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

• Lateral tilting: 0 to 10 degrees

• Longitudinal tilting: Forward tilting: 0 degrees

Backward tilting: 0 to 30 degrees

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.

(2)Connection to Power Terminals

For the connection to power terminals, use a 600 V vinyl insulated cord (Note 2) with the crimp style terminals and an insulation sleeve. Note 2: Use the cords approved by the following

standards.

1) IEC 60227-3

2) ANSI/UL817

3) CSA C22.2 No. 21/No. 49

Be Careful with the Power

The power voltage of this product is indicated beside the power terminals. Avoid applying any voltage other than indicated, otherwise a serious accident occurs or malfunction results. In addition, if noises are mixed into the power, take a remedial measure, such as the addition of a noise cut transformer, etc.

These are indications according to CSA Standard, Canada. L is for single-phase AC power, and N is for neutral. To secure the performance of this instrument, connect the terminals appropriately.

4.4 Measuring Input 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).

5. For this connection, use a cable with a crimp style terminal with

an insulation sleeve for the input terminal.

(2) Connection of DC Voltage (Current) Input

Use a twisted cable for instrumentation as the input cable for suppressing noises. For the current input (optional), mount a shunt resistor for current input (Refer to 8.1 Shunt Resister for Current Input) to the channel to be measured before connections. Avoid using this instrument in parallel with other instruments, otherwise troubles may occur (Indication fluctuation, indication errors, and others may occur.).

(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).

(4) Connection of Resistance Thermometer (RTD)

For preventing measuring errors, use a 3-core code of which each wire has equal resistance value. Avoid using one resistance thermometer in parallel with other instruments (controllers, etc.).

• Resistance thermometer (RTD) input

3-core cord

(Same diameter and length)

Note: The resistance value for one code is

Resistance thermometer

123456

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.
