PHENOMENON
ERROR
This is a safety error.
If heating is running and heating resistances are switched o
, then
the control board shall switched to the FUNCTION_CHECK state
(functional relays o
, safety relays on): here the program shall
check. If condition is not satis
ed for at least 15 s, the error
condition shall occur elsewhere if the elapses without detecting the
error, thi s condition shall not be checked anymore (all relays shall
be switched o
).
Error
Relay Stuck
This is a safety error.
If NTC1 probe is well (no NTC1 shorted or open error condition
detected), the dry heating error test can be carried out: if
temperature > 115 °C for at least 3 s, the dry heating error shall
be set. Similarly, if NTC2 is working and temperature > 115 °C for
at least 3s.
This is a not volatile error: the machine shall be locked until the
error is removed with a reset condition.
Error
Dry Heating
This is a safety error.
If NTC1 probe is well (no NTC1 shorted or open error condition
detected), the the overheating error test can be carried out: if
temperature > 1
0
5
°C for at least 3 s, the the overheating error
shall be set. Similarly, if NTC2 is working and temperature > 1
0
5
°C
for at least 3s.
This is a not volatile error: the machine shall be locked until the
error is removed with a reset condition.
NTC
High/Low
Overheating
This is a safety error.
It shall be detected during the initialization routines anytime data
ash is
the machine shall be locked.
This is a not volatile error and it shall be removed only resetting the
machine.
Error Bad
Data Flash
corrupted and there is a loss or an overwriting of data; if so
1.1> Some typical error/ warning.
This is a safety error.
The control board shall not allow more than 5 reset attempts for not
volatile errors in 15 minutes. Every time these reset attempts occur,
a timer initially set to 15 minutes shall decrease; there shall be
5 timers (each one starting from 15) and a further reset shall be
accepted if at least one of them is zero. If all of them are not null, a
sixth timer shall be enabled: this timer shall increase its value of 5
minutes (until 255 minutes at the most) each time a further logical
reset is attempted: when this timer is not null timers 1-5 shall not be
checked and the CANT UNLOCK condition shall occur.
Reset shall be allowed again only when CANT UNLOCK condition is
removed: this shall happen when timer 6 and then at least one of the
first 5 timers become zero.
