IQ DISPLAY MODULE (IQDM) AND IQDM-P
DIAGNOSTICS: IQ SYSTEM

BATT VOLTAGE

Displays the current battery voltage at the speed controller.

HEATSINK

Displays the temperature (in degrees Celsius) of the speed controller heatsink. During normal operating conditions, the
heatsink temperature should be below 85 °C ±5 °C (185 °F ±9 °F). See following NOTE.
NOTE: Improper brake adjustment can sometimes cause the operating current to be higher than normal. This higher
current increases the temperature of the speed controller heatsink.

ARM CURRENT

Displays the motor armature current (in amperes).

FIELD CURRENT

Displays the motor field current (in amperes).

ARM PWM

Displays motor armature PWM (pulse width modulation). The range of pulse width modulation is 0% to 100%. When
the vehicle is operating at full speed, the pulse width modulation should be at 100%.

FIELD PWM

Displays motor field PWM (pulse width modulation). The range of pulse width modulation is 0% to 100%. When the
vehicle is in operation, the pulse width modulation will fluctuate in response to the terrain and throttle input.

SPEED PULSES

The speed pulses menu item displays the activity of the motor speed sensor. With the key switch in the OFF
position, the Forward/Reverse switch in the NEUTRAL position, and the vehicle at rest, the handset should should
indicate that speed pulses are off. When the vehicle is gently pushed a short distance, the handset should indicate
that speed pulses are on.

FOOT INPUT

Indicates the status of the throttle position sensor or MCOR(motor controller output regulator) internal limit switch:
on or off. When the accelerator pedal is unpressed, the handset should indicate that the limit switch is off. When
the accelerator pedal is pressed and the key switch is in the ON position, the display should indicate that the limit
switch is on.
