Avoid the Risk of Fire!
Every time your wire line stops, be sure that the HV in the electrode goes off. If
the HV remains ON while your wire line is stationary, the wire insulation within
the electrode will heat and there is a danger of combustion. Refer to the table in
“Installation” labelled “Terminal Block connections,” under HV Enable on how to
safely install your spark tester.
Caution: Pacemaker Warning
Clinton Instrument Company strongly advises any individual using a pacemaker
or other such medical device to avoid operating or being in the vicinity of spark
testers. Current studies indicate that such medical devices can malfunction in the
presence of electrical and magnetic fields. When a fault occurs in the electrode
of a Clinton spark tester, both high and low frequency electromagnetic fields are
generated. The strengths of these emissions are unknown, since they depend on
test voltage and other variables. The danger is greater when a customer does not
ground the inner conductors of a test product. While Clinton cautions its cus-
tomers to ground the test product for safety reasons, many times this warning is
ignored. In this situation, both the spark tester and the entire length of the wire
line will radiate these emissions. There is also a serious risk of electrical shock if
an individual comes into contact with an ungrounded test product.

Electrical Shock Hazard from Production Line Spark Testers
By Henry H. Clinton
The commonly accepted maximum values of 60Hz. current passing through the
human adult body which permit a subject to let go of electrodes are nine
milliamperes for males and six milliamperes for females. At 3000 Hz. this value
increases to about 22 milliamperes for men and 15 milliamperes for women, DC
currents do not present the same let-go problems, but a subject can readily let go
at a level of 60 milliamperes. A continuous 60 Hz. current above 18 milliamperes
stops breathing for the duration of the shock only. Ventricular fibrillation may
occur above a level of 67 milliamperes. The reaction current level of 60 Hz. is
about .5 milliamperes. Above this level a muscular reaction can occur which can
cause a secondary accident. The DC and 3 kHz. Levels are probably considerably
higher. Capacitor discharge energy of 50 Joules (watt-seconds) is regarded as
hazardous.
Clinton DC spark testers are current limited to 5 milliamperes or less. Three
kilohertz spark testers are limited to 4 milliamperes or less, and 60 Hz. types to 7
milliamperes. Impulse spark testers can deliver a maximum charge of about .2
Joules 248 times per second. All these spark testers have current outputs above
the reaction level, but none above the let-go threshold level. Because of the
possibility of secondary accidents caused by muscular reactions, operators should
be protected against accidental shock. Electrodes are supplied with interlock
switches, and these should not be disabled. The conductor under test should be
grounded. If an operator must inspect the product by touching its surface while
it is being spark tested, he should be electrically insulated from his environment,
and any possible cause of a secondary accident caused by reaction should be
eliminated.
For references, see: Dalziel, Ogden, Abbot, “Effect of Frequency on Let-Go
Currents,” Transactions of A.I.E.E., Volume 62, December 1943, and Dalziel,
“Electric Shock Hazard,” I.E.E.E., Spectrum, February 1972.

IT-30B Instruction Manual –Page 12
Site Preparation
Select a suitable location for the spark tester:
The IT-30B Spark Tester is designed for use in a fixed location, permanently
connected to its power source. The unit may be mounted on a table or on a
Clinton floor stand and should be placed at wire line height and within easy reach
of the operator. For detailed dimensions of the spark tester, please see the
specification sheet.
The spark tester should be adjusted so that the product runs centered in the
electrode in both the vertical and horizontal axes and parallel to the mounting
plate. Vertical and horizontal dimensions for wire centers for standard electrodes
can be found on drawings supplied with this manual. For non-standard
electrodes, or for copies of the required drawings, contact the Engineering
Department of The Clinton Instrument Company.
When the spark tester is to be placed on a primary or jacketing (sheathing)
extrusion line, it is desirable to locate the equipment as close to the extruder
cross-head as practical, this generally means locating it just after the water
cooling trough. In this case it is important to wipe the water off of the product
thoroughly before it enters the spark tester electrode containment. Failure to
adequately dry the surface of the wire or cable can cause false-counting, and can
cause premature failure of the equipment.
To mount the unit on a horizontal surface:
With a screwdriver, remove the (4) plastic feet from the tapped inserts in the
bottom of the spark tester chassis. Insert (4) M-6 screws through the mounting
surface into the (4) tapped inserts. Be sure the screws do not extend into the
chassis more than 1/2 inch (12mm).
To install the unit on a Clinton floor stand:
Assemble the floor stand as shown in the drawings at the back of this manual.
Secure the tripod base of the floor stand to the shop floor using 1/2” (12mm)
bolts and washers. Remove the (4) plastic feet from the tapped inserts on the
bottom of the spark tester chassis, as shown above. Mount the spark tester to
the stand by feeding (4) M-6 screws supplied with the floor stand through the
bottom of the floor stand plate and into the (4) tapped inserts in the bottom of
the spark tester.

Model IT-30B Impulse Spark Testers
IT-30B Instruction Manual –Page 13
To install RC Display onto the IT-30B
With a screwdriver, remove the 2 Screws on the top of the IT-30B. Align the 2
mounting holes on the RC display mounting bracket with the holes on the top
of the IT-30B. Secure the bracket with the 2 screws that were removed.
Once the display is secure to the top of the unit Connect the 9-pin Serial port
on the rear of the RC display to the 9-pin “DISPLAY” port on the rear of the IT-
30B spark tester using the supplied 1 foot long serial cable.
The RC display can be mounted remotely up to 200 feet away using an
optional serial cable. See Optional Accessories for part numbers.
Provide for ventilation of the Test Module
As with any apparatus producing a spark or electrical corona, the IT-30B Spark
Tester produces ozone in the electrode region. While ozone reverts harmlessly to
oxygen within a few minutes, an external air extraction system is recommended
and should operate whenever the spark tester is in use. The exhaust of the
external air extraction system should be discharged either outdoors or into some
area well away from workers.
Power Wiring
Caution
The RCW is intended to be powered from a power cord containing 18ga or larger
conductors with a ground wire. Reference included Clinton Instrument Co. part number
03780.
Mains Power
Note that the spark tester has a self-adjusting power supply with an operating
voltage range of 100V to 240V at 47-63 Hz. 240VA Maximum (Overvoltage
Category II)
Maximum acceptable mains voltage fluctuation +/-10%
Ground the Spark Tester
Locate the ground stud on the back panel of the spark tester. Remove the outer
nut and crimp terminal. Crimp a 16 awg. (1, 29 mm2 , 1, 31 cross section) stranded
insulated wire (preferably green with a yellow stripe) to the crimp terminal.
Fasten this to the ground stud and secure with the keps nut. Connect the other
end to a safety ground system in accordance with EN 60204-1:1993, Section 5.2,
Table 1.

Terminal Block Wiring
Refer to the following table for information on pin functions. Locate the green
terminal blocks on the back of the spark tester and its companion green terminal
block connectors that came with the unit.
Relay Circuits rated for maximum 120V at 2amp, 240V at 1 Amp. (Overvoltage
Category II)
Conductors connecting auxiliary equipment, relays and switches should be
shielded 22 gauge or larger with double or reinforced insulation. The wires should
be stripped back ¼” (6mm) and fed into the green terminal block connector at
the proper pin number. Shields from conductors connecting auxiliary equipment
should be grounded to the safety ground terminal.

Connecting the Serial RS485
The model IT-30B is equipped with an RS-485 serial interface allowing the spark
tester to receive commands and exchange information with a PLC or computer.
Programming and control of voltage settings, which can be done manually on the
IT-30B display, can also be done through this interface. Control display buttons
can be disabled when the serial interface is in use. See the section entitled “RS-
485 Interface” for connection and communication information.
The “RS-485” interface connector is located on the rear of the IT-30B directly
under the “Display” connector.
Connecting to the Analog Interface
The model IT-30B comes standard with an analog interface. The analog interface
allows the IT-30B to be controlled by a PLC with standard analog and Digital I/O.
The connecting cable for this interface is not supplied by Clinton Instrument
Company. The cable composition is normally dictated by the PLC, but ordinarily
22-gauge conductors (individually shielded or shielded pairs) are required. The
maximum length of the cable is also determined by the equipment the IT-30B is
being connected to. However, it is recommended that the cable length not
exceed 10 meters.
See the section entitled “Analog Interface” for the details regarding this
interface.
Installing the CompactCom™Module (Optional)
The model IT-30B comes standard with a Fieldbus Communications Interface. This
interface will allow the installation of several fieldbus options. (DeviceNet,
Ethernet IP, Modbus TCP, Profibus, Profinet)
To enable the Fieldbus Interface the proper CompactCom™module will need to
be installed into the IT-30BX spark tester.
•First remove the Anybus Slot Cover from the rear of the spark tester.
•Remove the CompactCom™module from the packaging.
•Slide the CompactCom™module into the open slot on the rear of the
spark tester.
•Secure the CompactCom™module by tightening the 2 screws.
See the section entitled “Fieldbus Interface” for the details regarding this
interface.

Connecting the X3B (Optional)
Unpacking the X3B
Remove the following items from the carton:
1. X3B Horn/Light Tower with mounting plate. Note: If the X3B was ordered
for the BD-22 electrode, the carton should contain the BD-22 mounting
plate (part #91243).
2. Power Cord (part #03780)
3. A 4 conductor cable, with a 9-pin terminal block connector on one end and
a 10-pin connector on the other. (part #91247)
Connecting the X3B
1. Decide which side of the spark tester you wish to mount the X3B. Note that
you may have to remove the small plate from the X3B chassis and secure it
to the opposite side so that the green X3B terminal block is accessible from
the spark tester back panel. Mount the X3B using the mounting plate and
the (4) bolts that attach the end guard to the spark tester, as shown in the
picture to the left.
2. Make sure the spark tester is off before wiring to the X3B.
3. Locate the 10-pin green terminal block on the back of the X3B and the 9-
pin terminal block on the back of the spark tester. The X3B is supplied with
a 4-conductor cable. The 10-pin connector will plug into the X3B terminal
block and the 9-pin connector will connect to the spark tester terminal
block. Prior to inserting them, pins 1-5 of the 10-pin connector should be
wired to accessory equipment with 22 gauge or larger, stripped back 1/4”
(6mm) and fed into the green terminal block connector at the proper pin
numbers, as described on the following page. Pins 1-3 of the 9-pin
connector should be wired as described on the following page.
4. When wiring the two units, notice that pins 5-8 on the spark tester are now
being used to communicate with the X3B. The functions of pins 5-8 on the
spark tester have now been transferred to pins 1-5 on the X3B terminal
block. When the wiring is complete, plug in the power cords to both X3B
and the spark tester.

HV ON Indication:
Dry relay contact pins
1&2 will close when
the test voltage
exceeds 500v. For an
indication that HV is
ON in the electrode,
wire a lamp or
auxiliary device* here.
HV ON Relay
*When connecting auxiliary equipment to dry relay
contacts pins 1, 2, 3, 4, or 5, observe maximum ratings of
120VAC at 2 amps or 240VAC at 1 amp.
External Reset:
To reset the spark tester fault
relay with an external switch,
wire a momentary switch**
between pins 1&3. When
these contacts close, the fault
relay will return to a normal
state. The interval that the
contacts are closed must
exceed 50 ms.
HV Enable:
CAUTION For HV on the
electrode, install a normally
closed switch or relay
contact** between pins 1&2.
This switch or relay should
open automatically when the
wireline stop switch is
activated or be opened
manually by the system
operator when the line stops.
FAILURE TO DO SO COULD
RESULT IN A FIRE HAZARD If
the HV remains ON in the
electrode when your line is
stationary, the wire
insulation in the electrode
will heat and there is a
danger of combustion.

Process Control:
To activate external
lights,alarms or relays*
when a fault occurs, wire
them between dry relay
contact pins 5,4 & 3.
If the Lch function is ON
(set on the front panel),
the dry relay contacts will
remain closed until the
RESET button is pressed or
when pins 1&3 are closed
by remote switch
or relay. If the Lch
function is OFF, the dry
relay contacts will return
to normal state after the
interval known as the
PCd (Process Control
Duration, set on the front
panel) has elapsed.

Spark Tester Controls
ON/OFF Power Switch
This switch is located on the rear panel of the spark tester.
Voltmeter
The voltmeter will indicate the high voltage present at the electrode. The
voltage is displayed in kV. When the output is set to 1,000V the display
will read 1.0. A reading of 10.2 indicates that the test voltage at the
electrode is 10.2kV DC.
This display can also display a “Percent Load” value and the “Set Point”
value by pressing the “A” Button. These values will be displayed
momentarily on the Voltmeter display and then will return to displaying
the spark tester voltage at the electrode.
“A” Button
Pressing the “A” button will momentarily cycle the Voltage display
through the “Percent Load” and the “Set Point” Values.
UP/DOWN ARROW (VOLTAGE ADJUST) buttons
The spark test voltage may be adjusted from 0 to 30,000 volts in 100 volt
increments by pressing the up and down arrow buttons under the
voltmeter. Press and hold a button to increase the speed at which you
change the voltage setting.
Fault Counter
The 3-digit fault counter registers a count each time any fault type is
detected in the electrode. This display can also momentarily show 4
additional fault counts by pressing the “B” button. These fault counts are
Pinhole, Metal Contact, Multiple pinhole, Gross Bare wire. Press the CR
button to reset the number of faults on the counter to 0.
“B” Button
Pressing the “B” button will momentarily cycle through the 4 additional
fault count values. (Pinhole, Metal Contact, Multiple Pinhole, Gross Bare
Wire)
“CR” COUNT RESET button
Pressing the “CR” button will reset all fault count values.

FAULT light
The FAULT light will illuminate in response to any fault condition and will
mirror the Any Fault Alarm. It also indicates that the Any Fault Alarm relay
contacts are in fault condition, activating any accessories that are
connected. If the Any Fault Alarm output function is configured to the
LCH mode the fault light will remain on, otherwise the FAULT light will
turn off automatically. The FAULT light can be turned off in 3 ways: (1) by
pressing the “R” button below it; or (2) by closing a momentary switch or
relay contacts wired between Pins 1 & 3 of 9-Pin green panel terminal
block on the rear panel; (3) though one of the serial communication
interfaces.
“R” RESET button
Pressing the “R” button will reset all fault conditions and their
corresponding Relay output. The RESET button will have no effect on the
number of faults registered on the fault counter.
High Voltage On Lamp
The high voltage On Lamp will turn on when the high voltage
output level is above 500V.
Bead Chain Electrode
When the spark tester power is ON and the clear protective cover is
down, the test voltage set on the spark tester front panel is applied to
the product under test as it runs through the electrode. 1”, 2”, and 3”
bead chain electrodes are available. Other electrodes are available.
Please contact factory for details.
Clear Protective Cover
The clear cover protects the operator from coming into contact with the
energized electrode.
Safety Interlock switch
This switch turns OFF the high voltage in the electrode when the clear
protective cover is lifted. Do not attempt to defeat the safety interlock
switch.
Safety end guards
Metal end guards on each end of the high voltage test module prevent
the operator from reaching into the energized electrode. The test
product should be centered in the electrode to avoid damage to the
product.
