This ‘path representation’ illustrates the location of an specific actual value or
setpoint with regards to its previous menus and sub-menus. In the example above,
the AVERAGE MOTOR LOAD LEARNED actual value is shown to be an item in the AVERAGE
MOTOR LOAD sub-menu, which itself is an item in the A3 LEARNED DATA menu, which is
an item of ACTUAL VALUES.
Sub-menu levels are entered by pressing the MESSAGE Xor ENTER key. When inside a
submenu, the WMESSAGE or ESCAPE key returns to the previous sub-menu. The
MESSAGE Tand MESSAGE Skeys are used to scroll through the settings in a sub-
menu. The display indicates which keys can be used at any given point.
Using the Relay
Menu Navigation The relay has three types of display messages: actual value, setpoint, and target
messages. A summary of the menu structure for setpoints and actual values can be
found at the beginning of chapters 5 and 6, respectively.
Setpoints are programmable settings entered by the user. These types of messages
are located within a menu structure that groups the information into categories.
Navigating the menu structure is described below.

1. Motor and System Status:
a. Motor status either stopped, starting, or running. It includes values such as
motor load, thermal capacity used, motor speed, and instantaneous values
of power system quantities.
b. The status of digital inputs.
c. Last trip information, including values such as cause of last trip, time and
date of trip, motor speed and load at the time of trip, pre-trip temperature
measurements, pre-trip analog inputs values, and pre-trip instantaneous
values of power system quantities.
d. Active alarms.
e. Relay date and time.
f. Present blocking conditions.
g. General system status indication including the status of output relays,
active pickup, alarm and trip conditions.
2. Metering Data:
a. Instantaneous current measurements including phase, differential, unbal-
ance, ground, average, and motor load.
b. RTD Temperatures including hottest RTDs.
c. Instantaneous phase to phase and phase to ground voltages (depending on
the VT connections), average voltage, and system frequency.
d. Motor Speed
e. Power Quantities including apparent, real and reactive power.

Changing Setpoints
Introduction There are several classes of setpoints, each distinguished by the way their values
are displayed and edited.
The relay's menu is arranged in a tree structure. Each setting in the menu is
referred to as a setpoint, and each setpoint in the menu may be accessed as
described in the previous section.
The settings are arranged in pages with each page containing related settings; for
example, all the Short Circuit Trip settings are contained within the same page. As
previously explained, the top menu page of each setting group describes the
settings contained within that page. Pressing the MESSAGE keys allows the user to
move between these top menus.
All of the 469 settings fall into one of following categories: device settings, system
settings, digital input settings, output relay settings, thermal model settings,
current element settings, motor starting settings, RTD temperatures settings,
voltage element settings, power element settings, monitoring settings, analog
input/output settings, two speed motor settings, and testing settings.
IMPORTANT NOTE: Settings are stored and used by the relay immediately
after they are entered. As such, caution must be exercised when entering
settings while the relay is in service. Modifying or storing protection
settings is not recommended when the relay is in service since any
incompatibility or lack of coordination with other previously saved settings
may cause unwanted operations.
Now that we have become more familiar with maneuvering through messages, we
can learn how to edit the values used by all setpoint classes.
Hardware and passcode security features are designed to provide protection against
unauthorized setpoint changes. Since we will be programming new setpoints using
the front panel keys, a hardware jumper must be installed across the setpoint
access terminals (C1 and C2) on the back of the relay case. Attempts to enter a new
setpoint without this electrical connection will result in an error message.
The jumper does not restrict setpoint access via serial communications. The relay
has a programmable passcode setpoint, which may be used to disallow setpoint
changes from both the front panel and the serial communications ports. This
passcode consists of up to eight (8) alphanumeric characters.
The factory default passcode is “0”. When this specific value is programmed into the
relay it has the effect of removing all setpoint modification restrictions. Therefore,
only the setpoint access jumper can be used to restrict setpoint access via the front
panel and there are no restrictions via the communications ports.
When the passcode is programmed to any other value, setpoint access is restricted
for the front panel and all communications ports. Access is not permitted until the
passcode is entered via the keypad or is programmed into a specific register (via
communications). Note that enabling setpoint access on one interface does not
automatically enable access for any of the other interfaces (i.e., the passcode must
be explicitly set in the relay via the interface from which access is desired).
A front panel command can disable setpoint access once all modifications are
complete. For the communications ports, writing an invalid passcode into the
register previously used to enable setpoint access disables access. In addition,
setpoint access is automatically disabled on an interface if no activity is detected for
thirty minutes.
The EnerVista 469 Setup software incorporates a facility for programming the
relay's passcode as well as enabling and disabling setpoint access. For example,
when an attempt is made to modify a setpoint but access is restricted, the software
will prompt the user to enter the passcode and send it to the relay before the
setpoint is actually written to the relay. If a SCADA system is used for relay
programming, it is the programmer's responsibility to incorporate appropriate
security for the application.

The HELP Key Pressing the HELP key displays context-sensitive information about setpoints such as
the range of values and the method of changing the setpoint. Help messages will
automatically scroll through all messages currently appropriate.
Numerical Setpoints Each numerical setpoint has its own minimum, maximum, and step value. These
parameters define the acceptable setpoint value range. Two methods of editing and
storing a numerical setpoint value are available.
The first method uses the 469 numeric keypad in the same way as any electronic
calculator. A number is entered one digit at a time with the 0 to 9 and decimal keys.
The left-most digit is entered first and the right-most digit is entered last. Pressing
ESCAPE before the ENTER key returns the original value to the display.
The second method uses the VA L U E Skey to increment the displayed value by the
step value, up to a maximum allowed value. Likewise, the VA L U E Tkey decrements
the displayed value by the step value, down to a minimum value. For example:
1. Select the S2 SYSTEM SETUP ZV VOLTAGE SENSING ZMOTOR NAMEPLATE VOLTAGE
setpoint message.
2. Press the 1, 3, 8, 0, and 0 keys. The display message will change as shown.
3. Until the ENTER key is pressed, editing changes are not registered by the relay.
Therefore, press the ENTER key to store the new value in memory. This flash
message will momentarily appear as confirmation of the storing process.

Output Relay Setpoints Output relays (Trip or Alarm) can be associated to the Auxiliary Relays 2 and 3. Each
can be selected individually, or in combination, in response to customer specific
requirements, which can be initiated by any protection element or function, whose
ASSIGN RELAYS setpoint has them selected.
1. Select the S5 CURRENT ELEM. ZSHORT CIRCUIT TRIP ZV ASSIGN TRIP RELAYS setpoint
message.
2. If an application requires the short circuit protection element to operate the
Auxiliary Output 3 relay, select this output relay by pressing the value key until
the desired combination appear in the display.
3. Press the ENTER key to store this change into memory. As before, confirmation of
this action will momentarily flash on the display.
Text Setpoints Text setpoints have data values, which are fixed in length, but user defined in
character. They may be comprised of uppercase letters, lowercase letters, numerals,
and a selection of special characters. The editing and storing of a text value is
accomplished with the use of the decimal [.], VA L U E , and ENTER keys.
For example:
1. Move to message S3 DIGITAL INPUTS ZV ASSIGNABLE INPUT 1 ZINPUT 1 FUNCTION,
and scrolling with the VALUE keys, select “General Sw. A”. The relay will display
the following message:
2. Press the MESSAGE Tkey to view the next setpoint, SWITCH NAME. The name of
this user defined input will be changed in this example from the generic
“General Sw. A” to something more descriptive.
3. If an application is to be using the relay as a station monitor, it is more
informative to rename this input “Station Monitor”. Press the decimal [.] key to
enter the text editing mode. The first character will appear underlined as
follows:.
4. Press the VA L U E keys until the character “S” is displayed in the first position. Now
press the decimal [.] key to store the character and advance the cursor to the
next position. Change the second character to a “t” in the same manner.
Continue entering characters in this way until all characters of the text “Stn.
Monitor” are entered. Note that a space is selected like a character. If a
character is entered incorrectly, press the decimal [.] key repeatedly until the
cursor returns to the position of the error. Re-enter the character as required.
Once complete, press the ENTER key to remove the solid cursor and view the
result. Once a character is entered, by pressing the ENTER key, it is automatically
saved in flash memory, as a new setpoint.

Application Example
Description The 469 Motor Management Relay contains many features designed to
accommodate a wide range of motor management applications. This chapter is
provided to guide you, the first time user, through a real-world application.
The following is typical example of how to determine the relay setpoints for a
specific motor that has been applied conservatively. This is only an example and
may not address all issues relating to your specific application. It is recommended
that your local protection engineer determine the setpoints for your motor
protective relaying application. Refer to following figures for schematic diagrams
related to this example.
Important points to keep in mind before developing settings for any multifunction
numerical device like the 469 Motor Management Relay:
• Gather system data, including, but not limited to:
– CT primary and secondary ratings for all the CTs used to feed the relay
– motor name plate data
– motor operating curves (typical set shown below)
FIGURE 1–1: Typical Motor Curves
– VT primary and secondary ratings
– System frequency
– System phase sequence
• Define the protection elements that will be enabled. Prepare a list of protection
functions including the following information. By default, all the protection
functions must be assumed “Disabled”:
