CAUTION
• The sensor unit must be handled carefully to ensure quality as safety device. When the sensor unit is
stored, a dedicated warehouse and power equipment for the sensor unit are needed. In principal, the
sensor unit must not be detached from the detector when it is handled or stored. We will take care of
your sensor unit.
• Be sure that the sensor unit is not installed improperly.
If a sensor unit of different specification or principle from the one shipped from the manufacturer, a
message will be displayed on the LCD of the detector (C-02).
If the message is displayed, check the specifications of the sensor unit.
• After the sensor unit is replaced, always perform a gas calibration (zero adjustment and span
adjustment).
<How to Use Sensor Unit>
A sensor unit installed in the detector is the same regardless of
the detection principle, thus sensor units are interchangeable.
Each sensor unit has a different color in accordance with the
principle as shown below. How to handle the sensor unit is varies
depending on its principle.
Electrochemical
type (ESU)
• Do not disassemble the sensor unit because it contains electrolyte. If contact
occurs, rinse the area immediately with a large quantity of water.
• The sensor unit identifies the direction. Put the sensor unit in the dedicated case
while handling it. Do not place it on its side or upside-down.
• When a new sensor unit is installed, it must be warmed up.
Although warm-up time is different depending on the type of the installed sensor,
it is recommended that warm-up should be performed for three hours or more.
Please contact our sales department for more
information.
• The sensor unit must be stored in a clean, cool and
dark place away from direct sunlight. Some types of
the sensor units cannot be stored together with other
units. Please contact our sales department for more
information.
Pyrolysis-particle
type (SSU)
• Although the sensor unit contains radioactive materials, it is certified as a
specified designing certification device, which is regarded as a device having
no influences on health. Observe the "Safety Manual" which stipulates
conditions for the certification. To dispose of the sensor unit, you must return
it to us. You do not need to take any additional actions.
• The sensor unit contains a small amount of radioactive materials. Do not
disassemble it, or dispose of it like other wastes.
• The sensor unit must be put into the dedicated case specified by us, and
stored away from direct sunlight in a clean place
where the temperature and humidity are maintained
at a normal level and where appropriate measures
are introduced to prevent it from being taken out
easily.
• When the sensor unit is transported out of your
factory, please use a transportation company which
can handle specified designing certification devices
(L-type packages).
• For more information, see the "Safety Manual".
