OPERATION
The following describes how the relays operate for each test condition.
PROCESSING - The relay contact closes the connection between pin (1) and pin (4)
while the instrument is performing a test. The connection is opened at the end of the test.
PASS - The relay contact closes the connection between pin (6) and pin (7) after
detecting that the item under test passed all tests. The connection is opened when the
next test is initiated or the reset function is activated.
FAIL - The relay contact closes the connection between pin (8) and pin (9) after detecting
that the item under test failed any test. The connection is opened when the next test is
initiated or the reset function activated.
2. SIGNAL INPUTS OF REMOTE I/O
The 2900 family of Hipots remote connector enables remote operation of the TEST
and RESET functions. A normally open momentary switch can then be wired across
pins 3 and 5 to allow remote operation of the TEST function. A normally open
momentary switch can also be wired across pins 2 and 5 which allows remote
operation of the RESET function. For safety, the front panel RESET switch remains
active even when a remote reset switch is connected so that high voltage can be shut
down from either location.
DO NOT CONNECT VOLTAGE OR CURRENT TO THE SIGNAL
INPUTS, THIS COULD RESULT IN DAMAGE TO THE CONTROL
CIRCUITRY.
