Eaton EMR-3MP0 User Manual

• A general overview of the protection functions available with the EMR-3MP0 can be
found as a function diagram: ╚═▷ “1 Functional Overview”. Note that the availability
of some functions depends on the ordered device type. See ╚═▷ “Catalog Codes for
the EMR-3MP0” for the available variants.
• The EMR-3MP0 uses a special modular concept for its settings, measured values and
signals. Although this concept of modules and parameters is simple and straight-
forward it is strongly recommended, especially for beginners, to make oneself
familiar with it: ╚═▷ “Modules, Settings, Signals and Values”
•
PowerPort-E is the operating program that can be installed on a Windows PC. It can
connect to the EMR-3MP0, and it can be used to do con󰊎guration work and retrieve
data from the EMR-3MP0. A few introductory words are here: ╚═▷ “PowerPort-E”;
however, for a detailed description you can consult the full PowerPort-E Manual as a
separate document.
• The hardware aspects (e. g. dimension diagrams and connection diagrams) can be
found here: ╚═▷ “Hardware”
• Various Security settings might have to be done, because the EMR-3MP0 is delivered
with no access restrictions and a very simple standard password that does not o󰊍er
any safety at all. Unless you are sure that no special access restrictions are required
for your application, it is strictly recommended to check the “Security” chapter: ╚═▷
“Security”
• A few settings are related to the EMR-3MP0 itself: ╚═▷ “Device Parameters”
• The various communication protocols that the EMR-3MP0 makes available for
communicating with the substation are described in ╚═▷ “Communication Protocols”.
•
The multitude of protection functions is described in sub-chapters within the
“Protection Functions” chapter: ╚═▷ “Protective Elements”. Keep in mind that there is
one “master protection” module that governs all protection functions: ╚═▷
“Protection (Prot) Module”. And furthermore, it is not only important to know how to
activate a protection module, it is also essential to know about the blocking of a
module: ╚═▷ “Blockings”
• Various kinds of events (disturbances, detected faults, etc.) are recorded by the
EMR-3MP0, so that you need to know how to access these records: ╚═▷ “Recorders”
• The EMR-3MP0 o󰊍ers programmable logic equations for programming inputs,
outputs, blocking of protective functions, and custom logic functions in the relay:
╚═▷ “Programmable Logic”
• Commissioning aspects for the EMR-3MP0: ╚═▷ “Commissioning”. But note that
protection-speci󰊎c commissioning descriptions are sub-chapters within the
respective chapters for the protection functions.
• Technical data, tolerances, and applicable standards: ╚═▷ “Technical Data
EMR-3MP0”
