6.2 TESTER DESCRIPTION OF THE FUNCTIONS
The most important input or output signals can be measured in real time using the
TESTER function of the console. The Console acts as a multimeter able to read volt-
age, current and temperature. The following definition listing shows the relative meas-
urements :
1) BATTERY VOLTAGE:
level of battery voltage measured at the input to the key
switch.
2) MOTOR VOLTAGE:
the voltage appearing across the drive motor. It is measured
between B+ and VMN.
3) MOTOR CURRENT:
the current flowing in the drive motor armature.
4) FIELD CURRENT:
the current flowing in the drive motor field winding.
5) VMN:
the voltage effectively dropped across the MOS. It is measured between B-
and VMN.
6) TEMPERATURE:
the temperature measured on the aluminum heat sink holding the
MOSFET devices.
7) ACCELERATOR:
the voltage of the accelerator potentiometer 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.
8) FORWARD SWITCH:
the level of the Forward direction digital entry MA (pin B6).
ON /+ VB = active entry of closed switch.
OFF / GND = non active entry of open switch.
9) BACKWARD SWITCH:
the level of the Reverse direction digital entry MI (pin B4).
ON /+ VB = active entry of closed switch.
OFF / GND = non active entry of open switch.
10) HANDLE/SEAT SWITCH:
the level of the Handle/Seat Microswitch digital entry
(pin A5).
ON / + VB = active entry of closed seat switch.
OFF / GND = non active entry of open seat switch.
11) QUICK INVERSION:
the level of the digital entry from Belly Button microswitch
(pin B5).
ON /+ VB = active entry, B SW closed.
OFF / GND = non active entry, B SW open.
12) CUTBACK SWITCH 1:
the level of the Speed Reduction 1 Microswitch SR1.
ON / GND = active entry of speed reduction microswitch.
OFF / + VB = non active entry of microswitch.
13) CUTBACK SWITCH 2:
the level of the Speed Reduction 2 Microswitch SR2.
ON / GND= active entry of speed reduction microswitch.
OFF / +VB = non active entry of microswitch.
