Product Description
Original EFC CONTROLLER EFC4914090 speed controllerProduct Description

 Application Features 
A. Low smoke displacement, soft noise 
Meet the demand of environment protection imp rive people' S 
Feeling. 
B. Easily start in cold, plateau and Ww pressure areas, 
Especially for N-G-250kw and K-G-300kw sets. 
C. High ability to anti-disturbance Stable operation due to the large power walkie-talkie· 
D. Actuator can not be damaged in case of short circuit due to 
The output protector. 
E. Diesel with water pump cam start with wad, the range of round per minute cam be ± 600, that is 1000-1200 rpm. 
Principles 
The oil valve of the speed regulator is totally 
Open and if the supercharger low-speed and with little 
Air input, So it is difficult to ignite the fuel and cannot 
Completely ignite and have thick smoke displacement. It starry400-1200rpm, It need 3-5or 10-20 minute 
To accelerate. 
It can easily start if we decrease the oil input. After it start, then increase' The oil input, the speed and the diesel generator temperature will increase gradually. Thus, the smoke displacement is Ww and the noise is soft. 
The operation of and use of the set after start is same as other regulators. 
Operation methods
A. Apearance Feature: It is same as other regulators. 
B. Switchesc: Seitches for after start while all the 3 switches downside, it can ccelerate immediately, while switch them upside respectively. It can accelerate in 5' , 10' , 15respectively. 
As the picture described (7-10 cannot connect prompt switches). The time more needs the smoke thinner and much easier to start. 
C. The lasting time of the start switch vibration is a little wag... 
During acceleration, if there is displacement stroke and displace black smoke, please regulate GAIN. 
D. If the sets adopt self-start
