TEST O/P A-H
•
For each of up to eight outputs, define when the output is active.
•
Options:
o
OFF : The output is not activated for this test.
o
ON : The output is active for the whole of the test
o
STANDBY : The output is only active whilst the test is selected but has not been
started. The output is deactivated when the test is started.
o
TEST : The output is only active once the test is started
FEEDBACK A-H
•
Define which feedback inputs are required before the test is allowed to run. The
feedback signals will typically be used to indicate correct positioning of the jig.
•
Each of up to eight possible inputs may be selected on (1) or off (0), e.g. to wait for
inputs A and C the setting will be “10100000”.
•
Feedback is checked after the test outputs A-H have been activated, but before the
vent output.
•
Note that the feedback inputs must be configured in the I/O Configuration menu.
FEEDBACK TIMEOUT
•
The default feedback timeout is set to 0.0 which disables the timeout function. The
instrument will display “Awaiting Feedback” until the correct feedback is applied or
the test is reset.
•
When the feedback inputs are not used for jigging they may be used to check signals
from test components. If the correct feedback is not supplied within the feedback
timeout period then the test ends with a FEEDBACK FAIL result.
EXTERNAL FAIL
•
Allows an external signal, for example a pressure switch, to be monitored. An
External Fail result is given if the signal is not in the expected state at the end of the
test time.
•
Note that the input function must be defined in the i/o configuration menu.
•
Options:
o
NO: External fail is not used for this test.
o
ON: The input is expected to be active at the end of the test time.
o
OFF: The input is expected to be inactive at the end of the test time.
o
CHANGE: The input is checked at standby and is expected to change state before
the test time ends.
