8. Reinstall the camera and bracket.

9. Reconnect the camera and light source cables.

10. Close the dispensing area door.

11. Recalibrate the camera, see 5.6 Calibrating the Scale.

12. Perform a machine offsets procedure.

Refer to the Fluidmove User Guide or Fluidmove

Online Help to perform the offset procedures.

To test counterbalance tension:

1. Place valve on Z-head and move the valve to middle of dispense area.

2. Open the dispensing area door.

 The Z-head should not rise or drop more the 6.3 mm (1/4 inch).

3. Readjust tension if necessary.

5.8 Adjusting the Board Sensors

Board sensors are optical sensors located along the length of the front conveyor rail. The sensors detect

the presence of the workpiece and report it to the conveyor controller. Board sensor sensitivity should be

adjusted after initial installation and if the sensors fail to sense the presence of a workpiece. Depending on

whether the system has a single-lane or dual-lane conveyers, there may be as many as six downward-

facing board sensors (pre-dispense, dispense, and post-dispense station for each conveyor). Sensitivity

adjustments for downward-facing board sensors are made on fiber optic amplifiers mounted under the

dispensing area front cover.

5.8.1 Standard Operation and Tuning

To install the board sensor (Figure 5-13):

1. Unlock the fiber lock (UP position). Insert ferrule ends until the fiber cords are fully seated.

Lock the fiber lock down into position on the conveyor rail.

 NOTE Fiber ends are not designated as send or receive. Each ferrule can be used in

either amplifier position.

2. Verify that the digital value of the amplifier is less than 100 with the fiber array pointed

away from any objects (within 6 inches). This ensures array “cross-talk” will not

significantly degrade the signal.

Figure 5-13 E3X-HD Board Sensor

To adjust for workpiece presence/absence (Figure 5-14):

 NOTE The E3X-HD 11 sensor requires only one button; place the part/board over the sensor and

push

STune and then move the part/board away from the sensor and push STune again.

1. With the dispensing system on and the fiber installed into the amplifier, place the

carrier/board on the conveyor so that it is breaking the fiber optic sensor beam.

2. Press the

STune button once.

3. Move the carrier/board so that it is clear of the fiber optic sensor beam.

4. Press the

STune button again.

5. Ensure the threshold level (number in red after inverting display, green if normal display) is

between the board present/not present range.

6. If the threshold number is in range, standard tuning is complete.

7. If the threshold value is not in the range of the present/not present values, follow the steps

below to adjust the light level. Step 7a through Step 7e are only required if the board sensor

does not respond correctly after adjustment.

a. Press and hold the

Mode button for 3 seconds until [Func dFLt] (or [Func oPt])

begins to blink on the display.

b. Click

Mode button once. You will see [HS] followed by a number.

c. Click the (

+) button until you see [Stnd]. Press and hold Mode until the two sets of

numbers appears again.

d. If the threshold number is still not within the range of values, repeat Step 7b and

Step 7c, but this time click the (

+) button until you see [GIGA].

e. If threshold is still not within range, the fiber optic sensor will need to be moved closer

to the carrier/board.

5.8.2 Inverting the Display

To invert the display (Figure 5-14):

1. Press and hold the

Mode button for 3 seconds until [Func dFLt] begins to blink on the

display.

2. Click the

Up (+) button once so that [Func oPt] appears.

3. Press the

Mode button until [rEv oFF] is shown.

4. Click the

Up (+) button once so that [rEv on] appears.

5. Press and hold the

Mode button for 3 seconds until the two sets of numbers appear.

 After inverting the display, the above diagram will be reversed; the green numbers will

represent the current light level and the red numbers will represent the threshold.
