6.7 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 page 21) has the same effect as reaching into the protective field. You can
connect the emergency stop input e.g. to a door switch.
The emergency stop can be connected instead of the key-operated switch for bypass, to
the same connections as the key-operated switch 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 C 4000 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 7-segment display will then show the error message ;O'.
$ If you connect an emergency stop to the C 4000, a bypass can no longer be connected,
as it requires the same connections.

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.
