elevated if equipped with a power seat and/or tilt.
If tilted, reclined, or elevated, return all actuators
to neutral position and retest.
MCM will
fl ash actuator that indicated to the chair 4.
a creep condition. See table for actuator signaling
creep.
Reset Encoders. Bring actuator to home position.
5.
Move actuator away from home past the encoder
reset switch. Move actuator back to home position.
Retest chair. Repeat for all actuators connected
to the chair.
Recline, check Encoder Reset:
6.
Locate the Encoder Reset and EOT switch a.
assembly (Fig 3.56)on the back of the chair.
Follow the cable to the 6 pin connector on the
PC board.
Disconnect the 6-pin connector (A) leading from
b.
the Encoder Reset and EOT switch assembly.
Connect a multimeter across the two white wires
c.
of the 6-pin connector. Check for continuity when
the Encoder Reset switch is open and closed by
manually operating the rocker switch.
Replace the Encoder Reset and EOT switch
d.
assembly if the continuity tests fail. Retest the
