B7 FLASH It must be connected to B8 for the Flash memory
programming.
B8 FLASH It must be connected to B7 for the Flash memory
programming.
6.2 Connectors of the logic - Pump 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 Lifting potentiometer wiper.
A4 LIFT ENABLE Input for potentiometer lifting enable input; it is active
HIGH.
A5 SPEED1 Input for first speed request; it is 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 lifting potentiometer
A10 SPEED2 Input for second speed request; it is active HIGH.
A11 SAFETY IN If not connected to -Batt the AUX1 and AUX2 coil
power output will be disabled. It 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 SPEED3 Input for third speed request; it is active when
