15) Set “MAX SPEED BACK” (Reverse).
16) Make the choice for the truck behaviour on a slope (see chapter 5.4). If the "Stop on
ramp" option is ON, set the desired value of "auxiliary time" parameter.
5.8 TESTER: DESCRIPTION OF THE FUNCTION
The most important input or output signals can be measured in real time using the TE-
STER function of the console. The Console acts as a multimeter able to read voltage,
current and temperature. In the following chapter a list of relative measurements for differ-
ent configurations.
5.8.1 "Dualac2" and "Dualac2 Power" - Master
1) MOTOR VOLTAGE: this is the voltage supplied to the motor by the inverter; it is ex-
pressed as a percentage of the full voltage (which depends of the battery voltage).
2) FREQUENCY: this is the frequency of the voltage and current supplied to the motor.
3) ENCODER: this is the speed of the motor, expressed in the same unit of the fre-
quency; this information comes from the speed sensor.
4) SLIP VALUE: this is the difference of speed between the rotating field and the shaft
of the motor, expressed in the same unit of the frequency.
5) CURRENT RMS: Root Mean Square value of the motor current.
6) TEMPERATURE: the temperature measured on the aluminum heat sink holding the
MOSFET devices.
7) TEMPERATURE #1: this is the temperature of the right motor; if the option is pro-
grammed "None" (see chapter 5.4.a) it shows 0°.
8) TEMPERATURE #2: this is the temperature of the left motor; if the option is pro-
grammed "None" (see chapter 5.4.a) it shows 0°.
9) ACCELERATOR: the voltage of the accelerator potentiometer's wiper (CPOT). The
voltage level is shown on the Left Hand Side of the Console Display and the value in
percentage is shown on the Right Hand Side.
10) STEER ANGLE: this is the indication of the angular position of the steered wheel.
11) BRAKE PEDAL POTI: voltage of the brake potentiometer's wiper (CPOTB). The
parameter is active only if the PEDAL BRAKING parameter is set ANALOG (see
chapter 5.4.).
12) INTERNAL WHEEL CUTBACK: this is the indication of the speed reduction applied
to the internal wheel; in other words, it shows the ratio of the two speeds.
13) SEAT SWITCH: the level of the Seat Microswitch digital input.
ON / +VB = input active, switch closed.
OFF / GND = input non active, switch open.
14) FORWARD SWITCH: the level of the Forward direction digital input FW.
ON / +VB = input active, switch closed.
OFF / GND = input non active, switch open.
