3. Input terminal(1) The maximum allowable inputs of the input terminal shall be as follows. Be careful not to apply
input exceeding these values. An incorrect application causes the product to fail or results insignificant degradation or misoperation.
- Thermocouple, voltage mV, voltage V: ±20 volts or less- Current mA:±30 mA or less, or ±7.5 volts or less(2) The parallel connection of the input is not allowed. Inobservance causes measurement errors
and unstable control, thereby leading to non-conformity in the system as a whole.
(3) For the thermocouple, establish connection up to the product's input terminal using thethermocouple or compensating wire.
(4) For the resistance thermodetector, be sure to use the cords having the same resistance value toprevent measurement error. Note that the burnout detector is not provided with the four-wiresystem.
(5) When connecting the protection element such as Zener barrier for input protection, large
measurement errors may occur.
Be sure to check the combination of protection elements and fully observe the product's
specifications values of allowable signal source resistance and allowable wiring resistance.
4. Output terminal(1) Use the output terminals within the rated range. Connecting a load out of the rated range leads toa failed product, significant degradation or misoperation.
5. Alarm terminal(1) Use the alarm terminal within the rated range. Applying a load out of the rated range leads to afailed product, significant degradation or misoperation.
(2) Be sure to connect a load with the alarm terminal through the buffer relay. In addition, be sure toprovide the buffer relay coil side with a contact protection element in order to protect the productinternal relay contact and reduce noise.
6. Optional terminal(1) Use the optional terminals within the rated range. Applying a load out of the rated range leads toa failed product, significant degradation or misoperation.

Caution(1) Establishing a connection with a power supply out of the rated range leads
to a failed product, significant degradation or misoperation.
(2) Applying overcurrent or over voltage to the input/output terminal of the unit
leads to a failed product, significant degradation or misoperation.

4-3-3. Example of wire connection
1. Example of contact input wire connection

As shown in the left figure,approx. 5V/2 mA is applied
to the switch.
Be careful about the contact
capacity.
[Unit]
The contact inputs start to operate by establishing a short circuit between the designated terminal
and the common (COM) terminal. Although it is common to use the switch or relay, the contact
inputs can be operated with open collector output signals from the peripheral equipment.

-13-

4-3-4. Wire connection precaution

Warning

For preventing serious accident, be sure to read and understand the following
instructions.

1. Wire connection shall be performed by a specialist.
Wire connection shall be performed by a worker having the basic knowledge of instrumentation andoperational experience.
2. Attaching the terminal cover
After the completion of wire connection, take measures for safety so that the user cannot touch theunit terminals directly.
The dedicated terminal cover is prepared as an accessory (optional).
3. Separating from intense electric circuit and noise source
Do not install the product near the equipment that serves as a noise source (such as magnet relay,
motor, thyristor regulator, inverter) to avoid adverse effect due to noise. Separate the wiring of the
product from that of these devices without installing in the same duct.
Take measures against noise as needed.
4. Be careful about the ground terminal connection.
Good-quality grounding (earth) is of importance in ensuring reliability of the end product as a whole.
Generally, it is desirable that each device is connected with a single point grounding. The product isprone to noise in the case of separate grounding. Extra case must be exercised with the grounding
route.
5. Separating from heat sources
Do not install the product near any heat sources in order to avoid adverse effect due to hightemperature. A heat source near the product may cause measurement errors or eventually shorten
its life. Be careful about the ambient temperature of the product.
If the product is installed in a place exposed to wind or sharp change in ambient temperature,measurement errors will occur. Avoid such ambient environment.
6. Unused terminal
Do not connect anything to unused terminals. Failure to observe this causes malfunction.
7. Measures against incorrect output at turn-on
When the power is turned on, output-related signals are output instantaneously in some cases
before the product starts correctly.
Take measures using an external circuit as needed.

10-2. Analog output
There are two analog outputs and both the output signals are 4 to 20 mA DC. Scaling setting ispossible for each data (CP, temperature, EMF, CO, CO2 or DP) in a specified range. (For example,
a temperature range of 0 to 1200C is output at 4 to 20 mA, and 700 to 1000C at 4 to 20 mA.)
For the analog 1st output, the CP value is output as an analog signal. Specify the range of CP
value to be output at 4 to 20 mA DC as the setting item.
For the analog 2nd output, EMF, temperature, CO, CO2 or DP is selected and output. This selection
is independent from the items to be displayed in the lower-row indicator.
The computed result can be output by analog signal output in MODE12 "analog output manual
output" when AUTO is selected. (Manual output value is output when MANUAL is selected.)

10-3. Contact input
1. Sensor is burnout
During signal input (continuity), the BURN lamp is turned on and sensor impedance autocheck andtrigger output are discontinued.

2. CO concentration external input availability
During signal input (continuity), the EXT lamp lights up. When the following conditions (1) to (3) are
met, an external analog-input value is selected as the CO value.
(1) During signal input (continuity)(2) Er4 is not developed.
(3) The CO input value falls within the range preset in MODE5 "CO input normal range upper andlower limits".

3. Computation output hold
During signal input (continuity), the computation and display output value of CP, CO2 and DP are
held. However, the temperature, CO concentration and EMF will not be held.
In the case of signal input (continuity) during first-order lag computation, the output value will be held
after stabilization.

10-4. EMF correction
The measured O2 input (EMF) can be corrected with the predetermined compensation formula. The
correction parameters for Ka, Kb, and A used in EMF correction computation are calculated in
automatic correction processing. However, processing of EMF correction function will not be
implemented during impedance check.
This function is started manually by the customer. Although normal functions are suspended during
this operation, CP and TEMP (CO, EMF) outputs are displayed as in the case with normal mode.
(Outputs are retained during data fetch and write.)
There are three different correction values - CP value, CO2 value, DP value. Select any one of thevalues in advance and input the value from the correction value data selection of the selected
system data. The one-point (span) and two-point (span and zero) correction methods are available.

1. Correction procedures(1) For one-point correction (such as continuous furnace)
It is effective to implement automatic correction with the workpiece inserted before opening thefurnace door.
Example of chartTime
It is better to implement
correction before opening thefurnace door.

Determine the value to be employed for correction data in the MODE2 "correction data selection" screen
and input the adopted value to the CP calculators.
Perform measurement on other instruments (resistance equation CP instrument, CO2 instrument, DP
instrument).

When performing automatic correction (A point) during measurement on other instruments, span data iscaptured to the CP calculators from the MODE2 "first data fetch command" screen.

On the MODE3 "present first EMF/temperature" and "present first CO/measured value” screens, check the
span data captured to the CP calculators for normality. If the values are not normal, capture the span data
to the CP calculators from the MODE2 "first data fetch command" screen again.

On the MODE3 "present first CO/measured value" screen, input other measured values to the values
employed for correction data.

Start automatic correction on the MODE2 "automatic correction operation start command" screen.

-39-

(2) For two-point correction (such as continuous furnace)
It is effective to employ this method in a continuous furnace in which the settings are changed ina wide range (0.3% C or more)
Example of chartTime

B: It is better to implement
correction after a lapse of 1 houror more after the setting isreached.
A: It is better to implement
correction after a lapse of 1 houror more after the setting isreached.

Determine the value to be employed for correction data in the MODE2 "correction data selection" screen
and input the adopted value to the CP calculators.

Perform measurement on other instruments (resistance equation CP instrument, CO2 instrument, DP
instrument) under the highest CP value conditions among the operation conditions.

When performing automatic correction (A point) during measurement on other instruments, span data iscaptured to the CP calculators from the MODE2 "first data fetch command" screen.

On the MODE3 "present first EMF/temperature" and "present first CO/measured value” screens, check the
span data captured to the CP calculators for normality. If the values are not normal, capture the span data
to the CP calculators from the MODE2 "first data fetch command" screen again.

On the MODE3 "present first CO/measured value" screen, input other measured values to the values
employed for correction data.

When performing automatic correction (B point) during measurement on other instruments under thelowest CP value conditions among the operation conditions, capture the zero data into the CP calculatorsfrom the MODE2 "second data fetch command" screen.

On the MODE3 "present second EMF/temperature" and "present second CO/measured value" screens,check the span data captured to the CP calculators for normality. If the values are not normal, capture thespan data to the CP calculators from the MODE2 "second data fetch command" screen again.

On the MODE3 "present second CO/measured value" screen, input other measured values to the values
employed for correction data.

Start automatic correction on the MODE2 "automatic correction operation start command" screen.

-40-

2. Abnormality judgment of Ka, Kb, and A
Determine whether the calculated Ka, Kb, and A fall within the range of preset upper and lower limits.
If the calculated values fall outside this range, determine the abnormality in the CP correction value.
Perform successive CP computation using the previous correction value.
In the case of abnormality in the CP correction value, abnormal state is maintained until error code
display (Er8) and alarm output (AL1) are performed and MODE1 "sensor abnormal reset" operation is
implemented, or a new correction operation is performed and a normal value is obtained.

10-5. Input average filter
Input average filter computation can be performed with respect to each input of temperature, CO,and EMF.

The computing equation is as follows.

Where
X [n]: value before input average filter computation
Y [n]: Value after input average filter computation
N: Number of input average filters (Set in MODE0 "number of input average filters")

10-6. Temperature moving average
For temperature input, temperature moving average computation can be performed in addition to
input average filter computation.

Buffering

Moving averagecomputation

1 Temperature buffering is implemented once every minute. Moving average computation is
performed with the buffered temperature. The computing equation is as follows.

Where,
Y [m]: temperature after input average filter computation
Z[m]: temperature after temperature moving average computation
M: temperature moving average time
When the temperature moving average is valid, the temperature changes every minute. Whenm=0, the temperature moving average function is disabled.

10-7. Customer scale adjustment
This product is provided with the customer scale adjustment function in mode 12. The customer
can perform scale adjustment as long as a high-precision voltage current generator, a digital
multimeter, a dial resistor are prepared.

10-7-1. Overview
This function allows the user to perform scale adjustment of the following input/output
functions.
▪ Analog 1st output▪ Analog 2nd output

10-7-2. Concept of scale adjustment
Scale adjustment is implemented with internal computation processing based on the following
equation [Y=aX+ b] using two correction values as constants - zero correction value(equivalent to b) and span correction value (equivalent to a).

Measured value

a: factor of sample linear
Sample linear

Ideal linear

b: shift of sample linear

Output value equivalent to 4 mA

Output value equivalent to 20 mA

Output value
The ideal linear is a straight line having no measurement errors. When "output value
equivalent to 4 mA" is output, 4 mA is output. When “output value equivalent to 20 mA" isoutput, 20 mA is output.
Thus, Y=X because there are no correction values.
The sample linear is shifted to + side by around 4 mA and its inclination is smaller incomparison with the ideal linear.
For example, when "output value equivalent to 4 mA" is output, 4.04 mA is output. When
"output value equivalent to 20 mA" is output, 20.02 mA is output.
Thus, output deviation can be eliminated by adding a bias (b) equivalent to -0.04 mA andmultiplying a factor (a) to increase the inclination.

10-7-3. Output-related scale adjustment
Explanation of the procedures for adjusting the output-related (analog output) scale is asfollows.
1. Preparation for measurement-related device
Input to be adjusted

2. Wire connection(Unit)(digital multimeter)* The terminal number
varies depending on thetype.
[Analog output]
3. Scale adjustment(1) Preparation and energization▪ Set the environment conditions of this product to the "reference operating conditions" forensuring stability.
▪ After checking the wire connection, energize the product and measurement-related device toensure stability.
(2) Output check before adjustment▪ Carry out output checks before adjustment (3 places) with the following as a guide.
Minimum value: 4 mA
(output value: 0%)

Median value: 12 mA(output value: 50%)

Maximum value: 20 mA(output value:100%)

Output check before
adjustment
Output check after
adjustment(3) Setting of shift correction value▪ Set the output to 0%.
▪ When the minimum value is higher than the ideal value by 4 mA or more, set a negativevalue for the shift correction value. If not, set a positive value for the shift correction value.
▪ For the shift correction value, set a value equivalent to the ideal value while checking thedigital multimeter.
(4) Setting of range correction value▪ Output value: Output 100%.
▪ When the maximum value is higher than the ideal value by 20 mA or more, set a range
correction value of 1.0 or smaller. If not, set a range correction value of 1.0 or larger.
▪ For the range correction value, set a value equivalent to the ideal value while checking thedigital multimeter.
(5) Readjustment▪ Repeat adjustment specified in steps (3) and (4) for a few times until the output value falls
within the allowable range.
(6) Instruction check after adjustment▪ Carry out output checks after adjustment (3 places) as in the case with the checks before
adjustment and make sure there aren't any problems.

-43-11. Trouble shooting
