4 Configurable functions
This chapter describes the functions of the safety light curtain which are selectable via
software C4000. Some of the functions can be combined. An overview of the possible
combinations and possible limitation is given in chapter 4.11 “Functions that cannot be
c
ombined” on page 39.
The Clone Plug configuration tool is available for transferring already saved and tested
configurations from one C4000 to identical C4000 safety light curtains (see 12.7
“Accessories” on page 111). In a Clone Plug, you can successively save the configuration
of the sender and of the receiver. You can use the saved configuration either as a backup
or for cloning.
Test the protective device after any changes!
Changes to the configuration of the devices can degrade the protective function. After
every change to the configuration you must therefore check the effectiveness of the
protective device (see section 7.3 on page 64).
The person who makes the change is also responsible for the correct protective function of
the device. When making configuration changes, please always use the password hierar-
chy provided by SICK to ensure that only authorised persons make changes to the configu-
ration. The SICK service team is available to provide assistance if required.
When starting to configure the device, you may save an application name with a maximum
of 22 characters. Use this function as a “memory jog”, e.g. to describe the application of
the current device configuration. Device symbol C4000 Host (receiver) or C4000 Host
(sender), context menu Configuration draft, Edit, file card General, option Application
name.
4.1 Restart interlock
The dangerous state of the machine () is interrupted if the light path is broken (), and
is not re-enabled ( ) until the operator presses the reset button.
Do not confuse the restart interlock with the starting interlock on the machine. The start
interlock prevents the machine starting at switch on. The restart interlock prevents the
machine starting again after an error or an interruption in the light path.
The restart interlock can be implemented in two different ways:
With the internal restart interlock of the C4000:
The C4000 controls the restart.
With the restart interlock of the machine (external):
The C4000 has no control over the restart.
