3.7 Setpoint Programming

NOTE: To change a level 3 parameter requires either a level 3 password from the DSN or a PC connection using a service tool. Therefore, if you have a service tool, try to change the parameter using the service tool rather than calling the DSN.

Selecting “CHANGE LVL 1 PSWD” will allow for the level 1 password to be changed. The control must be at level 1 security in order to select “CHANGE LVL 1 PSWD”. The “CHANGE LVL 1 PSWD” screen looks just like the password entry screen. It has 16 blank spaces that can each be set to a number from 0 to 9. The password can use as few as one digit and can use as many as 16 digits. It is entirely up to the user. If a password has been set, but it is now desired to not have level 1 password protection, the level 1 password can be disabled by setting the password to be a single 0. Once the desired password is entered, press the enter key and the control will go back to the security screen and the level 1 password will be set.

Selecting “CHANGE LVL 2 PSWD” will allow for the level 2 password to be changed. The control must be at level 2 security in order to select “CHANGE LVL 2 PSWD”. The “CHANGE LVL 2 PSWD” screen looks just like the password entry screen. It has 16 blank spaces that can each be set to a number from 0 to 9. The password can use as few as one digit and can use as many as 16 digits. It is entirely up to the user. If a password has been set, but it is now desired to not have level 2 password protection, the level 2 password can be disabled by setting the password to be a single 0. Once the desired password is entered, press the enter key and the control will go back to the security screen and the level 2 password will be set.

NOTE: If a level 1 password is user defined, but a level 2 password has not been user defined, the control will go to level 2 security when a level 1 password is entered.

Selecting “CHANGE SCADA PSWD” will allow for the SCADA password to be changed. This password, if enabled, will require a SCADA system to first enter the password into the “Write Access Password” register prior to conducting any other reads and writes. The control must be at level 2 security in order to select “CHANGE SCADA PSWD”. The “CHANGE SCADA PSWD” screen looks just like the password entry screen. It has 8 blank spaces that can each be set to a number from 0 to 9. The password can use as few as one digit and can use as many as 8 digits. Just as with level 1 and level 2 passwords, entering a single 0 will disable the SCADA password. For more information about the SCADA password, please see “Data Link Security” under section 3.14.

The EMCP 3.1, 3.2, and 3.3 have a variety of setpoints (over 500 setpoints on EMCP 3.3) that can be programmed or adjusted. The setpoints can be adjusted via the built-in display or over the SCADA data link (not available on EMCP 3.1). For more information about programming setpoints over the SCADA data link, please see “EMCP 3 Setpoints” under section 3.14. In order to program the setpoints via the display, go through the following menu options. Main Menu ↵ Configure ↵ Setpoints ↵

In the setpoints menu there are seven submenus to choose from: • CONTROL • ENG MONITOR/PROTECT • EVENTS • GEN MONITOR/PROTECT • I/O • NETWORK • OTHER

Each of those submenus has additional submenus. Those additional submenus contain the setpoints.

CONTROL • AUTOMATIC START/STOP • AVR DESIRED VOLTAGE • GOV DESIRED ENG SPEED • SHUTDOWN OVERRIDE

ENG MONITOR/PROTECT • BATTERY VOLT MONITOR • CRANK/START COUNTERS • ENG COOLANT TEMP MON • ENG OIL PRES MONITOR • ENG SPEED MONITOR • ENHANCE ENG MONITOR • SERV MAINT INTERVAL

EVENTS • EVENT I/P FUNCTIONS • EVENT O/P FUNCTIONS • EVENT RESPONSE CONFIG o DIAGNOSTICS CONFIG o ENG PROTECT CONFIG o GEN PROTECT CONFIG o OTHER EVENTS CONFIG • EVENT SYSTEM

GEN MONITOR/PROTECT • ENHANCED GEN MONITOR • GEN AC MONITOR • GEN AC POWER MONITOR • GEN OVERCURRENT • GEN OVER/UNDER FREQ • GEN OVER/UNDER VOLT • GEN REVERSE POWER

I/O

• DIGITAL INPUTS • DIGITAL OUTPUTS • RELAY OUTPUTS • SPARE ANALOG INPUT

NETWORK • DATA LINK – SCADA

OTHER • DIGITAL SELECTORS • REDUCED POWER MODE

The setpoints can be three different types; numerical entry, menu, or in the case of the event response configurations there are options with checkboxes next to them.

Numerical entry setpoints are parameters like time delays, thresholds, etc. For these setpoints the display will show the current value. If that value is to be changed, first the control must be in the proper level of security. See “Security” for more information about the level of security. Then to change the value of the setpoint, press the enter key. The current value of the setpoint will be shown with the rightmost digit highlighted. Use the up and down arrow keys to adjust that digit to the desired value. Once that digit is set to the desired value, use the left arrow key to move the cursor to the next digit. Then use the up and down arrow keys to adjust that digit to the desired value. Continue this process until the desired value for the setpoint is set. Then press the enter key to save the value.

Menu type setpoints, such as generator configuration, have options that are not numerical. For these setpoints the display will show the current setting. If that setpoint is to be changed, first the control must be in the proper level of security. See “Security” for more information about the level of security. Then to change the value of the setpoint, press the enter key. The current setting will be highlighted. Use the up and down arrows to scroll through the options that are available for that setpoint. When the desired option is displayed, press the enter key to save the setting.

The setpoints for the event response configuration are a little different from the previously discussed setpoints. Selecting “EVENT RESPONSE CONFIG” will display four more submenus. Those four submenus contain all of the possible events that can be generated by the EMCP 3. Two of the submenus, “DIAGNOSTICS CONFIG”, and “ENG PROTECT CONFIG”, each have four more submenus.

• DIAGNOSTICS CONFIG o PRESSURES o TEMPERATURES o LEVELS o OTHERS • ENG PROTECT CONFIG o PRESSURES o TEMPERATURES o LEVELS o OTHERS • GEN PROTECT CONFIG • OTHER EVENTS CONFIG

Inside the submenus are the events. Use the up and down arrows to scroll through the events. For each event the display will have “VIEW” and “EDIT” at the bottom of the display. “VIEW” will be highlighted at first. In order to view the response configuration for that event, press the enter key. All of the possible event response options will be shown. There will be check boxes to the left of the options. The boxes with checkmarks in them are the options that are selected.

In order to edit the configurations, press the escape key once if the event is being viewed. Then use the right arrow key in order to select “EDIT”. The edit screen looks just like the view screen, but the highlighted option can be checked or unchecked by using the right arrow or left arrow keys. If the response configuration is changed, press enter to save the settings. NOTE: The control must be in STOP in order to edit any of the event response configurations. This applies to SCADA also.
