	earthed, it would result in electric shocks or malfunction.
	• Be sure to connect power source that matches the rating. Con-
	nection of incorrect rating of power source may lead to fire.
	• Before starting wiring work, be sure to turn OFF the main power
	to prevent electric shocks.
	• Wiring materials to be used must meet the rating. Use of mate-
	rials which do not withstand the rating may cause a fire accident.
Caution on Maintenance
DANGER	• When disposing of the recording head, put it in a vinyl bag
	and seal it to prevent the diffusion of ink. It should be handled
	as an imcombustible object when disposing of it.
	• Ink is harmful to human body. Observe the following emer-
	gency treatments.
	. When ink gets in eyes, wash out for at least 5 minutes
	immediately with much clean water, and ask your doctor
	for treatment at once.
	. When ink gets on skin, wash out and clean skins with
	soap and water.
	. When ink is breathed in, move to a clean place immedi-
	ately. If necessary, ask your doctor for treatment at once.
	• Do not touch the connector at the rear of the carriage mount-
	ing the recording head to avoid the risk of electric shocks.

4. WIRING

4.1Before wiring

For thermocouple input, be sure to use a compensated lead wire.

Input signal cables should be wired separately as far as possible (30cm or more) from power lines and high-voltage lines to minimize the effect of inductive noise. Shielded cables should preferably be used. In this case, the shield braids should be earthed at one point.

Notes

(1) At the completion of wiring of the input terminals, be sure to close the rear cover to ensure the compensation of reference contact when thermocouple input is used.

(2) For connection of lead wires to terminals, use of sleeveinsulated clamping terminals (for M4 screws) is recommended.

4.2Caution on power source wiring

This recorder has no power fuse. Mount a power fuse outside the recorder as necessary. Recommend fuse rating : AC250V, 1A

When connecting power cable and earth cable to terminals, be sure to use crimp style terminals with insulated sleeves (M4 screw).

For power cable connection, be sure to use 600V vinyl insulated cable or equivalent.

Before making a wiring work, be sure to turn OFF the main power to prevent

the risk of electric shocks. After wiring, be sure to close the cover. DANGER Wiring materials to be used must meet the rating. Use of materials which do

not withstand the rating may cause a fire accident.

Wring work must be performed as specified. If the unit is not earthed, it would result in electric shocks or malfunction.

The recorder is not provided with a power fuse.

Use an external power fuse.

CAUTION Rating : T1A, 250V AC or equivalent protection.

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 us.

Chart paper type: PEX00DL1-5000B (50 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 15m long. This permits about 31 days continuous print-out at a chart speed of 20mm/h.

Reference 2 Chart paper end mark

The remainder of chart paper is indicated by numerals on the right of paper (unit : 10cm). When it becomes small, a red band will appear on the right to indicate that the chart paper needs to be replaced with new one.

(Note) The recorder is not provided with a chart paper end sensor. When chart paper is used out, stop recording or replace the chart paper with new one.

Get the recording head ready by taking it out of its aluminium pack.

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 top of the head.

•Lightly attach the supplied cloth to the nozzle

(ink ejecting side) to such up the ink. For the standard head, check to make sure that 4-color ink, blue, red, yellow and black, are soaked into the cloth (for the 2-color head, 2 colors of ink are soaked).

First press the cloth against the surface for 2 to 3 second; if the 4 colors ooze out, it is OK.

Note) Do not use any cloth other than the supplied one. Also, do not rub the nozzle with the cloth.

Step 4	• Press the REC key. Operate the recorder after it
	has been set in recording stop mode.
	• Open the front door and press down the paper
	feed unit drawout lever.
	The paper feed unit will be drawn out.

Step 5 Recording head

	• Hold the recording head horizontally, 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.
Nozzle cariage	• Take care not to bang the nozzle surface of the
	head. Also, avoid touching the nozzle surface with
	your hand.
	Do not touch the connector at the rear
	CAUTION of the carriage to avoid the risk of mi-
	nor electric shocks.

Step 6

Set the paper feed unit in its original position.

The above completes installation of the recording head.

The recording head is a consumable part. When the built-in ink is used out, replace the head with

new one.

It comes in 2 types, one is for the 1, 2 continuous recording (PHZH2002) and another for the 6 dot recording (PHZH1002). Choose the type of the head according to the recording mode of the recorder.

Recording head replacement

Draw out the recording head in the manner that is opposite to what is described in Step 5 of the recording head setting procedure, and replace it with a new recording head.

Always carry out the following procedure after replacing a recording head.

(1) Test pattern print-out

Print out a test pattern to check that normal recording is possible. See Section 6.3 for the way of printing out a test pattern.

(2) Adjustment of analog trend recording positions

Referring to Section 9.2, readjust the zero and span on the recording paper.

Precautions in handling recording heads

Handling recording heads

• Do not knock or shake recording heads as this can cause faults.

DANGER • 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.

•When the recording head is empty of ink, it should be disposed of as a incombustible object or returned to our office for reuse (recycling).

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.

Draw out the paper feed unit using the recording head setting method Step 4 .

Open the indicator 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 ink oozes out properly into the cloth. (See Step 3.)

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 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.

Note 4 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 impack 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 5 If the ink is not sprayed.

Hold the recording head with turning the nozzle surface downward and push the side strong till spilling two drops.

Absorb the standing ink on the nozzle surface with the cloth attached.

Hold the cloth to the nozzle surface again to find the ink flowed onto cloth.

When ink does not come out, repeat the above operation ( through ).

*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

When recording at 20mm/h of chart speed and a given input, the consumption of ink is as shown below, though it depends on operating conditions.

1 continuous recording ---------	about 20 months
2 continuous recording ---------	about 12 months
6 dot recording ------------------	about 8 months

6.5Displays and print-outs on detection (cancellation) of alarms

When an alarm has occurred, its contents appear on the display section. They appear for 1 second

every 3 seconds while displaying a measured value.

Note) In case of fixed display of measured value, the alarm status for the fixed channel only appears.

Example of alarm display

Example: Alarm No.1 and No.2 of ch 1 has occurred.

When an alarm detected and cancelled, the relevant details are printed on the right-hand side of the

chart paper.
On detection:	The time of detection, channel No., type of alarm,

---- Print-out color: Red (6 dot), Red (1,2-continuous)

On cancellation: The time of cancellation, channel No., type of alarm

---- Print-out color: Black (6 dot), Blue (1,2-continuous)

Channel 1 No. 1 H alarm
←release
←	Release time: 17 : 40

Channel 1 No. 1 H alarm generation

Generating time: 17 : 37

If an alarm is detected or a cancellation is made during data print-out or list print-out, the alarm print-out takes place after completion of the data or list print-out.

Up to a maximum of 30 alarm detection cancellation information can be stored and sequentially printed out, but if the storage capacity is exceeded because of a large number of detections/cancellations in a short time, information in the overflow portion is discarded and cannot be printed out.

6.6Displays and print-outs on occurrent of burnt-out

If a thermocouple or resistance bulb has burnt our, its contents appear.

Example of alarm display

Example: Ch 1 burnt out.

Note: Trend recording overswings toward the maximum side of the recording range.

If a burn-out occurs, its contents are printed on the right of recording chart (in red).

Example of burn-out print-out
