6.1
Throttle Potentiometer
The throttle potentiometer is connected to P2-1, P2-2 and P2-3.
Both wig-wag (center off) and single-ended throttle configuration
can be used but you should ensure the controller is programmed
to the correct type, refer to the SP1 Programming and Fault
Finding Technical Manual and the controller data sheet.
The value of the potentiometer should be between 2k
Ω
and 10k
Ω
±
20%. If the full electrical span of the potentiometer is not used, a
throttle gain can be programmed such that full speed can be
achieved. Please refer to the SP1 Programming and Fault Finding
Technical Manual for details.
If the vehicle has a wig-wag (center off) throttle configuration it is
possible, by programming, to reverse the polarity of operation of
the throttle. For single ended throttles the polarity of operation of
the reverse switch can be selected, refer to the SP1 Programming
and Fault Finding Technical Manual.
6.1.1
Speed Limiting Potentiometer
A speed limiting potentiometer may be connected
between the throttle potentiometer wiper connection and
P2-3 of the controller. A resistance of 25 k
Ω
will limit the
speed to 30% of the maximum programmed speed. It is
possible to use a different value potentiometer and to
achieve different speed reductions, contact Penny & Giles
for details.
6.1.2
Alternative Throttle Inputs
Other factory programmed throttle inputs are available
such as a voltage input that accepts signals in the range of
0-5V or a unipolar wig-wag input using the reverse switch
to change direction. Please contact Penny & Giles for
details.

P2-4 provides the battery negative connection to the vehicle tiller.
