TROUBLE-SHOOTING
Operational failure
Cause
Procedure to be followed
1.
The furnace does
not heat
(and furnace indicator
light on)
1.1.
Thermocouple
The main display shows
"
dF
sond
" (probe fault).
-
Check the continuity of the thermocouple with
an Ohmmeter or a sound test.
-
If you do not have such device, a visual
examination will inform you on the level of wear
(the wire should not be cut).
-
Replace the thermocouple: see chapter 9.3.
Press the P key to remove the faulty probe on the
furnace (programs reset).
1.2.
The muffle (the heating
element) is cut
-
Remove the back panel and check resistance at
the muffle with a multimeter:
-
Programix 50: 24 ohms
-
Programix 100: 15 ohms
-
Replace the muffle as indicated in chapter 9.4.
2.
The furnace does
not heat
(and furnace indicator
light off)
Programming
-
Check the program: temperature and time
values.
3.
The furnace heats
continuosly
Of that happens just after
changing the thermocouple.
It is because the positive or
negative wires have been reversed.
In this case, the furnace displays
the room temperature all the time.
-
Connect correctly the thermocouple’s polarity:
+ : green wire / - : white wire
NOTE: the negative wire (white) is slightly
magnetic (check with a magnet).
4.
The fume
extractor goes out
Programming
-
Check the extractor stop temperature.
In the standard setting, the extractor stops at
650°C.
In all cases, if the failure persists, contact the after-sale service.
