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.
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 (VC-A) of the generator is used by the ADC to calculate the rms value of generator voltage across phases C and A.
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. Var/Power Factor Control (52J/K) Option Closing a contact across terminals 52J and 52K disables var/power factor control.
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. This normally open, form A contact annunciates alarm or generator trip conditions and closes in the event of a protective shutdown or transfer.
with an infinite bus. The DVR2000E(C) calculates generator power factor using the sensed generator output voltage and current quantities and then adjusts the dc excitation current to maintain power factor at the setpoint. Power factor control is enabled or disabled through the front panel switches, Windows® or Palm OS® software. When the software is turned on, it is enabled or disabled through the Var/Power Factor Control (52J/K) contact input circuit. The power factor setpoint is adjustable between 0.
• • • • • • Overexcitation shutdown Generator overvoltage shutdown DVR overtemperature shutdown Loss of generator sensing shutdown Overexcitation limiting Crowbar shutdown Each function, except Crowbar Shutdown, has a corresponding front panel indicator that lights when the function is active. An active function (except Crowbar Shutdown) is also annunciated through the Windows® or Palm OS® communication software.
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. This protects the generator by blowing the input power fuse and removing operating power from the device.

Figure 5-21. Protection Settings Screen Remove S5 ection 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. OEL - Alarm Time Delay (sec).
Operation Tab Operation tab metering values, setpoint values and control functions are illustrated in Figure 5-22. Figure 5-22. Metering, Operation and Alarms - Operation Tab Gen Voltage (V). These metering values report the status of the VA-B, VC-B, VC-A, and VAVG generator voltages and are the products of the voltage sensed at terminals E1, E2, and E3 and the Generator PT ratio. All metering values are updated once each second.
Reactive Power (var). This value is the calculated product of the metered generator voltage (VAVG), metered generator current (IB) square root of 3 and the sine of the metered phase angle. See Equation 5-3. Equation 5- 3. Reactive Power Equation Power Factor. This value is the calculated result of dividing the Real Power (W) value by the Apparent Power (VA) value. See Equation 5-4. Equation 5- 4. Power Factor Equation Operating Status.
the Regulator Sensing Voltage setting plus/minus the Band setting. 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.
PID DATA MARATHON-DVR2000E-32 enables generator stability to be set through the automatic calculation of PID parameters. PID stands for Proportional, Integral, Derivative. The word proportional means that the response of the DVR2000E output is proportional or relative to the amount of change that is observed. Integral means that the DVR2000E output is proportional to the amount of time that a change is observed. Integral action eliminates offset.
Adding to the PID List CAUTION Improper PID numbers will result in poor system performance or system damage. PID parameters can be added to a list and recalled for operation and comparison. To add to the list, type a name for the generator (or other appropriate information) in the generator information box. Select the generator time constant. Observe the PID gain parameters in the Field Output Data fields. If these gain parameters are appropriate, click the Add to PID List button.

SECTION 7 • MAINTENANCE AND TROUBLESHOOTING PREVENTATIVE MAINTENANCE 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 soft start settings are incorrect, adjust the settings. If the soft start settings have no effect, proceed to Step 8. Step 8. Replace the DVR2000E unit. If replacing the DVR2000E unit does not correct the malfunction, then the generator is defective. Consult with the generator manufacturer. Low Generator Output Voltage Step 1. Verify that the voltage adjustment is not set too low. If the voltage adjustment is too low, adjust it to the correct setpoint.
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. Step 4. Replace the DVR2000E unit. Poor Voltage Regulation Step 1.
If the Stability Level is not properly set, reset the Stability Level. OVEREXCITATION SHUTDOWN Indicator Is Annunciating Step 1. Verify that the field overvoltage setpoint is adjusted properly. If not properly adjusted, readjust the field overvoltage setpoint. If properly adjusted, proceed to Step 2. Step 2. Check for generator overloading. If the generator is operating with a larger than rated load, shed load. If the generator is operating with a rated or less than rated load, proceed to Step 3.
If the generator exciter field is not shorted, proceed to Step 4. Step 4. Replace the DVR2000E. If replacing the DVR2000E does not correct the malfunction, proceed to Step 5. Step 5. Refer to the generator manual. Generator is defective. UNDERFREQUENCY ACTIVE Indicator Is Annunciating Step 1. Verify that the generator is operating at rated speed. If the generator is not operating at rated speed, adjust the generator speed. If the generator is operating at the rated speed, proceed to Step 2. Step 2.
