General Information Introduction This manual describes the Woodward 723PLUS Digital Industrial Speed/ Performance Control ‘598’, model 8280-598 (low voltage). Declaration of Incorporation In accordance with the EMC Directive 89/336/EEC and its amendments, this controlling device, manufactured by the Woodward Governor Company, is applied solely as a component to be incorporated into an engine prime mover system.

  • Page 10: Control Options

    D connectors. Control Options Each 723PLUS control requires 40 W of power. A nominal current in-rush of 7 A is possible. Acceptable input voltage range is 18 to 40 Vdc. Discrete input voltages provide on/off command signals to the electronic control, such as Raise Speed, Lower Speed, etc.
  • Page 11 The two communication ports (J2 and J3) and the LON # 1 data channel allow for digital communications between external Modbus compatible devices and Woodward LinkNet I/O modules. Up to 9 LinkNet modules have been designated for use and can be connected to the LON # 1 channel. The inputs and outputs of these modules can be read and controlled with Modbus compatible devices connected to communication ports J2 and J3.

    Power Requirements The low voltage version of the 723PLUS Digital Speed/Performance Control ‘598’ requires a voltage source of 18 to 40 Vdc. To prevent damage to the control, do not exceed the input voltage range.

  • Page 19: Internal Jumpers

    723PLUS Performance Control ‘598’ Internal Jumpers The 723PLUS control has ten, two-position internal jumpers (JPR1 through JPR20) located on the top of the printed circuit board. If you need to change any jumper to match your control needs, be sure to read Electrostatic Discharge Awareness (p.iv), before proceeding.

    723PLUS Performance Control ‘598’ Manual 26043 Figure 2-1. 723PLUS Control Internal Jumpers Where shielded cable is required, cut the cable to the desired length and prepare the cable as instructed below. Strip outer insulation from BOTH ENDS, exposing the braided or spiral wrapped shield.
  • Page 21 Power supply output must be low impedance (for example, directly from batteries). DO NOT power the control from high-voltage sources with resistors and zener diodes in series with the control power input. The 723PLUS control contains a switching power supply which requires a current surge (7 A) to start properly.
  • Page 22 To prevent possible damage to the control or poor control performance resulting from ground loop problems, we recommend using current-loop isolators if the 723PLUS control's analog inputs and outputs must both be used with non-isolated devices. A number of manufacturers offer 20 mA loop isolators.
  • Page 23 Manual 26043 723PLUS Performance Control ‘598’ Analog Output #1 (Terminals 15/16) Analog output #1 can be configured several different ways depending on the application needs. The output current is hardware configurable for either 0 to 1 mA or 4 to 20 mA. This current signal is supplied to terminals 15(+) and 16(–).
  • Page 24 LON #2 is not used. DO NOT CONNECT. Discrete Inputs (Terminals 29—36) Discrete inputs are the switch input commands to the 723PLUS control. They interact in such a way as to allow engine control under a variety of conditions. Voltage is supplied to the discrete input terminal when an input switch or relay contact closes.
  • Page 25 Manual 26043 723PLUS Performance Control ‘598’ In systems which provide an external low voltage source to power the 723PLUS control (or other systems where external low voltage dc power is available), the discrete inputs may be powered by this external low voltage. The voltage source used must be capable of supplying 100 mA at a voltage level of 18 to 40 Vdc.
  • Page 26 723PLUS Performance Control ‘598’ Manual 26043 Raise Air Manifold Pressure (Input C; Terminal 31) The input switch or relay contact used to activate the Raise Air Manifold Pressure function connects to terminal 31 (Discrete Input C). This discrete input changes the control operation by increasing the air manifold pressure reference ramp.
  • Page 27 Manual 26043 723PLUS Performance Control ‘598’ Lower Speed Contact (Input F; Terminal 34) The input switch or relay contact used to activate the Lower Speed command connects to terminal 34 (Discrete Input F). This discrete input changes the control operation by decreasing the speed reference ramp. The ramp can decrease only to a software adjusted LOWER SPEED limit.
  • Page 28 723PLUS Performance Control ‘598’ Manual 26043 Air Manifold Pressure Input (Signal Input #1; Terminals 42/43) Connect an air manifold pressure transmitter to Signal Input #1. The input signal must be an isolated high-quality signal. By configuration, this input is used in the air/fuel ratio, ignition timing, and turbocharger air assist controls, and for speed control fuel limiting.
  • Page 29 Communication Ports J2 and J3 Communication Ports J2 and J3 are used to connect two separate Modbus devices to the 723Plus control. These devices are used to read control parameters as well as read inputs from connected LinkNet nodes. The Modbus device connected to J3 can additionally drive LinkNet nodes and also drive certain 723Plus control parameters.
  • Page 30 Modbus Analog Write Address 0005 allows control of the speed reference. The signed 16-bit integer must be scaled as RPM for communication (that is, to produce a 330 RPM output from the 723Plus a value of 330 must be applied to address 4:0005).

    Manual 26043 723PLUS Performance Control ‘598’ Speed Control Dynamics The control algorithms used in the 723PLUS Industrial Speed/Performance Control ‘598’ are designed specifically for reciprocating engine applications. The control offers an effective set of dynamics for variable speed, variable load operation.

  • Page 102: Maximum Fuel Function

    723PLUS Performance Control ‘598’ Manual 26043 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 103: Fuel Limiting Function

    Manual 26043 723PLUS Performance Control ‘598’ Fuel Limiting Function Two separate Fuel Limiting Functions (AMP LIMIT curve and TORQUE LIMIT curve) provide limits to the fuel demand which prevents overfuel conditions. One function is based on an air manifold pressure transmitter signal provided at Signal Input #1.

    Reset command. An Alarm Reset can be issued by Modbus Boolean Write (BW) address 0:0001. An Alarm Reset is also issued when power is applied to the 723PLUS. And finally, the control issues an Alarm Reset during start-up (when configured).
  • Page 105 Manual 26043 723PLUS Performance Control ‘598’ The idle speed set point is provided for engine start-up or cool down speed. Idle speed may be set equal to or less than the rated speed set point. Idle is independent of the lower limit set point and may be set to a lower speed. Idle speed cannot be changed except through adjustment of the idle speed set point.

  • Page 106: Air/Fuel Ratio Reference

    Air/Fuel Ratio Reference The 723PLUS control provides an Air/Fuel Ratio control reference, based on fuel gas header pressure, engine speed, and air manifold temperature inputs, and discrete inputs for temporarily raising and lowering the air manifold pressure reference.
  • Page 107 (or 20 to 4 mA when Reverse Acting is selected). The actuator normally controls a turbocharger exhaust bypass valve, an intake air throttle valve, or an air dump valve to regulate air manifold pressure. The 723PLUS A/F Ratio control is compatible with these valve types, with appropriate actuators, for all the configurations provided.

  • Page 108: Ignition Timing Reference

    Configuring an air manifold pressure input failed alarm or shutdown is recommended. Ignition Timing Reference The 723PLUS control provides three tunable ignition timing reference curves and one configurable starting ignition timing setting. Settings are also provided to limit maximum advance and maximum retard. A low signal selector determines which ignition timing signal is applied to the ignition timing output.
  • Page 109 Manual 26043 723PLUS Performance Control ‘598’ This 2D curve has five breakpoints for setting the ignition timing versus air manifold pressure. The ignition timing reference is linear between breakpoints. Normal Ignition Timing A three-dimensional curve sets the Normal Ignition Timing reference as a function of speed and load.
