1. VES MATIC 20 / VES MATIC 20 PLUS - INTERVENTION PROCEDURES
(TROUBLE SHOOTING)
Before performing any type of intervention on the instrument:
a) SWITCH OFF THE ON/OFF SWITCH ON THE VES MATIC INSTRUMENT.
b) DISCONNECT THE INSTRUMENT FROM THE POWER SUPPLY IN ORDER TO
AVOID ANY RISK OF CONTACT WITH ELECTRICAL OR MECHANICAL PARTS
UNDER LINE VOLTAGE.
IF THESE BASIC RULES ARE NOT FOLLOWED, THE MANUFACTURER OF THE
VES MATIC 20 / VES MATIC 20 PLUS INSTRUMENT WILL ACCEPT NO
FURTHER RESPONSABILITY.
1.1. APPROACH TO THE VES MATIC 20 / VES MATIC 20 PLUS INSTRUMENT
1. Observe the recommendations reported in paragraph 1.
2. Open the outer covering of the instrument.
3. Gain access to the module of interest, as described in the procedures reported
hereafter (see Flow Chart no. 1).

1.2. ANALYSIS OF THE FAULTS
The faults reported in the following paragraphs make reference to the Trouble Shooting
procedures described for the individual modules, in order to demonstrate the type of
approach to follow in these situations.
1.2.1. The instrument does not switch on
a) Check that the mains power supply is working.
b) Check the power cable.
c) Check the fuses at the back of the instrument.
d) Check the ON/OFF switch on the back of the instrument.
e) Check the Power supply module (see procedure regarding Power supply).
1.2.2. The instrument switches on / Self Test
The instrument is switched on but the Self-Test is performed incorrectly, gives Error
codes, or is not performed at all.
a) The Self-Test is not performed
Check that the cover is closed - Close the cover.
Check the I/O board (see 5.5. procedure).
Check the CPU board (see CPU procedure).
b) The Self-Test is performed incorrectly - Error codes are visualized.
During the Self-Test the following Error Messages may appear on the display:
1) Error reading Error in reading of the Motor
Error in reading of the Home sensor (see 5.5. procedure)
Check the Home Sensor (see 5.5. procedure).
Check the Motors and Controls Board (see 5.5. procedure).
2) Error plate The sample plate holder does not move up and down
Check the UP/DOWN Sensor controlling the plate position (see 5.5. procedure)
Check the cabled Motor-reducer (see 5.5. procedure)
Check the Motors and Controls Board (see 5.5. procedure)
3) Error Mixing The Sample holder plate does not rotate
Check the Plate Motor (see 5.5. procedure)
Check the Plate Home Sensor (see 5.5. procedure)
Check the Home sensor stirrup (see 5.5. procedure)
Check the Motors and Controls Board (see 5.5. procedure)
4) Check Device exhausted The Check Device is not working
Check the Check Device (see 5.5. procedure)
Check the Motors and Controls Board (see 5.5. procedure)

7
1.2.3. The unit is on/display
a) The display visualizes but does not illuminate (backlighting )
b) The display does not visualize but illuminate
c) The display does not visualize and does not illuminate
d) The display visualize but the data can not be entered with the keyboard
See Display/Keyboard module procedure (5.3.).
1.2.4. The instrument switches on / Printer
a) The paper is not fed in; the printer does not print.
b) The paper advances but the printer does not print.
c) The printer prints but the paper does not advance correctly.
d) The printer prints in the compressed form.
e) The printer prints the wrong characters (see Printer procedure 5.4).
1.2.5. The instrument switches on / Check Device
a) The Check Device does not charge
Check that the Check Device is inserted correctly:
- Switch off the instrument
- Insert a new Check Device in the Check Device holder with the label facing the
operator (see operator manual, Check device procedure)
- Switch on the instrument.
If all is KO, check the Motors end Controls Board (see 5.5. procedure).
