Omron F3S-B Series Datasheet page 17

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 Eu-
ropean standard EN954-1.
Do not use the F3S-B in category 3 or 4 systems.
2. A qualified person, as determind 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 sit-
uation.
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 be-
low so that the F3S-B can comply with the applicable stan-
dards 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.

WARNING
!
(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 characterisitics re-
quired for the power source for Class 2 Circuit or Lim-
ited Voltage / Current Circuit as defined in UL508.
(8.) The power supply must conform to regulatory require-
ments and standards, regarding EMC and electrical
equipment safety, of the country where the F3S-B is in-
stalled and where machinery will be operated, for ex-
ample: The EMC Directive (industrial environment)
and the Low Voltage Directive in EU.
9. Do not use the F3S-B in a direct retroreflective configura-
tion. Otherwise detection may fail.
