Monitored manual reset
A monitored reset means that the safety
relay will not be reset if the reset button
gets jammed when pressed in or if the
input short-circuits. In order for the reset-
ting to be complete, the input must be
closed and opened before the outputs
can close.
Automatic/unmonitored manual
reset
Automatic reset means that the outputs
are closed immediately when both the
input conditions are satisfied and the
test input is closed.
Testing of contactors, relays &
valves
Can be carried out with both auto-
matic and manual reset.
Contact strips/Safety mats
Category 3, up to PL d
For an unpressurised mat/strip, both
he relay inputs must be closed for the
outputs to be activated. In the case of an
activatedmat/stripandshort-circuitinput
channels, the relay will be de-energized.
Current limitation prevents the safety
elay from being overloaded when the
channels short-circuit.
