OVERVIEW
The Curtis enAble® 40 Powerchair Control System provides outstanding
versatility packaged in an easy-to-install, easy-to-use set of three components:
a powerbase (motor controller) with optional seat actuators and lights, an
ergonomic handcontrol with an intuitive icon LCD display, and an optional
compact attendant control. The enAble® 40 provides the perfect solution for
rear, mid, and front drive powerchairs. With its advanced seating control, it
will also be the right fit for many Rehab chair configurations.

1 — OVERVIEW

Powerchair Control System:
powerbase (1740),
user handcontrol (1741),
attendant control (1742).
Like all Curtis motor control products, the enAble® 40 system offers superior
control of drive performance, delivering a ride that is smooth and responsive in
all modes: acceleration, deceleration, forward or backward, on smooth indoor
surfaces, up a hill, or over gravel. Key features include
Powerbase:
✔ Best-in-market drive feel and control for front-, mid-, and
rear-wheel drive chairs.
✔ Full 50 and 75 amp power ratings in a rugged, compact, and
sealed enclosure.
✔ Revolutionary MyChair™ parameter tunes the overall chair
feel to fit each user’s unique needs — with a single parameter.
✔ Patented Auto-Trim automatically and continuously corrects
steering alignment, which can be thrown off by tire, motor,
and gearbox wear and replacement.
✔ Integration of lights and actuators provides these options at a
minimum cost and without installation of additional wiring
or modules.
✔ Four independent configurations in each powerbase, with
every parameter stored.

1 — OVERVIEW
✔ Three flexible Multi-Function input pins for advanced seat
actuator inhibits, speed limiting, and swivel chair functions
usually found only on high-end systems.
✔ Powerbase software is upgradable in the field or in the factory.
✔ Onboard or offboard charging up to 8 amps accommodates
high capacity batteries.
✔ Compatible with the Curtis 1313 handheld programmer and
1314 PC Programming Station.
User handcontrol:
✔ Stylish and ergonomic design.
✔ Intuitive at-a-glance icons on LCD display with backlight,
viewable in any lighting.
✔ Four keypad configurations that match the application.
✔ Up to nine programmable speed modes are quickly and easily
accessible while driving.
✔ Industry standard 3-pin XLR charger/programmer port.
✔ Key-lock function to lock out unwanted drivers.
✔ Rugged and flexible communications cable.
✔ Field replaceable joystick and communications cable.
Attendant control:
✔ Easily connected to the system, with plug-in-line autoconnect
feature.
✔ Programmable takeover control.
✔ Field-replaceable joystick and communications cable.
The enAble® 40 system introduces a number of unique features. Here are some
brief descriptions.
Configurations
The powerbase stores four “configurations” — which are complete setups with
data settings for every parameter. This means the OEM can have four configu-
rations in one product—in effect, four products in one. The dealer can stock
just one “4-in-1” model and use the Configuration parameter to select the most
appropriate data block for each chair and each customer.
Each configuration is a complete setup, including two profiles for each.
This means the 1740 actually holds eight different ready-made setups.

1 — OVERVIEW
Profiles
Each configuration in the enAble® 40 has two complete operational profiles, each
with its own speed, acceleration, and other response parameters. The profiles
are used two ways:
• MyChair™ — where Profiles 1 and 2 can be blended to provide
a range of “feels,” through very simple and safe programming.
• Swivel Chair Mode — where Multi-Function Input 3 selects
between Profile 1 or Profile 2.
MyChair™
The MyChair™ function provides a very fast and simplified way for the therapist
to custom tune a chair to a specific user. With this one parameter, the therapist
can adjust the aggressiveness and speed of the chair to suit the situation.
MyChair™ works by blending the key parameters from Profiles 1 and 2
as the MyChair™ parameter is adjusted from 1.0 (Profile 1) to 2.0 (Profile 2) in
0.1 steps (for 11 different “blends”). Normally the OEM sets the parameters of
Profile 1 for a slower and less responsive chair and Profile 2 to the fastest and
most responsive settings. By adjusting the MyChair™ parameter, the therapist
can easily select between factory-determined safe minimum and maximum drive
configurations without understanding the details of chair stability, compensa-
tion, turn control, etc.
Swivel Chair
The Swivel Chair feature allows the Mode/Seat input to select between Profiles
1 and 2 while automatically switching the motor drive directions and wheel
position parameters, for chairs that have a two-position seat. These chairs pro-
vide front-wheel drive for high speed outdoor mode and rear-wheel drive for
indoor mode by simply rotating the seat 180 degrees.
MyChair™ does not work in Swivel Chair mode. Profile 1 is used when
the switch is open and Profile 2 when the switch is closed.
Selectable Speed Modes
The therapist can select from 2 to 9 different speed modes for the user to access
with the up/down speed mode buttons on the handcontrol. The therapist can
set each speed mode independently in a linear or non-linear progression. This
allows the therapist and user to select just the right number and speed for all
conditions of driving. Some need only “indoor” and “outdoor” modes while
other users prefer to use three or four different speed modes just around the
normal walking pace to make travel with pedestrian friends and family easier.

Multi-Function Inputs
The enAble® 40 introduces a level of seat and vehicle speed limiting/inhibit
modes normally found on only the highest end Rehab systems. Three Multi-
Function Inputs on the powerbase plus the Inhibit on the handcontrol charger
port allow for flexible charger configurations (onboard/offboard), seat actuator
halts in one or both directions, and up to four separate speed limits linked to
these inputs.
Possible applications include:
• Inhibit drive and lock out tilt back (but not height or tilt
forward) for an offboard charger.
• Limit the drive speed when the seat is tilted, with a second
limit if the seat is raised.
• Provide an end-of-travel for any seat function.
• Lock out lift when the seat is reclined.
• Add a variable speed limit based on a seat tilt pot or seat
height pot.
Auto-Trim
As the chair is used the gearbox, motor brushes, and tires wear. This adversely
affects the straight-line drive performance and “trim” of the chair. The Auto-
Trim feature continuously monitors the driving behavior of the chair and
corrects the trim automatically to provide consistent straight-line performance
over the lifetime of the chair.
Dynamic Turn Radius Control
As the chair drives faster, its momentum increases dramatically and making
quick sharp corners can upset the balance and steering feel of the chair. The
Curtis proprietary Dynamic Turn Radius Control tempers the aggresssiveness
of the steering as a function of speed to provide an always-in-control feel at
every speed and through every turn.
Familiarity with your Curtis enAble® Powerchair Control System will help you
install and operate it properly. We encourage you to read this manual carefully. If
you have questions, please contact the Curtis office nearest you.
