INTRODUCTION
The
Battery Isolator XR
is a fully electronic ‘master/kill switch’ system designed specifically for race
car applications. This device contains no moving parts and the solid construction provides very high resistance
to shock, vibration, water and dirt. Using the latest MOSFET technology this Battery Isolator provides safe,
spark-free isolation of the vehicle’s battery and engine electrics.
Meets FiA safety regulations.
PRINCIPLE OF OPERATION
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.
Alternator run-down protection is incorporated.
The electronic isolation circuits are controlled by a microprocessor and incorporate various safety systems
including over-temperature and over-current monitoring. The microprocessor also monitors the kill
switches/buttons for instant activation while eliminating false triggering. The unit will therefore instantly
trigger into isolation mode when any of the kill buttons are struck or on detection of any break in switch wiring
circuits such as during an accident.
The Isolator also incorporates an LED which displays status as well as fault codes.
