Puma 20/40
Possible cause
Joystick Displaced at
Power-up
Communication Error
Inhibit 2 Active
Inhibit 3 Active
Actuator Motor Wiring Trip
Current Limit Active
High Temperature
Remedy
The most common cause of this trip is if the joystick is deflected away from the center when the
control system is being switched on. When the control system is switched on, the battery gauge
will blink for a short time. Check that the user is not deflecting the joystick before the blink finishes.
If the problem persists, refer to section .37.
The most likely cause of a communication error is a defective cable between the Power Module
and the Joystick Module. The cable should be checked for damage, and replaced if found to
have a fault. The Joystick Cable can only be replaced by a person authorized by the wheelchair
manufacturer. Refer to Section 1.3 for the replacement procedure.
If the problem persists then either the Power Module or the Joystick Module could be defective.
Refer to Section 5.
This occurs when the Inhibit 2 Input is active. The Inhibit 2 input is via the INH-2 way connector
and is normally associated with speed limit or actuator functions. The operation of Inhibit 2 will
depend upon the programmed settings and the wheelchair on which it is being used. Check all
wiring and switches connected to Inhibit 2. If these appear to be in working order, then the Power
Module may be defective. Refer to Section 5.
This occurs when the Inhibit 3 Input is active. The Inhibit 3 input is via the 3 way on-board charger
(OBC) and is normally associated with this function. The operation of Inhibit 3 will depend upon
the programmed settings and the wheelchair on which it is being used. Check all wiring, switches
and OBC (if fitted) connected to Inhibit 3. If these appear to be in working order, then the Power
Module may be defective. Refer to Section 5.
This occurs when the control system detects a fault in the wiring to either actuator motor. Check
the motor connectors and wiring. If the trip is still present after the above checks have been made,
then the Power Module may be defective. Refer to Section 5.
This occurs when the control system operates above the Current Limit Threshold for a periode of
time greater than the Current Limit Time. It has been designed to notify the Healthcare Technician
that the control system has operated outside of its programmed range.
This occurs when the control system reaches its Temperature Threshold and thus becomes to
hot. The controller will not allow drive until the controller to cooled down. An entry is made in the
system log each time the controller gets too hot and goes out of drive.
