PRINTER OPERATION
If a printer is to be used for documentation of the dynamic process conditions,
it must have an RS232 serial port interface, a buffer of 2K bytes and be
capable of accepting a transmission rate of 4800 Baud. Following completion
of an assembly cycle, the assembly number, percentage of maximum power
used, energy level, weld cycle duration and reject status can be printed.
When the number of welds or number of rejects is displayed on the LCD, as
a result of pressing the INFO key the requisite number of times, that same
information can be printed.
The green LED in the upper corner of the PRT key must be illuminated for a
printout of process conditions to occur. Press the PRT key to obtain a printout.
Refer to the printer displays shown on the next pages for examples.
PRINTOUT OF THE WELD ENERGY CURVE
A graphic display of the actual weld curve can also be printed out if a printer
with a serial port interface and a buffer of 2K bytes, such as an Epson Model
LX-810 or comparable, unit is used.
The printout of the weld curve plots the actual pattern of instantaneous
loading as a function of time. The vertical line at the beginning of the printout
indicates the idle losses of the converter, booster and horn in air; and the area
under the curve corresponds to the energy delivered throughout the cycle.
(Refer to the sample printer displays on the next page for examples.)
The printout of the weld curve is initiated by pressing the ENTER key for
approximately 1 second until an audible alarm sounds and the following
message appears on the LCD screen:
The printout requires approximately 70 seconds to complete, with a Baud rate
of 4800.

NOTE: Use of a
printer causes the
cycle to be extended
by approximately
200 ms.
