Minotaur MSR117T Safety Relay
Catalog Numbers 440R, 440R-B23211
Summary of Changes
This publication contains the following new or updated information. This list
includes substantive updates only and is not intended to reflect all changes.
Introduction
This device is intended to be part of the safety-related control system of a
machine.
Rockwell Automation does not accept responsibility for failure of this device if you
do not implement the procedures that are given in this publication, or if you use
the unit outside the recommended specifications that are listed in this publication.
Description
The unit can connect to safety gate switches or E-stop buttons and requires a
supply voltage that is applied via the safety device to operate this safety relay.
There are three N.O. safety outputs, plus one N.C. auxiliary for control indication.
If the input switch is closed and the supply is on A1-A2, the MSR117T safety relay is
ready for operation and the PWR status indicator is on. The MSR117T safety relay
can now be activated via the reset (feedback loop) circuit X1-X2. The safety
contacts 13-14 and 23-24 and 33-34 close and enable operation, signalized by the
second status indicator.
One N.C. contact respectively of the connected contactors or expanders has to be
wired in series into the feedback circuit X1-X2 and is used for monitoring contactor
function so that MSR117T safety relay start is feasible only if the contactors are at
rest and their N.C. contacts are closed. If X1-X2 is closed at the time when voltage
is supplied at A1-A2, the unit performs an automatic reset.

IMPORTANT
Before installation, perform a risk assessment to determine
whether the specifications of this device are suitable for all
foreseeable operational and environmental characteristics
of the machine to which it is to be fitted. At regular
intervals during the life of the machine, check whether the
characteristics foreseen remain valid.
WARNING:
Danger of serious injuries. Misuse can result in
malfunction.
• Only authorized and trained personnel can start up, assemble,
or retrofit the device.
• Installation must be in accordance with the following steps.
WARNING:
Danger of serious injuries.
Incorrect installation or manipulation can result in serious
injuries. Do not defeat, tamper, remove, or bypass this unit.
ATTENTION:
If any malfunction or damage is present, do not
attempt to repair. Replaced the unit before machine operation
is allowed. Do not dismantle the unit.
IMPORTANT
The safety inputs of these products are described as
normally closed (N.C.), that is, with the guard closed, the
actuator in place (where relevant), and the machine able to
start. You must prevent exposure to shock and/or vibration
in excess of those specifications in IEC 60068 part: 2-6/7.
Adherence to the recommended inspection and
maintenance instructions forms part of the warranty.
IMPORTANT
All information complies with the state of this publication
and is subject to change without notice.
