|
The E-MAAX CSR ensures the alternator, whether a generic alternator or one of Electromaax’s high output alternators, provides the optimum charge profile to satisfy the various battery technologies and the current operating conditions. The E-MAAX CSR by continually monitors system voltage achieves this goal.
The control algorithms and a high-speed communication network ensure fast, accurate response to any of the charge / load conditions experienced in a marine application. The rapid response capability ensures any transient electrical events, even under the most extreme situations, are handled effectively with a fail-safe action.
The supplied USI interface (Com Module required) brings all available performance parameters to a single PC screen. Additional available temperature sensors collect real-time operating data allowing the owners to evaluate “at a glance” their vessel’s charging system. The same interface allows factory-based diagnostics through E-MAAX Remote technical support. You can upgrade to the E-MAAX PRO or PLUS at any time without any alterations to the systems hardware. |

System Components
|
The basic CSR system is comprised of 2 components:
CSR Regulator Module:
CSR Regulator Module is a durable plastic enclosure 15×10 cm features 5 connection ports; the first connection port is a 6 pin power connection. Any of the other four 4-pin connection ports will accept the various accessory devices. The face surface of the enclosure has 2 multi-color LEDs, used for status indication. CSR Regulator Module controls alternator output via Field output, and utilizes micro-processor based communications to monitor battery and alternator temperatures. The CSR is factory programmed specific to the end-users system, that is: - System voltage ( 12 or 24)
- Battery Technology ( Lead acid / AGM / GEL / Carbon Foam)
- Alternator configuration (P or N)
Power Cable:
The 2-meter Power Cable is a 4-wire connection cable which plugs into the CSR module via the 6-pin quick-connector.
Wire color codes:
- Black = Battery Ground
- Red = Battery Positive
- White = Ignition (keyed)
- Brown = Field Output
Refer to the wiring schematics below for additional connection information.

Supported Peripherals
The CSR Regulator Module and the Power Cable are a complete functioning charge control system; however, additional accessory peripherals are available to enhance capability and provide additional system operating control and diagnostics. All accessories use the standard 4-pin connector, allowing simple connection to the CSR module.
Com Module (CM):
Provides both a USB based display interface and a Field Reduction Switch for limiting alternator output to 50%. The CM is typically mounted in the “Nav Station” allowing computer connection via the 1m (3ft) supplied USB cable. Connection to the CSR is via any of the 4-pin ports.
The operating parameters can be remotely displayed into a PC Laptop via the Com Module. The following data will be displayed:
- System Voltage
- Regulator Temperature
- Battery Temperature (sensor required)
- Alternator Temperature (sensor required)
- Field Output %
- Ignition Status
- Field Reduction Switch Status (sensor required)
- Critical Fault Status
- Setting Fault Status
|

Temperature sensors:
The battery and alternator temperature sensors are colored coded (Black=Battery / Silver=Alternator). Provided with the standard 3 meter (10 ft.), extension cables can be purchased if required for additional length. The sensor end has the electronics encapsulated into the aluminum housing ready for mounting via the 8 mm (5/16”) hole. The face side of the sensor has a status indicating LED. The connection end is the 4-pin moisture tight connector for the module. Refer to the Temperature Sensor Datasheet for additional information regarding functionality. |

Installation
|
|
The CSR Regulator has been designed with marine environment and the boater in mind. The CSR is a compact, module system requiring minimal tools and spatial requirements, the system can be easily installed by a DIY boater. The module is secured using 2 screws; allow room for access to the connection ports along the lower edge.
Refer to CSR Regulator Datasheet for wiring connection information.
Various available peripherals allow for system enhancement with simple “Plug and Play” convenience. All connectors for the CSR regulator allow only a single orientation position connection, note when inserting. |

Order of actions: - Mount the regulator in a suitable location close to the engine and battery using two M6 or 1⁄4” screws. Plug the Power cable into the CSR regulator.
- If an Alternator Temperature Sensor is included in the package, mount it the on a suitable location on the alternator case, so the sensor’s LED indicator is visible. Good temperature transfer should be provided between the alternator case and the sensor. Connect sensor’s cable to any available port of the CSR regulator.
- If a Battery Temperature Sensor is included in the package, mount it onto the battery either to a stud or directly to the battery housing so the sensor’s indicator is visible. Good temperature transfer must be provided between the battery and the sensor. Connect sensor’s cable to any available port of the CSR regulator.
- If the optional Com Module has been purchased, mount it in a suitable location such as the “Nav Station” to allow connection to a PC via the 1m USB cable. Connect the 4-pin plug to any available port of the CSR regulator (extension cable available if required).
- The Power Cable consists of 4 wires, (Black / Red / White / Brown) requiring the following connections;
- Black – The primary ground connection on the alternator or bus-bar.
- Red – The primary positive connection on the alternator ( B+ post)
- White – The switched side of the ignition switch. Ensure voltage is present only when the ignition switch is “ON” (first position).
- Brown – Field input of the alternator.
- The Power cable is connected to the CSR regulator via the 6-pin connector in the 6-pin port (see schematic below)
Once the CSR system is installed and connected, the boat electrics can be enabled. Visual status and diagnostics are provided via the LED indicators. |

Fault Diagnostics
|
|
The CSR module is programmed to detect and display various system alarm states, with a corresponding mitigating action. The specific alarm is defined by the LED indicators.
Refer to the CSR Regulator Datasheet for information regarding reading the alarm state, the corresponding CSR action and required remedy.
The following information regarding alarm states is taken from the CSR Regulator Datasheet;
Half Field condition:
Half Field condition is a special mode of regulation when the Field Output is reduced to 50% of its nominal value for the current charging conditions. The regulator is placed into the Half Field condition due to one or more of the following conditions:
- The battery’s temperature reaches 40°C (if equipped)
- The alternator’s temperature is reaches 90°C (if equipped)
- The regulator’s temperature reaches 60 ° C
- The Field Reduction Switch (FRS) in the Com Module is enabled (if equipped)
The Half Field condition is indicated by the right LED flashing red once per second. Half Field condition is re-set automatically when the following situations occur;
- ignition is switched off
- alarm condition is cleared
- manually via Field Reduction Switch (FRS) if equipped and enabled
Critical Fault condition:
Critical Fault condition is an alarm mode (right LED flashing red two times quickly) when Field output is restricted to 10% in order to avoid damage to the charging system. The regulator is placed into the Critical Fault condition due to one or more of the following conditions:
- The battery’s temperature reached 50°C (if equipped)
- The alternator’s temperature reaches 100°C (if equipped)
- The regulator’s temperature has exceeded the 90° C
- In-line fuse on the power supply line is blown
Critical Fault condition does not require restart of the regulator; it is re-set automatically when the fault condition is cleared.
Settings Fault condition:
Settings Fault condition is an alarm mode (periodically flashes red three times) when no Field output is supplied to the alternator in order to avoid damage to the charging system. The regulator is placed into the Settings Fault condition due to one or more of the following conditions:
- The regulator has not been configured by Electromaax
- The regulator is configured for a 12-Volt system and a 24-Volt system has been detected
- The regulator is configured for a 24-Volt system and a 12-Volt system has been detected
To clear the Settings Field condition requires the trigger condition to be eliminated and the restart of the regulator. |
