Signals on Remote I/O
REMOTE INPUT/OUTPUT
Remote Output
The rear panel connector provides three output signals to remotely monitor PASS, FAIL,
and PROCESSING conditions. The monitoring signals are provided by three normally open
internal relays that toggle ON and OFF to indicate the condition of the instrument. These
are normally open free contacts and will not provide any voltage or current.
Output Signal
Pins
Description
PASS
1 and 2
The relay contact closes after detecting that the device under test passed all tests. The
connection is opened when the next test is initiated or the reset function is activated.
FAIL
3 and 4
The relay contact closes after detecting that the device under test failed any test. The connection
is opened when the next test is initiated or the reset function activated.
PROCESSING
5 and 6
The relay contact closes while the tester is performing a test. The connection is opened at the
end of the test.
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). When a terminal becomes active, the relay closes thereby allowing the external voltage to operate an
external device.
Remote Input
The HYAMP remote connector enables remote operation of the TEST, RESET, and
REMOTE INTERLOCK functions, and allows you to select one of 10 pre-programmed test
files.
Output Signal
Pins
Description
TEST
3 and 5
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.
RESET
2 and 5
A normally open momentary switch can be wired across pins 2 and 5 to allow remote operation
of the RESET function. For safety, the front panel RESET button remains active even when a
remote reset switch is connected so that high voltage can be shut down from either location. A
minimum pulse width or contact closure of 50mS is required to guarantee that a running test will
abort.
INTERLOCK
4 and 5
Remote Interlock utilizes a set of closed contacts to enable the tester’s output. The output of the
tester will be disabled under the following conditions:
• If the Interlock contacts are open and the TEST button is pushed
• If the interlock contacts are opened during a test (test will automatically abort)
A pop-up message will be
displayed on the screen:
The tester can still be used without the external interlock device as long as the Interlock Connec-
tor (P/N # 38075 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, the tester will not perform tests.
When the PLC Remote mode is ON, the tester will respond to simple switch or relay contacts closures. When the PLC Remote
function is ON the TEST button on the front panel will be disabled.
