Initial operation

WARNING
Before the SIMATIC FS400 3RG7845 is put into operation for the first time on a
power-driven production machine, an experienced technician must check the entire
setup and the integration of the optical protective device into the machine
more information, see Chapter 2, Chapter 10 and Chapter 13.2.
Before connecting the supply voltage for the first time and while the transmitters and
receivers are being aligned, it must also be ensured that the outputs of the optical
protective device do not have any effect on the machine. The switching elements that
finally set the dangerous machine in motion must be safely switched off and secured
against restarting.
The same precautionary measures apply after each change in parameter-based
functions of the optical protective device, after repairs or during maintenance work.
Only after it has been determined that the optical protective device functions correctly
can it be integrated into the machine's control circuit!
9.1

Switching on

Make sure that the transmitter and receiver are protected against overcurrent (for fuse
size see Chapter 12.1). There are special requirements for the supply voltage: The
power supply unit must guarantee secure supply isolation, have a load current reserve
of at least 1A and the ability to bridge a power outage for at least 20ms with the use of
receivers with transistor output.

9.1.1 Display sequence with the transmitter

After the device is turned on, "8." appears for a few moments on the transmitter display
followed by an "S" for about 1 second for the self test. The display then switches and
permanently shows the selected transmission channel, "1" or "2".
A "." next to the number indicates when the test input is open. As long as the test input
is open, the transmitter diodes do not deliver any valid light pulses.
WARNING
If the error display is shown on the transmitter (constant display of F or 8), then the
24 V DC supply voltage and wiring should be checked. If the error remains after it is
turned on again, discontinue the setup process immediately and send in the
malfunctioning transmitter to be checked.

9.1.2 Display sequence with receiver / transceiver

After the device is turned on, "8." appears for a few moments on the transmitter display
followed by an "S" for about 1 second for the self test. The display then switches and
permanently shows the selected transmission channel, "1" or "2".
A "." next to the number indicates that multi-scanning (DoubleScan mode, d-scan) has
been selected.
