20.4.3 Common Machine Problems

The following problems are given as some of the most common problems that can occur in the

day to day working with the machine. Each problem is first described and then potential solutions

are offered. These are designed to offer a useful start for machine trouble shooting.

Error Message: Recovery:

Nozzle gets dirty or worn Remove and clean the nozzle in the appropriate segment or

replace the nozzle if there are any left in the changer.

Difference between open and

closed vacuum values are too

small.

Wrong nozzle on the sleeve. Repeated occurrence at the

same segments infers the need to clean the valves.

Star doesn't turn because of

valve control.

Move valves of segment concerned and press the start button

for a reference run. Clean or exchange the valve in case of an

error with a single unit.

Unable to find the fiducial or

ink spot during position rec-

ognition

Press the start button and ALT+8 to switch the display to the

camera picture for diagnosis. Possible problems: conveyor set

too wide; bad fiducials or ink spot; search field too small; bad

or damaged circuit board.

Pick-up problems (track

empty errors).

Check feeders for correct pitch, proper seating (debris under

feeder or debris on magnetic track?). If feeder is feeding prop-

erly, make sure the tape cover is properly closed, check for

parts in the feeder drive, proper movement of tape cover and

tape reel, proper tape retraction, or the correct vacuum at the

star. Turn the maintenance key and operate in single function

mode for diagnosis.

Error with the height refer-

ence run.

Nozzle is missing. Wrong nozzle. Nozzle did not lock after a

nozzle change.

X,Y axes invalid command or

deenergized.

Try the start button 2 or 3 times. Under gantry functions - >

gantry reference run.

Communication with compo-

nent table disrupted

Options - > load component table program. Power machine off

then on again. Check component table data and power cables.

If problem occurs with certain component/feeder, exchange

the feeder.

Switch on compressed air Compressed air supply pressure too low. Do not leave the ma-

chine switched on with insufficient air for more than 15 min-

utes!

Error when converting GF

data. GF data most likely cor-

rupted from the line com-

puter.

Cycle power on the line computer and all stations. Most likely

GF data defective with a newly created GF.

Printed circuit board feed er-

rors.

Check sensitivity of the sensors. Check the center sensor for

contamination.
