Battery Isolators

Introduction
The GT Battery Isolator from CARTEK is a very small and highly reliable alternative to the traditional mechanical master-switch and has been designed to overcome all of the problems and restrictions associated with mechanical and electro/mechanical safety cut-outs. When fitted to a race car our Solid State Battery Isolator simultaneously isolates the battery and kills the engine immediately when triggered in accordance with FiA safety regulations.
This system has been designed to simplify installation thereby saving time and reducing build costs.

Features
- Fully electronic with no moving parts
- Totally sealed against water and dirt
- Completely resistant to shock and vibration
- Fully integrated with built in alternator run-down circuitry - No extra components required
- Driver operation by a single internal ON-OFF button/switch
- External operation by single or multiple 'strike' button(s)
- Buttons / switches connected to Isolator using light weight wiring
- Mounts close to battery for reduced cabling
- Very small and weighs just 140g
- Designed and manufactured in UK using high quality components

How it Works
The Cartek Battery Isolator GT provides two functions. The first is to disconnect the Battery from all Electrical Circuits. The second is to kill the engine.

Battery Isolation 
The Battery Isolators work by being fitted in between the negative side of the battery and the chassis ( As seen above ). When the external kill button has been activated or the internal button been switched to the off state, then the Battery Isolator will disconnect the negative side of the battery from the Chassis. This means that no power can get to any of the electrical circuits as there is a break in the circuit.

Engine Kill
The Cartek Battery Isolator GT kills the engine by taking in a fixed 12v input and sending a 12v output that would power your Ignition or ECU. When the negative side of the battery has been disconnected it will also cut the 12v output powering your Ignition or ECU. This will kill the engine.

Built in Protection
The Cartek Battery Isolator GT comes with built in alternator run down protection meaning no extra wiring and no extra components.

How Is It Controlled?
The two electronic isolation circuits are controlled by microprocessors and incorporate various safety systems including over-temperature and over-current monitoring. These microprocessors also monitor the kill switches/buttons for instant activation without false triggering.

Description
All CARTEK Battery Isolators are designed to perform two functions in accordance with FiA motorsport safety regulations. These are:
1) Stop the Engine from running, 'Kill'.
2) Disconnect the Battery from ALL electrical systems, 'Isolate'.

The 'Engine Stop' function is implemented by disconnecting power to the ECU or Ignition circuit - forcing the engine to stop and electrical power generation by the alternator/generator to cease.
The 'Battery Isolation' function is implemented by disconnecting the negative side of the vehicle’s battery from chassis/ground, thereby disconnecting the battery from ALL of the car's electrical systems.
When activated, the Engine Stop function occurs a very short period of time before Battery Isolation. Alternator load dump protection is also built in so no additional components are needed.

User operation
All CARTEK Battery Isolators are operated using two switches: A dashboard mounted 'Internal Switch' allows the driver to turn the Battery Isolator ON and OFF. An 'External Switch' is for operation by safety personnel in an emergency situation. The Internal Switch can be used to turn the Battery Isolator ON and OFF, however the External Switch can only turn the Battery Isolator OFF. This is in accordance with Motorsport UK safety regulations.

All CARTEK Battery Isolators also shut down automatically if a fault is detected such as short-circuit, over-current, over-temperature or broken cable connections. If this happens then the LED on the Battery Isolator unit, and the CARTEK Internal Switch, will display a flash pattern to indicate the cause of the fault.

Introduction
The next generation of CARTEK Battery Isolator is now available.
The CARTEK Battery Isolator X-PRO is designed for all race and rally car applications. This Battery Isolator can handle high cranking current and so is suitable for large capacity and highly tuned race engines including V8s. It also features adjustable current limit for the Engine Stop Output signal and a 4 pin sealed DT connector for easy installation.

Key Features

- Configurable Engine Stop Output (5A/10A/15A/20A)
- Overcurrent + Overtemperature protection built in
- Integrated RGB status LED for diagnostic purposes
- Totally sealed against water and dirt
- Completely resistant to shock and vibration
