The adhesive points

are smeared

The outside of the nozzle is dirty. Check the nozzle diameter and, if the glue

cleaning pad is approached cyclically, reduce

the number of large adhesive points.

The point volume is too large. Adjust the point volume.

You are using the wrong spacer. Compare the spacer against the correct val-

ues.

Adhesive points are

missing

The nozzle is clogged.

(See below for possible causes)

Clean the nozzle.

The spacer is too large. Fit a spacer that matches the reference value.

The spacer ran into an obstacle (clinch, raised

galvanized pad, etc.)

Change the spacer angle and enter the values

in the program under ’Gluing parameters’. The

new values will not take effect until you restart

the software.

You have used a poor quality adhesive.

This means that the adhesive becomes irregu-

lar and stringy during continuous application

- They break off early and are puckered,

- when the solenoid valve is manually actu-

ated, a drop of adhesive forms on the nozzle

and is then pulled back again.

Check the shelf life of the adhesive.

Follow the manufacturer’s storage instructions

on the data sheet.

Replace the glue cartridge.

The temperature of the adhesive is too low. Increase the temperature.

The PCB is contaminated (by fingerprints,

grease, dust or environmental influences, for

example).

Use clean PCBs.

Eliminate the cause of contamination during

the production sequence.

The z-axis moves jerkily. Clean the cam disc with ethyl alcohol and

notify the Service department.

The first adhesive point

is missing

The ’use by’ date of the adhesive has passed. Use a new cartridge.

The sealing ring on the cartridge seal is miss-

ing or worn.

Insert a new sealing ring and grease lightly

with Unisilkon.

The glue cleaning pad is not approached. Activate the glue cleaning pad in the machine

options.

Software error mes-

sage: ’Spacer in con-

tact with glueing point’

The adhesive point sequence has been opti-

mized with respect to speed, but not with

respect to the spacer angle.

Change the spacer angle and enter the values

in the program under ’Gluing parameters’. The

new values will not take effect until you restart

the software.

The spacer is touching

the adhesive point

The mechanically set spacer angle does not

correspond to the data in the gluing parame-

ters.

Correct the angle and enter the values in the

program under ’Gluing parameters’. The new

values will not take effect until you restart the

software.

The adhesive point diameter is not included in

the computer model.

Change the spacer angle and enter the values

in the program under ’Gluing parameters’. The

new values will not take effect until you restart

the software.

Large points lead to

incorrect measure-

ments in the adhesive

point check

The adhesive points are smeared. Clean the nozzle, carry out the adhesive point

check with adhesive point volume factor -4 (-5),

accept the proposed measurement and do not

carry out any further measurements.

Metering stage 20

causes ’mounds’ to

form on the PCBs and

the points smear on

the paper roll

The adhesive properties have changed. Reduce the volume.

Increase the size of the spacer.

You are using a new

adhesive and have

entered the parame-

ters in the MA data, but

the quality is poor and

the points are smeared

See ’Smeared points’

The new adhesive has very different flow prop-

erties

Select a larger spacer than the one specified.

The diameters differ

greatly within a charac-

teristic curve

You are using the wrong spacer. Insert the correct spacer.

If the compressed air is switched over, the

metering pressure between two successive

point sizes will change.

The different metering pressure has caused

the point to be built up slightly differently. This

may cause the diameter of a larger metering

stage to be smaller than that of the previous

metering stage.

The PCB flexes when the adhesive points are

applied.

Insert the PCB support.

The adhesive characteristic curve is incorrect. Load the correct characteristic curve and

restart the machine. In the Single functions, set

the cartridge to ’full’. PLEASE NOTE: If the

cartridge is no longer full, you must insert a

new cartridge.

You have loaded a new

characteristic curve,

but the point sizes are

still incorrect

You did not set the cartridge to ’full’ after load-

ing the characteristic curve.

Insert a new, full cartridge and confirm using

the ’New cartridge’ function.

You must not confirm a ’New cartridge’ after

changing the spacer angle.

The z axis causes a

crash

The clamping rails is bent. Check the clamping rail and straighten or

replace it, if necessary.

The zero point correction for the z axis is incor-

rect.

Check the zero point correction and reset, if

necessary.

The motor or tacho is defective. Notify the Service department.

The adhesive point

positions migrate on

the PCB

The PCB is not clamped sufficiently because

the clamping rail is bent.

Check the conveyor belt and set the PCB

transport width.

The PCB has not been set down correctly. Check the conveyor belt and set the PCB

transport width.

The x/y scale is dirty. Clean the scale with alcohol.

The connection between the incremental

encoder and mini gantry motor is defective

Visually inspect the motor,

notify the Service department.

The nozzle has been

damaged

The nozzle is colliding with defects on the

PCB.

Check the PCB for defects (screws, bent

leads).

The nozzle is colliding with hard objects (the

nozzle is made of aluminum).

Check the storage conditions and handling

when the nozzle is inserted.

The clamping rail is bent. Check the clamping rail and straighten or

replace it, if necessary.

The nozzle is clogged You have stored the nozzle in alcohol / spirit. If you clean the nozzle with alcohol / spirit, sim-

ply rinse it out afterwards. Then immediately

blow the nozzle out with compressed air.

(Long-term contact with alcohol will cause the

adhesive to harden, even at room tempera-

ture).

We recommend that you use the cleaning

agent Zestron HC.

Replace any nozzles with hardened-on adhe-

sive residues.

❏

The nozzle has been in use for too long. Clean the nozzle as described in the mainte-

nance instructions.

Replace any nozzles with hardened-on adhe-

sive residues.

’Error in DP from the

line computer’

The programmed metering stages cannot be

used with the specified characteristic curve.

Adjust the characteristic curve and the range of

metering stages. Reprogram the metering

stages, if necessary.

The data in the placement program is incor-

rect.

Press <F1> to switch screens and read the

detailed error message.
