- Error codes.

3.4.1

 

- Yellow led (B) lit, with fix light.

Alarm for temperature above limits.
The thermostat is located on the dissipater of the power mosfets of the power board (15).
The power source delivers no current, but the fan remains in operation; we therefore

recommend leaving the power source powered in case of alarm for overtemperature.

Check the temperature of the dissipaters of the power modules on the power board (15), and if

necessary wait for them to cool completely. If the alarm persists, replace power board (15). If the
alarm is reset, check the efficiency of ventilation, make sure the ambient temperature is not too
high, and that the working cycle is not greater than the one specified.

3.4.2

 

- Yellow led (B) flashes at 50%.

Alarm for high supply voltage, greater than approximately 290 Vac, at start-up.
The power source delivers no current.
The power source returns to operation, when the voltage becomes lower than approximately

285 Vac.

This system also protects the power source against accidental power supply at 400 Vac. In

this condition the electronic circuits are protected, but the fan is subjected at mains voltage, can
be damaged in few seconds.

3.4.3

 

- Yellow led (B) off, during first 3 seconds after start-up (no lamp-test).

Alarm for low supply voltage, less than approximately 180 Vac, at start-up. The power source

delivers no current, also if leds signaling status is the same of normal operation after lamp-test.

The power source returns to operation, with the normal  pre-charge sequence, when the

voltage becomes greater than approximately 185 Vac, remaining at reduced performance levels
until the voltage approaches the rated value.

3.4.4

 

- Yellow led (B) flashes (two fast flash with 1,5 seconds pause).

Alarm for low supply voltage, less than approximately 160 Vac, during operation.
The power source delivers no current.
The power source returns to operation, when the voltage becomes greater than respectively

165 Vac approximately, remaining at reduced performance levels until the voltage approaches
the rated value.

3.4.5

 

- Yellow led (B) flashes (three fast flash with 1,5 seconds pause).

Alarm for inside driver circuits supply voltage excessive. This is generally a phenomenon

which may damage the power source if you continue working.

To restore operation, shut off the power source, wait for the capacitors inside to discharge

completely (4 minutes), and restart the power source at the rated voltage.

If the alarm returns, replace the power board (15).
