SENDING AND RECEIVING SETTINGS
When communication is enabled, DECS-100 settings can be sent or received through BESTCOMS.
Sending Settings
Settings changes are sent to the DECS-100 by clicking the SendToDECS button. This causes the
selected setting displayed on the current settings screen to become the DECS-100 setting. Settings can
also be sent to the DECS-100 by clicking Communications on the menu bar and clicking Send To
DECS. Additionally, a setting can be sent by pressing the Enter key after the new value is typed in. The
SendToDECS button must be clicked or the Enter key must be pressed after each setting change to
ensure that all settings are sent to the DECS-100. After the settings transfer is complete, wait at least five
seconds before removing power. See Saving Settings to DECS-100 Memory for information about
retaining DECS-100 settings after operating power is removed.
Receiving Settings
DECS-100 settings are retrieved by clicking the GetFromDECS button. This causes the current settings
of the DECS-100 to be displayed on the settings screen. Settings can also be received from the DECS-
100 by clicking Communications on the menu bar and clicking Get From DECS.
Saving Settings to DECS-100 Memory
Settings are saved in nonvolatile memory (EEPROM). In the event of a power loss, these are the settings
that are active at power up. If settings are changed and sent to the DECS-100, but not sent to EEPROM,
the changed settings are lost if DECS-100 operating power is lost. When exiting BESTCOMS or closing
communication, you are asked if you want to save the settings to EEPROM. This question is asked even
if no settings changes were made.
When communication is enabled, setting changes are saved to EEPROM by clicking the EEPROM
button. The opportunity to save settings to EEPROM is also given through a dialog box when exiting
BESTCOMS or closing communication.
After settings have been saved to EEPROM, wait at least five seconds before removing power.
SETTING DEFINITIONS
Each of the six setting groups has a corresponding BESTCOMS screen. The settings of each screen are
categorized by one or more tabs. In the following paragraphs, settings are arranged and defined
according to the organization of the BESTCOMS screens and tabs.
System Configuration
The System Configuration screen consists of one tab labeled System Settings. Click the Configure
button to access the System Configuration screen or click Screens on the menu bar and click System
Configuration.
System Settings
System settings are shown in Figure 5-6 and described in the following paragraphs.
Sensing Voltage. This setting is used to configure the DECS-100 for either single-phase or three-phase
sensing voltage.
Limiter Mode. This setting enables and disables the excitation limiters. Overexcitation limiting (OEL) or
underexcitation limiting (UEL) can be enabled independently, both can be enabled, or neither limiter
enabled.
OEL Type. This setting configures the overexcitation limiter as a summing point limiter or takeover-style
limiter.
Generator Frequency. This setting is used to select a nominal system operating frequency of 50 hertz or
60 hertz.
Setpoint Auto Save. When enabled, this feature automatically saves setpoint changes in nonvolatile
memory. A change made to any setpoint (AVR, FCR, Var, or PF) initiates a 10 minute time delay. When
the time delay expires, the DECS-100 automatically saves the setpoint values in nonvolatile memory.
When disabled, this feature is not active and any setpoint changes must be saved to nonvolatile memory
by clicking the EEPROM button.
