Carefully read this user’s manual to ensure correct operation before starting installation, wiring,
operation, maintenance, and inspection of the SafetyOne.
In this user’s manual, safety precautions are categorized in order of importance Warning and
Caution, as follows:
Warning
Warning notices are used to emphasize that improper operation may cause severe personal
injury or death.
Caution
Caution notices are used where inattention might cause personal injury or damage to
equipment.
Warning
Do not disassemble, repair, or modify SafetyOne. This will cause impairment of the safe
operability of SafetyOne.
Turn off the power to SafetyOne before starting installation, removing, wiring, maintenance, or
inspection. This can cause electrical shocks or fire hazard.
Before operating SafetyOne, carefully read the instruction sheet and this manual, and ensure that
the environment conforms to the requirements of SafetyOne specifications. If SafetyOne is
operated in an environment that exceeds the specifications, it causes impairment of the safe
operation of SafetyOne.
The installation, wiring, configuration, and operation of SafetyOne must be performed only by
“Safety responsible persons”. Safety responsible persons are personal who have requisite
qualification authorizing them as being capable of safely carrying out each step including the
designing, installation, operation, maintenance, and disposal of SafetyOne. Persons without
technical expertise of safety products must not use SafetyOne.

failure in SafetyOne or peripheral devices, Impairment of the safe operation of the system is
possible.
The start switch has to be placed outside the danger zone and in a safe position from which there
is good visibility for checking that no person is within the danger zone.
Do not use the start input and the external device monitor input as a safety input. When there is a
failure in SafetyOne or peripheral devices, Impairment of the safe operability of the system is
possible.
Use the SafetyOne in compliance with laws and regulations of the country in which it is being
used.
Use safety inputs and safety outputs in circuit configurations conforming to the application
according to the usage, and the safety requirements.

Warning
Calculate respective safety distances, taking into consideration the response time of the
SafetyOne, safety devices to be connected to the SafetyOne, and each other device that forms a
part of the system configuration.
Applicable safety performance is dependent on each system configuration.

circuit, as defined in UL508 or UL1310.
-Is in compliance with safety laws and regulations relating to electrical safety, EMC, and like under
the laws and regulations of the country in which it is being used.
Ground the V- line (0V DC) for ground diagnosis.
In the case of a new configuration or modified installation, be sure to perform a check for each
input and output function.
Implement protective measures that personal, other than safety responsible persons operating
the SafetyOne, are unable to modify the configuration.

Chapter 1
Chapter1 OVERVIEW
This chapter provides an understanding of the SafetyOne. Make efficient use of
the SafetyOne by thoroughly familiarizing yourself with its functions.
About the SafetyOne
The FS1A series of SafetyOneTM controllers provides safeguarding measures for various factory
automation equipment and systems, including robots, production machinery, semiconductor
manufacturing apparatus, food packaging machinery, and printing machinery. You can easily
configure the safety circuits by using multiple safety inputs and outputs and selecting the circuit
(logic) built into the SafetyOne.

OVERVIEW
1-2
Features of the SafetyOne
You can configure safety circuits without the use of complicated external wiring or
special software, thereby greatly reducing the number of developmental man-hours
required for product certification and the training time of safety responsible persons.
You can use the DIP switches to select from 24 different types of logic circuits and set
the OFF-delay timer value to best match your application.
The SafetyOne has 16 DIP switches and an ENTER button, which can be used to set the
built-in types of logic and the delay timer values for the safety output is OFF.
You can choice logic circuit from integrated 24 types.
You can set the timer value to 0, 0.1, 0.5, 1, 2, 5, 15, or 30 seconds. You can set the stop
category to 0 or 1.
Conforms to the international safety standards IEC 61508 SIL 3 and EN ISO 13849-1 PL e
(Control category 4).
The SafetyOne can be used for functional safety standard IEC 61508 series and IEC 62061 SIL
1 to 3, which define the safety performance of machinery that uses microprocessors and
software, and for performance levels a to e of EN ISO 13849-1 and Control category B to 4 of
EN ISO 13849-1, which define safety performance of machinery control systems.
You can directly connect an emergency stop switch, interlock switch, light curtain, and
other various safety devices.
The SafetyOne provides dualchannel direct opening inputs such as an emergency stop switch or
interlock switch; dual channel NO/NC inputs such as a non-contact interlock switch; and dual
channel safety inputs such as a safety light curtain or safetylaser scanner. These inputs can be
enabled byselecting a certain type of logic, therebyenabling various safetydevices.
The SafetyOne comes with monitor outputs and solenoid/lamp outputs, which can be
used as control signals.
With monitor outputs, you can monitor the status of the SafetyOne, including safety inputs and
outputs and error information. When connected to a PLC, the SafetyOne can be used to control
all apparatus and the entire system. The SafetyOne is also provided with solenoid/lamp outputs,
which can be used to directly control spring lock safety switches with solenoids. In logic4,
muting lamps can be connected to solenoid/lamp outputs.
Obtain detailed diagnostic information with the LED displays.
The SafetyOne has two 7-segment LED displays for displaying internal information and 30 LED
lights for displaying status. You can use these to display input and output information and to
obtain detailed diagnostic information on the status of the SafetyOne.
Control multiple safety devices (12 safety inputs and 4 safety outputs) by a single unit.
The SafetyOne has 12 safety inputs and 4 safety outputs, and it can be configured for up to 6
dual channel inputs and 2 dual channel outputs (in case of use as a single channel output, up to
4 outputs)

Note1. The drive port generates check pulses in order to diagnose input devices and internal
circuits. (Wiring and the diagnostic function are different depending on the logic
selected. See “Chapter 5 LOGIC” for details. But the basic function is same.)
Note2. For cables longer than 30m between SafetyOne and connected devices, or wiring drive
terminals and receive terminals separately, use grounded shielded cables to assure
electromagnetic compatibility.
Note3. In the common connection of several interlock switches, applicable safety performance
depends on result of risk assessment for whole of the safety configuration. Refer to
ISO14119 for analysis the connection.
