TESTING the system
After validating and uploading the project to the 485EPB 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 eloProg to
check that the status of the outputs actually changes.
The following example is helpful for understanding the TEST procedure.
Figure 37
(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.
