- Throttle Type: By default, the Throttle Type of controller 1228-2430 is set as Type “0”. The controller 1228-2430 can be programmed to accept single-ended, wigwag, or inverted wigwag signals from a 5kΩ, 3-wire pot or from a 5V throttle. The throttle input signal type options (Types “0” through “5” in the Throttle Type programming menu) are listed as below:
- 0 = wigwag pot or voltage throttle
- 1 = inverted wigwag pot or voltage throttle
- 2 = single-ended pot; maximum speed = 5kΩ
- 3 = inverted single-ended pot; maximum speed = 0
- 4 = single-ended voltage throttle; maximum speed = 5V
- 5 = inverted single-ended voltage throttle; maximum speed = 0

Features Include:
- Full bridge power MOSFET design, providing
- infinitely variable forward, reverse, drive, and brake control
- silent high frequency operation
- high efficiency
- Complete diagnostics through the CURTIS programmer and a status LED
- Full compliance with all applicable international standards
- Available for single-ended or wigwag 5kΩ potentiometer throttles and 5V throttles (both standard full stroke and restricted range)
- MultiMode™ input selects between two different operating modes, thus allowing optimization of vehicle characteristics for different driving conditions (for example, indoor/outdoor)
- Speed limit input provides linear variable speed limiting when an external speed limit pot is used
- Current limiting in both driving and regenerative braking modes
- Load compensation stabilizes speed on ramps and over obstacles
- Speed scaler eliminates variations in maximum speed that would otherwise result from variations in battery charge levels
- High pedal disable (HPD) function with lockout monitors status of the throttle during turn-on and prevents operation until the throttle has been returned to neutral
- Key-off deceleration function provides a controlled deceleration if the keyswitch is turned off while driving
- “E Stop” provides a faster deceleration for emergency stops
- Seat lift function simplifies the wiring required to implement seat lift in DME scooter applications
- Comprehensive fault detection monitors main contactor, output stage, throttle demand vs. output, etc., and disables the drive functions if any conditions are outside specified limits
- ISO 7176 compliant throttle fault detection circuitry inhibits driving if throttle pot signal goes out of range for any reason
- Missing/shorted brake detection forces neutral in the event of an open or shorted brake circuit
- Anti-rollback/anti-roll-forward function sets brake delay according to speed and direction for improved braking response and minimized rollback on hills, etc.
- Reverse beeper option can be used to drive a low current dc horn when vehicle is in reverse
- “Push” input electrically releases brake for key-on pushing (requires that the vehicle be stopped first)
- “Push-Too-Fast” feature guards against unpowered vehicle runaway by powering up and regulating motor voltage to limit vehicle speed
- Inhibit input disables the controller and puts the vehicle in a safe state during charging, etc.
- Power saver deactivates the main relay after 25 seconds of nonoperation and deactivates the entire controller after the programmed sleep delay has elapsed
- BDI output can be used to provide data to a voltmeter; the BDI output can be “stuffed” (optional) in order to display the battery state of charge during battery charging even while the keyswitch is turned off
- Undervoltage cutback function protects against operation at low battery voltage
- Overvoltage protection shorts the motor and disables driving in the event of excessive battery voltage
- Thermally protected
- Reverse polarity protected (battery input)
- Easily programmable through the CURTIS Model 1313-4331 Handheld Programmer or 1314 PC Programming Station.
