Electrode Holder

PS-@S(R)/-31

Separate Electrode Holders for Water

Supply and Drainage Control in Buildings.

Small, Lightweight Electrode Holders for

Use as Built-in Components.

• The PS-@S(R) are separate Electrode Holders that allow the

Electrodes to be withdrawn easily for inspection.

• The PS-@S(R) come in 3, 4, or 5 pole models for supply and

drainage of tap water in buildings.

• PS-31 is a small and light-weight Electrode Holder that is

suitable for installation in limited space and built-in

components.

Refer to Safety Precautions for Electrodes and

Electrode Holders.

Ordering Information

■ Electrode Holders

■ Accessories (Order Separately)

Specifications

Note: 1. The Two-wire Electrode Holders (R models) have an inbuilt resistor of 6.8 kΩ. They should be used with the Two-wire 61F Controllers.

2. The PS-31 is already connected to the electrodes. The electrodes come in lengths of 300 mm and 1,000 mm. Specify the length when

ordering. The electrodes can be cut to the desired length.

3. PS-31 comes in a 3-pole model only.

Safety Precautions for Electrodes and Electrode Holders ● Electrodes must be cleaned. !WARNING 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.
PAGE 6
■ 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.

Safety Precautions for All Level Controllers Refer to the Safety Precautions section for each product for specific precautions applicable to that product. !WARNING 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 product while power is being supplied. Doing so may occasionally result in electric shock.
