Electrical installation

6.7 Reset button

n the protective operation mode with internal restart interlock (see page 20) 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.

You can reduce the wiring effort by connecting the reset button directly to the spare exten-

sion connection on the receiver. In a cascaded system this is the extension connection on

the last receiver.

Device configuration after replacement!

If you replace a safety light curtain with active reset function with a replacement unit, the

reset function must again be activated via the software. It is not sufficient to make the

electrical connections, because new devices are supplied ex factory with deactivated reset

function.

Connection of a signal lamp to the output Reset required

Pin 8 of the extension connection is the output “Reset required” (24 V). You can connect a

signal lamp here to indicate this status. The output has a frequency of 1 Hz.
