SAFETY WARNINGS:
- All automobiles wired with the ISIS™ Intelligent Multiplex System™ must have a neutral safety switch. (See application instructions for more details)
- If the automobile’s battery does not have a charge between 10V and 14V ISIS™ Intelligent Multiplex System™ will not turn on.
- Also, if the alternator is fluctuating, ISIS™ Intelligent Multiplex System™ will also turn off. This will turn off the car.
- If you apply battery power to ISIS™ and a switch is in the “on” position, ISIS™ Intelligent Multiplex System™ will block that function to prevent injuries. inSIGHT™ diagnostic module will read “Function in Abnormal Logical State. Function Blocked”. To unblock the function simply remove power, place the switch in the “off” position, and re-apply power.
- If the temperature of one of the boards exceeds 125°C, ISIS™ Intelligent Multiplex System™ will turn off to prevent damage. To turn the system back on, let the car cool down and cycle the power.
