3.8 : Buzzer :
On passing a harness a ringing buzzer sounds for @ 3 seconds. Buzzer’s tone and
volume can be controlled from presets at the back side.
Different tones can differentiate passed harnesses and to avoid confusion.
3.9 : Assembly :
Assembly will follow same steps as programmed. Tester will glow all tray LEDs from
which parts are to be picked up, in the first step. It also displays step number. At the same
time I/O LED corresponding to starting point say endA will glow and that of first endB will
blink. Hence parts from these trays will have to be picked up and then end A will have to be
inserted at location where LED glows. Other end/s of cable is to be inserted at endB i.e.
blinking LEDs. If it is inserted at proper location then first endB will stop blinking and next
endB LED will start blinking. At the same time all those LEDs will glow which are connected
by this net; even though the insertion is wrong. Hence identification of correct insertion is that
blinking LED stops blinking. This will continue till all I/Os in that step are connected
properly. Else display will show errors like open and short and LEDs will not stop glowing.
Once all steps are correctly assembled, tester will display pass.
Assembly : If start point is entered as ‘00’, tester will function as normal HAA without
pull test.
If start point is entered as ‘xx’, at point xx tester displays ‘FORCE < 900 xx’ i.e. pull is
less than 900 for point xx. Once switch A is on, display will be ‘FORCE >> 900’ i.e. first
switch is found OK. tester continues to check switch D for programmed time from 1second to
8 seconds. If switch D is found open, i.e. correct condition, tester starts buzzer. Buzzer will
stop after pulling is stopped and switch A is open again. If switch D is ‘on’ during this
programmed time, tester displays ‘FORCE>1200 FAIL’ and after @ 2 seconds ‘REMOVE
ASSEMBLY’.
Now
tester
is
in
continuous
checking
mode.
