Introduction
The Tracer AdaptiView™ display provides a means for viewing data and for making operational
changes on gear-driven, water-cooled CenTraVac™(CVGF) chillers.
The purpose of this guide is to assist you in using the Tracer AdaptiView display. The guide
describes how to access the screens and the types of information that appear on the screens.

Equipment Description
The basic equipment features of the Tracer AdaptiView display are described here.

Hardware
The Tracer AdaptiView display is mounted on or near the chiller control panel. It can be attached
to the chiller by an arm that can extend 11 inches. Five pivot points enable full articulation as
described in the following specifications and in the illustration:
• Two horizontal pivots points 90º right or left (180º total)
• Two vertical pivots points: 90º degrees up or down (180º total)
• Rotation: 135º clockwise and 135º counterclockwise (270º total)

Screen characteristics
The 12.1-inch VGA touch-sensitive color screen displays data in either inches and pounds (IP) or
standard international (SI) units, and in one of twenty-four available languages. Animated color
graphics indicate the status of the chiller and its components.

CTV-SVU02A-EN 5
Introduction

AC power
The Tracer AdaptiView display receives AC power through its power cable, which is connected to
the Tracer UC800 controller. The Tracer UC800 controller must be powered On.

Communication
A separate cable provides communication between the Tracer AdaptiView display and the Tracer
UC800 controller. Alarms are communicated immediately upon detection.

Touchscreen Guidelines
The touch screen registers the downward pressure of a touch. Light, quick, yet deliberate presses
are most effective. Touching with more pressure has no effect.
Recommended tools to use: finger, thumb, pencil eraser. Do not use a pen or pencil point, or any
other sharp or pointed object that might scratch the screen surface.
If you apply and hold pressure at more than one point, the touch screen registers only the first
touch. For example, if you press a finger on an area of the screen that is not touch sensitive,
pressing a sensitive area with another finger will not register.
Holding on to the screen with your hand can cause unintended navigation, such as from thumb or
palm pressure.

Warning

Viewing Active and Historic Alarms

You can view alarms by three different categories:
• Active alarms: These are alarms that require attention. All alarms that are currently active
appear when you view this category.
• Historic alarms: After an alarm condition has been resolved, the alarm is reclassified as historic.
The 20 most recent historic alarms appear when you view this category.
• All alarms: All active alarms and the 20 most recent historic alarms appear when you view this
category. The alarms are listed in chronological order.
The Alarms screen defaults to active alarms, as in Figure 6, p. 16. Note that the Active Alarms
button in location 5 appears shaded in this figure, which indicates that you are viewing active
alarms. To view a different category, touch Historic Alarms or All Alarms. The button you select
becomes shaded and the list appears.

Sorting Alarms
To sort alarms by a category other than date and time, touch one of the other column headings in
the table. The column heading responds by changing to blue, and the alarms table re-sorts
according to the blue column heading. If you touch the blue column heading again, the column
changes the order from ascending to descending.
You can sort the alarms table by:
• Date/Time (the default sort): Most recent alarms are at the top.
• Severity: Active alarms are at the top (if you are viewing both active and historic alarms),
followed by the most severe, followed by the most recent.
• Description: Alarms are sorted alphanumerically by name, followed by the most recent.
• Status: Alarms are sorted according to active/historic status (if you are viewing both active and
historic alarms), followed by the most recent.

Resetting Alarms
Some alarms require reset to move from the active to the historic state, even if the issue causing
the alarm has been resolved. These manual reset alarms are sometimes referred to as latching

CTV-SVU02A-EN 17
Alarms

alarms. Non-latching alarms change from the active to the historic state automatically, after the
problem has been resolved.
The Alarms screen does not directly state whether the alarms are latching or non-latching.
However, their behavior indicates their type:
• Reset latching alarms by touching the Reset Alarms button at the top of the Alarms screen
(Figure 6, p. 16). Latching alarms respond by disappearing from the active alarms list and
becoming a part of the historic alarms list. However, if the condition that caused the alarm
persists, the alarm will re-appear in the active alarms list.
• You do not have to reset non-latching alarms. Non-latching alarms automatically disappear
from the active alarms list and re-appear in the historic alarms list when the conditions that
caused them are resolved.

Other Alarm Indicators

In addition to the Alarms screen, there are two buttons that indicate alarm conditions. These
buttons are viewable from any screen on the display. You can touch either one to access the Alarms
screen.
• The Alarms button in the main menu area of the screen (Figure 1, p. 7) flashes a color that
represents the alarm level of the most severe active alarm. The three color possibilities
correspond to those of the active alarm icons shown in Table 4, p. 17.
• If an active alarm is present, the alarm indicator button (Table 1, p. 8) appears in the upper left
of the screen, as in Figure 6, p. 16. The icon on this button indicates the level of the most severe
active alarm.

18 CTV-SVU02A-EN
Reports
You can use the Tracer AdaptiView display to view a variety of reports and to create and edit a
custom report. All reports contain live data that refreshes every 2–5 seconds.

CTV-SVU02A-EN 37
Equipment Settings

Setpoint Sources
Some setpoints can be controlled from more than one source. These are referred to as arbitrated
setpoints and are identified by footnote (a) in Table 6. Arbitrated setpoints can be:
• Communicated from a building automation system (BAS)—Refers to a Trane or other BAS that
can communicate with chiller controls over a network.
• Set by an external control source (Ext)—Refers to inputs that are hard-wired directly to local
chiller controls, carrying low-voltage binary (On/Off) or analog (0–10 Vdc,
4–20 mA) signals.
• Set at the front panel (FP)—Refers to inputs that are entered by an operator using the Tracer
AdaptiView display or by a technician using the Tracer TU service tool.

Setpoint Source Arbitration

The Tracer UC800 uses a process referred to as setpoint source arbitration to prioritize the selection
of the setpoint source. See Table 7 for an explanation of how this process works.

Table 7. Setpoint source choices and corresponding arbitration

1. For service or troubleshooting, it may be helpful to set the setpoint source to front panel to isolate the chiller from other control sources.
2. If BAS communication was established and then lost, in most instances the BAS values remain and can be used by the chiller controller.

Security Settings
If security if enabled, the Tracer AdaptiView display requires that you log in with a four-digit security
PIN to make setting changes that are protected by security. This feature prevents unauthorized
personnel from doing so. There are two levels of security, each allowing specific changes to be
made.
You can view all data without logging in. The log-in screen appears only when you try to change
a setting that is protected by security, or when you touch the Log in button from the Settings screen.

Viewing the Settings Screen

Touch the Settings button in the main menu area (see “Main Menu Area,” p. 13) to view the Settings
screen. Security Settings identifies a column on the right side of the screen that contains two
buttons (see the outlined column in Figure 32):
• Security
• Log in (Log out)

Figure 32. Equipment Settings screen with the Display Settings column highlighted

Note: If security is disabled,the Log in/Log out button is not visible. See “Disabling/Enabling Security,”
p. 53.

Logging In
There are two levels of security:
• Security Level 1 allows users to change a limited group of secure settings. The default security
PIN is 1111.
• Security Level 2 allows users to change all secure settings. The default security PIN is 7123.
A technician must use the Tracer TU service tool to define a different PIN, or to recall a PIN that has
been forgotten. When defining a PIN in Tracer TU, the technician enters a 4-digit PIN that
corresponds with the desired level of security.
To log in:
1. Touch the Log in button. The Log in screen appears (Figure 34).
2. Use the keypad to enter your PIN.
• The PIN is a four-digit number, which was configured for your system with the Tracer TU
service tool.
• As you enter the number, the PIN remains hidden by asterisks.
Note: If you enter an invalid PIN, an error message appears on the Log in screen.
3. Touch Save.
• If you viewed the Log in screen from touching Log in on the Settings screen, the Settings
screen appears with a Log out button on it.
• If the Log in screen appeared when you tried to change a setting, you return to that setting
screen.
Note: The PIN is valid until 30 minutes of inactivity passes, or until you log out.
