Cautions on Installation of Solenoid Valve for Jet / Brush Cleaning

1. Do not allow a sample solution to flow backward into the solenoid valve or to be replaced with the driving fluid.

For this take relevant measures; e.g. install a check valve to prevent inverse pressure between the inlet and outlet of the solenoid valve, or install the solenoid valve higher than the holder, especially when using the air jet/brush cleaning system.

2. Make sure to avoid the risk of corrosion of the solenoid body (bronze) and seal (nitrile rubber) by vapor or

gaseous components generated from a sample solution, especially when using the air jet/brush cleaning system.

2.1 Installing the Holder

2.1.1 ShippingandCheckingtheSpecications

When shipping the PH8HS (or PH8HSF) Submersion Holders, they should be suitably packed to avoid possible damage in transit. When you receive them, unpack them and check for visible signs of damage.

2.1.2 Selecting the Holder Installation Site

Install the submersion type holder so the sensor is mounted in the correct position.

Install the holder in a site where: a typical measurement value is obtained and the holder can be easily maintained.

Avoid an area where the measurement value varies signicantly as this can cause indicator hunting. When selecting the holder installation site, rst check that the solution temperature and ow velocity meet the sensor and holder specications, and also consider ease of maintenance.

CAUTION

Installation Location of Holders The holder should be used in a place that is as vibration free as possible. Using the holder in a place where it is a󰀨ected by vibration, may result in damage to the holder.

2-1

2.1.3 Installation Procedure

Pipe Mounting Submersion Type Holder

The submersion type holder can be installed on a rigid vertical 2-inch pipe (*1) vertically and mount a 40 mm arm pipe perpendicularly on as shown in Figure 2.1. Mount the holder assembly on the arm pipe so the sensor can be submerged in the measurement solution correctly.

For the holder with cleaner (*2), install the cleaner holder on the arm pipe using a clamp. The holder assembly should be mounted on the arm pipe.

Notes:

*1 If there is a rigid vertical 2-inch pipe near the submersion type holder installation site, mount a 40

mm arm pipe perpendicular to it.

*2 Do not submerge the holder assembly in the solution without sensor. If the holder assembly is

likely to become submerged in the solution, remove it from the stanchion. The cleaner holder may be left on the pipe.

Flange Mounting Holder

The ange mounting submersion type holder is normally used with a xed ange. A ange to mate with the holder ange should be provided by the user. When the mounting a submersion type holder, no gasket is required between the ange. All bolts are not required, so determine the number of bolts according to the condition of holder installation.

Observe Note (*2) above when installing the submersion type holder.

2.3 Cleaner Piping

This section applies only to the submersion type holder with cleaner.

2.3.1 Piping Precautions

(1) Provide a slight slack in a exible tubing between the cleaner and a mating device to allow ease

of maintenance.

(2) Determine the cleaner pipe size to allow su󰀩cient ow and pressure. Use 15 mm pipe for air

cleaning piping. If the water/jet cleaner pipe or water/brush cleaner pipe is subject to freezing temperature during winter, cover it with a suitable insulation material.

(3) Use a normally-open (opens when relay is energized) 15 mm diameter solenoid valve for the

2.4 Wiring

This section describes the wiring between the ultrasonic oscillator and cleaner, and between the solenoid valve, pump, and PH201G distributor. For the sensor wiring, refer to the chapter describing the sensor.

For the non-explosionproof ultrasonic oscillator, connect the cable from the cleaner directly to the terminals inside the PUS400G Ultrasonic Oscillator.

For details of PUS400G, refer to the separate IM 19C1B3-01E.

For the explosionproof ultrasonic oscillator, connect the cable from the cleaner directly to the terminals inside the PH8USF Ultrasonic Oscillator and PH8AL Alarm Box.

For detailsof PH8USF, PH8AL, refer to the separate IM 12B5U2-E.

2.4.1 Solenoid Valve Circuit Wiring

This is the wiring for the water jet or brush cleaning.

The wash timer in the Intelligent pH transmitter outputs a contact signal via the PH201G Distributor. You should wire this contact to operate the solenoid valve. If you are using the PH8PU1 Washer Pump and Tank, then the wiring is described in Sec. 2.5.3.

< 3. Maintenance/Inspection >

3. Maintenance/Inspection

3.1 Checking the O-ring that Seals Wetted Parts

The O-ring used in the wetted parts of the submersion type holder is made of a chemical-resistant uorocarbon rubber which is not e󰀨ected by corrosive liquids. Thus, it normally does not require any special checks other than the preventive maintenance procedure described in Sec. 3.1.2. However, if the O-ring should be damaged, replace it immediately to prevent future problems.

3.1.1 pH Sensor O-ring

When removing the sensor to the holder after maintenance, check that the surface of O-ring is free from corrosion. If corrosion is present, remove it completely or the sealing e󰀨ect be lost and the measuring solution enters the holder. The solution can corrode the cable and KCl supply tube. If they become corroded, dismount the sensor from the holder and check if the O-ring is free from corrosion.

If the O-ring loses its sealing e󰀨ect, replace it with a new one. When installing a new O-ring, remove the cable from the terminal board and pass it through the O-ring before reinstalling the sensor. See Figure 3.1.

3.1.2 Cleaner Mounting O-ring

This procedure applies to the submersion type holder with ultrasonic cleaner.

If the measurement solution enters the holder where the cable is stored, the internal holder parts may be corroded and must be replaced. To prevent this, check them periodically. However, if the O-ring has not been damaged by the measurement solution, the internal holder parts need not to be checked. As preventive maintenance, it is recommended that the O-ring be replaced every two years. To replace the O-ring in the explosionproof ultrasonic cleaner, refer to Sec. 3.2.3.

3.2 Checking the Cleaning Element

This section applies to the ow-through type holder with cleaning element. Check the cleaning element to maintain the ow-through type holder in good operating condition.

3.2.1 Jet Cleaning Element

If the cleaner does not clean the sensor electrode, check if the sensor nozzles are clogged. Use a 0.8 mm diameter wire to remove any material clogging the sensor nozzles.

Figure 3.2 Cleaning the Nozzle Holes

3.2.2 Cleaning the Brush

If the electrode becomes dirty, the brush may be excessively worn. When the brush is worn out, replace it. Insert a screwdriver into the cleaner hole to prevent the rotor from turning, and then turn the brush assembly counterclockwise. The brush can be easily removed from the rotor. See Figure 3.3. When mounting a new brush, reverse the disassembly procedure.

3.2.3 Ultrasonic Cleaning Element

For several weeks after starting the operation, check the ultrasonic cleaning element for corrosion. If corroded, replace it with the type most suitable for the measurement solution, selecting from among the element materials: SUS316 stainless steel, titanium and Hastelloy C. If a corroded element is not replaced, the solution may enter the ultrasonic element and cause problems. If this occurs, replace the cleaning element immediately.

[Non-explosionproofultrasoniccleaningelement]

(1) To remove a defective ultrasonic cleaning element, unscrew the cleaning element mounting

screw, so the cleaning element holder can be removed from the screw connector. Move the cleaning element out until the connector appears, and disconnect the vibrator leadwire connector from the holder side connector. See Figure 3.4.

F3.4E.ai

Figure3.4 Non-ExplosionproofCleaningElement

(2) Check that there is no corrosion around the O-ring sealed surface. It is recommended that the

O-ring be replaced whenever the element cleaned.

(3) Mounting a new ultrasonic cleaning element. After attaching the connector, rotate the cleaning

element two to three turns and store the cable inside the holder. Secure the cleaning element mounting screw. Check the cleaning element material by the marking on the surface of the vibrator element; H for Hastelloy, T for titanium, none for SUS316 stainless steel.
