CONTROLLER WIRING: Model-Specific Requirements
e 1229 has four features that require model-specic controller wiring. ese are the Push (mode),
Push-Too-Fast, Key-O Decel (deceleration), and the Status Beacon options. To enable these features
and prevent controller damage, follow the wiring specifications and examples described and
illustrated in this Chapter.
Push (mode)
For pushing a light vehicle with the keyswitch on, but not driving the vehicle with the motor, use the
push input (switch) option. is is for vehicles without a mechanical brake release. To enter the Push
mode, the controller must be ON and the vehicle stopped. en switch the Push input to KSI voltage.
e push input electrically releases the electromagnetic brake, thus precluding the necessity for a
mechanical brake release. An active push input inhibits the controller’s drive functions until de-
activated (KSI voltage removed from the input). e Push feature uses the IO Map function 90-Push.
Pushing a vehicle
e option of electrically releasing the brake is convenient when, for example, it is appropriate for
an attendant to manually-push a mobility aid scooter. is safeguards against conditions in which
electromagnetic brake cannot be re-engaged. e push feature inhibits the controller’s drive function,
so the motor will freely spin (no drag).
Pushing the vehicle too quickly will indicate a runaway or other abnormal condition. To address
this, specic controller models will automatically turn on and limit the speed of the vehicle. is is
the Push-Too-Fast feature. Otherwise, releasing the push input will engage the EM Brake, which is
appropriate for low-weight walking speed applications.
Push-Too-Fast
e Push-Too-Fast feature adds the ability to limit the maximum speed at which the vehicle can be
pushed, thus safeguarding against unpowered vehicle runaway with the brake mechanically released.
e controller, even if it is o and there are no batteries in the system, will detect the motor voltage
created by the moving vehicle. When the motor voltage becomes high enough, indicating signicant
vehicle speed, the controller logic will power up and turn on the MOSFET power sections to short
the motor and limit the speed of the vehicle. To do this, specic wiring connections and controllers
are required.
When the key is o, the voltage at the motor terminals when the Push-Too-Fast feature engages is
16V ±1V. e controller’s capacitor bank (VCAP = B+ terminal) will be 1 - 2 Volts below this value.
When the motor voltage increases to the Push-Too-Fast limit, the controller will short the motor in
a controlled manner.
Activating the Push Enable input resets the High Pedal Disable (HPD)*. At power-up, the controller
ignores an active Push Input until it is cycled (released and re-engaged). To enter the push-enabled
mode, the vehicle must also be in neutral.
* HPD prevents vehicle movement when the throttle is active before the keyswitch or the interlock at asserted. HPD prevents
vehicle movement at key-on if there is a broken or improperly configured throttle. See the HPD parameter settings.
