CEBORA S.p.A.
2.4 - Programming power source art. 285 (firmware upgrade).
The control board (27) contains the main microprocessor of the power source and the memory
to set up the parameters of the work programs and synergic curve charts.
Programs and synergic curves are defined based on the experience earned by Cebora, and may
be upgraded thanks to a programming system that uses the programming board (21) (connector
J1) and a RS232 serial communication line.
The upgraded programs are available, together with the "Cebora Downloader" programming
software and the relevant instructions, in a single programming file available at the web site
www.cebora.it.
2.5 - Restoring the factory setting.
Work programs may be changed by altering the parameter set-up available from the control
panel. These customizations may be saved in the memory of the control board (27), and be called
up thereafter using the "Save" and "Recall" procedures described in the Instruction Manual.
The following procedure makes it possible to restore the parameter set-up to the standard
values assigned when the power source leaves the factory.
With the power source off, press and hold down the keys (O) and (R) simultaneously, and
switch on the power switch (U) (16).
Hold the keys down until "dFL" (default) appears on the display (G).
Release the keys (O) and (R) and wait for the parameters upgrade to be completed, after
which time the normal start-up sequence will begin automatically.
2.6 - Customized synergic curves.
The power source 285 may operate with standard synergic curves, contained in the memory of
the control board (27), or with customized synergic curves developed by Cebora on request by
the customer.
The customized curves are released in the form of 2 programmed EEPROM memories (one
with the curves of the conventional programs (Hxx) and the other with the curves of the pulsed
programs (Pxx)), to be inserted in slots A and B of the programming board (21).
The EPROM may also be installed in the slots individually and without having to observe a
particular position. Upon start-up the power source checks for the presence of the EEPROM, and
automatically activates the following operating modes:
with EEPROM not installed the power source operates according to the synergic curves
−
resident in the memory of the control board (27).
−
with EEPROM installed in the slots, the power source operates according to the synergic
curves stored in the EEPROM. This mode is indicated by the led (A) "HOLD" on the
control panel, which lights while display (G) shows the codes of the curves, "Hxx" and
"Pxx", during start-up.
2.7 - Back-up procedure.
The following procedure copies the synergic curves resident in the memory of the control
board (27) to the EEPROM installed in the slots of the programming board (21).
With power source powered, press and hold down simultaneously the (O) and (R) keys and
the start button on the torch, until the codes of the curves being copied (Pxx or Hxx) appear on
display (G) (P = pulsed, H = short, xx = progressive number of the curve).
Release the keys (O) and (R) and wait for the parameters upgrade to be completed for both
EEPROM, after which time the normal start-up sequence will begin automatically.
The back-up procedure always also resets the parameters to the factory values.
