1 Pow-R-Command 750 LCD Display Quick Start Guide Instruction Leaflet IL E Effective February 2009 Introduction This is the Quick Start Guide for the PRC750 LCD programming display. A worksheet of information that will be needed to complete this startup is found on Page 11 of this guide. Make sure you have all the listed information available before starting, either by filling in the worksheet, or from job documents. Several conventions are used in this document. COURIER text indicates screen output or screen menu items. BOLD COURIER indicates user button presses. Navigation through the LCD programming menus is via the four buttons to the right of the screen as shown above. They are BACK, UP, DOWN and SEL. Generally, BACK is used to cancel a selection or to move back up through the menu hierarchy. UP/DOWN are used to scroll through selections on a menu or to change values. SEL is used to choose a menu item or to enter a setting. Some menu screens will have an arrow symbol ( ) in the lower right corner. This indicates there are additional menu items for this screen. Use the UP/DOWN keys to scroll down to view the additional items. Primary Handle Control Handle FIGURE 1. CONTROLLABLE CIRCUIT BREAKER Eaton s Cutler-Hammer controllable circuit breakers have two handles, as shown in Figure 1. The larger black handle is referred to as the primary handle. The primary handle can be turned to the ON or OFF positions by manual control. The smaller green handle is referred to as the control handle. The control handle can be moved to the ON or OFF position by electronic control or to the ON position by manual override.

2 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 UP button to lighten the screen and press and hold the DOWN button to darken the screen. Jan 10, :28A Group Status: ON: ABC N OFF: DEFGHIJKLM OP Press SEL for menu 2. Login If user passwords have been created on your system by your distributor/installer, you will see the following screen. Use UP/DOWN to 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. 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 (IL E.pdf) for further 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 simple 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. Jan 10, :28A Please Enter 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: Jan 10, :28A Refreshing Database Please wait... 57% 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. Note: In doing this, the load status table and group data will not be refreshed until the refresh is complete. 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 ON 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. MAIN MENU Command Groups ON/OFF Panel Status Screen Configure Groups Configure Date/Time Group Status: ON: ABC N OFF: DEFGHIJKLM OP _ Note: When any load in the panelboard has been BYPASSED ON or BYPASSED OFF, a green bypass LED on the front of the controller will be lit.

10 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 connector 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 , Option 3. Documents to Reference: 1. Instruction Leaflet (IL E). 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 overridden, 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. FIGURE 2.

11 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 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 transformer 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 connection 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 faceplate. Four screws must be removed to gain access to the fuse.
