residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at their expense. The following techniques can be used to reduce
interference problems:
1. Disconnect the equipment from its power source to verify that it is or is not the source of the
interference.
2. If the equipment is connected to the same outlet as the device experiencing interference, connect
the equipment to a different outlet.
3. Move the equipment away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the interference.
5. Try combinations of the above.

Product overview
The analyzer measures conductivity and calculates the pH in low-conductivity applications. The
system can include the controller as shown in Figure 1 or the controller can be installed as an
external component.
The system can be configured to function in numerous applications in the following industry sectors:
• Measurement in pure and ultrapure water, power plants, semiconductor industry, pharmaceutical
• Drinking water
• Industrial processes (chemistry, paper mills, sugar refineries, etc.)

Principle of operation (pH calculation)
The Polymetron 9523 analyzer adheres to the recommendations contained in the guidelines for
feedwaters, boiler water and steam quality for power and industrial plants.
The pH calculations can only be applied under the following strict chemical conditions:
English

• The sample must only contain an alkaline agent (ammonia, sodium hydroxide or ethanolamine)
• Any impurity is principally NaCl (sodium chloride)
• The concentration of impurity must be negligible in comparison to the alkaline agent
Control of conductivity values
Control of the minimum and maximum conductivity values depends upon the volatile conditioner.
These values are illustrated in the following two tables.
Note: AVT (All Volatile Treatment) - Conditioning concept where only volatile alkalizing agents are used; mainly
ammonia.

document.
Analyzer mounting
Attach the analyzer to a stable, vertical surface. Refer to the guidelines that follow and Figure 2.
Note: If an external controller is used, refer to the controller documentation for mounting instructions.
• Put the instrument in a location that has access for operation, service and calibration.
• Make sure that there is good view of the display and controls.
• Keep the instrument away from a heat source.
• Keep the instrument away from vibrations.
• Keep the sample tubing as short as possible to minimize the response time.
• Make sure that there is no air in the sample supply line.

Resin cartridge installation
Refer to the steps that follow and Figure 3 to install the resin cartridge.
1. Insert the steel tube into the quick lock connector.
2. Push the steel tube as far as possible into the measuring cell.
3. Take the resin cartridge and turn it upside down 2 or 3 times until the resin comes away from the
sides of the cartridge and settles at the bottom, at the opposite end to the marker line.
4. Unscrew the cap off the top of the cartridge, by the marker line. Discard this cap and the flat black
sealing cap following the safety and disposal information for used cartridges.
5. Place the end of the steel tube into the center of the cartridge.
6. Slowly raise the cartridge to the measuring cell and screw into place to obtain an airtight and
watertight fitting.

High-voltage barrier
High-voltage wiring for the controller is located behind the high-voltage barrier in the controller
enclosure. The barrier must remain in place except when installing modules or when a qualified
installation technician is wiring for power, alarms, outputs or relays. Do not remove the barrier while
power is applied to the controller.
Wiring for power
W A R N I N G
Potential Electrocution Hazard. Always disconnect power to the instrument when making electrical
connections.
W A R N I N G
Potential Electrocution Hazard. If this equipment is used outdoors or in potentially wet locations, a
Ground Fault Interrupt device must be used for connecting the equipment to its mains power source.

English 11
D A N G E R
Electrocution Hazard. Do not connect AC power to a 24 VDC powered model.
W A R N I N G
Potential Electrocution Hazard. A protective earth (PE) ground connection is required for both
100-240 VAC and 24 VDC wiring applications. Failure to connect a good PE ground connection can
result in shock hazards and poor performance due to electromagnetic interferences. ALWAYS connect
a good PE ground to the controller terminal.
Install the device in a location and position that gives easy access to the disconnect device and its operation.
N O T I C E
The controller can be purchased as either a 100-240 VAC powered model or a 24 VDC powered
model. Follow the appropriate wiring instructions for the purchased model.
The controller can be wired for line power by hard-wiring in conduit or wiring to a power cord.
Regardless of the wire used, the connections are made at the same terminals. A local disconnect
designed to meet local electrical code is required and must be identified for all types of installation. In
hard-wired applications, the power and safety ground service drops for the instrument must be 18 to
12 AWG.
Notes:
• The voltage barrier must be removed before making any electrical connections. After making all
connections, replace the voltage barrier before closing the controller cover.
• A sealing type strain relief and a power cord less than 3 meters (10 feet) in length with three 18gauge conductors (including a safety ground wire) can be used to maintain the NEMA
4X/IP66 environmental rating.
• Controllers can be ordered with AC power cords pre-installed. Additional power cords may also be
ordered.
• The DC power source that supplies power to the 24 VDC powered controller must maintain
voltage regulation within the specified 24 VDC-15% +20% voltage limits. The DC power source
must also provide adequate protection against surges and line transients.
Wiring procedure
Refer to the illustrated steps that follow and Table 1 or Table 2 to wire the controller for power. Insert
each wire into the appropriate terminal until the insulation is seated against the connector with no
bare wire exposed. Tug gently after insertion to make sure that there is a secure connection. Seal
any unused openings in the controller box with conduit opening sealing plugs.
