Example of R-10 Fault Isolation

1. In this example, one of the right motor being

disconnected (ﬁ gure.5.4.1). The hand control

displays the fault and the power chair will not

operate.

2. To troubleshoot this problem, refer to Table 1,

Error Codes.

3. From this error we see that the problem is

being recorded in the PM (Control Module).

4. The hand control tells us that motor 2 (M2) has

the error and it is with the brake circuit. Motor 2

is the right motor.

5. Table 1 informs us to, “Verify that the right motor

is connected to the control module. Complete the

Motor and Gearbox Inspection section of this

manual.”

6. The next step is to complete the Motor and

Gearbox Inspection section of this manual and

retest.

Power Chair Will Not Drive Full Speed

An external micro-switch is mounted next to the actuator in the rear of the tilt system. This micro-switch

is open when the tilt is lowered. The opening of this micro-switch blocks a signal from being sent to

the control module through the 6-pin connector located on the back of the tilt. The absence of this

signal informs the control module that the tilt is less than 20 degrees and that maximum speed should

be used. If the tilt is more than 20 degrees, the switches closes and invokes “creep” speed. Creep

speed is a predetermined speed programmed at time of manufacture. Creep is indicated by a “turtle”

on either the hand control or Omni.

1. “Creep” speed as indicated by the turtle on the

hand control ("A" ﬁ gure 5.4.2).

2. Tilt the seating system to the rear.
