NSTALLATION
SK75326/6
The controller can be programmed to give either a continuous alarm or a pulsed
alarm. This can be selected by programming, (see Programming and Diagnostic
Technical Manual).
6.6 Status Indicator
This output controls either a PGDT TruCharge type status indicator or a single bulb (or
LED) type status indicator.
If you are using a bulb, this must be 12V with a maximum rating of 600mW: the bulb
can be connected directly between pin 11 and 0V. If you are using an LED, it is
connected between the same points but you must provide a series connected current
limiting resistor. For details of connection to a TruCharge type status indicator, refer to
the relevant data sheet.
6.7 Reverse Switch
Pin 2 is a connection to a reverse switch. This is required to select reverse drive if the
controller is being used with a single-ended throttle configuration.
The polarity of the input is programmable and can be changed using the Invert
Throttle Polarity command
(see Programming and Diagnostic Technical Manual).
With Invert Throttle set to NO, the drive will be in reverse if pin 2 is connected to 0V.
With Invert Throttle set to YES, the drive will be forwards if pin 2 is connected to 0V.
6.8 Slow/Fast Switch
Pin 9 is an input which can be used to limit the forward and reverse speeds, the
forward and reverse acceleration and the forward and reverse deceleration of the
scooter. Typical uses are: to select between indoor or outdoor use or, as is a requirement
in certain countries, to limit the scooter’s speed while driving on the sidewalk.
If pin 9 is connected to 0V the controller will drive using the programmed slow speeds
and rates (see Programming and Diagnostic Technical Manual).
6.9 Freewheel
Pin 3 is an input which can be used to release the solenoid brake so that the scooter
can be freewheeled. To release the solenoid brake pin 3 should be connected to 0V.
As a safety feature, whilst this input is active the scooter’s freewheel speed is limited to
75% of the scooter’s maximum driving speed.
Depending on the scooter specification, the freewheel switch can be fitted in one of
two positions: firstly, on the tiller (or at another convenient point) so it can be operated
directly by the person wishing to push the scooter, or, secondly, in a position such that
it is operated by the solenoid brake manual disengagement mechanism. If the
freewheel switch is fitted on the tiller, PGDT recommend the switch must be a momentary
operation type.
If the freewheel switch is not operated by the solenoid brake manual disengagement
mechanism, then an additional micro-switch which opens when the brake is
disengaged should be fitted. This micro-switch should be connected in series with the
solenoid brake. This interlock is to meet the requirements of ISO7176-14 which states
that the scooter should not be able to drive if the solenoid brake is not engaged.
