Pins 1 and 2 provide the PASS signal.
Pins 3 and 4 provide the FAIL signal.
Pins 5 and 6 provide the PROCESSING signal.
Pins 7 and 8 provide the RESET 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 (7) and pin (8)
while the reset function is activated. This is only a continuous closure dependent on
the length of time the reset button is held in an active state.
6.2. Remote Signal Inputs and Memory Access
The OMNIA 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 OMNIA 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
minimum pulse width or contact closure of 20mS
is required to guarantee a test start. A normally
open momentary switch can be wired across pins
2 and 5 to allow remote operation of the RESET
function. A minimum pulse width or contact
closure of 50mS is required to guarantee that a
running test will abort. 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
