Functional test

The voltage supply and the connection to the system bus must be tested on completion of the elec-
trical connection.
Voltage supply
Signal
LED "P" (Power, green) is lit
LED "P" (Power, green) is not lit
Connection to system bus
The "Bus In" input must be connected to the "Bus Out" output of an upstream router module.
NOTE!
Under certain circumstances, swapped connecting cables for Bus In, Bus Out1, and Bus Out2 are not
detected by the system. The system then starts with reversed strands.
To avoid this situation, the connecting cables for Bus In, Bus Out1, and Bus Out2 must be labeled clearly.
If necessary, the strands can be identified through the serial number of the modules.
Startup
The check described above completes the process of installation and electrical connection. For the start-
up, the router module is integrated into the system through the definition of the hardware arrangement
in the setup program. The router module itself does not need to be configured (see operating manual of
the central processing unit).
3 Electrical connection
Meaning
The router module is supplied with voltage.
The router module is not supplied with voltage or
there is a problem with the electrical function of the
LED.
Remedy:
• Check voltage supply at the "+24V" and "GND"
terminals of the router module.
• Check power supply unit and connection be-
tween the power supply unit and the router
module.
If the "P" (Power) LED does not light up despite a
voltage supply being present, the module insert or
– if the bus board inside the housing is faulty – the
entire router module must be replaced.
