S-DRIVE - PROGRAMMING                   PG DRIVES TECHNOLOGY 
SK76745/10 
Inhibit   The S-Drive will not drive if it is switched on while the throttle is already deflected but once the throttle 
has been returned to its home position it will then allow the scooter to drive.  
Trip   The S-Drive will not drive if it is switched on while the throttle is already deflected and it will record a 
trip in the system log and it will require the scooter to be switched off and on again. 
Setting this parameter to Drive will contravene international mobility vehicle safety legislation. If, 
under  exceptional  circumstances,  the  condition  set  by  Drive  is  required,  it  becomes  the  sole 
responsibility  of  the  scooter  manufacturer.  PGDT  accept  no  liability  for  losses  of  any  kind 
resulting from this parameter being set to Drive. 
4.5  Throttle Reference Test 
If set to “Off” then  all throttle reference checks are disabled to allow the use of a voltage source input. 
4.6  ISO Tests Resistor 
This parameter can be set to On or Off. 
Set to  Off  If  the scooter has  no  ISO-Test Resistor or  the  ISO-Test Resistor  and  Speed Limiting  Potentiometer have been fitted in 
parallel. Both of these conditions comply with ISO7176-14:2008 section 7.2.3.4. 
Set to ON if the scooter has an ISO-Test Resistor and Speed Limiting Potentiometer that have been fitted in series. This condition 
does not comply with ISO7176-14:2008 section 7.2.3.4 
If an ISO-Test resistor is fitted and a series connected speed limiting potentiometer is used, then 
depending  on  the  setting  of  the  potentiometer,  it  may  not  be  possible  to  detect  a  short-circuit 
between the Throttle side of the potentiometer and either of the throttle references. 
5  Battery Parameters 
5.1  Low Battery Flash Level 
This  parameter  sets  the  point  at  which  the  Scooters  TruCharge  battery  gauge  starts  to  flash  slowly  to  warn  of  a  low  battery 
condition. The adjustment range is 1 to 10 in steps of 1, and corresponds to the number of bars shown on the battery gauge. 
Example:    If this value is set to 2, then the flashing will occur when the gauge drops to 2 bars. 
5.2  Cable Resistance 
This sets the value of cable and connector resistance between the controller  and the batteries. The value corresponds to the 
total resistance in both the positive and negative paths. 
You can set this between 10m and 250m in steps of 5m. 
5.3  Calibration Factor 
This  allows  further  fine  calibration  of  the  TruCharge  battery  gauge.  This  is  normally  set  at  the  factory  and  should  not  need 
adjustment. 
Please contact PGDT if you are considering altering this factor. 
5.4  Low Battery Alarm 
This parameter sets whether the S-Drive will give an audible alarm to signal a low battery condition. The point at which the alarm 
will sound corresponds to the Low Battery Flash Level setting.
