PRODUCT DESCRIPTION

Be prepared to make an emergency shutdown when starting the engine, turbine, or other type of prime mover, to protect against runaway or overspeed with possible personal injury, loss of life, or property damage.

Benefits:

Preset rated speed. 

 If a signal generator is not used, set the RATED SPEED potentiometer at 

minimum (fully counterclockwise). 

 If a signal generator is used set the signal for the frequency of the speed 

sensor at rated speed, and connect it to terminals 7 and 8. (The rated speed 

frequency in Hz equals the rated engine speed in RPM times the number of 

teeth on the speed sensing gear, times the ratio of engine speed to speedsensing-gear speed, divided by 60.) Put the Close For Rated contact in 

rated (closed) position. Set the speed trim potentiometer (if used) to midposition. Connect a dc analog voltmeter to terminals 9 (+) and 10 (–) to read 

actuator voltage. 

 If the actuator voltage is at minimum (about 0 volts) slowly turn the RATED 

SPEED potentiometer clockwise (counterclockwise for reverse acting 

controls) until the voltage just begins to move toward maximum. 

 If the actuator voltage is at maximum, slowly turn the RATED SPEED 

potentiometer counterclockwise (clockwise for reverse-acting controls) until 

the voltage just begins to move toward minimum. 

 Continue to very slowly adjust the RATED SPEED potentiometer in the 

appropriate direction, trying to stop the actuator voltage between the 

minimum and maximum voltages. Because it is not possible to stop the 

motion, cease adjusting when the voltage changes very slowly. The RATED 

SPEED potentiometer is now set very close to the desired speed. A slight 

adjustment when the engine is running will achieve the exact speed.
