Emerson 2000IW Maintenance Manual page 42

Downspeed: The rate of speed of the actuator from the home position to the part.
General Alarm: An alarm that occurs due to a system fault and/or tripping a limit.
Ground Detect Mode: IW only, In this mode of operation, ultrasonics are terminated
after detection of a ground condition between the horn and fixture or anvil.
Horn Down: A mode in which ultrasonics are locked out and the user can advance the
Actuator for setup and alignment.
Linear Encoder: Provides carriage distance measurement during the welder cycle. IW+
only.
Pretrigger: The setting that causes ultrasonics to start before contact with the part.
Ready Position: State in which the welder is retracted and ready to receive the start
signal.
Required: State used with limits indicating that a reset will be required when the limit is
exceeded. The reset is accomplished by using the reset key on the front of the Integrated
Welder, or by external reset at the User I/O.
Reset Required: State used with alarms indicating that a reset will be required before a
cycle can be run. The reset is accomplished by using the reset key on the front of the
Integrated Welder, or by external reset at the User I/O.
Scrub Time: The amount of time after detection of a ground condition (option IW only) to
the termination of ultrasonics.
Seek: A setting where ultrasonics are on at 5% amplitude for the purpose of finding the
resonant frequency of the stack.
Stack: Converter, Booster, and Horn.
Test Scale: The magnification of the power bar scale on the front panel while the Test key
is pushed.
Time Mode: Terminates the ultrasonics at a user-specified time. Note: In Collapse or
Absolute Distance Modes the weld time parameter acts as an overriding condition. Ensure
Time is setup to allow for the collapse or absolute distances to be attained during a weld.
Timeout: A time at which the ultrasonic energy terminates if the main control parameter
has not been reached.
Trigger Beeper: An audible signal sounded when the trigger is made.
Upper limit switch (uls): A switch when activated indicates the actuator is in the home
position.
User-defined limits: IW+ only, for process resultants, where – is the user-defined lower
limit, and + is the user defined upper limit:
–/+ Time: The weld time reached during the weld.
-/+ Abs D: The absolute distance from the Home position reached during the weld.
–/+ Col D: The collapse distance reached during the weld.
Weld Time: The time for which ultrasonics are on.
