(Inputs 1 to 6)
4.1 Before doing the wiring
To carry out wiring, remove the unit's rear cover (Notes).
(1) For the power cable, use a 600V vinyl-insulated cable (JIS C 3307) or a cable with equal or supe-
rior performance to this.
(2) Use compensating leads for thermocouple inputs.
(3) To avoid the effects of induction noise, keep input signal leads as far away as possible (at least
30cm) from power supply lines and lines carrying heavy current. Also, wherever possible use a
shieled cable and earth one point of the shield.
(4) For wiring the terminals, use a maximum of 2 crimp style terminals.
Notes
(1) To remove the rear cover, put a finger in a cable
through-hole in the cover, gently raise the cover
and then pull outwards.
(2) After wiring up the input terminals, always re-
place the rear cover in its original position so as
to ensure proper compensation of reference contacts for thermocouple inputs.
(3) We recommend the use of insulation-sleeve
solderless terminals (using M4 thread) for connecting wires to terminals.
4.2 Connection of wires to terminals
(1) Input terminals
➪ Connect signal leads for each channel.
(2) Alarm, external control unit (option)
➪ Connect the alarm signal outputs and ex-
ternal control signal inputs (for alarms 1
to 6, external controls 1 to 3).
(3) Alarm unit (option)
➪ Connect the alarm signal outputs (for
alarms 7 to 12).
(4) Power supply terminal
➪ Connect the power cables to AC/AC ter-
minals. Connect to a noise-free, stabilized power supply.
This is an 100 to 240V AC free power supply.
(5) Ground terminal ➪ Effect type 3, Grounding (not more than 100Ω) of the G terminal.
(6) Transmission terminal (option) ➪ Connect the transmission signals.
CAUTION
Alarm unit are of overvoltage category I.
Other signal (input, communication interface) should be SELV (safety separated from
hazardous voltage).
4 - 1INP-TN4PHAV-E
(1) Wiring of input terminals
(1) There are individual input terminal numbers for different channels.
(2) Make connection in accordance with the relation between number of input signals by type designa-
tion and channels (see section 1.3).
(3) If you decide to change the type of input signals after your purchase, be sure to remember to wire
up the requisite channel accordingly.

(3) Caution on connection of input signal through barrier
A) Thermocouple input and resistance bulb input
Perform "Calibration of measured value" with the input connected to the barrier recorder because
the barrier internal resistance is added and causes an error in the measured value.
For the calibration method, refer to Item 9.4.
B) When using Fuji Zener Barrier (PWZ), a power source 100V AC line (85 to 132V AC) should be
used to ensure safe operation of the unit.

5.1 Loading chart paper
Step 1 Riffle and loosen the recording paper so as to
prevent overlapping feed.
Step 2 Open the front flap, push the paper hold-down
roller to the right and detach it.
To replace chart paper while recording is in
progress, carry out the above after pressing
the RECORD key to stop recording.
Step 3 Raise the lever that is on the right.
This releases the lock, the paper feeder moves
downward and paper holder can be seen.
5 - 1INP-TN4PHAV-E
Step 4 With round holes (small holes) in the recording
paper located on the left-hand side, set the recording paper so that its leading edge with both
corners cut off comes to this side. Then insert
the leading edge into the container with the printing face located upward.
Butt the recording paper to the left-hand end and
set the recording paper in this position at this
time. Furthermore, be careful so that the recording
paper will not be located aslant. In addition, droop
the first two or three folds of the recording paper into the recording paper receiver.
Step 5 Press the chart paper so that its holes engage with
the sprockets and then, without further adjustment, return the paper holder to its original place.
Make sure that the chart paper does not lift up.
Note: If chart paper lifts up and contacts the re-
cording head, it can prevent ink coming
out. It can also cause improper paper feed.
Step 6 Return the paper hold-down roller to its original
position.
Check to make sure that the chart paper is straight
and that its holes are properly engaged with the
sprockets.
In order to prevent the chart paper slipping to the
left or right,

Step 7 Press the FEED key and check that the chart
paper is fed out smoothly. (Feed out about 2 folds
of paper.)
<If the paper is not fed out smoothly, go through
the procedure from Step 2 again.>
Note 1: Selection of chart paper
The chart paper greatly affects the quality of the printed recording and it is also related to problems such as paper jamming, etc.
Please be sure to use the pure-quality chart paper specified by us.
Chart paper type:PEX00BL1-1000B (100 equal divisions, no time lines)
Note 2: Use of the recorder after it has been left unused for a long time
If the recorder is left unused for a long time with chart paper still in the main unit, the paper 'packs
down' and if the recorder is used straightway there can be problems of paper jamming, etc.
If you use the equipment after it has been left unused for a long time, first press the FEED key to
feed out 2 to 3 folds of the paper.
Reference 1: Chart paper length
The chart paper is approximately 20m long. This permits about 31 days continuous printout at a paper feed speed of 25mm/h.
Reference 2: Chart paper end mark
The amount of chart paper remaining is indicated by digits (units : cm) on the right-hand
side of the paper. When there is only a small amount left, red letters appear on the righthand edge.
If the recording paper runs out completely, a recording paper end indicator displays 'Chart
end' in the display section and recording automatically stops.

5.2 Recording head installation (replacement)
The recording head has ink and a head for recording in an integral assembly.
If the ink gets used up or if it happens that there is a fault, the head can easily be replaced.
As the recording head is a very delicate element, please carefully read the 'Precautions" that are noted
later and handle the head with care during replacement work.
Step 1 Get the recording head ready by taking it out of
its aluminium pack.
Step 2 Tear the tape.
Open the cap by turning it in the direction indicated by the arrow.
(If the head is not going to be used for a long
time, close the cap back in its original position.)
The cap is integral with the head unit. Turn it
about 180° until it stops against the tope of the
head.
Step 3 Lightly press the nozzle surface (the surface
from which ink is discharge). Make sure that
the cloth is properly impregnated with the 4
colors blue, red, yellow and black.
First press the cloth against the surface for 2
to 3 second; if the 4 colors ooze out, it is OK.
How to close the cap

the RECORD key.
• Raise the lever that is on the right. This releases the lock comma only, the recording paper feed section pulls forward an recording paper holder can be seen.
Step 5 Push the chart paper hold-down plate spring
down.
Step 6 Hold the recording head horizontal, line it up
with the carriage in the main unit slide it in
slowly and press it firmly until it does not go in
any further. Take care not to bang the nozzle
surface of the hand.
Also, avoid touching the nozzle surface with your
hand.
Do not touch the connector at the rear
of the carriage to avoid the risk of minor electric shocks.
5 - 5INP-TN4PHAV-E
Step 7 Move the chart paper hold-down plate spring
back up to its original position.
(Check that the plate spring is not contacting the
recording head.)
Step 8 Return the chart paper holder to its original setting.
The above completes installation of the recording head.
The recording head is a consumable part. Replace it with a new one when the ink it contains is used up.
Recording head replacement
Draw out the recording head in the manner that is opposite to what is described in Step 6 of the
recording head setting procedure, and place it with a new recording head.
Always carry out the following procedure after replacing a recording head.

Precautions in handling recording heads
Note 1: If recording is halted and the recorder is not used for a long time
Carry out the following in order to prevent jamming and drying-up of the ink.
Remove the recording head from the main unit, make absolutely sure the cap is closed
properly and store the head in a cool, dark place (average temperature 5 to 30°C).
If the head is left installed in the recorder:
Do not switch off the power to the recorder and do not close the cap.
* Periodically, there is an automatic discharge of ink to prevent drying-up.
Leave the recording paper in place in the recorder.
If it is not possible to keep the power switched on, make sure that the cap is closed.
In this case, follow Step 4 and Step 5 of 'Recording head installation' to lower the recording
paper holder and hold-down plate spring and tighten the cap.
Note 2: At the start of use of a recording head
If you are starting to use a new recording head or if the recorder has been left unused for a long time,
always wipe the head's nozzle surface lightly with the accessory cloth and check that the 4 colors black,
blue, red and yellow ooze out properly into the cloth. (See Section 5.2.) Also, after normal recording
is possible. See Section 6.3 for the way of printing out a test pattern.
When the working environment is 15°C or less, perform print-out of "test pattern" after period of
several minutes has elapsed since the recording head was mounted. (The recording head has a built-in
heater.)
Note 3: Handling recording heads
• Do not knock or shake recording heads as this can cause faults.
• The inks are not harmful but they are very difficult to remove if they adhere to the skin or to clothes,
so handle heads carefully in order to avoid staining. Also, do not disassemble them.
• If, by accident, it happens that ink gets into your eyes, wash thoroughly with water as an emergency
measure and then immediately consult a specialist doctor.
Note 4: Storage of recording heads
When they are delivered, recording heads are in aluminium packs.
If you are not going to use a head straight-away, leave it sealed and store it in a cool, dark place with an
average temperature of 5 to 30°C.
5 - 7INP-TN4PHAV-E
Note 5: Shipping of recording head
• Do not ship the unit recording head after the aluminum pack was opened up.
If it is necessary to ship the unit recording head under avoidable circumstances, be sure to close the
cap, and ship it as contained in a boxboard in the state where vibration and impact are eased using
cushioning materials.
• Always close the cap if you are transporting a head while it is still installed in the recorder main unit.
Note 6: If the ink is not sprayed.
(1) Hold the recording head with turning the nozzle surface down-
ward and push the side strong till spilling two drops.
(2) Absorb the standing ink on the nozzle surface with the cloth at-
tached.
(3) Hold the cloth to the nozzle surface again to find all colors flowed
onto cloth.
* When working environment is 15°C or less, perform print-out
of "record" or "test pattern" after a period or several minutes
has elapsed since the recording head was mounted. (The recording head has a built-in heater.)
Reference: Ink consumption
This varies depending on the conditions of use but with a chart speed of 25mm/h and recording of
constant input, the amount of consumption is as follows.
About 1 year..............................in the case of 1, 2, 3 continuous records
About 6 months.........................in the case of 6 continuous records
About 3 months.........................in the case of 12 continuous records
An ink dry-up warning-detection function produces a warning display in the display section and a
warning print-out the recording paper.
(See Section 11.12 for an example of print-out.)
