Modification PCB Mounting

If you have purchased a complete controller this section may be passed over and you may proceed to

General Description.

1. Place the Main PCB in front of you with the long dimension in a horizontal position and the

terminal strip to the left.

2. Remove the DIP switch by pulling it straight out of the receptacle, RECP 1. Then, peel the adhesive-

backed label off the other half of RECP 1.

3. Insert the arrow-type locking head of the four nylon stand-offs supplied into the four 0.188"

diameter holes in the main PCB and press in. The tabs will snap out to lock the stand-offs

permanently in position.

4. Hold the modification PCB assembly over the stand-offs with the ribbon connector toward you

and insert the ribbon connector plug into RECP 1. Be careful to see that all 16 pins are started

properly into the receptacle before pressing the plug in.

5. Align the holes in the modification PCB assembly over the stand-offs and press over the tapered

posts until the locking flanges snap out to lock the board in position.

General Description

The Dancer Position modification converts the standard 4000 and 4050 controllers into a position control

system. The feedback quantity to the Main PCB becomes the position of a Dancer Operated

potentiometer rather than the drive output shaft velocity. The steady state position of the "dancer" is

actually controlled by adjusting the drive velocity so that a constant take-up reel, outer edge tangential

velocity, equal to the line speed, is maintained. The modification circuit includes a supplementary clutch

current bandpass filter circuit and a position rate circuit to provide the lead compensation necessary for

stability. The current gains are adjustable so that the dynamic response of a specific system can be tuned.

Visual Inspection

1. Before proceeding to the set-up procedure, check the controller for any damage that may have

occurred during shipment, such as loose connections and damaged wire or components.

2. Check all interconnection wires for conformance to connection diagram and schematic as

supplied in this instruction sheet.

3. Check the Operator's controls (which are supplied by customer) to see if they are connected

properly per the connection diagram. This includes the Dancer Position pot R5 and the Start and

Stop pushbutton controls.

Preliminary Adjustment

Perform the following preliminary adjustments (with no power applied to the controller)

A. Operator's Controls (supplied by customer unless specified)
