Component Names of the High Pressure Side Transmitter (Master)
Note 1: See GS for details.
Note 2: Set the switches (BO, WR) as shown in the figure above to set the burn-out direction for CPU errors and write protection. The
Burnout switch is set to the H side for delivery (unless option code /C1 or /C2 is specified in the order), and the hardware write
protection switch is set to E side.
• The setting of the switches can be confirmed using the HART configuration tool. See subsections 7.2.3.12, “CPU Error Burnout
Switch and Hardware Write Protection, and 7.2.3.13, “Software Write Protection.”
• To disable zero point adjustment using the external zero-adjustment screw, see subsection 7.2.3.11, “External Switch Mode.”
