WARNING! Risk of Death or Serious Injury if the Maximum Recommended Limits are Exceeded
Safety Lockouts and Limit Switches should be set up to best meet the needs of the user without
compromising the overall stability of the wheelchair.
NOTE:
Additional safety limits and lockout switches may be required for more complicated/ specialized
seating systems. For information on limits/lockouts that are not identified in this manual, please contact
our Technical Service Department for assistance.
WARNING! Risk of Serious Injury or Damage.
Following any limit or lockout adjustments,
always
test the seating system over the full range of motion
(i.e.; tilt, recline, elevate) to verify the revised set-up is functioning properly and ensure that there
are no resulting stability or interference issues.
WARNING! Risk of Serious Injury or Damage.
• ALWAYS ensure the wheelchair base is on a level surface when setting/adjusting limits.

4.3.2 ELEVATE/REACH REDUCED DRIVE SPEED (RDS) LIMIT
The Rovi Upfront MPS is configured to put the wheelchair into
Reduced Drive
Speed (RDS)
when the seating system begins elevate/reach function is
activated. The RDS Limit utilizes a microswitch to trigger the seating system
into reduced drive speed as soon as the seating system is elevated beyond
the home (fully lowered) position.

4.3.1 TILT/RECLINE DRIVE LOCKOUT (DLO)
AND
REDUCED DRIVE SPEED (RDS) LIMIT
All tilt or recline power positioning systems are equipped with a
Drive Lockout (DLO
) Limit to prevent the
wheelchair from being driven when the seating system is tilted or reclined beyond a pre-determined safe angle.
The DLO limit is configured using a programmable
Tipsy Angle Sensor
Tipsy Angle Sensor
(see section 4.3.5).
Note:
The Tipsy Angle Sensor offers a
Reduce Drive Speed (RDS)
setting that will trigger the wheelchair base
to drive at approx. 25-30% of its maximum speed when the back angle extends beyond the home position. Reduced
Drive Speed is typically set to engage between 10-20° and will stop when the Max DLO limit is reached)
Tilt and/or Recline Function (With Reduced Drive Speed):
Max. DLO Angle = 30°
Tilt and/or Recline Function (Without Reduced Drive Speed):
Max. DLO Angle = 25°
