necting it to the mains supply (208V~). The same spark
must arise. Do this a few times. The capacitor will not
be charged when the leads are disconnected during
the “zero crossing” of the mains sinus. It is ok when a
spark arises once.
Measuring with an Ω meter.
Be sure that the capacitor is empty!
The value will go up until
∞
Ω is reached.
Exchange the test leads. The value will go down,
through “0” and up again.
If not, the capacitor is broken.
If ok, it is still not sure if the capacitor is ok. It might
leak when it is connected to the mains power!
Active measurements.
You are about to measure on a 3 phase 230V~ circuit!!
You need to be qualified for this! Always work accor-
ding local legislations!
For measuring on the transformer terminal block:
• Use short test probes or-
• Unscrew the terminal block and turn it outwards
or-
• Turn out the glass panel.
Switch on the unit .
Voltages and Current that can be expected in normal
situation.
All voltages are related to a line voltage of 230V~
Blowers in high speed (speed 2 in cooking program):
• On the screw terminals of the blowers: 216V~
On the terminal block
• Between Black (1) and Blue (3):
229V~
• Between Black (1) and Red (6):
162V~
• Between Black (1) and Green (8):
216V~
• Current in wire 60 (2 blowers)
1,7A~
Blowers in low speed (speed 1 in cooking program):
• On the screw terminals of the blowers: 162V~
On the terminal block
• Between Black (1) and Blue (3):
229V~
• Between Black (1) and Red (6):
162V~
• Between Black (1) and Green (8):
216V~.
Trouble shooting with help of the I/O test facility.
• Open the settings menu
• Choose service and give in the pin code 4878
• Select “I/O test” and choose MFMB outputs.
3 keys are available to test the blower outputs. The
“X” numbers relate to the corresponding outputs
on the circuit boards.
X3 is the relay that switches high and low speed. “1” is
low speed.
X6 Switches power on the transformer.
X7 Not connected
Note that the text untill sw version 3.77 is not correct.
