used

■ Precautions

1. Avoid use in excessively dirty, wet environments

2. Do not use in the presence of flammable gases (e.g. hydrogen,

methane, ethane) and liquefied petroleum gas. In addition, do not

use with corrosive gases (e.g. chlorine, sulphur, acids, alkalis,

etc.).

3. Install in the direction of the arrow indicated.

4. For best results (optimum accuracy), mount horizontally.

5. Use four suitable M3 screws for mounting. Do not exceed a fixing

torque of 0.59 Nm.

6. Do not modify D6F- in any way.

7. Do not place any object in or close to the inlet and outlet orifices.

8. Do not use the sensor in any of the following environments:

• a location that receives radiant heat from the sun or apparatus

• a place where intense light may radiate down

• places where corrosive gas, especially sulphur and ammonia

gases are present

• where fast changing temperatures occur

• locations prone to freezing, high humidity, condensation

• places where large magnitudes of vibration or shock could occur

9. Noise countermeasures: VERY IMPORTANT: Take suitable pre-

cautions to minimize the effects and potential for induced electri-

cal noise. Install away from apparatus that generates strong high

frequencies, surges and spikes. Take particular care to install

away from AC power transformers, live mains power lines and

high power magnetic circuits. Attach a surge suppressor and a

noise filter to the peripheral equipment.

10.Ensure good grounding is achieved by grounding the GND termi-

nal to the peripheral equipment’s main ground frame connection

and its associated regulated power supply.

11.Do not make a direct solder connection to the integral terminals. It

is recommended you use the optional cable ‘D6F-CABLE1’ for

attachment and to ensure correct connection.

12.D6F- is a precision component. Keep in original packaging and

remove only when ready for installation. Damage may occur if

subjected to excessive force (e.g. dropped or kicked). Any item

suspected to be damaged should be discarded.

13.Immediately following installation, a qualified person should per-

form checks to ensure safe, satisfactory operation.
