Installation and maintenance
Installation suggestions:
Installed vertically in the metal control cabinet,≥50mm away from the heat source.
The wiring is made of shielded twisted pair wires,and the length of a single wire is≤100 meters(HART protocol).
Maintenance cycle:
Check channel drift every quarter(standard:≤0.1%FS).
Test insulation resistance every year(required≥100MΩ).
Troubleshooting:
If the HART signal is abnormal,priority is given to check the terminal resistance matching(standard:250Ω).
High humidity environments require detection of the output voltage of the power module(requires 24±0.5V DC).
