TESTER MENU
The most important input or output signals can be measured in real time using the TESTER function of the handset. The
handset acts as a multimeter able to read voltage, current and temperature. The following is a list of measurements for
different configurations.
Handset Tester: user can verify the state of the following parameters:
SLAVE CONTROL
Slave Control - "Dualac2 Power 80V"
Motor voltage (%) Current RMS (A) Back switch (ON/OFF)
Frequency (Hz) Temperature (°C) Enable switch (ON/OFF)
Encoder (Hz) Seat switch (ON/OFF) Voltage booster (%)
Slip Value (Hz) Forw switch (ON/OFF) Battery voltage (V)
1) MOTOR VOLTAGE: This is the voltage supplied to the motor by the controller; it is expressed as a percentage
of full 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 frequency; this informa-
tion 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) SEAT SWITCH: The level of seat microswitch digital input.
ON /+BV = input active, switch closed.
OFF / GND = input non-active, switch open.
8) FORWARD SWITCH: The level of the Forward direction digital input FW.
ON /+BV = input active, switch closed.
OFF / GND = input non-active, switch open.
9) BACKWARD SWITCH: The level of the Reverse direction digital input BW.
ON /+BV = input active, switch closed.
OFF / GND = input non-active, switch open.
10) ENABLE SWITCH: The level of the Enable digital input.
ON /+BV = input active, switch closed.
OFF / GND = input non-active, switch open.
11) VOLTAGE BOOSTER: This is the booster voltage supplied to the motor in load condition; It is expressed in a per-
centage of the full voltage.
12) BATTERY VOLTAGE: Level of the battery voltage measured at the input of the key switch.
