2.2.2 Power Supply Wiring

(1) The rated power supply voltage for the recorder is follows.

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

Power Supply Wiring

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

WARNING

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 should 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 near by with the following characteristic:

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

Protective grounding wire

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 an emission of electromagnetic disturbances, separate the power

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

2 - 5

2.2.3 Input Signal Wiring

(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.
(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.

!

WARNING

CAUTION

In case of using a thermocouple (TC), the recorder is equipped with a reference junction
compensator, so 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 mm2) because

it has a large radiation rate.

• Keep the ambient temperature as stable as possible; start/stop of a nearby fan affects
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 detector (RTD) cannot be used essentially in parallel
connection.

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

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)

• The installation of each input is Category II.

NOTE • 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.

4.8.5 Calibration

Shaft

4 - 13

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 for calibration

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

Recommended instruments

OMEGA model # CL511 calibrator

Calibration procedure

(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).

(2) Check that the ambient temperature and humidity are within the standard operating

conditions.

Standard operating conditions

Ambient temperature : 23±2˚C
Humidity : 55±10% RH
Power supply : 90 to 132 V AC, or 180 to 250 V AC
Power frequency : 50/60 Hz±0.1%
Warm-up time : 30 minutes or more

Mechanical vibration : Within the range not affecting recorder operation
However, when the calibration is conducted under normal operating conditions (see subsection 4.8.6),
check the accuracy influenced by the conditions.
Chart paper yields thermal expansion or shrinkage, sometimes resulting in differences from the
calibrated values.
Examples of expansion are shown below assuming the reference temperature 20˚C and humidity 65% RH:

Expansion at 85% RH..... 0.4% or less

Expansion at 35% RH..... 0.45% or less

(3) Input the standard signals equivalent to 0, 50, and 100% of the setting range of the

recorder, then check the difference error between input signals and measured
values.
If the error is not within the specified accuracy, contact OMEGA Engineering.

NOTE A reference input for a thermocouple (TC) signal needs temperature

compensation; the temperature at the recorder input terminal should be
measured to make voltage compensation (adding) due to the reference junction
temperature compensation.

Reference Junction Compensation for Thermocouple Input

A DC voltage generated by a thermocouple differs from a value calculated from the table of thermo­electromotive 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; an example is shown in (thTRCIII reference junction compensator
is used).

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

Recorder as Viewed from the Side

This figure 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

7.16 Changing Default Settings for REMOTE Operation (option)

This paragraph describes the way to change default settings for REMOTE operation.

NOTE The settings concerning the REMOTE option (/R1) are always accessible, and

data entry will be ignored if your instrument is not equipped with this option.

The /R1 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

• have messages printed out (up to five messages)

However, the /R1 terminal has only five terminals, which means that only five functions
can be triggered. The printing out of one message takes up one terminal.
Initially the functions are assigned to the terminals as follows:
1: start/stop the recording [ ] (Record)
2: change the chart speed to a preset second chart speed [ ] (Chart Speed)
3: have message 1 printed out [ ] (Message 1)
4: have message 2 printed out [ ] (Message 2)
5: have message 3 printed out [ ] (Message 3)

The purpose of this setting is to assign the to be triggered functions to the five terminals.

SETTING PROCEDURE:
Enter the SET UP mode by turning ‘ON’ the power while pressing and holding the [CH
UP] ( ENT) key until the SET UP display appears.

Use the [ ] key to select the display [ ]. Press the [ENT] key.

Use the [ ] key to select the terminal No. ([ ] to [ ]) ( /R1 has five
terminals.) Press the [ENT] key.

Use the [ ] key to select the function which you want to assign to that terminal. You
can choose from [ ] (start/stop recording), [ ] (second chart speed),

[ ] to [ ] (message No. 1, 2, 3, 4, 5). Press the [ENT] key. The display
[ ] appears.

Before leaving the SET UP mode, you have to store your new settings. Use the [ ] key
to select the [ ] display, and press the [ENT] key.
Select [ ] to keep your new settings or [ ] to abort the settings, and
press the [ENT] key. After a few seconds, the OPERATION mode will appear.

NOTE If you select ‘start/stop recording,’ recording stops if the remote input terminal

is open and starts if the terminal is closed. If you press the [RCD] key during
the startup of remote-controlled recording, recording stops. In contrast, if you
press the [RCD] key during the shutdown of remote-controlled recording,
recording starts. You can start/stop remote-controlled recording even during
the start/stop sequence of recording based on the [RCD] key.
