2.2.3 Display is steady
No trip is currently detected by the controller.
• A trip may have occurred previously, read the controller’s diagnostic log, then refer to section 3 to establish the
trip type.
2.2.4 Display does not illuminate
No power is reaching the controller.
• Ensure the batteries are fully charged and that all connections between batteries and the controller are made.
• If these connections are good, then the controller may be defective, refer to Section 5.
2.3 Other conditions
This covers conditions that are not displayed as trip codes or on the battery gauge. This may be because: either the controller
cannot switch on; the condition is not considered critical enough to force a trip or the controller cannot detect the condition.
2.3.1 Controller will not switch on
•
Check the battery connections to the controller. If these appear to be good, then the controller may be
defective, refer to section 5.
•
Check the cable from the controller. If this appears to be good, then the controller may be defective, refer to
section 5.
2.3.2 Wheelchair drives slowly
This could be caused by one of the following.
•
The controller has been incorrectly programmed.
•
Defective motor or defective brake.
2.3.3 Wheelchair will not drive in a straight line
This could be caused by a defective motor or defective brake.
2.3.4 One motor or brake becomes very warm
This could be caused by a defective motor or defective brake.
2.3.5 Batteries discharge very quickly
The batteries can discharge very quickly for several reasons, these are described below.
•
Worn or damaged batteries – check battery condition.
• Charger defective or incorrect charger being used – check charger operation (refer to wheelchair’s operating
manual).
• Incorrect batteries being used – refer to wheelchair manufacturer’s instructions for correct battery types.
•
One motor or brake jamming.
The ambient temperature has a significant effect on battery capacity. Therefore, if the
temperature is lower than normal the wheelchair’s range will be reduced. In this situation, the
battery gauge still gives an accurate state-of-charge reading.
