Problem description / solution
OFF L20… CL1 CPU (2) circuit board errors.
These error messages concern failures of the
vending machine
‟s
circuit board.
OFF L20a
OFF L20b
CL1 CPU Error
(Restart - Change) - CPU card error
- Turn the vending machine off and then on again; if the problem persists, replace the
CPU card (2).
OFF L20f
OFF L20g
CL1 CPU SW Error (Reinstall SoftW.) -
CPU card software error
- Turn the vending machine off and then on again; if the problem persists, update the
software.
- If the problem is not resolved after the update, replace the CPU card (2).
OFF L50 (xxxx)
Unforeseen generic error.
- Turn the vending machine off and then on again; if the problem persists, contact
the technical assistance service, providing the number in parentheses.
O
THER ANSWERS TO PROBLEMS THAT MIGHT ARISE
Before checking any electrical part, move
the main switch
to the “OFF” position (See Figure 7).

ESSAGES RELATIVE TO MOTOR ANOMALIES
.
During the selections or Diagnostic tests some motor anomaly messages might appear on the display;
these messages are listed below with the relative explanation, as well as some possible solutions to the
problem:
“
Motor xx Disconnected
” (NR)*: The motor is not connected to the CPU.
Check the connections and that the motor wiring is not interrupted.
Check correct operation of the motor microswitch and of the motor itself.
Try replacing, one at a time, the motor; the CPU card; the drawer and cabinet wiring.
“
Motor xx Short Circuit
” (NR)*: The motor is short-circuited.
Check the good condition of the motor itself.
Check that the motor and its connections are not wet.
Check the connections and that the motor wiring is not short-circuited.
Try replacing, one at a time, the motor; the CPU card; the drawer and cabinet wiring.
“
Motor xx blocked
” (R)*: The motor is blocked or absorbs too much current.
Check the correct assembly of the vending spiral.
Check the motor connections, especially the correct polarity of the power supply (+/-).
Check that the spiral or motor are not blocked by poorly arranged products or various residues.
Try replacing, one at a time, the motor; the CPU card.
“
Motor xx Time Out Error
” (R)*: The motor appears to work but the microswitch does not work correctly.
Check correct operation of the microswitch, of the motor and the good condition of the motor itself.
Check the motor connections, especially the correct polarity of the power supply (+/-).
Try replacing, one at a time, the motor; the CPU card.
“
Motor xx Mot. Switch Err.
” (NR)*: The motor appears to work but functions anomalously.
Even if the error can be reset and the motor appears to work, if this error is repeated it is advisable to
replace the motor.
If the error is repeated even once the motor has been replaced, the wiring must be checked;
“
Motor xx Max 3 Selec Err.
” (R)*: The motor has been put out of order after three consecutive sales of
the same motor without detecting that the product has dropped
(See “FTCA Parameters” chapter).
Check that the spiral is hooked correctly to the motor.
Check the operati
on of the product drop control sensors (See “Diagnostics” chapter).
* = The error is automatically reset (R) or not reset (NR) upon turning on.
