1 E-MAAX DC Charge Controller System Installation & Operations Manual November 2014 Pre-Production Revision 1.0 Introduction Thank you for choosing the E-MAAX DC Charge Controller System. The E-MAAX is the most advanced charge control system available for 12 or 24-volt N or P-type externally regulated marine alternators, and is the ideal choice for systems requiring precise voltage control for optimal battery charging. The E-MAAX DC Charge Controller System is available in three configurations; the Basic System which includes the CPU module, two battery temperature sensors and an alternator temperature sensor. The E-MAAX Cruiser system includes the CPU module, remote control panel, temperature sensors for two battery banks, and an alternator temperature sensor. The E-MAAX Voyager Pro system includes a premium CPU with circuitry for amperage monitoring, a remote panel which can be used as a battery monitor as well as alternator charge control access point, as well as temperature sensors for two battery banks, an alternator temperature sensor, and high-amperage shunts for current reading. All kits include a distribution module module for simplified sensor wiring. In addition to the components included with the Charge Controller systems, E-MAAX sensor bugs are available for a multitude of functions, including temperature sensing, relay functions, switching, fusing and audible alerts. Electromaax is currently developing a number of new sensor bugs to add even greater functionality to the E-MAAX system. Unlike previous marine voltage regulators, which required the installer and user to make programming adjustments in the engine compartment or other difficult locations, the E-MAAX system enables the user to make programming adjustments at a convenient remote panel installed at the helm or navigational system. The remote panel can also provide important information while the system is working, including charging voltage, alternator and battery temperatures, charging stage, and a wide range of additional measurements, based on how the charge controller is equipped. The Voyager Pro system provides the additional ability to monitor amperage going into the batteries and current loads required for ship s functions making it possible to accurately determine system demands and battery capacity.

2 Safety Issues Before getting started with the installation process, we would like to offer the following safety guidelines to ensure optimal protection for the installer, the operator, and vessel occupants. Failure to follow these guidelines could result in injury or damage to your vessel s electrical system. The following instructions are provided for use by experienced marine electrical installers. If you are not experienced with marine electrical system repair or installation, we recommend hiring a qualified electrician for installation. 1. Always disconnect your batteries and turn your battery switches to their OFF positions prior to commencing with work on the vessel s electrical system. 2. Remove any loose fitting clothing or jewelry which could become entangled with the engine or other moving mechanical systems. 3. Wear ANSI-approved safety glasses or other appropriate protective eye wear. 4. Ensure that the engine has cooled sufficiently before attempting to install the alternator. 5. DO NOT install your high-output charging system without ensuring that your electrical wiring is of sufficient gauge to handle increased amperage loads. 6. Ensure that your work area is properly ventilated and that no fuels or flammable solvents are present in and around your work area. 7. DO NOT operate your charging system without proper fusing. Failure to do so could result in severe injury and/or damage or loss of your vessel. 8. DO NOT attempt to install or repair electrical system components while under the influence of alcohol or medications that could impair judgement or agility. 9. Use the right tool for the job. Use of improper tools could result in damage or injury. 10. Take time to read the manual. Failure to do so could result in damage or injury, and could affect warranty protection. Installation Basic System The E-MAAX Basic System is intended for P-type 12-volt applications where no user intervention is required. This would be typical of fleet or charter applications where a preset battery program (preprogrammed for AGM batteries) is all that s required and alternator and battery temperature sensors are used to modify charging based on ambient temperatures. The Basic System is provided with a CPU (voltage regulation) module and three temperature sensor bugs; two for battery banks and a temperature sensor bug for the alternator.

3 ule. The footprint of the CPU module is approximately 3.5" x 4.5". A flange at the bottom of the CPU module enclosure enables the module to be mounted to a flat surface like a stringer or bulkhead. The CPU module should be located within approximately eight feet of the alternator. Four wires need to be connected between the CPU module and the remainder of the charging system: 1. Ground (Black) Must be connected between the Ground Terminal on the CPU and system ground. 2. Power (Red) Must be connected between the Power Terminal on the CPU and a constant source of positive battery voltage (12+ volts). Connect to alternator positive output post or the positive post of the battery that s connected directly to the alternator. 3. Field (Blue) Connects to alternator s external field terminal. This version of the E-MAAX is programmed specifically for use with a P-type alternator which is excited on the positive brush. 4. Ignition (Brown) Connects to the ON side of the engine ignition switch which is only active when the switch in in the run position. This wire can also be connected to a switch that s activated by engine oil pressure. In addition to the four main wiring connections, the Basic System includes sensors which monitor temperature at the alternator and at two battery banks. A distribution bug provides a centralized location for wiring connections between the CPU and the individual sensors. The following diagram illustrates a typical installation: Installation E-MAAX Cruiser & Voyager PRO Systems Where the Basic System is perfect for applications where no user control is needed, Electromaax s E- MAAX Cruiser & Voyager PRO Systems offer expanded user control via the E-MAAX Remote Panel. Mounted in a convenient location, the Remote Panel provides an easy-to-use solution for basic and advanced programming functions, as well as access to a wealth of accurate charge profile information. To install the Cruiser or Voyager PRO System: 1. Identify the installation location for the CPU module. The installation should be in a location that s cool and dry, within roughly 10 feet of the alternator. The CPU module is flanged, with mounting holes on both ends of the CPU enclosure. Typical mounting locations are on bulkheads close to the engine compartment. The ideal ambient operating temperature for the CPU is <120 F. 2. The Remote Panel is equipped with a 15-foot multi-conductor

4 cable for connection to the CPU module, but can be replaced with a 22/3 tinned multi-conductor cable measuring up to 30 feet long if a greater distance between the CPU module and the Remote Panel is required. A rough panel opening of 3.5"H x 4"W is required for a flush-mount Remote Panel installation. 3. The CPU Module provides three connection points marked as PANEL on the terminal connection strip. The multi-connector cable includes three wires; a 5V power source (RED), a data connection (GREEN), and ground (BLACK). These three wires must be connected between the CPU module and the Remote Panel. 4. Once the Remote Panel and CPU module are connected, the CPU module can be connected to the alternator and positive/negative battery connections. Four wires must be connected between the CPU module and the electrical system; power, ground, ignition and field. 5. The (BLACK) ground wire should be connected to system ground. Typical connection points would include a ground bus, a negative battery post, alternator ground terminal, or the engine block. A 14-gauge tinned marine grade wire is recommended. 6. The (RED) power wire should be connected to the positive side of the battery (or batteries) being charged, and should always see battery voltage. Typical connection points would include the positive post of the battery being charged, the positive output post of the alternator, or a positive bus that s connected to the battery being charged. If a battery isolator is being used to charge multiple To System Ground To Battery + To Alternator Field To Ignition Switch GROUND (BLACK) POWER (RED) ALT. FIELD (BLUE) IGNITION (BROWN) banks, the power wire should be connected to the output post of the battery isolator that s supplying power to the largest battery bank. The power wire should be 14-gauge tinned marine grade wire if overall length is six feet or less, or 12-gauge wire if the overall length is between six and 10 feet. A 10-amp ATC type fuse should be installed at the source end of the power wire. 7. The (BLUE) alternator field wire should be connected between the CPU module s Alt. Field terminal and the external field wire connection on the alternator. The field wire should be 14-gauge tinned marine grade wire if overall length is six feet or less, or 12-gauge wire if the overall length is between six and 10 feet. The E-MAAX Charge Controller System is designed to be used in either positive (high) or negative (low) field excitation modes. Programming for positive or negative field POWER

5 excitation is discussed in the Programming section of this instruction manual. Be sure to determine the excitation polarity that s correct for your externally-regulated alternator. 8. The (BROWN) switched ignition wire must only see battery voltage when the ignition switch is in the ON position and/or when the engine is running. Typically, the ignition wire is connected to the ON (RUN) side of the ignition switch, or it can be connected to a switch that s activated by rising engine oil pressure. The ignition wire should be 14-gauge tinned marine grade wire. Standard and Optional Sensors and Bugs One of the most unique, and innovative features of the E-MAAX Charge Controller System is its ability to integrate a variety of bugs to add functionality to the system. Ranging from temperature sensors to alarms, to independent relay modules, these bugs take the E-MAAX system far beyond the limits of simple voltage regulation. All E-MAAX system packages include alternator and battery temperature sensor bugs, as well as a distribution bug, as indicated in the diagram on page 3 of this manual. Depending on the E-MAAX system, additional bugs can be added to provide the ability to monitor engine and alternator rpm, detect belt slippage, measure engine temperature, control voltage sensitive relays, auto-start auxiliary charging, and respond to a wide range of system conditions. As of the introduction of the E-MAAX system, there are 11 bugs available to customize and add functionality to your charge control system. Additional bugs are currently under development which will be available in Note: Installation instructions for individual bugs are provided in the bug packaging. The E-MAAX bugs and their features are listed below: 1. Battery Temperature Sensor Bug - The Battery Temperature Sensor Bug provides accurate temperature data to the CPU module, enabling the CPU to increase or decrease charging voltage based on ambient battery temperature as well as discontinuing charging completely if the battery bug senses that the batteries have exceeded safe working temperature (>125 F). 2. Alternator Temperature Sensor Bug - The Alternator Temperature Sensor Bug provides alternator temperature data to the CPU module, enabling the CPU to reduce the field pulse rate to lessen alternator load and reduce alternator temperature if a higher-than-optimal temperature is reached. 3. Engine Temperature Sensor Bug - The Engine Temperature Sensor Bug allows the CPU to monitor temperature at the engine block and delay alternator load until the engine has reached an optimal working temperature. If the Engine Temperature Sensor Bug is not installed, the CPU will revert to a standard timed delay. 4. Distribution (Branch) Bug - The Distribution Bug provides a single connection point between the CPU and five bugs. Distribution bugs can be chained to support as many individual bugs as are installed. 5. Communication Bug - The Communication Bug provides an RS232 serial port connection to the CPU, which allows the E-MAAX system to be hardwired to a laptop or desktop computer. 6. Buzzer Bug - The Buzzer Bug provides an audible signal if a system advisory message or malfunction is detected. 7. Output Bug - The Output Bug provides a source of switching that could be used to activate or deactivate a circuit based on system voltage or some other value within the system (temperature, etc.). An example would be controlling a solenoid that could automatically close when a given voltage is reached. 8. Input Bug - The Input Bug monitors a fuse or a switch and reports to the Remote Panel, via the CPU module, if a fuse or switch is open.

6 9. Belt/RPM Bug - The Belt/RPM Bug measures actual revolutions of engine and alternator pulleys, independently of alternator stator output, provides a relevant signal to the vessel s tachometer as well as the remote panel, and provides an advisory signal to the panel if the ratio between the alternator rpm and engine rpm deviates beyond an acceptable level (indicating belt slippage or damage. 10. Low Current Amp Bug - Provides precise measurement of low amperage currents (up to 30 amps peak/15 amps continuous) between charge source and batteries (eg., solar panels), or can be used to measure demand on specific load circuits. 11. High Current Amp Bug - Can be used to measure alternative charging or load currents (up to 150 amps peak/75 amps continuous) Example would be input current from wind generator. Remote Panel Operation The E-MAAX Remote Panel provides the user access to the charge controller s programming and operational functions, as well as real-time data regarding charging state, system temperatures, and battery condition. Access to operational data and programming modes is provided through five pushbuttons; UP, DOWN, PROGRAM, SAVE, and EXIT. A self-adjusting backlit 32-digit LCD display offers operational and programming information in bright, easy-to-read letters and numbers. Once installed, the Remote Panel remains in a sleep state. To awaken the panel, simply press any one of the control pushbuttons. Using the UP or DOWN buttons, the operator can scroll through operational display. If the UP or DOWN buttons remain untouched for 20 seconds, the Remote Panel will return to a sleep state. Data displayed will vary based on the sensor bugs installed. Basic data provided includes: E-MAAX Model Software Revision System Voltage Setting Battery Program Selected Charging Stage Charging Voltage Field Voltage Field Pulse Rate Field Management Percent Alternator Temperature Battery #1 Temperature Battery #2 Temperature Advisory Messages Accessing Program Mode In addition to operational data, the remote panel provides the ability to modify the charging functions of the CPU; system charging voltage, field polarity (P-type or N-type), battery program type, field output management, and a wide range of advanced programming functions.

7 The E-MAAX system s programming mode is accessed by pressing the PROGRAM button on the Remote Panel. The display will cycle to the Programming Mode. While in Programming Mode, the user can scroll through basic and advanced program settings. When a program change is selected, the change can be saved to memory by pressing the SAVE button. Once program changes are complete, the system can be returned to operational mode by pressing the EXIT button. Programming Modes Programming For System Voltage The first mode in the programming level display is System Voltage. Selections include 12 Volts DC or 24 Volts DC. The default voltage is 12VDC. Using the UP or DOWN buttons, change the voltage setting to match your system s voltage requirements. When the desired voltage value is displayed, press the SAVE button. The display will advance to the next programming mode. Programming For Field Polarity The next mode in the programming display is Field Polarity.Selections include Positive (for use with positively excited P-type alternators), or Negative (for use with N-type alternators which are excited on the alternator s negative brush). All Electromaax alternators are excited on the positive brush and will use the Positive setting. If a non-electromaax alternator is used, verify the field polarity of the alternator with its manufacturer. When the desired voltage value is displayed, press the SAVE button. The display will advance to the next programming mode. Programming For Battery Type The next programming mode establishes the charging program selected based on the type of battery being charged. E-MAAX Cruiser-series charge controllers offer programs for standard flooded, deep-cycle flooded, gel, AGM, thin plate pure lead and spiral-wound batteries in addition to a factory default program that s safe for all battery types. E-MAAX Voyager PRO-Series charge controllers add a special program specifically for the charging needs of lithium ion batteries. To select the battery program that matches your batteries, scroll through the program selections until you see the

8 program that best matches your system s battery technology by pressing the UP or DOWN buttons. When the display indicates the desired battery type, press the SAVE button. The CPU will save your program choice, and advance to the next programming mode. Note that you can exit the programming mode at any time by pressing the EXIT button. The display will return to operational mode and will sleep if no buttons are pressed for 20 seconds. Programming For Field Management Certain conditions may require that the user reduce the output or horsepower load of the alternator, such as limited engine horsepower or belt capacity. The Field Limiter function allows the user to adjust alternator load by controlling the maximum field output delivered to the alternator. A 100 percent Field Limiter display indicates no field. Field reduction is adjusted in 10 percent increments. To adjust the Field Limiter control, scroll up or down until the desired field reduction is displayed. Press the SAVE button when the desired value is displayed. Programming For 50% Output Rather than adjusting the Field Limiter mode, a quick 50 percent reduction in field output can be made by turning on or off the 50% Output mode. This is an excellent solution for instances where additional power is needed at the prop to deal with tidal current or other similar conditions. To adjust the 50% Output function, scroll up or down until the desired value is displayed. Press the SAVE button. Programming For Start Delay The E-MAAX charge controller can be equipped with a temperature sensor bug that will determine when the engine is sufficiently warmed up to handle the additional load of the alternator, or can be programmed for a time period that the regulator delays alternator excitation. The Start Delay program mode allows the user to set the duration of delay. Delay time is adjustable from no delay to 16 minutes of delay before ramping to charging voltage. To adjust the Start Delay, scroll up or down until the desired value is displayed. Press the SAVE button.

9 Advanced Programming Modes While the preset battery programs are satisfactory for the majority of charging conditions, the E-MAAX regulator features a number of advanced programming modes that allow modification of most charging functions. Advanced programming modes include: High Voltage Limit Low Voltage Limit Compensation Voltage Absorption # Voltage Absorption #1 Time Absorption #2 Voltage Absorption #2 Time High Voltage Limit High charging voltage setting enables the user to set the maximum allowable system voltage. If voltage exceeds the set limit, the regulator discontinues charging and activates an advisory message and alarm signal. Default voltage limit is 15.8 VDC / 31.6 VDC. Scroll UP or DOWN to select value. Press SAVE to save the program selection. Low Voltage Limit Low charging voltage setting enables the user to set the minimum allowable system voltage. If voltage drops below the set limit, the regulator activates an advisory message and alarm signal. Default voltage limit is 12.8 VDC / 25.6 VDC. Scroll UP or DOWN to select value. Press SAVE to save the program selection. Float Voltage Float Time Voltage Correction (Slope) Alternator Temp. Response Threshold Battery Temp. Response Threshold Equalization Voltage Setting Equalization Time Setting Compensation Voltage Controls the maximum allowable voltage above the battery type preset value for Absorption #1. Adjustment is in tenths of a volt. Scroll UP or DOWN to select value. Press SAVE to save the program selection. Absorption #1 Voltage Adjusts the Absorption #1 voltage of the selected battery preset program in tenths of a volt. Scroll UP or DOWN to select value. Press SAVE to save the program selection. Absorption #1 Time Adjusts the fixed time period the E-MAAX remains in the Absorption #1 stage of charge. Time is adjusted in tenths of an hour (six minutes). Default time is 30 minutes. Scroll UP or DOWN to select desired value. Press SAVE to save the program selection.

10 Absorption #2 Voltage Adjusts the Absorption #2 voltage of the selected battery preset program in tenths of a volt. Scroll UP or DOWN to select value. Press SAVE to save the program selection. Absorption #2 Time Adjusts the fixed time period the E-MAAX remains in the Absorption #2 stage of charge. Time is adjusted in tenths of an hour (six minutes). Default time is 30 minutes. Scroll UP or DOWN to select desired value. Press SAVE to save the program selection. Float Voltage Adjusts the Absorption #2 voltage of the selected battery preset program in tenths of a volt. Scroll UP or DOWN to select value. Press SAVE to save the program selection. Float Time Adjusts the fixed time period the E-MAAX remains in the Absorption #2 stage of charge. Time is adjusted in tenths of an hour (six minutes). Default time is 30 minutes. Scroll UP or DOWN to select desired value. Press SAVE to save the program selection. Voltage Correction (Slope) Enables the user to modify the calculation used by the CPU to determine the modification of charging voltage to compensate for changes in ambient battery temperature. Adjustment is in tenths of a volt. Scroll UP or DOWN to select desired value. Press SAVE to save the program selection. Alternator Temperature Response Determines the ambient alternator temperature that triggers field reduction. Default temperature response setting is 93 C. Adjustments are in 5 C increments. Scroll UP or DOWN to select desired value. Press SAVE to save the program selection. BATTERY Temperature Response Determines the ambient battery temperature that triggers field reduction. Default temperature response setting is 51 C. Adjustments are in 2 C increments. Scroll UP or DOWN to select desired value. Press SAVE to save the program selection.

11 Equalization Voltage Used to condition certain battery technologies, equalization voltage essentially overcharges batteries to eliminate sulfation and electrolyte stratification. Use only on batteries where recommended by the battery manufacturer. Adjustments range from.5 to 1.0 volt above Absorption #1 voltage. Scroll UP or DOWN to select desired value. Press SAVE to save the program selection. Equalization Time Provides control over the duration of the equalization/conditioning charge. Consult your battery manufacture for recommended equalization time and voltage. Equalization duration is set in 30 minute increments up to four hours. The equalization will occur as soon as the SAVE button is pressed after setting equalization voltage and time. The E-MAAX will return to your normal charge program when the equalization time duration is met. Scroll UP or DOWN to select desired value. Press SAVE to save the program selection. Charge Controller Operation The E-MAAX charge controller uses a multi-stage, voltage controllable charge profile to bring batteries to a fully charged state. Starting with a start time delay that can be controlled with a timer or an engine-block mounted temperature sensor, the E-MAAX ramps to a battery-safe selectable primary absorption period that brings the batteries from discharge to a nearly fully charged condition. Once the time and voltage values are met, and the field pulse rate required to maintain that voltage value drops below a given frequency, the E-MAAX enters a secondary absorption period. The secondary absorption period is engineered to continue to bring the batteries to a full charge. Once the conditions for a full charge are met, the E-MAAX drops to a maintenance/float voltage. If demands exceed the ability to keep batteries at a fully charged state in the float mode, the E-MAAX reverts to the secondary absorption state to ensure that loads and battery charging are met. Absorption #1 Absorption #2 Absorption #2 Soft Ramp Float Start Delay E-MAAX Voyager PRO Operation The E-MAAX Voyager PRO provides the user with the additional feature of current monitoring. Two built-in sensors allow the Voyager PRO to be connected with external shunts on the charging and load side of the batteries being charged. The ability to read charging and load current enables the Voyager

12 PRO to calculate actual battery condition by determining the amount of amperage being accepted by the batteries. This additional data can be used the the Voyager PRO to help determine optimal charging. In addition, the current data can be provided to the Remote Panel to allow the user to view the state of charge and alternator usage. This ability to consider current into and out of the batteries makes the Voyager PRO an ideal source of charge control for new technology lithium ion batteries, which require the charge source to shut down when the batteries reach a fully charged state.
