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

Fig. 1 Curtis enAble® 40

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.

2 Curtis enAble® 40 Manual, Rev. E

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.

Curtis enAble® 40 Manual, Rev. E

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.

4 Curtis enAble® 40 Manual, Rev. E

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.
