Configurable functions
4.3 Emergency stop
The C4000 has an input for a dual-channel emergency stop button. The emergency stop
monitoring in the device corresponds to stop category 0 in accordance with
EN ISO 13850. You can connect e.g. a door contact or an emergency stop button to the
emergency stop input. The operation of the emergency stop button has the following
effect:
The safety light curtain deactivates the OSSDs.
The C4000 switches to red.
The 7Esegment display on the C4000 indicates .
The emergency stop function deactivates the OSSDs even if the bypass function is acti-
vated.
Take into account the response time of the emergency stop function! The response time of
the safety light curtain on interruption via the emergency stop input is up to 200 ms.
Pay attention to the way in which the emergency stop function works!
The emergency stop button connected to the extension connection on C4000 the affects
only the output signal switching devices (OSSDs) on the C4000.
The C4000 checks after switching on whether an emergency stop function has been
configured and whether a door switch or similar switch is connected. If the configuration
and the electrical connection do not match, the system locks completely (lockEout). The
7Esegment display will then show the error message .
The safety light curtain has an application diagnostic output (ADO) at which the status
of the emergency stop input can be signalled. Details can be found in chapter 4.5
“Application diagnostic output (ADO)”on page 33.
Regularly check the connected emergency stop button or door contact!
By means of organisational measures ensure that the emergency stop button or door
contact is operated once at a specified interval.
This is necessary so that the C4000 can detect any fault that has occurred on the emer-
gency stop button or door switch. The interval is to be defined to suit the specific case
dependant on the application.
Always check whether the output signal switching devices on the light curtain are
deactivated on the operation of the emergency stop button or door switch.
You can configure the emergency stop and whether the input is connected equivalent or
complementary in the CDS on the C4000 (receiver).
The electrical connection of the emergency stop is described in chapter 7.6 “Emergency
stop” on page 79.
