Master Control - "Dualac2 Power 80V"
SUBMENU "SET OPTIONS"
1. HOUR COUNTER
RUNNING: the counter registers any motor running.
SEAT: the counter registers when the "key" is closed and operator is sitting on the seat.
2. BATTERY CHECK
ON: the battery discharge level check is carried out; when the battery level reaches 10%, a fault is sig-
naled (-66 code) and the maximum current is reduced to half th programmed value.
OFF: the battery discharge level is carried out but no fault is signaled.
3. HYDRO ON
ON/OFF Controller manages the power steering function when the "key" is switched on.
4. STOP ON RAMP
ON the stop on ramp feature (truck electrically held on a ramp) is managed for a time established by "
auxiliary time" parameter.
OFF the stop on ramp feature is not performed.
5. AUX INPUT #1
EXCLUSIVE
HYDRO:
input C10 activates power steering function, output A31 is activated.
OPTION #1 input C10 is the input for the handbrake switch, active low (open switch)
OPTION #2 input C10 is input for a speed reduction switch, active low (open switch)
6. PEDAL BRAKING
ANALOG: The mechanical brake pedal has a switch and potentiometer installed. When the accelerator is
released and the pedal brake is pushed the controller performs an electrical braking whose intensity
is proportional to the brake pedal potentiometer. The minimum intensity is established by the
"Release braking" parameter, when the brake pedal is slightly pressed (brake switch closed but
brake potentiometer at minimum). The maximum intensity is established by the "Pedal Braking"
parameter, when the brake pedal is fully pressed (brake potentiometer at maximum). In the middle
positions, the electrical braking intensity is a linear function between minimum and maximum
intensity.
Digital: The truck does not have a potentiometer installed on the mechanical brake pedal, but only a micro
switch; when the accelerator is released and the brake pedal is pushed (brake switch closed), the
controller performs an electrical braking following "Pedal Braking" parameter.
7. SET TEMPERATURE
DIGITAL: A digital (ON/OFF) motor thermal sensor is connected C25 (C35) input.
ANALOG: An analog motor thermal sensor is connected to C25 (C35) (the curve can be customized on cus-
tomer request).
None No motor sensor switch connected.
8. STEER TABLE This parameter is used to set the correct steering table.
8. MODE SELEC-
TION
Used to set up the working mode of truck. (0=Economy, 1=Normal, 2=Power, 3=Turtle mode)
