Power Recline with Power Shear Reduction
The New Power Recline with Power Shear Reduction is modeled after the Quickie Smart Seat with the additional
enhancement of operation by the Quickie iQ Electronics powered by Delphi. Electrical adjustments for the New
Power Recline are either by using the HHP or Quickie iQ. The three new adjustments available using the HHP or
Quickie iQ are:
Shear Program – This program allows the use of the HHP or Quickie iQ program to map the shear amounts 1.
in relation to the back angle.
Enable – Enable selects the Power Shear Program.2.
Tuning Factor – Tuning Factor smoothes the Shear Program (shear mapping) to prevent jerky shear reduction. 3.
The factory setting is 10 and the range is 1 to 100. One (1) is the smoothest setting, 100 follows the shear
map exactly.
The recline system uses encoders in the actuators to provide seat position to the Delphi system. This system has
been improved over the Smart Seat by providing automatic “re-home” capabilities. Automatic re-home is performed
anytime the seat is operated past a certain point and micro-switches are closed. These micro-switches, known as
Counter Reset Switches (CSR), tell the Delphi system the exact position of the actuator.
Automatic speed-reduction, known as Creep, is controlled by the position of the back. Anytime the back angle is 15
degrees past vertical in any combination of Tilt or Recline, the wheelchair reverts to a programmable Creep Profi le.
This profi le may be modifi ed by either the HHP or Quickie iQ to run slower than the factory settings. Creep speed is
a percent of maximum Creep speed programmed by Sunrise Medical.
Prior to performing any troubleshooting, “re-home” the recline and shear system using the HHP.
It is also a good idea to use the HHP or Quickie iQ to troubleshoot the system prior to performing any component
testing. Refer to Fault Isolation Procedures Using Quickie iQ or HHP in this tech manual.
Once the wheelchair has been re-homed and then tested using the HHP or Quickie iQ, complete the following sec-
tions to test the individual components.
To remove the rear shroud for service work, refer to the section covering Recline Actuator Removal in this tech
manual.
