CHAPTER 3: SYSTEM CONFIGURATION
HF-2500A HIGH FREQUENCY WELD CONTROL
990-371 3-15
Section III. Operational States
The Power Supply has seven operational states:
NO WELD WELD MENU MONITOR
TEST ALARM RUN
You go to the
NO WELD
,
MENU
,
TEST
,
RUN
and
MONITOR
states through the control panel. The
WELD
and
ALARM
states are functions of the force firing switch and foot switch input states.
No Weld State
Setting the
WELD/NO WELD
switch on the control panel to the
NO WELD
position inhibits the delivery of
weld energy if a weld is initiated, and will display a
WELD SWITCH IN NO WELD POSITION
alarm on the
screen. But the Power Supply will still go through its electronic weld cycles as programmed into the
selected weld schedule. Use the no weld state when adjusting the air regulators on air actuated weld heads.
Menu State
Pressing the
MENU
key puts the Power Supply in
the menu state. It brings up menu screens that
enable you to select various options common to
all weld schedules, such as how the Power Supply
interfaces with the force firing switch, foot switch
and weld head.

Test State
Programming a schedule for a voltage feedback
welding mode, or changing the voltage or time
settings while in the voltage feedback welding
mode, puts the Power Supply in the
TEST
state.
After making one weld, the Power Supply
internally optimizes the feedback control loop to
produce the fastest rise time, minimum overshoot
weld pulse. The
TEST
state is automatically
replaced by the run state for subsequent welds.
