Operating Precautions
This detector is an oxygen deficiency detector that detects oxygen in the air and triggers an oxygen
deficiency alarm.
The oxygen deficiency detector is a safety unit, not an analyzer or densitometer which performs
quantitative/qualitative analysis/measurement for oxygen.
Please fully understand the following points before using it, so that it can be used properly.
1. The readings of the detector fluctuate slightly in response to changes in the air pressure.
In particular, be careful of alarm activation when a low air pressure is brought in by typhoon. 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.
The standard alarm setpoint value is 18 vol%.
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.
If use as safety instrumentation device, determine the specification and manage it based on the safety
manual.
4. 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 span adjustment are performed
every six months.
5. This detector is SIL2 ceritified for single application. SIL 2 is Safety Integrity Level by safety
instrumentation functioning omni-PFD avg .If use as safety instrumentation device, determine the
specification and manage it based on the safety manual.

Outline of the Product
1-1. Preface
Thank you for choosing our smart transmitter/gas detector head SD-1OX(TYPE HS). Please check that the
model number of the product you purchased is included in the specifications on this manual.
This manual explains how to use the detector and its specifications. It contains information required for
using the gas detector properly. Not only the first-time users but also the users who have already used the
product must read and understand the operating manual to enhance the knowledge and experience before
using the detector.
1-2. Purpose of use
This detector is a fixed type gas detector head that detects oxygen and performs the alarm activation
when the gas concentration is over the setting value.
The detector detects abnormalities in the air caused by presence of gases or other reasons (leak) with
the built-in gas sensor. The concentrations of detected gases are displayed on the seven-segment
LED.
The detector outputs gas concentration in 4 – 20 mA.
The detector has HART communication function.
The detector is a safety unit, not an analyzer or densitometer which performs quantitative/qualitative
analysis/measurement for gases. Please fully understand the features of the detector before using it,
so that it can be used properly.
