Special MSR42 control module features -- for existing customers.
Interrupt Ignore Time
This function is not included in the standard version.
A limited time a light curtain interruption will be ignored. This may be
used when parts move through the light curtain at high speed and the
safety output should not switch, but yet a person moving through the
light curtain should be detected and cause the safety output to switch off.
Activating this operating mode, a limited time a light curtain
interruption will be ignored. This may be used when parts may move at a
fast speed through the light curtain without interrupting, but a human
will interrupt the light curtain at time longer than the configurated time.
The Interrupt Ignore Time function has to be activated by the MSR42
“Configuration & Diagnostic Tool” software and downloaded to the
MSR42 control module with help of the USB/optical interface (445L-
AF6150)

Interrupt Ignore Time will increase the
response time. The response time is given
in the corresponding configuration
control document. Recalculate the safety
distance.
