INSTALLATION CONDITIONS
For your safety, always heed the following:
DC Power Supply Units Must Satisfy
All These Conditions
•
The power supply is connected to the F3S-A
j
P only and not
to other devices or equipment.
•
The power supply voltage is within the rating (24 VDC
±
10%).
•
Wiring is conducted only after confirming polarities of the
power supply.
•
The power supply conforms to EMC Directive (industrial
environment).
•
The power supply conforms to Low-voltage Directive.
•
The power supply uses double or reinforced insulation be-
tween the primary and secondary circuits.
•
The power supply automatically resets overcurrent protection
characteristics (voltage drop).
•
The power supply maintains an output holding time of at least
20 ms.
•
When using a commercially available switching regulator,
make sure FG (frame ground terminal) is connected to PE
(protective earth). Faulty operation caused by switching
noise may result if the terminal is not connected.
•
Use one of the following wiring configurations to reduce noise
terminal voltage to the primary side of the power supply:
•
Connect the 0V line to PE (protective earth).
•
Mount a capacitor with a minimum 47-nF capacity and
minimum 630 V voltage rating between the 0V line
and PE.
•
Recommended Power Supplies: S82K, S8PS, S82J or S82H
made by OMRON.
Load Must Satisfy All These Conditions
•
Is not shorted.
•
Does not use current higher than the rating.
•
Is double insulated to protect the load from hazardous
voltage levels when the load is a relay.
Correct Use
Failure to observe the following items may result in F3S-A
j
P
damage, deterioration, or improper operation.
Installation Environment
Do not install the F3S-A
j
P in the following environments:
•
Areas exposed to intense interference light such as direct
sunlight.
•
Areas with high-humidity where condensation is likely to
occur.
•
Areas exposed to corrosive gases.
•
Areas exposed vibration or shock levels higher than
specification provisions.
•
Areas exposed to contact with water.
Do not use cellular phones or transceivers near the F3S-A
j
P.
Wiring and Mounting
•
Be sure to turn OFF the power prior to wiring, or the
diagnostic function may prevent the F3S-A
j
P from operating.
•
Be sure to use shielded twisted-pair cables (cross-section at
least 0.2 mm
2
in diameter) when extending the sync line
without using an F39-JA
j
A Series Connection Cable.
Connect the shield to 0 V line.
•
When using resin or other connectors in place of the unit’s
metal connector, make sure the conductor path in the
connector is rated IP54 or higher.
•
Check signal names for all terminals and wire terminals
correctly.
•
When using two or more F3S-A
j
P sets, be sure to connect
a sync line and turn ON all power supplies at the same time
(within 0.5 s). Never exceed specifications for the total
number of sets and total number of the optical beams (up to
192 beams).
•
The F3S-A
j
P will start operating in five seconds after the
power is turned ON. Make sure that no faulty operation will
occur in the control system.
•
Once power is turned ON, do not turn it OFF again before the
F3S-A
j
P becomes operational (LED indicator lights).
•
Be sure to route F3S-A
j
P wires separated from high-poten-
tial power lines or to route through an exclusive conduit.
•
Make sure the emitter and receiver are facing the proper
direction.
•
Use the interference light search function for no longer than
8 hours from startup, or the F3S-A
j
P will switch to OFF-hold
condition (stop due to temporary failure).
•
Use the emitter and receiver packed with the F3S-A
j
P and
install them opposite to each other.
