Operating Precautions
This detector is a gas detector that detects toxic gases in the air and triggers a gas alarm.
The gas detector is a safety unit, not an analyzer or densitometer which performs quantitative/qualitative
analysis/measurement for gases.
Please fully understand the following points before using it, so that it can be used properly.
1. The detector may be interfered by gases other than the gas to be detected, solvents, vapors etc.
Please note that the alarm may be triggered by interference. In addition, it may be fluctuated by
environmental (temperature, humidity etc.) changes in the installation site.
2. The alarm must be set within a range where the performance of the detector can be ensured.
In facilities compliant with the High Pressure Gas Safety Act, an alarm setting below our standard alarm
setpoint (threshold limit value) may trigger a false alarm.
3. If use in safety unit, the analog signal output of the detector must be used for an indicator or external
recorder.
If these outputs are used to control other units, we shall not be responsible for any malfunctions.
4. Because the contact point of the gas detector sensor is made of porous polymeric membrane, the water
repellency of the membrane is deteriorated by solvents, thus causing an electrolyte leak from its inside.
Do not use solvents near the detector. If a solvent is used for unavoidable reasons, attach the
recommended filter to the inlet of the gas detector while using the solvent and for one hour after that.
5. For maintenance of the detector, it must go through a regular maintenance, including replacement and
adjustment of the regular replacement parts as specified in the operating manual. In addition, because
this is a safety unit, it is recommended that a regular maintenance and a calibration are performed every
six months in accordance with the regulations.

2-2. Warning cases
WARNING
Power supply
Before turning on the detector, always check that the voltage is properly applied. Do not use an
unstable power supply because it may cause malfunctions.
Need of grounding circuit
Do not cut the grounding circuit or disconnect the wire from the grounding terminal.
Defects in protective functions
Before starting the detector, check the protective functions for defects. When seeming defects are
found in the protective functions, such as protective grounding, do not start the detector.
External connection
Before connecting the detector to the external control circuit, securely connect it to a protective
grounding circuit.
Tubing
The detector is designed to draw gases around it under the atmospheric pressure. Be sure that
excessive pressure is not applied to the sampling inlet and outlet (GAS IN, GAS OUT) of the
detector. Detected gases must be exhausted from the detected gas exhausting outlet (GAS OUT) to
which an exhaust tube is connected, to a point regarded as a safe place.
Zero adjustment in the atmosphere
When the zero adjustment is performed in the atmosphere, check the atmosphere for freshness
before beginning the adjustment. If interference gases exist, the adjustment cannot be performed
properly, thus leading to dangers when the gas leaks.
Response to gas alarm
Issuance of a gas alarm indicates that there are extreme dangers. Take proper actions based on
your judgment.
Handling of sensor
Do not disassemble the sensor used by the detector because it contains electrolyte. Electrolyte may
cause severe skin burns if it contacts skin, while it may cause blindness if its contacts eyes. If
electrolyte is adhered on your clothes, that part on your clothes is discolored or its material is
decomposed. If contact occurs, rinse the area immediately with a large quantity of water.

2 Important Notices on Safety 2-3. Precautions
- 6 -
2-3. Precautions
CAUTION
Do not use a transceiver near the detector.
Radio wave from a transceiver or other radio wave transmitting device near the detector or its
cables may disturb readings. If a transceiver or other radio wave transmitting device is used, it must
be used in a place where it disturbs nothing.
To restart the detector, wait for five seconds or more before doing it.
Restarting the detector in less than five seconds may cause errors.
Verify that the flow rate corresponds to the specified flow rate before using the detector.
If it does not correspond to the specified flow rate, gas detection cannot be performed properly.
Check whether the flow rate is unstable or lost.
Attach the dust filter before using the detector.
Before using the detector, attach the specified filter to prevent disturbances by possible gas
adsorption or air dust.
A dust filter to be used varies depending on the gas to be detected. For more information on dust
filters, please contact RIKEN KEIKI.
Observe the operating restrictions to prevent condensation inside the tube.
Condensation formed inside the tube causes clogging or gas adsorption, which may disturb
accurate gas detection. Thus, condensation must be avoided. In addition to the installation
environment, carefully monitor the temperature/humidity of the sampling point to prevent
condensation inside the tube. In particular, when detecting a gas which is dissolved into water and
corrodes contacted materials, such as a strong acid gas, the gas is undetectable and furthermore
may corrode internal parts. Please observe the operating restrictions.
Do not use the external output of the detector to control other units.
This is not a control unit. It is not allowed to use the external output of the detector to control other
units.
Do not disassemble/modify the detector, or change the settings if not necessary.
Disassembling/modifying the detector will invalidate the warranty of the performance. Changing the
settings without understanding the specifications may cause alarm malfunctions. Please use the
detector properly in accordance with the operating manual.
Avoid applying organic solvents and others to the window plate for a long time.
The window plate material is a polycarbonate resin. When organic solvents (liquid or
highly-concentrated vapor) and others are applied to the plate for a long time, its color and shape
may be changed.
Never fail to perform a regular maintenance.
Since this is a safety unit, a regular maintenance must be performed to ensure safety. Continuing to
use the detector without performing a maintenance will deteriorate the sensitivity of the sensor, thus
resulting in inaccurate gas detection.

<Export Specification> -10 to +40°C
<Japan Specification> -10 to +40°C
Do not install the detector in a place exposed to direct sunlight or sudden changes in the temperature.
When selecting installation points, avoid a place where it is exposed to direct sunlight or radiant heat
(infrared rays emitted from a high-temperature object), and where the temperature changes suddenly.
Condensation may be formed inside the detector, or the detector cannot adjust to sudden changes in the
temperature.
Keep the detector (and its cables) away from noise source devices.
When selecting installation points, avoid a place where high-frequency/high-voltage devices exist.
CAUTION
This is a precision device. Because the detector may not provide the specified performance in some
places (environments), check the environment in the installation point, and then take appropriate
actions if necessary.
Because the detector plays an important role for safety and disaster prevention, as many units of
the detector as needed must be installed in appropriate points.
Because points where gases leak and remain easily are different depending on the types of gases
and the working areas, please decide carefully on installation points and the number of units to be
installed.

4 How to Use 4-3. Precautions for system designing
- 13 -
Do not install the detector in a place where maintenance of the detector cannot be performed or where
handling the detector involves dangers.
Regular maintenance of the detector must be performed.
Do not install the detector in a place where the machinery must be stopped when maintenance is performed
in its inside, where parts of the machinery must be removed to perform maintenance, or where the detector
cannot be removed because tubes or racks prevent access to it. Do not install the detector in a place where
maintenance involves dangers, for example, near a high-voltage cable.
Do not install the detector in machinery which is not properly grounded.
Before installing the detector in machinery, the machinery must be grounded properly.
Do not install the detector in a place where interference gases exist around it.
The detector must not be installed in a place where interference gases exist around it.
4-3. Precautions for system designing
Using a stable power supply
The external output of the detector may be activated when the power is turned on, when momentary
blackout occurs, or while the system is being stabilized. In such cases, use a UPS (uninterruptible power
supply), or take appropriate actions on the receiving side.
The detector must be provided with the following power supply.
Power supply voltage 24 VDC±10%: Terminal voltage of the detector
Allowed time of
momentary blackout
Up to 10 milliseconds
(To recover from the momentary
blackout for 10 milliseconds or more,
restart the detector.)
Example of actions
To ensure continuous operation and
activation, install a UPS outside the
detector.
Others
Do not use it with a power supply of
large power load or high-frequency
noise.
Example of actions
Use a line filter to avoid the noise source
if necessary.
Introducing protective measures against lightning
If cables are installed outside the factory/plant, or if internal cables are installed in the same duct as the
cables coming from outside the factory/plant, "lightning" will cause problems. Because lightning acts as a
large emission source while cables act as a receiving antenna, devices connected to the cables may be
damaged.
Lightning cannot be prevented. Cables installed in a metal conduit or under the ground cannot be
completely protected from inductive lightning surge caused by lightning. Although complete elimination of
disasters caused by lightning is impossible, the following protective measures can be taken.
Protection against
lightning
Take appropriate measures in accordance with the importance of the facilities and the
environment.
Provide protection by a lightning arrester (cable arrester).
(Although inductive lightning surge can be transmitted through the cable, it is
prevented by installing a lightning arrester before the field devices and central
processing equipment. For information on how to use a lightning arrester,
please contact the manufacturer.)
Grounding In addition to lightning, there are more sources of surge noise. To protect units from
these noise sources, the units must be grounded.
* The lightning arrester has a circuit to remove a surge voltage which damages field devices, so that
signals may be attenuated. Before installing a lightning arrester, verify that it works properly.
CAUTION
An unstable power supply and noise may cause malfunctions or false alarms.
The descriptions in this section must be reflected on the designing of a system using the detector.
