The parameters can be changed only if they have been enabled
by entering the password from
Abi
menu.
The modification is also possible with a modbus address of the
board equal to Ø.
Abi (enabling change of setpoint and parameters)
The
Abi
menu has the following functions:
•
enables the change of heater setpoints under
Set
menu;
the password is one (1);
•
enables the change of parameters under
Par
menu; this
password is used by CATs and is indicated in the table of
Paragraph 5.6 "Modulation PCB Parameters".
Once the password is enabled, if no key is pressed for 10 minutes,
the programme automatically returns to the machine status.
Move using the menu arrows, select the parameter or setpoint
to be displayed with ENTER, change the parameter by pressing
the arrow keys until the desired value, then press and hold
ENTER
for at least 3 seconds; the display flashes to indicate
that the value has been stored.

Flt Menu (Fault)
It displays the fault event log; use the arrow keys to scroll the
list of error codes and press
ENTER
to display the historical
value of the selected fault.
The first visible value,
rst
, is used to reset the fault event log; this
operation must not be performed by the user but by the service
centre. The reset operation can be carried out by changing the
parameter to 1 and confirming it by pressing and holding
ENTER
for at least 3 seconds. After the reset,
rst
returns to 0.
The list and meanings of all faults are shown in the FAULT table
in Paragraph 5.7 "Analysis of Lockouts - Faults".
