Operator and Installation Manual Energy Command 30 English 12-2007 900−0541 (Issue 3) (Cummins PN 018-01049 Rev 1.
Operation and Installation Manual PN 018-01049 Rev 1.6c Energy Command 30 • General The Energy Command 30 (EC-30) is an Automatic Generator Starting (AGS) System that provides both automatic and manual control of Onan Diesel, Gasoline, and Liquid Propane (LP) engine driven AC generators (referred to in this manual as a genset). EC-30 also provides critical system information such as the battery state-of-charge, key operational information such as quiet time, genset service and fault messages.
OPERATION PANEL QUICK REFERENCE START/STOP: Works exactly like the genset switch. If the genset switch has a run light and flashes diagnostics, the EC30 run light will also be on when the genset is running, flash during preheat, and flash genset fault messages. UP/DOWN: This key is used to scroll through display choices and change values that can be SET. ENTER: This key is used to store values that have been changed, and to respond to display commands.
Operation of the Energy Command 30 the value. Press ENTER to store the new value. Also see Setting Local Time. Overview This section describes how to use the Energy Command 30 (EC-30). The Quick Start page defines key locations and Figures 1, 2, and 3 are the display screen flow charts. ENTER Key ENTER is used to store a value that has been changed. It is also used to ENTER the SETUP & INFO DISPLAYS. The ENTER key may also be required to exit a screen or to acknowledge an action.
• When the safety input signal changes from off to on (or on to off), EC-30 stops the genset and changes the genset operating Mode to MANUAL. This prevents unexpected automatic starting indoors or in confined spaces. Verify the vehicle is in a safe location, and then use the AUTO GEN key to select AGS AUTO ON mode. Brake: Brake light for all trailer, 5th wheel, and pickup camper installations, or air brake on diesel motor homes.
Adaptive Cycle Management House Battery Charge Level Indicator The automatic modes have unique features to minimize repeatedly starting and stopping the genset, also called short cycling, and to pre-fill the battery prior to the start of Quiet Time. The house battery charge level indicator uses both short and long term voltage trends to determine the battery level. It is intended as a guide to the state-of-charge (SOC) of the battery and its ability to sustain the load.
The SERVICE DUE message is displayed as soon as the service interval has elapsed. The UP/DOWN key still allows navigation through the main displays and all functions still work. After the genset is serviced navigate to the SERVICE DUE message and ENTER to reset the service interval hour-meter. If the genset is serviced prior to the next service reminder, go to the SERVICE IN display and press SET, press ENTER to reset the service interval hour-meter.
Setting Up and Testing the Energy Command 30 Overview This section describes how to Setup and Test the EC30. Before using the EC-30 for the first time check to be sure that the unit is setup appropriately for the system. The character < is used to indicate all default values. Also see Figures #1-4. The Safety Input is described in detail in the Installation section of this manual.
ENTER. Now navigate to the SETUP GENSET display and press ENTER. The GEN TYPE will be displayed. Press SET, the display will flash. Use the UP/DOWN key to select the GEN TYPE and press ENTER when the appropriate type is displayed. The GEN TYPE is stored in permanent memory and will not have to be changed unless the EC-30 is installed on a different type genset. SYSTEM INFO Display The SYSTEM INFO display allows access to key information.
• • Brake: Brake light for all trailer, 5th wheel, and pickup camper installations, or air brake on diesel motor homes. Park: The park signal/neutral (transmission) from motorized motor homes or van conversions. Press ENTER to store in permanent memory. This will not have to be changed unless the type of safety input is changed or the EC-30 is installed in a different application.

Installing the Energy Command 30 Overview Specifications This section describes how to install the Energy Command 30 (EC-30). Operating Temperature: Storage Temperature: Battery System: Voltage Range: Typical Current Draw: L x W x D: General This system is only for use with Onan Recreational Vehicle genset (Quiet Diesel gensets, and Gasoline/LP gensets). The control circuitry is a 3-wire ground to start/stop type.
Wires must be protected from all hot, sharp, and abrasive surfaces. 2) Prepare the chosen location for the genset controller. a. Use scissors to cut out the template. b. Tape the template to the mounting surface to be cut out, make sure that the template is “square or level” with the mounting surface. c. Using a center punch and a hammer, punch a mark through the template for each fastener and at the perimeters of the cutout area. d. Remove the template.
Wiring Installation 1. Use wire tags or labels to label each end of every wire. Use Figures 5 and 6 to determine the correct labels and connections. 2. At the controller end of the harness, insert the terminated and labeled wires into the correct positions in the connector body. Use Figures 5 and 6 to determine the correct positions. 3. At the genset end of the harness, insert the terminated and labeled wires into the correct positions in the connector body.
WIRE #9 Engine Battery Sense 12-24VDC: This wire supplies the positive sense voltage for the engine starting battery. This is an optional feature. The engine battery voltage will only be displayed if it is connected. It must be connected directly to the battery. It must be protected by a 5A inline fuse located as close to the battery as possible. Do not install the fuse until the installation is complete. Install fuse just prior to testing the installation.
This input should be treated like a relay coil input, or a light bulb. It must be supplied with both a positive and a negative. The actual safety switch (ignition, park brake, or transmission park switch) may be located in the positive or negative side of the circuit. These inputs may be wired to be active (on) when supplied with a negative or positive input. If supplied with a positive input connect #15 to negative. If supplied with a negative input connect #16 to +12V.
Troubleshooting If controller functions do not operate properly, proceed as follows;. 1. Does the genset operate correctly from the genset controls? If it does not, the problem is in the genset, not the EC 30 controller. See the genset Operator, Installation, and Service Manuals. . 2. If the genset operates correctly from the genset controls, Confirm that the correct connection diagram (Figures 5, 6 and 7) was used, then check EC 30 wiring connections. 3.

The mounting footprint for the control is shown below. Select an appropriate mounting location, make sure there is enough room to install the control panel, and mark the locations for the cutout area and the mounting holes, as indicated in the illustration. Use a center punch to mark the perimeter of the cutout area. Depending on the tool to be used (Roto-zip tool recommended, reciprocating saw, or key hole saw), determine where to drill the corner starting holes.
