S-DRIVE - INSTALLATION                    PG DRIVES TECHNOLOGY 
SK76745/10 
The parameter Speed Limit Pot. Enabled should be set to On. 
To comply with ISO7176-14: 2008 section 7.2.3.4 PGDT recommends speed limiting potentiometers 
be fitted in Parallel only. 
4.3  ISO-Test Resistor Configuration 
If a Speed Limit Pot. is fitted in parallel, or not fitted at all, then it is not necessary to fit an ISO-Test resistor in order to comply with 
ISO7176-14:2008 section 7.2.3.4. 
Fitting a Speed Limit Pot and ISO-Test Resistor in series does NOT comply with ISO7176-14:2008 
section 7.2.3.4 
To program the S-Drive to suit the scooter installation, Refer to Chapter 3. 
4.4  On/Off Switch 
Pin 5 is the battery positive supply to the controller from the on/off switch. The maximum power consumption of the controller via 
this connection will not exceed 1A.  
Large capacitances  connected between pin 5 and  0V  may affect the  ability  of  the S-drive to switch  on  or  off  reliably.  If  it  is 
desired to connect a large capacitance, for example to damp a battery gauge voltmeter or to suppress a horn sounder, then 
connection should be made between battery 24V (pin 7) and 0V.  
It is the responsibility of the scooter manufacturer to test the effectiveness of the On/Off switch. 
4.5  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 PGDT TruCharge indicator, the data connection must be to pin 10. 
The maximum  current  rating  of the output  is 50mA,  you must ensure  that  the indicator does  not  draw  more  current  than  this 
value.  
 
If  you  are  using  a  bulb,  the  bulb  can  be  connected  directly  between pin  10  and  0V  (Highside)  or  pin  10  and  switched  24V 
(Lowside). The bulb must be 12V with a maximum rating of 600mW when connected Highside and 24V with a maximum rating of 
600mW when connected Lowside.  
If  you  are  using  an  LED,  it  is  connected  between  the  same  points  but  you  must  provide  a  series  connected  current  limiting 
resistor.
