2 Important Safety Information
• Power supply
Before turning on the power for the product, be sure to confirm that the power source meets the
specified voltage requirements. Avoid using unstable power sources; doing so may lead to
malfunctions.
• Operating in the presence of gases
Do not operate this product in locations where combustible or explosive gases or vapor is
present. Operating this product in such environments is extremely hazardous.
• Action if a gas alarm occurs
A gas alarm indicates an extreme hazard. The user must take appropriate action based on the
situation.

6/60
• Do not use devices that generate strong magnetic fields near the product.
Use near strong magnetic fields may cause unstable operation.
• Do not disassemble or modify the product or alter the settings unnecessarily.
Altering the settings unnecessarily without a proper understanding of the details may prevent the
alarm from operating correctly. Use the product correctly in accordance with this operating
manual.
Never attempt to disassemble or modify the product. Doing so will void product performance
guarantees.
• Removing the FLX3402 (I/O extension card)
Do not remove the FLX3402 (I/O extension card) while the Ewon Flexy 205 is turned on.
Likewise, do not turn the power on while the card is removed. This may cause problems with the
system program and prevent correct operation. Be sure to turn the power off before removing the
card.
• Monitoring from the browser alone is not recommended.
Email abnormality alerts may not be sent and monitoring may be interrupted if cables are
damaged or communication problems arise when an alarm occurs. To ensure safety, we
recommend using the contact outputs and incorporating alarms such as rotating lights and
buzzers into the system.
• Contact outputs
Use the contact outputs for external alarm lamps and buzzers. Riken Keiki rejects liability for all
malfunctions in cases in which the contact outputs are used for other controls.

4 Usage Instructions
4-1 Usage note
The usage precautions apply to both users who have previously used the product and first-
time users. Failure to comply with these precautions may result in product failure or improper
functioning.
Use the product as soon as possible after delivery.

9/60
4-2 Precautions regarding installation location
The product is a precision device. The specified performance may not be achieved depending on
the location (environment) in which the product is installed. Check the installation location
environment. The end user must implement appropriate remedial measures where necessary.
•Do not install the product in locations subject to vibration or impact.
The product contains precision electronic components. Install the product in a stable location
not exposed to vibration, impact, or risk of falling.
•Do not install in locations exposed to water, oil, or chemicals.
Avoid installing the product in locations exposed to splashing liquids such as water, oil, and
chemicals.
•Do not install in locations where temperatures can fall below -25 °C or exceed 60 °C.
The operating temperature range for the product is between -25 °C and 60 °C. Install in a
stable location within the specified operating temperature range and free of sudden
temperature fluctuations.
•Do not install in locations exposed to direct sunlight or sudden temperature
fluctuations.
Avoid locations exposed to direct sunlight or radiant heat (infrared radiation from high-
temperature bodies) and locations that may subject the product to sudden temperature
fluctuations.
Condensation may form inside the product, or the product may be unable to adjust to sudden
temperature fluctuations.

10/60
4-3 System design precautions
Unstable power sources or noise may result in malfunctions or false alarms.
•Use a stable power source.
Note that the product’s external output and alarm contacts may activate while the system
stabilizes at power-on or in the event of an instantaneous power failure. In such cases, either
use a UPS (uninterruptible power system) or take appropriate measures on the side
receiving the power.
Supply this product with a power source that meets the following requirements:
Power supply 12 - 24 V DC ± 20 %
Power consumption 72 W Max.
•Use the alarm contacts correctly.
The alarm contacts on this product are designed to transmit signals that activate external
buzzers and alarm indicators. Do not use for control purposes—for example, do not use to
control shutoff valves.
A de-energized b contact (break contact) may cause a momentary open operation due to an
external force or other physical impact.
If a b contact is used as an alarm contact, implement measures to account for such momentary
operations—for example, adding a delay operation (of approximately one second) to the signal
on the b contact receiving side.
4-4 Installation procedure
The product is designed to be mounted on a DIN rail or wall.
For more information, refer to the Ewon Flexy 205 Specifications.

6 Individual Operations
6-1 Gas alarm pattern
Gas alarm: Triggered if the concentration of the detected gas reaches or exceeds the alarm
setpoint
《Auto reset or self-latching operation》
NOTE
•The gas alarm operation will depend on the operation of the gas detector(s) connected to
the product.
•The gas detector alarm setpoints (first and second alarms) and alarm pattern (auto reset or
self-latching) are factory-set before shipment.
•An alarm delay (standard setting: two seconds) is set for gas detectors to prevent
accidental alarm activation.
<Indications>
•Gas concentration display
Displays the current gas concentration.
•Alarm status display (ALM1: Yellow), (ALM2: Red)
The alarms are two-step alarms.
The alarm lamps light up when the corresponding alarm setpoint is reached or exceeded.
The alarm status display differs for Chart (list screen) and Details (details screen).
Chart (list screen)
When a first alarm occurs, the title information ALM1 and the corresponding gas detector
information light up in yellow.
When a second alarm occurs, the title information ALM2 and the corresponding gas detector
information light up in red.
Details (details screen)
When a first alarm occurs, the title information ALM1 and [Gas alarm (ALM1)] light up in
yellow.
When a second alarm occurs, the title information ALM2 and [Gas alarm (ALM1)] light up in
yellow, and [Gas alarm (ALM2)] lights up in red.

16/60
<When gas detector alarm pattern is auto reset>
When the gas detector is set to auto reset, the contact is triggered if the gas concentration
reaches or exceeds the alarm setpoint. The contact operation is automatically reset when the
gas concentration falls below the alarm setpoint.
When the buzzer contact is activated, it can be deactivated by buzzer stop.

6-2 Fault alarm pattern
A fault alarm is displayed and the fault alarm contacts are triggered if a fault occurs with a
gas detector.
Determine the cause and take appropriate action.
After the gas detector has successfully recovered from the fault, it restarts with the process
normally performed right after it is turned on (initialization).
Depending on the type of fault alarm, the indications given will be as follows:
•If the problem lies with the gas detector and the fault occurs repeatedly, contact your agent
or Riken Keiki immediately.
<Indications>
•Detector fault
When a detector fault occurs, the title information FAULT and [Detector fault] for the
corresponding gas detector light up in orange.
•Sensor fault
When a sensor fault occurs, the title information FAULT and [Sensor fault] for the
corresponding gas detector light up in orange.
•Flow rate abnormality
When a flow rate abnormality occurs, the title information FAULT and [Flow fault] for the
corresponding gas detector light up in orange.
