Troubleshooting continued
For hazardous area installation in Europe, use standard EN 60079-14 as
a guideline if national standards are not in effect.
Sensor grounding screw
Checking for moisture in the core processor or sensor junction box
Note that the following will help reduce the risk of getting moisture in the
core processor or sensor junction box: If possible, install wiring with the
conduit openings pointed down to reduce the risk of condensation or
moisture in the housing. Otherwise, install drip legs on the cable or
conduit.
All wiring compartments must be sealed to prevent a short circuit. A
short would result in measurement error or flowmeter failure.
• The D600 has a junction box and a booster amplifier housing.
• Do not open the D600 booster amplifier housing while the booster
amplifier is energized. See the warning statement below.
• Replace all covers and seal all openings before applying power to a
D600 sensor.
