WARNING: Indicates a potentially hazardous situation which, if not avoided, will result in minor or moderate injury, or may result in serious injury or death. Additionally there may be significant physical damage.

CAUTION: Indicates a potentially hazardous situation which, if not avoided, will occasionally result in minor or moderate injury, or result in physical damage to property.

A symbol with an exclamation mark (!) inside a circle indicates mandatory actions.

A symbol with a prohibition sign (circle with a diagonal line) indicates prohibited actions.

DO not disassemble, modify, or attempt to repair the F3SX controller. Doing so may damage the original safety functions.

DO not operate the F3SX controller in a hazardous environment, such as an environment that contains flammable or explosive gas. Doing so may cause fire or explosion.

Do not connect the F3SX power input with a DC power supply or AC power supply exceeding the rated voltage. Also do not make reverse connection for the polarity of power supply. Doing either of these may cause breakdown of device and/or danger such as an electric shock.

DO not use the F3SX’s communication functions for the purpose of configuring a safety system. Doing so may cause serious danger if any trouble occurs with the wiring or programming of the programmable controller.

Do not use the auxiliary input terminals (start command input) for connection with a safety input device for the purpose of configuring a safety system. Doing so may cause serious injury to humans when a trouble occurs with F3SX or the peripheral devices.

Apply neither of a voltage exceeding the rated nor an AC power supply across the auxiliary input terminals (start command input). Doing either of these may cause breakdown of device and/or danger such as an electric shock.

The auxiliary solid-state output (at the AS1, AS2 and AS3 terminals) is not a safety output. Do not use it for the purpose of configuring a safety system. Doing so may cause serious injury to humans when a trouble occurs with F3SX or the peripheral devices. (N module built in types)

The external indicator output is not a safety output. Do not use it for the purpose other than indication. (N module built in types)

For DC solid state safety output: Do not short-circuit the output lines to the 24V DC line. Doing so will make the output always ON and dangerous. Also, ground the OV line of the power source so that the output does not become ON when the output line is grounded. (E module built in types)

The single-beam safety sensor input module (B1 module) of F3SX is for the exclusive use with the OMRON Model E3FS-10B4 (Type 2) and E3ZS-T81A(Type 2). Be sure to avoid connecting the module to the single-beam safety sensor other than the specified for the exclusive use. (B1 module built in types)

If the mode selection input line of the single-beam safety sensor receiver is connected to OV, the output turns ON when light is interrupted (Dark ON), which no longer configures the safety system. Ensure connection of the mode selection input line to 24V DC to make the sensor output ON when light is incident (Light ON). (B1 module built in types)

Never use with a load in excess of the trip capacity (contact voltage, contact current). Doing so may damage the output circuit and cutoff may not be possible.

When transferring a F3SX product to another user, be sure to attach this User’s Manual.

When this product is used in a safety system, a “Responsible Person” must strictly conform to the standards, legislations and regulations of the country and the local government under which the system is operated.

A “Responsible Person” who is well aware of and familiar with the machine must implement the installation of the F3SX and confirmation thereafter. Users must have thorough understanding about the relevant installation requirements, safe distances, control devices and the functions before starting operation.

For the inspection and/or maintenance of the F3SX, a “Responsible Person” must confirm that the work has been properly performed.

In order to prevent hazardous situation, a “Responsible Person” must implement the inspections according to the User’s Manual at least once for every six months. Failure to do so may lead to an accident including a serious injury to humans.

Whenever the F3SX does not operate properly, the user shall stop the machine immediately and report it to the “Responsible Person”.

In order for F3SX to satisfy EN60204-1, IEC61496-1 and UL508, the DC power unit must comply with all of the following requirements:

Voltage within the rated (24V DC ± 10%).

Do not share the power source with other devices or machines. When the power source is shared by multiple devices, consider margins for the total rated current.

Compliant with the EMC Directive, for Industrial environments.

Double or reinforced insulation between the primary and secondary circuits.

Automatic recovery of over-current protection characteristics (voltage drop).

20ms or over of the output hold time.

Satisfies the output characteristics requirements of a class 2 circuit or equivalent limited energy circuit, as stipulated in UL508.

Compliant with the laws and standards in relation to EMC and other electric device safety in the country or area where this unit is used (Example: EMC Directive and Low Voltage Directive in EU).

When using a commercialized switching regulator, be sure to ground FG (frame ground terminal). (If not grounded, it may cause erroneous operations due to the switching noises.)

Use appropriate control devices to materialize the safety functions. Failure to do so may cause deterioration in the safety performances.

Wiring must be done while the power is turned OFF either for F3SX or the devices connected with it. Doing it with the power ON may cause an electric shock. And external devices in connection with this product may behave in an unexpected way.

Ensure that the connections are made properly at the input and output terminals. Failure to ensure this may cause an electric shock or damage the safety functions.

Ensure that sufficient attention is given so that shared causes of faults do not cause the redundant safety circuit to become ineffective.

Set up a protective structure around the applicable machines so that nobody can reach the hazardous area of the machines without passing through the detection zone. If any works should be carried out in such hazardous area, set the sensors that always detect whole or a part of human bodies. Failure to do so causes the detection errors of human body and will lead to a serious injury.

Measure the maximum stop time with the actual machine configurations and periodically confirm that the stop time remains unchanged.

Never fail to secure the safety distances to the hazardous areas around the machine.

The reset switch must be installed in a place where the entire dangerous zone can be viewed, and in a way that the switch cannot be operated from the dangerous zone.

In order to maintain the safety functions, put the product in the state of output-OFF (the emergency-stop state) once every 24 hours.

Do not use F3SX for the machines that cannot be stopped immediately by the electric control at an emergency. Such machines cannot stop before the human body reaches the hazardous area and will cause a serious injury.

With regard to the relay output, install a fuse in serial with the output contacts. (Relay output module built in types)

Be sure to align the devices so as to prevent mutual interference when using multiple safety light curtains, multi-beam safety sensors or single-beam safety sensors. Failure to do so may cause non-detectable conditions and a serious injury to humans.

Regarding setting to F3SX by using the function set-up software for model F3SX (Model F3SXCD, sold separately), keep the set contents in the history. (Configurable types)

After changing any settings to F3SX by using the function set-up software for model F3SX (Model F3SXCD, sold separately), be sure to carry out the “Function test” and keep the test results in the history. (Configurable types)

DC solid-state safety output: Be sure to configure the safety system by using two channels. Only with one channel to be used, the safety functions of the system will be degraded. It may cause serious injury to humans when a trouble occurs. (E module built in types)

DC solid-state safety output: Connect a load across the output terminal and the OV line (PNP output). If it is connected between the output terminal and the 24V DC line by mistake, the output may turn ON when an emergency-stop occurs and cause a dangerous situation. (E module built in types)

The safety category is determined by the entire safety control system. Design and use it in accordance with all the related standards. Consultation with an independent certification organization is recommended.

The life duration of the relays varies depending on the switching conditions or loads, etc. Use the relays within an appropriate switching times, after confirming the limit of switching times with the actual devices under the actual conditions.

If the DIN rail is too short for the width of F3SX, the product may drop out of the rail by vibration. Use end plate (Model PFP-M, sold separately), to fix F3SX on the DIN rail where necessary.

Use F3SX in an enclosure rated at least IP54 (IEC60529).

For ventilation, allow for 5mm or more on both sides of the F3SX and 50mm or more above and beneath.

Stranded wire should be processed with insulation-covered bar terminal (DIN46228-4 standard compatible type) at its ends before using for connection. Conforming wire (when using recommended bar terminals): 0.34 to 1.5mm² AWG22 to 16.

Be careful not to catch a finger in the connector when installing it.

Connect firmly at the time of main body mounting and connect the cable connectors.

Allow some leeway for the wires and do not tighten the wires when wiring connection cables to F3SX, and confirm that any cable may not block the movements of workers or objects.

For the external indicator, use a filament-type lamp for the externally connected indicator. With an LED type indicator, the perfect detection of a trouble is not available. (N module built in types)

Yes, attach the attachment (Part No. F3SX-N-ATT 14pin) – 1 pc. between the EL1 and EL2 terminals when connecting no external indicator.
