Overview1.0
The 7” RAC is a color touch-screen display with easy-to-use functionsthat provide a
powerful interface with up to 8 Automatic Transfer Switches equipped with the ATC-
900 controller. It supports serial RS-485 Modbus RTU and Modbus TCP/IPnatively.
When using Ethernet to connect to an ATC-900, a serial-to-Ethernet Modbus gateway
is required such as the PXG-900 or the ELC-CAENET.
The 7” RAC Kit contains the following:

Setup and Wiring3.0
The RAC requires 24VDC power with aminimum current of 360 mA (See “A” below).
There is a terminal block connector on the back of the unit to install wires for the
power. The software comes preloaded onto the unit according to your switch
configuration, and should require no user programming.
The RAC supports Modbus RTU (serial RS-485) and Modbus TCP/IP (Ethernet).
However, since the ATC-900 controller only supports serial Modbus, an RS-485 serial-
to-Ethernet gateway must be used for Modbus TCP/IP. Eaton recommends using the
ELC-CAENET module or a Power Xpert Gateway (PXG-900).
Drawing 66A8395 shows the wiring of the unit over serial Modbus. Consult drawing
66A8395E (or EM) when using Ethernet gateways. All RS-485serial cable must have
three insulated conductors (D0, D1, COM) and one ground(drain) connected to the
shielding of the cable. The Eaton recommended cable is Belden 3106A. Ethernet
cable may be any CAT5/6 certified cable.

Note: multiple Modbus Ethernet gateways may be used to further expand the
communication flexibility of the system. Drawing 66A8395EM should be referenced for
wiring of multiple gateways.
ATC-900 Setup3.1
The communication setpoints on each ATC-900 need to be set as follows:
Baud Rate: 9600, 1-stop, Even
Address: 01, 02, 03, 04, 05, 06, 07 or 08 (each ATC-900 must be unique)
ELC-CAENETEthernet Gateway
PXG-900 Ethernet Gateway

4
Termination SW1: Normally OFF. Should be ON for last controller in the
chain only if using a 120 Ohm resistor on the opposite end of a communication
daisy-chain.
RAC Setup3.2
Your HMI is factory set with communications disabled for all controllers, and
must be enabled during startup. To enable communications, press on any disabled
controller from the Overview screen (or the “System Setup” button on the Controller
screen if you have a single-view HMI). Enter yourpassword (default of 0900). A list of
available controller com links will appear. To name a controller, press the“Edit” button
next to the corresponding controller. To enable communications toa controller, press
the red “Disabled” button under the Coms column; it will change green and display
“Enabled”. To disable communicationsto a controller, press the green “Enabled”
button; it will change back red and display “Disabled”. More detail can be seen in
section 4.0 below.
To change your ATC-900 Setpoints, simply press the orange“Edit ATC # Setpoints”
button, and you will be taken to the first setpoint screen. See section4.6 for more
details.
You can also change items like HMI touch screen force, touch screen calibration, time
& date, brightness & contrast, alarm & touch volume, and others. To do this, you have
two options:
The first is to simply press the small SYSTEM button on theback of the unit for two
seconds. The system menu will now be displayed on the screen. The menus are self-
explanatory but if additional help is required, consult the manual on the Eaton website
called “HMiSoft User Manual” IL04801003E.
The second option is to enter the “System Setup” screen again and press the “HMI
Setup” button. This is useful if the back of the unit is not easily accessible.
HMI Screens4.0
The RAC has a total of 6 screens (5 if using single-view firmware). The following is a
summary of the available screens and their function:
Overview – In a multi-view system, this shows the status of all controllers atonce. This screen is not included if you have a single-view firmware HMI.
Controller View – Shows a more detailed view of a single controller and giveslimited control functionality.
Trend Data (S1/S2/Load) – Shows trend data (voltage, frequency, unbalance,and load current) for each of the sources and load.
Alarms and Events – Shows the user a time and date-stamped list of certainevents and alarms.
System Setup – Allows naming, enabling/disabling coms, and setpoint editingof each controller along with password and HMI setup.
Controller Setpoints – Allows editing of every available setpoint on the ATC-900 controller.
Overview Screen4.1

5
The Overview screen (only available with multi-view firmware HMI) shows the current
status of up to 8 ATS-900 controllers. In the example above, Station 1 is
communicating and shows power connected through S1. Station 2 has timed out and
is trying to reconnect automatically. Station 4 is connected to S2 (preferred source).
Stations 5, 6, and 7 all have various alarm conditions which are displayed by the status
window below each station. Station 8 is disabled per the user.
To view more details and controls for any communicating controller, press anywhere
inside the summary window of the desired controller. This will take you to the
Controller View screen (section 4.2) for that particular controller.
To enable/disable controllers, press on any disabled station window and enter your
password. See section 4.4 for more information on the System Setup screen.
If any controller has an Alarm
condition, an audible alarm will
sound from the HMI. To view the
alarm, press on the alarmed
controller window. Once you are
on the Controller View screen, an
alarm popup window should be
displayed. To silence the alarm,
press “Silence Alarms” button.
To perform a remote alarm reset,
press the “Remote Alarm Reset”
button. To close the alarm
popup, simply press “Close”.

To view the alarm popup window again at any time, press the“ATC-900 IN ALARM”
indicator on the Controller View screen.
Controller View Screen4.2
The Controller View shows a much more detailed view of a single controller. Note: this
will be the default screen for a single-view firmware HMI. The top area contains a
status grid with 6 indicators. Status indicators change from gray to a yellow or red
color when active.
Below the status indicators are the
Source 1, Source 2, and Load detail
windows. These windows include
graphical and numerical represen-
tations of voltage, frequency, and
phase loss/unbalance as well as
status indication and a trend screen
button (Section 4.5). If your
controller has a DCT Module add-
on, you will see additional Load
metering including kilowatts, kVAR,
kVA, power-factor, and three-phase
current.

Voltage/Freq./Phase-loss/
Unbalance Indicators

7
The voltage, frequency, phase-
loss, and unbalance indicators
have been designed to show a
quick graphical representation of
how ‘healthy’ the source is. The
top grey area indicates the Over-
voltage or frequency dropout
range. The bottom grey area
indicates the Under-voltage or
frequency dropout range. The
middle light-blue area indicates
the “good” range. These areas resize dynamically depending on how the dropouts are
set in the ATC-900’s setpoints. If the voltage or frequency reaches the upper or lower
ranges, they will turn from grey to red, indicating a problem. Note that the numerical
value will change to “N/A” if the value is ever invalid (e.g. Vbc, Vca, and Unbalance in
a single-phase system.)
Below the Source 1, Source 2, and Load status windows is
the Source Sync window. On three-phase systems, this
window will display how far apart the two power sources are
from each other. The difference is given in Volts, Frequency,
and Phase. When closed transition or in-phase is enabled
on the ATC-900, the allowable range will be shown on the
bar graph. If the difference is higher than the allowable
range, it will turn from grey to red, indicating that it is not okay
to do an in-phase or closed transition at that time.
Note that there are different indicators for closed (CT) and in-
phase (IP) transitions for Frequency and Phase Difference.
To the left of
the Source Sync window is the Mimic
Bus window. This window acts
identically to the mimic bus on the
System Overview screen. The upper
banner displays the name of the
selected controller. The bus area shows
which source is available, preferred, and
connected. Active lights are white, while
inactive lights are black. The currently
energized bus is depicted by a light-blue
colored line.
To the right of the Mimic Bus area
is the Manual Retransfer window.
This area indicates whether
manual retransfer is enabled or
disabled, as well as alerting the
user if the ATC-900 is waiting for a
manual retransfer signal. The manual retransfer can be initiated remotely by pressing
the button labeled “Press to Retransfer” when it appears on the HMI.

The bottom area of the screen shows navigation buttons along with the “Show Manual
Controls” button. The “Back to Overview” button navigates to the Overview Screen
(Section 4.1). Note: this button is not available in the single-controller firmware. The
“Event History” button navigates to the Alarm/Events Summary screen (Section 4.3).
The “System Setup” button navigates to the System Setup screen (Section 4.4).
The “Show Manual Controls” button expands a small area with 3 controlbuttons: Go to
Emergency, Bypass Timers, and Start Engine Test. All control is password protected
except Bypass Timers. To hide the manual controls, press the“Hide Manual Controls”
button.
Engine Test Button
To initiate an engine test from the RAC, press theStart Engine Test button and enter
your password. The ATC-900 will signal the generator to start. Once the generator
has reached nominal voltage, it will run until the Engine Test Run Time expires
(adjustable in the ATC-900). If your ATC-900 is programmed for Load Transfer, then it
will also transfer your load to the generator during the engine test. To abort the test
early, push the Cancel Engine Test button on the RAC.
Go to Emergency Button
To initiate a go to emergency command from the RAC, press the Go toEmergency
button and enter your password. The ATC-900 will initiate a transfer to your non-
preferred (emergency) source. To go back to your preferred (normal) source, push the
Cancel Go to Emergency button. If you have Manual Retransfer enabled, the“Press
to Retransfer” button will appear (see below).
Manual Retransfer Button
The Manual Retransfer button allows the ATC-900 to transfer back to the preferred
(normal) source. It functions the same as the physical Manual Retransfer pushbutton
located on the ATS front device panel(if equipped). Note: this RAC pushbutton is only
visible when the ATC-900 is waiting for a manual retransfer input, otherwise it will not
appear. If manual retransfer is disabled on the ATC-900, the button will never be
displayed.
Bypass Timers Button
The Bypass Timers button allows the user to skip a currently active timer. While a
timer is counting down, simply press the button, and it will be bypassed. This button
works for the following timers:
Time Delay Normal-to-Emergency (TDNE)
Time Delay Emergency-to-Normal (TDEN)
Time Delay Neutral (TDN)
Time Delay Engine Start (TDES)
Time Delay Engine Cooldown (TDEC)
Time Delay Pre-transfer (TDPRE)
Time Delay Post-transfer (TDPOST)

Alarm and Events Screen4.3
The Alarm and Events screen displays time/date-stamped alarms (in red) and events
(in black) for all connected controllers.This information is stored in the HMI’s memory,
and will not be erased if the unit is powered down. Therefore, a“Reset History”
pushbutton is provided to clear all historical events and alarms if needed. A list of all
available messages is shown below.
