EC20100 -- GENERAL INFORMATION

APPLICATION:
The EC20100 was designed for material spreading equipment and applications requiring a dual output weatherproof control.

DESCRIPTION:
The EC20100 is a compact, durable, and easy to operate control, built with high quality long life components that are designed for use in harsh environments. The EC20100 is a perfect compliment to the Brand EFC, LEFC, and SEFC flow controls. Other flow controls meeting the appropriate specifications may be used as well.

Ramping Down, or Fall Time Clockwise rotation increases ramp time
0.1 - 12 Seconds
Ramping Up, or Rise Time Clockwise rotation increases ramp time
0.1 - 12 Seconds
Pass Output Clockwise rotation increases pass output
0 – 2 Amps
Blast Output Clockwise rotation increases blast output
0 – 2 Amps

ADJUSTMENT PROCEDURES:

Adjustments are made by turning a trim pot screw. The trimmers are 25 turn, end to end devices. The trimmers have a built in slip clutches so over rotations do not damage them. It may be necessary to turn the adjustment screw several turns to observe a change in output. Start by adjusting the min output, and then adjust the max output to the desired level. The best way to fine tune adjustments is to observe the function response or speed. It is important to make adjustments in the following order.

1. Minimum output: Start by setting the master Potentiometer or input signal to zero. Turn the trimmer clockwise until the function begins to move. Now turn the trimmer back counter clockwise, one full rotation past the point of any visible movement.

2. Maximum output: Start by setting the master Potentiometer to the 100 position on the dial. Turn the trim pot counter clockwise to decrease function speed. Turn the trim pot clockwise to increase function speed. Function maximum speed will be limited to the max flow capabilities of your hydraulic system. Do not rotate the trim pot past the point of an observable increase in function speed.

3. Ramp up: This feature changes how quickly the valve can open. Clockwise turns increase the amount of delay. Counterclockwise turns decrease the amount of delay.

4. Ramp down: This Feature changes how quickly the valve can close. Clockwise turns increase the amount of delay. Counterclockwise turns decrease the amount of delay. Use discretion when making this adjustment, this will affect how quickly your function stops.

5. Blast output: Push the Blast button to observe whether or not adjustment is necessary. Turn the trim pot counter clockwise to decrease function speed. Turn the trim pot clockwise to increase function speed. Blast output will be limited to the span set by the Min and Max trimmers. Do not rotate the trim pot past the point of desired function speed.
