Siemens MCC-3298 Manual De Usuario

1 Introduction

1.1 About this Manual

This manual introduces you to the Siemens Advanced Motor

Master System (SAMMS-LV) motor protection and control relay

which incorporates protection designed for low voltage motors.

This manual also contains information for installing and operat-

ing the device, communicating with other devices over the

ACCESS



electrical distribution communications 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-LV 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-LV Device

The SAMMS-LV 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 low voltage motors. The SAMMS-LV system

includes a microprocessor-based SAMMS-LV 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

controllers control power transformer. To perform certain

monitoring and setup activities, a Hand-Held Communicator

(HHC) shown in Figure 1.2, is required. The SAMMS-LV device

is a multi-functional device offering the following:

advanced motor protection for low 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-LV device does not replace the disconnect

device or the contactor itself.
