E3FS Datasheet, PDF (10/10 Pages) Omron Electronics LLC – Safety design for category 2. Suitable for detecting human bodies in hazardous area.

Precautions
WARNING
Indicates a potentially hazardous situation which, if not avo-
ided, could result in death or serious injury. Indicates prohibi-
ted actions.
WARNING
When the E3FS is used without a safety control unit, do not
use the E3FS as a safety device nor a part of safety systems
for ensuring safety of persons.
When the E3FS is used without a safety control unit like the
F3SP-U1P-TGR, it is in accordance with the requirements of
the safety related control system to category B as defined in
the European standard EN954-1.
The E3FS is in accordance with the requirements of the safety
related control system to category 2 only when it is connected
with a specified control unit.
E3FS-10B (PNP):
Type F3SP-U1P-TGR safety control unit must be used.
The F3SP-U1P-TGR executes a periodic test every 27 ms.
WARNING
Make sure that personnel operating the E3FS are
knowledgeable about the machine on which it is installed.
Read this manual and the control unit manual completely.
Be sure the information provided is understood before
attempting to operate the E3FS.
Multiple E3FSs must be sufficiently far from each other to
avoid mutual interference.
Regarding the calculation of the safety distance, obey the
control unit manual and related standards, e.g. EN999 when
the E3FS is used as a safety device.
Regarding the avoidance of malfunction caused by shiny
surface, obey the control unit manual when the E3FS is used
as a safety device.
Use an opaque test piece with 11 mm in diameter and 200
mm or greater in effective length to check the detection
capability.
Do not connect the E3FS to an AC or DC power supply with
higher voltage than nominal 24 VDC. 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 E3FS is installed. For
example, the power supply must fulfil EN60742 requirements
for double insulation and must conform to EMC Directive and
Low Voltage Directive in EU.
NOTICE
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 E3FS cable separated from high-
potential power line or through an exclusive conduit.
E3FS must not be used in water.
The E3FS is ready to operate 100ms after the E3FS is turned
ON. If the load and E3FS are connected to independent
power supplies respectively, be sure to turn ON the sensor
before turning the load ON.
To extend the cable, use a wire of 0.3mm² or more. However
do not extend it more than 50m.
Do not use the E3FS in explosive or flammable gas.
Do not disassemble, repair, and modify the E3FS.
Do not exceed a torque of 2.0N·m (20Kgf·cm) when tightening
mounting nuts for plastic models
20.0N·m (200Kgf·cm) when tightening mounting nuts for
metal models.
For connector type of E3FS, make sure the cable connector
is rated IP54 or higher.
Be sure to connect or disconnect the connector after turning
OFF the E3FS.
Hold the connector cover to connect or disconnect the
connector.
Secure the connector cover by hand. Do not use any pliers.
The proper tightening torque range should be checked
according to connector specification. Be sure to tighten the
connector securely.
