Light Curtain Multi-Function Control Module User Manual
Original instructions
In the Micro 400 specification window it is also possible to specify the resolution and protective height of the Micro 400 light curtain attached to the
MSR42 safety controller. When specified, the Micro 400 reaction time t(LC) will be calculated for this exact type of light curtain. This time is only
valid if exactly this type of Micro 400 safety light curtain is connected to this MSR42 safety controller. The values: number of beams and reaction time
t(LC) will all be printed on the corresponding configuration control document (
Figure 51).
The safety function of the Micro 400 safety light curtain may be overridden for a period of time through use of the “Safety override” function (See
chapter 5.4.8 on page 28) or the muting function ((See chapter 5.6 on page 37)). The override function as well as the muting function, is only allowed
after a thorough safety analysis according to EN 13849-1 and ISO EN 12100 is completed.
5.4.5.1. Blanking
Certain applications in practice require that only part of the Micro 400 protective field needs to be interrupted without the safety outputs activating.
Blanking is activated by selecting the “Blanking active” box in the specification window.
The MSR42 controller offers the following blanking modes. Blanking can be activated either with the Teach-In function (see MSR42 User Manual) or
by downloading a configuration file. The differences between these blanking modes are in detail explained in
chapter 5.7 on page 50.

• Fixed Blanking - X
• Floating Blanking - X
5.4.5.2. Interrupt Ignore Time
For a limited time a light curtain interruption can be ignored. This may be used when parts are moving at a fast speed through the light curtain and need
to be ignored (i.e. will not cause the OSSD outputs to switch) but a person interrupting the light curtain for a time longer than the resulting
configurated time, that person will be detected (i.e. will cause the OSSD outputs to switch) and cause the output to switch off.
The interrupt ignore time is only available in the “Support mode”.
