40-Series Manual, Rev. B

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

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.

Curtis enAble

40-Series Manual, Rev. B

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 12 amps accommodates

high capacity batteries.

✔ Compatible with the 1311 and 1314 programmers.

User handcontrol:

✔ Stylish and ergonomic design.

✔ Intuitive at-a-glance icons on LCD display with backlight,

viewable in any lighting.

✔ Three keypad conﬁgurations that match the application.

✔ 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 keypad, joystick, and communications cable.

Attendant control:

✔ Easily connected to the system, with plug-in-line autoconnect

feature.

✔ Programmable takeover control.

✔ Field-replaceable keypad, joystick, and communications cable.

The 40-Series 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-Series Manual, Rev. B

1 — OVERVIEW

Proﬁles

Each conﬁguration in the 40-Series 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.

Curtis enAble

40-Series Manual, Rev. B

Multi-Function Inputs

The 40-Series 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

inhibits 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.

INSTALLATION AND WIRING

INSTALLING THE 40-SERIES SYSTEM

The 40-Series modules—powerbase, user handcontrol, and attendant con

trol—have been designed for convenient installation.

Mounting the 1740 Powerbase

The powerbase is easily mounted to the chair by means of two bolts, and can

be oriented in any position.

A groove on the underside of the powerbase simpliﬁes alignment when

the powerbase is mounted on a tube, and provides stability.

Curtis enAble

40-Series Manual, Rev. B

Mounting the 1741 Handcontrol

Brass inserts in the user handcontrol allow it to be securely mounted and re

moved/reinstalled many times. The handcontrol is designed to ﬁt both tube

and plate mounting systems.

POWERBASE WIRING

Wiring for the 1740 powerbase is shown in Figure 5. The connections to the

14-pin connector are optional, depending on the level of functionality desired.

For use with the simplest handcontrol (the basic drive-only version), no logic

connections are required; for use with the full featured handcontrol (drive with

lights and seat actuators), all the connections shown in Figure 5 are required.

Additional features can be added to the system by wiring additional components

to the Multi-Function pins (4–7); see Figure 6.

The motor and battery connector housings have been speciﬁcally designed

for the enAble 40 system and must be purchased directly from your Curtis

dealer or sales representative. The electrical connectors are standard AMP parts.

Curtis also provides a kit with all the parts required to connect the high power

wiring to the powerbase. See Appendix C for part numbers.

14-pin logic connector

The mating connector is 14-pin Molex Mini-Fit Junior, p/n 39-01-2140. You

should use the matching Molex pins, p/n 44476-3112, which are suitable for

high current, and 18–24 AWG wire. The pin-out is as follows:

CONNECTING THE CONTROL MODULES

The communications cable on the 1741 user handcontrol and on the 1742

attendant control each terminate in a plug that ﬁts into the powerbase’s 6-pin

connector. The attendant control’s cable includes a Y-junction into which the

user handcontrol’s cable connects, as shown in Figure 7.

5-pin charger/programmer port

The user handcontrol has a 5-pin port that accommodates a battery charger

and a 1311 programmer (although not at the same time). The charger plug’s

three pins ﬁt into sockets 1, 2, and 3. The programmer plug’s two pins ﬁt into

sockets 4 and 5. Both plugs are designed to snap securely into the port.

Allowable current for a charger in this port is 8 amps continuous (12 amps peak).

The inhibit pin (pin 3) halts all chair travel during charging. Additionally,

it can prevent speciﬁc actuator movements.

USER HANDCONTROL

(1741)

The 40-Series handcontrol is designed to be user-friendly. The keypad buttons

are responsive and clearly marked. The LCD display is crisp and clear, with

intuitive icons and backlighting to enhance daytime and nighttime readability.

The communication cable is thin, ﬂexible, and ﬁeld replaceable.

The handcontrol is the main user interface to the control system. All user

commands come from the handcontrol’s keypad and joystick. The handcontrol

is also the information center of the system. All faults, errors, limits, and status

(operational characteristics) are displayed on its LCD display.

JOYSTICK

Moving the joystick straight forward and straight backward proportionately

controls the travel speed of the chair. Neutral (center position) always requests

no movement. Two deadbands, one around neutral and one at the full throw

(against the gate), provide a zone at each extreme where small movements—caused

by tremors, bumps, etc.—do not cause changes in vehicle speed.

Moving the joystick right and left (side to side) proportionately controls

the turning radius and turn rate of the vehicle.

KEYPADS

Three versions of the handcontrol are available: Drive Only, Drive with Actua

tors, and Drive with Actuators and Lights.

Three keypad layouts correspond to the three versions:

Drive Only (4 buttons):

■ on/off, ■ horn, ■ speed up, ■ speed down.

Drive + Actuators (6 buttons):

■ on/off, ■ horn, ■ speed up, ■ speed down, ■ seat mode 1, ■ seat mode 2.

Drive + Actuators + Lights (8 buttons):

■ on/off, ■ horn, ■ speed up, ■ speed down, ■ L turn, ■ R turn, ■ headlights, ■ mode.

The functions of the various buttons are described in the following pages.

3 — USER HANDCONTROL

Curtis enAble

40-Series Manual, Rev. B

Drive Only (4-button keypad)

The Drive Only keypad has four buttons: On/Off, Horn, Speed Up, and Speed

Down. These four basic buttons are standard on all the keypad versions.

On/Off Button

The Power On/Off button is located at the top of the keypad, above the display.

This button can also be used to lock the chair; see Handcontrol menu, page 24.

Horn Button

Pressing the Horn button sounds the horn. The horn is generally used to alert

nearby pedestrians to the oncoming chair. Beyond this basic function, the

horn can be programmed to provide several other functions: a back-up alarm,

audible feedback for button presses, and an error code beep (see Sound &

Display menu, page 27).

Speed Down and Speed Up Buttons

The Speed Down and Speed Up buttons are used to select the speed mode.

Pressing the Speed Down button selects the next lower speed mode each time

it is pressed, while pressing the Speed Up button selects the next higher speed

mode. The speed modes function like incremental positions on a variable speed

pot.

40-Series Manual, Rev. B

Drive with Actuators (6-button keypad)

This keypad’s six buttons are the standard four (On/Off, Horn, Speed Up,

Speed Down) plus two buttons to activate the two actuator modes. The mode

buttons show one dot (for Mode 1) and two dots (for Mode 2).

Actuator Mode Buttons

With this handcontrol, there’s a button for each mode: Actuator Mode 1 and

Actuator Mode 2. The joystick must be in neutral before pressing an actuator

mode button.

Pressing a mode button causes the LCD chair icon’s outline segments

to illuminate; the ﬁll-in portion of the speciﬁc actuator illuminates to show

which actuator is active (Actuator 1 or Actuator 2). Pressing both Mode buttons

simultaneously causes both actuators to be active. In this example, Actuator 1

is the seatback and Actuator 2 is the seat. For programming, see Seat menu,

page 28.

Drive with Actuators and Lights (8-button Keypad)

This keypad’s eight buttons are the standard four (On/Off, Horn, Speed Up,

Speed Down) plus a Running Lights button, two buttons for the turn indica-

tors (left and right), and an Actuator Mode button.

The hazard lights (i.e., ﬂashing left and right turn signals, front and rear)

are activated by pressing both turn indicator buttons simultaneously. They will

continue to ﬂash even if the system is powered down. To turn off the hazard

lights, press either indicator button again.

Both actuator modes are accessed with the single Mode button.

Running Lights Button

Pressing the Running Lights button turns on the headlamps and any other

running lights on the chair. Pressing the button again turns them off. When

the lights are on, the running lights icon in the LCD is illuminated.

Turn Indicator Buttons

The Left and Right Turn Indicator buttons activate the corresponding turn

indicators. Pressing the turn indicator button again will turn the indicator off.

Also, note that pressing the opposite turn indicator button will cancel the ﬁrst

indicator and activate the new one.

The turn indicator icons in the LCD ﬂash in synchronicity with the

actual turn indicator lights.
