2. INSTALLATION

Place this instrument in the following place not to affect the measuring accuracy and recording operation adversely.

2.1. Mounting Place

(1) Industrial Environment

Select a place being separated from electric field and magnetic field generation sources and also free of mechanical vibrations and shocks.

• Overvoltage category II (EN standard)

• Pollution degree 2 (EN standard)

• Altitude 2000 m or less

• Working place Indoors

(2) Environmental Temperature and Humidity

Avoid exposing this instrument to the direct sunlight, and avoid sealing around it to prevent temperature rise.

• It is desired to place it in where the ambient temperature is stable at about 23 °C and the humidity is stable at about 50 % RH.

• Place it in where free of being exposed to hot blast (70 °C or higher) and not exceeding the condition of ambient temperature (0 to

50 °C) for preventing failure and deformation of it.

• Place it in where being free of a heat source near its terminals and out of the wind for reducing measuring errors.

(3) Atmosphere

• Avoid using this instrument in an inflammable gas atmosphere for safety.

• Avoid using this instrument in any place where dust, smoke, vapor, and other substance exist.

• Substance example: Organic gas, Inorganic substances such as hydrogen sulfide and ammonia gas, and Low-molecular

siloxane

Mechanical relay is used for input switching of this product, and it may cause contact point failure with the above substances. Many silicone-related materials include low-molecular siloxane; therefore, attention is necessary under the environment where a lot of silicone-related adhesion bond, coating materials, and others are used. The low-molecular siloxane included in adhesion bond and coating materials strips in the air for a certain period even during and after hardening. If you are worried about impact of these substances, contact your nearest CHINO’s sales agent.

After the instrument is exposed in the atmosphere with even slight sulfur components for a long time period in the state of power switch off, it may not be powered on even the power switch is turned on. This symptom occurs because sulfidizing film generated on the connection surface of the power switch causes contact failure. If the power switch is turned on and off several times, the generated sulfidizing film breaks and the instrument recovers. However, if it is exposed in the atmosphere of sulfur components for a long time period, electronic parts other than the power switch are affected and cause failures. Avoid using it in the atmosphere of even slight sulfur components.

Substances which Affect Instrument

Impact of Sulfurization by Sulfur Atmosphere

(4) Mounting Angle

• Lateral tilting: 0 to 10 degrees

• Longitudinal tilting: Forward tilting: 0 degrees

Backward tilting: 0 to 30 degrees

A mounting angle other than the specification above may affect recording performance.

4. CONNECTIONS

The following are cautions before connections. Make sure to observe them for securing safety and reliability.

(1) Power Source

Use a single-phase power that has a stable voltage and no distorted waveform to prevent the wrong operation.

Switch and Overcurrent

Add a switch and overcurrent protective device (multi-point type: 250 V, 2.5 A/pen type: 250V, 3.15A) to the power source for preventing an electric shock during connection work. This product has no replaceable fuse.

Turn off the Power Source

Before connecting to the power supply and

input/output terminals, make sure to turn off the power

source for preventing an electric shock.

(2) Keep away from Strong Power Circuit

Avoid placing the input/output cables to be close to or in parallel with any strong power circuits including power line. Keep them more than 50 cm away from the circuits if close to or in parallel with the circuits.

(3) Keep away from Heat Source

(Thermocouple Input)

For thermocouple inputs, keep the terminals away from a heat source (a material generating heat) for reducing an error of reference junction compensation. In addition, avoid exposing the terminals to the radiation of direct sunlight or place them where wind blows.

Protective Device

before Connections.

4.2 Cautions on Connection 

(4) Avoid Noise Source

Keep connection cables from a noise source as far as possible. Otherwise an unexpected trouble may occur. Take a remedial measure if the cables cannot be kept away from a noise source.

Major noise source Measure

Electromagnetic switch Power line having distorted waveform Inverter Thyristor regulator

(5) Use Crimp Style Terminals

1. Mount a crimp style terminal as a connection cables’

termination for preventing the looseness or disconnection of terminals and a short-circuit failure between terminals.

2. For the crimp style terminal, use an insulation sleeve for

preventing an electric shock.

(6) Unused Terminals

Avoid using any unused terminals for relaying. Otherwise, electric circuits may be damaged.



Treat connected cables securely so as not to allow them to be hooked by a person or a substance. Otherwise, the connections may be disconnected or cut and cause an electric shock or other accidents.

Treat Connected Cables Properly

Insert noise filters between the power supply and input/output terminals.

(1) Connection of Measuring Input Terminals

Make sure to turn off the power source before connection for preventing an electric shock.

1. Loosen the fixing screw of the input terminals cover and slide the cover up.

2. Open up the input terminals cover slightly (the cover is removed from fixing screw) and slide back down (prior to the slide up position).

3. In the state of slid down position, open the cover up until it stops (Figure below).

4. The input terminals cover stops at middle position easily (Refer to

figure below: side view).

(3) Connection of Thermocouples (TC) Input

Use a thermocouple wire (or compensation lead wire) to the input terminals of this instrument. If a copper wire is used halfway, a noticeable measuring error occurs. Avoid using a pair of thermocouple wires in parallel with the other instruments (controllers, etc.), otherwise troubles may occur (Indication fluctuation, indication errors, and others may occur.). If the instrument has the burnout function (optional), avoid using it in parallel with other instruments (otherwise it may affect other instruments).

10Ω or less. Use 3 codes which have the equal resistance value.

Channel

A high voltage may be applied to the measuring input terminals due to common mode noise (common mode voltage applied between the measuring input terminal and protective conductor terminal). The tolerance of the common mode voltage is 30VAC or 60VDC or less. Make sure that the common mode voltage is lower than the tolerance. Make sure to close and mount the terminal cover with a screw after the connection for preventing an electric shock and protection of input cables. Closing and mounting the terminal cover allows reducing errors of reference junction compensation.

For the terminals for DC voltage and thermocouple input, channels are insulated (functional insulation, Note 3); however, for the terminals for resistance thermometer, channels have equal potential (All b terminals are connected within the instrument.).

Note 3) Functional insulation: Insulation necessary for normal operation of instruments without protective function against electric shocks (avoiding ground loop formulation of instruments)

If input is opened in the state of no burnout function, indication/recording values become unstable. Indication/recording may be placed in the lower limit position, or in the higher limit position temporarily; however, that state is not guaranteed.

Input Terminals for 1-, 2-, 3-point Types

The input terminals arrangements for 1-, 2-, 3-point type specification and pen type differ. Refer to the input terminals diagram on the back of the instrument and (5) Measuring Input Terminals Arrangement mentioned later.



For Inkpad Loading

Make sure to pull out the inner unit first when loading or replacing the inkpad. Do not load or replace the inkpad by just taking out the scale plate without pulling out the inner unit. Scale plate is placed at adjusted position and it may cause indication error. Also, depending on the placement status, not only it may operate normally but also it may cause failures.

(2) Inkpad Loading



Attached Inkpad

• Appropriate quantities of ink are filled in advance. Avoid filling ink in that state. Otherwise the inkpad with too much ink may have ink drops and others which cause failures.

• Although the period depends on use conditions, the inkpad can be used for about 2 months with standard specifications and under standard operational conditions.



Attachment/removal of Inkpad

When attaching or removing the inkpad for loading/replacement and ink filling, make sure to turn the power off or to be in the state of RECORD OFF. Otherwise the indication mechanism operates during inkpad being attached/removed and unexpected force is applied to the mechanical parts then the instrument may be damaged. Replacing the inkpad at the state of RECORD OFF, do not move indication mechanism manually. It may cause failures.

1) Pulling out the Inner Unit Pressing the both of levers (Inner unit lock levers) of the right and left under the rack inward (to the direction of the arrows in the figure below), hold the right side of the chart cassette (the part directed by the hand in the figure below) and pull it out.



Pulling out Inner Unit

Pulling out the inner unit fast may damage the inner unit and the instrument. When the inner unit is pulled out quietly about 6 cm long, it stops with the middle stopper. Avoid pulling it out further. Otherwise it may be damaged.

2) Inserting Inkpad In the state of the inner unit being pulled out to the middle stopper, insert the inkpad to the pad axis of the dotting mechanism.

3) Loading Inkpad In the state of the inkpad inserted, turn the inkpad with fingers slowly. When the pin part of the inkpad meets the pad chase of the dotting mechanism, the inkpad falls and gets loaded. In the state of the inkpad being loaded normally, the inkpad does not turn. When it can be turned by a finger easily, it is not loaded normally. In this case, check the state of the inkpad falling down turning it slowly.

4) Placing Back the Inner Unit Press the both sides of the chart cassette until the both levers of the right and left under the rack are opened outward making a sound of “click”. The levers are to secure the inner unit; therefore press them all the way to lock the unit.



Handling of Pointer

・

Avoid touching the pointer. If force is added, the pointer may be damaged.



Filling up Ink

• Filling up Ink When the recording color of points becomes light, add 1 or 2 drops of the attached supplementary ink to the pad (cotton of the inkpad to apply ink). At this time, avoid pressing the top of the supplementary ink to the pad, otherwise the pad is damaged and the ink cannot be attached easily on recording. In addition, the filled amount of ink cannot be seen, so overfilling of ink may happen.

On filling the ink, make sure not to mix up the colors of the inkpad and the supplementary ink. Pay attention especially to blue/purple and red/scarlet which are easy to be mixed up. Check carefully the number (recording channel number) of the supplementary ink and the number of the inkpad recording color. In addition, the type of supplementary ink depends on the number of input points. Refer to “Reference: Type and Recording Color”, (1) Preparation, mentioned early and (3) Ink Filling Color of Inkpad mentioned later.

• Duration of Use When ink is filled, the duration of use is half or less compared with the one when the ink was filled initially (The duration varies depending on the ink colors.).

• It is Important Not to Add Ink Too Much When ink is added, note not to add it too much once (1 or 2 drops are enough). Make sure to drop it. Excess ink generates drops and attachment of ink, and then causes failures of mechanical parts.

• Life of Inkpad When ink filling is repeated, ink absorption of the inkpad is degraded. If the inkpad is used continuously in that state, recording quality is degraded, drops and attachment of ink are generated, and then failures of mechanical parts occur. Replace an inkpad with new one when ink is filled four or five times.

The consumption level of inkpads depends on use conditions. Early replacement is recommended when recording state gets worse and ink absorption is degraded on ink filling.

1) Pen Replacement Mode Pen replacement mode moves cartridge pen to the position where is easy to load/replace the cartridge pen. If each pen is at the position of 20 to 80% of recording range, this operation is unnecessary. If the position of the each pen is overlapped, remove from the 3rd pen and load from the 1st pen.



Attachment/removal of Cartridge Pen

When loading or replacing the cartridge pen, make sure to turn the power off, be in the state of RECORD OFF (all pens are INDICATE OFF) or perform under the pen replacement mode. Otherwise the dotting mechanism operates during cartridge pen replacement and unexpected force is applied to the mechanical parts then the instrument may be damaged.

1. Bring the cartridge pen DOWN by pulling down the pen lift lever

down located at right side of the inner unit.(refer to (4) Pen Lift

2) Lift up of the 1st pen scale plate Only for the 1st pen scale plate of the 3 pen specification, structure allows scale plate to move. For 3 pen specification, when replacing the cartridge pen of the 1st pen, lift the scale plate up and perform cartridge pen loading. For lifting up the scale plate of the 1st pen, lift up lower part ((the part directed by the hand in the figure below) of lower limit side (left side) of the scale plate. The scale plate would be up until lower part of the scale plate of 2nd plate.

3 pen specification: the scale plate of the 1st pen is lifted up



For moving scale plate

For lifting up the 1st pen scale plate of the 3 pen specification, make sure to perform operation at the far left side. If the operation is done by position other than this, scale plate may be deformed and cause errors and failures. Also, the scale plate stops at the stopper position. If the scale plate is lifted up more than stopper position, it may cause failure and damage.

Do not move blank scale plate (without scale printing) of the 2 pen specification located at the bottom. The scale plate may be deformed and cause errors and failures.

3) Load /Replacement of the Cartridge Pen

1. Remove the cap of the pen, bring the color line in the front then

insert protruding portion of the right side into the hole of the pen

holder. Turn the cartridge pen clockwise to load to the pen

holder.

At this time, state of lifting the cartridge pen slightly while

protruding portion of the right side of the cartridge pen is inserted

into the hole of the pen holder creates easy performance.

2. To remove the cartridge pen, turn the cartridge pen counterclockwise with slightly pushing the protruding portion of the left side of the cartridge pen.



Removing the pen cap

Do not load the cartridge pen while pen cap is on. It may cause errors and failures.

5.2 Cartridge Pen Loading (For pen type)

Remarks

Except for the 1st pen of 3 pen specification, it is easy to perform cartridge pen loading at the pen up state. Also, pen up state prevent ink stain by the cartridge pen on the chart paper (refer to (4) Pen Lift Lever Operation mentioned later).



Handling of Recording Structure

Avoid moving recording structure right/left by force. If moving recording structure is needed for loading /replacement of the cartridge pen use the “Pen Replacement Mode Function” (refer to Pen Replacement Mode mentioned earlier)

Remarks

For new cartridge pen, ink may not come out easily. Before loading the cartridge pen, write with the cartridge pen manually on the paper.

Remarks

The cartridge pen is disposable. Ink consumption level varies by usage. However, it can be used for about 1.5 months under standard environment. (Continuous recording of about 600 to 1000m)



Handling of Pointer

Do not touch the pointer. Putting the force to the pointer may cause indication error and damage.

Remarks

Stop operating and not using for long term or using the unit just for indication and recording is unnecessary, remove the cartridge pen and put the pen cap on then store to prevent drying out of the pen tip and prolong the life of the ink.

(5) Installing the Chart Cassette into the Inner Unit

Guide rails are located at the right and left of the inner unit. Align the chart cassette to the guide rails and push it into the inner unit until it clicks (The both inner unit lock levers are opened outward.). Now the chart paper loading completed.

When the chart cassette is loaded, backlash of the chart feed mechanism (allowance of mechanism) is generated. Note that the chart paper is not fed for a period of time until this backlash is removed.

• Method to minimize the period of no feeding of the chart paper by the chart cassette loading.

(1) After the chart cassette loading, put back the chart feed

gear lightly until it stops, and then the chart feed mechanism backlash can be minimized.

(2) With the front FEED key operation, operate the FEED key

until the chart paper is fed, and then the time of no chart feeding is almost none.

Guide

When Chart Cassette is Loaded

(6) Chart Feed Check after Chart Loading

1. Turn the power on.

2. Press FEED key to check that the chart paper is sent smoothly. When the FEED key is pressed continuously, the chart paper is fed slowly for about 2 seconds, and when the key is pressed further, the chart paper is fed fast (Refer to 6.3 Chart Feeding Operation, (2) Chart Feeding).

3. If the chart paper is not fed smoothly, reload the chart paper.

The remaining amount of the chart paper is indicated with the red number at the right side of the chart paper. When the remaining is few, the red end mark and characters appear at the right end of the chart paper.

The chart cassette of this product has a flat surface in the front which allows notes.

The structure of this product allows manual feeding of the chart paper (Refer to 6.3 Chart Feeding Operation); therefore, if force is added downward (feeding) on notes writing, the chart feed mechanism moves down and the chart paper feeding may be displaced. Even if the chart feed mechanism for manual feeding does not move, the chart paper may be displaced with the mechanism backlash. Pay attention to the chart paper not to be moved on writing. When the chart paper is moved downward, time axis is displaced, and the chart paper is not fed for the period equivalent to the backlash of the chart feed mechanism.

3. The instrument move to the operation mode

2) Initial Operation Lamp Indication and Time

1. Right after the power is on, the power lamp is lit in orange,

and the chart paper lighting is lit in high brightness.

2. Right after that, the power lamp is switched to green, and the

chart paper lighting is switched to the specified brightness. Simultaneously all of the indication lamps, chart speed (setting parameter), setting mode and pen selection (for pen type) are lit.

3. Each of the chart speed (setting parameter), setting mode

and pen selection (for pen type) indication lamps are turned off after about 2 seconds.

4. Become operation mode/lamp indication.

* 1 to 3 of the initial operation takes several to dozen seconds.

3) After Initial Operation End After the initial operation ends, this instrument moves to the operation mode. Indication/recording operation and state of indication lamp depends on the state of switches when the power is turned on (Refer to (4) Transition to Operation Mode mentioned later).

This product is the analog recorder in which input state is recorded with analog trend, however, digital processing is performed with a microcomputer within the instrument.

When the power is turned on, it takes about 6 seconds at least and up to a dozen seconds for initialization operation within the instrument before indication/recording operation starts. When output of the instrument is used, it takes more time for normal output state after the power is turned on compared to the analog instrument with an analog circuit.

(3) Fitting Chart Paper Time Line

• Operate FEED key or feed the chart paper manually to fit the dotter recording position/cartridge pen recording position and the time line of the chart paper.

For time line fitting, put back the chart feed gear lightly until it stops after the manual feeding to minimize the chart feed mechanism backlash. Adjust the time line in this state.

• Fit the time line after the power is turned on.

Even if the time line on the chart paper is adjusted to the dotter recording position/cartridge pen recording position, there will be a gap (3.6 mm) on the time line of the chart paper caused by the chart feeding function when turning power on again after a momentary power interruption, etc.,

Time Line fitting with Manual Feeding

When Momentary Power Interruption Occurred

2) Manual Feeding The chart paper can be fed by turning the chart feed gear forward (downward).

When the chart paper is fed manually, backlash of the chart feed mechanism (allowance of mechanism) is generated. Note that the chart paper is not fed for a specified period depending on the state of the manual operation.

• Method to minimize the period of no feeding of the chart paper by the manual feeding

1. After the manual feeding, put back the chart feed gear

lightly until it stops, and then the chart feed mechanism backlash can be minimized.

2. With the front FEED key operation, operate the FEED key

until the chart paper is fed, and then the time of no chart feeding is almost none.

Numbers of 1 to 24 are printed on the left side of the chart paper at intervals of 25mm. This is a time scale for running with the chart speed of 25mm/H.

For manual feeding, due to a certain constructional limit of resolution, the time line may not be adjusted accurately.



Only Chart Paper Feeding Operation

Only feeding operation can be performed manually with the chart feeding mechanism. The chart feed mechanism backlash can be put back lightly; however, further backward operation cannot be performed. Otherwise it may be damaged.

For the pen type, there is a gap on the time line of the recording position of each pens (7.1 refer to Recording Operation (Pen type)). For the adjustment of the time line, adjust cartridge pen recording position of the standard pen and time line.

6.4 Recording Operation (AUTO CH/ INDICATE Switch)

(1) AUTO CH/INDICATE Switch (Refer to 3.2 Display

Operation Part.)

[Dot-printing type] AUTO CH Switch

1) When AUTO CH Switch is Up Position (ON State) Channels are switched with 6-second interval (Option: 3-second interval for dotting interval of 3 seconds), and indication/recording is performed (Recording mode). Update input linked to channel switching interval.

2) When AUTO CH Switch is Down Position (OFF State) No recording is performed, and the input of the channel indicated by the dotter is taken in with 1-second interval and only indication is performed (One-point indication mode). The procedure for the one-point indication mode is as follows.

1. When the channel indicated by the dotter becomes the one

you want to indicate, place the AUTO CH switch in the down position.

2. The alarm lamp blinks for about 1.5 sec., and chart feeding

and dotting operation stop. Only pointer moves in accordance with the input value.

3. To restart recording, place the AUTO CH switch in the up

position.

On one-point indicate mode, update input data by every one second. Start moving indication by input data and when stop moving (indication position), start moving by next data of input update interval. The data inputted during indication is moving. It is not to be a target of indication.

When AUTO CH switch is switched (changed), the alarm lamp blinks for about 1.5 seconds. The indication channel information during the one-point indication mode is written to the internal nonvolatile memory (EEP-ROM).

During the recording mode the indication position is corrected for every 12 points; however, during the one-point indication mode it is not corrected. If the position of the indication mechanism is displaced by external causes or others, the displacement continues without change. For the one-point indication mode usage for a long term, it is recommended to switch to the recording mode regularly.

Switching of AUTO CH Switch

Notes on One-point Indication Mode Usage

Indication (recording) positions are corrected per 12 points. On the position correction operation, the indication moves to around the lower limit position, and temporary standby (stop) operation is performed. The position correction operation is performed for every 12 points regardless of the number of input points.

• 12-point instrument: Once for one interval (12 points)

• 6-point instrument: Once for two intervals (6 points x 2 times)

6.5 Pen Marker (Only for 2/3 pen type) 

(1) Pen Marker

This is for 2/3 pen type. Pen not using for recording of input update can be used for marker line recording. At the event, press left/right key at an arbitrary timing moves recording position and perform marker line recording. Moving resolution of one press of left/right key is 2.5% and continuous operation is available. Movable range is 0 to 100% of recording.

1) For 2 Pen Type

When 2nd pen is at the standby state (INDICATE OFF), 2nd pen can be used as a pen marker.

1. Turn 2nd pen switch down (OFF State).

2. Press “ENTRY” key until next reaction.

3. Press “ENTRY” key for more than 3 seconds light “ALARM”

and “CAL” lamp intermittently (key operation mode 2) then release the “ENTRY” key.

4. Press either left/right key once moves indication/recording of

2nd pen to the direction of the key pressed for 2.5% (4.5mm). Every press of left/right key moves indication/recording 2.5%.

• At the power on, it is on the “Key Operation State 1”. Pen marker operation is disabled. “Key Operation State 2” is mode for pen marker operation. At this state, setting change or adjustment is not available (pen replacement mode and chart paper lighting brightness dimming are available). On “Key Operation State 2” pressing the “MODE” key returns to the “Key Operation State 1” (“ALARM” and “CAL” lamp turn off).

First press of the left/right key moves indication/recording to the recording position of 2.5% resolution. Therefore only for the first movement, moving amount is less than 2.5%.

• Returning 2nd pen INDICATE switch up (On State) changes 2nd pen to the recording mode. When recording is OFF state (INDICATE switch of the all pen is OFF), pen marker function is invalid.

2) For 3 Pen Type When 3rd pen is at the standby state (INDICATE OFF), 3rd pen can be used as a pen marker. Function is same as 2nd pen of 2 pen type.

• Returning 3rd pen INDICATE switch up (On State) changes 3rd pen to the recording mode. When recording is OFF state (INDICATE switch of the all pen is OFF), pen marker function is invalid.



Operation of the Pen Marker

Make sure to operate pen marker indication/recording position by left/right key. Do not move pen mechanism directory. The mechanism may be damaged.

Pen marker position is not hold at power OFF (including short power interruption). Power ON after these conditions, pen marker stops at the lower limit position (refer to 7.3 Behavior on Abnormal Input, under range).

Pen marker position is enabled only when pen marker function is in the use. Once pen marker function is disabled (including power OFF and short power interruption), position information is also disabled. Set again if necessary.

6.8 Alarm Setting

(1) Alarm Setting

1. A value you desire for an alarm to be activated can be set for the indication value (setting resolution: 0.25 %).

2. The alarm value for an upper limit alarm/lower limit alarm which is common to all channels for dot-printing type and individual set by each pen for pen type can be set.

3. Alarm setting and clear (alarm determination release) for upper limit alarm/lower limit alarm are performed collectively for all channels for dot-printing type and individual set by each pen for pen type (Refer to “Alarm Setting Value”, the right.).

4. In any channel become alarm value (lower limit value or less/upper limit value or more) the alarm is activated, and the alarm lamp lights. In addition, when the alarm output (optional) is available, the contact signal of upper limit alarm/lower limit alarm can be output on alarm activation.

5. The alarm lamp continues to light until all alarms activated are reset.

(2) Setting Procedure for Alarm Values

Refer to the flow chart mentioned later.

1) Transition to Alarm Value Setting Mode

[Dot-printing type]

Alarm setting can be performed only from the one-point indication mode. In the recording mode (RECORD ON) when the dotter is switched to the channel for alarm setting, place the switch to the one-point indication mode. Note that if the AUTO CH switch is placed in the down position right before dotting, dotting is performed and then the channel is switched. When a single scale is used, you do not need to check the channel indicated by the dotter.

2) Setting Procedure for Alarm Values Check that all DIP switches are off. (Refer to 6.2 Operation/Setting Change (3) DIP Switch Function.)

Dot-printing type: RECORD ON, one-point indication mode Pen type: Operation mode

RUN lamp off ALARM lamp blinks. (Alarm lamp off: *1)

*1 Alarm judgment is not performed during alarm value setting mode. When switch to alarm value setting mode at alarm activation, alarm lamp is turned off.

MODE

[Pen type] Alarm setting can be performed from any operation mode. Specifying input channel can be performed from alarm setting mode.

• Setting value [Dot-printing type] For a single scale, set values are reflected to all channels. For the double/triple scale (optional), the setting value is reflected to the channel with the same scale as the channel of the dotter on transition to the alarm setting mode.

[Pen type]

The setting value is reflected at the every pen input.

• Setting value clear [Dot-printing type] For a single scale, alarm values of all channels are cleared. When the double/triple scale (optional) is used, the alarm value of the channel with the same scale as the channel of the dotter on transition to the alarm setting mode is cleared. [Pen type] The alarm value is cleared at the every pen input.

For settings with indication mechanism operation, always check responses of key operations (switching of display) and completion of indication mechanism operation when performing key operation unfailingly since wrong operations or setting may occur.

Note: The indication lamps show the state right before key

operation. The dark color shows lighting and faint color shows blink state.

For dot-printing type, there is no lamp indication part for pen selection.

6. OPERATION/SETTING

When the alarm level is selected, there are “LL” and “HH” levels indications at the both sides of “L” and “H” under the indication lamps; however, they cannot be selected on alarm setting. The “LL” and “HH” levels indications are reserved for handling of special specifications.

3) Setting Method for Alarm Values (1) Moving of Pointer

When the alarm level is selected in the alarm setting mode, the pointer moves to the current alarm value. If “L” level (lower limit alarm) is selected and an alarm value is not set, the pointer moves to the under-range position (leftmost). If “H” level (upper limit alarm) is selected and an alarm value is not set, the pointer moves to the over-range position (rightmost) (Refer to “Position of Pointer When Alarm Values Not Set" below.).

(2) Fixing of Alarm Setting Value

For setting alarm values, move the pointer to the scale you desire for the alarm to be activated pressing right/left keys. While the pointer moves, the alarm lamp repeats short blinks. When ENTRY key is pressed, the alarm lamp blinks, and the alarm setting value is fixed.

The alarm setting value is fixed when ENTRY key is pressed (the alarm setting value is written within the instrument). When the alarm setting value is set (changed), the alarm lamp blinks for about 3 seconds.

6.8 Alarm Setting

The pointer moves 0.2 mm by pressing the right or left key

once (release immediately after pressing).

The moving resolution of the pointer is 0.2 mm, and the

setting resolution of the alarm value is 0.45 mm (0.25 %).

* The moving resolution of the pointer is twice or more

compared to the setting resolution of the alarm setting value.

The pointer moves continuously when the right or left key is

pressed for about 0.3 seconds or more. When the key is

continuously pressed further, the moving speed of the pointer

becomes faster after about 2 seconds. If the key is released,

ointer slows down its speed immediately and stops.

* When MODE key is pressed during setting, the setting mode

is finished and the operation mode is placed back.

If the instrument is left during the setting, the setting mode is

finished and the operation mode is placed back after about 1 minute. In the case where the alarm value is to be set (the pointer can be moved), the state is continued.

* Indication/recording operation is interrupted during the setting.

(3) Clearing Alarm Setting Value (Alarm Judgment

Release)

Clear the alarm setting values in the alarm setting mode (Refer to (2) Setting Procedure for Alarm Values mentioned early.). Clear the alarm setting values of all channels commonly for dot-printing type and individually for the pen type.

1) Clearing All Alarm Level Setting Values While the alarm level select lamp (“L” or “H” level) blinks, press the both right and left keys simultaneously for 3 seconds or more (Press two keys simultaneously for 3 seconds. Refer to

6.2 Operation/Setting Change (2) Key Operation Type). The alarm lamp blinks and the alarm setting value is cleared.

* For the dot-printing type, all alarm value settings with the same scale are cleared and for the pen type, all the alarm value settings of selected pens are cleared.

2) Clearing Each Alarm Level Setting Values

1. After the alarm level is selected, in the state where the pointer

indicates the current alarm setting value, move the pointer to the end of either side (0 % or 100 %) of the scale plate with the right/left keys. The pointer moves to the position of 0% or 100 % when the right/left keys are pressed continuously.

2. When the right/left keys are pressed again, the pointer

moves to the position of over-range or under-range.

3. Press ENTRY key in this state. The alarm lamp blinks and

* With this clearing method, each alarm level setting value is

cleared individually.

Under-range

the alarm setting value is cleared.

Over-range

After the alarm level is selected, in the state where the pointer indicates the current alarm setting value, press the both right and left keys simultaneously for 3 seconds or more. The alarm lamp blinks and the alarm setting value is cleared (If the right and left keys are pressed not simultaneously but differently in time, the pointer moves to the direction of the key pressed earlier, and the alarm setting value is not cleared.).

After the alarm value is cleared, the instrument becomes in the state of alarm level selection, and the pointer moves to the standby position of lower limit side. In this case, only the alarm setting value of the selected alarm level is cleared.

The provided alarm index sticker can be attached to the scale position of the scale plate with alarm setting as an alarm index. Stickers with different directions can be attached to identify the upper limit alarm and lower limit alarm. Use the stickers according to your purposes. Stickers can be relocated 2 to 3 times. The sticker may come off and etc. when multiple relocation or long time period has been passed after the attachment. Interfering with the pointer movement, it may cause abnormal operation. Check attachment of the sticker regularly.

Another Clearing Method for Alarm Setting Values

Alarm Index Sticker

(4) Confirmation of Alarm Setting Value

When the alarm level is selected in the alarm setting mode, the pointer moves to the scale position of the current alarm setting value; therefore the alarm setting value can be confirmed. In this state, when MODE key is pressed, the alarm setting value is not changed and the operation mode is placed back.

After the alarm setting value is confirmed, even when the position indicated with the alarm setting value is moved with the right/left keys, if MODE key is pressed, the alarm setting value is not changed and the operation mode is placed back.

To change the alarm value, press the ENTRY key in the state where the pointer indicates the alarm value, and then the value is changed. When it is changed, the alarm lamp blinks. Unless the alarm lamp blinks, the alarm setting value is not changed.

Make sure to confirm the correct setting of the alarm value with this operation.

When the alarm setting (Refer to 6.8 Alarm Setting) is performed, the alarm is activated.

7.2 Alarm Activation/Reset and Behavior

(1) Timing of Alarm Activation/Reset on Recording Operation for Dot-printing type (Recording Operation by Dotter)

When the AUTO CH switch is placed in the up (recording mode) position, the instrument takes input of the channel to be indicated to the channel number indication of the dotter (For example, CH3: When dotting is performed to CH2, and the channel number indication is switched to CH3), performs alarm judgment of its channel (such as CH3), and moves to the scale position equivalent to the input value during dot recording operation.

1) Example of alarm activation/reset (for upper limit alarm)

1. State of indication of CH2

2. The indicated value of CH2 is recorded.

The dotter drops to record CH2.

3. The channel number indication of the dotter is switched to CH3.

When the channel number indication of the dotter is switched to CH3, the alarm of CH3 is activated.

4. The pointer moves to the scale position equivalent to the input

value of CH3.

When the alarm judgment of CH3 is performed again after a round of dot recording channels, it is decided whether the alarm is reset or activated continuously by the indicated value of CH3. (A) to (C) alarm reset in the figure right are described below.

(A) Since the indicated value is not within the deadband but in the normal range, the alarm is reset. However, when the lower limit alarm is set and the indicated value that exceeds the lower limit alarm setting value causes the lower limit alarm, or when an alarm occurs in another channel, the alarm lamp continues to light.

(B) Since the indicated value is within the deadband range, even if it is lower than the alarm setting value, the alarm is not reset (Refer to

When the AUTO CH switch is placed in the one-point indication mode (no recording, only indication), for only the indicated channels, alarms are judged and output. For other channels, alarms are not judged (The alarm states of other channels are held.).

2) Pen type Input value of pen of which INDICATE switch is up position (ON: normal recording mode) reaches alarm setting value (below lower limit value or above upper limit value), alarm is activated immediately. When the input value is below the alarm setting value including deadband, alarm is reset immediately.

Perform alarm judgment and output only for pen input which is in the recording mode (up position: the mode which performs indication/recording operation) by INDICATE switch. Alarm judgment is not performed for pen input which is in the standby state (down position: indication/recording stop) by INDICATE switch. (Pen input of which INDICATE switch is down position: standby state, even if the alarm is in the activated state in the recording mode, alarm activated state is reset.)

For One-Point Indication Mode

INDICATE Switch and Alarm Judgment

3) Setting mode Alarm judgment is not performed during setting of alarm value setting, user indication adjustment (refer to 9.1 User Indication Adjustment /Indication Check) and shift programming (refer to 9.2 Shift Programming). Even if the alarm is in the activated state, moving to these modes reset alarm activation.

(3) Alarm Occurrence Indication

When the alarm is activated, the alarm lamp lights.

1. For dot-printing type, it continues to light until all the activated alarms are reset.

2. For pen type, it continues to light until all the activated alarms of pen inputs are reset. When place INDICATE switch of all alarm activated input pen down position (OFF), alarm lamp is turned off. When place INDICATE switch up position (ON), if the alarm is in the activated state, alarm lamp lights again.

(4)Output on Alarm Occurrence (Optional)

For the output state on alarm occurrence, refer to 4.5 Alarm Output Terminal (Optional) (2) Alarm Output.

1) Dot-printing type The upper limit alarm output and lower limit alarm output are common output of all channels. Output is held until alarms of all channels are reset.

2) Pen type Alarm output is performed for each pen individually.

7. OPERATION

(1) Behavior on Over-range/Under-range Input

If values that exceed the measuring range (0 % to 100 %) are input, the pointer moves to only slightly outside of the both sides of the scale plate (0 % or 100 %). If values that exceed this position are input, the pointer is fixed at this position.

Under-range

In the case of the figure right, the pointer is fixed at the under-range position for (1), and at the over-range position for (2).

(1) Under-range Position that moved to about 0.45% (about 0.8mm) lower side from the record 0% position

(2) Over-range Position that moved to about 0.45% (about 0.8mm) upper side from the record 100% position

(2) Behavior on Burnout (Optional)

The burnout is the feature to move the pointer to either end of the scale plate when a sensor (thermocouple or resistance thermometer) is disconnected.

Type of burnout

Lower limit burn Pointer moves to under-range position.

Upper limit burn Pointer moves to over-range position.

Specify the type of burnout correctively for the relevant scale of all input channels.

The input disconnection is detected by applying a pulse voltage. Parallel operation cannot be performed because the parallel connection affects other instruments (such as a controller).

8. OPTION

A DC current input can be measured by connecting a shunt resister (attached for current input specification) to the input terminals and converting the current input into a voltage level.

8.1 Shunt Resistor for Current Input 

(1) Shunt Resister (Attached) and Measuring Current

Range

The shunt resistor converts DC current input into DC voltage (Refer to “Shunt Resister and Measuring Range”, the right.).

(2) Connections

Connect a shunt resistor to each channel to measure the DC current. Make sure to connect the shunt resistor attached before using.

Connect one shunt resistor to one channel.



Cautions on Connection 2

Make sure to connect the shunt resistor before inputting the DC current. If the DC current is input without the shunt resistor, the voltage of the power source is directly applied and it may cause damage to the instrument.

Cautions on Connection 1

(3) Measuring Range

When the current input is within the measurement range of 4 to 20mA, the input to the instrument is set to 1 to 5V.

If the measuring range for current input other than the range of 4 to 20mA is desired, specification of the input range is required. The instrument has been set for a voltage input. Before using the instrument, confirm that the indication is according to the input by connecting the attached shunt resistor to the instrument.

For current input, output load resistance is limited at the current source side (supply side of current input). Confirm that there is no problem with the shunt resister (250Ω). If measured with the edge of the output load resistance, matching with the measuring current source side, impact of connections, and others cause reduction of linearity of current output, and primary accuracy may not be obtained.

The dotting interval is short; therefore when the measured values vary a little, points overlap. For slow chart speed, the chart paper may tear. When the measured values vary a little, specify the standard dotting interval or set the chart speed which is faster.

Use with Dotting Interval of 3 Seconds

For “Dotting interval 6 sec.” of the standard specification, the provided inkpad can be used for about 2 months under standard operational conditions; however, for “Dotting interval 3 sec.”, the usage duration is about half of one of “Dotting interval 6 sec.".

(1) User Indication Adjustment

1. If the input value does not accord with the indicated value when

the maximum or minimum value of the input scale is input, the indicated value can be adjusted with user indication adjustment.

2. With this adjustment, two kinds of adjustments can be

performed. One is the adjustment for both of “zero position and span position” and the other is the adjustment for “only zero position”.

3. For the dot-printing type, the correction values after the

adjustment of one of channels are applied to all other channels. However, for the double/triple scale (optional), the correction value is reflected to the channel with the same scale as the adjusted channel.

For the pen type, perform the adjustment for every pen input.

4. Perform the adjustment under the reference operating

condition.(Right-top table, “Reference Operating Condition”)

(2) Indication Check

1. To keep accuracy rating of measurement, the annual indication

check is recommended.

2. Perform the check under the reference operating condition

(Refer to “Reference Operating Condition”, right-top table.).

(5) Indication Check Procedure Input the minimum (Min) or maximum (Max) value of the input scale by standard tools and confirm that this input value accords with the indicated value. If the input value does not accord with the indicated value, perform user indication adjustment.

9.1 User Indication Adjustment /Indication Check 

(6)User Indication Adjustment Procedure

Refer to the flow chart mentioned later.

[Dot-printing type]

1) Transition to User Indication Adjustment Mode User indication adjustment can be performed only from the one-point indication mode. In the recording mode (RECORD ON) when the dotter is switched to the channel with input connection for user indication adjustment, switch to the one-point indication mode. Note that if the AUTO CH switch is placed in the down position (One-point indication mode) right before dotting, dotting is performed and then the channel is switched. When a single scale is used, you do not need to check the channel indicated by the dotter.

[Pen type] User indication adjustment can be performed from any mode of operation mode. Specification of input channel can be performed in the user indication adjustment mode.

For the instrument with burnout function, the input disconnection is detected by applying a pulse voltage of about 10ms every 6 seconds (Input update cycle. For optional “dotting interval of 3 seconds”, every 3 seconds). When the output voltage of the voltage generator is measured by a digital multi-meter or others on the indication checking, the indication of the digital multi-meter may not be stabilized by the pulse voltage for detecting the input disconnection.

The user indication adjustment is adjustment to fit indication values to input values. If the shift programming (Refer to 9.2 Shift Programming.) has been performed, even the user indication adjustment is performed, the indication value shifts for only shift programming adjustment.

For operations with indication mechanism operation, wrong operations or setting may occur; therefore always check responses of key operations (switching of display) and completion of indication mechanism operation, perform key operation unfailingly.

Note: The indication lamps show the state right before key operation. The dark color shows lighting and faint color shows blink state.

3) Adjustment Method

1. Give Input. Give input which accords to the adjustment position (Zero side: Left end of the scale plate = Minimum value of the scale/Span side: Right end of the scale plate = Maximum value of the scale) from the channel to be adjusted on user indication adjustment. When the selection position is selected, the pointer moves to the indication position which accords to the current input value. For dot-printing type, input is updated every 3 seconds, and the alarm lamp blinks once on input update. For pen type, input is updated every 125ms, and the alarm lamp blinks in 1 second interval on input update.

2. Input Value is Set. When the input value is set, press ENTRY key. When the ENTRY key is pressed, the input updated value is set. After that input is not updated; therefore, even if input values are changed, the pointer does not move.

3. Adjustment Position is Set. For user indication adjustment, move the pointer to the adjustment position with pressing the left/right keys (Refer to “ Pressed”.). While the pointer moves, the alarm lamp repeats short blinks. When ENTRY key is pressed, the alarm lamp blinks, and the indication adjustment value is set.

The user indication adjustment is set when ENTRY key is pressed (The adjustment value is written within the instrument.). When the adjustment value is specified (changed), the alarm lamp blinks for about 3 seconds.

The pointer moves 0.1mm by pressing the right or left key once (immediate releasing after pressing) (If the key of opposite direction is pressed once continuously, the pointer may not move because of the indication deadband.). While the left/right keys are pressed, the pointer moves continuously receiving the keys in 0.1 second cycle. When the key is released, the pointer stops immediately. The alarm lamp blinks once every movement of 0.1mm.

Input is given which accords to the adjustment position (Zero

side: Left end of the scale plate = Minimum value of the

scale/Span side: Right end of the scale plate = Maximum value

of the scale) from the channel to be adjusted on user

adjustment, however, if the input value is not within the

adjustment range of the instrument, normal adjustment cannot

be performed.

● Adjustment range

Zero side: -1.1 to +5.0 mm

(-0.6 to +2.7 %)

Span side: -5.0 to +1.5 mm

(-2.7 to +0.8 %)

If the input value is outside of the adjustment range above,

normal adjustment cannot be performed.

Whether the input value is within the adjustment range can be

judged with the pointer which moves to the both directions of

right and left with the first right/left keys operation after the input

value is set (Refer to “

with Left/Right Keys Pressed”.). If the operation of the key for

the pointer to move to the adjustment limitation side is not

received (The pointer does not move and the alarm lamp does

not blink.), normal adjustment cannot be performed.

* If it is required that the indication value shifts fully for an

arbitrary value, perform shift programming (Refer to 9.2 Shift

Programming mentioned later.).

* When MODE key is pressed during setting, the setting mode

is finished (If setting of the input value is waited, MODE key operation is not received.).

* When nothing is performed during setting, the setting mode is

finished after about one minute. In the case where the setting of the input value is waited or the position of the pointer is to be set (the pointer can be moved), the state is continued.

* Indication/recording operation is interrupted during the setting.

The user indication adjustment includes two methods as follows.

(1) Adjustment of both of “Zero side and span side”

(2) Adjustment of “Only zero side position” (Refer to (8) Adjustment of Only Zero Side Position mentioned later.)

With the user indication adjustment, adjustments of zero side and span side are performed separately; however, avoid adjustment of only span side. Otherwise adjustment errors may occur.

(7) Clearing User Indication Adjustment

Clearing of the user indication adjustment value is performed in the user indication adjustment mode (Refer to (6) User Indication Adjustment Procedure mentioned early.). When the user indication adjustment value is cleared, the adjusted value within the instrument is placed with the value on shipping.

1) Clearing User Indication Adjustment Value While the adjustment position selection lamp (“ZERO” or “SPAN”) blinks, press the both right and left keys simultaneously for 3 seconds or more (simultaneous 3 seconds press of two keys. Refer to 6.2 Operation/Setting Change (2) Key Operation Type). The alarm lamp blinks for about 3 seconds and the user indication adjustment value is cleared.

* Dot-printing type: All adjusted values with the same scale are cleared.

* Pen type: Adjusted value of selected pen input is cleared.

■ Adjusted value [Dot-printing type]

The adjusted value is reflected to all channels. However, for the double/triple scale (optional), the adjusted value of the channel with the same scale as the channel of the dotter on transition to the indication adjustment mode is reflected.

[Pen type]

The adjusted value is reflected to pen input.

■ Clearing [Dot-printing type]

The adjusted value is cleared for all channels. However, for the double/triple scale (optional), the adjusted value of the channel with the same scale as the channel of the dotter on transition to the indication adjustment mode is cleared.

[Pen type]

The adjusted value of pen input selected in the indication adjustment mode is cleared.

Adjusted Value

(8) Adjustment of Only Zero Side Position

With the user indication adjustment, when the adjustment is performed only for the zero side position, the indication value of the input value is shifted to 0 % of the scale plate for the adjustment. If it is shifted to the right side, the input shifts to the right side wholly; therefore, the input which is equivalent to 100 % of the scale plate may become over-range. For the user indication adjustment for only 0 % position, the adjustment range mentioned in “ Adjustment”, 3) Adjustment Method, is the precondition. When the adjustment of shifting arbitrary amount is required, refer to 9.2 Shift Programming mentioned later.

When wrong operations are performed in the user indication adjustment mode, and if setting operation for the adjusted value is not performed with ENTRY key and the user indication adjustment mode is finished, nothing is changed. If the ENTRY key for setting of the adjusted value is operated after wrong operations are performed, abnormal data is written on the user indication adjustment value and the instrument malfunctions. If operation/indication failures occur due to abnormal user indication adjustment data, perform either one of the following operations.

(1) Shift Programming

1. If the indication values shift and are displaced over the scale or you want to shift and correct the input when the maximum or minimum value of the scale is input, the indicated value can be adjusted with the shift programming at the user side.

2. With this shift programming, the amount of ±10 % of the scale range can be adjusted.

3. For the dot-printing type, the correction values after the adjustment of one of channels are applied to other channels. However, for the double/triple scale (optional), the correction value is reflected to the channel with the same scale as the adjusted channel.

For the pen type, perform the adjustment for every pen input.

(2) Shift Programming Procedure

[Dot-printing type]

1) Transition to Shift Programming Mode Shift programming can be performed only from the one-point indication mode. In the recording mode (RECORD ON) when the dotter is switched to the channel for shift programming, switch to the one-point indication mode. Note that if the AUTO CH switch is placed in the down position right before dotting, dotting is performed and then the channel is switched. When a single scale is used, you do not need to check the channel indicated by the dotter.

Shift programming is a function where the percent of the scale for shift in the direction of plus or minus with the center (50 % of the scale) of the input scale as reference is adjusted with the moving amount of the indicated value. It is not a function where input is given and the current indication value is displaced. Shift amount must be decided with the scale in advance. If the correct adjustment is not performed, indication accuracy errors occur and the instrument malfunctions.

The shift programming is adjustment to shift indication values overall separate from the user indication adjustment. If the user indication adjustment (Refer to 9.1 User Indication Adjustment /Indication Check.) has been performed, the indication values as results of the user indication adjustment are shifted for the amount of the shift programming.

For operations with indication mechanism operation, wrong operations or setting may occur; therefore always checking responses of key operations (switching of display) and completion of indication mechanism operation, perform key operation unfailingly.

3) Adjustment Method

1. Setting of Adjustment Position Value For shift programming, move the pointer to the shift programming value with pressing the left/right keys (Refer to “ Pressed”.). While the pointer moves, the alarm lamp repeats short blinks. When ENTRY key is pressed, the alarm lamp blinks, and the shift programming value is fixed.

The shift programming is set when ENTRY key is pressed (The adjustment value is written within the instrument.). When the adjustment value is specified (changed), the alarm lamp blinks for about 3 seconds.

* When MODE key is pressed during setting, the setting mode

is finished.

When nothing is performed during setting, the setting mode

is finished after about one minute. In the case where the pointer position is to be set (the pointer can be moved), the state is continued.

* Indication/recording operation is interrupted during the setting.

While the left/right keys are pressed, the pointer moves continuously receiving the keys in 0.1 second cycle. When the key is released, the pointer stops immediately. The alarm lamp blinks once every movement of 0.1 mm. The pointer is switched to move by 0.5 mm continuously when the right or left key is pressed continuously for about 0.5 seconds or more. The alarm lamp blinks once every movement of 0.5 mm.

(3) Clearing Shift Programming Value

Clear the shift programming values in the shift programming mode (Refer to (2) Shift Programming Procedure mentioned early.). When the shift programming value is cleared, the adjusted value within the instrument is placed with the value on shipping.

1) Clearing User Programming Value While the CAL lamp lights intermittently for the dot-printing type and pen seletct lamp lights for the pen type, press the both left and right keys simultaneously for 3 seconds or more. While the adjustment position selection lamp “ZERO”/“SPAN” blinks (CAL lamp lights intermittently) after transition to the shift programming mode, press the both right and left keys simultaneously for 3 seconds or more (simultaneous 3 seconds press of two keys. Refer to 6.2 Operation/Setting Change (2) Key Operation Type). The alarm lamp blinks for about 3 seconds and the shift programming value is cleared.

* Dot-printing type: All adjusted values with the same scale are cleared.

* Pen type: Adjusted value of selected pen input is cleared.

When wrong operations are performed in the shift programming mode, and if setting operation for the adjusted value is not performed with ENTRY key and the shift programming mode is finished, nothing is changed. If the ENTRY key for setting of the adjusted value is operated after wrong operations are performed, abnormal data is written on the shift programming value and the instrument malfunctions. If operation/indication failures occur due to abnormal shift programming data, perform either one of the following operations.

Normal state is returned.

10.1 Routine Inspection 

(3) Cleaning for Moving Parts

Clean the main shaft (rotating shaft) and auxiliary shaft of the recording mechanism which performs recording every 6 months as a guide.

1. Turn the power off.

2. Open the door and pull out the inner unit (Refer to 5.1 Inkpad Loading.).

3. Pull out the chart cassette (Refer to 5.3 Chart Paper Loading.).

4. Wipe off the taint of the main shaft (rotating shaft) and auxiliary shaft of the recording mechanism with a soft cloth. For the pen type, wipe off each main shaft and auxiliary shaft of pens (Refer to the figure right.).



Cautions on Cleaning

Avoid moving the recording mechanism to right and left by hands. To move the recording mechanism, hold the part which fixes the belt of the recording mechanism and move it quietly. If you move it hard or move it holding other parts, it may be damaged. When the recording mechanism of multi-point type is moved, the chart paper lighting may shine; however, that is not abnormal.



Prohibition of Lubrication

• Avoid lubricating oil to the main shaft (rotation shaft) and

auxiliary shaft of the recording mechanism.

• Avoid lubrication to other mechanical parts including gears

with oil.

(4) Cleaning for Dotter (For dot-printing type)

If waste of the pad (ink-filled cotton) of the inkpad and remaining material of ink are attached to the tip of the dotter, the recording condition is degraded (such as bleeding). Clean the dotter when replacing the inkpad.

1. Turn the power off.

2. Open the door and pull out the inner unit (Refer to 5.1 Inkpad Loading.).

3. Pull out the chart cassette (Refer to 5.3 Chart Paper Loading.).

4. Wipe off the attached materials on the tip of the dotter (Refer to next section, Cleaning Part of Dotter) with a soft cloth ensuring not to rub hard.

5. Switch the dotter rotating the dotting main shaft gear (Refer to figure in next section, Manual Switching Operation for Dotter) on the right side of the inner unit one revolution forward (the direction of the arrow) (The dotter is switched one channel with one revolution.).

6. Repeat operations of 4 to 5 (6 times for 1 to 6-point specification and 12 times for 12-point specification).
