The Alarm screen displays information about the alarm(s) that have been

triggered by the system encountering parameters outside of the specified

tolerance limits. The screen will indicate whether alarms occurred in Time,

Distance or Energy. If there are no alarms, dashes will display. If there are

alarms, an L (for Low limit, indicating that the low limit was violated) and/or

an H (for High limit, indicating that the high limit was violated) will display by

the applicable mode (time, distance or energy). When a new cycle begins,

the system will automatically clear the current alarm.

Counter Screen

The Counter screen displays information about the job number, the number

of cycles run to date, the customer resettable counter (CRC) and the

resettable alarm counter (RAC). The 2 resettable counters can be reset

whenever desired by pressing the Clear key when the counter screen is

displayed. (The keypad must be unlocked.)

RELATIONSHIP OF TIME, DISTANCE AND ENERGY
SETTINGS

Parameters can be set in the time, distance and/or energy menus. The

settings in all of these menus should be taken into account when you are

setting up a job since they do not function independently of each other and

a parameter in one menu can impact the effect of a parameter in another

menu.

For example, if you specify a weld time of 2 seconds, an energy setting of

2,000 joules, and clear any previous distance settings (so that only dashes

appear in the distance menu settings), the weld cycle will be terminated by

whichever of the 2 settings (Weld Time or Energy Setting) is reached first –

that is, either when ultrasonics have been applied for 2 seconds or when

energy equivalent to 2,000 joules has been delivered to the parts being

assembled. If 2 seconds is reached before 2,000 joules have been delivered,

the weld cycle will terminate regardless of the amount of energy delivered,

and vice versa.

The start-up ready screen which shows the last weld information will show a

flashing “sec” or “J” to indicate which setting was achieved first and thereby

terminated the weld cycle.

In the example above, if the weld time of 2

seconds is reached before 2000 joules have been delivered, the ready screen
