Message text Problem description / solution
OFF L01... Temperature probe 1 error
–
These messages indicate a problem with the probe that measures the
temperature inside the vending machine. This probe is located on the inner right wall, near the 1
st
low
drawer towards the bottom of the vending machine.
Note: Probe operation is only checked at the moment the vending machine is turned on.
OFF L01a Probe 1 defective (Disconnected)
– Probe 1 disconnected error.
- Turn the vending machine off and then on again, verify in programming that the
temperature value read by probe 1 is correct (see programming sheet). Try
touching the probe; if the value shown on the display does not change, check the
wiring and replace the probe if necessary.
- If, once the probe has been replaced, the problem is repeated, the fault might be
due to the CLP1 power board located in the electrical box.
OFF L01b (Short-circuit) - Probe 1 short-circuited error.
- Turn the vending machine off and then on again, verify in programming that the
temperature value read by probe 1 is correct (see programming sheet). Try
touching the probe; if the value shown on the display does not change, check the
wiring and replace the probe if necessary.
- If, once the probe has been replaced, the problem is repeated, the fault might be
due to the CLP1 power board located in the electrical box.
OFF L02…. Temperature probe 2 error –
These messages indicate a problem with the probe that measures the
temperature of the refrigeration unit evaporator. This probe is located in the refrigeration unit located
under the central plane of the machine. The refrigeration unit must be removed to access the probe (see
specific chapter).
Note: Probe operation is only checked at the moment the vending machine is turned on.
OFF L02a Probe 2 defective (Disconnected)
– Probe 2 disconnected error.
- Turn the vending machine off and then on again, verify in programming that the
temperature value ready by probe 2 is correct and that the probe is not immersed
in ice; otherwise check the probe wiring and replace the probe if necessary.
- Check the vending machine configuration to verify if this probe should be
present. If not, carry out a new self-learning procedure as indicated in the
programming sheet attachment.
-
If, once the probe has been replaced, the problem is repeated, the fault might be
due to the CLP1 power board located in the electrical box.
OFF L02b
(Short-circuit) - Probe 1 short-circuited error.
- Turn the vending machine off and then on again, verify in programming that the
temperature value read by probe 2 is correct or that the temperature of the room
is not above 45 °C. If the error is not reset, check the probe wiring and replace
the probe if necessary.
- If, once the probe has been replaced, the problem is repeated, the fault might be
due to the CLP1 power board located in the electrical box.
OFF L04 Executive OFF (Executive OFF) - No communication with the Executive system.
- Check the 24Vac power supply coming from the transformer and the connection
of the relative wiring with the 15-pin connector.
- Check the Executive signal wiring.
- If the problem is not resolved, check CPU card operation.
