8.4 Function configuration
8.4.1 "Dualac2" and "Dualac2 Power" - Master
Using the CONFIG MENU of the programming console, the user can configure
the following functions (see "OPERATIONAL FEATURE" chapter for an
explanation of "hydraulic steering function"):
SUBMENU "SET OPTIONS"
1) HOUR COUNTER
- RUNNING: the counter registers travel time only.
- KEY ON: the counter registers when the "key" switch is closed.
2) BATTERY CHECK
- ON: the battery discharge level check is carried out; when the battery
level reaches 10%, an alarm is signalled and the maximum current is
reduced to the half of the programmed value.
- OFF: the battery discharge level check is carried out but no alarm is
signalled.
3) TRACTION CUTOUT
- ON / OFF: when the “Battery low” alarm appears, if this option is
programmed ON the traction speed is reduced to 60 Hz.
4) HYDRO KEY ON
- ON / OFF: if this option is programmed ON the traction inverter
manages an hydraulic steering function when the "key" is switched ON.
5) STOP ON RAMP
- ON: the stop on ramp feature (truck electrically hold on a ramp) is
managed for a time established by "auxiliary time" parameter.
- OFF: the stop on ramp feature is not performed.
6) AUX INPUT #1
- EXCLUSIVE HYDRO: input C10 activates hydraulic steering function,
output C31 is activated.
- OPTION #1: input C10 is the input for an handbrake device, active
low (open switch).
- OPTION #2: input C10 is the input for a speed reduction device,
active low (open switch).
7) PEDAL BRAKING
- ANALOG: the mechanical brake pedal has a switch and a
potentiometer installed. When the accelerator is released and the pedal
brake is pushed the inverter 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 close but brake
potentiometer at the minimum). The maximum intensity is established by
the "Pedal braking" parameter when the brake pedal is fully pressed
(brake potentiometer at the 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 microswitch; when the accelerator
pedal is released and the brake pedal is pushed (brake switch closed),
the inverter performs an electrical braking following "Pedal braking"
parameter.
