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.

Home Position Rail
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.
4. Select Drive Rail to Board Width.
5. Select Run Diagnost.
6. Check that the board clamp width is between 250.35mm - 250.55mm.
7. Check that the mid rail width is between 250.35mm - 250.65mm.
8. Check that the rail end green insert width is between 250.35mm -
250.85mm.

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 - 3.0mm exists between
the top of the plunger and the shock absorber body. Alternatively use a
2.5mm and 3.0mm 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 - 3.0mm.
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
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.
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
diagnostics.
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:
