Operating the Microprocessor

The touchscreen interface panel is ready to use when it is
connected to the Ethernet switch and chiller power is on.
Upon initial startup, the status line will indicate that the
chiller is off. Press and hold the ON/OFF button for few
seconds on the touchscreen interface panel turns the
chiller on and the status line will indicate that it is powered
on the LCD screen of the Client module. Press and hold this
button effectively toggles the chiller ON and OFF.

Microprocessor Functions

For practical purposes, all essential control information
and operator actions are read and responded to using the
touchscreen interface panel. The touchscreen interface
panel is connected to the client microprocessor controller
and is the only way to access many client controller
functions.
NOTICE
Component Damage!
Failure to follow instructions could damage sensitive
electronic components beyond repair. To prevent arcing
or surges of electrical current, do not use wires or
cables to jump components or bypass the
manufacturer's safety systems.

Password Protection

There are three levels of access to the functions displayed
on the interface. The basic level, 'user,' does not require a
password. The higher access levels are the technician
('tech') and administrator ('admin') levels that can only be
accessed by Trane technical personnel. Contact Trane
technical support regarding the possibility of any potential
issues involving the higher-level functions.

Operator Control

A touchscreen interface panel is the primary means for the
operator or maintainer to monitor and modify a host of
functions involving temperatures, pressures, set points,
alarms, operating schedules, and elapsed operating
hours. This touchscreen interface panel is located inside
the control panel.
The touchscreen interface is connected to and
communicates with all module controllers via the Ethernet
switch. It accesses overall chiller/heater functions and
settings as well as individual module settings.
In this manual, all functions, procedures, checklists,
system information, and changes in system parameters
(set points, alarms, client chiller controls, and so forth) are
written assuming the operator is using the touchscreen
interface panel.
When connected to the Ethernet switch, the touchscreen
interface panel displays current, real-time, information
about the chiller, as well as the status of critical parameters
within each module of the chiller.

Touchscreen Interface Panel

The touchscreen interface panel is used to adjust set
points, clear alarms, and perform detailed setup of the
microprocessor controllers.
The touchscreen interface panel displays information on
its touchscreen whenever specific keys and buttons are
pressed by the operator (See below figure.)
Basic operator tasks are described in the following
sequence of illustrations that comprise a controller
tutorial.
