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, 8, and 9 are blank.
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.
6.2. Signal Inputs of Remote I/O and Memory
The HypotMAX 7700 or HypotMAX 7704 remote connector enables remote operation of
the TEST, RESET, and Remote Interlock functions and allows the operator to select one
of three pre-programmed tests. When the 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.
The HypotMAX 7700 or HypotMAX 7704 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 HypotMAX 7700 or
HypotMAX 7704 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.
