Switching the SPtM, SPI and MINT applications 
 
The default application of IG/IS-NT-Combi is the SPtM application. The SPI and MINT applications can be 
activated during the “emergency manual” state only. 
 
To  change  the  application  from  the  SPtM  to  SPI  application  close  both  BI:  Emerg.  manual  and  BI:  SPI 
Enable and after that open BI: Emerg. manual only. The controller is set to SPI application now. 
 
To  change  the  application  from  the  SPtM  to  MINT  application  close  both  BI:  Emerg.  manual  and  BI: 
MultipleEnable and after that open BI: Emerg. manual only. The controller is set to MINT application now. 
 
To change the  application from  either  SPI  or  MINT to  the  default SPtM application  close the  BI:  Emerg. 
manual and open either BI: SPI Enable or BI: MultipleEnable. After that open the BI: Emerg. manual. The 
controller is set to SPtM application now.
