    SECTION 3 • FUNCTIONAL DESCRIPTION INTRODUCTION This section describes how the DVR2000E functions and explains its operating features. To ease understanding, DVR2000E functions are illustrated in the block diagram of Figure 3-1. A detailed description of each function block is provided in the paragraphs under the heading of DVR2000E Function Blocks. DVR2000E operating features include four operating modes, four protective functions, startup provisions, reactive droop compensation, underfrequency compensation, and an auxiliary analog input.

  • Page 21: Generator Voltage

    Generator Voltage Generator voltage is monitored at terminals E1 (A-phase), E2 (B-phase), and E3 (C-phase). Nominal voltages of up to 600Vac may be sensed at these terminals. Voltage applied to these inputs is scaled and conditioned before being applied to the input of the ADC. The voltage signal from phase C and A (V ) of the generator is used by the ADC to calculate the rms value of generator voltage across phases C and A.

  • Page 22: Section 2 • Human-Machine Interface

    Raise Closing a contact across terminals 6U and 7 causes the active operating setpoint to increase. This function is active as long as the contact is closed. Lower Closing a contact across terminals 6D and 7 causes the active operating setpoint to decrease. This function is active as long as the contact is closed.

  • Page 23: Front Panel Switches

    Front Panel Switches Changes to settings can be made at the front panel using the three pushbutton switches. These push-buttons are labeled Select, Up, and Down. Section 2, Human-Machine Interface provides more in-formation about the front panel switches. Relay Output A common alarm output contact is provided through terminals AL1 and AL2.

    PU V/Hz curve, the Underfrequency Active indicator flashes on the front panel and in MARATHON-DVR2000E-32. The knee frequency is adjustable from 40 to 65 hertz and the PU V/Hz curve may be set to a slope from 1 to 3 in increments of 0.01 through the Windows® or Palm OS® communication software.

  • Page 25: Overexcitation Shutdown (Field Voltage)

    Overexcitation Shutdown (Field Voltage) This function is enabled or disabled through MARATHON-DVR2000E-32 software. When enabled, if field voltage exceeds the setpoint (80 Vdc default), the Overexcitation Shutdown indicator flashes on the front panel and in the Windows® or Palm OS® communication software, the relay output closes after 15 seconds and the DVR2000E shuts down.

  • Page 26: Crowbar Shutdown

    Crowbar Shutdown The Crowbar Shutdown Circuit protects the generator rotor from overcurrent damage resulting from a shorted DVR2000E power switch. During operation, if the field voltage exceeds the setpoint and the power stage receives no gating pulses for 1.5 seconds, the Crowbar Circuit activates and places a short-circuit across the DVR2000E input power terminals.

  • Page 31: Connections

    CONNECTIONS DVR2000E connections are dependent on the application. Incorrect wiring may damage the unit. NOTE Be sure that the DVR2000E is hard-wired to earth ground with no smaller than 12 AWG copper wire attached to the ground terminal on the rear of the unit case. When the unit is configured in a system with other devices, it is recommended to use a separate lead to the ground bus from each device.

  • Page 32: Generator Voltage Sensing Inputs

    Generator Voltage Sensing Inputs The generator voltage sensing terminals are labeled E1, E2, and E3. A single-phase sensing connection is obtained by connecting the C-phase sensing input to terminals E2 and E3. Table 4-2 lists the terminal assignments for three-phase and single-phase generator voltage sensing. Table 4-1.

  • Page 44: Establishing Communication

    Establishing Communication Communication between MARATHON-DVR2000E-32 and the DVR2000E must be established before viewing metering values or reading or changing settings. MARATHON-DVR2000E-32 screen settings are updated only after communication is opened or the communication settings have been changed. Open the DVR2000E communication port by clicking on Communications on the menu bar, hovering the mouse pointer over Open Comm Port, and clicking RS-232 Port.

  • Page 45: Changing Settings

    Figure 5-6. Communication Initialization Screen NOTE MARATHON-DVR2000E-32 may display the dialog box of Figure 5-7 when initializing DVR2000E communication, obtaining DVR2000E configuration settings or performing other tasks. It’s important to wait until the box disappears before trying to execute communication commands. Issuing commands while the Wait dialog box is present may disrupt communication between MARATHON-DVR2000E-32 and the DVR2000E.

  • Page 46: Sending And Receiving Settings

    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 MARATHON-DVR2000E- 32 or closing communication.

    Figure 5-21. Protection Settings Screen Remove OEL - Current Level (A). The value of current in this field determines the excitation level that will cause the DVR2000E to issue an overexcitation limit alarm. A current level of 0 to 7.5 A may be entered in 0.001 increments. When the level of field current increases above the value of this field, the OVEREXCITATION SHUTDOWN LED on the front panel lights and the OEL time delay starts timing down.

Metering, Operation and Alarms - Operation Tab Gen Voltage (V). These metering values report the status of the V , and V generator voltages and are the products of the voltage sensed at terminals E1, E2, and E3 and the Generator PT ratio.

For example, a Regulator Sensing Voltage setting of 100 volts and a Band setting of 10 percent allows the Fine Adjustment function to increase the voltage setpoint to a maximum of 110 volts and decrease the voltage setpoint to a minimum of 90 volts. For VAR, PF or FCR modes, the Raise and Lower buttons allow fine adjustment over the entire adjustment range.

  • Page 62: Pid Data

    MARATHON-DVR2000E-32 automatically calculates PID values after the user selects the generator frequency, generator time constant (T’do), and exciter time constant (Texc). With MARATHON-DVR2000E-32, the user may generate new PID numbers, add to a PID list file, and update the AVR gain settings.

  • Page 63: Adding To The Pid List

    Saving DVR2000E settings to a file for uploading to other DVR2000E units saves setup time when configuring multiple units to the same configuration. A settings file can also be created in MARATHON-DVR2000E-32 without being connected to a DVR2000E. The settings of the desired screens can be changed and these settings can then be saved to a file.

  • Page 64: Uploading Settings Files

    DVR2000E settings files are automatically given a .de1 extension by MARATHON-DVR2000E-32. Uploading Settings Files A DVR2000E settings file downloaded from a DVR2000E or created within MARATHON-DVR2000E-32 can be uploaded to multiple DVR2000E units. Only a DVR2000E settings file with a .de1 extension can be uploaded to a DVR2000E unit.

  • Page 88: Section 7 • Maintenance And Trouble-Shooting

    The only preventive maintenance required on the DVR2000E is to periodically check that the connections between the DVR2000E and the system are clean and tight. DVR2000E units are manufactured using state-of-the-art, surface-mount technology. As such, Marathon Electric recommends that no repair procedures be attempted by anyone other than Marathon Electric personnel.

    If the turns ratio of the sensing potential transformer is incorrect, replace the sensing potential transformer with the correct one. If the sensing potential transformer is correct, proceed to Step 3. Step 3. High generator output voltage may occur when operating in droop mode with a capacitive load. If the high voltage condition is not caused by the droop function, proceed to Step 4.
