active low or active high inhibit, then on a correctly functioning controller the voltage at
Charger/Programmer Pin 4 should be as follows. If the voltages are incorrect then
check the wiring to charger socket or other inhibit source.
Active low: Pin 4 to Battery -ve : V
BATT
± 0.5V or 0V ± 0.5V to inhibit
5V ± 0.5V to drive
Active high: Pin 4 to Battery -ve : V
BATT
± 0.5V or 0V ± 0.5V to drive
5V ± 0.5V to inhibit
If input 1 input is functioning correctly and the trip is still present, then the controller
may be defective. Refer to section 5.
3.6.2 Inhibit 2 Active
This occurs when the controller detects that inhihit 2 is activated. The operation of
Inhibit 2 will depend upon the program settings of the controller and the scooter on
which it is being used.
Check all wiring and switches connected to Inhibit 2 (Tiller Connector Pin 6). If these
appear to be in working order, then the controller may be defective.
If the voltages are correct and the trip is still present, then the controller may be defective.
Refer to section 5.
3.6.3 Inhibit 3 Active
This occurs when the controller detects that inhibit 3 is activated. The most common
use for inhibit 3 input is for disabling the vehicle’s drive when the Off-board charger is
connected via the tiller. Check that the battery charger is disconnected. If the charger
is disconnected, then the voltage at Tiller Connector Pin 14 should be checked.
Depending on whether the controller is programmed to active low or active high inhibit,
then on a correctly functioning controller the voltage at Tiller Connector Pin 14 should
be as below. If the voltages are incorrect then check the wiring to charger socket or
other inhibit source.
Active low: Pin 14 to Battery -ve : V
BATT
± 0.5V or 0V ± 0.5V to inhibit
5V ± 0.5V to drive
Active high: Pin 14 to Battery -ve : V
BATT
± 0.5V or 0V ± 0.5V to drive
5V ± 0.5V to inhibit
If inhibit 3 input is functioning correctly and the trip is still present, then the controller
may be defective. Refer to section 5.
3.7 Trip Type 7 - Throttle Trip
The throttle potentiometer is supplied with a varying signal from the controller. To check
a Wig-wag or Unipolar type throttle potentiometer, firstly disconnect it from the
controller. Measure the resistive properties of the throttle potentiometer using a meter
across each end. Divide this figure by 2 to give the centre of the potentiometer. This is
the center point that the throttle should be set to. A tolerance of ± 3% is permitted
when setting the throttle to the center of the potentiometer.
