• Use a solderless terminal with an insulation sleeve in which the M3 screw fits whenwiring the AER-102-ECL.
• The terminal block of this instrument is designed to be wired from the left side. The
lead wire must be inserted from the left side of the terminal, and fastened with theterminal screw.
• Tighten the terminal screw using the specified torque. If excessive force is applied tothe screw when tightening, the terminal screw or the case may be damaged.
• This instrument does not have a built-in power switch, circuit breaker and fuse.
It is necessary to install a power switch, circuit breaker and fuse near the instrument.
(Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2 A)
• For a 24 V AC/DC power source, do not confuse polarity when using direct current(DC).
• Be sure to connect the ground terminal to earth for safety (D-class grounding).
Keep the grounding of this unit separate from other electrical devices, such as motors.
• Do not apply a commercial power source to the sensor which is connected to the input
terminal nor allow the power source to come into contact with the sensor.
• Use the 2-electrode Conductivity Sensor in accordance with the sensor input
specifications of the AER-102-ECL.
• Keep the input wires and power lines separate.
4Note about 2-Electrode Conductivity Sensor Cable
The 2-electrode Conductivity Sensor cable is a highly-insulated (electrical) cable.
Please handle it with utmost care as follows.
• Do not allow terminals and socket of the 2-electrode Conductivity Sensor cable tocome in contact with moisture or oil of any kind. Likewise, ensure fingers are clean,
otherwise the insulation will deteriorate, resulting in unstable indication.
Be sure to keep the cable dry and clean at all times.
If the cable is stained, clean it with alcohol, and dry it completely.
• For calibration or electrode checking/replacement, the 2-electrode Conductivity Sensor
cable should be wired with sufficient length.
• Keep the 2-electrode Conductivity Sensor cable and junction cable away fromelectrical devices, such as motors or their power lines from which inductive interference
emanates.

• Setting range: 1 to 120• Conductivity (Temperature) Filter Time Constant
Even when conductivity (temperature) measured value before filter process changes
as shown in (Fig. 7.3-1), if the filter time constant “T” is set, the conductivity(temperature) measured value changes as shown in (Fig. 7.3-2) so that conductivity(temperature) measured value after finishing filter process can reach 63% (of thedesired value) after T seconds have passed. If the filter time constant is set too large,
it affects EVT action due to the delay of response.
(e.g.) In case the LSD (least significant digit) of the conductivity (temperature) measured
value prior to filter process is fluctuating, it can be suppressed by using the filter
time constant.

When a sensor cannot be set at the exact location where measurement is desired,
the resulting measured temperature may deviate from the temperature in the desired
location. In this case, the desired temperature can be set for the desired location by
setting a temperature calibration value. However, it is only effective within the input
rated range regardless of the temperature calibration value.
Temperature after calibration = Current temperature + (Temperature calibration value)(e.g.) When current temperature is 23.5 ,If temperature calibration value is set to 1.5 : 23.5 + (1.5) = 25.0

EVT output status can be read by reading Status flag 2 (EVT1, EVT2, EVT3, EVT4
output flag bit) in Serial communication (C5 option).
EVT output status, when input errors occur, differs depending on the selection in [EVT
output when input errors occur (p.41)].
• If(Disabled) is selected, EVT output will be turned OFF when input errors occur.
• If(Enabled) is selected, EVT output will be maintained when input errors occur.
9.3 Error Output
If(Error output) is selected in [EVT1 type (p.27)], and when the error type is“Error” in (Table 9.5-1), the EVT1 output is turned ON.
The same applies to EVT2, EVT3 and EVT4.

If(Fail output) is selected in [EVT1 type (p.27)], and when the error type is“Fail” in (Table 9.5-1), the EVT1 output is turned ON.
The same applies to EVT2, EVT3 and EVT4.
9.5 Conductivity Input Error Alarm
Conductivity input error alarm is used for detecting actuator trouble.
Even if conductivity input error alarm time has elapsed, and if conductivity input does
not become higher than conductivity input error alarm band, the unit assumes that
actuator trouble has occurred, and sets Status flag 2 (EVT1, EVT2, EVT3, EVT4 output
flag bit).
In Serial communication, status can be read by reading Status flag 2 (EVT1, EVT2,
EVT3, EVT4 output flag bit).
If(Conductivity input error alarm output) is selected in [EVT1 type (p.27)], theEVT1 output is turned ON.
The same applies to EVT2, EVT3 and EVT4.
Conductivity input error alarm is disabled in the following cases.

If(Lock 3) is selected in [Set value lock (p.36)], the unit can
not proceed to Conductivity Calibration mode.
In Conductivity Zero adjustment, adjustment is performed
so that conductivity becomes 0 (zero), without immersing
the 2-electrode Conductivity Sensor in the standard
solution.
In Conductivity Span adjustment, the 2-electrodeConductivity Sensor is immersed in the standard solution,
and adjustment is performed, while checking conductivity.
However, it is only effective within the measurement range
regardless of the adjusted value.
When a sensor cannot be set at the exact location where
measurement is desired, the resulting measured
temperature may deviate from the temperature in thedesired location. In this case, the desired temperature can be
set for the desired location by setting a temperature calibration
value. However, it is only effective within the input rated

TDS Conversion

TDS stands for Total Dissolved Solids. Conductivity of asolution results from the amount of salt, minerals or
dissolved gas. Conductivity is an index indicating total
amount of substance in a solution, and TDS indicates only
the amount of all dissolved solid substances.
TDS can be used correctly to compare the two solutions inwhich one ingredient, such as NaCl, is included. However,for comparison between a solution in which one ingredientsuch as NaCl is included and the other solution in whichmore than one ingredient is included, TDS error will occur.
TDS and conductivity are expressed with the following formula.
For Conductivity of SI unit (mS/m):
TDS (mg/L) = L (mS/m)

For Conductivity of older unit ( S/cm):
TDS (mg/L) = L ( S/cm)

This corrects the input value from the conductivity sensor.
When conductivity measured by the sensor may deviate fromthe conductivity in the measured location, the desired conductivity can be obtained by adding a sensor correction value.
However, it is only effective within the measurement range

If temperature rises by 1 , the conductivity rises by 2% at 25 basis in general.
Temperature coefficient differs depending on the solution type and its concentration,
which ranges from 0.50 to 2.50.
By inputting the temperature coefficient, temperature compensation can be calculated
to find the conductivity at 25 .
Temperature coefficient 2.00 %/ can be used for most of solutions.
If temperature coefficient of solution is already-known, enter the value. (Table 12.2-1)
If the conductivity at an arbitrary temperature T is already-known, and if reference
temperature is ST , conductivity C(ST) at the reference temperature can be obtained
according to the following formula.

12.3 Temperature Compensation Based on the Temperature Characteristics ofDeionized Water
Conductivity of deionized water is calculated by adding conductivity of deionized water
to conductivity caused by ionic impurities.
C(T) = F(T) + G(T)
C(T): Conductivity of solution at T
F(T): Conductivity of deionized water at T
G(T): Conductivity caused by ionic impurities at T
Conductivity of Deionized Water
Conductivity of deionized water is caused by dissociation of water molecules.
The dissociation of water molecules is greatly affected by the change oftemperature.
Conductivity of deionized water is measured based on the characteristics in (Table
12.3-1) (ASTM D 1125-91, JISK0130-1995).
