ACCELERATOR POTENTIOMETER ADJUSTMENT
1. Check the ON/OFF condition of the switch
1.1. SW8 (single pedal)
1.2. SW4 - SW5 (double pedal)
2. Adjustment of Accelerator Potentiometer (P2)
Installation
(1) Before installing a new traction potentiometer it is
suggest to check it with an analogue multimeter.
Move slowly the wiper until the maximum stroke and
in the same time check if the multimeter increases
or decreases the value proportionally with the
movement.
(2) Install the potentiometer and connect it to the wiring
loom of the machine.
(3) After closing the microswitch the voltage on the
wiper of the potentiometer has to be approximately
1.6V and 3.2V to the maximum stroke. This
measure is referred to its negative.
(4) Once the potentiometer is set, carry out the traction
potentiometer acquisition (see chapter 3: Display).
(5) After adjusting the switch ON/OFF operation, apply
yellow paint to the head of a set screw.
