Original instructions
Figure 35: window "Interrupt Ignore time"
Hint:
The light curtain parameters: resolution and protective height must be defined before the interrupt ignore time function can be activated (support
mode only)
Important safety advice:
• Interrupt Ignore Time will increase the response time. Recalculate the safety distance.
5.4.5.3. Double Scan Filter
The MSR42 controller scans all light curtain optical elements two times to evaluate the state of the light curtain. This function is very robust against
electrical or optical disturbances. Deactivating this filter results in a faster response time.
Warning: Important safety advice
An active double scan filter results in a longer response time. Consider the exact response time when evaluating the safety distance. The configuration
control document (
Figure 51) shows the configured response time, by default with double scan filter active.
Hint: Fast response time
While the connected Micro 400 light curtain is undefined by default, the response time printed on the Micro 400 label is valid. However, the real
response time may be faster. Entering the Micro 400 resolution and protective height or the total number of beams (See
Figure 33 Section ‘Light curtain
parameters’) the real response time for this specified Micro 400 and this respective configuration will be shown on the control configuration document.
Warning: Important safety advice,
Response time of cascaded Micro 400 light curtains
When connecting multiple Micro 400 safety light curtain systems into one cascaded system (see also Micro400 user manual), the total length of the
protective field (respectively the sum of all light curtain beams) have to be considered for response time calculations!
5.4.6. One Device (2 NC)
In the specification window “1 Device (2 NC)” ( Figure 36), the corresponding start mode, and if required the stop delay function may be configured.
The stop delay time itself is defined in the “Safety Output OSSD” window (See chapter 5.4.12 on page 31).
