Verify installation
Ensure that the transmitter is installed correctly. Verify mechanical installation and all
electrical and pneumatic connections.
Refer to Install.
CAUTION
Equipment damage
Damage can result from having a cold transmitter exposed to the process gases.
Make sure that the transmitter is turned on and operating prior to firing up the
combustion process.
During outages and whenever possible, leave all transmitters running to prevent
condensation and premature aging from thermal cycling.
3.1.1
Verify configuration - HART
There are three switches on the microprocessor board which are user configurable for the
Rosemount OCX8800 with HART electronics
SW1 determines if the O
determines if the COe 4-20 mA signal is internally or externally powered. SW3 sets the
rail limits for the O
circuit. All switches are accessible through holes in the electronics box.
CAUTION
Equipment damage
If defaults are changed under power, damage to the electronics may occur.
Remove power from the transmitter before changing defaults.
Verify that the following switch settings are correct for your installation.
