1.1 Features

Chapter 1 FEATURES AND FUNCTIONS

1.1 Features

This chapter describes the main features and functions of the µR1800 recorder. The µR1800 is equipped with all the functions which can be expected in a modern recorder,

whereas its functions also reflect the latest user requirements.

The µR1800 recorder is a precision measuring instrument that is equipped with many outstanding features:

Compact sized, high reliability: Its compact size (depth 220mm) allows you to install the µR1800 where only a limited space is available. In case of the pen model, a contact-free potentiometer and a brushless-DC servomotor contribute to its high reliability. In case of the dot printing model, high reliability is obtained by the use of high break down voltage solid-state relays.

Universal inputs: Inputs like DC-voltage, Thermocouple (TC), Resistance Temperature Detector (RTD), and Digital Input (contact) can all be conveniently used. There is no need to change any dipswitches; the type of input can be set using the keyboard.

Easy interactive setting: The setting procedure has been made very easy, by using only panel keys. The µR1800 asks you to select the desired settings, without the need for remembering difficult setting-codes.

Large informative operator display: The large sized, VFD, display shows the measured data (including the engineering units) or clock, and bargraph at the same time. There are two types of bargraph available: percentage-display, and center-zero display. Because of its 1%-resolution, the bargraph displays very accurately.

1. FEATURES AND FUNCTIONS

Continuous pen recording for up to four channels (pen model only):

Depending on your µR1800 model type, the µR1800 can measure up to four channels simultaneously. This allows you to decrease the number of recorders you require.

Universal power supply (except for /P1 model): The µR1800 accepts 90 to 250VAC (except 132 to 180VAC), and 50/60Hz without any problems, or need to turn switches. Therefore the µR1800 is compatible with a wide variety of power supplies.

High performance: The sampling speed of the µR1800 pen model is high at 125 ms, whereas the recording cycle of the µR1800 dot printing model is 6 ch./10 seconds, or 12ch./15sec., 18ch./20sec. or 24ch./30sec. depending on the model. The µR1800 is equipped with many functions. Special functions can be ordered as an option. Furthermore, its power consumption is low (4pen model; 30VA under normal operation conditions).

Easy maintenance: Because of the use of many contact-free parts, the need for maintenance has been decreased. The µR1800 is designed in modules, which decreases the time needed for maintenance extensively.

Closed case: The closed case of the µR1800 allows it to be used in many environments. The front door is in accordance with DIN 40050-IP54.

Computer interface and memory card: If equipped with this option, the µR1800 can store and retrieve measured data as well as setting data, using an IC memory card or directly from your PC. The available interface is RS-422-A.

IM 4H3B1-01E

Based on international safety standards: The µR1800 (except portable type) is based on international safety standards, such as the IEC 348.

WARNING

To prevent an electric shock, ensure the main power supply is turned OFF and connect the ground terminal using a class 3 resistance of 100Ω or less. For power and ground wiring termination, use “crimp on” lugs (for 4mm screws) with insulation sleeves (see figure 3.5). To prevent fire, use 600V PVC insulated wire (AWG18) for power and ground wiring (cross sectional area of 0.83mm2 or thicker, anti-galvanic corrosion finish, insulation thickness should be more than 0.8mm, insulation resistance should be more than 50MΩKm at 20°C, approved EN60 320 (VDE0625), and do not remove the transparent cover. Make sure to apply a power switch in the power supply cord with the following characteristics: Others than /P1 model

• rated power current > 1A

• rated rush current > 60A

• fuse(s) of 2A to 15A is (are) necessary.

/P1 model

• rated power current > 3A

• rated rush current > 70A

• fuse(s) of 5A to 15A is (are) necessary.

The power switch and fuse used in the power supply cord should be

• CSA approved (for use in North America)

• VDE approved (for use in Europe).

3.2.3 Input Wiring

1 Make sure the power switch is turned OFF and remove the transparent cover at the

rear of the µR1800.

2 Connect the input wires to the input terminal. 3 Replace the transparent cover.

It is recommended that “crimp on” lugs (for 4mm screws) with insulation sleeves be used for leadwire ends. See figure 3.5.

Figure 3.5 “Crimp on” Lugs

In case of clamped input terminals, do not use “crimp on” lugs.

Since the input terminal will be affected by changes in temperature (e.g. because of wind), make sure to replace the transparent cover after wiring. Even after replacement, take care not to expose the terminals to fans, etc. Suggestions to minimize noise pickup:

• The measuring circuit wiring should be run as remote as possible from the power and ground wires.

• It is recommended that shielded wires be used to minimize noise pickup from an electrostatic induction source. The shielding wire of the cable should be connected to the µR1800 ground terminal (only one ground line).

• To minimize noise from an electromagnetic induction source, twist the measuring line cables in short and equal spaces.

• The to be measured object should be free from noise. However, if it isn’t, make sure the measuring circuit is isolated and the to be measured object is grounded.

WARNING

CAUTION

If TC and RJC is used, the temperature of the input terminals should be as stable as possible. Therefore, make sure to use the transparent cover. The thermal capacity of the wiring should be small (recommended ø ≤ 0.3mm). Refrain from wiring the input parallel. However, if you do, then

• do not use the burnout function

• ground the equipments at the same point

•turning ON/OFF the power might cause malfunction

• RTD cannot be wired parallel.

To prevent an electric shock, ensure the main power supply is turned OFF and connect the ground terminal using a class 3 resistance of 100Ω or less.

If you have an input of DC ≤ 2V or a TC, don’t apply an input voltage exceeding ±10VDC. Do not apply a max. common mode voltage more than 250VAC rms (50/ 60Hz). The recorder and measured values will be adversely affected. Add following to 'CAUTION' This instrument complies with Inatallation Category ll.

NOTE To prevent an emission of electromagnetic disturbances, separate the input wires from

the other wires at least 0.1m. Over 0.5m is recommended.

5.3.6 How to Get a Message Printout

The contents of a message must be entered first. To set or change a message, see 8.2.3. To get a message printed on the chart, proceed as follows: Press the MENU-key and select the ‘MENU=SELECT_FUNCTION’ display using the UP/DOWN-keys. Then press the ENT-key. Select the ‘PRINT_MESSAGE’ display using the UP/DOWN-keys. Press the ENTkey, and select which message you want to print out, since up to five messages can be set. Press the ENT-key and the printing will start. Note that no messages will be printed when the chart speed exceeds 1500 mm/h, in case of the pen model, or 100 mm/h in case of the dot model, or when recording is OFF. When the writing of this printout starts, the display will return to the previous one. When the writing of this printout is finished, the µR1800 returns to the recording previously in progress. You cannot cancel this printout once started.

Messages can be triggered by the keyboard, as described above, and by remote control (option). When several messages are triggered by remote control in a short time, they will be stored in a buffer memory before printing on the chart. It is possible to clear this buffer, which can be useful for example in case the printing will take too much time. When the buffer is full, this will be indicated by an asterisk ( ) in the latest message printout. As a result the next message is lost and will not be printed. To clear the buffer memory, proceed as follows: Press the MENU-key. Select the display ‘MENU=SELECT_FUNCTION’ using the UP/DOWN-keys. Press the ENT-key. Select the display ‘CLEAR_MESSAGE_BUFFER’ using the UP/DOWN-keys. Press the ENT-key. The buffer is cleared. The display will return to the previous one used.

5.3.9 How to Cope with FAIL/Chart End

When equipped with this option and the chart reaches its end or a CPU-error occurs, the output relay will be activated. There is one output relay for Chart end detection, and one for FAIL detection. For the wiring, see 3.2.5.

CHART END:

When there are approx. 2cm left till chart end, the ‘CHT’ indicator will be illuminated in the display and recording will stop. To change the chart, follow the steps as explained in 5.2.1. At the same time the output relay will be activated. This output relay is of the energizing type and this cannot be changed. See also the explanation mentioned below.

FAIL:

When a CPU-error occurs, the output relay will be activated. This relay is of the deenergizing type and this cannot be changed. Therefore this relay will also be activated when the power is off. The activating of this relay will not be shown on the display. See also the explanation mentioned below. When a CPU-error occurs, contact the nearest Sales & Service Office. Addresses may be found on the back cover of this manual.

Chapter 6 HOW TO ENTER SETTINGS

This chapter describes the idea behind the settings of the µR1800 Recorder. It is important to read this chapter carefully before entering or changing settings for the first time.

6.1 Explanation of Modes

To make the operation of the µR1800 Recorder as easy as possible, the operation and setting are broken down into three modes. These are:

Operation Mode:

This mode is for basic operation, which is the operation on a daily basis, excluding settings. It includes operations like recording, chart feed, acknowledging alarms, printing out messages, lists and values. When the power to the µR1800 is turned ON, the recorder will be automatically in the operation mode. The operations within this mode are described in chapter 5.

SET Mode:

This mode will be used when setting parameters must be entered or changed. The parameters include not only settings of range and span, units, alarms, chart speed and clock, but also auxiliary settings which allow you to use the µR1800’s many functions. To enter the SET Mode, press the MENU-key for three seconds. To return to the operation mode, press the MENU-key for three seconds again. The settings of range and span, units, alarms, chart speed and clock are all described in chapter 7. The auxiliary settings (like for example zone recording settings) are all described in chapter 8.

6. HOW TO ENTER SETTINGS

SET UP Mode:

This mode will be used when initial settings must be changed. These settings are entered during the manufacturing of the recorder and seldom need to be changed. These settings include for example alarm relay adjustments, etc. To enter the SET UP Mode, press the ENT-key while turning ON the power. Note that when you are in the SET UP Mode, the recording cannot be ON, and alarms will not be detected. For a detailed overview of the initial settings, see 6.5. For a description on how to perform the settings, see chapter 9.

The following figure shows the structure of modes.

IM 4H3B1-01E

6 - 1

6.2 Concept of Setting Parameters

DISPLAY

The user interface is interactive, which means that you will be asked to enter the necessary data. All data can be entered using the keyboard. When entering data, the functions which are pictured above the actual keys are valid.

The display usually consists of two parts:

SET=RANGE

ESC

to be set parameter

The parameters which need to be entered are shown in black with white letters in this manual. These parameters will flash on the actual display.

In this manual, you can also find another type of display:

01:MODE=

The blank means that the actual display will show your previously set data.

The display ‘*SET OK*’ will appear once all the necessary parameters have been entered succesfully. Pressing the ENT, UP, DOWN or RIGHT-key at those times will result in returning to the beginning of the same flow. Pressing the ESC-key will result in returning to the previous level in the menu.

KEYS

Five keys on the keyboard can be used when entering data:

ESC

PRINT FEED

ALARM

ACK

(The MENU-key is used to enter the SET Mode.) The ESC-key can be used to abort the setting before the ‘*SET OK*’ display appears. The display will return to the previous level in the menu. After the ‘*SET OK*’ display appears, pressing the ESC-key will take you to the beginning of the same setting again.

previously set parameter

ALARM

The UP/DOWN-keys can be used for moving through a menu. In the case of setting e.g.

ACK

messages or units, these keys are used to select alphanumerical characters. UP shows the next choice, DOWN shows the previous choice.

FEED

The RIGHT-key can be used for moving the cursor to the next digit while entering parameters (e.g. in case of 0.000). Since there is no backspace key provided, this key will move to the first digit after the last digit.

NOTE In the case the decimal point is fixed, make sure to enter all digits.

Example: you entered result will be

2. 0.02 (entered value will be placed at last digit)

2.00 2.00

The ENT-key is used for keeping the set parameters. After pressing this key, you will be asked to enter the next parameters.

In the case you entered incorrect data, but haven’t pressed the ENT-key yet, use the UP/ DOWN/RIGHT-keys to correct your error. If you have pressed the ENT-key already, press the ESC-key and enter all necessary data again.

7.2 Alarms (OFF)

7.3 Units (all spaces)

7.4 Chart speed (25 mm/h)

7.5 Clock

The last paragraph (7.6) explains how settings can be copied to other channels.

7.1 How to Set Input Range and Recording Span

One of the following parameters can be set for every channel: SKIP Prevents the specified channel from being measured, recorded and displayed

(7.1.1).

VOLT Measures and records DC-voltage (7.1.2). TC Measures and records temperatures using Thermocouple (7.1.3). RTD Measures and records temperatures using Resistance Temperature Detector

(7.1.3).

DI Accepts Digital Input (contact/voltage level) and performs ON/OFF

recording (7.1.4).

DELT Performs difference computation between two channels which have same

input range (7.1.5).

SCL Performs scaling on voltage, TC and RTD measurements (7.1.6).

Scaling results in appending a different scale to the measured values.

SQRT Takes the square root ( ) of DC-voltage measured data (7.1.7).

7.2 How to Set Alarms

Alarms can be set on the measured data of any channel. If an alarm is set, and an alarm occurs, the ALM indicator will be illuminated and alarm printout will occur. If equipped with the optional alarm output relays, these will be activated by the occurrence of an alarm. Up to four alarm levels can be set per channel. Six types of alarms are available. These are:

H High limit alarm: alarm is generated when the measured value is higher than, or

equal to, the alarm value.

L Low limit alarm: alarm is generated when the measured value is lower than, or

equal to, the alarm value.

R Rate-of-change limit on increase: high alarm is generated when the measured

value variation in the ascending direction during a selected interval is greater than, or equal to, the alarm setting.

r Rate-of-change limit on decrease: low alarm is generated when the measured

value variation in the descending direction during a selected interval is greater than, or equal to, the alarm setting.

Note: the selected interval is determined during rate-of-change alarm set-up. See 9.1.6.

h Difference high-limit alarm: alarm is generated when the difference between the

measured values of two channels is more than the alarm setting. (This type of alarm can only be set when the corresponding channel is of the DELT-type.)

l Difference low-limit alarm: alarm is generated when the difference between the

measured values of two channels is less than the alarm setting. (This type of alarm can only be set when the corresponding channel is of the DELT-type.)

NOTE Alarm settings are automatically canceled on the affected channel, when any of the

following changes occur:

• the input type (VOLT, TC, etc.) or input range (2V, etc.) is changed.

• decimal point for linear scaling and square root is changed.

•minimum or maximum value of the recording span is changed (in case of linear scaling and square root).

•minimum or maximum value of the scale is changed (in case of linear scaling and square root).

Difference alarm settings (h, l) are canceled when any of the following changes occur:

• the reference channel is changed.

• the input type or range of the reference channel is changed.

7.7 How to Set the Remote RJC (For /N5 Model)

When measuring a temperature by thermocouple (TC) and the object of measurement is located at a big distance, it is possible to measure the temperature without using a lot of expensive TC wires by establishing a relay terminal near the measurement object. The relay terminal and object of measurement are connected by TC. The relay terminal and input terminal of the main unit are connected by a compensating copper wire. One other input terminal of the main unit is connected with the relay terminal by TC and by couducting standard setting compensation of the to be measured temperature, which is done by measuring the temperature of the relay terminal, the temperature of the measurement object can be calculated. (Refer to the figure below.)

main unit relay terminal (to be prepared by customer)

TC*

* Please use the same type of TC

NOTES The input mode of the reference channel should be same as the used TC.

The range of each measuring channel will become same as the range of the reference channel. The limits of the span of the measuring channel are the same as for the usual TC input (refer to page 7-4). Scaling is not possible. In case you change the range or input mode of the reference channel, the input mode of the measurement channel being TC will not change, while the span becomes the upper/ lower value of the newly set range.

Trend recording can be done depending on a fixed interval or an interval which depends on the chart speed. Zone recording enables you to define different bands (zones) for each channel, so the recording traces will not overlap. Partial expanded recording enables you to compress a part of the recording range, in order to examine the other part of the range in more detail. Initial values are:

8.1.1 How to Adjust the Trend Recording Format

The µR1800 prints in FIX or AUTO mode. In FIX mode, dot printing is performed with a constant interval regardless of the chart speed (approx. 10s for 6 dot, 15s for 12 dot, 20s for 18 dot and 30s for 24 dot model). AUTO mode is provided to prevent the chart from being damaged during repetitive dot printing. This mode is useful for low chart speeds. The chart is protected from damage because the printout timing changes with the chart speed (approx. 10 to 90 sec).

How to Set the Chart Speed Used When Change-on-alarm or Remote Control is Selected

The following describes the way to use a second chart speed which is activated by remote control or by the occurence of alarms. This function enables you to record data in more detail following a remote control trigger or following the occurence of an alarm. However, to use this second chart speed, it is necessary that your µR1800 is at least equipped with the /R1 option. To be able to use the change-on-alarm function, it is necessary to have alarm output relays installed as well (option /A1, 2 or 3). If your µR1800 is not equipped with the /R1 option, data entry will be ignored. This second chart speed will stay in effect until the remote control status changes back again, or until the alarm turns OFF. The initial value is 25 mm/h.

9.2.1 How to Set the A/D Integration Time

The purpose of the following setting is to specify which A/D integration time will be used. Depending on the power supply, the integration time will affect the ability of noise rejection and therefore the recording.

In case of the pen model

If the power supply of the recorder and of the measuring object are the same, the effect of noise will be automatically minimized and the (initial) value of AUTO is the recommended one. If the power supplies are different, you should select from 50Hz or 60Hz integration time. The choice depends on the power supply of the instrument with the highest noise level. There are three possibilities:

• AUTO: integration time depends on the power supply of the recorder. However, in

case of the /P1 model, the integration time is fixed to 50Hz.

• 50Hz

• 60Hz.

The initial value is ‘AUTO’.

In case of the dot model

The initial value is 100 ms, and this setting should only be changed when required because of specific optional functions. For details, see the option manuals. There are four possibilities:

• AUTO: integration time depends on the power supply of the recorder. However, in

case of the /P1 model, the integration time is fixed to 50Hz.

• 50Hz

• 60Hz

• 100 ms.

The initial value is ‘100 ms’.

9.3.1 How to Select Pen Offset Compensation ON/OFF (Pen Model)

The POC function eliminates deviation (phase difference) between the pens on the time axis. Figure 9.6 shows a side view of the recording status for the 2 pen model (3 & 4 pen models are similar). The initial value is ‘OFF’.

Figure 9.6 Side View of Recording Status

Chart feeding direction

Front of Recorder

Figure 9.6 shows that, in any pen recorder (in order to prevent collision between pens) the pens must be offset by a distance p. Therefore, points recorded at the same time are separated on the time axis. In the case of Pen Offset Compensation, a delay memory is used to store measurement data, equivalent to the time offset p of the pens (other than the reference pen). The pens will start to record these stored data when the chart is fed by the amount of p (time offset).

NOTE Immediately after the recording has been started, only the reference pen operates

normally. The other pens might not seem to operate correctly, but this is due to the time offset. When you stop the recording, the chart will stop and therefore data stored in the delay memory will not be recorded anymore. Therefore, these data will be lost.

Pen Offset Compensation is meaningless for the 1 pen model. Therefore POC setting will be ignored for the 1 pen model. Note that an asterisk will be printed in the periodic printout when POC is ‘ON’.

9.5 How to Select the Type of Bargraph

The µR1800 can display two types of bargraphs:

1) Left-referenced (%) bargraph (NORML)

1 2

The left side of the bargraph represents the left span value, the right side of the bargraph represents the right span value. The display will show the measured value as a percentage of the span.

2) Center-zero bargraph (CENTR)

1 2

The center of the bargraph represents the center value of the span. The left side and the right side of the bargraph represent the left and right span values respectively. This bargraph will display the deviation between the actual measured value and the center of span.

The type of bargraph can be selected for each channel individually. The initial value for all channels is left-referenced bargraph (NORML).

SETTING PROCEDURE:

Enter the SET UP Mode by turning ‘ON’ the power while pressing and holding the ENT-key until the SET UP display appears.

Use the UP/DOWN-keys to select the display ‘SETUP=BAR’. Press the ENT-key.

Select the channel No. for which you want to change the type of bargraph. Press the ENT-key.

Select ‘NORML’ (for the left-referenced bargraph) or ‘CENTR’ (for the center-zero bargraph) using the UP/DOWN-keys. Press the ENT-key. The display ‘*BAR SET*’ will appear.

This setting has been completed, but has not been stored yet. Press the ENT-key to set the bargraph for other channels or press the ESC-key to adjust other settings in the SET UP Mode.

Before leaving the SET UP Mode, you have to store your new settings. Press the ESCkey to return to the ‘SETUP=BAR’ display and then select the ‘SETUP=END’ display. Press the ENT-key. Select ‘END=STORE’ to keep your new settings or ‘END=ABORT’ and press the ENT-key. After a few seconds, the Operation Mode will appear.

NOTE The bargraph has the same resolution as the data shown on the display. By adding/

deleting a digit of the displayed data (done during setting of the recording span), you can affect the resolution of the bargraph. The maximum resolution is 1% (100 steps).
