7.2.1.2 Fault in the Vibrator Activation

●

An individual vibratory feeder (vibrator) in the activated feeder sector/location (1; 3) is failing to

convey components

Possible causes:

–

The vibratory feeder will not activate (Check: "Refill track"

→

select linear feeder): electrical interrup-

tion in the vibratory feeder or in the power supply cable; poor contact in the plug connection at the

connections panel.

–

Interruption in the 24 VAC supply voltage at the corresponding connection socket (LED on the con-

nections panel illuminates) or the vibrator controller of the communications unit: check the plug con-

nections; if necessary, replace the communications unit.

–

The period of time for vibrator activation has been input incorrectly (see User’s Manual for the UNIX

line computer, Section 5, under "Coordinates Correction").

–

The vibration intensity has not been set correctly at the potentiometer rotary button (on the connec-

tions panel of the communications unit): see below, section 7.2.1.2 "Fault in the Vibrator Activation".

–

The basic calibration of the vibratory feeder needs readjusting.

–

There is no vibrator (= vibratory feeder) defined in this track: see User’s Manual for the UNIX line com-

puter, under "Feeder Part Editor".

●

The vibratory feeders of an entire feeder sector or location (1; 3) are not being activated

Possible causes:

–

No vibratory feeders are defined at this location (see User’s Manual for the UNIX, under "Feeder Part

Editor").

–

There is no voltage at the components table: the fuse on the input side of the transformer components

table is defective (leads to error message "Communication with table faulty"): see section 7.3 "Compo-

nents Table Power Supply".

–

Defect in the vibrator control circuit; interruption within the communications unit: replace communica-

tions unit.

7.2.1.3 Fault in the Flap Opener (Magazine Opener)

●

An individual flap opener will not activate, the plunger does not extend / retract

Possible causes:

–

No linear vibratory feeder or 24/32 mm tape feeder module (blister tapes) has been defined for this

installation point or track (see User’s Manual for the UNIX computer, "Feeder Part Editor").

–

The "Components supply - flap openers" ribbon cable is defective; there is a bad plug connection:

replace the cable.

–

The associated solenoid valve is not switching: electrical interruption on the "Flap opener controller"

board or the solenoid valve on this board is defective: replace controller board.

●

Flap opener plungers do not extend or retract far enough

Possible causes:

–

Compressed air for the flap opener has been incorrectly set at the compressed air unit (setting should

be 2.8 bar, see User’s Manual, Section 9).

–

Pressure loss in the compressed air branch for flap openers: check threaded hose connections,

replace pinched compressed air hose.

–

The corresponding compressed air cylinder in the flap opener is defective: replace the compressed air

cylinder.

●

Flap openers of an entire feeder sector (locations 1 or 3) are not being activated

Possible causes:

–

No linear vibratory feeder or 24/32 mm tape feeder module (blister tapes) has been defined at this

location (table 1; 3) (see User’s Manual for the UNIX computer, "Feeder Part Editor").

–

After fault correction or reinstallation: The ribbon cable plug has been plugged into the board "Flap

opener control" incorrectly (plug misaligned with socket).

–

The 30 VDC electrical circuit has been broken by the fuse (see section 7.5 "Communications Unit").

–

Break in the ribbon cable; interruption in the communications unit or in the components table interface

cable (output signal from the control unit not present).

7.2.1.4 Fault in the Components Table Pneumatic System or

Components Table Compressed Air Supply

●

An individual compressed air feeder module is not conveying:

Possible causes:

–

The feeder module has not been positioned correctly; the locking device at the end of the module has

not engaged and closed.

–

The associated pneumatic adapter in the components table compressed air supply is leaky: replace o-

rings, replace pressure spring

→

see section 7.7 "Components Table Pneumatics, Components Table

Compressed Air Supply".

–

The solenoid valves in the compressed air feeder module are not switching:

–

The compressed air feeder module has not been defined on this track (see User’s Manual for the

UNIX line computer, "Feeder Part Editor").

–

Solenoid valve(s) in the feeder module is (are) defective; electrical interruption in the module or in

the connecting cable of the module (see the Service Manual for the module).

–

Interruption within the communications unit: replace (see section 7.5 "Communications Unit").

●

None of the compressed air supply modules of a location is being activated or conveying correctly

Possible causes

–

At this location (1; 3) no compressed air supply modules have been defined (see User’s Manual to the

UNIX line computer, under "Feeder Parts").

–

Compressed air for the components table compressed air supply has not been set precisely to 5 bar:

for setting, see the section 7.7 "Components Table Pneumatics, Components Table Compressed Air

Supply".

–

Pressure loss in the compressed air branch (5 bar) from the compressed air unit to the components

table compressed air supply.

–

Break in the components table interface cable (signal not arriving from the control unit). See also:

error message "Communication with table interrupted".

7.3 Components Table Power Supply

DANGER

QQQ

Before you start work on the components table power supply, the components changeover table must be dis-

connected from the mains (mains plug, on the righthand side of the machine base).

Please note with all work in the machine base interior and in particular on the components table power supply

the stricter VDE 0113 safety regulations.

7.3.1 Tools and Spare Parts Required

Auxiliary Measuring and Test Equipment

●

Ohmmeter

Spare Parts

●

Miniature fuse 5x20/T3,16AT, from Item No. 00304938-01

●

Cable: control signals, components table Y558-W1, from Item No. 00300380-06

●

Cable: power, components table Y545-W1, from Item No. 00300379-03

NOTE:

With error message "Communication with table interrupted" the fuse F1 at transformer T1 could be defective.

Carry out preliminary fault location with the aid of the section 7.2 "Fault Characteristics".

Details of the components table power supply will be found in the Overview section, the corresponding circuit

diagrams in the current circuit diagrams folder: diagram 1710460-Y0928-...-L-.../-Y0558-..-L-.../-Y0545-...-L-..

7.3.2 Replacing Fuse F1

●

Select "Abort placement" to return all picked-up components.

DANGER

QQQ

Switch off the machine at the main switch and disconnect it from the power supply.

●

Undo the plug connections of the components changeover table at the machine base on the right beside

the components changeover table (mains and interface connector X37 and if applicable the pneumatic

connection).

●

Open the protective covers and pull cover at the components loading point upwards and away.
