    4.2.2.1 Broken Wire Detection Requirement for type approved installations. Each switch shall have a 10 kΩ resistor connected across. The 10 kΩ resistors shall be connected directly at the switch, and not at the SDU. Switches shall be normally open (NO), and shall close to indicate engine shutdown. 4.2.2.2 Short Circuit Detection Each switch shall have a 10 kΩ...

  • Page 9: Pickup Channel

    4.2.4 Pickup Channel The SDU can operate with a magnetic or active pickup source. In case of an active pickup source, the SDU needs to be configured properly. Connect the pickup to terminals 4 and 5, with shield to terminal 3. Make sure the cable shield is connected at the SDU side and not at the pickup side.
