PRECAUTIONS
1. Installation Precautions
Caution
This 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 is flowing.
• No water, oil or chemicals or where the vapors of these substances can come into direct contact
with the unit
• If the WIL-101-ORP is installed within a control panel, the ambient temperature of the unit – not the
ambient temperature of the control panel – 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.

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 when wiring the
WIL-101-ORP.
• 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)
• For a 24 V AC/DC power source, do not confuse polarity when using direct current (DC).
• 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 ORP Combined Electrode Sensor in accordance with the sensor input specifications of the
WIL-101-ORP.
• Keep the input wires and power line separate.
Note about the ORP Combined Electrode Sensor Cable
The ORP Combined Electrode Sensor cable is a highly-insulated (electrical) cable. Please handle it
with utmost care as follows.
• Do not allow terminals and socket of the ORP Combined Electrode Sensor cable to come 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 ORP Combined Electrode Sensor cable
should be wired with sufficient length.
• Keep the ORP Combined Electrode Sensor cable and junction cable away from electrical devices,
such as motors or their power lines from which inductive interference emanates.
Connection
The ORP Combined Electrode Sensor cable has the following terminals.
Symbol Terminal
M Metal electrode terminal
R Reference electrode terminal
3. Operation and Maintenance Precautions
Caution
• Do not touch live terminals. This may cause an electrical shock or problems in operation.
• Turn the power supply to the instrument 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.

Shield Wire
Be sure to ground only one end of the shield wire so that current cannot flow to the shield wire.
If both ends of the shield wire are grounded, the circuit will be closed, resulting in a ground loop.
This may cause noise. Be sure to ground the FG terminal.
Recommended cable: OTSC-VB 2PX0.5SQ (made by Onamba Co., Ltd.) or equivalent
(Use a twisted pair cable.)
Terminator (Terminal Resistor)
The terminator is mounted at the end of the wire when connecting a personal computer with
multiple peripheral devices. The terminator prevents signal reflection and disturbance.
Do not connect a terminator with the communication line because each WIL-101-ORP has
built-in pull-up and pull-down resistors instead of a terminator.
Communication converter IF-400 (sold separately) has a built-in terminal resistor.

8. Setup
Setup should be done before using this instrument, according to the user’s conditions:
Setting the ORP input function (input high limit, input low limit), Output function (A11, A12, A21, A22
types), Special function (Communication, Cleansing action, etc.).
Setup can be conducted in the ORP Input Function Group, Output Function Group and Special Function
Group.
If the user’s specification is the same as the factory default of the WIL-101-ORP, or if setup has already
been completed, it is not necessary to set up the instrument. Proceed to Section “9. Calibration (p.33)”.
8.1 Turn the Power Supply to the WIL-101-ORP ON.
For approx. 4 seconds after the power is switched ON, is indicated in the ORP Display.
During this time, all outputs are in OFF status, and LED indicators except the Power Indicator go off.
After that, measurement starts, indicating ORP in the ORP Display and an item selected in [Setting
Display indication (p.27)] in the Setting Display.
This status is called ORP Display Mode or Cleansing Output Mode.
8.2 ORP Input Function Group
To enter the ORP Input Function Group, follow the procedure below.
1Press the Key once in ORP Display Mode or Cleansing Output Mode.
2Press the Key once.
The unit proceeds to the ORP Input Function Group, and ’Moving average data amount’ appears.

• Setting range: 1 to 20
Input high limit 1999 mV
• Sets the high limit value for ORP input indication.
• Setting range: Input low limit value to 1999 mV
Input low limit -1999 mV
• Sets the low limit value for ORP input indication.
• Setting range: -1999 mV to Input high limit value
ORP input filter time constant 0.0 sec.
• Sets ORP input filter time constant.
If the value is set too large, it affects A output due to the delay of response.
• Setting range: 0.0 to 60.0 seconds
A output when input errors occur Disabled
• If input errors, such as ORP Combined Electrode Sensor burnout or short-circuited
occur, A output Enabled/Disabled can be selected.
If “Enabled” is selected, A output and A output status will be maintained
when input errors occur.
If “Disabled” is selected, A output and A output status will be turned OFF
when input errors occur.
• If (Cleansing output) is selected in [A type], cleansing action takes
priority regardless of this selection.
• : Enabled
: Disabled
