Testing The System - Reer MOSAIC M1 Installation And Use Manual

TESTING the system


After validating and uploading the project to the M1/M1S and connecting all the safety devices,
you must test the system to verify its correct operation.
This is done by forcing a change of status for each safety device connected to the MOSAIC to check
that the status of the outputs actually changes.
The following example is helpful for understanding the TEST procedure.
(t1) In the normal operating condition (E-GATE closed) Input1 is closed, Input2 is open and the
output of the E-GATE block is set to high logic level; in this mode the safety outputs
(OSSD1/2) are active and the power supply to the relative terminals is 24VDC.
(t2) When the E-GATE is physically opened, the condition of the inputs and thus of the outputs
of the E-GATE block will change: (OUT= 0VDC--->24VDC); the condition of the
OSSD1-OSSD2 safety outputs will change from 24VDC to 0VDC. If this change is detected
the mobile E-GATE is connected correctly.

For the correct installation of each external sensor/component refer to their installation
manual.

This test must be performed for each safety component in the project.
