4.9 TESTER: DESCRIPTION OF THE FUNCTION; STANDARD VERSION
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. The following definition listing shows the relative measure-
ments :
1) BATTERY VOLTAGE: level of battery voltage measured at the input to the key
switch.
2) MOTOR VOLTAGE: this is the voltage supplied to the motor by the inverter; it is
expressed as a percentage of the full voltage (which depends of the battery voltage).
3) VOLTAGE BOOSTER: this is the booster of the voltage supplied to the motor in
load condition; it is expressed in a percentage of the full voltage.
4) FREQUENCY: this is the frequency of the voltage and current supplied to the motor.
5) ENCODER: this is the speed of the motor, expressed in the same unit of the fre-
quency; this information comes from the speed sensor.
6) 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.
7) COS FI: this is the cos ϕ (real time calculated) of the motor.
8) CURRENT RMS: Root Mean Square value of the motor current.
9) BATTERY CURRENT: this is the battery current (not measured but calculated).
10) BATTERY CHARGE: the percentage Charge level of the battery.
11) TEMPERATURE: the temperature measured on the aluminum heat sink holding the
MOSFET devices.
12) 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.
13) BRAKE PEDAL POT: the voltage of the brake pedal potentiometer's wiper
(CPOTB). 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.
14) LIFTING SWITCH: the level of the "Lifting switch" digital entry.
ON / +VB = active entry of closed switch.
OFF / GND = non active entry of open switch.
15) DESCENT SWITCH: the level of the "Descent switch" digital entry.
ON / +VB = active entry of closed switch.
OFF / GND = non active entry of open switch.
16) FORWARD SWITCH: the level of the Forward direction digital entry FW.
ON / +VB = active entry of closed switch.
OFF / GND = non active entry of open switch.
17) BACKWARD SWITCH: the level of the Reverse direction digital entry BW.
ON / +VB = active entry of closed switch.
OFF / GND = non active entry of open switch.
