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 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 (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.
7.2. Signal Inputs of Remote I/O and Memory Access
The Hypot III remote connector enables remote operation of the TEST, RESET, and
REMOTE INTERLOCK functions, and allows the operator to select Memory 1, Memory
2, and Memory 3.
When the PLC Remote mode is on, the Hypot III 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 Hypot III also allow access to three MEMORY PROGRAMS through the remote
control connector. This gives the user the capability to quickly change parameters and
initiate a test remotely. The Hypot III basically operates in a PLC mode by responding to
simple switch or relay contact closures. The built in memory programs of the instrument
are used to accomplish this. Three internal memory programs can be accessed, by
connecting terminals 7, 8, and 9 in different combinations.
