Configuration Located on the microprocessor board are two switches that configure outputs
(Figure 4-2). To access these switches, the LOI module must be removed.
SW1 determines if the 4-20 mA signal is internally or externally powered.
SW2 determines:
1. Range control, HART or LOCAL.
2. Oxygen range, 0 to 10% O
2
or 0 to 25% O
2
. (0 to 40% O
2
is also
configurable only through HART/AMS.)
3. The 4-20 mA signal, at fault or power up, 3.5 mA or 21.6 mA.
SW1 Setting
The two settings are internally or externally powering the 4-20 mA signal. The
factory setting is for the 4-20 mA signal to be internally powered.
