ACTIVE ALARMS
The Active Alarms Screen has three primary areas (see Figure 30.1). Current Values displays the current values
that could trigger an alarm. Edit Values allows you to change the alarm trigger thresholds. Active Alarms dis-
plays what alarms are currently triggered. Individual alarms can be enabled or disabled using the rocker switch
on the screen. Simply touch the switch to toggle between enabled and disabled. The thresholds that the various
alarms can occur can be edited by touching the box under the Edit Values column and entering a new value.
When the circle is gray and to the left, the alarm is disabled. Move the circle to the right to enable the alarm.
The PA250i has six different alarms:
•
Temperature:
This alarm will notify you once the internal temperature crosses your preset temperature
threshold. When the alarm is active and enabled, the fans will turn on. Sunstone has also programmed in
critical temperature value thresholds, where the fans will turn on regardless of alarm status, and in event
of critically high temperatures, welding will be disabled. Once the temperature decreases below the
threshold, the alarm will be inactive.
•
Misfires in a Row:
This alarm will notify you once the number of weld misfires in a row crosses your
preset threshold. The unit considers it a misfire when it detects a weld was attempted but the weld
energy did not successfully discharge. Once a weld successfully discharges, this count will reset to 0
and the alarm will be inactive.
•
Alarm: Weld Counter 1:
This alarm will notify you once the number of welds crosses your preset
threshold. This counter will only reset to 0 when the Reset Button is pressed, which will also deactivate
the alarm.
•
Alarm: Weld Counter 2:
This alarm will notify you once the number of welds crosses your preset
threshold. This counter will only reset to 0 when the Reset Button is pressed, which will also deactivate
the alarm.
