Maintenance; Cleaning - Cebora EVO 260 T Manual De Instrucciones

11.2.1 CAN-1 on Power Source.
The CAN-1 line, present on CN1 connector, is headed to
the J5B connector of control board (see par. 14).
− Power supply. Is generated by the control board (+8
Vdc) and made available on the connectors and J5A
J5B, (pin 1(+) 2(-)) of the control board (J5A and J5B
are connected in parallel one to each other).
− Terminating resistors. SW1 on Power Source rear
panel is provided:
• SW1 = OFF, resistors not inserted; in case of sys-
tems with equipments (Wire Feeder unit, Console
Plasma etc.) connected to CN1 connector (CN1
busy);
• SW1 = ON, resistors inserted; in case of systems
without equipments connected to CN1 connector
(CN1 free).
− CAn function. Default setting is only available.
11.2.2 CAN-2 on Power Source.
The CAN-2 line, present on CN2 connector, is headed to
the J5C connector of control board (see par. 14).
− Power supply. Is generated by the control board
(+10Vdc, approximately) and made available on
J5C connector (pin 1(+) 2(-)) of the control board.
The positive output (pin 1) of this internal source is
decoupled with a series connected diode, so that it
can be used an eventual external supply source, with a
voltage equal to or greater than 10 Vdc.
− Terminating resistors. SW2 on Power Source rear
panel is provided:
• SW2 = OFF, resistors not inserted; in case of Power
Source not connected to the Robot Interface or Ro-
bot Control (CN2 free);
• SW2 = ON, resistors inserted; in case of Power
Source connected to the Robot Interface or Robot
Control (CN2 busy).
− CAn function. Set the Technical menu "CAn func-
tion" (par. 10.14.16).
11.2.3 CAN-1 on Control Panel.
The CAN-1 line is headed to the CAN1 connector of panel
board (see par. 14).
− Power supply. Must be provided to the panel board
CAN1 connector, (pin 1(+), 2(-)) from an external
source (+8Vdc). Normally from control board.
− Terminating resistors. SW3 on panel board is pro-
vided (for inspection remove the control panel by un-
screwing the two side pins that secure it to the frame on
the Power Source front).
• SW3-1 = SW3-2 = OFF, resistors not inserted;
• SW3-1 = SW3-2 = ON, resistors inserted.
NOTE
Sections 1 and 2 of SW3 must always be in position equal
one to each other (both ON or both OFF).

MAINTENANCE.

12.1 Periodic inspection, cleaning.
Periodically make sure that the Welding System equip-
ments and all connections are in proper condition to ensure
operator safety.
Periodically open the Power Source and Cooling Unit
panels to check the internal parts.
Remove eventual dirt or dust from the internal parts, using
a jet of low-pressure dry compressed air or a brush.
Check the condition of the internal power connections and
connectors on the electronic boards; if you find "loose"
connections, tighten or replace the connectors.
To ensure proper air flow and thus adequate cooling of the
internal parts of the Power Source, periodically open the
grids on the Power Source and check the internal parts of
the aeration tunnel.
Remove eventual dirt or dust from the internal parts of the
tunnel, using a jet of low-pressure dry compressed air or
a brush.
Check the condition of the electrical connectors, power
cord and pneumatic connections; replace if damaged.
After making a repair, be careful to arrange the wiring in
such a way that the parts connected to the power supply
are safely insulated from the parts connected to the weld-
ing circuit.
Mount the clamps as on the original machine to prevent, if
a conductor accidentally breaks or becomes disconnected,
a connection from occurring between power supply and
the welding circuits.
12.2 Firmware update.
For the Cebora Welding System equipments programming
or Firmware update there are two distinct methods:
− with "Cebora Device Manager";
− with "USB pen-drive".
12.2.1 Cebora Device Manager.
"Cebora Device Manager" is a program, downloadable
from the Cebora web site http://www.cebora.it, that has
to be installed into a PC with Windows Operating Sys-
tem, equipped with RS232 serial port or appropriate USB
adapter.
Connecting the PC to the Power Source (connector BO),
is possible to program both the Power Source and all the
devices connected to it (Control Panel, Robot Interface,
Feeder Unit, Plasma Welding Console).
In the Cebora web site are available the program files to
install in the equipments (files named *.ceb or *.fwu) and
the Instructions Manual to help in using Cebora Device
Manager.
