All race and rally master switches must perform two functions, (1) disconnect the battery from all electrical circuits and (2) kill the engine. The Battery Isolator XR performs the battery disconnection function by breaking the connection between the NEGATIVE battery terminal and CHASSIS/EARTH. The Battery Isolator XR performs the engine kill function by outputting a signal which can be used to enable/disable ECUs or PDMs or used to control an engine relay.
SPECIFICATION Typical installation BODY ELECTRICAL SYSTEMS. ALTERNATOR. STARTER MOTOR. CAR BATTERY ENGINE KILL SIGNAL TO ECU, PDM or ENGINE RELAY. START BATTERY (Optional) INTERNAL ON/OFF BUTTON (2 wires) CHASSIS MOUNTED CLOSE TO BATTERY. EXTERNAL KILL BUTTON (Now with chassis connection) Technical Details Size: L = 60mm, W = 45mm.
THIS PRODUCT IS DESIGNED FOR MOTORSPORT USE ONLY AND SHOULD NOT BE USED ON ROAD/STREET VEHICLES OR ON PUBLIC HIGHWAYS. NO WARRANTY IS MADE OR IMPLIED REGARDING ANY CARTEK PRODUCTS TO PROTECT USERS FROM INJURY OR DEATH. USER ASSUMES ALL RISKS.
INSTALLATION Step 2. FITTING The Battery Isolator should be mounted directly to the vehicle’s metal chassis close to the vehicle’s battery but away from any high temperature sources. The Battery Isolator should be mounted securely with unpainted screws/bolts to provide good electrical contact with the chassis.
INSTALLATION Step 2. SWITCH CONNECTIONS The Isolator can be controlled by any number of on-off/kill switches although the usual configuration is one internal on-off button and one external kill button. The internal switch needs to be of a latching type, either toggle or pushbutton, such that the ON position makes the circuit while the OFF position breaks the circuit.
INSTALLATION Step 3. ENGINE KILL CONNECTION For cars equipped with an alternator, the Battery Isolator needs to kill the engine by sending a signal to the engine ECU or electronic Power Distribution Module (PDM) or by shutting down the main engine relay. The engine kill output signal has two states: Battery Isolator ON - 12V (0.5A max).
INSTALLATION Step 4. FINAL CONNECTION Once Steps 1,2 & 3 are completed a final connection should be made from the negative terminal of the vehicle battery to the Battery Isolator terminal marked BATTERY NEGATIVE. This connection should be made with cable of 100-200Amp capacity and by keeping as short as possible will offer maximum weight saving of the complete installation.
FAULT DIAGNOSIS FAULT DIAGNOSIS Once fully installed, the Isolator is switched ON by activating the internal ON-OFF switch/button. On activation the Isolator performs a system check before electrical power is switched on. If any fault is detected then the Isolator will remain in the OFF state and display the fault status via the LED in a sequence of flashes: 1 flash - External Kill Button pressed or External Kill Button circuit broken.
