PRODUCT DESCRIPTION

To prevent damage to electronic components caused by improper handling, read and observe the precautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed Circuit Boards, and Modules.

Benefits:

The speed-signal voltage is compared to the reference voltage at the summing 

point. If the speed-signal voltage is lower or higher than the reference voltage, a 

signal is sent by the control amplifier calling for an increase or decrease in 

speed. The actuator is controlled by this signal, repositioning the fuel valve or 

rack until the speed-signal voltage and the reference voltage are equal. 

Auxiliary Inputs 

Terminals 11 through 17 are used for auxiliary inputs which change the reference 

voltage and thus the output of the speed control. These inputs include speed 

trim, droop, SPM synchronizer, and the auxiliary input, (usually from a load 

sensor and parallel lines). 

Failed Speed Signal Circuit 

A failed-speed-signal circuit monitors the speed-signal input. When no signal is 

detected, it calls for minimum fuel. The minimum-fuel signal is sufficient to cause 

the actuator to go to the minimum position. Incorrect linkage adjustments or other 

restrictions in the external system may prevent prime-mover shutdown. 

For controls with actuator current of 20 to 160 mA, minimum fuel is defined as: 

· Actuator current of less than 10 mA for forward-acting controls. 

· Actuator current greater than 180 mA for reverse-acting controls. 

For controls with actuator current of 40 to 320 mA, minimum fuel is defined as: 

· Actuator current of less than 20 mA for forward acting controls. 

· Actuator current of more than 360 mA for reverse-acting controls. 

A contact to override the failed-speed-signal circuit can be connected in series 

with terminal 4 and low voltage dc power. (This power is available on terminal 2 

for units supplied with 10 to 40 Vdc power and from terminal 6 on those units 

supplied with about 120 V ac or dc power.) Temporarily closing the contact 

overrides the failed-speed-signal circuit as required for start-up. 

The control must be tuned to each system for optimum performance. The 

potentiometers for setting and adjusting these circuits are located in the upper 

right corner of the control as shown in Figure 4-2. They include:
