Main features and functions

Besides measuring temperature and various industrial quantities of multi channels and displaying real

time trends, bar graphs, numeric values, etc. in various formats on 12.1 inch TFT color LCD, this recorder

can store data into the internal memory or a memory card (a CF card) and replay them if required.

Stored data can be used using commercial software like EXCEL, etc.

feeling

Marker function

The monitoring of measurement results is easy since the data are displayed on various formats of screens. The previous data stored in the CF card can be read and the stored data can be managed using commercial software like EXCEL (Registered trademark of Microsoft Corporation), etc.

(Planning to get CE marking compliance)

Real time trends, bar graphs, data (in a table format) and combined displays of “real time trends and bar graphs”, “real time trends and numeric values” and “real time trends and historical trends” can be arbitrarily selected and monitored with most suitable screens to meet your requirements. As alarm display screen displaying past alarm activation status collectively and a marker list screen are also available. In addition, up to 6 groups can be registered. With easy operation, these screens can be switched and 4 separate screens can be displayed.

Start/stop of data storage can be executed by arbitrary condition settings like key operation, alarm settings, time settings, etc. and the simultaneous storage to maximum 6 files can also be executed. In normal operations, data are stored into the internal memory and can be saved on the CF memory card.

As the trend screen displays data on a chart with scale plates and pointers, the data can be monitored like an analog recorder.

Markers and marker texts (alphanumeric characters, maximum 30 characters) can be written on the trend screen. A marker text is written arbitrarily, and also 50 types of marker texts can be registered in advance and these marker texts can be written with key operations. The marker texts can be written on the historical trend screen (replay), too. Markings only without marker texts are also available.

MODBUS

communication

Consumables not

required

Easy setup

Parameter settings, data acquisition and operation can be executed with the optional high order communication. As the communication protocol utilizes MODBUS, this recorder can communicate with a program indicator equipped with the MODBUS protocol without creating any communication software and the configuration of a system is easy. (MODBUS: The registered trademark of Schneider Electric SA)

Since consumables like charts, pens and inks as used in recorders are not required, this recorder is clean and less time consuming.

The easy interactive parameter setting offers parameter settings by selecting a setting item from the menu screen with key or touch-panel operation and then by opening a window. Also the operation can be executed easily with the required parameter settings on the ”Simple settings (HOME)” screen.

5.2 Precautions for connections



Observe the following cautions during connections for securing safety and reliability.

(1) Power supply

Use a single-phase power supply having a stable voltage without any waveform distortion for the purpose of preventing wrong operations.

(1) A switch and an overcurrent protective

device

Prepare a switch and an overcurrent protective device (3A) to the power supply for preventing an electric shock accident during connection work. This recorder is not provided with any replaceable fuse.

(2) Turn off the power supply before

connections.

Be sure to turn off the power supply before connecting cables to the power and the input/output terminals to

Warning

event an electric shock.

(2) Keep the input/output connections away

from a high voltage power circuit

Don’t place the input/output cables close or in parallel with any strong power circuits including power line. Place the cables 50 cm or more away from high voltage power circuits when they are placed close or in parallel to other circuits.

(3) Keep the thermocouple input away from

a heat source

For thermocouple inputs, keep the input terminals

away from a heat source (a heating body) to reduce a reference junction compensation error. Don’t expose the input terminals to direct sunlight, etc.



(4) Keep all connection cables away from

noises

Keep all connection cables away from noise source as far as possible, otherwise unexpected malfunction may occur. Provide a solution if the cables cannot be separated from a noise source due to unavoidable circumstances.

Major noise

Remedial

measures



 Electromagnetic switch, etc.  Power line having waveform distortion  Inverter  Thyristor regulator

Insert noise filters between power terminals and input/output terminals. A CR filter is often used.

(5) Use crimp style terminals

(1) Fix crimp style terminals to termination of

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

(2) Use the crimp style terminals with insulation

sleeve for preventing an electric shock.



(6) Unused terminals

Don’t use any unused terminals for relaying; otherwise the electric circuits may be damaged.



Secure the connected cables properly.

Secure the connected cables so as not to allow them to be hooked by a person or a substance, otherwise the connections may be cut and disrupted that may cause an electric shock or other accidents.

A high voltage may be applied to the measuring input terminals due to common mode noises. The allowable noise value is lower than 30 V AC or lower than 60 V DC. Make sure that the noises are lower than the allowable values. Mount the terminal cover after connections for the purpose of preventing an electric shock and to protect the input wires. In the case of thermocouple input, the mounting of the terminal cover can reduce the reference junction compensation error.

(3) Connections of thermocouple (TC) inputs

Be sure to use thermocouple wires (or extension wires) to the input terminals of this recorder. If a copper wire is used halfway, a noticeable measuring error occurs. Don’t use a pair of thermocouple wires in parallel with other instruments (controller, etc.), otherwise a malfunction may occur.

relay is broken, if a signal exceeding the contact rating is applied even if momentarily.

 To prevent a malfunction being caused by a light load, the most effective

mounting position for the element is on the coil side of the buffer relay ('a'

in the connection diagrams under (2) on 5.5)

(1) Coil rating ........... Less than the contact rating of output terminals

(2) Contact rating ....... More than twice the load current

A coil surge absorption element built-in type relay is recommendable. Mount an additional buffer relay if a buffer relay satisfying the load rating is not available.

Mount a contact protective element if a surge absorption element built-in buffer relay is not available. This element is generally composed of C (capacitor) and R (resistor).

<Reference values of C•R> C : 0.01 µF (Rating about 1 kV) R :100 to 150 Ω (Rating about 1 W)
