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 0 to 50 (32 to 122 )that does not change rapidly, and no icing• An ambient non-condensing humidity of 35 to 85%RH• No large capacity electromagnetic switches or cables through which large current isflowing.
• No water, oil or chemicals or where the vapors of these substances can come into
direct contact with the unit.
• If the AER-101-TU is mounted through the face of a control panel, the ambient
temperature of the unit – not the ambient temperature of the control panel – must be
kept 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 caseof this instrument is made of flame-resistant resin.

2. Wiring Precautions

Caution• Do not leave wire remnants in the instrument, as they could cause a fire or a malfunction.
• Use a solderless terminal with an insulation sleeve in which the M3 screw fits whenwiring the AER-101-TU.
• 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 case may be damaged.
• This instrument does not have a built-in power switch, circuit breaker or fuse.
It is necessary to install a power switch, circuit breaker or 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 Turbidity/SS sensor which isconnected to the input terminal nor allow the power source to come into contact withthe sensor.
• Use the Turbidity/SS sensor made by OPTEX Co., Ltd.
• Keep the input wires and power lines separate.
43. Operation and Maintenance Precautions

Caution• Do not touch live terminals. This may cause an electrical shock or problems inoperation.
• Turn the power supply to the instrument OFF when retightening the terminal orcleaning.
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, be careful not to put pressure on, scratch or strike
it with a hard object.

7. Setup
Setup should be done before using this instrument according to the user’s conditions
Setting Turbidity/SS input, EVT type, Transmission output, Communication (C5 option),and Indication settings (Backlight selection, Turbidity/SS color, etc.)]
Setup can be conducted in the Turbidity/SS Input Group, EVT Action Group,
Transmission Output Group, Communication Group (C5 option) and Basic Function
Group.
If the user’s specification is the same as the factory default of the AER-101-TU, or if setup
has already been complete, it is not necessary to set up the instrument. Proceed to
Section “8. Calibration (p.35)”.
7.1 Turn the Power Supply to the AER-101-TU ON.
For approx. 4 seconds after the power is switched ON, the following characters areindicated on the Turbidity/SS Display. (Table 7.1-1)(Table 7.1-1)

Description
Take several examples of Formazin turbidity input value and Kaolin value in order toexamine the correlation between them. This must be done in the desired
measurement location.
Confirm that both Formazin turbidity input value and Kaolin value are linearly
related, and calculate span setting value using the value from each measurement
unit closest to the span setting value.
The following shows the calculating formula.
Span setting value = Current span value x Kaolin value / Formazin Turbidity input
value(e.g.) Current span value (Formazin): 100.0
Turbidity input value (Formazin): 80.0
Kaolin value: 60.0 mg/L
Span setting value = 100.0 x 60.0 / 80.0 = 75.0
[Kaolin (mg/L)] in [Measurement unit].
For the Span setting, set the value calculated at step 2 (e.g. 75.0).
