Configurable functions
This chapter describes the functions on the M4000 multiple light beam safety device that
can be set via software. Some of the functions can be combined.
WARNING
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 9.3 on page 100).
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

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 situated outside the hazard-
ous area.
Do not confuse the restart interlock with the start interlock on the machine. The start
interlock prevents the machine starting after switching on. The restart interlock prevents
the machine starting again after an error or an interruption in the light path.
You can prevent the machine restarting in two ways:
With the internal restart interlock of the M4000:
The M4000 controls the restart.
With the restart interlock of the machine (external):
The M4000 has no control over the restart.
