P23 . Functional description of output signals
Pin Signal Function
4 ALLSTB
Same as ALLSTA but for channel B.
5 RICHRAV
Request for Dressing. Active at +24V.
This output is activated as a function of the programming of
the stepper concerned.
Consult the programming manual for the activation/reset of
this function. In the machine shutdown condition, the signal
can be reset only by setting the counter of the relevant
stepper to zero. This can be made via the RAVOK (P24-9)
input or through the software reset in the Stepper menu.
6 RICHEL
Request for electrodes change.
Active at +24V. Led indicator illuminated.
Same as for request for dressing but it devoted to the
electrodes change. The validation is to be carried out with the
CHGEOK (P24-10) input.
7 ALARM1
Signalling. Active at +24V.
It does not interrupt the processing cycle.
Diagnostic alarm (from E001 to E050).
Generally, it is reset automatically but it can be fitted with a
shutdown function in the Setup menu.
See chapters on Alarms and Setup in the programming
section.
8 ALARM2
Machine alarm. Active at +24V.
It shuts down the cycle.
It concerns faults, errors in programming and errors in wiring
of both the control device and the machine.
It can be reset by pressing the reset key on the small
keyboard or from the RESAH dedicated input.
It is active until the cause has not been removed.
9 UNDCURR
Undercurrent. Diagnostics. Active at +24V.
It does not shut down the cycle.
It is always activated together with the alarm 1, when the
current value read by the sensor is lower than the
programmed threshold. A number of causes may generate it,
e.g.: No current or limit threshold, etc…
It can be of use when intervention on faulty welds is needed.
10 OVRCURR
Overcurrent. Diagnostics. Active at +24V.
It does not shut down the cycle.
Same as Undercurrent but the current value is in excess.
11 READY
Control device ready. Active at +24V.
This output is activated when the control device is ready to
execute a welding cycle.
When Alarm1 or Alarm2 is generated, this output is low.
