NOTES ON ELECTRONIC EXCHANGE
mod.P5
DIFFERENCES FROM THE EARLIER VERSION:
1. The new exchange has 3 relays, instead of one as in the earlier version;
2. The orange wire connected to the microswitch on the brake shaft (for safety
when braking) needs an original earth (e.g. the battery earth; never connect it to
screws or bolts in the coachwork); there is no longer any need for connection to a
+12V positive (earlier version).

3. The working of the motor reducer is anticipated, while the contact of the servo
clutch is delayed and no longer happens at the same time like in the earlier
version; this function can be regulated with potentiometer P5;
4. In the earlier version the sensitivity of the circular potentiometer of the ring was
regulated by potentiometer P2 and the activation of the motor reducer and clutch
contact was therefore controlled by the same relay and potentiometer P2.
These two functions have been separated in the new exchange:
· the motor reducer is regulated by a relay and by potentiometer P2;
· the clutch contact is regulated by a relay and by potentiometer P5.
5. If the accelerator is combined with a servo clutch, use the brown and black wires
of the grey cable to change the contact on the accelerator pedal. The start of the
first stroke of the clutch can be anticipated or delayed by potentiometer P5,
depending on the acceleration desired.
