WOODWARD 701A Digital Speed Control

WOODWARD 701A Digital Speed Control

INTRODUCTION

The Woodward 701A Digital Speed Control offers improved speed control with models designed specifically for low-speed to highspeed diesel, gas, or pilot-fuel engines (one actuator moving two sets of linkages to the gas fuel valve and the diesel injection system).The 701A control uses a 16-bit microprocessor for all control functions. The control has enhanced control dynamics that give smooth steady-state operation, yet the control retains fast response to engine speed and load changes.

SPECIFICATIONS

ENVIRONMENT 

Operating Temperature：–40 to +70 °C (–40 to +158 °F)

Storage Temperature：–40 to +100 °C (–40 to +212 °F)

EMI/RFI Susceptibility and Emissions：EN50082-2, EN50081-2

ADJUSTMENT

All adjustments are done with the Woodward 9907-205 Hand Held Programmer with an RS422 serial port. This new lower-cost hand held terminal displays two parameters simultaneously and continuously updates them for easier monitoring. After all set points are adjusted to the desired value, the control saves them permanently in nonvolatile memory, which does not require batteries or other power sources to retain data. Entries can be changed at any time using the Hand Held Programmer.

The control has nine convenient “menus” for operation and adjustment: Menus 1 & 2 (Dynamics & Aux Dynamics) Gain, Stability, Compensation, Gain Ratio, Window Width, Gain Slope Breakpoint, Gain Slope Menu 3 (Speed Setting) Raise Speed Limit, Lower Speed Limit, Idle Speed Reference, Accel Ramp Time, Decel Ramp Time, Raise Speed Rate, Lower Speed Rate, 20 mA Remote Reference, 4 mA Remote Reference, Tach at 20 mA Output, Tach at 4 mA Output, Droop, Low Idle Breakpoint, Low Idle Droop, Torsional Filter.

Main Features

High-precision control: WOODWARD 701A adopts advanced algorithms and high-speed processors, which can realise precise control of the engine speed and improve the operating efficiency and stability of the equipment.

Easy to adjust: The governor provides an intuitive operating interface and a wealth of adjustment parameters, users can be set flexibly according to actual needs to meet the operating requirements of different working conditions.

High reliability: WOODWARD governor adopts high-quality materials and advanced manufacturing process, which has good durability and anti-interference ability, and can operate stably in the harsh working environment.

A variety of protection functions: the governor also has a variety of protection functions, such as over-speed protection, under-speed protection, etc., which can effectively prevent the equipment from being damaged due to malfunction and ensure the safe operation of the equipment.
