6 DESCRIPTION OF THE CONNECTORS
6.1 Connectors of the logic - Traction configuration
A1 KEY Connected to the power supply through a microswitch
(CH) with a 10 A fuse in series.
A2 PPOT Potentiometer positive: 12 V / 5 V output; keep load >
1 kohm / 0.5 kohm.
A3 CPOT Accelerator potentiometer wiper.
A4 FORW Forward direction request input. It must be connected
to the forward direction microswitch, active high.
A5 REV Backward direction request input. It must be connected
to the backward direction microswitch, active high.
It can also be used as NPOT (potentiometer negative
reference) with the PEDAL WIRE KO diagnosis
implemented.
A6 SEAT SEAT input; it must be connected to the SEAT
microswitch; it is active when connected to -BATT.
A7 ENCA Incremental encoder phase A input.
A8 PENC Incremental encoder positive supply 12 V / 5 V
A9 -BATT Negative power supply. It is used as NPOT, without
PEDAL WIRE KO diagnosis, for acceleration
potentiometer and brake potentiometer
A10 CPOTBR Brake potentiometer wiper.
A11 SAFETY IN If not connected to -Batt the MC and EB coil power
output will be disabled. In the COMBI configuration it is
connected to SAFETY OUT (CNA#19) of pump
controller. This input can also be used as a general
purpose digital input.
A12 CAN-T If it is connected with A21 (CAN H) it introduces the
120 Ohm termination resistance between CAN-L and
CAN-H.
A13 SR/HB Speed reduction (handbrake) input. Active with switch
opened. Not active with switch closed to -Batt.
A14 ENCB Incremental encoder phase B input.
A15 ENC GND Encoder negative power supply.
A16 NLC Main contactor coil output. The coil is driven to
negative reference.
A17 PLC/PB Positive of the main contactor and electromechanical
brake coil.
A18 NEB Electro mechanic brake coil output. The coil is driven to
negative reference.
A19 SAFETY OUT It drives the external load to negative reference when
the REV input is active. It can be used for a flashing
light or acoustic indicator. The maximum current load is
1 A. In case of inductive load it is suggested to use a
free-wheeling diode across the load (with cathode
