Figure A - 7 Example of HART Supported Wiring
NOTE: Use supplied green conductor for enclosure ground.
NOTE: The is a 3- or 4-wire 4-20mA device. For dual sensor
configuration you must have a second 4-20mA signal wire pulled to the unit.
NOTE: When not using isolated 4-20mA or HART 4-20mA outputs, use the
supplied resistors to connect CH-1 and CH-2 to GND. If these resistors are
not connected and the 4-20mA outputs are not used, a “P” will appear on
the display, indicating an open loop condition.
IMPORTANT: In Chapter 4 |, the “Digital ModBus RTU Interface Wiring”
section is not applicable for HART supported as ModBus interface is
not available on HART supported unit.
