ADJUSTMENTS AND SETTINGS

15.22 Technical Reference Manual Chapter Issue 2 Jan 04

Mid Rail Setting 1. Using the setting plate, ensure that the mid rails are in line to the board/

snugger clamps (see position 1 on figure below).

2. Check that a nominal gap of 1mm exists between the end of the mid rail and

the board/snugger clamps.

3. Check using a 0.05mm feeler gauge for any gaps along the entire length of

the mid rail, adjust if the feeler enters any gaps.

4. Check that the mid rails are parallel to within 0.2mm.

NOTE

Mid rail width the same as or greater than the board clamp width.

Rail End Green

Insert Setting

1. Using the setting plate, ensure that the green inserts at each rail end are in

line to the mid rails (see position 2 on figure below).

2. Check that the green inserts are parallel to within 0.2mm.

NOTE

Green insert width the same as or greater than the mid rail width.

Width Check

1. In Diagnostics, select Rail System and Select Module.

2. Select Home Rail Width and Run Diagnost.

3. Select Adjust and set board width to 250mm (Carrier Handling Option -

300mm).

4. Select Drive Rail to Board Width.

5. Select Run Diagnost.

6. Check that the board clamp width is between 250.35mm - 250.55mm

(Carrier Handling Option - 300.35mm - 300.45mm).

7. Check that the mid rail width is between 250.35mm - 250.65mm (Carrier

Handling Option - 300.35mm - 300.55mm).

8. Check that the rail end green insert width is between 250.35mm - 250.85mm

(Carrier Handling Option - 300.35mm - 300.55mm).

NOTE

If any of the rail widths are out of tolerance do not adjust the rails, adjust the

position of the rail home position sensor and recheck.

9. Using a suitable test board, with the rail width programmed to the board size,

select Cycle Board on Belts.

10.Select Run and ensure the board runs through the entire length of the rail

system for 10 complete cycles, without jamming or excessive clicking of the

board edges.

NOTE

If any jamming occurs investigate the position of the board/snugger clamps, mid

rails and the green inserts at the rail ends before repeating the check.

Rail Shock

Absorber Setting

1. Ensure the machine is powered down.

2. Using feeler gauges, check that a gap of 2.5mm - 3mm exists between the

top of the plunger and the shock absorber body. Alternatively use a 2.5mm

and 3mm allen key as a Go, No Go Gauge.

3. Repeat Step 2 for the three other rail shock absorbers.

4. If adjustment is necessary, slacken the lock nut.

5. Rotate the shock absorber body as required, clockwise to reduce the gap,

anti-clockwise to increase the gap.

6. Check the gap is between 2.5mm - 3mm.

7. Repeat Steps 5 and 6 until the correct dimension is achieved

8. Tighten the lock nut.

9. Recheck the gap is still within limits.

CALIBRATIONS

15.24 Technical Reference Manual Chapter Issue 2 Jan 04

CALIBRATIONS

Board Transport

Belt Speed

The front and rear board transport belts (feeder belts) are driven independently

by two variable speed motors. Inevitably one motor drives faster than the other

motor. It is necessary to calibrate these motors so that they drive at the same

speed in either direction. Non-compliance of this calibration could cause boards

to jam in the machine or uneven wear in the rails or transport belts.

WARNING

LETHAL VOLTAGE. DANGEROUS VOLTAGES EXIST IN THIS

EQUIPMENT. ENSURE ALL ELECTRONIC COVERS AND MAIN

MACHINE COVERS ARE FITTED BEFORE OPERATING THIS

EQUIPMENT.

The speed of both feeder belt motors is controlled by a MultiMove card situated

in the machine control enclosure and utilizes Pulse Width Modulation (PWM).

This is achieved by controlling the period of the 'ON' control pulse provided by

the MultiMove control card. The pulse repetition rate is fixed at 125Hz.

Feeder motor speed is measured using a tachometer on the input or output pulley

and adjusted by using the Belt Speed Calibration Page in the machine diagnos-

tics.

NOTE

For belt speed calibration set up see Calibration Procedure of this section. For

detailed information on access and use of the diagnostics module refer to the

Diagnostics chapter of the User manual.

Motor speed software parameters is listed in the following table:
