SG1/4
Selection of the mode of operation of the operate signals TS1 and TS2.
When SG1/4 = 0, the operate signals return to the initial state (= the output relay
drops off), when the measuring signal causing the operation falls below the set start
level.
When SG1/4 = 1, the operate signals remain on (= the output relay operated),
although the measuring signal falls below the set start level. Resetting with command
