WELD SENTRY 2
(16b) When the "Test Weld" screen is displayed do not make another weld, instead, press the period on the
keypad. The "Period Definition" screen shown below will be displayed.
(17b) Press [ 1 ], [ 2 ] or [ 3 ] to highlight and select
either the first weld period, the second weld
period or the third weld period. In the example,
the first period is selected and "Period 1” is
displayed at top of screen.
(18b) Press [CHNG] to display the period "Start',
"Stop" and "End" time at top of screen and to
select the flashing arrows under the highlighted
period.
Note: The time between period "start" and period “stop” is the "acquisition' time for the period. The
maximum total acquisition time for all 3 periods is 500 milliseconds. The time between period
“stop” and period “end” is used to “filter” out noise and prevent re-triggering or false triggering, it is
not included in the acquisition time and does not count against the 500 millisecond.
(19) Press

to move the
↑
arrow which is flashing and change the period start, stop or end times. This
does not set the actual measurement window, which is done in another step, however, it does set the
maximum measurement times. When the measurement window is set, it can be no longer than the
acquisition period.
Example, Weld Schedule longer than 500 ms (30 cycles): To measure the first 500ms, set "start"
time at 0ms, stop time at 500ms and end time past the end of the weld cycles. If any weld cycles
occur after "end" time, the Sentry will re-trigger. To measure the last 500ms, set "start" time 500ms
before the end of the weld, "stop" time at the end of the weld. “End” time should be set at a time
after the electrodes have lifted from the part to prevent any re-triggering.
(20) After the monitoring periods have been defined, press [ENTER] to accept the configuration. The
Test Weld Screen will be displayed.
(21) Make a Test Weld as instructed in step #15. Setup the Measurement times and SAVE the Sentry
Schedule.
CHANGING SENTRY PROGRAMS A-E
Each Sentry schedule may be setup to consist of up to 5 individual programs, A - E. For example,
Schedule 001 could be setup to consist of Program 00lA, Program 00lB, Program 00lC, Program
001D and Program 001E. Each program can be setup to monitor any combination of weld periods,
weld windows or measurement units.
MONITOR MULTIPLE MEASUREMENT UNITS
(1)
First, setup and save a monitoring schedule using Basic Setup.
(2)
In the Run state, press [PROG] twice to display the Sentry Program screen as shown below.
(3)
Use the arrow keys and move the cursor to the right of Program 001A to END.
