The following faults can be detected by the IQ System controller:
HW FAILSAFE
The armature drive FET’s (field effect transistors) regulate the armature current. If the speed controller
detects a failure of the armature drive FET’s or circuitry, a
hardware failsafe fault is detected.
THROTTLE FAULT 1
If the MCOR (Motor Controller Output Regulator) voltage is less than 0.20 volts or greater than 4.80 volts, the
controller detects a
throttle fault .
SPEED SENSOR
If the speed controller does not detect pulses from the speed sensor while the controller outputs power
(greater than 75% armature PWM) to the motor, a
speed sensor fault is detected.
MAIN WELDED
If the speed controller detects that the solenoid contacts are welded closed, a main welded fault is detected.
MAIN DRIVER ON
If the FET that controls the closing of the solenoid contacts is found to be energized when it should not be, a
main driver on fault is detected by the speed controller.
