A
SSEMBLY
After assembling the module group and making all connections, the next part
of the commissioning process is to perform a partial functionality check on the
SIWAREX FTC and all 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?
•
Have all tools, materials or components that do not belong to the S7 or
SIWAREX FTC been removed from the profile rail and the module group?
Turn on power supply on.
Proper initialization of the SIWAREX FTC in the SIMATIC can only be
guaranteed if:
- the S7-CPU (with decentralized connection with IM 153-1) and the
SIWAREX FTC are switched on at the same time
or
- the SIWAREX FTC first.
After applying the 24V supply voltage and a short initialization phase (internal
tests are indicated by LED running sequence), the SIWAREX FTC goes into
operating status. The following LEDs must have the status that is indicated
below if the unit is running correctly:
LED (EXC)
