PRODUCT DESCRIPTION

One side of the secondary of all CTs must be earthed. The earth connection should be made on the side of the secondary facing the protected object. The polarity of the CTs must be in accordance with the following diagram.

Benefits:

Check Failsafe and Actuator Travel: 

 Set the signal-generator frequency to about half of idle speed. Set the idlerated switch to rated. Turn the signal generator and governor power on. The 

linkage must be at the maximum-fuel position. Except for Detroit Diesel 

engines, verify that linkage travel is limited by the prime-mover fuel control, 

not by the actuator stop. Turn the signal generator off and remove the 

connections at terminals 5 and 6. The linkage should move to the minimum 

fuel position. Verify that linkage travel is limited by the prime mover’s fuel 

control, not by the actuator stop. 

 Preset Rated Speed: 

 Set the signal generator for MPU frequency at rated speed and connect it to 

terminals 5 and 6. Put the idle-rated switch in the rated position. Set the 

speed trim pot, if connected, to mid-position. Observe the linkage position. 

 If the linkage Is at the maximum fuel position: 

 Slowly turn the rated speed pot counterclockwise until the linkage just 

begins to move to the minimum fuel position. Start Fuel (if present) must be 

adjusted to the maximum clockwise position or the actuator will not move to 

maximum. 

 If the linkage Is at the minimum fuel position: 

 Slowly turn the rated speed pot clockwise until the linkage just begins to 

move to the maximum fuel position. 

 Continue to adjust the rated speed pot very slowly in the appropriate 

direction, trying to stop the linkage between the minimum and maximum fuel 

stops. Because it is not possible to stop the motion, cease adjusting when 

the linkage moves slowly. The rated speed reference is now set very close 

to desired speed. A slight adjustment when the engine is running will 

achieve the exact speed. 

 Preset Idle Speed: 

 Preset idle speed only after presetting rated speed. Set the signal generator 

for the MPU frequency at idle speed. Put the idle-rated switch in the idle 

position. Observe the linkage position. 

 If the linkage is at the maximum fuel position: 

 Slowly turn the idle speed pot counterclockwise until the linkage just begins 

to move to the minimum fuel position. Start Fuel (if present) must be 

adjusted to the maximum clockwise position or the actuator will not move to 

maximum. 

 If the linkage is at the minimum fuel position: 

 Slowly turn the idle speed pot clockwise until the linkage just begins to move 

to the maximum fuel position. 

 Continue to adjust the idle speed pot very slowly in the appropriate direction, 

trying to stop the linkage between the minimum and maximum fuel stops. 

Because it is not possible to stop the motion, cease adjusting when the 

linkage moves slowly. The idle speed reference is now set very close to 

desired speed. A slight adjustment when the engine is running will achieve 

the exact speed.
