The Alarm Latch DIP switch setting determines whether Latchable alarms
are Latching or Non-Latching. Use Switch 1, 5 Alarm Latch Status:
•
ON = Alarm Latch Enabled.
Latching
•
OFF = Alarm Latch Disabled
Non-Latching
For further information on setting DIP switches, refer to Section 3.9.
a.
Latchable alarms
Latching
alarms prevent a new weld cycle from starting and can only
be cleared by pressing RESET or activating the EXTERNAL RESET
signal.
Note:
The reset circuitry requires 30 rns to clear an alarm Before
cycling; therefore, if RESET is pressed for less than 30 ms,
the welder will not return to the READY state.
Non-Latching
alarms are displayed on the front panel and generate
output signals through the accessory interface. All Non-Latching alarms
are cleared when the next cycle is started (by PALM BUTTON or start
cable) or they will clear by themselves after 1.5 sec.
b.
Non-Resettable alarms
Non-Resettable alarms prevent the welder from cycling. They are
caused by hardware failure. You must turn the welder OFF, correct the
situation and then turn the welder back on before you can start the
next weld cycle. These alarms cannot be cleared by pressing RESET or
the EXTERNAL RESET signal.
