F3S-B
19
WARNING
1. The F3S-B is a TYPE 2 electro-sensitive protective equip-
ment, intended to be used as or with the safety related part
of control system to category 2,1, or B as defined in the
European standard EN954-1.
Do not use the F3S-B in category 3 or 4 systems.
2. A qualified person, as determined by local regulations,
must confirm that installation, inspection and maintenance
are implemented correctly.
3. Do not short the output lines to the +24 V line. Doing so will
cause the output to be always ON, creating a hazardous
situation.
4. Do not connect the F3S-B to a power supply with voltage
higher than 24 VDC + 20%. Do not connect the F3S-B to
an AC power supply.
5. Be sure to conduct inspections regularly.
6. The F3S-B cannot be used in applications where hazard-
ous projectiles may exit the protected zone.
7. Do not disassemble, repair, or modify the F3S-B.
8. DC power supply units must satisfy all of the conditions
below so that the F3S-B can comply with the applicable
standards IEC 61496-1 and UL 508.
(1.) The power supply voltage must be within rating
(24 VDC ± 20 %).
(2.) The power supply is connected only to the F3S-B and
to the electro-sensitive protective function of the
F3S-B, such as a safety controller and muting
sensors, and it has enough rated current for all the
devices.
(3.) The power supply uses double or reinforced insulation
between the primary and secondary circuits.
(4.) The power supply automatically resets overcurrent
protection characteristics (voltage drop).
!
(5.) The power supply maintains an output holding time
of at least 20 ms.
(6.) FG (frame ground terminal) must be connected to
PE (protective earth) when using a commercially
available switching regulator.
(7.) The power supply must have output characteristics
required for the power source for Class 2 Circuit or
Limited Voltage/Current Circuit as defined in UL508.
(8.) The power supply must conform to regulatory
requirements and standards, regarding EMC and
electrical equipment safety, of the country where the
F3S-B is installed and where machinery will be
operated. For example: The EMC Directive
(industrial environment) and the Low Voltage
Directive in EU.
9. Do not use the F3S-B in a retroreflective configuration, or
detection may fail.
