English
FOOTSWITCH
Using the FOOTSWITCH function block the in-
put status of a safety footswitch is checked. If
the footswitch is not pressed, the OUTPUT out-
put is "0" (FALSE), otherwise the OUTPUT out-
put is "1" (TRUE).
Parameters
Input Type:
- Single NC – makes it possible to connect
footswitches with one normally closed con-
tact
- Single NO – makes it possible to connect
footswitches with one normally open contact
- Double NC – makes it possible to connect
footswitches with two normally closed con-
tacts
- Double NC/NO – makes it possible to con-
nect footswitches with one normally open
contact and one normally closed contact.

Connect inactive input (OUTPUT output is "0" (FALSE)) as follows:
- NO contact to terminal that has been assigned to the input IN1.
- NC contact to terminal that has been assigned to the input IN2.
Manual Reset: If selected, a reset can be requested on every activation of the safety
footswitch. Otherwise the activation of the output will correspond directly to the input
conditions.
There are two types of reset: "Manual" and "Monitored". On the selection of the manual
reset, the system only checks the signal transition from 0 to 1. With the monitored reset
the double transition from 0 to 1 and then back to 0 is checked.
