Power Supply Wiring

Wiring

Preparation

WARNING

• To prevent an electric shock, ensure the main power supply is turned off before

wiring.

• To prevent fire, use 600 V PVC insulated wire (AWG18) for power and ground

wiring (cross sectional area of 0.83 mm2 or thicker, anti-galvanic corrosion finish,
insulation thickness should be more than 0.8 mm, insulation resistance ahould
be more than 50 M Km at 20˚C, approved EN60 320 (VDE0625) ), or
equivalent cables.

• Connect the protective grounding wire to the earth through grounding resistance

less than 100 before turning on the power .

• Use crimp on lugs (for 4 mm screws) with insulation sleeves.

• To prevent an electric shock, cover the power terminals certainly with the

transparent cover.

• Make sure to apply a power switch with the following characteristic:

rated power current > 1A
rated rush current > 60A
fuse(s) of 2 to 15A

Wiring method

1 The rated power supply voltage for the recorder is 100 to 240 V AC.
2 Turn the recorder’s power switch OFF.
3 Open the transparent cover of the power terminal after releasing the cover screw.
4 Connect the power supply wires and the protective ground wire to the terminal. To

prevent an emission of electromagnetic disturbances, separate the input wires from
the other wires at least 0.1 m. Over 0.5 m is recommended.

5 Cover the terminals with the transparent cover, and secure the screw.

Power Supply Wiring

LN

Functional earthing cord

Power supply wires

Note

• Do not apply a power supply in the range from 132 V to 180 V AC. Doing so might affect the
measuring accuracy.

• To prevent emission of electromagnetic disturbances, separate the power supply wires from the
other wires at least 0.1 m. Over 0.5 m is recommended.

Input Signal Wiring

WARNING

To prevent an electric shock, ensure the main power switch is turned off when wiring.

CAUTION

Do not apply inputs exceeding the rated range as follows to prevent the recorder

from damage:

• Maximum input voltage
±10 V DC for TC, and for the voltage range of 2 V DC or less
±30 V DC for the voltage range of 6 to 20 V DC

• Maximum common mode voltage
250 V AC rms (50/60 Hz)

• This instrument complies with Installation Category II.

1 Turn off the recorder power switch.
2 Remove the transparent cover for the input signal terminals.
3 Connect the input signal wires to the terminals. To prevent an emission of electro-

magnetic disturbances, separate the input wires from the other wires at least 0.1 m.
Over 0.5 m is recommended.

4 Attach the cover on the terminals, and secure the screws.

It is recommended to use the crimp-on lugs (for 4 mm screws) with insulation sleeves for
lead wire ends, but they are not required for thermocouples (TC) .

Crimp-On Lugs

Suggestions to minimize noise pickup:

• Separate the measuring-signal wires from power lines and grounding lines.

• It is desirable that the measuring object is not a noise source; if not, insulate it from

the measuring signal wires and ground the object.

• It is recommended to use shielded wires to minimize noise pickup from an electro­static induction source. The shields are connected to the recorder’s grounding
terminal, if necessary. In that case, avoid two-point grounding.

• To minimize the noize from an electrostatic induction noise, twist the measuring
wires (a pair of wires) in short and equal intervals.

• The grounding line must have low resistance.

1-12

1

Wiring

For TC (thermocouple) inputs the ambient temperature around the recorder’s terminal
board should be kept as stable as possible.

• Cover the input terminals with the transparent cover.

• Do not use a large-diameter wire (cross sectional area of more than 0.5 mm

because it has a large radiation rate.

• Keep the ambient temperature as stable as possible; start/stop of a nearby fan can
considerably affect the temperature.

If input signal wires are connected to two or more receivers with parallel connection,
measured values sometimes affect each other. The following notes should be observed
for parallel connection:

• Ground each receiver at the same point.

• Do not turn on/off the power of a receiver while other receivers are in measuring

operation.

• A resistance temperature sensor (RTD) cannot be used essentially in parallel
connection.

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

4 Cover the terminals with the transparent cover and secure the screws.

Note

• Use shielded cables for remote control signals to prevent noise pickup. The shield should be
grounded at the recorder’s terminal.

Setting 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 .
VOLT Measures and records DC-voltage.
TC Measures and records temperatures using Thermocouple.
RTD Measures and records temperatures using Resistance Temperature Detector .
SCL Performs scaling on voltage measurements.

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

Restrictions apply to the measurable types of input depending on the type of recorder
used. Check your recorder type as indicated on the nameplate (see Section 1.3 for
details on the nameplate), and then refer to the following table:

Model Code Measurable Type of Input
RD260 Voltage (VOLT), thermocouple (TC), SCL
RD266-RTD Resistance temperature detector (RTD, dot–models only)

3.4 Selecting A/D Integration Time (Pen Model)

Setting 50-60Hz 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.
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. AUTO is the
initial value.

• 50 Hz.

• 60 Hz.

This paragraph describes the way to change default settings for REMOTE operation.
The settings concerning the REMOTE option are always accessible, and data entry will
be ignored if your instrument is not equipped with this option.

The -R option allows you to execute functions on this instrument by a remote trigger
(contact input).
The functions which can be executed by a remote trigger are:

• start/stop the recording

• change the chart speed to a preset second chart speed

However, the -R terminal has only two terminals, which means that only two functions
can be triggered.
Initially the functions are assigned to the terminals as follows:
1: start/stop the recording [RCD] (Record)
2: change the chart speed to a preset second chart speed [C_Spd] (Chart Speed)

Chapter 4 Calibration and Adjustment

4.1 Calibration

Calibration is a comparing operation between standard inputs and measured values.
It is recommended to carry out a calibration once a year to assure the measuring
accuracy.

Required Instruments

The instruments for calibration should have the required resolution. If necessary, ask the
sales office from whom you purchased the recorder about those instruments.
Required instruments:

DC voltage standard
Decade resistance box

Calibration Connections

1. Connect the instruments to the recorder; connecting the terminals is shown below.

Give enough warm-up time to the instruments (more than 30 minutes for the recorder).

Reference Junction Compensation for Thermocouple Input

A DC voltage generated by a thermocouple differs from a value calculated from the table
of thermo-electromotive force (EMF) because the table is based on the 0˚C reference
temperature but the temperature at the recorder input terminal is generally equal to the
room temperature.
The recorder measures the temperature at the input terminal for compensation; when the
input terminals are shorted (equivalent to 0˚C of the thermocouple in the EMF table), the
recorder indicates the temperature at the input terminal.
For calibrating a recorder, an input voltage after the compensation (after subtraction of
the compensating voltage) should be applied to the recorder.
