Ethernet Remote
Annunciator
Controller (RAC)
Instruction Sheet for
Automatic Transfer
Switches (4 x ATS)
Revision: 01
IB01602082E
1.1 Ethernet Remote Annunciator Controller (RAC) using the up to 4 ATC-300+
connected via RS-485 to TCP/IP gateway
The 7” RAC is a color touch-screen display with easy-to-use functions that provide a
powerful interface with up to 4 Automatic Transfer Switches. It not only displays the
status of the switch, it also provides several popular control functions.
The 7” Ethernet RAC Kit contains the following:
HMIVU07CUNBE (7” Color HMI Display)
IL04801003E (HMI Instruction Leaflet)
IB01602080E (Ethernet RAC Setup Document)
OR IB01602081E (Ethernet Multiple Gateway RAC Setup Document)
ELC-PS01 or 02 (Optional 24VDC power supply)
PXG-400E (Ethernet to RS-485 Gateway)
IB10602082E (This Instruction Sheet)
66A8395E [or EM] (HMI Ethernet Wiring Drawing for the ATC-300+)

•History of Alarm
Control Type
•Go to Source 2 (Emergency)
•Go to Source 2 Abort
•Engine Test
•Engine Test Abort
•Silence Alarm
•Bypass TDNE/TDEN
•Manual Retransfer
1.3 Set-up and Wiring
The RAC requires 24VDC power with a maximum current of 125 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, and should require no user
programming.
Communication with the ATS controller is accomplished via Modbus RS-485 serial
network to the gateway. Drawing 66A8395E shows the wiring of the unit, which
includes the power connection and the communication daisy chain network. The
cable used should have two insulated wires and one ground connected to the shield of
the cable. The recommended cable is a CAT5E type but there are many similar
shielded cables that can be used. The drawing also shows the connection between
multiple controllers and the PXG-400E gateway. The gateway connects to the HMI’s
LAN port using a standard Ethernet CAT5E cable.
Note that multiple gateways may be connected to a single HMI unit over Ethernet to
further expand the communication flexibility of the system. Drawing 66A8395EM
should be referenced for wiring of multiple gateways.

The setpoints on each ATC-300+ needs to be set as follows:
Baud Rate: 9600
Address: 01, 02, 03, and 04 (different address for each ATC-300+)
Terminated: On (termination micro-switch on back side of the last ATC-300+)
There is a system menu on the HMI that allows the operator to change items like
touch screen force, touch screen calibration, time & date, brightness & contrast, alarm
and touch volume, and others. The HMI should be set up so the user will not have to
adjust anything in the field. If a change is desired, there are two ways of
accomplishing this:
The first is to simply press the small SYSTEM button on the back of the unit for two
seconds. The system menu will now be displayed on the screen. The menus are self-
explanatory but if help is required, one can download the manual from the Eaton
website under “HMiSoft User Manual” effective February 2011. After the adjustments
have been made, simply push the SYS button again for two seconds. Also see the
instruction leaflet IL04801003E that came with the display.
The second option is to push the “SETUP” button and the new screen that appears
will have a “SYSTEM SETUP” button. This is useful if the back of the unit is not easily
accessible. This button will get the user in the same area as the SYSTEM button on
the back of the unit.
1.4 Screens
There are six screens that are displayed for the ATS functionality. Each screen has a
return button to return to previous screen. Each of the screens and the associated
buttons are described below.
Screens:
Top Level with ATS Select and System Setup

5
Second Level with S2 Connected, Alarm, and Non-Auto
The top level screen shows the current status of up to 4 ATS controllers. In the
example above, Station 1 is communicating and shows power connected through S1.
Station 2 was enabled, but has lost communication to the controller. Station 3 is
disabled entirely, as it may not exist, or it is down for maintenance. Station 4 is
communicating and shows power connected through S2. To enable/disable any
controller, press the setup button (password protected – level 3).
To continue to the second level for any working controller, simply press on its
corresponding quadrant. If the system switches to emergency (S2), an audible alarm
will sound from the HMI. To silence the alarm, simply press the Silence Alarm button.
The alarm flag will still be present, but the audio will be off. The volume of this alarm
can be controlled in HMI system setup. To determine when S2 was connected and
other alarms, press the Alarm Data button to display the next screen shown below.
Data Screen
The Data Screen shows the voltages and the frequency for each of the three phases.

6
Alarm Data (Messages)
The Alarm Data screen displays the S2 alarm history as well as other alarms shown
below. The Alarm history displays an O or an X at the beginning to display when the
unit was true or false; S2 connected (O) or S2 back to S1 (X). To clear the
information, simply push the Clear History button.
ALARM Messages
1. Overvoltage
2. Undervoltage
3. Over Frequency
4. Under Frequency
5. Plant Exerciser
6. Engine Test
7. Remote Engine Test
8. Voltage Unbalance
9. Phase Reversal
10. Go to Emergency
11. Lockout
12. Failed to Sync (phase angle)
13. Failed to Sync (frequency difference)
14. Engine Test or Plant Exercise
15. Source 1 Error
16. Source 2 Error

Initial Setup Screen
The initial setup screen allows the user to type in a name for the ATS controller. This
name will be displayed throughout the HMI status screens, and is for aesthetic
purposes only. The user can also disable the com link by pressing on the green circle.
Password Table Pop-up
Passwords are needed to get to the Engine Test and Go to Emergency (To S2)
screens. These two screens are at security level two which is factory set to AC44. If
you would like to change any of the passwords, navigate to the password table in the
SETUP screen (you must input 0300 which is the level 3 password). If you change it,
do not forget the level 3 password or you will be unable to edit passwords in the
future.
To enter the password table: 0300
To run an engine test: AC44
To transfer To S2: AC44

8
Engine Test
By pressing Start Test, the controller will start the generator and then run the engine
test when S2 is available. (Push the Silence Alarm button to remove the audio). To
abort the test before the time is up, push the Abort Test button. One can use the
Bypass TDNE/TDEN if desired.
Transfer Control
By pressing the Go To S2 button, the switch will transfer to source 2 if there is
available power on S2. To go back to S1, push the Return to S1 button. One can use
the Bypass TDNE/TDEN if desired. The Manual Retransfer button will appear if the
controller has manual retransferring enabled. Pressing it will send the command to
the ATC-300+ controller, but only if it is enabled.
CAUTION
This is a remote control device. Caution should be applied to make sure that
appropriate procedures are in place for Engine Tests and To S2. Appropriate

9
procedures include, but are not limited to, switch doors being closed and latched,
personnel knowledgeable of transfers, and other site safety recommended
procedures.
