4.2.2 ACE3 Pump Standard
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 Lift-potentiometer input (from wiper contact).
A4 LIFT Lifting-request input. It must be connected to the
lifting-enable microswitch, active high.
A5 LOWER Lowering-request input. It must be connected to the
lowering-enable 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 the lifting potentiometer.
A10 ANIN2 Free analog input.
A11 HYDRO Hydraulic-steering request 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 Speed-reduction request input. Active when the switch is
open. Not active 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 PAUX Connect the positive supply of electrovalves (AUX and
EVP) to this pin. Take the positive supply immediately
after the main contactor.
A18 NAUX Auxiliary-coil output. The coil is driven to -Batt.
Freewheeling diode to A17 is built-in.
A19 NEVP Lowering-proportional-electrovalve output. The coil is
driven to the negative reference. 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 PTHERM Motor-temperature-sensor input. It is possible to use a
digital or analog (PTC) sensor.
