Chair Won't Drive in Creep Speed When Tilted
An external micro-switch is mounted next to the actuator in the rear of the lift system. This micro-switch
is closed when the tilt is lowered. When micro-switch is closed, it sends a signal from the control
module through the 6-pin connector. The presence of this signal informs the control module that the
tilt is less than 20 degrees and that maximum speed can be used. If the tilt is more than 20 degrees,
the switche 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 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.

fi
gure 4.9.1), when
seating is horizontal, contact Sunrise Technical
Service for assistance. The programming for the
power chair is incorrectly set.
3. If the turtle is not shown when the the seat is
at full tilt, Use the hand control and tilt the seating
system just beyond 20 degrees.
4. Locate the 6-pin connector (B) on the rear of
the tilt (

gure 4.9.2)
5. Disconnect the 6-pin connector leading to the
control module by pressing down on the top of
connector as shown in (
