6.9 Emergency stop
T
he emergency stop input has two channels. The emergency stop monitoring in the device
corresponds to stop category 0 in accordance with EN ISO 13850. Switch off at the
emergency stop input (see page 23) has the same effect as reaching into the protective
f
ield. You can connect the emergency stop input e.g. to a door switch.
The emergency stop signal can be connected to the same connections as the key-operated
pushbutton for bypass instead of the key-operated pushbutton for bypass.
You can design the two-channel button as equivalent (N/C, N/C) or complementary
(N/O,
N/C). You must configure the C4000 as appropriate with the aid of the CDS. If the
configuration and the electrical connection do not match, the system locks completely
(lock-out). The 7Csegment display will then show the error message .
If you connect an emergency stop signal to the C4000, then it is no longer possible to
connect a key-operated pushbutton for bypass, as the pushbutton uses the same
connections.

General, option Emergency stop active.
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 con-
nections, because new devices are supplied ex factory with deactivated Emergency stop
function.
