After HART communication has been established with the PIRECL, the following operational parameters are generally
verified:
1. Inspect the Root menu to confirm that the gas type selected is proper for the gas hazard to be detected. The
PIRECL is shipped from the factory calibrated and set for detection of methane, propane, ethylene, or butane. If a
different gas type is desired, then change the setting using the detailed setup programming option, and perform
a field calibration using the same gas type as is selected. Refer to the Calibration section of this manual.
2. Inspect the Gas Alarm level thresholds and Fault output signals using the Detailed setup option, and modify these
settings if required.
3. Enter a device Tag number and/or descriptor for future traceability and guidance.
While these three operations are typical, these steps may not be satisfactory for your application.
The following data provides basic guidance on HART menu navigation. Refer to the HART Field Communicator manual
for additional guidance.
online MenU
When HART communication is established with the PIRECL, the first menu displayed is the 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.
1 Device setup
Press to access the Device Setup menu from the Online menu. The Device Setup menu
accesses every configurable parameter of the connected device. Refer to the Device Setup
SubMenu for more information.
2 Gas
This shows gas type selected for detection.
3 pv (primary variable)
This shows the gas concentration being detected in %LEL.
4 pv Ao (Analog output)
This shows the Analog output level in selected units, typically milliamperes.
5 pv Urv (Upper range value)
Select URV to view the upper range value and related engineering units.
