P
Pass-Through Hazard
A pass-through hazard is associated with applications where
personnel may pass through a safeguard (which issues a stop
command to remove the hazard), and then continues into the
guarded area, such as in perimeter guarding. Subsequently, their
presence is no longer detected, and the related danger becomes
the unexpected start or restart of the machine while personnel are
within the guarded area.
PELV
Protected extra-low voltage power supply, for circuits with earth
ground. Per IEC 61140: "A PELV system is an electrical system in
which the voltage cannot exceed ELV (25 V ac rms or 60 V ripple
free dc) under normal conditions, and under single-fault
conditions, except earth faults in other circuits."
Q
Qualified Person
A person who, by possession of a recognized degree or certificate
of professional training, or who, by extensive knowledge, training
and experience, has successfully demonstrated the ability to solve
problems relating to the subject matter and work.
R
Run Signal
The input signal monitored by the Controller that, when detected,
causes one or more safety outputs to turn On, if their other
associated input signals are also in the Run state.
S
SELV
Separated or safety extra-low voltage power supply, for circuits
without earth ground. Per IEC 61140: "A SELV system is an
electrical system in which the voltage cannot exceed ELV (25 V ac
rms or 60 V ripple free dc) under normal conditions, and under
single-fault conditions, including earth faults in other circuits."
Simultaneous
The setting that permits a signal disparity between channels
within the input device for a limited time, without going into a
fault condition. If a signal disparity exists for more than 3
seconds, then a fault condition occurs.
Single-Channel
Having only one signal line for a safety input or safety output.
Start Up Test
For certain safety devices, like safety light screens or safety
gates, it can be an advantage to test the device on power up at
least one time for proper function.
Stop Signal
The input signal monitored by the Controller that, when detected,
causes one or more safety outputs to turn Off. In this manual,
either the input device or device signal is said to be in the Stop
state.
System Reset
A configurable reset of one or more safety outputs to turn On
after Controller power-up, when set for manual power-up, or
lockout (fault detection) situations.
