MODEL 5081-A
3.1
3.2
The Model 5081-A transmitter leaves the factory configured for use with the Model 499ADO sen-
sor (ppm dissolved oxygen). If a 499ADO sensor is not being used, turn to Section 7.5.3 and
configure the transmitter for the desired measurement (ppb oxygen, oxygen measured using a
steam-sterilizable sensor, free chlorine, total chlorine, or ozone) before wiring the sensor to the
transmitter. Operating the transmitter and sensor for longer than five minutes while the trans-
mitter is improperly configured will greatly increase the stabilization time for the sensor.
Be sure to turn off power to the transmitter before wiring the sensor.

3.1 WIRING MODEL 499A OxyGEN, CHLORINE, AND OzONE SENSORS

All 499A sensors (499ADO, 499ATrDO, 499ACL-01, 499ACL-02, and 499AOZ) have identical wiring.
Use the pigtail wire and wire nuts provided with the sensor when more than one wire must be attached to a single ter-
minal.
