1.3 Changing Setpoints
1.3.1 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 Phase Overcurrent 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 489 settings fall into one of following categories: device settings, system settings,
digital input settings, output relay settings, current element settings, voltage element
settings, power element settings, RTD temperature settings, thermal model settings,
monitoring settings, analog input/output settings, and testing settings.
Note 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).

CHAPTER 1: GETTING STARTED
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 489 Setup software incorporates a facility for programming the relay
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.
1.3.2 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.
1.3.3 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 489 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 VALUE Skey to increment the displayed value by the step
value, up to a maximum allowed value. Likewise, the VALUE Tkey decrements the
displayed value by the step value, down to a minimum value. For example:
ZSelect the S1 489 SETUP ZV PREFERENCES ZV DEFAULT MESSAGE
TIMEOUT setpoint message.
ZPress the 1, 2, and 0 keys. The display message will change as shown.
Until the ENTER key is pressed, editing changes are not registered by the relay.
Therefore,
ZPress the ENTER key to store the new value in memory.
The following message will momentarily appear as confirmation of the
storing process.
