4.2.3 ACE3 Traction Premium
Connector A
A1
KEY
Connected to the power supply through a microswitch in
series to a 10 A fuse.
A2
PANIN
Positive supply for potentiometers: 12 V / 5 V output; keep
load impedance > 1 kOhm / 0.5 kOhm.
A3
CPOT
Accelerator-potentiometer input (from wiper contact).
A4
FW
Forward-request input. It must be connected to the
forward-drive microswitch, active high.
A5
BW
Backward-request input. It must be connected to the
backward-drive microswitch, active high.
A6
SEAT
Seat input. It must be connected to the seat microswitch,
active to -Batt.
A7
CHA
Incremental-encoder phase-A input.
A8
PENC
Positive supply 12 V / 5 V for encoder.
A9
AGND
Negative supply for potentiometers.
A10
CPOT BR
Brake-potentiometer input (from wiper contact).
A11
PB/QI
Pedal-Brake/Quick-Inversion input, active high.
A12
CAN_T1
CAN termination. If it is connected with A21 (CAN_H1) it
introduces the 120 Ohm termination resistance between
CAN_L1 and CAN_H1.
A13
SR/HB
Speed-reduction-request or handbrake-request input.
Active when the microswitch is open, inactive when it is
closed to -Batt.
A14
CHB
Incremental-encoder phase-B input.
A15
NENC
Negative supply for encoder.
A16
NLC
Main-contactor output. The coil is driven to -Batt.
Freewheeling diode to the positive supply is built-in.
A17
PEB
Connect the positive supply of electrovalves (EB and
EVP) to this pin. Take the positive supply immediately
after the main contactor.
A18
NEB
Electromechanical-brake output. The coil is driven to
-Batt. Freewheeling diode to A17 is built-in.
A19
NEVP
Proportional-electrovalve output. The coil is driven to
-Batt. Freewheeling diode to A17 is built-in.
A20
CAN_L1
CAN bus 1 low-level signal.
A21
CAN_H1
CAN bus 1 high-level signal.
A22
NCAN
CAN bus negative supply.
A23
PTH
Motor-temperature-sensor input. It is possible to use a
digital or analog (PTC) sensor.
