7. RF relay (option)
(1) Activates the forward travel buzzer.
(2) When the F/R lever is placed in the F
position, the battery supplies voltage to the
CN1D-33 terminal. This activates the relay,
feeding power to the forward travel buzzer.

8. Drive motor rotation sensor
(1) Detects the drive motor speed.
(2) When the drive motor runs, a pulsed
voltage is present between CN2D-3 and
CN2D-15 and between CN2D-5 and
CN2D-16.

9. Drive motor thermosensor
(1) Detects the drive motor temperature.
(2) When the sensor detects a temperature of
145°C [293°F] or above, the symbol
206 appears on the LCD panel, the
blinks, and the motor output is limited.
(3) When the sensor detects a temperature
of 156°C [312.9°F] or above, the symbol
205 appears on the LCD panel, the
blinks, and the motor is stopped.
