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 Remote Signal Inputs and Memory Access
The SE remote connector enables remote operation of the TEST, RESET, and REMOTE INTERLOCK
functions, and allows the operator to select one of 10 pre-programmed test files.
When the PLC Remote mode is on, the SE 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.
The Remote File Select function gives the user the capability to quickly change parameters and
initiate a test remotely. Ten pre-programmed test files can be accessed by connecting pins 1, 6, 8
and 9 to the common pin 7, in different combinations. The memory select bits should be set
simultaneously and remain set for a minimum of 20ms to guarantee that the correct memory will
be selected. However, the memory select bits may be set in sequential manner, provided that the
time delay between each bit is less than 4ms. When the desired bit pattern has been established it
should remain set for a minimum of 20ms to guarantee that the correct memory will be selected.
The Remote File Select Truth Table (binary) shows the different combinations of momentary
switch (relay) closures, and which memory programs that will be selected as the result. It may be
necessary to "OR" the momentary switches (relay contacts) to prevent incorrect program selection
due to timing errors.
