Features
Input "External Parameter 1 Bit 1"
Input „Preselection Referencing
without measure"
Output "Spot selection error"
Output "Warning limit consecutively
Output "Linked to discrete input bit 1"
7.1.8

Weld complete

The output „Weld Complete" will be set after a sequence as long the input „Start"
is high. The precondition is that the sequence reached at least the weld time. A
Sequence is not finished before a programmed "automatic reweld" has been
executed.
7.1.9

End of Sequence / Abortion of sequence

After a finished respectively aborted sequence in case of no error the output
"Weld OK" will be set. In case of an error the output "Weld not OK" will be set.
The output will stay until the reset of the errors. The confirmation works via the
inputs "Reset fault" or "Reset fault with WC" or with a new start.
Exception:
• "Function test without component" is set
• Sequence without current
In these cases none nor the output "Weld OK", neither the output "Weld not OK"
is set.

7.1.10 Weld Enable

If the input "Weld Enable" is low during the start of a sequence an error message
occurs. The execution of the sequence is not possible.
If the Input becomes low during the sequence after the squeeze time, the
sequence is continued.

7.1.11 Supervision of Residual Current Protection Device

The Residual Current Protection Device (RCD) is supervised (Input "e.l.c.b. (earth
leakage circuit breaker) ok"). If an activation of the RCD is observed (Input
"e.l.c.b. ok" low) an error message occurs. The fault message is automatically
reset when RCD is deactivated (Input "e.l.c.b. ok" high).

7.1.12 Specifics about inputs

State of input "External Parameter 1 Bit 1" is registered in weld current log.
Via the input the timer decide if the timer starts after referencing automatic a tip
measure.
If the input is not set, no measurement run will be done.
If in this case there are no tip to tip actual values from the last measures
available, then the error "Position tip to tip unknown" will be set.
While comissioning has to be done a measurement run with new tips at this gun.

7.1.13 Specifics about outputs

Output "Spot selection error" will be set, if the selected spot does not correspond
to a program.
Output "Warning limit consecutively violated" will be set if the corresponding error
violated" occurs and stays high until the reset of the error.
Output is the negation of input "e.l.c.b. OK".
