ULS Inactive/Wait for TRS - When the ULS signal becomes inactive within
the timeout period, a 4 sec. timer is started, during which time the TRS
signal must become active or an alarm will be generated and the SV signal
deactivated.
In addition, if either the ULS or LLS signals become active, or one of the
START SWITCH inputs is lost (where the START SWITCH input status is
defined as "Maintained"). an alarm will be generated and the SV signal
deactivated.
Once the TRS signal becomes active, the weld parameters established for
Weld Time, Hold Time, AB Delay and AB Time are applied. Ultrasonic energy
will remain on until the specified Weld Time has elapsed, the LLS signal
becomes active (if the LLS function has been enabled), and overload occurs,
or the TRS input is lost.
Following successful completion of Weld Time, the SV drive circuit will
remain active for the duration of the specified Hold Time (unless TRS input
is lost). If specified, the parameters for AB Delay and AB Time are applied
following successful completion of the Hold Time.
Wait for TRS Inactive - once the weld parameters have been met, a 4 sec.
end-of-sequence timer is started, during which time the TRS input must
become inactive or an alarm will be generated.
Wait for ULS Active - During the 4 sec. end-of-sequence timer, the ULS input
must become active or an alarm will be generated.
Wait for START SWITCHES - During the 4 sec. end-of-sequence timer, the
START SWITCH inputs must be released or an alarm will be generated.
Ready State stores the current welding parameters into the NOVRAM.
One START SWITCH Pressed starts a 200 ms stagger time, during which
time the other START SWITCH must be pressed. If the second START
SWITCH is not pressed within 200 ms, an error will be generated and the
welder will return to the READY state.
SV Drive Active/Wait for ULS. If the ULS signal does not become inactive
within the 4 sec. timeout period, or a START SWITCH input is lost, the SV
drive circuits will be deactivated, and an error display will be generated.
ULS Inactive/Wait for TRS. If the ULS signal becomes inactive within the
4 sec. timout period, or the pretrigger source has become active within the
4 sec. pretrigger wait time, a 4 sec. timeout period will start.
If the TRS signal does not become active during its timeout period, the ULS
input becomes active, or one of the START SWITCH inputs is lost, the SV
drive circuits will be deactivated and an error display will be generated.
