An EFB (Electronic FeedBack) controller is used to control up to four independent servo

loops. Each of these loops consists of a servo valve, an actuator (hydraulic or pneumatic

cylinder), and a transducer (10 Kohm variable resistor) linked to the actuator.

In operation, a control voltage (nominally 0 to 10 VDC) is sent to the EFB controller. The

EFB circuitry compares this incoming voltage with the current position of the actuator as

sensed by the transducer. If the current position of the actuator and input voltage

disagree, then the EFB controller opens the valve so that the actuator moves towards the

target position until they do agree. If the difference between the command and the

actual position was small, then the servo valve is only opened a little. If the difference in

position is great, then the valve is opened all the way. Servo valves differ from typical

solenoid valves in that they can open just a little or a lot.

The most common failure in animated figures which use EFB analog movements are

broken wires leading to the transducer. For that reason Gilderfluke's EFB controller was

designed so that it only needs two wires to the transducer (three are usually required) and

it constantly checks the status of these wires. If there is a wire break, it will immediately

switch the gain setting to a secondary 'low gain' control, which you can adjust to keep the

movement from slamming one side. When a break is sensed, or when power is first

applied to the EFB controller, it will stay in the error condition for approximately 10 seconds.

This will keep circuits with loose wire connections from jumping in and out of error condition.

There is a 'broken wire' indicator LED for each of the four channels in the EFB controller. If

any of the circuits is in an error condition, then the 'error' LED will light. This error signal can

be remoted through a standard J-8 cable. The EFB controller provides an optically

isolated transistor output between the black wire (collector) and the white wire (emitter). The

White wire isn't normally used by the connections to the Standard Micro MACs bricks, so

that the same cable can be used to sum the error indicators and control signals from any

number of bricks and EFB controllers and route them to a central indicator panel. Smart

Brick Systems will need to use a separate cable, as these two conductors are used for

other purposes in the Smart Brick Network cables.

If any channels are left unused on the Quad EFB controller, you will need to short

together the transducer inputs on the unused channels to turn the ERROR LED off.
