Electrical installation
7.5 Reset button
In the protective operation with internal restart interlock (see page 28) the operator must
first press the reset button before restarting.
Select the correct installation site for the reset button!
Install the reset button outside the hazardous area such that it cannot be operated from
inside the hazardous area. When operating the reset button, the operator must have full
visual command of the hazardous area.
Device configuration after replacement!
If you replace a safety light curtain with deactivated reset function with a replacement
device, the reset function must again be deactivated via the software. It is not sufficient to
make the electrical connections, because new devices are supplied ex factory always with
activated reset function.
