OPERATION
34
Pins 1 and 2 provide the PASS signal.
Pins 3 and 4 provide the FAIL signal.
Pins 5 and 6 provide the PROCESSING 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 any test. The connection is opened when
the next test is initiated, or the reset function activated.
4.2. Signal Inputs on Remote I/O
The HYPOT II remote connector enables remote operation of the TEST, RESET
and REMOTE INTERLOCK 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 the test switch. A normally open momentary switch can then be
wired across pins 3 and 5 to allow remote operation of the TEST function. A
normally open momentary switch can also be wired across pins 2 and 5 which
allows remote operation of the RESET function. 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.
Remote Interlock is a feature that inverts the present reset logic on the instrument
from normally opened (must close contacts to activate the reset) to normally
closed (must open contacts to activate the reset). Hardware and software have
been configured to provide the interlock connections on pins 4 and 5 of the
Remote Interface, Signal Input port. This reset scheme is designed for use with an
external safety interlock device that utilizes a “Fail-When-Open” configuration on
its output interface. The instrument can still be used without the external reset
device as long as the Interlock Connector (provided with unit) is plugged into the
Remote Interface, Signal Input port. If there is nothing connected to the Remote
Interface, Signal Input port to provide a connection to the interlock (reset), then
the instrument will not function.
