CONNECTIONS AND HARDWARE
The HART Communicator can interface with the LS2000 from the control room or from any
wiring termination point in the analog output signal loop. To communicate, connect the HART
communicator in parallel with the LS2000 analog signal or load resistor. The connections are non-
polarized. Refer to the “Wiring Procedure” section for installation instructions.
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 LS2000
Online menu:
To select any of the 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 LS2000 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 temperature,
calibration and event logs.
