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.
