• WELD
When welding, the relay output signal will start within 5 milliseconds after
the start of
SQUEEZE and will stay energized for 0 -
150 milliseconds
after the end of the
HOLD period.
• END OF WELD
When welding, the relay output signal will start 0 - 150 milliseconds after
the end of the
HOLD period and will stay energized for 350 -
450
milliseconds. If
another weld is initiated within this time, the
END OF
WELD
relay will be reset at the start of the next weld. The relay will still
close in the event of an aborted weld.
• ALARM
The relay output signal will start when the Power Supply senses certain
ALARM
conditions (with the exception of OUT OF LIMITS
alarms) and
will stay energized until the
ALARM state is cleared by pressing the
RUN
button (refer to
Appendix E, LCD Display Messages).
• OUT OF LIMITS
The relay will switch when the Power Supply senses any OUT OF LIMITS
c
ondition. It will start 0 - 150 milliseconds after the end of HOLD
and will
stay energized until the
OUT OF LIMITS
alarm state is cleared by pressing
the
RUN button, or at the start of the next weld (refer to
Appendix E, LCD
Display Messages
).
• P1 HIGH LIMIT
The relay signal will switch when the Power Supply senses that the Pulse 1
energy is higher than the programmed upper limit. It will start 0
-
150
milliseconds after the end of
HOLD and will stay energized until the
OUT
OF LIMITS
alarm state is cleared by pressing the RUN
button, or at the
start of the next weld (refer to
Appendix E, LCD Display Messages).
• P1 LOW LIMIT
The relay signal will switch when the Power Supply senses that the Pulse 1
energy is lower than the programmed lower limit.
It will start 0 -
150
milliseconds after the end of
HOLD and will stay energized until the
OUT
OF LIMITS
alarm state is cleared by pressing the RUN
button, or at the
start of the next weld (refer to
Appendix E, LCD Display Messages).
• P2 HIGH LIMIT
The relay signal will switch when the Power Supply senses that the Pulse 2
energy is higher than the programmed upper limit. It will start 0
-
150
milliseconds after the end of
HOLD and will stay energized until the
OUT
OF LIMITS
alarm state is cleared by pressing the RUN
button, or at the
start of the next weld (refer to
Appendix E, LCD Display Messages).
• P2 LOW LIMIT
The relay signal will switch when the Power Supply senses that the Pulse 2
energy is lower than the programmed lower limit. It will start 0
-
150
milliseconds after the end of
HOLD and will stay energized until the
OUT
OF LIMITS
alarm state is cleared by pressing the RUN
button, or at the
start of the next
weld (refer to Appendix E, LCD Display Messages).
