It uses four steps to lead to a functioning application in which you count the switching operations of a contact and become familiar with and test the basic functions of the hardware and software of your FM 350-1. The references to the manual are intended to give you an initial overview of the information in the manual. The references refer to the “FM 350-1 Function Module” manual with the number A5E00073040-01.
