Introduction
Visual check
Connect
SIWAREX FTA
with 24 V supply
LED check on the
SIWAREX FTA

At this point in the commissioning procedure, after assembling the module
group and making all connections, you should perform a partial functionality
test for the SIWAREX FTA and the connected components.
The individual steps for partial testing are to be performed in the following
sequence:
Check all previously performed steps for proper execution, i.e.:
•
Is there any external damage to the module group?
•
Are the modules situated in the proper positions?
•
Are all fastening screws properly tightened?
•
Are all connecting cables properly connected and fastened tightly?
•
Is the frontal connection made properly?
•
Is the shielding properly attached to the shielding conductor for all
corresponding cables?
•
Is the profile rail connected to the ground conductor?
•
Are all tools, materials or components that do not belong to the S7
or SIWAREX FTA removed from the profile rail and the module group?
Switch power supply on.
Proper initialisation of the SIWAREX FTA in the SIMATIC can only be
guaranteed if:
- the S7 SPU (with decentralised connection with IM 153-1) and the
SIWAREX FTA are switched on at the same time
or
- the SIWAREX FTA is switched on first
After attaching the 24V supply voltage and a short initialisation phase
(internal testing is indicated by LED running pattern), the SIWAREX FTA
goes into operational status. The following LEDs must have the status that is
indicated below if the unit is running correctly:
LED (EXC)
-->
LED (SEN)
-->
LED (SF)
-->
ON status
ON status
OFF status
