    ESD bag, at least until it is grounded. Power Requirements The 2301E control requires a voltage source of 18 to 36 Vdc, with a current capacity of at least 600 mA for operating power. If a battery is used for operating power, an alternator or other battery charging device is necessary to maintain a stable supply voltage.

  • Page 20: Location Considerations

    For example, relay contact wiring and electric motor drive or ignition system wiring should be at least 30 cm (12 inches) from any 2301E wiring. And for example, analog inputs/output wiring should be separated from power wiring by at least 15 cm (6 inches).

  • Page 21: Shields And Grounding

    (exception, see note below on cabinet installations). Shields can be grounded at both ends (2301E and load) if the cable length is sufficiently short (i.e., within a cabinet, less than about 10 m straight line between the ground points) to prevent ground loop current in the shield.

  • Page 22: Setting Speed Range

    Real Power Load Calculation The 2301E does not used the Real Power Equation. Instead the control uses the equation Power = 3 * I * COS Theta, I = current, and COS Theta = Power Factor or the phase difference between the voltage and the current.

  • Page 23: Power Supply (Terminals 48-50)

    Use shielded cable and connect the load-sharing lines directly to terminals 10(+) and 11(–). Connect the shield to terminal 12(chassis). When all controls in the system are of the 2301E, 2301D or 2301A types, the shields may be connected continuously between controls. When load sharing with different controls, do not connect the shields at the point where connections are made to the load-sharing- line bus or if needed, connect only through a capacitor.

When the contact is open, the control operates normally, turning the control output off in the event of a loss of speed signal.

  • Page 27: Idle / Rated Speed

    Manual 26641 2301E Digital Control Idle / Rated Speed The external contact used to activate the Rated Speed command connects to terminal 36 (default). This discrete input changes the control operation by increasing the speed reference to RATED SPEED and decreasing the speed reference to IDLE SPEED.

  • Page 28: Derate Kw Load Reference

    The dual dynamics control function is enabled by the Service menu item ENABLE DYNAMICS 2 W/CB. The 2301E has a droop tracking feature which allows the control to constantly monitor the system load. If the unit is in isochronous mode, and the unit is switched to the droop mode, the unit will maintain the current load level and also maintain the current engine speed (rpm).

  • Page 29: Lower Speed/Load Contact (Terminal 39)

    Manual 26641 2301E Digital Control The input switch or relay contact used to activate the Raise Speed/Load command connects to terminal 38 (Discrete Input E). This discrete input changes the control operation by increasing the speed reference ramp when the CB Aux input is open, and by increasing the base load reference when in base load mode.

  • Page 30: Load Generator (Terminal 40)

    Contact discrete input must be “TRUE” for the Load Generator input to affect the control. Note: When using the 2301E in a single engine, emergency standby application, this input must be “True”. The logic function of this input can be modified to be normally open or normally closed.
  • Page 31 Manual 26641 2301E Digital Control The 2301E control is designed to receive either 4–20 mA, ±2.5 Vdc, or 1–5 Vdc, representing a minimum Remote Speed/Load setpoint to a maximum Remote Speed/Load setpoint.

  • Page 39: Chapter 3. Description Of Operation

    This chapter provides an overview of the features and operation of the 2301E Load Sharing and Speed Control. The 2301E Load Sharing and Speed Control uses a 32 bit microprocessor for all control functions. All control adjustments are made with an external computer that communicates with the control via the RS-232 serial port.

  • Page 40: Control Dynamics

    2301E Digital Control Manual 26641 Figure 3-1. Speed Control System The digital control compares the numeric output of the speed sensor to the numeric number of the speed reference at the summing junction. If the speed is lower or higher than the reference, a response calculated by the PID (Proportional-Integral-Derivative control) is sent to the actuator driver calling for an increase or decrease in actuator current.

  • Page 41: Minimum Fuel Function

    Manual 26641 2301E Digital Control Constant dynamics refers to dynamics parameters that will remain constant as entered and do not vary with engine speed. Dynamics may be configured to vary with load by using the 5-Gain mapped dynamics. Constant dynamics are useful for fuel systems and processes that tend to be equally stable throughout the prime movers speed and load range.

  • Page 42: Maximum Fuel Function

    2301E Digital Control Manual 26641 Maximum Fuel Function The Maximum Fuel Function is a software-adjustable maximum fuel limit on the fuel demand. It is used to set a maximum position of the actuator. This is generally used to prevent engine overloading or other situations where the maximum fuel delivered to the engine should be limited.

  • Page 47 Manual 26641 2301E Digital Control When in baseload operation, the baseload reference determines the load on the generator without regard to other units connected to the same load. When the generator is carrying less load than the base load reference, the load bias is positive and the closed loop path increases the fuel to the engine.

  • Page 48: Droop Function

    2301E Digital Control Manual 26641 If the load command discrete input contact is opened (unload) while the breaker (CB AUX) input contact is closed, the generator will soft unload from the present load level to the unload trip level. Once the generator load has reached the unload trip level or the reference has been there for 5 seconds (tunable), the Open Gen Breaker relay output will open for 1 second (tunable).

  • Page 49: Figure 3-4. Paralleling System

    Manual 26641 2301E Digital Control The 2301E has a droop tracking feature which allows the control to constantly monitor the system load. If the unit is in isochronous mode, and the unit is switched to the droop mode, the unit will maintain the current load level and also maintain the current engine speed (rpm).

  • Page 50: Figure 3-5. Droop Mode

    2301E Digital Control Manual 26641 The output of the load amplifier is adjusted by the load gain set point. By setting the load gain voltage on each unit to the same level at full load, proportional load sharing is achieved. Regardless of differences in generator set capacities in the system, each generator set is loaded to the same percentage of its capacity.

  • Page 51: Figure 3-6. Isochronous Mode

    Manual 26641 2301E Digital Control Droop can also be accomplished by using the actuator output current, or Fuel Demand to predict what the load is. This is called Actuator Position Droop. This feature is enabled in the “N** LOAD SETTINGS **” menu. An actuator output at no load fuel demand percentage, an actuator output at full load fuel demand and an actuator droop percentage number is required for proper droop operation.

  • Page 52: Droop/Isochronous Load Sharing On An Isolated Bus

    2301E Digital Control Manual 26641 Droop/Isochronous Load Sharing on an Isolated Bus Droop/isochronous load sharing combines the first two modes. All generator sets in the system except one are operated in the droop mode. The one unit not in droop is operated in the isochronous mode. It is known as the swing machine. In this mode, the droop machines will run at the frequency of the isochronous unit.

  • Page 53: Isochronous Load Sharing On An Isolated Bus

    Droop is dependent on load (this is the measured kW) or on the actuator position. As already mentioned, droop based on the measured load in kW by the PTs and CTs (terminals 1 to 9) of the 2301E is used. With actuator droop the speed reference is decreased when the actuator output increases.

  • Page 54: Figure 3-9. Load Pulse / Rejection

    2301E. These signals measure the actual kW Load coming into the control. The 2301E calculates the derivative (rate of change) of the load, or basically how fast the load is changing with respect to time. If full load is applied to a generator, there is a small amount of time where the generator sees the load, but the engine has not yet started to slow down.
  • Page 55 The Generator Breaker Open Pulse feature must utilize the PT and CT signals connected to the 2301E. These signals measure the actual kW Load coming into the control. When the Load is greater than a preset value and the generator breaker opens, the fuel demand will instantly go to zero fuel for an adjustable period of time.
