Tilt/Recline Drive Lockout (DLO) Limit
All tilt and recline seating 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 total angle. The total angle
can be any combination of seat angle, backrest angle and/or
surface angle. Drive lockout only responds when you adjust
angles in standstill.
The DLO limit is set to a maximum of 30° (120°-90°).

Reduced Drive Speed (RDS) Limit
Seating systems that are configured with a scissor lift
module or the tilt module are configured/programmed with
a Reduced Drive Speed limit. The limit utilizes a microswitch
to trigger the seating system into reduced speed drive as
soon as:

• the seating system is raised to a pre-determined height
(4 in [100 mm]) beyond the home (fully retracted)
position, or
• the seating system is tilted outside of the
pre-determined angle range (110°-90°).

Maximum Back Angle Limit
The maximum tilt limit establishes the maximum back angle
for the seating system at tilt/recline combined. The function
of this limit is to prevent the back angle from extending
beyond a maximum pre-set angle. Ultra Low Maxx seating
systems are typically preset at the factory to the maximum
allowable angle and do not require any further adjustment
unless the maximum angle needs to be decreased (see
hazard statement below).
Tilt/Recline: Maximum Tilt/Recline Limit = 168°
