REMOTE OPERATION
41
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.
11.3 Signal Inputs of Remote I/O and Memory Programs
The Line Leakage Tester remote connector enables remote operation of the TEST
and RESET functions or allows the operator to select one of three pre-
programmed tests. A signal input is also provided to indicate that a Withstand test
is processing. 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 Line Leakage Tester also allows 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 Line Leakage Tester
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 the user can select the correct memory
program.
ACTIVATING MEMORY PROGRAM FUNCTIONS THROUGH THE
REMOTE CONNECTOR, SELECTS THE PROGRAM AND STARTS
THE TEST WHICH IS PRE-PROGRAMMED INTO THAT MEMORY.
DO NOT CONNECT VOLTAGE OR CURRENT TO THE SIGNAL
INPUTS, THIS COULD RESULT IN DAMAGE TO THE
CONTROL CIRCUITRY.
MEMORY 1 - Momentarily connecting terminal 7 to 8 signals the instrument to
immediately begin the test program that is stored in memory 1.
MEMORY 2 - Momentarily connecting terminal 7 to 9 signals the instrument to
immediately begin the test program that is stored in memory 2.
MEMORY 3 - Momentarily connecting terminal 7 to terminals 8 and 9 signals the
instrument to immediately begin the test program that is stored in memory 3.
