Control of cooling fan

The supply air cooling fan for units 61 - 102 behind the control panel is

controlled by a converter 230V AC - 24V DC.

The air filter under the control panel can be replaced by simply unlocking

it from the base frame.

The cooling air is discharged through the bottom of the unit.

The supply air cooling fan 201-202 on the rear left back panel is controlled

by a transformer pri. 230V AC, sek. 12V DC.

The air filter can only be changed after dislodging the protection cover

and sliding it to the right side.

The cooling air is discharged through the top left side of the rear panel.

Both supply air cooling fans are equipped with a temperature sensor

(NTC). This sensor measures the temperature at the position of the clima

valve Y5. The speed of the cooling fan increases with increasing tempera-

ture.

This sensor can not be changed separately.

The DC (supply air) cooling fan always runs when either of the following conditions are given:

B4 Temperature is above 130°C (266°F) or the CPU temperature is above 60°C (140°F) or any cooking

process is selected.

Additional 230V cooling fans distribute the cooling air in the electrical cabinet and cool the SSRs.

If the pcb reaches a temperature of 65°C (149°F) - depending on unit type- , “Change air filter” will be

displayed. If a temperature of 80°C (176°F) is reached, any running cooking mode or program will be

terminated and error “Service 29” is displayed.
