The Purpose is that all mechanical relays
switch powerless. Therefore they are control-
led according to the below switching dia-
gram.
The diagram above shows the 4 blowers of a
5 tray oven. One of them is “opened”, sho-
wing the coils.
The matrix above shows which Spd relays are
switched ON at different fan speeds.
It also shows which voltages can be expected
at a 230V connection or 200V in case of a
200V unit (Japan).
Finally it shows what capacitor loads are con-
nected in the different oven models.

1. The 3 Spd relays and the DIR relay are swit-
ched in the good position.
2. The SSR switches the power ON
3. The R relay takes over.
4. The SSR relay switches OFF.
5. After 45 seconds, the SSR switches ON.
6. Now the R relay can switch OFF powerless.
7. The SSR switches the power OFF.
8. The DIR and Spd relays can now switch
powerless.
9. The above relays get a new position.
The DIR relay stays OFF --> the direction
changed.
10. The sequence repeats from #2.
The switching sequence.
