DID YOU KNOW?
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.
Pins 7 and 9 provide the START OUT signal.
The following describes how the relays operate for each test condition:
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.
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.
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.
START OUT
– The relay contact closes the connection between pin (7) and pin (9)
after a test sequence has completed and passed. This is a momentary relay closure
and may be used to initiate a Hipot or Ground Bond test from another Associated
Research, Inc. instrument.
6.2. Remote Signal Inputs and Memory Access
The 620L 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 620L 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
