Table A-6 I/O Connector Pin Signals (Continued)
I/O Signal
O Level Active HIGH when the leak
detector is in ZEROING
mode.
Level Active HIGH when the leak
detector is in HOLD mode.
O Level Active HIGH when the leak
detector is VENT mode.
O Level Active HIGH when the leak
detector is in
START/ROUGH mode.
O Level Active HIGH when the leak
detector is in READY mode.
O Level Active HIGH when the leak
detector is in FINE TEST
mode.
O Level Active HIGH when the leak
rate is over set point #1.
O Level Active HIGH when the leak
rate is over set point #2.
O Level Active HIGH when the leak
rate is over set point #3.
Description
Performs the Zeroing
routine.
Performs a HOLD routine
and isolates the test port and
any test objects from the
leak detector vacuum
system.
Performs a VENT routine,
isolates the test port from the
leak detector vacuum system
and vents the test port to
atmosphere.
Performs a ROUGHING
routine on the test port and
any attached test objects.
Indicates that the leak
detector is completing a
STARTING routine and that
the filament and turbo are
OK.
Indicates that the leak
detector is ready for fine leak
testing.
Indicates that the value of
the leak rate exceeds the
value set in the 1REJECT
variable.
Indicates that the value of
the leak rate exceeds the
value set in the 2REJECT
variable.
Indicates that the value of
the leak rate exceeds the
value set in the 3REJECT
variable.
