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 closed when the tilt is lowered. The closing of this micro-switch allows a signal to be being sent
to the control module through the 6-pin connector located on the back of the tilt. The signal informs
the control module that the tilt is less than 16 degrees and that maximum speed should be used. If
the tilt is more than 16 degrees, the switches opens and invokes “Creep” Speed. Creep speed is a
predetermined speed programmed at time of manufacture. Creep is indicated by a “turtle” on either
the color Joystick or Omni.
1. Tilt the seat all the way back and observe the
hand control or Omni to see if the turtle symbol is
displayed.
If the turtle (A) is displayed (
fi g 5.5.1), contact
Sunrise Medical Technical Service for assistance.
If no turtle is displayed, continue to step 2.
2. Tilt the seating system beyond 16 degrees.

3. Locate the 6-pin connector on the rear of the
tilt. (
fi g 5.5.2). Disconnect the harness from the tilt
module.
4. Test the micro-switch by performing the following
test:
a. Ensure that the tilt is beyond 16 degrees.
b. Use the multimeter and measure continuity
between the indicated pins on the pin connector
mounted on the tilt. When the seat is tilted the
indication should be open (
fi g 5.5.3).
If it is closed, replace the micro-switch.
Refer to tilt actuator and micro-switch removal
section of this manual.
Re-test as necessary.
