A Fan alarm (only for T75E)
- The fan motor is provided with a thermal protection that stops the motor in
case of excessive absorption; allow the motor to cool down before rebooting,
after eliminating the cause of failure.
B Moto compartment alarm (TT96E - TT98E only)
- If the motor compartment temperature unusually exceeds the maximum
threshold, a thermal switch automatically turns on and cools the oven; allow
the oven to cool down and check the rear cooling fan functions properly
(Fig.38 part Y) before restarting oven. Two baking fans are included by
default in TT96E and TT98E ovens.
C Temperature limit alarm.
- If the internal temperature unusually exceeds the limit, the safety thermostat
automatically turns on and blocks the oven ; unscrew the the safety
thermostat's (fig.14 part P) hood to restore the oven's operation , after having
cooled and ensured that no component is damaged, and press the button below
to reset the thermostat; reposition the protective hood to prevent the thermostat
from damage and breaking down the oven. Only TT98E: The oven has two
independent safety thermostats with manual reset: one for the left side fig.14
part P). and one on the right side of the oven (fig.36 part G).
D Communication error
-Indicates that communication between the electronic boards is compromised.
Ensure that the cards are powered appropriately and connections are intact.
E Thermocouple alarm
-This indicates that the thermocouple is damaged or disconnected. In TT98E:
the display also indicates which thermocouple is damaged, left or right.
F Conveyor belt alarm .
- The geared motor of the conveyor belt is provided with a secondary speed
control system; if it does not turn, the alarm will buzz.
The following SIGNALS may be displayed if there are any failures:
G Switchboard over-temperature (TT96E - TT98E only)
-This indicates that the temperature of the electric components compartment
has exceeded the threshold limit. Check the status of the rear cooling fan
motors (fig.38 part Y).
H Pressure switch Failure (TT96E - TT98E only)
-It inspects the integrity of the pressure switch. Contact specialized technical
assistance to resolve the cause of the failure; ensure that no oven component
was damaged and eventually replace it.
I Abnormal shut down
-displayed at start-up and indicates that the oven was previously turned off
incorrectly, and the provisions of paragraph 3.3. were not followed.
WARNING!
the abnormal shut down signal must not be taken into
consideration ONLY in the following cases:
1. there is a real condition of danger so the oven is switched off using the
emergency mushroom button (fig.14 part O)
2. there is a temporary and sudden interruption of electricity supply for
external causes not caused by the user.
In all other cases follow the procedure to switch off the oven
appropriately, otherwise it will break down permanently!
When there is a signal, the control unit shows the type of signal on the screen.
Press OK (fig. 29 Pos. 15 T75E-TT96E-TT98E and 29 pos. 16 T64E) to
acknowledge the visual and acoustic signal (if any) and the message
disappears. If necessary, finish baking and contact customer service.
3.2.20 CEILING-FLOOR
RESTRICTIONS (T75E - TT96E -TT98E only)
For better control and safety, the control unit has a default setting to include
the set point temperature restriction for ceiling and floor.
When the difference between the two temperatures exceeds 20°C (T75E) or
15°C (TT96E and TT98E), a parameter that cannot be changed by the user, the
temperatures are automatically changed to comply with the range described.
For example, in case of ceiling temperature increase above the limits
mentioned, the temperature of the floor will also change, and vice versa.
To free the temperature from this restraint, press MENU, select the DISPLAY
menu and press OK.
The items on the menu include "AUTOMATIC" which will be checked (√) to
show that the automatic display is enabled and that the temperatures being set
are bound to each other.
To de-activate this restraint, select "AUTOMATIC" and press OK to confirm.
If the automatic display is disabled and this function is required again, follow
the same instructions to reactivate it.
3.3 STOPPING
T64E
To stop the appliance, press the STOP button (fig.29 part 17); the fan and
movement of the belt will continue for about 30 minutes to bring down the
temperature gradually and safeguard the duration of the components;
only after this time should the power be disconnected turning the switch to
position "0" (fig.29b part E).
SET POINT TEMPERATURE
WARNING!
In an emergency, cut the power by turning the
main switch to "0" (fig. 29 part E).
T75E - TT96E - TT98E:
To stop the appliance, press the STOP button (fig.29 part 18);
the fan will continue for about 30 minutes to bring down the
temperature gradually and safeguard the duration of the components;
after this time and the time required to cool down oven parts, the oven
will switch off by itself.
WAIT for the display to darken.
After these steps:
- TT96E or TT98E will automatically switch off;
- T75E is switched off manually, turning the switch
(fig.14 part N), to "0".
NOTE:
Avoid abrupt shutdowns. If it necessary turning the oven off
before it switches off automatically, wait until it reaches a temperature
below 100° C(210°F). Hold down the STOP button for a few seconds (fig
29 pos. 18), the display will read "SHUTDOWN?"; press OK to confirm
the automatic switch off procedure for the control unit, or press RETURN
to cancel the operation and return to the main screen.
T75E - TT96E - TT98E
WARNING!
by pressing the emergency mushroom head button (fig.14 part O).
NOTE:
After the emergency mushroom head button has been
pressed (fig.14 part O) it will remain pressed in the safety position
until, once the emergency is over, it is unlocked by turning it
anticlockwise.
3.4 USE
After setting the desired baking parameters, prepare the product to be
cooked on a suitable support (pizza mesh, etc.), making sure that it does not
come out through the perforated part of the mesh; use a baker's shovel to
transfer it onto the conveyor belt at the baking chamber in-feed end, and it
will come out at the other end cooked.
If you have no experience regarding the values to be set, start baking at
temperatures of 310 °C (T64E-TT96E-TT98E 270°C), both for ceiling and
floor, and a baking time of 4 minutes, then vary the parameters according
to results until the settings are right for your needs. It takes approximately
25-35 minutes for the oven to get up to temperature, only start baking after
the temperature has stabilized.
WARNING!
cooked must be carried out with the aid of specific accident prevention
equipment, such as pizza shovels etc. (fig.15 part O) and with the
greatest possible care and attention; when the oven is working do not
approach moving parts for any reason. Any operations to be carried
out on the appliance must only be carried out after it has been turned
off.
The baking phases can be observed through the glass on the front door
where present.
Should it be necessary to make adjustments to the product, for instance to
remove air bubbles that may form on the pizza using a tool, this can be
done with great care after opening the door with the front handle (fig.15
part Q) where present.
WARNING!
accessed using tools, taking great care not to become hooked up on the
belt, and making sure that the tools do not pull the operator's limbs
into the chamber.
Under no circumstances must any part of the body be inserted into the
chamber, as there is a severe risk of burning or getting caught on the
belt and crushed by the belt itself.
WARNING !
burn and special care is required, especially if the belt is high up
compared to the operator.
