Fig. 5–5: Single-channel control sequence via KE
Explanation on the signals
1
Signal "high" (signal "on")
0 Signal "low" (signal "off")
Subsequent switching conditions are linked by logical AND, unless indicated otherwise.
The following flow chart provides an overview of the sequence of the individual control signals and the
subsequent switching conditions between the beginning and end of a tightening process of a tightening
controller with individual control (control not via communication unit). This may be a compact system (CS)
or an SE control unit controlled via 24 V. Use of the individual PLC signals depends on the individual case
of application, e.g. Setting of Prg0...7.
