The MSR42 base module has two status outputs (“Info1” and “Info2”).
The logic of these two outputs depends on the configuration. A
description of these outputs is given in the configuration control
document. The following table shows the logic of the two status outputs
for the basic configuration. 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 MSR42 main module depends on the
configuration.
The relevant maximum response times for the MSR42 control module,
with respect to a specific Micro 400 light curtain and MSR45E expander
module, as well as a specific safety component may be calculated using
the formulas below.
The response time may be increased if a stop delay time t(delay) is
configured for a safety component or a Micro 400 light curtain. During
this delay, all start impulses are ignored. The safety outputs will switch
off at the end of this delay period.
The controller is shipped with the double scan filter. Single scan filter can
be selected to reduce the response time. The relevant times may be found
in the corresponding configuration control document (e.g. see
configuration software manual).
If authorized personnel reconfigure the
control module using the USB/optical
interface, then depending on the
configuration the response time or the
stop delay time t(delay) may increase. So
it is very important that after every new
configuration.
a. the configuration change label
(page 13) is placed on the control
module and
b. the new response time is confirmed to
be within the limits given by the risk
analysis of the machine and
c. All relevant data of the actual
configuration are always described in
the actual configuration control
document for that controller. Make
sure that the actual document is
always stored near to the control unit.
d. Using the blanking mode, the
resolution of the Micro 400 will be
reduced. Label the Micro 400 with the
new resolution. A label is supplied
with the Micro 400 light curtain
mounting kit.

These outputs may not perform any
safety relevant functions. They are
diagnostic outputs which provide status
to a machine controller.
