PRODUCT DESCRIPTION

Electromagnetic Interference (EMI) can be an intermittent condition. Improperly shielded installations can provide good control for a while and then cause problems. For this reason it is important to be sure all shields are properly installed.

Benefits:

With the prime mover operating at rated speed and no load, record the voltage 

across the actuator terminals 9 (+) and 10 (–). Shut down the prime mover and 

activate the Failed Speed Signal Override by closing the override contact. The 

voltage to the actuator should now be adjustable by the START FUEL LIMIT 

potentiometer. Set the actuator voltage about 30% higher than the voltage 

obtained at rated speed for forward-acting controls and 30% lower than rated 

speed voltage for reverse-acting controls. Remove the Failed Speed Signal 

Override contact if not required to start the prime mover. 

Start the prime mover and observe the start time, overshoot of speed setting, and 

exhaust smoke obtained. If the prime mover does not start, turn the START 

FUEL LIMIT potentiometer slightly clockwise until the prime mover starts. The 

START FUEL LIMIT may be adjusted as required to optimize the prime-mover 

starting characteristics. The fuel-limiting function is turned off automatically when 

the speed control takes over. 

For prime movers not requiring start-fuel limiting, the START FUEL 

LIMIT function can be deactivated by turning the potentiometer fully 

clockwise (be careful not to overtorque the pot). 

Speed Sensor Check 

If the sensor is a magnetic pickup, measure the voltage across terminals 7 and 8 

to be sure there is a minimum of 1.0 volts at cranking speed, and a maximum of 

30 Vrms at rated speed. If the voltage exceeds 30 volts, increase the gap of the 

speed sensor, and be sure that there is still a minimum of 1.0 volts at cranking 

speed. 

Droop Adjustment 

The amount of droop is not critical in many installations. If the engine needs to 

run in droop but the amount is not critical set the droop potentiometer in midposition, then adjust load with the speed-setting potentiometer. 

When paralleled with an infinite bus, the generator frequency cannot change, and 

unless a load- sensing module is being used, the control must be in droop to 

maintain stable operation. With the droop potentiometer at mid-position, parallel 

the generator, then increase the Rated Speed potentiometer until the desired 

amount of load on the engine is achieved. 

Too much droop will cause the engine to overspeed should the load be suddenly 

lost. Excessive droop will also cause the engine to be sluggish in response to 

load changes.
