Notes
• For teach-in a reset button must be connected to the
SafeShield safety light curtain (see “Reset Button” on
page 28).
• If you connect a teach-in switch to the SafeShield safety
light curtain, then you can no longer use the emergency
stop function in the SafeShield safety light curtain.
• If you use a SafeShield function module then you can also
connect the teach-in key-operated switch to the
switching amplifier.
➢ Ensure that only authorized persons have access to the
teach-in key.

Emergency Stop
The emergency stop input has two channels. The emergency stop
monitoring in the device corresponds to stop category 0 in
accordance with EN 418. Switch off at the emergency stop input
(see “Emergency Stop” on page 29) has the same effect as reaching
into the protective field. You can connect the emergency stop input
e.g. to a door switch.

You can design the two-channel button as equivalent (N/C, N/C) or
complementary (N/O, N/C). You must configure the SafeShield
safety light curtain as appropriate with the aid of the SCD. If the
configuration and the electrical connection do not match, the
system locks completely (lock-out). The 7-segment display will then
show the error message .

ATTENTION: Device configuration
after replacement!
If you replace a safety light curtain with the
emergency stop function active, then you
must transfer the configuration to the device
again. It is not sufficient to make the
electrical connections, because new devices
are supplied ex factory with deactivated
Emergency stop function.
