Power Chair Will Not Drive in Creep Speed When Tilted

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. Tilt the seat all the way back and observe the

hand control or Omni to see if the turtle symbol

"A" is displayed.

2. If the turtle is displayed (ﬁ gure 5.6.1), contact

Sunrise Technical Service for assistance. The

programming for the power chair is incorrectly

set.

3. Use the hand control and tilt the seating system

beyond 20 degrees.

4. Locate the 6-pin connector "B" on the rear of

the tilt (ﬁ gure 5.6.2).

5. Disconnect the connector leading to the control

module

6. Test micro-switch with the following test.

a. Ensure that the tilt is beyond 20 degrees tilt.

b. Use Multimeter and measure continuity

between the indicated pins below on the 6-pin

connector mounted on the tilt. When seat is tilted

the indication should be closed (ﬁ gure 5.6.3).

c. If it is open, replace the micro-switch assembly.

Refer to Tilt Actuator and Micro-Switch Removal

section 7 of this manual.

d. Retest as necessary.
