WARNING
Handling of sensor
Do not disassemble the sensor unit because it contains electrolyte. If contact occurs, rinse the
area immediately with a large quantity of water.
Calibration
When performing calibration for the detector head, be careful of loose tubes, etc. to prevent
personnel from contacting gases.
Response to gas detection
When a gas is detected, it indicates a potentially dangerous situation. Take proper actions based
on your judgment.
2-3. Precautions
CAUTION
Do not use a transceiver near the detector head.
Radio wave from a transceiver etc. near the detector head or its cables may disturb indication
reading. 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 the detector head, wait for five seconds or more before doing it.
Restarting the detector head within five seconds may cause errors.
Careful consideration should be given to instrumentation to maintain safety even when a trouble
like disconnection of power/signal cable or unexpected malfunction or failure occurs.
This is an electrical appliance. Be careful that it may be affected, in rare cases, by power supply
noises, static electricity, and electromagnetic noises. Before using the detector head in an
environment with such noises, provide for protective measures against them.
2-4. Operating Precautions
This product is a gas detector that detects oxygen in the air and outputs gas concentration signals.
The detector head 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 readings of the detector head 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. This is a safety unit, not a control unit.
Use the analog signal output of the detector head for an indicator or external recorder.
If these outputs are used to control other units, we shall not be responsible for any malfunctions.
3. For maintenance of the detector head, 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 regular maintenance and span adjustment be performed every
six months.
