3. 3. 3. 3. SETTINGS SETTINGS SETTINGS SETTINGS
This section describes the settings incorporated in the SMOR unit, and the procedure for changing them.
First a complete list of the SMOR settings is shown, together with their limits, units and corresponding steps
(the column marked DEFAULT indicates that this is the setting on the relay when it leaves the factory). This
is followed by individual comments for those settings which require more detailed explanation.
It is possible to see the settings or to modify them manually, using the keyboard and display, or by means of
a computer connected to any of the serial ports. To modify the settings by means of the keyboard, go to
section 8 "KEYBOARD AND DISPLAY". To modify the settings by computer follow these instructions:
• Make sure that the available connection cable coincides with the diagram in figure 8, depending on
whether the serial port of your computer is DB9 or DB25.
• Connect the cable between the relay (or modem) and the serial port of your computer.
• Run the GE-LOCAL software. For more details on the installation and use of the GE-LOCAL software
see the GE-LOCAL instruction book.
• Make sure that the program configuration communication parameters coincide with those of the SMOR
unit. More specifically, these parameters for the communication configuration of the local MMI are as
follows:
- COMMUNICATION BAUD RATE (for the relay depending on which port is being used (local or
remote))
- STOP BIT (for the relay depending on which port is being used (local or remote))
To modify or view the unit's configuration parameters go to the configuration menu, corresponding to section
8 "KEYBOARD AND DISPLAY".
When connecting to the unit, check that the relay number and password coincide with those which appear on
the unit's configuration menu.
The SMOR system has 3 settings tables stored in non-volatile memory, and these can be selected by
settings or configurable inputs. There is also a set of independent settings, common to all the tables. The
following categories contain the settings common to the 3 tables:
GENERAL
BREAKER
ACTIVE TABLE
OSCILLOGRAPHY
PERMISSIONS FOR EACH FUNCTION
The remaining categories, shown below, contain the settings which can be selected independently for each
of the 3 tables:
• Function 51 PT (Phase Time delayed overcurrent (Inverse or definite time))
• Function 51 NT (Ground Time delayed overcurrent (Inverse or definite time))
• Function 50 PH (High Phase instantaneous level (can be definite time))
• Function 50 PL (Low Phase instantaneous level (can be definite time))
• Function 50 NH (High Ground instantaneous level (can be definite time))
• Function 50 NL (Low Ground instantaneous level (can be definite time))
• Function 46 PT (Negative sequence (Inverse or definite time))
• Function 81O/U (Frequency)
• Function 27/59P/59NH/59NL (Voltage)
• Directionality
• Recloser
It should be noted that in order to simplify setting the unit and for safety reasons, all settings related to the
configuration of the unit (configurable inputs and outputs, alarms configuration and LEDs) have been
