20. TROUBLE SHOOTING
BEWARE : BEFORE ANY INTERNAL INTERVENTION, disconnect the power source from the power
supply. Internal voltages are high and dangerous
POSSIBLE CAUSES CHECKING / REMEDY
DIGITAL DISPLAY AND ORANGE INDICATOR F20 OFF
= NO SUPPLY
ON/OFF main switch is OFF Put the switch ON
Power supply cable is cut Check cable and connections
No main supply Check circuit breaker and fuses
Defective ON/OFF main switch Replace the switch
DIGITAL DISPLAY OFF AND ORANGE INDICATOR F20 ON
= INPUT VOLTAGE OVER RATED LIMIT
Input voltage > 260 V Check supply voltage
Power source supplied between 2 phases (400V) Connect the machine to proper line voltage (230V)
DIGITAL DISPLAY SHOW « tH » AND ORANGE INDICATOR F20 ON
= WARMING UP
Duty cycle over rated (particulary if ambient t°
is > 25°C) Let the machine cool, it will automatically start again
Insufficient cooling air Clean the air inlets
Very dusty machine Open the machine and blow it through
Fan doesn’t start Replace the fan
