POWER ON PROCEDURE Connection to external equipment
STOP
Stop signal for leak testing.
Rising pulse signal greater than 200msec
START
Start signal for leak testing.
Rising pulse signal greater than 200msec.
FITTING
Start signal for fitting testing.
Rising pulse signal greater than 200msec
Operates in ready status.
BUBL
Only pressurizes the leak test circuit.
Rising pulse signal
Progresses to Exhaust when the signal is turned OFF
Operates in ready status.
RETRY
Re-outputs data from the RS-232C.
Operates in ready status.
GROUP
Selects the GROUP which will be tested.
4 signals out of Group Numbers 1~8 will be input as
binary digits.
CAL
If the CAL signal is input while testing (mastering) is
being conducted, it will be executed while the calibration
port is being ventilated.
Psw
External pressure switch input signals
・
Mount a pressure switch to confirm the Open/Close status of the work port stop valve.
To prevent a potential problem, configure the wiring to input the ON signal when the valve is closed.
・
ERR 002 will be displayed on the LCD if it senses the valve is closed.
ENG
External Pressure Value Input Signal
・
Connect a valve with a pressure sensor to the work port and configure the wiring. If the supplied pressure does not
reach the tester’s specified test pressure, it will send out a P. NG error to prevent a potential problem.
・
The detection timing is same as with Psw.
LM1
LM2
Cylinder Clamp Position Input Signal
・
When a clamp cylinder is controlled by this unit,
this signal can be utilized to detect the Up/Down
alignment position of the clamp cylinder.
IN
+COM
-COM
Floating Circuit Power Input
・
Each REMOTE input terminal employs a floating circuit to
avoid interference from external peripheral
equipment. Therefore, if power is not supplied to this terminal,
the signals that are input to the REMOTE terminals cannot be detected.
・
If this unit is being controlled using PLC, supply the power
to this terminal from the connected equipment using the specifications
listed below.
OK
+NG
-NG
2NG
B.NG
P.NG
The Leak test judgment is output.
This Judgment is
output during the EXH process.
The test result signal will be output.
RUN Output during operation. (Test/Fitting/ BUBL testing etc.)
RDY Output during the Ready Status. (When operation can be accepted)
END
Output at the end of operation.
・
Outputs upon the completion of testing.
・
Read the detection results at this time.
ERR
This error signal is output when the tester is in error mode.
ERR will be indicated by code number on the display.
(See ERR reference chart on page 109~110)
M/R
Outputs from MANUAL/REMOTE
・
Outputs on remote movement.
OUT
DC+24V
DC+24V is output
・
If you desire a hand switch for START/STOP
operation, but it is difficult to supply an external power source, (When using the manual switch)
it is possible to supply power to the floating
circuit by using a wiring scheme as described on the right.
Outputs signal at the start
of the exhaust
progress
Connect DC+24V to +COM
Connect GND to –COM
Input at least 200msec before inputting
the START (MASTER) signal
Input at least 200msec before inputting
the START (MASTER) signal
Greater than 200 msec
Con24V to +COM
Configure 0V to –COM
Greater than 200 msec
Greater than 200 msec
The maintenance label signifies
continued pressure maintenance
Greater than 200 msec
LM1: The clamp cylinder is clamped
LM2: The clamp cylinder is unclamped
