• Check wire insulation for possible short circuits to ground
• Check that there are no multiple shield grounding points
• Check that the cable shield is grounded at the power supply
end only
• Check that the cable shield is continuous throughout the
fieldbus network
• Check that the shield inside the instrument housing does
not come into contact with the housing
• Check that there is no water in conduits
• Use shielded twisted pair wiring
• Connect wiring with drip loops
Cables are too long
• Check that the input voltage on the device terminal is 9 V or
more
Hardware failure
• Check the 2230 Display if other devices such as the 2410
Tank Hub are detected by the host system. In a
FOUNDATION fieldbus system you can check the Device Live
List to confirm that the host can detect other devices.
