Example 2 two hand button: electrical circuit
diagram in easySafety
The TH01I input coils of the function block are associated
directly with the device terminals IS10 to IS13, the enable
contact TH01QS switches the device outputs QS1 and QS2
directly.
The enable parameter and the parameter display stay in the
default setting, the evaluation of the two hand button is
switched to 2-channel (2CH).
The test signals for cross-circuit monitoring are assigned to
the corresponding device inputs in the TEST SIGNALSmenu.
The signal diagram of the function block for this application
shows the dependence of the enable contact TH01QS on the
status of coil TH01I1 and TH01I4:
