Pins 7 and 9 provide the START OUT signal.
The following describes how the relays operate for each test condition.
PROCESSING
- The relay contact closes the connection between pin (5) and pin (6) 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 (1) and pin (2) 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 (3) and pin (4) after
detecting that the item under test failed. The connection will open when
the next test is initiated or the reset function activated.
RESET OUT
- The relay contact closes the connection between pin (8) and pin (7) while
the RESET bottom is pressed.
START OUT
- The relay contact closes the connection between pin (9) and pin (7) while
the TEST bottom is pressed.
6.1.2 Signal Inputs of Remote I/O and Programmed Test Files
The 7630 remote connector enables remote operation of the TEST, RESET and REMOTE
INTERLOCK functions, and allows the operator to select one of 10 pre-programmed test files.
When the PLC Remote mode is on, the 7630 will respond to simple switch or relay contacts
closures. A normally open momentary switch can be wired across pins 3 and 5 to allow
remote operation of the TEST function. A normally open momentary switch can be wired
across pins 2 and 5 to allow remote operation of the RESET function. When the PLC remote
function is (ON) the TEST switch on the front panel will be disabled to prevent a test from
being activated through this switch. 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.
The Remote File Select function gives the user the capability to quickly change parameters
and initiate a test remotely. Ten pre-programmed test files can be accessed by connecting
