2. Installation and Operation
■ Head Installation
①Fix the device using the holes on the fixture bracket and the screws supplied,
at a desired location.
※Please install the head in a shielded equipment.
②Install the head in a shielded location, the controller at a place with easy
access, and connect the power and ground cables.
③Connect the Head and the controller using the connection cable provided.

Page 7/ 23
■ Controller Operation Method
①Before turning on the controller power switch, please connect the head and
the controller using the connection cable.
②Turn on the power switch on the rear panel of the controller. (Red lamp will be
lighted on the switch)
③Power lamp will be turned on if the power is normally supplied.
④[Interlock input] By closing the DSUB I/O Connector pin 14 and 15 with
contact input on the rear panel of the controller, the ionizer is ready to be
irradiated. Check the interlock lamp status on the front panel of the controller.
(For the safety instructions, please refer to “1) Interlock Input Signal” on Page
11)

Page 8/ 23
⑤[Ionizer Irradiation ON] Push Run/Stop button on the front panel of the
controller once.
(For the Remote Ionizer Irradiation ON method, please refer to “2) Remote
Signal Input Contents” on Page 12)
During regular irradiation, the area around Run/Stop button will be lighted with
white light, and LCD will display hourglass symbol.
⑥[Ionizer Irradiation OFF] Push Run/Stop button on the front panel of the
controller once.
(For the Remote Ionizer Irradiation OFF method, please refer to “2) Remote
Signal Input Contents” on Page 12)
When the device turns off normally, the light around Run/Stop button will turn
off and the hourglass symbol will disappear.

Page 9/ 23
■ Controller Operation Status when Head FAIL Occurs
Due to the abnormal operation of the head, the head red light will be lighted, and the
Head Fail red light will be illuminated on the controller. The lamp for the failed head will
be turned on.
The LCD will display “Err” test additionally.
■ Controller Time Reset Method
The VSC-104Z controller calculates the cumulative irradiation time automatically
and displays it on the LCD window in hours (The accumulation time of the
controller irradiation operation, not the time linked with the head). Based on this,
the replacement time of the head can be measured. Since the initialization is
necessary after replacing the head, the controller time can be reset as follows.
①When the controller calculates the usage time of 10,000 hours, the head
indicator lamp 1, 2, 3 and 4 flash.
(Even if the replacement cycle comes, the head will operate normally if it is
not HeadFail.)
②Press the Time Reset switch on the controller once to confirm that the time
on the LifeTime LCD is reset to 0 hours.

1) Interlock Input Signal
a) Interlock ON
When the interlock contact connected to D-SUB 14 & 15 are closed, it is ready to
irradiate soft X-ray. The Interlock on the front panel of the controller will be lighted.
b) Interlock off
When the interlock contact connected to D-SUB 14 & 15 are opened, Run/Stop
switch and the remote do not work. The interlock on the front panel of the
controller will be turned off.
※Warning: If humans are exposed directly to soft X-ray, it could cause damages. Therefore, the
interlock must be connected. If the enclosure door is opened during the irradiation of soft X-ray, the
interlock terminal will open, and the irradiation of soft X-ray will automatically stop. If the enclosure
door is closed, the interlock will close, and the device will be in the ready status.
- Safety Features
If the interlock door becomes “open” status during the irradiation of soft X-ray (“Run/Stop” button is lit
on the front panel of the controller), the irradiation will stop.
“Interlock” lamp and “Run/Stop” switch are turned off on the front panel of the controller.
If the interlock is closed (safe status), the device will return to the safe mode and can start irradiation
of soft X-ray by inputting the Remote On signal into the controller.

2) Remote Input Signal
Remotely control the photo ionizer by inputting the control signal from the external
(equipment side) to the D-Sub 15pin connector.
- Control Mode 1 : D-SUB 9 & 10 Contact Open
- Control Mode 2 : D-SUB 9 & 10 Contact Close
a) Control Mode 1
①Remote On
Only irradiates soft X-ray when D-Sub15pin 11 & 13 terminals are closed.
②Remote OFF
Does not irradiate soft X-ray when D-Sub15pin 11 & 13 switches are open.

Page 13 / 23
b) Control Mode 2
①Remote On
Irradiates soft X-ray when D-Sub15pin 11 & 13 terminals are closed for more
than 50ms.
②Remote OFF
Does not irradiate when D-Sub15pin 12 & 13 terminals are closed for more
than 50ms.

Remote Operation Procedure
①Confirm that the head is installed in the shielded facility and the door with Interlock capability
is closed.
②Turn on the controller's power switch.
※The lamp on the front of the controller lights up for about one second.
③If the Interlock is closed, the INTERLOCL lamp will be turned on.
※Check whether interlocking operation (opening / closing) works normally.
④Start the operation by the remote procedure.
Initiates irradiation when the Remote On signal is inputted to the device
Mode 1 (momentary) by remote control:
Remote on (Dsub 11-13) close at the initial moment of irradiation.
Remote on (Dsub 11-13) close during the desired irradiation ON period.
Remote OFF (Dsub 11-13) open to stop irradiation
Mode 2 (alternate) by remote control:
Remote on (Dsub 11-13) close at the initial moment of irradiation.
Remote OFF (Dsub 12-13) close to stop irradiation

■ Signal Input / Output Operation Examples
1) Example of using LED output drive and relay input
※Since the output side current uses a maximum 20mA output, it is necessary to
drive the external LED, photo coupler, and TTL semiconductor and use the
protection resistance after checking the driving current.
※If power is supplied, the internal components of terminal 9, 11, 12 and 15 on the
input side can be damaged

Input side (must use switch contact)
GND
Unused
※Parts may be damaged if external power
is applied to the input side.

2) Example of using TTL output drive and semiconductor contact input
※Since the output side current uses a maximum 20mA output, it is necessary to
drive the external LED, photo coupler, and TTL semiconductor and use the
protection resistance after checking the driving current.
3) Example of Photocoupler Input / Output usage
※Since the output side current uses a maximum 20mA output, it is necessary to
drive the external LED, photo coupler, and TTL semiconductor and use the
protection resistance after checking the driving current.

3. Safety Instructions
Head that emits soft X-ray during operation must be shielded for users’ safety. Since
the shielding rate differs depending on the material, please refer to the following
materials to design the shield.
● Point A: Shielding 10cm from the front of the X-ray window
Shielding Material
Thickness [mm]
Stainless steel
0.2
Aluminum
3
glass
5
PVC
4
Acrylic
46
▣The above shield thickness design is only suitable when the shield is 10cm away from
the source of the X-ray. If the distance is shorter, the thickness must be increased.
▣After shielding, the leaked radiation level must be lower than the legal limit (10μSv/h).

Page 19 / 23
4. Decay Time
Static electricity removal performance is represented by the time taken to drop the
metal plate charged at ±1000V to ±100V by irradiating soft X-ray.
※Decay Time (when mounted): Top -> Down Irradiation, Based on straight line
distance.
