The MSR41 base module has two status outputs (“Info1” and “Info2”).
A description of these outputs is given below.
The following table shows the logic of the two status outputs. The state
of the status outputs will also be displayed through LED, visible on the
front side of the main module.

General
• The response time of a MSR41 base module depends on the
connected GuradShield Micro400 Light Curtain length and
resolution.
• The response time for the MSR41 base module [t(totLCOSSD)]
with respect to the Micro400 light curtain is the sum of the base
module response time t(C) + the response time of the light curtain
t(LC):
t(totLCOSSD)= t(C) + t(LC)
• The response time for the MSR45E expander module (relay safety
output) [t(totLCEXT)] with respect to the Micro400 light
curtain is the sum of the base module response time
t(totLCOSSD) + the response time of the expander module
t(em):
t(totLCEXT)= t(totLCOSSD) + t(em)
=t(C) + t(LC) + t(em)
The total response time of a system is the sum of each response time:

These outputs may not perform any
safety relevant functions. They serve only
to communicate the status to a machine
controller.
