Term
Description
A
Allowable delay time
The allowable amount of time from when a state of the safety output changes until a state of the external
device monitoring input changes. The F3SJ-B enters lockout if this time is exceeded.
Auxiliary output
Basic type (basic system) gives inverted signal of safety output, and Basic type (muting system) gives
ON output at muting/override.
B
Basic system
Basic system indicates the F3SJ-B with its default factory settings. The basic system provides basic
safety light curtain functions. Most functions can be used without performing additional configuration.
D
Detection capability
Minimum size of an object that can be detected in the protective height of the F3SJ-B.
E
Effective aperture angle
(EAA)
Range of angles for which the F3SJ-B can operate.
External device
monitoring
Function that detects malfunctions, such as welding, in external relays (or contactors) that control the
hazardous zone of a machine, by monitoring the operation of N.C. contacts.
External test
Function that stops emission at any time to check that the safety output is being properly turned OFF.
I
Interlock
Function that holds the safety outputs to OFF until safety is ensured and a reset input is applied.
L
Lockout
Function that holds safety output OFF when an error is detected by the F3SJ-B.
Lower beams
Indicate beams on F3SJ-B's power supply end.
M
Muting
Function that temporarily disables the safety function of the F3SJ-B, keeping the safety output ON even
if beams are being blocked.
O
Output operation mode
A state of signal sent from the safety output or auxiliary output.
Override
Function that turns the safety output ON when the muting function is not working.
P
PELV
Stands for Protected Extra Low Voltage.
A grounded circuit separated by double insulation or equivalent from hazardous voltage, and does not
generate voltage that exceeds ELV under normal conditions and under single-fault conditions. Normally,
protection for direct contact is required.
Primary sensor
Name of the F3SJ-B connected nearest the power supply when series-connected.
R
Reset
Releases the interlock state/lockout state.
Response time from ON
to OFF
Time period from when the F3SJ-B is blocked until the safety output turns from ON to OFF.
S
Safety output (OSSD)
The sensor o24 V when it is unblocked. Safety output can be used for safety applications.
Secondary sensor
Name used for F3SJ-B other than the primary sensor, when series-connected.
SELV
Stands for Safety Extra Low Voltage.
An ungrounded circuit separated by double insulation or equivalent from hazardous voltage, and does
not generate voltage that exceeds ELV under normal conditions and under single-fault conditions. If the
nominal voltage exceeds 25 VAC or 60 VDC, protection for direct contact is required.
V
Vs
Voltage value in your usage environment.
