5.4. MEASUREMENTS:

Precautions before working on the appliance:

Check voltage range OK: 190-240V- in certain cases the appliance will not function at 200V - the

check is aimed at identifying 210 V at which the appliance must function; the fault is indicated by

ﬂ ashing of the display / power indicator lights

Check for possible burns on the connections

Check of wiring and ﬂ at connection cable between generator and control PCB for possible cuts

due to external causes

Check rated voltage on generator power supply from ﬁ lter (220V)

Voltage measurement 12V DC at two ends

Voltage measurement 5V DC on second from left and last

Hobs - 2006

1. NTC on generator approximately 100 K (generates

a fault anyway and inhibits operation of the plate

assembled with the relative NTC)

2. Voltage regulator: 12 V detected between central and

left and 5V between central and right: UNDERVOL-

TAGE CONDITIONS!!!

3. IGBT: there are three contacts on this device: a mea-

surement taken between any two of them must not
