Connector B
B1 PEV Connect the positive supply of electrovalves (EV1, EV2,
EV3, EV4, EV5) to this pin. Take the positive supply
immediately after the main contactor.
B2 CPOT EVP Proportional-valve-potentiometer input (wiper contact).
B3 ANIN5 Free analog input.
B4 AUX1 Free digital input, active when connected to -Batt
B5 AUX2 Free digital input, active when connected to -Batt.
B6 BACKING FW Forward-inching-request input. It must be connected to
the forward-inching microswitch, active high.
B7 SH1/SIN First Hall-sensor input, active low. Using a special
hardware configuration it is possible to use it for the sin
signal of a sin/cos sensor.
B8 PSENS Positive supply 12 V / 5 V for Hall sensors or sin/cos
sensor.
B9 NEV5 Output for the voltage-controlled PWM-modulated EV5
electrovalve; 1 A maximum continuous current (driving to
-Batt). Freewheeling diode to B1 is built-in.
B10 STEER POT Steering-potentiometer input (from wiper contact).
B11 AUX3 Braking-request input. It must be connected to the brake
pedal microswitch, active high.
B12 CAN_T2 CAN termination. If it is connected to B21 (CAN_H2) it
introduces the 120 Ohm termination resistance between
CAN_L2 and CAN_H2.
B13 BACKING BW Backward-inching-request input. It must be connected to
the backward-inching microswitch, active high.
B14 SH2/COS Second Hall-sensor input, active low. Using a special
hardware configuration it is possible to use it for the cos
signal of a sin/cos sensor.
B15 NSENS Negative supply for Hall sensors (or sin/cos sensor).
B16 NEV1 Output for the voltage-controlled PWM-modulated EV1
electrovalve; 1 A maximum continuous current (driving to
-Batt). Freewheeling diode to B1 is built-in.
B17 NEV2 Output for the voltage-controlled PWM-modulated EV2
electrovalve; 1 A maximum continuous current (driving to
-Batt). Freewheeling diode to B1 is built-in.
B18 NEV3 Output for the voltage-controlled PWM-modulated EV3
electrovalve; 1 A maximum continuous current (driving to
-Batt). Freewheeling diode to B1 is built-in.
B19 NEV4 Output for the voltage-controlled PWM-modulated EV4
electrovalve; 1 A maximum continuous current (driving to
-Batt). Freewheeling diode to B1 is built-in.
B20 CAN_L2 CAN bus 2 low-level signal.
B21 CAN_H2 CAN bus 2 high-level signal.
B22 SH3 Third Hall-sensor input, active low.
B23 FREE Free pin.
