IM-106-880, Rev 1.0 January 2007

Verify Configuration

There are three switches on the microprocessor board which are user configurable for the OCX 8800 (Figure 3-1). SW1 determines if the O2 4-20 mA signal is internally or externally powered. SW2 determines if the COe 4-20 mA signal is internally or externally powered. SW3 sets the rail limits for the O2 and COe 4-20 mA signals and configures the sample line heater control circuit. All switches are accessible through holes in the electronics box.

Remove power from the OCX 8800 before changing defaults. If defaults are changed under power, damage to the electronics may occur.

Verify that the following switch settings are correct for your OCX 8800 installation:

SW1 The two settings are internally or externally powering the O2 4-20 mA signal. The factory setting is for the O2 4-20 mA signal to be internally powered.

SW2 The two settings are internally or externally powering the COe 4-20 mA signal. The factory setting is for the COe 4-20 mA signal to be internally powered.

SW3 The factory sets this switch as follows:

•Position 1 determines the O2 4-20 mA signal rail limit. The settings are high, 21.1 mA, or low, 3.5 mA. The factory setting is low, 3.5 mA.

•Position 2 determines the COe 4-20 mA signal rail limit. The settings are high, 21.1 mA, or low, 3.5 mA. The factory setting is high, 21.1 mA.

•Positions 3 and 4 must be set as shown for proper software control of the device heaters.
