WARNING: If the Manual Reset is active, a consecutive Input have to be used.
Example : Input 1 and Input 2 are used for the fuctional block, then Input 3 have to
be used for the Reset Input.
OUT TEST signals cannot be used in case of safety static output ESPE because the control
is carried out from the ESPE.
Test at start-up: If selected this enables the test at start-up of the safety light curtain.
This test is performed by occupying and clearing the area protected by the safety light
curtain to run a complete function test and enable the output. This test is only requested
at machine start-up (when the unit is switched on).
Filter (ms): This is used to filter the signals coming from the safety light curtain. The filter
can be configured to between 3 and 250 ms and eliminates any bouncing on the
contacts. The length of the filter affects the calculation of the unit's total response time.
Simultaneity (ms): always active. Determines that maximum permissible time (msec)
between switching of the various signals from the external contacts of the device.
Enable Error Out: If selected reports a fault detected by the function block.
Item description: This allows a description of the component's function to be entered. The
text is displayed in the top part of the symbol.
The FOOTSWITCH function block verifies the
status of the inputs of a safety pedal device. If
the pedal is not pressed the output is 0
(FALSE). Otherwise the output is 1 (TRUE).
Parameters
Input type:
- Single NC – Allows connection of pedals
with one NC contact
- Single NO – Allows connection of pedals
with one NO contact.
- Double NC – Allows connection of pedals
with two NC contacts
- Double NC/NO – Allows connection of
pedals with one NO contact and one NC.
With inactive input (block with Output FALSE), connect:
