WARNING: If the Manual Reset is active, a consecutive Input have to be used.
Example : Input 1 is used for the fuctional block, then Input 2 have to be used for
the Reset Input.
Output test: This is used to select which test output signals are to be sent to the
sensor. This additional control permits detection and management of any short-circuits
between the lines. To enable this control, the test output signals must be configured
(amongst those available).
Test at start-up: If selected this enables the test at start-up of the sensor. This test is
performed by occupying and clearing the area protected by the sensor 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 sensor. 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.
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 S-MAT function block verifies the status of
the inputs of a safety mat. If a person stands
on the mat the output is 0 (FALSE). Otherwise,
with the mat clear, the output is 1 (TRUE).
Parameters
Manual reset: If selected this enables the
request to reset each time the mobile
guard/safety gate is activated. 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.
