7 Commissioning
Warning!
Before placing the SOLID-2 in operation for the first time on a power-driven production
machine, 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 connecting the supply voltage for the first time and while the transmitter and
receiver are being aligned, it must be ensured that the outputs of the 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 form restarting.
The same precautionary measures apply after every change in operating mode made to
the protective device, after repairs or during maintenace work.
Only after it has been determined that the optical protective device functions are correct it
can be integrated into the machine’s control circuit!
7.1 Startup
Warning!
Without internal start/restart interlock function and the protective field is free the OSSDs
immediately switch to the ON state!
Make certain that the transmitter and receiver are protected against overcurrent (for fuse
size see Chapter 10.1.2). There are special requirements for the supply voltage: The
power supply must have a load current reserve of at least 1 A and the ability to bridge a
power outage for at least 20 ms, and it must guarantee secure mains supply isolation.
7.1.1 Transmitter display
After the power supply is turned on and the selftest is completed, the LEDs indicate the
current operating status (see Chapter 4.1).
Warning!
If the transmitter’s LED1 lights permanently red, the 24V DC supply voltage and the wiring
must 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.
7.1.2 Receiver display
After the receiver is turned on or restarted, the number of the selected transmission
channel appears.
Warning!
In the event of an error or fault, the receiver’s 7-segment display reports it with ”E xx“ or ”F
xx“. The error code in Chapter 9 provides information on whether it is an error (E xx) in
external wiring or an internal device fault (F xx). For internal faults, immediately interrupt
the installation and send in the malfunctioning receiver to be checked.
