POWER SUPPLY
The vending machine should only be connected to earthed electrical systems.
Before connection to the supply mains, make sure that the earthing system is present, that the supply
voltage is 220-230 Volt~, that the outlet to which the machine will be connected is in good condition and
approved for at least 10 Amp and that an omnipolar switch is installed upstream of it, i.e. that switches
off both power supply conductors with a single opening action (except for the earth conductor), with an
opening of the contacts of at least 3 mm. (It is recommended that the outlet have an insulated residual
current breaker).
Install the vending machine so that the power-supply plug is easily accessible after you install it.
Check the appearance of the power cord to detect possible abrasions or other defects of the sheath or
of the plug on the cord and replace it if necessary as described further on in this manual.
-POWER CORD REPLACEMENT
If it should become necessary to replace the vending machine‟s power cord, the H05VV-F replacement
cord, which is in conformity with standard CENELEC EN 60 335-1, is available from Damian; the
replacement should ONLY be carried out by skilled service personnel.
Before all operations on the power cord, make sure that the power-supply plug is disconnected
from its outlet.
Remove the rear grille of the cabinet by unscrewing its fixing screws, remove the cable gland from the
grille, open the cable gland and remove the cable.
Disconnect the cable socket from the electrical box and remove the cable to be replaced.
Repeat the operations described above in reverse order to install the new cable.
Check that the main switch found on the lower part of the cabinet (See Fig. 2) is in the “OFF” position
and insert the plug into the power-supply outlet, then move the main switch to the “ON” position.
When the vending machine door is closed, all of its electrical parts will be powered owing to the
pressure exercised by the door on the safety switch (black switch located on the left bottom of the
vending machine. See Figure 2).
USING THE SAFETY SWITCH
The vending machine is equipped with a safety switch (See Figure 2) that allows powering up all of its
electrical parts only when the door is closed. When it is necessary to power up the vending machine
with the door open (for example, for loading products or programming), the safety switch can be armed
by inserting the special key and turning it 90°. To disarm the safety switch (in order to cut off power to
the electrical parts), turn the switch key 90° and remove it from the switch.

OVERTEMPERATURE CONTROL (ONLY MODELS LXS9P/X/XX-S)
In order to guarantee the preservation of the products for sale, the vending machine controls that the
internal temperature does not exceed a given threshold, called safety temperature, for a period longer
than the overtemperature time;
The overtemperature control function is managed through 3 parameters:
- (A) Safety temperature
- (B) Overtemperature time (Set).
- (C) Restocking time
The overtemperature is only controlled in mode operating of the refrigeration unit = „Food & Snack‟,
setting the (A) Safety temperature parameter to a value below 40 °C
During normal vending machine operation, if the internal temperature exceeds the “Safety temperature”
(A) for a period longer than the “Overtemperature time” (B), the “ERR L09” error will be generated,
which will put the drawers set in the „Food zone‟ of the vending machine out of order.
The period of time in which the vending machine is off is always considered beyond the “Safety
temperature” (A).
If the vending machine is turned off and then on again (e.g. after restocking), the “Overtemperature
time” (B) is prolonged by a value equal to the one set in the “Restocking time” (C) parameter.
Each time it is turned back on, if the internal temperature exceeds the “Safety temperature” (A) but the
conditions for generating the “ERR L09” error have not occurred (see above), the following message
will appear on the display for approx. 15 sec.:
XXX = Missing minutes,
YY,Y = Internal temperature,
ZZ,Z = Safety temperature.
(by missing minutes (XXX) we mean the minutes within which the internal temperature (YY,Y) must go
below the safety temperature (ZZ,Z) to prevent generation of the “ERR L09” error).
If the “ERR L09” error has been generated, entering into programming you will be asked if you wish to
reset the out of order by zeroing the error.
Press key 1 to reset the error
Press key 2to NOT reset the error
IMPORTANT: the values of these three parameters should be set in accordance with the current
regulations applicable to the preservation of sold products. See the programming parameters in
Attachment "A" for how to set them.
N.B. To prevent false out of order indications following prolonged operator intervention, it is possible to
initialise the counters through the “Overtemperature counter reset” function (Refer to Attachment A,
“Programming Sheet”).

that the bracket (14) that presses the switch is adjusted properly. Replace the switch or the bracket if
necessary.
Check the motor (11) of the sliding panel (10) and the relative wiring. Replace it if necessary.
-UPON TURNING ON “ATTENZ.VERIFICA PANNELLO SCORREV.” IS DISPLAYED.
When the vending machine is turned on, during the test of opening and closing the sliding panel, and
wrong opening and closing times of the sliding panel values are found, it is suggested to perform a
calibration of these values.
To calibrate sliding panel time/speed of opening/closing, enter into “Diagnostic” in the “Sliding panel test ”
menu (see relative chapter).
-UPON TURNING ON “WARNING OUT OF ORDERS DETECTED”IS DISPLAYED.
During normal vending machine operation, some malfunctions of some motors may occur. These
malfunctions generate errors that can be automatically reset by the vending machine (R)* or that can be
"not resettable" (NR)* and put the selection out of order (see above).
Even if operation of the selection has been automatically reset when the machine was turned on, the error
remains stored and must be deleted manually in diagnostics to keep the message from reappearing.
To check which motors and which problems have been stored, enter into “Diagnostic” in the “out of order
motors ” menu (see relative chapter).
-WHEN MAKING A SELECTION “SELEC.X-X IN OVERTEMPERATURE”IS INDICATED
If some selections are out of order indicated by the “Selection xx in Overtemperature” message, this is due
to the intervention of the “refrigerator safety control” (ERR L09 refrigeration unit timeout error) which has
put the drawers set in the vending machine „Food zone‟ out of order (see Overtemperature control”
section).
Entering in programming, you will be asked if you wish to restore operation by resetting the error.
Press key 1to reset the error
Press key 2to NOT reset the error
When key 1is pressed the selections will be active again.
-WHEN MAKING A SELECTION “SELECTION X-X NOT ACTIVE”IS INDICATED
If some selections are out of order indicated by the “Selection x-x not active” message, this indicates a
problem relative to the storing of the configuration, because the selection made is not stored as active by
the vending machine.
Make sure that you have made the correct selection.
Carry out the “Motor Verify” procedure found in the diagnostic menu.
Carry out a new self-learning procedure of the motors through the reset of the circuit board.
If the motor is not recognised during the self-learning procedure, see the relative error further on.

-WHEN MAKING A SELECTION “SELECTION X-X OUT OF ORDER”IS INDICATED
If some selections are out of order, indicated by the “Selection x-x out of order” message, this indicates the
presence of a problem relative to the motor.
For a detailed analysis of the type of error that generated the out of order condition, use the “Diagnostic”
menu, “out of order motors” submenu and the preceding chapter “Motor anomaly messages”.
NOTE: It is possible to cancel the “Out of Order” condition of the motors without entering into programming
by pressing the PS2 key found on the CPU card for approx. 3 seconds (See Fig. 7).
-SOME MOTORS ARE NOT DETECTED DURING THE SELF-LEARNING PROCEDURE.
Check the wiring and good condition of the unrecognised motors, as well as the good condition and correct
insertion of the connectors on the bottom of the vending drawers.
After performing the above, carry out the procedure indicated for the “Disconnected motor” error.
-SEVERAL MOTORS RUN SIMULTANEOUSLY
When making a selection, two or more motors, even far apart, run simultaneously.
Check that a motor connection was not inverted following a maintenance operation. The motor with the
inverted wiring might not be among those that rotate simultaneously.
Check the good condition of the wiring of the motors of the vending spirals.
Replace the motor and/or connection wiring if necessary.
Make sure that the “Twin motors” function is not activated.
If the problem persists, make sure that the CPU card works and replace it if necessary.
-THE MACHINE DOES NOT REACH THE REQUIRED TEMPERATURE
Before carrying out any operation on the refrigeration unit and, in particular, before checking
any electrical part, move the main switch to the “OFF” position (See Figure 7).
Check the condition of the fuses (See the “Fuse check” chapter).
Make sure that dust and foreign materials do not block the refrigeration unit air passage.
Check that the condenser cooling fins are not blocked by dirt or foreign bodies and clean them if necessary
(to access the refrigeration unit, see the “Refrigeration unit disassembly and reassembly” chapter.
Check that the set temperature is neither too high nor too low, referring to the programming sheet.
Check that the internal air circulation fan works correctly.
Check that the refrigeration unit compressor works and that the cooling fan (located between the
compressor and the condenser of the refrigeration unit) works properly. If the compressor does not start
working when the LED on the card indicates that it is activated, check and if necessary replace the electric
starting capacitor, the Clicson or the amperometric relay located in the box mounted close to the
compressor.
With the compressor operating, check that the evaporator actually gets cold.
Check that the two evaporator fastening hooks located on the shelf under the first drawer are closed and
the evaporator properly hooked.
If it is not possible to identify the cause of the problem, contact an authorised service centre.

-DISASSEMBLY AND REASSEMBLY OF THE REFRIGERATION UNIT
Before carrying out any operation on the refrigeration unit and, in particular, before checking
any electrical part, move the main switch to the “OFF” position (See Figure 7).
On the LXS9 automatic spiral vending machines it is possible, with simple operations, to remove and
perform maintenance on the refrigeration unit, extracting it from the front of the vending machine.
Follow the instructions given below to disassemble (See Figure 6 for the references given in
parentheses):
-Open the vending machine door completely;
-Without removing it, pull out the first drawer on the bottom and unhook, turning them 180 degrees,
the two hooks (a) that restrain the refrigerator evaporator to the lower shelf of the cabinet, reclose
the drawer.
-Remove the product collection tray (b) by releasing the three push hooks (c) found at the sides of
the tray;
-Remove the screw knob (d) that fastens the refrigeration unit to the base and disconnect the power
supply wiring of the refrigerator from the electrical box;
-Grasp the handle (e) at the base of the refrigeration unit and remove it from the normal work
position by pulling it, if necessary, until it is completely extracted.
To reassemble the refrigeration unit, follow the operations described above in reverse order, i.e.:
-Being careful not to damage the vending machine‟s power cord, centre the evaporator of the
refrigerator in the guides of the cabinet shelf under the first drawer, slide the refrigerator on the
vending machine base until it is back in the normal work position;
-Secure the refrigerator to the base with the special screw know and reconnect its power cord to the
electrical box.
-Reassemble the product collection tray, fastening it with the three push hooks found at the sides of
the tray itself:
-It is very important to remember to reclose the two evaporator fastening hooks located on the shelf
under the first drawer, otherwise you could compromise the correct operation and duration of the
refrigerator;
-The refrigeration unit is now ready for use.
