PRECAUTIONS
1. Installation Precautions

CautionThis instrument is intended to be used under the following environmental conditions (IEC61010-1):• Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of -20 to 50 (-4 to 122 ) that does notchange rapidly, and no icing• An ambient non-condensing humidity of 35 to 95 %RH• No large capacity electromagnetic switches or cables through which large current is flowing.
• No water, oil or chemicals or where the vapors of these substances can come into direct contact
with the unit
• The ambient temperature of the unit must be kept to under 50 . Otherwise the life of electronic parts(especially electrolytic capacitors) of the unit will be shortened.
Note: Do not install this instrument on or near flammable material even though the case of this
instrument is made of flame-resistant resin.

32. Wiring Precautions

Caution• Use a ring-type solderless terminal with an insulation sleeve in which the M3 screw fits when wiring
the FEB-102-ECH, ECM.
• Tighten the terminal screw using the specified torque. If excessive force is applied to the screw
when tightening, the terminal screw 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)
• 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 4-electrode/2-electrode conductivity sensor in accordance with the sensor input
specifications of the FEB-102- ECH, ECM.
• Keep the sensor cables and power cables separate, do not put them in the same cable clamp.
Note about the 4-electrode/2-electrode Conductivity Sensor Cable
The 4-electrode/2-electrode conductivity sensor cable is a highly-insulated (electrical) cable. Pleasehandle it with utmost care as follows.
• Do not allow terminals and socket of the 4-electrode/2-electrode conductivity sensor cable to come incontact 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 4-electrode/2-electrode conductivity sensor
cable should be wired with sufficient length.
• Keep the 4-electrode/2-electrode conductivity sensor cable and junction cable away from electricaldevices, such as motors or their power lines from which inductive interference emanates.

3. Operation and Maintenance Precautions

Caution• Do not touch live terminals. This may cause an electrical shock or problems in operation.
• Turn the power switch OFF when retightening the terminal or cleaning.
Working on or touching the terminal with the power switched ON may result in severe injury or death
due to electrical shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)• As the display section is vulnerable, do not strike or scratch it with a hard object or put pressure on it.

Setup should be done before using this instrument according to the user’s conditions:
Setting Conductivity input, Temperature input, EVT1 to EVT4 types, Communication, Transmission
output, Display setting, etc.
Setup is performed in the following groups.

If the user’s specification is the same as the factory default value of this instrument, or if user’s instrument
has already been installed in a system after setup was complete, initial setup is not necessary.
Proceed to Section ‘7. Calibration’ (p.50).
6.1 Turn the Power Switch ON.
For approx. 4 seconds after the power switch is turned ON, the input type is indicated in the

Conductivity Calibration Mode, Temperature Calibration Mode and Transmission Output Adjustment
Mode are described below.
7.1 Conductivity Calibration Mode
Deterioration of the 4-electrode/2-electrode conductivity sensor may cause the cell constant to change.
To correct the changed cell constant, calibration is performed.
Perform Conductivity Zero adjustment first, followed by Span adjustment.
However, if(Lock 1),
(Lock 2) or(Lock 3) is selected in [Set value lock(p.49)], the instrument cannot move to Conductivity Calibration Mode.
The following outlines the procedure for conductivity calibration.
1 When selecting(Last value HOLD) in [Transmission output 1 status when calibrating(p.46)] or in [Transmission output 2 status when calibrating (p.47)], select it while the 4-electrode/2-electrode conductivity sensor is being immersed in the solution currently calibrated.

Do not immerse the 4-electrode/2-electrode conductivity sensor in the standard solution.

If conductivity is 0 (zero), this adjustment is not necessary.
Setting range of the Conductivity Zero adjustment value differs depending on the measurement
range. (See Table 7.1-1.)
However, it is effective within the measurement range regardless of the Conductivity Zero adjustment
value.

7.2 Temperature Calibration Mode
Temperature calibration is performed by setting the temperature calibration value.
If(No temperature compensation) is selected in [Temperature compensation method (p.23)],
Temperature Calibration Mode is not available.
The unit cannot enter Temperature Calibration Mode in the following cases:• If(Lock 1),
(Lock 2) or(Lock 3) is selected in [Set value lock (p.49)].
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, thedesired temperature can be set for the desired location by setting a temperature calibration value.
However, it is 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
If temperature calibration value is set to -1.5 : 23.5 + (-1.5) = 22.0
Temperature calibration procedure is shown below.

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 span, the unit assumes that actuator trouble has occurred, and writes

In Serial communication, status can be read by reading Status flag 2 (EVT1, EVT2, EVT3, EVT4 output
flags).

• During Conductivity Calibration Mode or Temperature Calibration Mode
• When Conductivity input error alarm time is set to 0 seconds (minutes), or Conductivity input error
alarm span is set to 0.00.
8.8 Cycle Automatic Variable Function
If deviation between EVT value and measured value enters EVT cycle variable range,
the proportional cycle will be automatically extended in accordance with the deviation.

TDS Conversion

Perform Conductivity Zero adjustment first, followed by Span adjustment.
If(Lock 1),
(Lock 2) or(Lock 3) is selected in[Set value lock (p.49)], the unit cannot enter Conductivity Calibration Mode.
In Conductivity Zero adjustment, adjustment is performed so that
conductivity becomes 0, without immersing the 4-electrode/2-electrodeconductivity sensor in the standard solution.
In Conductivity Span adjustment, the 4-electrode/2-electrode conductivity
sensor is immersed and adjustment is performed while checking
conductivity.
However, it is effective within the measurement range regardless of theadjustment value.
When a sensor cannot be set at the exact location where measurement isdesired, the resulting measured temperature may deviate from thetemperature 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 effective within the input rated range regardless of thetemperature calibration value.
TDS stands for Total Dissolved Solids.
Conductivity of a solution 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 in which one
ingredient, such as NaCl, is included. However, for comparison between asolution in which one ingredient such as NaCl is included and the othersolution in which more than one ingredient is included, TDS error will occur.
TDS and conductivity are expressed with the following formula.
