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:

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.

PXG-400E Gateway

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

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.

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

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

procedures include, but are not limited to, switch doors being closed and latched,

personnel knowledgeable of transfers, and other site safety recommended

procedures.
