General notes

Handling boards

ESD protection All the boards described in the following are fitted, among other things, with

large-scale integrated circuits. Voltage impulses caused by static charging

from people or objects can easily destroy the circuits.



When handling boards, ensure that the electronics cannot be damaged by

static charging or discharging.



Place the printer on an earthed underlay before opening it.



Earth your body with an ESD protective armband or by using another

suitable means. If suitable ESD protection is not available, touch an

earthed object, e.g. a radiator, before touching a board.



Only place boards on an earthed underlay.

Handling The conductor lines on modern multilayer boards are very thin. Bending the

boards can therefore easily break the conductor lines.



Avoid bending the boards.



Avoid using excessive force when removing and installing the boards.

Connecting the board



Connect the CPU board as illustrated:

Fig. 1: Right half of the CPU board.

Adjusting the sensors

Adjust the sensors as follows:

1. Call the parameter SERVICE FUNCTIONS/ Sensor test. Use the Feed

button to select the relevant Sensor No.

2. Assure, that the concerned light barrier (LS) is free (not covered).

3. Alter the setting of the potentiometer, until the greyed value in the table

appears on the display. Read the value for:

– punch- and reflex sensor on the printer control panel.

– material end sensor on the display of a voltmeter applied at measuring

point TP6 (GND =Frontal pins of all connectors on top of the power

supply).

Output stage board

General notes

There are two different versions of the output stage boare in circulation

(see ). T he newer board doesn´t require any setting of the sensor by

potentiometer any more. Therefore, the pots are missing in the newer

layo ut (=disti nguishi ng f eature).



Please keep in mind the following points, when you replace or check an

output stage board:



PIC version:

The PIC must carry a label with the writing "M04A V3 C73"!



Jumper setting:

The jumper setting must match the motor which is ought to be driven by the

output stage!



See paragraph Jumper settings on page 9.



(only older board layout) Sensor setting:

The sensor current must amount 25 mA!



See paragraph Sensor setting on page 10.

Layout

Jumper settings

Each of the applied three, four or five printer motors is controlled by a

separate output stage board. The boards only differ from each other in the

jumper setting (Fig. 3:).



Set the jumper.

Sensor setting



This description is only valid for boards with the older layout (recognizeable

by the two blue pots). T he newer board version doesn´t have to be set!

1. Turn printer off, disconnect the sensor cable from connector "Sensor",

switch printer on.

2. Measure the current with an amperemeter as shown (see Fig. 5:).

3. Turn potentiometer P1 until you measure 25 mA.

Fig. 5: The current between the measuring points A and B must amount to 25 mA. If not,

use P1 to set the current.

4. Switch printer off, connect sensor cable, switch printer on for functionality

test.

Functionality test

1. Call the parameter "SERVICE FUNCTIONS / Sensor test":

Sensor Test

0.04 Matend xxx

xxx =Numeric value

0.04 =Sensor number

2. Press the feed button repeatedly until the appropriate sensor number (see

Tab. 3:) shows up.
