MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC8540780 • 25th June 2012 • Rev.15 69EnglishS-MAT (safety mat)The S-MAT function block verifies the status ofthe inputs of a safety mat. If a person standson the mat the output is 0 (FALSE). Otherwise,with the mat clear, the output is 1 (TRUE).ParametersManual reset: If selected this enables therequest to reset each time the mobileguard/safety gate is activated. Otherwise,enabling of the output directly follows theinput conditions.There are two types of reset: Manual andMonitored. When Manual is selected the systemonly verifies the signal's transition from 0 to 1.If Monitored is selected the double transitionfrom 0 to 1 and then back to 0 is verified .Î If the Manual Reset is active, a consecutive Input have to be used. Example : Input 1and Input 2 are used for the fuctional block, then Input 3 have to be used for theReset Input.Î Each output OUT TEST can be connected to only one input S-MAT (it is not allowedparallel connection of 2 inputs).Î The function block S-MAT can not be used with 2-wire components and terminationresistance.Output test: This is used to select which test output signals are to be sent to the s-matcontact. This additional control permits detection and management of any short-circuitsbetween the lines. To enable this control, the test output signals must be configured(amongst those available). Test signals are mandatory.Test at start-up: If selected this enables the test at start-up of the external component.This test is performed by pressing and releasing the safety mat to run a completefunction test and enable the output. This test is only requested at machine start-up (whenthe unit is switched on).Filter (ms): This is used to filter the signals coming from the external contacts. The filtercan be configured to between 3 and 250 ms and eliminates any bouncing on thecontacts. 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.
