tester. These are normally open free contacts and will not provide any voltage or
current. The ratings of the contacts are 1 AAC / 125 VAC (0.5 ADC / 30 VDC). The
signal outputs are provided on the 9-pin female D connector. Below is a listing 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.
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. The process contact is closed all the way through to the end of the discharge
cycle in DC units.
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.
6.2. Signal Inputs of Remote I/O and Memory Access
The HypotMAX 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 HypotMAX 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
remains active even when a remote reset switch
is connected so that high voltage can be shut
down from either location.
