Output Test Enables the selection of clock signals that are to be connected to the switch/pushbutton.
These additional diagnostics enable the detection of short circuits and cross-circuits be-
tween the cables. To activate these diagnostics, the clock signals must be configured in the
“Property” window of the relevant function block.
StartUp Test If this option is selected, a function test of the switch/pushbutton is required before the en-
able. This test requires the switch/pushbutton to be activated and deactivated in order to ac-
tivate the “O
UT” output. This check is only required on machine startup.
Filter (ms) This option enables external input signals to be filtered. The filter can be configured with a
value between 3 and 250 ms and helps suppress contact chatter. The length of the filter time
affects the calculation of the response time of the safety function.
Enable Error Out When this parameter is selected, an output (“E
RROR”) is made available which signals that
an error has been detected by the function block.
