Note
• Do not turn off the “CONTROL POWER” while “START”
input is in ON state. (If such a thing occurs, turn ON the
CONTROL POWER within 24 hours.)
If such a thing
occurs, counter values of monitoring items
(welding count, production count and step up
count) may be different from the actual ones as
they are reset to the value before START output is
turned on. However, such difference won’t be
treated as an error.
• After the welding counter or the production counter
reaches the preset value, it is necessary to reset the
counter to zero to turn on the next start.
To reset, do either one of the followings.
（
a
）
Turn on the appropriate reset input.
（
b
）
Use front panel keys
For welding counter reset:
Press “RUN” and “
-
” keys together.
For production counter reset:
Press “RUN” and “
+
” keys together.
*If the counter value is changed after it reaches
the preset value, the “COUNT UP” lamp is turned
off.
•The values displayed as welding and production
counter values are the accumulated values. To display
remaining values (i.e. the subtractive method), set the
DIP swith(DPSW2-3) to the ON side.
• The counters function even if the welding is performed
while
and (A) are displayed.
• The counters do not function (do not count) in the
“Current off” mode when the product is in the states of
test run, current upper or lower limit, full wave (when
the major trouble mode is selected), and no current
flow.
• When the counters are not required, set “0” to the
counter value. (The display for the counters becomes
blank.)

Step-up
（
1
）
In the setting mode, set the SOL No., and then set
the current incremental rate and welding count for
each step. (The set-up conditions can be set for
SOL
I
and SOL
II
separately.)
（
2
）
Press “RUN” key and press the “ENTER/SHIFT” key
three times, then the current step-up number and the
remaining welding count of the relevant step are
displayed on the data indicators A and B.
• After that, every time welding is performed, the
welding counter is reduced by 1.
（
3
）
If the “+” key is pressed in the above (2) state, the
current step-up is ended and the operation is shifted
to the next step.
（
4
）
After completion of all welding count preset in S0 to
S4, the step-up completion output turned on, the
“COUNT UP” lamp of the “STEP-UP CNTR.
(MONITOR)” lights, and the buzzer sounds.
• After that, the operation continues in the step-up 4
(S4) state while maintaining the output until the
“Step-up reset input” is turned on or the “step-up
shift” input is turned on.
Note
• The counter does not function (do not count) when the
product is in no current state, in “Current off” mode and
during the test run.
• When this function is not required, set “0” to both the
current incremental rate and welding count
.
