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
heater control 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.
