	WIRING

NOTE

The Model 54eA analyzer leaves the factory configured for use with the Model 499ADO sensor (ppm dissolved oxygen). If a 499ADO sensor is not being used, turn to Section 5.5 and config- ure the analyzer for the desired measurement (ppb oxygen, oxygen measured using a steam- sterilizable sensor, free chlorine, total chlorine, monochloramine, or ozone) before wiring the sensor to the analyzer. Operating the analyzer and sensor for longer than five minutes while the analyzer is improperly configured will greatly increase the stabilization time for the sensor.

Be sure to turn off power to the analyzer before wiring the sensor.

3.3 SENSOR WIRING

3.3.1 General

The wiring label, which is shown in Figure 3-2, is a general purpose label. It has wiring infor- mation concerning other sensors, for example, contacting and inductive conductivity sensors, that can be used with the 54e instrument plat- form. For amperometric measurements, only TB3 and TB5 are used. Wire the amperometric sensor to TB3. Wire the pH sensor, if one is being used, to TB5.

3.3.2Wiring Model 499A oxygen, chlorine, and ozone sensors

All 499A amperometric sensors (499ATrDO, 499ADO, 499ACL-01, 499ACL-02, 499ACL-03, and 499AOZ) have identical wiring.

Use the pigtail wire and wire nuts provided with the amperometric sensor when more than one wire must be attached to a single terminal.

See Figures 3-3 and 3-4.
