Preface
•
Recovery Time -
The time that is required for the input to be in the LO
state before returning to the HI state.
•
Reset -
Safety relays offer two types of reset: monitored manual and
automatic/manual.
–
Monitored Manual -
The safety relay performs a reset function when
the reset signal goes from OFF to ON and then back to OFF in a
prescribed time-period. The reset occurs on the trailing edge.
–
Automatic/Manual -
The safety relay performs a reset function if
the reset input is ON. If the reset input is connected directly to 24V,
the reset function is executed immediately when the inputs become
closed or active. If a contact (push button or equivalent device) is
used in the reset input, the reset function is executed on the leading
edge of the reset signal (if the inputs are closed or active).
•
Response Time -
Describes the time between the trigger of one input to
the OFF state of the output. Throughout this manual, the safety outputs
are described as turning off immediately, which means that the safety
outputs turn off within the response time.
•
OSSD (Output Signal Switching Device) -
Typically a pair of
solid-state signals that are pulled up to the DC source supply. The
signals are tested for short circuits to the DC power supply, short
circuits to the DC common and shorts circuits between the two signals.
•
Single Wire Safety (SWS) -
A unique, safety-rated signal that is sent
over one wire to indicate a safety status. The SWS can be used in safety
systems that require Category 4, Performance Level e, per ISO 13849-1
and safety integrity level (SIL) 3, per IEC 62061 and IEC 61508. When
an SWS signal is present, this publication describes this state as
ACTIVE or ON. This signal is also referred to as the logic link signal.
