Signal line
name
I/O Function
READY
―――――――
OUT
LOW level in the READY state
L-FAIL
―――――――
OUT
LOW level in the FAIL state at LOWER (minimum value)
U-FAIL
―――――――
OUT
LOW level in the FAIL state at UPPER (maximum value)
PASS
――――――
OUT
LOW level in the PASS state
TEST
――――――
OUT
LOW level in the TEST state
H.V.ON
――――――――
OUT
LOW level when a voltage is generated in the output terminal
EXT-E
―――――――
IN
At LOW level, the external I/O input signal is active.
INT.LOCK
―――――――――――――
or
STOP
―――――――
remains active regardless of this signal.
START
―――――――
IN
LOW level is equivalent to pressing the unit
START
key and
provides the same functions.
STOP
――――――
IN
LOW level is equivalent to pressing the unit
STOP
key and
provides the same functions. This signal is valid regardless
of
EXT-E
――――――――
status.
INT.LOCK
―――――――――――
IN
Inter-lock function terminal.
This signal is always active regardless of the status of the
EXT-E
――――――――
terminal.
When connected to ISO.GND, this terminal cancels the Inter-
lock function, enabling the unit to function properly. When
disconnected, the terminal disables all keys.
To activate the Inter-lock function, set the optional Inter-lock
function to "
1
:Set."
Use this terminal for a protective device against electric
shock that uses an area sensor or the like. See Section 9.1.4.
W-MODE
――――――――――
OUT
LOW level when performing a withstand-voltage test in the
withstand-voltage test screen.
I-MODE
――――――――
OUT
LOW level when performing an insulation-resistance test in
the insulation-resistance test screen.
W-FAIL
――――――――
OUT
LOW level in FAIL state during a withstand-voltage test.
I-FAIL
――――――
OUT
LOW level in FAIL state during an insulation-resistance test.
STEP-END
―――――――――――
OUT
LOW level upon completion of one step in a program test.
FILE-END
――――――――――
OUT
LOW level upon completion of one file in a program test.
FILE-E
――――――――
IN
At LOW level, the file selection terminal (
FILE-0 to 4
―――――――――――――
)is
active.
FILE-0
～
4
――――――――――
IN
Program test-file selection terminal.
ISO.GND OUT
Outputs a GND, insulated from the internal GND for the
unit. Used to temporarily activate the external I/O function.
EXT.COM IN
Terminal common to each output terminal.
ISO.DCV OUT
Outputs a power voltage of 5 V (60 mA), isolated from the
internal power supply. Used to temporarily activate the
external I/O function.
EXT.DCV IN
Terminal for supplying power from the outside.
Input power-voltage range: DC 5 to 30 V
