Oxymitter 4000
Configuration Located on the microprocessor board, the top board, are two switches that
configure outputs for the Oxymitter 4000 (Figure 3-2). SW1 determines if the
4-20 mA signal is internally or externally powered. SW2 determines:
1. Oxymitter 4000 status, 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.
