ADJUSTMENTS AND SETTINGS

Rail Lifted Sensors Both the left and right rail lifted sensors are through beam optos and mounted

either side of the rising table so to detect premature lifting of the rear rail, as

described in the Drives and Sensors section of this chapter.

The opto vane brackets are height adjustable and are set using a 0.5mm feeler

gauge, so that if either opto is moved by a minimum of 0.5mm above the vane

setting (whilst the table is in the home position), then the LED switches to OFF

indicating an error warning to the operator.

NOTE

Rail Lift Setting figure of this chapter also refers.

Figure 15-9 Rail Lifted Sensor Location

Rail Width Home

Sensor

The rail width home sensor is used to find the home position of the moving rail

and is described in detail in the Sequences section (Homing Sequence) of this

chapter.

The sensor is mounted on an adjustable bracket which enables the position

between the front and rear rails to be set at 508.5mm - 508.7mm, (measured

between the inside edges of both rails, when the moving rail is in the home

position).

A fine adjustment can be made to the set rail dimension by slackening the sensor

forward securing screw and turning the home sensor adjustment screw (Figure

Rail Home Setting refers) in accordance with the table on the next page.

Board at Left/Right

Optos

When fitted to the machine rails the diffuse sensors switching threshold can be

adjusted by means of a sensitivity control switch. This ensures that when a board

is fed into the machine (via the transport belts), the sensor output switches to ON.

To achieve an optimum setting carry out the following procedure:

1. Place a board on the rails covering the sensor.

2. Turn the sensitivity control fully anti-clockwise, ensure that the green LED

is extinguished.

3. Re-adjust the sensitivity control clockwise until the green LED illuminates.

4. Remove the board from the rails and confirm that the green LED extin-

guishes and the red LED illuminates.

5. Turn the board 90° and position back onto the rail system (so that the board

lies on top of the rail system as shown in the figure below). Confirm that the

red and green LED’s are extinguished. (If the green LED illuminates, turn

the sensitivity control anti-clockwise until the green LED extinguishes.)

6. Remove the board. Position the board back on the rail system, as in Step 1,

and confirm that the green LED illuminates. Carry out Step 4.
