6.5 Weld Cycle State Displays and Alarms
When the welder is turned on, it performs a number of internal system tests. If any errors
are encountered, the welder will not enter the READY state, If no errors are encountered,
the welding parameters are set to those stored. An error in reading the settings will cause
cold values to be used.
Upon successful completion of the internal tests, the welder enters the READY state and
you will see READY displayed on the numeric display. At this point, you can set weld cycle
parameters (as described in Section
6.2 Setting Weld Cycle Parameters.
If the welder does not successfully complete the internal tests and you receive an error
message, refer to Section 6.5.1.1 Weld Cycle Alarms and Error Messages for a definition
of the message.
6.5.1 Weld Cycle State Displays
During a normal weld cycle, the eight-digit NUMERIC DISPLAY shows the current weld
cycle state as indicated below.
Table 6.9 2000IW State Displays
State Description
S0
One START SWITCH Pressed/Wait for Second START SWITCH - The currently
active welding parameters are stored in NOVRAM (non-volatile memory)
and a 100 to 200 ms stagger timer is started, during which time the other
START SWITCH must be pressed or an alarm will be generated and the
welder will return to READY state.
S1
Both START SWITCHES Pressed/Wait for SV (Solenoid Valve) Active - When
both START SWITCHES have been pressed within 100 to 200 ms of each
other, the SV circuit is activated and a 4 sec. timer is started, during which
time the SV signal must become active or an alarm will be generated and
the weld cycle aborted.
S2
SV Active/Wait for ULS - When the SV signal is activated within the timeout
period, a 4 sec.timer is started, during which time the ULS signal must
become inactive or an alarm will be generated and the SV signal
deactivated.
In addition, if either START SWITCH input is lost (where the START SWITCH
input status is defined as “Maintained”), an alarm will be generated and the
SV signal deactivated.
