7.2 AUDIO WARNING OF PROBLEMS

When there is an error, the display will show a reading like this:

The displayed code allows to find the type of error which has caused the alarm and theinterruption of the correct machine operation.

The error signallings which may occur are shown below:

PROBLEM 2: The cooling fin's temperature is too high.Solution:

• Check if the air intakes are clogged (turn off the power before carrying out any type of cleaning).

• Check if the cooling fan is functioning correctly.

If the problem persists stop the sealing and heat-shrinking operations, turn off the power supply and replace the electronic panel.

PROBLEM 3: The heat shrinking reading temperature is not stable.Solution:

• Turn off the power supply.

• Check if the ground connections are correct (including those of the MAINS).

• Check if the thermocouple's connecting terminals are well locked;

• Replace the resistor equipped with thermocouple.

• If the problem persists stop the sealing and heat shrinking operations, turn off the power supply andreplace the electronic panel.

PROBLEM 4: Value read by the thermocouple to the maximum value.Solution:


• Check the thermocouple's connection.

• Check if there is a resistor lower than 5Ohms at the ends of the thermocouple with a ohmmeter. Checkif the tension is lower than 70mV with a millivoltmeter. This test must be carried out with the plantswitched on. If one of the two tests has negative results, replace the resistor equipped withthermocouple

If the problem persists stop the sealing and heat shrinking operations, turn off the power supplyand replace the electronic panel.

PROBLEMA 5: Temperature higher than the set valueSolution:


• Check if the outlet connector has been inserted correctly.

• Connect a voltmeter (bearing > 240 Vac) to the ends of the oven resistor terminals. Insert the powersupply and make sure there is voltage only with the heat shrinking mode and that the icon shows"oven resistors activated". If not turn off the power supplies and replace the electronic panel

PROBLEMA 6: Temperature lower than the set value.Solution:


• Check that the thermocouple connection has correct polarity.

• Check the thermocouple resistors connection.

• Check the heat-shrinking resistors.

• If the problem persists, stop the sealing and heat-shrinking operations, turn off the power supply andreplace the electronic panel.

PROBLEM 7: Overload outlet 24 volts.Solution:


• Check that the electromagnet connecting cables are intact.

• Measure the electromagnet resistor that must be 100-200W. If not change the electromagnet.

• If the problem persists replace the electronic panel.

ERROR 9:EEPROM errorAn anomaly has occurred during data storage.Solution:

• Press the key + and then reset the correct machine model

If the problem persists, switch the machine off and call the servicing centre.

PROBLEM 15: Problem NTC.• The reading of the NTC temperature presents a value that is not normal.

• If the problem persists turn off the power supply and replace the electronic panel.

N.B.: The card contains a control system on possible malfunctioning of the software. If a resetof the card occurs during functioning report the problem to the producer immediately indicatingthe release of the programme in use.
