INFLUENCE OF MUTUAL INTERFERENCE
When installing two or more E3ZSs to each other, considerations must
be made to prevent mutual interference.
・
Install so that any E3ZSs emit in the opposite directions (See below).
・
Install a light interrupting wall in between sensors.
・
Install the E3ZSs facing away from the one another to
eliminate mutual interference.
Note : When using multiple sets of E3ZSs, be sure to
confirm that mutual interference is not occurred.

SUITABILITY FOR USE
1. Read this instruction sheet thoroughly to understand before using the
product.
2. When used in combination with the F3SX safety controller, make
sure that the B1 module is properly connected.
3. A load must not be shorted. A load must not be used with current
higher than the rating. Do not apply the reversed supplied voltage.
Be sure to route the E3ZS cable separated from high-potential power
line or through an exclusive conduit.
4. Do not remove the label (yellow) from the sensor. Doing so may
violate the specifications.
5. Wire the cable so that it has some slack and does not prevent
personnel or object passage.
Allow some leeway for the wires and do not tight the wires when
connection cable to F3SX, and confirm that any cable may not block
the movements of workers or objects.
6. Do not disassemble, repair or modify the E3ZS.
7. Be sure to dispose of the E3ZS as industrial waste.
Precautions for Safe Use
●
Alert Statements
WARNING
When the single beam safety sensor model E3ZS is used as a
safety device or a part of safety systems for ensuring safety of
personnel, be sure to use it with the safety controller model F3SX
series.
WARNING
If the mode selection input line of the receiver is connected to 0V,
the output turns ON when light is interrupted (Dark ON), which no
longer configures the safety system. Be sure to connect the mode
selection input line to 24V DC to make the sensor output ON when
light is incident (Light ON).
Always maintain a safe distance between the E3ZS and a
hazardous part of a machine. Be sure to refer to the related
standards (EN999) for the calculation of safety distance.
Use an opaque test rod with 18mm in diameter and 200mm or
greater in effective length to check the detection capability. The
E3ZS cannot detect transparent materials.
Do not use the E3ZS in a reflective configuration, otherwise
detection may fail.
Do not install the E3ZS in a location where it can be affected by
wall reflections to avoid detection failure, which may result in
serious injury.
When using multiple sets of E3ZS, arrange them to prevent mutual
interference. Failure to do so may cause the sensor not to detect,
resulting in serious injury.
The E3ZS does not offer protection to the operator’s body from
projectiles existing the hazardous area. Proper means of
mechanical guarding must be provided to ensure protection from
these potentially hazardous projectiles.
Wiring must be done while the power is turned OFF. Doing it with
the power ON may cause an electric shock.
Do not connect the E3ZS to an AC or DC power supply with higher
voltage than nominal DC24V. Otherwise the sensor may explode,
burn, or cause electric shock. The power supply must conform to
regulatory requirements and standards, regarding EMC and
electrical equipment safety, of the country where the E3ZS is
installed. For example, the power supply must fulfill EN60742
requirements for double insulation and must conform to EMC
Directive and Low Voltage Directive in EU.

Areas exposed to intense interference light, such as direct sunlight;
・
Areas with high-humidity where condensation is likely to occur;
・
Areas exposed to corrosive, flammable or explosive gases;
・
Areas in the presence of substances, such as heavy smoke or
particulate matter, that may deteriorate product quality;
・
Areas exposed to vibration or shock levels higher than specification
provisions;
・
Areas where the product may come in direct contact with water, oil,
and chemicals;
2. Do not install the E3ZS in water.
3. To extend the cable, use a wire of cross-sectional area 0.3mm
2
or
more. However do not extend it more than 100m.
4. Be careful not to exceed a tightening torque of 0.5 Nm. Also, if it is
not tight enough, vibration may cause it to come loose.
5. When cleaning, avoid using thinner, benzene or acetone.
6. Power supply specifications
For combined DC power supply, use the following UL certified
products:
(1) Limited voltage current circuit that conforms to UL508
Circuit with a power supply that consists of a secondary coil of
an insulated transformer that satisfies the following conditions:
-Maximum voltage (with no load) : 30Vrms (42.4V peak) or less, and
-Maximum current
: 8A or less (including short-circuit), or
When limited by a circuit
protector (fuse, etc.) with the
ratings shown in the table below
(2) Class 2 power supply unit that conforms to UL1310
(3) Circuit (class 2 circuit) with 30Vrms (42.4V peak) or less of
maximum voltage, and which uses a class 2 transformer that
conforms to UL1585 as its power supply
