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% O2 or 0 to 25% O2. (0 to 40% O2 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.

Remove power from the Oxymitter 4000 before changing defaults. If defaults are changed under power, damage to the electronics package may occur.

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.
