4.1 Notes on Selecting the Installation Location
This product is designed for the following environment.
• Indoor and outdoor installation • Ambient temperature: —20 to +60°C
• Altitude: Up to 2000m • Humidity range: 10 to 90%(no condensation)
• Regulation of power voltage: ± 10%
• Pollution degree 2 • Structure: IP67 (NEMA 4X)
□
Do not store or install the flowmeter in :
1. Places within the immediate proximity of equipment producing electrical interference (such as
motors, transformers, radio transmitters, electrolytic cells, or other equipment causing
electromagnetic or electrostatic interference).
2. Places where there is direct sunlight.
3. Places where excessive vibration or mechanical shock occurs.
4. Places where high temperature or high humidity conditions obtain.
5. Places where corrosive atmospheres obtain.
6. Places submerged under water.
7. Place where there is slop floor. To put the flowmeter temporarily on the floor, place it
carefully with something, such as stopper, to support it so that the flowmeter will not
topple over.
8. Places of too great an elevation or constricted areas where clearance for installation or
maintenance work is not provided.
9. The standard length of the cable that connects the detector and converter is 30m. Select the
converter installation location so that the distance of the detector and converter will not exceed
LF602F 30m.
10. Places where there is following factors.
♦ Factors to impede infrared switch to operate properly
• Intense light such as direct sunlight and reflected sunlight by window glass or metal plate
• Place where brightness changes always such as ON/OFF of lighting
• Dense smoke or steam near the control panel
• Those attached on the control panel such as rain (dew drop), snow, ice, mud and oil, and haze due
to their attachment
• Light reflecting object near the control panel, or reflecting object such as metal plate placed
opposing to the control panel
When any of above factors is considered, take a measure for the proper operation of infrared switch
such as to place a cover or to secure a space for at least a person to stand in front of the control
panel.
When unable to avoid above factors, operate the EMF converter removing the factor by covering
the control panel by hand so that light does not shine on it, by cleaning those attached on the control
panel, or by standing in-between the reflecting object and the control panel to block the light.
