Functional Description
The device 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 relay unit. There
are three N.O. safety outputs plus one N.C. auxiliary for control indication.
If input switch is closed and supply is on A1-A2, the MSR5T safety relay is ready for
operation and the PWR status indicator is on. The MSR5T safety relay can now
activate via the reset (feed back 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 must be
wired in series into the feedback circuit X1-X2 and is used to monitor contactor
function. This arrangement maintains that the MSR5T safety relay start is only
possible if the contactors are at rest and their N.C. contacts are closed. If X1-X2 is
closed at the time when voltage supplies at A1-A2, the unit performs an automatic

reset.
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.
All information complies with the state of this
publication and is subject to change without notice.
ATTENTION: Do not dismantle the unit.
