WELD SENTRY 2 Page 17
BASIC SETUP - SET END OF PROCESS
When the weld pulses are separated by an "OFF" time they could be part of the same weld process, for
example, a quench-temper weld function, or they could be two separate welds spaced close together.
Because the Weld Sentry cannot tell the difference, the "End of Process" screen is used to manually confirm
or reset the duration of the weld before proceeding through Basic Setup. This step is used only to set the
duration of the weld process, not to setup measurement time. Note: The default setting for maximum
process duration is 1 second. It can be changed to either 2 seconds or 4 seconds to accommodate longer
weld processes. Before using Basic Setup, select System Menu/Options - Basic Setup Sample Weld Time.
(12) Press

to move the highlighted area and
change the end of process time displayed at the
top of the screen.
In the example at right, there are two separate
weld periods separated by an off period. One
period starts at 0ms and one starts at l000ms.
(13) Press the right arrow to move the highlighted area to the right and lengthen the process time. This
will include the second period in the Sentry monitoring schedule. Press the left arrow to move the
highlighted area to the left and shorten the process time. This will exclude the second period from
the schedule.
(14) Press [ENTER] when the highlighted area includes all periods in the weld schedule.
(15) The “Test Weld” screen shown at right will be
displayed.
(16a) Make
a test weld as instructed in step #(4) and
proceed with steps #5 - 10, or proceed to 16b.
(17a) The Sentry will automatically setup individual
weld periods when they are separated by "off"
time. Press [ 1 ], [ 2 ] or [ 3 ] to display the graphic screen for each period. The period number is
displayed on the screen as “PER 1”, “PER 2” and “PER 3”. Follow steps #5 - 10 to setup the
measurement times for each period screen.
(18a) Press [SAVE] when each the screen displays the desired measurement unit and time window.
BASIC SETUP - PERIOD DEFINITION
For most weld schedules this step will not be required and the Sentry can setup a monitoring schedule
automatically. However, if the sample weld consisted of more than 3 periods separated by "off" time or if
the total duration of the periods is longer than 500 milliseconds it may necessary to define the weld periods
to be monitored.
