Menu
button on the screen, 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.
