07 -Communication Error In Can-Bus Detected By Master Panel Board (70); 09 - Communication Error Detected By One Slave Board; 10 - No Voltage Or Current At Output; 11 - Start-Up With Load Already Connected - Cebora KINGSTAR 400TS Manual De Servicio

CEBORA S.p.A.
3.6.4- 07 -Communication error in CAN-BUS detected by master panel board
(70)
Active only in "ROBOT" applications.
Communication error between master board (70) and "ROBOT", detected by master
board (70).

3.6.5- 09 - Communication error detected by one slave board

Communication error between microswitch board (37) and master panel board (70).
"ERROR 6" appears on master panel board (70), "ERROR 9" appears on wire feed unit
panel board (212).
In both cases, follow instructions for TESTING POWER SUPPLY TO MICROSWITCH
BOARD (42) and TESTING POWER SUPPLY TO PANEL BOARD (72), check wiring
between CAN1 microswitch board (37) and connector J2 on panel board (70), carry out
the tests in sections 3.5.1 and 3.5.3
Update power source software (see section 2.6), especially if microswitch board (37) or
panel board (70) have been replaced.
Replace microswitch board (37) and/or panel board (70).

3.6.6- 10 - No voltage or current at output

When the power source is turned on, the control checks operating conditions by running
a short no-load output voltage generation test
On this occasion, it is important to ensure that the torch does not touch the workpiece to
be welded or the welding bench.
Error 10 indicates that upon power source activation or with the inverter in operation,
the output voltage and current detection circuits on control board (37) read voltage = 0
and current = 0.
This situation is possible only in the following cases:
-
with a faulty inverter, i.e. that does not generate alternating voltage in the primary
winding of transformer (53) (section 3.5.8);
-
with one or both voltage and current detection lines interrupted (section 3.5.7);
Perform the no-load tests, section 3.5.9)

3.6.7- 11 - Start-up with load already connected

In the start-up phase the power source detected the presence of a non-negligible load
at the output. Disconnect the load and/or check the power voltages of output current
sensor (25). If necessary, replace output current sensor (25).

3.6.8- 14 - Microprocessor power voltage error on the microswitch board (37)

Follow instructions for TESTING POWER SUPPLY TO MICROSWITCH BOARD (37) in
section 3.5.1 and section 3.5.3, in particular the error occurs when +15 Vdc voltage is
outside the acceptable range.

3.6.9- 20 - No interlock signal

The "interlock" signal is supplied by a jumper between terminals 3 - 4 of J2 of Item No
372 (J4 on Item No 374) on power board (48) and is used to ensure that power board
(48) is connected to control board (37) (line of the current reaction signal to the primary
winding of transformer (53)).
