1.1 About this Manual

This manual introduces you to the Siemens Advanced Motor Master System (SAMMS-MVä) motor protection and control relay which incorporates protection designed for medium voltage machines. This manual also contains information for installing and operating the device, communicating with other devices over the ACCESSä electrical distribution communica- tions system, and troubleshooting the device. This manual also provides a helpful technical reference for you to use. Refer to table 1.1 to determine which section of the manual contains the information that you need.

These instructions prepare you to handle, install, operate and maintain the SAMMS-MV device and the Hand-Held Commu- nicator (HHC). The individual starters and controllers used are designed for specific applications based upon your equipment and needs. Instructions covering these starters and compo- nents are not included in this manual. For this information, refer to instructions and drawings furnished with your equipment, or contact your Siemens representative. You must read these instructions and determine applicability of your equipment. Refer to the nameplate data on your controller and to the electrical diagrams supplied with your controller to determine applicability of your equipment.

1.2 About the SAMMS-MV Device

The SAMMS-MV device, shown in Figure 1.1, is a software- configured electronic motor control and overload protection device that incorporates protection tailored to the special characteristics of medium voltage motors. The SAMMS-MV system includes a microprocessor-based SAMMS-MV device which receives signal inputs from a set of current transformers (either 3-1Ø or 1-3Ø) and power input from a 12 volt tap on the controller’s control power transformer. To perform certain monitoring and setup activities, a Hand-Held Communicator (HHC) shown in Figure 1.2, is required. The SAMMS-MV device is a multi-functional device offering the following:

•advanced motor protection for medium voltage motors

•pre-programmed control circuits

•standardized control panel with input/output devices replac- ing conventional push-buttons, pilot lights and selector switches

•diagnostics

•statistical motor data

•real-time metering

•local display of all motor and control circuit data

•open architecture communications using the ACCESS sys- tem

Note: The SAMMS-MV device does not replace the disconnect device (drawout contactor mounting or isolating switch) or the contactor itself.
