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

BATT AUX VOLTAGE

Displays the current battery voltage at the speed controller.

TEMPERATURE (SAME AS HEATSINK IN IQ SYSTEM)

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: Anything that adds resistance (i.e. improper brake adjustment, low air pressure in tires, low battery voltage,
etc.) can 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).

ARMATURE 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.

BRAKE VOLTS IN

This menu is reserved for possible future use and has no application at this time.

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 indicate that
speed pulses are off. When the vehicle is gently pushed a short distance, the handset should indicate that speed
pulses are on.
