Cummins 4914091 EFC
Update Time: 2010-4-14   Source:   Hits: 123

4914090,4914091 slow start controller used for the PT (G)-type fuel systems
for Cummins N, K series diesel generating sets.
4914090 used for less than 350KW units,and 4914091 used for less than 800KW
units.


Advantage

A, adapted from the launch controller starter group, reduce smoke, conducive
to boot.

B, strong resistance to external interference, reducing the interference of
the external controller to maintain stable operation of the units.

C, actuator shorted to protect and prolong life.


Appearance

Module housing is aluminum part,sizes: 150mm X 105mm X 40mm , the surface is
spray treated, Epoxy potting.


Main technical parameters

1, the working environment

Ambient temperature: -15 ~ +85 ℃

Relative Humidity: 0 ~ 95%

Vibration: 25 HZ 2 mm

2, power

Operating voltage: 24 ± 6 V DC

Grounding: Negative ground (body)

The maximum current: 2.5A, 24V

Dielectric Strength 100V: ≥ 500M


Wiring Methods

1 foot: battery positive,
2 feet: Battery negative

3,4 feet: connect the actuator (unsigned)

5 feet: connect Speed Signal positive,
6 foot: connect Speed Signal negative

7 feet, 9 feet: connect both ends of the outing transferr,
8 feet: connect the center of outing transfer

7 feet, 10 feet: then run switch off idle operation, closing idle

11 feet: Negative (optional connection)

A, B empty (set to debug, unstable when shorted)


Use setting

Idling Potentiometer (IDLE SPD): Idle 600-800 r / min, smooth rotation for
the acceleration, anti-spin for the spin-down.

Run potentiometer (RUN SPD): Run for the 1515 general load / min (50.5Hz),
rated load 1,500 rpm / min (50.0Hz).

Gain potentiometer (GAIN): smooth rotation fast response, good stability
against rotation. Georgia Department generally 5-7.

Transfer rate potentiometer (DROOP): anti-spin is small (hard), smooth
rotation is large (soft). These small machines can be harder, large machines
should be softer. Georgia, generally posited at 0-1.5.

Delay switch: the orders are 5,10,15 seconds, third gear switches are placed
in “OF” no delay; when using the delay-start, set to the running state,
switch to “ON”, can use any of the files individually, or two files, third
gear stacked.

Such as: 1 Slide “ON” position for 5 seconds for the delay, 1,2,3 income
into the ON position for the delay 30 seconds.

NOTE: Use a self-start controller, the proposed selection are 10-20 seconds.
