OFF L21… CLP1 POT (16) circuit board errors.
These error messages concern failures of the vending
machine‟s power circuit board located in the electrical box (9).
OFF L21a CLP1 POT Error (Chk cable, Chang) - CLP1 power board (in the electrical box) error
- Turn the vending machine off and then on again; if the problem persists, check the
connections between CPU (2) and electrical box (9); check the USB cable.
- Open the electrical box and check the CLP1 card (16) power supply (the LED on
the card must be lit up).
- If the problem persists, replace the CLP1 power board (16).
OFF L21f
OFF L21g
CLP1 POT SW Err. (Reinstall SoftW.) - Power board (in the electrical box) software error
- Turn the vending machine off and then on again; if the problem persists, update the
software.
- If the problem remains after the update, replace the CLP1 power board (16).
OFF L22a Keyb-SENS Error Capacitive keyboard card error
- Turn the vending machine off and then on again; if the problem persists, check the
connections between CPU (2) and the K-SENS capacitive keyboard.
- If the problem persists, replace the K-SENS capacitive keyboard.
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.

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;
