Alarm signal output function to external output terminal
If the average current/voltage (average per second) during welding falls outside the tolerance range set by "P41" to
"P44", the external output terminals set by the internal functions will be shorted. (
6.7.2.20
-
F25 to F28: External
output terminal setting
）
The shorted external output terminals open when any of the following conditions are met.
- When some key on the panel is pressed while the alarm is displayed and normal display is restored.
- When the torch switch is set to “ON” while an alarm is displayed to start welding (only when P46 is set to "0")
- When operation is stopped by releasing 3-4 (operation stop terminal) on the external connection terminal
block TM3 during alarm indication, and then the operation stop is canceled by short-circuiting these
terminals (only when F4 setting is "1" or "2").
7.2.2.5
Total operating time
Total operation time and total welding time are managed according to the display range.
•
P50 (Cumulative total operation time)
The operation time of welding power source is counted at all time and accumulated as total operation time. The setting
range of count value is between 0 and 9999 hours.
Refer to P52 (Clear the control data) about how to clear "P50".
•
P51 (Cumulative total welding time)
Every interval from the start of current flowing triggered by the start signal ON to the stop of output triggered by the
start signal OFF is counted and accumulated as welding time. The setting range of count value is between 0 and 9999
hours. The time between 0 and 99.9 hours are displayed in the unit of 0.1 hour and the time exceeding 100 hours is
displayed in the unit of 1 hour. The count value of "P51" will not be cleared according to the "P32" setting.
Refer to P52 (Clear the control data value) about how to clear "P51".
•
P52 (Clear of the control data value)
Clear the various control data. After setting the setting value of P52 to “cLr”, return to the MENU screen. Then, the
control data shown below will be cleared.
7.2.2.6
Alarm indication when target is achieved
When any of the number of welding points, wire consumption and total welding time reaches the target specified, its
corresponding control No. will flash.
7.2.2.7
Alarm indication at the time of WARNING detection (Welding Monitor "P45" "P46")
If the average current or average voltage becomes out of the specified range, the difference between the average value and
the specified value will flash.
P50 (Cumulative total operation time)
P51 (Cumulative total welding time)
•
In the right example, the control No. "P20" flashes on the left digital
meter and the specified value "910" on the right digital meter.
•
The display returns to the normal state when any key of the operation
panel is pressed.
•
If continuous operation is enabled in the setting of the operation for
the time when the target is achieved, an alarm will display every time
welding finishes until any key of the operation panel is pressed.
<Example> When wire consumption reached the target value
•
The right example shows a current error. The control No. "P40"
flashes on the left digital meter and the difference between the
average value and specified value "30" on the right digital meter, with
the "A" LED lighting.
<Example> While welding is conducted with the welding current
200 A/Current tolerance (+) 10% (=220 A), the average current
during welding rose to 230 A and the WARNING judgment time
specified in "P45" elapsed.
