F03-01 SUS304 ELECTRODE

**Electrodes and Accessories F03-** @ 

## **A Wide Variety of Electrodes for Long Lasting Reliability** 

- Standard Electrodes are made of stainless steel (SUS 304) and can be used in applications for purified water. 

- SUS316 Electrodes can be used in applications where resistance to corrosion is required. Titanium and Hastelloy Electrodes can be used in applications where resistance to acid is required. 

- For applications where long electrodes are required, a connection nut and two Lock Nuts can be used to extend the electrodes 1 m at a time. 

   - **Refer to** _**Safety Precautions for Electrodes and Electrode Holders.**_ 

## **Orderin Information g**

## **Insulated Electrodes** 

Electrodes are insulated with a plastic sheath to prevent them from touching each other and to isolate them from debris in the liquid. Before application, strip back about 10 cm of the sheath at the end to ensure sufficient conductivity.

## **Electrode Separators** 

When long electrodes are required, use Separators at each joint (every 1 m) to prevent the Electrodes from touching each other. Use a 1-pole Separator with BF Electrode Holders. The five-pole model can be used with PS-5S and PS-4S Electrode Holders. Separators cannot be used with PS-31 Electrode Holders.

## **Safet Precautions for Electrodes and Electrode Holders y** 

## ! **WARNING** 

**==> picture [35 x 66] intentionally omitted <==**

Do not touch the terminals while power is being supplied. Doing so may possibly result in electric shock. 

Do not attempt to disassemble, repair, or modify the Controller while power is being supplied. Doing so may occasionally result in electric shock. 

## **Precautions for Safe Use** 

Do not use the Controller in locations subject to explosive or combustible dust, combustible gas, flammable vapors, corrosive gas, excessive dust, salt-water spray, or water drops. 

## ■ **Electrode Precautions** 

## **Precautions for Correct Use** 

- Always disconnect the 61F when a tester to perform insulation resistance tests on the Electrode circuit. 

- If the Electrodes are to be cut, bevel the cut surface. 

**==> picture [243 x 162] intentionally omitted <==**

**----- Start of picture text -----**<br>
● Be careful of the distances between<br>Electrodes.<br>Allow a sufficient distance (normally 1 m)<br>between Electrodes if they are used in<br>seawater or sewage.

- **Electrodes must be cleaned.** 

**==> picture [243 x 156] intentionally omitted <==**

**----- Start of picture text -----**<br>
 Electrodes must be cleaned.<br>• At about six months after installation,<br>remove the Electrodes and use fine  Air hole dia.:<br>sandpaper to remove film from the  Approx. 10<br>surface. After that, clean the<br>Pipe with<br>Electrodes once or twice a year. If the  diameter of<br>Electrodes are used in liquid with a  approx. 4” min.<br>lot of dirt or scum, insulating film may<br>form, particularly on the surfaces of  Amount of Waste<br>the Electrodes, and result in  Material<br>Accumulating<br>operating failures. Remove the  between Periodic<br>insulating film once every three  Cleanings<br>months or so. For sewage tanks,  Sewage tank<br>sewage, oil film, or other applications  and tank surface<br>with a lot of waste material, use a<br>pipe such as the one shown at the<br>right.<br>**----- End of picture text -----**<br>


   - Use a pipe with a diameter of at least four inches. 

   - Install the pipe with a diagonal cut at the end as shown in the figure at the right according to the estimated waste material accumulation. 

   - Provide an air ventilation hole with a diameter of approx. 10 mm on the upper part of the pipe. 

- Breakwater Pipe Mounting Precautions 

**==> picture [237 x 143] intentionally omitted <==**

**----- Start of picture text -----**<br>
Install a breakwater pipe as shown in<br>the figure at the right for applications  Air hole dia.:<br>with large waves or fast flow, such as  Approx. 10<br>for water purification.<br>Make at least<br>• Use a pipe with a diameter of at  four opposing<br>least four inches. holes with a<br>diameter of 6 to<br>• To improve the circulation of  10 mm near the<br>liquid inside the pipe, make at  end of each<br>least four opposing holes with a  Electrode.<br>diameter of 6 to 10 mm near the  Pipe with a<br>end of each electrode. diameter of at<br>least four inches.<br>• Provide an air ventilation hole<br>with a diameter of approx. 10 mm<br>on the upper part of the pipe.<br>**----- End of picture text -----**<br>


- The procedures above also apply to using Electrode bands. 

## ● **Be careful of the operating level.** 

Changes in the type of liquid or the power Electrode supply voltage may cause the operating position Holder to fluctuate somewhat even when the tip of the Electrode reaches the level of the liquid. Separator 

## ● **Use separators.** 

When the required length of the Electrode is 1 m or more, use a Separator at each joint between two Electrodes to prevent the Electrodes from coming into contact each other in the water. 

## ● **Be careful of suspended matter causing Electrodes to come into contact with each other.** 

Use Tubing Electrodes if factors such as suspended matter cause Electrodes to come into contact with each other. To ensure conductivity, strip off at least 100 mm from the end of the Tubing and do not use Tubing on the common (earth) Electrode. 

## ● **Mount Electrodes vertically.** 

Water scum can easily accumulate on insulated parts and may cause insulation failure. Mount the Electrodes vertically.

## ■ **Electrode Holder Precautions** 

## **Precautions for Correct Use** 

- Never mount the Electrode Holder horizontally. Mounting the Electrode Holder horizontally may cause liquid to leak from the Electrode Holder and result in 61F reset failure. 

- The resin may become discolored after long-term use or storage. This is normal and does not present any problems in using the product. 

- When wiring the BF, use M6 crimp terminals. 

- Do not pull on the cable. 

- Disconnect the wiring with the Level Controller before inspecting Electrode Holders. 

- Use OMRON 61F Floatless Switches for control devices. 

- Consult with your OMRON representative before using the BF in any liquid other than water. 

## **Precautions for Tightening Torque and Work**

||Electrode Holder installation section (M18)<br>(See note 2.)|196.1 N·cm|



- **Note: 1.** A gasket is supplied with the BS-1. A gasket is not required to mount the BS-1T. (One is not supplied.) 

   **2.** Wind commercially available sealing tape two or three times around the M18 screw section before tightening the screws. 

   **3.** When installing the wiring, secure nut 2 with a wrench so that no force is applied to the terminal bolt, and complete the tightening with nut 1 (as in the following figure). If nut 2 is not secured, the load on the terminal bolt may cause leakage of steam and pressure.

- Always use an F03-11 Protective Cover if the BF-3 (-5) is used outdoors or in locations subject to water, dust, dirt, or other foreign matter. Foreign matter adhering to the electrode insulators may cause incorrect operation due to leaking.
