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
voltage, current and temperature. The following definition listing shows the relative
measurements :
1) BATTERY VOLTAGE:
level of battery voltage measured at the input to the key
switch.
2) MOTOR CURRENT:
the current flowing in the drive motor armature.
3) FIELD CURRENT:
the current flowing in the drive motor field winding.
4) VMN:
the voltage effectively dropped across the MOS. It is measured between B-
and VMN.
5) TEMPERATURE:
the temperature measured on the aluminum heat sink holding the
MOSFET devices.
6) 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.
7) 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.
8) 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.
9) TILLER SWITCH:
the level of the Handle/Seat Microswitch digital entry
(pin A4).
ON / + VB = active entry of closed seat switch.
OFF / GND = non active entry of open seat switch.
10) BELLY SWITCH:
the level of the digital entry from Belly Button microswitch
(pin A5).
ON /+ VB = active entry, B SW closed.
OFF / GND = non active entry, B SW open.
11) DIGITAL INPUT #2 (A9):
(only with option BACKING FUNCTION PROGRAMMED
OFF) the level of the auxiliary microswitch when used for speed reduction.
ON / GND= active entry of speed reduction microswitch.
OFF / +VB = non active entry of microswitch.
12) BACKING INPUT (A9):
(only with option BACKING FUNCTION PROGRAMMED
ON) the level of auxiliary microswitch when used as backing enable.
ON / +VB = active.
13) HARD & SOFT (A8):
level of the HARD & SOFT microswitch.
ON / +VB = active.
14) BATTERY CHARGE:
battery charge indication %.
