Page 9: Section 2: Installation
Carefully remove all the components from the packaging and check them against the enclosed packing list. Inspect all components for any obvious damage such as broken or loose parts. If you find any components missing or damaged, notify the representative or Net Safety Monitoring immediately. 2.2 Mount The sensor is mounted directly to either transmitter housing or to a separation junction box housing through the ¾”... -

A B Earth Ground Ground NOTE: When separating sensor from transmitter using Net Safety separation kit, refer to Multi-purpose Junction Box Manual (MAN-0081) for terminal designations. SECTION 3: Operation 3.1 Configuration Settings All configuration settings are accessed through the Millennium II series transmitter. This is done by setting dip switches on the Millennium II Basic and by selecting menu options in the Millennium Transmitter. -
