Reset Type There are two types of reset: “Manual” or “Monitored”. If the “Manual” option is selected, only
the signal transition from “0” to “1” is checked. In the case of the “Monitored” option, the dou-
ble transition from “0” to “1” and back to “0” is checked.

Output Test Enables the selection of clock signals that are to be connected to the contacts of the foot
switch. These additional diagnostics enable the detection of short circuits and cross-circuits
between 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 footswitch is required before the enable. This
test requires the foot switch to be pressed and released in order to activate 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.
With simultaneity /
Simultaneity (ms)
This parameter is only available if the “Double NC” option is selected. In this case, the block
monitors the simultaneous switching of both input channels.
If a signal change does not occur on both input channels within the defined synchronization
time, an enable signal will not be generated at the output. The maximum time interval be-
tween the two input channels can be configured in the range from 10 ms to 7000 ms.
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.
NOTE:
Inputs at a function block must always be used in ascending order.
Example: Input 1 and Input 2 are used for the function block, so Input 3 must be used for
the reset input.
