The resistor is composed of three heating ele-
ments which in conditions of perfect operation
give typical values of about 30/33 Ohm. To detect
whether there are damaged elements, place the
tester probes on the elements of the same colour
as shown in the figure.
5.3 HEATING ELEMENT AND
HEAT PROTECTION
The main heater of VA388 T3 has the following
resistances:
t 8GPSUIFVOJUWFSTJPO
t 8GPSUIFVOJUWFSTJPO
Fig. 119
There are three heating elements, one for each
phase, therefore, in the terminal box we find the
neutrals connected in parallel (N) and the three
phases which arrive each to a different element,
perfectly distributing the absorption of the current.
If you need to remove the heating element to be
cleaned from limestone or replaced, it will be suf-
ficient to disconnect the connections with a 6 mm
wrench and unscrew the four bolts with a 13 mm
wrench.
