PERMANENT MAGNET
MOTOR SPEED CONTROLLER
MODEL 1228
Features
•
Four quadrant, full bridge solid-state design.
Meets or complies with relevant US
and International Regulations
•
The Curtis Model 1228 motor speed controller is designed to
allow vehicle compliance with the EMC directive 89/336/EEC.
•
Designed to meet ANSI/RESNA WC14/21, ISO 7176-14,
ISO 7176-21 and EN 1284.
•
All software documentation needed to support 510K FDA
filing is available.
Fully Programmable
•
Easily adapted to meet many specific scooter, sweeper
scrubber or light industrial equipment applications.
•
Seat lift function is programmable to allow a single controller
to implement traction and lift functions.
•
Use of an electromagnetic brake is user selectable depending
upon the type of application.
Easy to Install, Set-Up and Diagnose
•
Standard 18-pin Molex Mini-fit Jr. logic connectors makes
wiring simple and inexpensive.
•
Internally protected against damage due to possible mis-
wiring during installation.
•
Can be interfaced with normal or inverted, wigwag (center
off), single ended (speed pot and direction switch), and 0-5V
throttle types, including limited range throttles down to 500Ω
full stroke.
•
Auxiliary B+ and B- terminals and an inhibit input for
connecting to a battery charger.
•
Diagnostic information (throttle faults, low battery, etc.) is
available through dash-mounted LED flash codes and Curtis
handheld programmers.
DesCrIPtION
The Curtis Model 1228 Permanent Magnet Motor Speed
Controller provide smooth and precise operating control,
providing maximum user confidence. Model 1228 fully complies
with European and US regulations and is fully programmable.
aPPLICatION
Ideal for OEM applications on three or four wheeled mobility
aids, such as scooters, and for light industrial equipment such as
sweepers and scrubbers.

Powerful Safety Features
•
Inhibit input prevents driving during charging.
•
Control monitoring functions prevent driving with a defective
throttle or associated wiring.
•
Fault monitoring capability of electromagnetic brake functions
is OEM selectable for individual vehicle requirements.
•
If the keyswitch signal is turned Off while driving, the vehicle
will decelerate normally, rather than stopping abruptly.
•
Where electromagnetic brake is used, push input electrically
releases brake for key-on pushing.
•
If the vehicle is allowed to freewheel, the controller will
automatically limit the maximum speed to a preset low speed.
•
A user supplied external warning beeper can be installed to
alert bystanders when moving in reverse direction.
•
The braking current limit is not decreased with high
temperature, allowing the controller to provide maximum
braking on extended downslopes.
Smooth, Secure Driving Feel
•
The feel of advanced closed-loop control algorithms gives the
operator confidence in the handling, operation and control of
the vehicle, whether it is driving at full speed, on a steep hill
or inching over a curb.
•
Provides superior low speed control by compensating for both
motor and controller losses.
•
The motor current limit is smoothly reduced as the controller
heats up beyond thermal limits, making available the
maximum safe power under all conditions.
•
With the electromagnetic brake selected, the controller varies
the brake operation to provide smooth and secure stops.
•
Provision for a separate speed limit pot allows smooth, linear
adjustment of top speed.
•
Gear softening compensates for slack in worn transaxles to
provide smooth transitions.
Designed and Built for Optimum Reliability,
Convenience and Economy
•
Conservative components rating provides years of trouble-free
operation, and lower warranty costs.
•
Power Saver shuts the controller Off after a programmable
time preserving the battery.
•
MultiMode™ control allows the user to select two entirely
different sets of driving parameters for different driving modes,
such as indoor and outdoor use.
•
Battery Discharge Indicator (BDI) driver provides battery state-
of-charge on a simple, user supplied voltmeter.
•
Appropriate mounting or shielding is required to prevent
exposure of controller electronics when used in wet or high
particulate environments. Environmental rating of controller is
IP40.
