What to connect
From digital switch
input 4.
In a basic configuration
this is usually the seat
switch.
From digital switch
input 7.
From a thermistor
device mounted inside
the motor
Supply feed to
potentiometer 1. In a
basic configuration this
is the throttle.

Type A
See note to Table 3
V = Vb
See Table 3
Type B
See note to Table 3
V = Vb
See Table 3
V = 5 V
A NTC thermistor having a
(via 2.2 kΩ
resistance of approximately
2.2 kΩ at 100°C will give
internal pull-
up resistor)
best sensitivity.
Connect the other lead of
the thermistor to the B-
terminal of the Gen4
controller.
Can also be used as an
additional analogue input

Suitable for potentiometers
in the range 500 Ω to 10 kΩ
I = 15 mA
V = 10 V
Suitable for potentiometers
in the range 500 Ω to 10 kΩ.
