CONNECTIONS AND HARDWARE
The HART Communicator can interface with the Open Path Eclipse from the onboard I.S. communication port,
from the control room, or from any wiring termination point in the analog output signal loop. To communicate, con-
nect the HART communicator in parallel with the Open Path Eclipse analog signal or load resistor. The connec-
tions are non-polarized.
NOTE
The HART Communicator needs a minimum of 250 ohms resistance in the loop to function properly. The
HART Communicator does not measure loop current directly.
ONLINE MENU
When HART communication is established with the receiver, the first menu displayed is the OPGD RX Root menu:
To select any of the 5 menu options shown, highlight the desired option using the up/down arrow key, and then
press the “right arrow” key.
COMMONLY USED HART COMMANDS
The most commonly used HART commands for the Model OPECL are:
1. Setting the real time clock
2. Setting alarm thresholds & latch/nonlatch functions
3. Setting the analog fault code menu
4. Performing full system alignment
5. Performing zero calibration
6. Assigning a nonvolatile tag name to the receiver
7. Defining a nonvolatile descriptor for future reference
8. Interrogating the history menu for information including total running hours, max/min exposed temperature,
calibration and event logs.
