INTRODUCTION
Read this manual carefully, making full use of its explanations and instructions. The “Know How” of safe, continuous,
trouble-free operation depends on the degree of your understanding of the system and your willingness to keep all
components in proper operating condition. Pay particular attention to all NOTES, CAUTIONS, and WARNINGS to avoid
the risk of personal injury or property damage. It is important to understand that these NOTES, CAUTIONS, and
WARNINGS are not exhaustive. Nexen cannot possibly know or evaluate all conceivable methods in which service may
be performed, or the possible hazardous consequences of each method. Accordingly, anyone who uses a procedure
that is not recommended by Nexen must first satisfy themselves that neither their safety or the safety of the product will
be jeopardized by the service method selected.
The Nexen-Nireco Splice Detector System is used to
signal the presence of a splice as it passes through a
web fed machine. In many applications, the pressure
between two nip rolls or the printing rolls in a machine is
so high that two thickness of web passing through will
cause problems.
FIGURE 1FIGURE 1
FIGURE 1FIGURE 1
FIGURE 1
Nexen-Nireco Splice Detector Systems can sense these
splices and actuate a normally open or normally closed
relay for about three seconds.every time a splice passes
through. On a complex machine with many of these
tightly nipped points it is often necessary to install several
Splice Detector Systems to “follow” the splice through
the machine and signal the various nip rolls to open at the
appropriate time.
COMPONENTS
Nexen-Nireco Splice Detector Systems are composed of
a JD100 Splice Sensor and JC 100 Splice Controller
(See Fig. 1 ).
JD 100 Splice Sensors are composed of a light
transmitter on one arm of a sensor housing and a light
receiver on the other arm.
JC100
Splice Controller
JC 100 Splice Controller provides the excitation signal to
the JD 100 lamp, and also receives and interprets the
return signal from the receiver. The logic board allows
the JC 100 to constantly compare the amount of light
received with the amount previously received. In this way
it “knows” immediately when the double thickness of a
splice is passing through the light path, allowing less light
to pass.

JD100 SPLICE SENSOR
1. Align JD100 vertically in respect to web and mount
JD100 with transmitter pointing down and receiver
pointing up (See Fig. 2).
2. Adjust JD100 so that web is approximately half way
between transmitter and receiver.
MOUNTING
NOTE: JD100 and JC100 are electronic components and should be mounted in a shock and vibration free area
which has an ambient temperature of more than 32oF, [0oC] and less than 122oF [50oC].
JC100 SPLICE CONTROLLER
1. Locate JC100 within four feet (two meters) of JD100.
NOTE: JC100 cable may be extended up to 100 feet
using 18 AWG six conductor cable.
2. Install JC100 into control panel (See Mounting
Dimensions).

ELECTRICAL CONNECTIONS
1. Using cable provided with JD100 connect JD100 to
terminal strip of JC100 (See Fig. 3).
2. Provide AC power (115, 127, 220, 240 VAC) to
Terminals 10 and 11 (See Fig. 3)
3. Connect Terminal 12 to ground (See Fig. 3).
NOTE: The output signal is a dry contact relay
closure available at Terminals 7, 8, and 9.
Terminal 8 iscommon. A normally open
contact, which closes when the system
“sees” a splice, is available between
Terminals 7 and 8. A normally closed
contact, which opens when the splice is
present is available between terminals 8
and 9. Maximum rating for these contacts
is 200 VAC, 2 amps. The contacts stay in
their energized position approximately
three seconds each time a splice passes
through the sensor. FIGURE 3

SETUP AND CALIBRATION
SETUP
1. Remove four Screws securing Cover of JC100 (See
Fig. 4)
2. Using Voltage Select Jumper, select correct voltage
as applied to terminals 10 and 11, select from 115,
127, 220, or 240 VAC (See Fig.5).
3. Set Power Switch (located on Front Panel) to ON,
Power Lamp should glow (See Fig. 6
4. Test sensor calibration by inserting a single thickness
of the lightest material to be run on the machine into
the light beam of JD100. The sensor has been pre-
calibrated at the factory and the single thickness of
web should cause the Output Lamp to light and the
Relay to energize for approximately three seconds.
5. If the system passed the above test, set Power
Switch to OFF and reinstall Cover and four Screws.
The system is now calibrated and ready to run.
6. If the single thickness of the lightest material did not
trigger the Output Lamp and Relay, proceed to
calibrate system.
CALIBRATION
1. If the test material did not trigger the system, re-insert
test material into light path of JD100.
2. Measure voltage between Terminals 5 and 6. Adjust
Trim Pot marked ADJ (located on Front Panel) until
voltage is between 8.5 and 10.5 VDC (See Fig. 6.
3. System sensitivity is adjusted with VR2 (located on
JC100 Main Board . This should normally set to 5, or
the middle of the scale. Sensitivity can be increased
by clockwise rotation of VR2 and decreased by
counterclockwise rotation (See Fig. 5.
Too much sensitivity will cause false
triggering when there is a minor change in
ambient light. Low sensitivity may cause the
sensor to occasionally “MISS” a splice as it
passes through the sensor.
4. After completing calibration, set Power Switch to
OFF, and reinstall Cover and four Screws. System is
now calibrated and ready to run.
Remove screws. Remove cover.

OPERATION
1. With a single thickness of web in the light path of
JD100, set Power Switch to ON. Power Lamp
should light (See Fig.7.
2. Output Lamp may or may not light. If Output Lamp
lights, it will go off after approximately three seconds.
3. In either case, the system is calibrated to one
thickness of the web after approximately three
seconds. Any time light transmission is decreased
by the presence of a double thickness of web, the
Output Lamp will light and the Relay will change
state for approximately three seconds.
4. The system is re-calibrated for each different web run
on the machine in the same manner. After three
seconds of running, the system re-calibrates itself to
the new web thickness.
MAINTENANCE
1. JD100 sensitivity is affected by foreign material on
the Light Transmitter and Receiver. Periodically
clean these surfaces with a soft, clean, dry cloth.
2. Incandescent lamps deteriorate during their service
life. Replace lamp if it is burned out.
a. Remove Screw A on Transmitter Housing
(See Fig. 8).
b. Pull Lamp Holder out of Transmitter
Housing. (See Fig. 8).
Care must exercised when removing Lamp
from Transmitter Housing to prevent
damage to Lamp Wires.
3. Push Lamp in while rotating Lamp counterclockwise
to remove Lamp from Transmitter Housing.
4. Reverse above procedure to install new Lamp into
Transmitter Housing.
