125 VAC (0.5 ADC / 30 VDC). The signal outputs are provided on the 9 pin
female D-type connector. Below is a list that indicates what conditions activate
each pin. When a terminal becomes active the relay closes thereby allowing the
external voltage to operate an external device.
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.
6.2. Remote Signal Inputs 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
Location 1, 2, and 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 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
