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 ANIN3 Free analog input.
B3 ANIN5 Free analog input.
B4 3RD Third-speed input, to be connected to the 3
rd
-speed
microswitch, active high.
B5 4TH Fourth-speed input, to be connected to the 4
th
-speed
microswitch, active high.
B6 2ND Second-speed input, to be connected to the 2
nd
-speed
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 ANIN5 Free analog input.
B11 5TH Fifth-speed input, to be connected to the 5
th
-speed
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 1ST First-speed input, to be connected to the 1
st
-speed
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.
