Description of TESTER 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
listing shows the measurements that may be made :
< DRIVE CONTROLLER >
1.
VMN : the voltage effectively dropped across the
MOSFET. It is measured between BATT-and VMN.
2.
MOTOR VOLTAGE : level of traction motor voltage
measured between S2 and BATT+.
3.
MOTOR CURRENT: the current flowing in the
traction motor armature.
4.
BATTERY VOLTAGE : level of battery voltage
measured at the input to the key switch.
5.
TEMPERATURE : the temperature measured on the
aluminum heat skin holding the MOSFET devices.
6.
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.
7.
FORWARD SWITCH : the level of the Forward
direction digital entry.
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.
ON/ +VB = active entry of closed switch.
OFF/ GND = non active entry of open switch.
9.
CUTBACK SWITCH : Not used
10.
ENABLE SWITCH : the level of Enable switch
digital input.
ON/ +VB = active entry of closed switch.
OFF/ GND = non active entry of open switch.
11.
HANDBRAKE : the level of the Handbrake
microswitch.
ON/ GND = active entry of the Handbrake switch.
OFF/ +VB = non active entry of the Handbrake switch.
12.
BRAKE SWITCH : the level of the Pedal brake
microswitch.
ON/ +VB = active entry of the Pedal brake switch.
OFF/GND = non active entry of the Pedal brake
switch.
13.
HANDLE/SEAT SW. = the level of the Seat
microswitch.
ON/ +VB = active entry of the Seat microswitch.
OFF/ GND = non active entry of the Seat
microswitch.
14.
MOTOR TEMPERAT. = the level of the Drive
Motor temp. switch.
ON/ GND = active entry of the Motor temp. switch.
OFF/ +VB = non active entry of the Motor temp.
switch.
< PUMP CONTROLLER >
1.
VMN : the voltage effectively dropped across the
MOSFET. It is measured between BATT-and VMN.
2.
MOTOR VOLTAGE : level of traction motor voltage
measured between P2 and BATT+.
3.
MOTOR CURRENT: the current flowing in the pump
motor armature.
4.
BATTERY VOLTAGE : level of battery voltage
measured at the input to the key switch.
5.
TEMPERATURE : the temperature measured on the
aluminum heat skin holding the MOSFET devices.
6.
LIFTING CONTROL : the voltage of the lifting
potentiometer's wiper(CPOT). The voltage leve
is shown on the Left Hand Side of the Console
Display and the value in percentage is shown on the
Right Hand Side.
7.
LIFTING SWITCH : Not used
8.
DIGITAL INPUT #1 : Not used
9.
1ST SPEED SWITCH : the level of the Tilt speed
microswitch.
ON/ +VB = active entry, microswitch closed.
OFF/ GND = non active entry, microswitch open.
10.
2ND SPEED SWITCH : the level of the Aux1
speed microswitch.
ON/ +VB = active entry, microswitch closed.
OFF/ GND = non active entry, microswitch open.
11.
3RD SPEED SWITCH : the level of the Aux2
speed microswitch.
ON/ +VB = active entry, microswitch closed.
OFF/ GND = non active entry, microswitch open.
12.
MOTOR TEMPERAT : the level of the Pump Motor
temp. switch.
ON/ GND = active entry of the Motor
OFF/ +VB = non active entry of the Motor temp.
