SEATING SECTION
Follow the cable to another connector leading to 5.
the actuator if the resistance is excessive.
Disconnect this connector and check armature 6.
resistance through the pins indicated in the photo
(Fig 3.104). Nominal resistance is 2 to 4 ohms.
Replace the 6-pin cable leading from the QMAC to 7.
the cable leading to the actuator if the resistance
is correct
Replace the actuator if the resistance is out of 8.
tolerance and the actuator does not run. Refer to
Recline Actuator Removal section in this manual.
On the QMAC, move the Recline actuator cable 9.
from its port to another port (i.e. Tilt). Operate the
recline system. If the system operates correctly,
replace the QMAC. Refer to the Recline Actuator
Removal section in this manual.
The Shear Actuator will not run, or runs erratically
Complete the following Test Procedure to test the Shear
Actuator. Use the HHP to re-home the chair prior to
completing any tests.
To test the current drain and operation of the 1.
encoder switches of the Shear actuator, complete
the Fault Isolation Procedures Using Quickie iQ or
HHP. Replace the shear actuator if the procedure
fails. To continue testing, complete the following
procedures.
Locate the QMAC mounted on the back of the 2.
wheelchair (Fig 3.105).
Disconnect the 6-pin female connector(C) leading 3.
to the Shear port of the QMAC (Fig 3.106).
