Section 3: Operation

3.1

Sensor configuration settings

All configuration settings for the SC311 sensor are accessed through the Millennium II series of
transmitters. When using the Millennium II Transmitter, configuration settings are accessed by
selecting menu options through the main display.
Tip
Refer to the relevant transmitter manual prior to attempting a
calibration.
3.2

Sensor power up

When power is applied to the sensor by the transmitter, a warm-up routine will begin and the sensor
will be automatically tested to ensure proper functioning. The warm-up time for the SC311 sensor is
typically ninety (90) seconds. Refer to the Millennium II transmitter manual (MAN-0076) or the Net
Safety Millennium II Basic transmitter manual (MAN-0082) for status indicators during this period.
3.3

Sensor communication

The SC311 sensor uses a proprietary protocol to communicate with the Millennium II series of
transmitters. This sensor should never be connected to any device other than the Millennium II series
of transmitters. Selected DIP switches and menu options allow communication between the
transmitter and sensor. Configuration settings are stored in the memory of the sensor. Incorrect
settings will cause the sensor to not communicate properly with the transmitter. If any problems
develop, please refer to the troubleshooting section of this manual.
