LCD Programming Procedure

1. Press the SEL key to begin. The Eaton logo will be displayed.

After a few seconds, the

INITIAL STATUS

screen will be displayed.

If the screen’s contrast is not adjusted properly, you can press and

hold the

button to lighten the screen and press and hold the

DOWN

button to darken the screen.

2. Login

If user passwords have been created on your system by your distrib-

utor/installer, you will see the following screen. Use

UP/DOWN

enter the letters of your password/access code and the

SEL

key to

advance to the next letter. Advance the cursor past the end of the

blanks to submit the password/access code.

If this LCD tool has just been powered up, it will have to download a

database from the PRC750 controller. You may see the following

screen with the progress indicator:

The database may take about 10 to 20 seconds to download during

initial startup. Afterward, the

MAIN MENU

will be displayed. To bypass

the

REFRESHING DATABASE

screen, press the

BACK

key. The

refresh continues in the background.

3. Veriﬁcation of Hardware

Verify that the Breaker Control Buses (BCBs) are properly addressed

and all necessary communication wiring has been terminated. Please

reference the PRC750 Installation Guide (IL01412008E.pdf) for fur-

ther directions on how to address the BCBs and properly connect

them to the PRC750 controller.

4. Discover Breakers

Discover breakers is located in the main menu. The ﬁrst time the

Pow-R-Command Control Unit is powered up, it automatically

“discovers” the breakers that are connected to it through the Breaker

Control Buses (BCBs). This assumes that the addresses on the BCBs

have been set correctly (please see Step 3 above). Upon startup, a

good practice is to bypass all of the breakers ON and then OFF to

ensure proper communication and discovery. If the breakers have not

been discovered or the BCBs have not been addressed correctly,

then some or none of the intended breakers will operate. These sim-

ple steps can be performed in two ways: manually and through the

LCD display via the

ADVANCED MENU

MANUAL

When the LCD face is removed from the PRC control unit, the inner

circuitry and contacts are exposed to plain sight. Referencing the

drawing below shows the location of 5 pushbuttons that, when

depressed and held for 5 seconds each, perform various control

functions.

From left to right, the buttons are

RESET, BYPASS ON, BYPASS

OFF, BYPASS CLEAR

and

FIND LOADS

respectively. Before testing

the breakers and communication, press and hold the

FIND LOADS

(furthermost right) button for 5 seconds. After which, the

BYPASS

and

OFF

buttons can be pressed and held for testing purposes.

Should there be any problems, to check for proper operation of all

breakers, each breaker has a red indicator for ON, check the wiring

and communication cables, as well as the BCB addressing. Upon a

successful test, make sure the

BYPASS CLEAR

button (2nd from

right) is pressed and held for 5 seconds to relinquish the overridden

state to the direction of the control unit once again.

Note:

When any load in the panelboard has been

BYPASSED ON

BYPASSED OFF

, a green bypass LED on the front of the controller will

be lit. When loads are bypassed, they will not follow schedule and/or

switch commands.

Troubleshooting Guide / FAQ

General Troubleshooting

Symptom 1: The text on the LCD display is not visible/legible. There

is a blue backlight, but the text is washed out.

Cause: The contrast on the LCD needs to be adjusted.

Solution: Press the BACK key multiple times to ensure that you are

on the very ﬁrst screen of the LCD. Press the SEL key one time.

Press and hold the UP arrow. The contrast should begin to lighten.

You can make the contrast darker by pressing and holding the

DOWN arrow. The contrast can also be adjusted from within the

ADVANCED MENU.

Symptom 2: One or more Smart Breakers are not showing up in

CONFIGURE GROUPS.

Causes:

1. Subnetwork wiring from controller to each BCB in master and

expansion panelboards is not properly pulled/terminated.

2. BCBs are not properly addressed via DIP switches on each BCB.

3. Smart Breaker has not properly been connected to BCB

breaker port.

4. Breakers have not properly been discovered.

Solution:

Step 1: Make sure all subnetwork wiring from controller to each BCB

(including expansion panelboards) is properly terminated. (See Figure 2.)

Step 2: Ensure that each BCB is properly addressed via the DIP

switches on each BCB. (See Figure 3.)

Step 3: Make sure that each Smart Breaker is properly terminated

onto each BCB Breaker Port. Each Smart Breaker has a 4-pin connec-

tor that slides onto each 4-pin breaker port on the BCB. It is very easy

to misalign this connection.

Step 4: Discover breakers. Please reference the LCD Quick Start

Guide for complete details on how to properly discover all Smart

Breakers.

Note: If Smart Breaker(s) still do not show up in conﬁgure groups

after completing these steps, please call the PRC Technical Support

Line at 1-888-252-6286, Option 3.

Documents to Reference:

1. Instruction Leaﬂet (IL01412012E).

Symptom 3: After completing the above steps, one or more Smart

Breakers are not responding to issued commands.

Note: Make sure all the above steps have been completed before

proceeding.

Causes:

1. The Smart Breaker(s) has/have been Overridden.

2. The black primary handle to the breaker is in the OFF position.

Deﬁnition of Overridden: Breaker is taken “out of service” or taken

out of normal operation. This means that the Smart Breaker will not

follow any issued commands. The breaker must be restored and put

back into service/normal operation to follow issued commands.

Solution:

1. Take a look at the status LEDs on front of the controller. They are

located next to the power switch to the controller. There will be

three LEDS. The top LED represents the power to the controller.

This LED is red and should be constantly ON. The middle LED is

the “override” LED. If any one of the Smart Breakers are overrid-

den, this LED will be lit. This LED is green. The bottom LED is

the network LED. It will blink RED during normal operation.

If the middle LED is lit/green, this means that the Smart

Breaker(s) is/are overridden and need to be restored back into

service. From the MAIN MENU of the LCD, scroll down and

select BYPASS LOADS ON/OFF (this should be the last option on

the MAIN MENU). Next, scroll down and select CLEAR BYPASS.

2. If it is safe to energize the load connected to each Smart Breaker,

ensure that the black primary handle to the breaker is in the ON

position. The Smart Breaker will not properly respond to issued

commands when the black primary handle is in the OFF position.

Symptom 4: I have a 30-circuit panelboard, and my Smart Breaker

positions on the left side are not numbered correctly from within

the LCD.

Cause: The controller needs to be conﬁgured to represent the type of

panelboard that it is controlling (i.e., 42 circuit, 30 circuit, etc.).

Solution: The controller needs to be conﬁgured to represent the type

of panelboard that it is controlling. In this case, the controller needs to

be conﬁgured to control a 30-circuit panelboard. All controllers default

to control a 42-circuit panelboard. To adjust this setting, the following

steps need to be taken:

1. From the MAIN MENU, scroll down and highlight, but don’t

select, BYPASS LOADS ON/OFF. Hold the BACK button for about

5 seconds.

2. An ADVANCED MENU item will appear. Scroll down and select

ADVANCED MENU.

3. Scroll down and select SUBPANEL CONFIGURATION. Here, you

should see a list of BCBs and their addresses. (If nothing shows

up on the BCB list, please stop and go through the steps

depicted in Symptom 2 above and then continue.)

4. The BCBs should be split into left and right for each panelboard.

Highlight the ﬁrst BCB that needs to be conﬁgured for a 30-

circuit panelboard. Press SEL.

5. Scroll down to TYPE and press SEL. If this BCB is a left side

BCB, then SEL LEFT-30. If it is a right side BCB, then SEL

RIGHT-30.

6. Repeat for the remainder of BCBs that need to be conﬁgured for

30-circuit panelboards.

Indicator Lights/LEDS

The LEDs on the controller and BCBs can be used to help diagnose

an issue with the current setup of the system.

Symptom 1: Power LED not lit on controller when the power switch

is toggled on.

Causes:

1. No ac voltage to the controller transformer.

2. Incorrect voltage to the control transformer.

3. No 24 Vac voltage to controller unit.

4. Blown fuse within the controller.

Solutions:

1. Make sure there is ac voltage to the control transformer, and it is

the correct amount.

2. Controllers are available in various voltages. Check the trans-

former label for the correct input voltage.

3. Press the reset on the transformer, there will be a noticeable

click if it resets. The transformer may have tripped, if the trip

state continues after resets this is a sign of other issues. Make

sure no wires are pinched or shorted coming from the controller.

If none found, please contact technical support.

4. Check the plug on the right side of the controller for proper con-

nection of the 24 Vac from the transformer. If plugged in, check

for 24 Vac at the plug.

5. Check the internal fuse in the unit. It is located behind the face-

plate. Four screws must be removed to gain access to the fuse.

Check the status of the fuse in the lower right hand corner of the

unit. If this fuse is blown, it needs to be replaced.

Symptom 2: Power LED lit on the controller but not lit on BCB when

the controller power switch is toggled on.

Causes:

1. No connection from the controller to BCB.

2. Incorrect wiring on the BCB from the controller.

3. Problem with the output voltage from the controllers.

Solutions:

1. Check the plug on the BCB and the controller for proper

connection.

2. Check for correct wiring of the BCB; see the side of the control-

ler and BCB for proper connections. Also, the connections are

included in the Instruction Manual.

3. Check for 24 Vac from the controller; see the label on the side of

the controller for the correct pins of the 4-pin connector. If volt-

age is not present, please contact PRC Technical Support Line at

1-888-252-6286, Option 3.

Symptom 3: The “POWER” LED and the “LAN” LED are lit, and the

“RUN” LED blinks twice every few seconds on the BCB.

Cause: There is a communication failure between the controller and

BCB caused by incorrect wiring of the BCB.

Solution: Check wiring (L+ and L- may be crossed or 24V~ and COM

may be crossed from the controller to the BCB).

Symptom 4: The “POWER” LED is lit, and the “LAN” LED ﬂickers

every so often with the “RUN” LED blinking twice every few

seconds on the BCB.

Cause: There is a communication failure between the controller and

BCB caused by incorrect wiring of the BCB.

Solution: Check wiring; L- may be disconnected.
