Introduction
The Rockwell Automation Guardmaster muting controller box is a pre-wired enclosure using an MSR42 multi-function control module as
the muting control module. This muting enclosure has pre-wired M12 quick-disconnect connectors to accommodate the connection of
the Safe2/Safe4, Micro 400, or GuardShield POC and PAC safety light curtains. It also has pre-wired quick-disconnect connectors to
connect up to four Rockwell 42EF, 42JS, or other Rockwell sensors as well as an M8 quick-disconnect connector for a muting lamp.
The Rockwell Automation Guardmaster muting box is supplied with flat brackets to mount this enclosure to a solid, flat surface or to the
Rockwell Automation aluminum two meter floor mounting stand (445L-AMSTD2M). This floor mounting stand is designed for one or two
500 mm aluminum posts (445L-AMSTDMUT) to be cantilevered to each side of the vertical floor stand allowing for two or four muting
sensors to be connected and positioned along their length. This mounting stand with one cantilever post is best for two sensor “L” type
muting applications and a two cantilever post configuration is best suited for two or four sensor “T” type muting. Both “L” and “T”
configurations are best suited for conveyorized muting applications.
The MSR42 multi-function safety control module allows up to four sensor muting, if the Micro 400 safety light curtain is used. Or for two
sensor muting if the Safe 2/Safe 4 or GuardShield safety light curtains are used.
The Rockwell Automation muting control box is designed in accordance with the technical specification TS/IEC 62046.
The Rockwell Automation muting control box is factory configured for two sensor muting using a Safe 2, Safe 4, or GuardShield safety
light curtain. Other muting configurations or safety light curtains will require the reprogramming of the MSR42 muting control module
using the optical interface (445L-AF6150).
The factory default configuration of the MSR42 muting control module is as follows:
• Two sensor “T” type muting
• Without monitored muting lamp
• With manual start mode
• Without EDM
Mute dependant override is active and configured as follows:
T
(mdo)
is 60 seconds
Configured muting times
t
(sens)
is 4 seconds
t
(mute)
is 5 minutes
t
(msdel)
is 50 ms
The response time of the factory configured muting box is 17.30 ms.
Muting is indicated by the illumination of a white lamp on the front cover of the muting box or an external muting lamp may be
connected to an M8 pico quick-disconnect connector located on the bottom of the muting box.
The GuardShield Type 2 and Safe 2 light
curtains may be used with the muting
controller. However, the use of Type 2
devices with Category 4 devices does not
improve the safety level of the safety circuit
above a Category 2. Make sure that a risk
assessment determines that a Category 2/
Type 2 level of safety is sufficient for the
application.
