3.4 DESCRIPTION OF CONNECTORS
PIN NAME DESCRIPTION
A1 NEF Negative output of the electromechanical brake's coil (max. 3A).
A2 CPOT Potentiometer wiper (range: 0V (min) to 10V (max)).
A3 NPOT Negative potentiometer.
A4 PPOT Potentiometer positive: 12V output. Keep load >500W .
A5 PTG Positive of the main contactor's coil (max. 3A).
A6 NTG Negative of the main contactor's coil (max. 3A).
A7 RV2 Input for 2nd speed reduction request. If left free or connected to
battery negative the reduction function operates. If connected to A13,
the reduction is inhibited.
A8 RV1 Input for 1st speed reduction request. If left free or connected to
battery negative the reduction function operates. If connected to A13,
the reduction is inhibited. This speed reduction is linked to an adjust-
able braking (curve braking).
A9 MA Forward direction microswitch. It should be connected to the forward
microswitch, active HIGH (+VB).
A10 MI Backward direction microswitch. It should be connected to the back-
ward microswitch, active HIGH (+VB).
A11 TIM/SEAT It should be connected to the tiller microswitch or to the seat
microswitches (2 sec delay). It is active high (+VB).
A12 IR Quick inversion input, it is active HIGH (+VB).
A13 CMM Common IR/TIM/MI/MA/RV1/RV2 microswitch (+VB).
A14 CH Connected to the power supply through a 6.3A fuse and the key-
switch.
