3.0 CONTROL AND SAFETY DEVICES
The ovens are equipped with a set of control and safety devices for the electric and hydraulic circuits.
3.0A 2A fuse:
it is in the auxiliary circuit to protect against short circuiting of the electrical system and is
inside its own support on the contactor’s fixing bracket.
3.0D Motor overload protection:
a thermal probe disengages the motor when, for various reasons,
there is an overload. When the overload protection triggers it stops the motor and also disconnects the
heating elements or the gas valve. The probe is reset automatically when motor temperature drops.
3.0E Oven safety thermostat:
disconnects the heating element or the gas valve when anomalies
related to overheating occur. Reset will have to be done manually when causes for thermostat operation
have been determined.
3.0F Door micro switch:
it stops the oven working when the door is opened.
3.0G Thermostat system for condensation of discharge
steam
: (optional in conv humidification models): it com-
prises a solenoid valve controlled by a thermostat whose sensor
is housed in contact with the discharge.
The solenoid valve, via the injector (G), lets cold water into the
drainpipe to condense the steam when a temperature of 90°C is
reached (Fig. 3.0G).
Removing the side panel of the oven and acting on the F3 ad-
juster of the Pic.3.0G1, it’s possible to modify the condensation
system in the following way: if you turn the thermostat pin F3
counterclockwise until you hear a click, the function is disabled.
If you turn the pin counterclockwise without reaching the limit
stop, steam condensation system activates when the tempera-
ture in the drain pipe is around 30° C.
If you turn the pin counterclockwise till limit stop, condensa-
tion system activates when the temperature inside the drain is
around 90°C.
In our factory the ovens are supplied with F3 thermostat regu-
lated at 90°C.
3.0
H Oven relief valve
: its job is to adjust humidity inside the
cooking chamber.
The valve is manually activated acting on the knob (A)
(Fig.3.0H) on top of the door.
