A10 GND This is the ground of the logic board.
A11 DI6 Input of the switch DI6. The input is activated when it is
connected to +Batt. The default function is the controller
“LOWER” enable input.
A12 DI8 Input of the switch DI8. The input is activated when it is
connected to +Batt. The default function is the controller
“1ST” input: the pump motor turn at a defined speed.
A13 DI10 Input of the switch DI10. The input is activated when it is
connected to +Batt. The default function is the controller
“2ND” input: the pump motor turn at a defined speed.
A14 DI12 Input of the switch DI12. The input is activated when the
external switch is opened to ground. The default function
is the controller “CUTBACK2” input, opening the switch
truck speed is reduced. In the Sense Coil version this
input is connected to the AC motor sense coil.
6.1.2 CNB external connector
B1 PEB This pin outputs the positive supply (equal to +Batt) of the
electromechanical brake coil. Depending on hardware
configuration this pin can be controlled by the
microcontroller or tied to the B2 input or to the C6 input.
See connection drawing for more details.
B2 PEV Connect the positive supply of all electrovalves (EV1,
EV2, EV3, LOWER EVP, HORN OUT) to this pin. Take
the positive supply immediately after main contactor.
B3 NEVP Output of the lower proportional electrovalve driver
(driving to –Batt). Built-in freewheeling diode to B2.
B4 DI3 Input of the switch DI3. The input is activated when it is
connected to +Batt. The default function is the controller
“FORWARD” request input, closing this input truck moves
in forward direction.
B5 NEB Electro mechanic brake coil driver output; PWM
controlled; 2.5A maximum continuous current (driving to –
Batt). Built-in freewheeling diode to B1.
B6 NLC Min Contactor coil driver output; PWM controlled; 1A
maximum continuous current (driving to –Batt). Built-in
freewheeling diode.
B7 HORN Negative of the protected horn electrovalve driver (driving
to –Batt). Built-in freewheeling diode to B2.
B8 DI4 Input of the switch DI4. The input is activated when it is
connected to +Batt. The default function is the controller
“REV” request input, closing this input truck moves in
backward direction.
6.1.3 CNC external connector
C1 +KEY Input of the key switch signal.
C2 DI1 Input of the switch DI1. The input is activated when it is
connected to +Batt. The default function is the controller
“BELLY” input, closing the switch quick inversion function
is activated.
C3 NPOT Potentiometers negative reference (GND).
