ALARMS/SIGNALS DISPLAY
T75E - TT96E - TT98E
The following types of ALARM may be displayed on the control unit
screen if problems are detected.
1) Belt stopped alarm
2) Fan stopped alarm (T75E only)
3) Max. safety temperature exceeded alarm
4) Motor compartment alarm (TT96E-TT98E: due to the lack of operation
by the rear cooling fan or to the intervention of the motor's thermal
breakers which switch off the motors as a protective measure)
5) Thermocouple alarm (the failed thermocouple will be indicated)
If any one of these alarms is triggered the control unit will indicate the type
of alarm on screen, and will shut down the oven.
A screen will be shown of the type illustrated in fig.33, featuring an icon
that represents the error at the centre of the display (fig. 31 part A), under
which there is an explanatory text message (fig. 31. part B).
The alarm, which is indicated both visually and by the buzzer, will
continue until the OK button is pressed. The alarm will continue to be
indicated even if the alarm conditions no longer exist: let us say for
example that the temperature exceeds the max threshold foreseen for a
moment, and then returns to normal values. The alarm condition has
ceased, but the alarm will still be displayed on the control unit monitor and
the oven will remain off until it is restarted. This is to allow the operator to
become aware of the problem, even if there was nobody in the vicinity of
the oven when it actually occurred.
If the "OK" button is pressed the display will return to the initial page and
the alarm message will no longer be visible, but this does not mean that it
no longer exists: if the problem is still present the alarm will be displayed
again as soon as the oven is started once more, the equipment is then set to
cool.
WARNING!
In the event of a malfunction or fault in the
appliance, stop the appliance following the steps in point 3.3.
For the TT98E, if there is an anomaly, the control unit screen will show
one of the following types of SIGNAL:
1) Contactor/pressure switch failure (during the start phase, it checks the
integrity of the power and pressure switch contacts)
2) Electrical part compartment over-temperature: Indicates a preset
threshold has been exceeded (check the operation of the rear cooling
fan, etc.)
When there is a signal, the control unit shows the type of signal on the
screen. Pressing "OK" notifies that the signal has been seen and heard and
the message disappears.
T64E
The following types of ALARM may be displayed on the screen (fig. 29
part D) if problems are detected.
1) ALL1 - General Alarm (baking fan, over-temperature in the motor
compartment, max over-temperature inside the baking chamber)
2) ALL2 - Thermocouple Alarm
3) ALL3- Electric panel over-temperature alarm
Leave the equipment to cool down and send for technical assistance to
remedy the cause of the failure and to make sure that no part of the
equipment is damaged.
In certain working conditions the oven may block and/or switch off, due to
one of the following causes:
- The conveyor belt gear motor is fitted with an electrical guard system that
stops the gear motor in the event of excessive power absorption.
- The fan motor is fitted with a thermal cut-out that stops the motor in the
event of excessive power absorption. To re-start, after removing the cause
of the problem, the motor must first be allowed to cool down.
- If the internal temperature exceeds the maximum threshold due to a
malfunction, the safety thermostat triggers automatically to block operation
of the oven; to restore normal operation unscrew the cap protecting the
safety thermostat (fig.14 part P) and press the button underneath to rearm
the thermostat; replace the protective cap to prevent the thermostat from
deteriorating and compromising proper running of the appliance. TT98E
only: 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).
WARNING!
turned on again, stop it following the procedure in point 3.3.;
disconnect the power plug from the socket and contact a specialized
service technician.
