Startup
Warning!
Before starting up the SOLID-4 on a power-driven production machine for the first time, an
experienced and commissioned person with suitable training must check the entire setup
and the integration of the opto-electronic protective device into the machine control system.
Before switching on 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 from
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!
8.1
Switching on
Warning!
Without internal start/restart interlock function and with free protective field the OSSDs
immediately switch to the ON state!
Make sure that the transmitter and receiver are protected against overcurrent (for fuse size
see Chapter 7.2). There are special requirements for the supply voltage: The power supply
must guarantee secure mains supply isolation, have a load current reserve of at least
250 mA and be able to bridge a power outage for at least 20 ms.
8.1.1
Display sequence with SD4T Transmitter
After the power supply is turned on and the self-test is completed, the LEDs indicate the
current operating status (see Chapter 5.1).
Warning!
If the transmitter signals with error display (LED1 lights permanently red/LED2 any display),
the 24 V DC supply voltage and the wiring must be checked. If the error remains after it is
turned on again, stop the startup process immediately and send in the defective transmitter
to be checked.
