TESTER
AC2 LIFTING UNIT
MOTOR VOLTAGE:
voltage supplied to the motor by the inverter; it is expressed as a
percentage of the full voltage (which depends on the battery voltage).
FREQUENCY:
frequency of the voltage and current supplied to the motor.
ENCODER:
speed of the motor, expressed in the same unit as the frequency; this
information comes from the speed sensor.
SLIP VALUE:
difference between the rotating field frequency and the motor shaft
frequency (measured by the encoder)
CURRENT RMS:
Root Mean Square value of the motor current.
TEMPERATURE:
temperature measured on the aluminum heat sink holding the MOSFET
devices.
MOTOR TEMPERATURE:
temperature of the motor; if the option is programmed "None"
it shows 0°.
SEAT SWITCH:
state of the Seat Microswitch digital input.
ON / +VB* = active input, closed switch.
OFF / GND = non-active input, open switch.
ACCELERATOR:
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.
LIFTING SWITCH:
state of the lifting switch.
1 ST SPEED SWITCH:
state of the tilt switch of the pump (%).
2 ND SPEED SWITCH:
state of the side-shift switch of the pump (%).
3 RD SPEED SWITCH:
state of the 4th
lever switch of the pump (%).
4 TH SPEED SWITCH:
state of the 5th speed switch of the pump (%).
HYDRO SPEED REQ.:
state of the hydro speed request of the pump.
CUTBACK SWITCH:
state of the Speed Reduction Microswitch.
ON / GND = active input, opened switch.
OFF / +VB* = non-active input, closed switch.
CUTBACK SWITCH
2
:
state of the Speed Reduction Microswitch.
ON /
+VB*
= active input, opened switch.
OFF /
GND
= non-active input, closed switch.
VOLTAGE BOOSTER:
voltage booster supplied to the motor in load condition; it is expressed
as a percentage of the full voltage.
BATTERY VOLTAGE:
level of battery voltage measured with the key switch ON.
COS FI:
cos
ϕ
(real time calculated) of the motor.
BATTERY CURRENT:
battery current (not measured but calculated).
BATTERY CHARGE:
percentage of battery charge.
* = The console shows “ + VB “, but the real voltage is +5V
