Introduction
The MSR4x is a family of extremely compact safety controller modules.
The main controlling module allows for the connection and control of
the compact Allen-Bradley GuardShield Micro400 safety light curtain.
Depending on the configuration, other safety components can also be
connected and monitored simultaneously.

Customer Configurations
The configuration of a MSR42 base module may very easily be adapted
to the customer requirements of an individual application with the help
of the USB/optical interface and the Allen-Bradley Guardmaster
Software “Configuration & Diagnostic Tool”. More information can be
found in the Software Technical Manual. The software is capable of
generating a configuration control document which lists configurations
and specifications of the controller and light curtain (Figure 16).
• Automatic storage facilities
Application restrictions
MSR42 base modules are not intended for application in explosive (EX)
or in radioactive environments.
Dimensions
The dimensions of the MSR42 housing are illustrated in Figure 2.
Figure 2: Base module dimensions are the same for expansion modules
Wiring diagrams
The resolution and the response time may
increase due downloading other
configuration settings for the Micro 400
and other safety sensors connected to
MSR42. Consider the relevant resolution
and the maximum response time when
evaluating the safety distance. See
Chapter 7. 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.
Applications
Typical applications
Typical MSR42 base module applications are:
•Presses
• Robotic cells with automatic insertion
•Assembly lines
• Indexing tables
• Conveyor systems
Basic configuration
The following figures show the connection possibilities for the MSR42
base module with the basic configuration. The logic of this basic version
is exemplified in the accompanying configuration control document:

Customer Configurations
The configuration of a MSR42 control module is set up via of the USB/
optical interface and the Allen-Bradley GuardShield Software
“Configuration & Diagnostic Tool”. The configuration procedure can be
found in the Technical Description Manual. Configuration details can be
found in the specific configuration control document for the MSR42.
The following features may be selected:
•Stop delay
• Single scan for faster response times
• Configuring GPIO terminals for one or two safety inputs
• Configuring GPIO terminals for E-Stop or door switch
•Safety Override
•Muting
•Blanking
A new configuration has to be downloaded to the MSR42 controller by
authorized personnel using the USB/optical interface (445L-AF6150).

Light Curtain Multi-Function Control Module User 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.
Status outputs
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.
Terminal (LED) Output "high" (+24 V) Output "low" (0 V)
Info1 (LED) Start ok (green) No start possible (red)
Info2 (LED) System okay (green) Error (Lock out) (red)

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

Response time
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 controlle r is sh ipped with th e double scan fi lter. Single s can filter ca n
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).
