CHAPTER 7
– WELDS COUNTER FUNCTION
The control unit is fitted with the same number of weld counters as the number of selected
transformers or welding tools. As such, the operator can count the spots carried out with each
welding head or with each different tool so as to manage the consumption of the electrodes
and the current increases according to the spots carried out in actual fact by each electrode.
During the process, the display shows the counter of the spots carried out by the transformer
or tool associated with the last weld program used. The counters increase at each weld cycle
carried out by the tool associated with the counter. The weld cycles carried out in NO WELD
mode are not counted.
The welds counter may be cleared when the control unit is in work configuration.

Reset by pressing the CLEAR
key on the TE700 control unit front panel. In this case the
following message is displayed:
CLEAR COUNTER
UP / DN TO SELECT:
RESET COUNTER T1?
<+> OK <-> CANCEL
If only one welding transformer or tool was selected, then only the T1 counter can be reset.
Press key <+> to reset the counter or key <-> to leave the counter value as it is.
If a number higher than one was selected for the welding transformers or tools, use keys
and
in the foregoing screen either to choose which counter to reset or reset all the counters
of the spots associated with the tools used. If more than one tool was used, press the CLEAR
key to view the request for resetting the counter associated with the last tool used. Press key
<+> to reset the selected counter or all the counters. Press key <-> to leave the counters
value as it is and return to the work screen.
The spots counters may also be reset through the external control line only if optional board
code 50200 is installed. In this case the activation of the signal to change the electrodes
resets the spots counter. If only one spots counter is available it will reset automatically but if
multiple counters were activated, which counter is to be reset is selected with recall lines
RIC1, RIC2 and RIC3 according to the following table.
