Filter (ms)
: This is used to filter the signals coming from the external contacts. 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.
Object description
: This allows a description of the component's function to be entered. The text is
displayed in the top part of the symbol.
SWITCH
SWITCH function block verifies the input status of a
pushbutton or switch (NOT SAFETY SWITCHES). If
the pushbutton is pressed the output is 1 (TRUE).
Otherwise, the output is 0 (FALSE).
Parameters
Enabled reset
: If selected this enables the request to
reset each time the area protected by the safety light
curtain is occupied. Otherwise, enabling of the output
directly follows the input conditions.
There are two types of reset: Manual and Monitored.
When Manual is selected the system only verifies the
signal's transition from 0 to 1. If Monitored is selected
the double transition from 0 to 1 and then back to 0 is
verified
.
Î
WARNING: If the Enabled Reset is active, a consecutive Input has to be used. Example:
Input 1 is used for the functional block, then Input 2 has to be used for the Reset Input.
Output test
: This is used to select which test output signals are to be sent to the emergency stop
(mushroom pushbutton). This additional test makes it possible to detect and manage any short-
circuits between the lines. There is a choice of 4 possible test output signals, Test Output 1 ÷ Test
Output 4.
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 then 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).
