Password-Protected Access

For security, you can enable a passcode feature to restrict access to configuration and calibration settings to authorized personnel only. See Section 7.5 for details.

Calibration Methods

Because each sensor has a unique zero point and span, always zero the sensor in air when calibrating it for the first time (Section 8.2). Depending on the configured measurement (conductivity, % concentration or TDS), different methods are available for calibrating sensor span (see Section 8.3, 8.4 or 8.5 respectively). The analog output loop can also be calibrated (Section 8.6).

Analog Output

The transmitter’s isolated 4-20 mA analog output can be assigned to represent one of these:

• Measured conductivity, % concentration or TDS

• Measured temperature.

Parameter values can be entered to define the endpoints at which the 4 mA and 20 mA analog output values are desired (range expand). For analog output setup details, see Section 7.4.

NOTE: During calibration, the analog output is automatically held at the last measured value

and, upon completion, returned to its active state.

Figure 4-1 shows the terminal block arrangement and terminal designations for the transmitter.

NOTE: All terminals are suitable for single wires up to 14 AWG (2.5 mm2).

Wiring Tip! To comply with European Community (CE) electromagnetic compatibility requirements, follow these general wiring guidelines:

1. Locate transmitter as far as possible from motors and other non-CE certified devices with excessive electromagnetic emissions.

2. Use specified ferrites and cables. Failure to do so may eliminate compliance. Locate all ferrites as close as possible to the transmitter.

• DC Power Supply Cable: Connect cable shield to earth ground at the supply end. Loop

cable 2-1/2 times through ferrite (Steward #28B0686-200, Fair-Rite Corp. #2643665702 or equivalent).

• Sensor Cable: Keep cable shields as short as possible. At the transmitter end, connect

the outer shield to earth ground, and the inner shield to the SHIELD terminal. Clamp ferrite (Steward #28A2025-OAO, Fair-Rite Corp. #0431164281, or equiv-alent) on sensor cable.

• Analog mA Output Cable (four-wire hookup only): Connect cable shield to earth ground

at the supply end. Loop cable 2-1/2 times through ferrite (Steward #28B0686-200, FairRite Corp. #2643665702, or equivalent).

4.1 HC1 Series Electrodeless Conductivity Sensor Wiring

Depending on how transmitter is mounted, route the sensor (or interconnect) cable into the transmitter as follows:

• Wall/Pipe-mounted Transmitter: Route cable through left side cable entry knockout hole

in the back cover.

• Panel-mounted Transmitter: Route cable behind panel to the exposed TB2 terminal

strip.

• Integral Sensor-mounted Transmitter: Route cable through a 1/2” NPT female close

coupler and then through the swivel ball knockout hole and center hole in back cover. (Do not open left side cable entry knockout hole in back cover.)

Wiring Tip! Route the sensor cable in 1/2-inch, grounded metal conduit to protect it from moisture, electrical noise, and mechanical damage.

For installations where the distance between sensor and transmitter exceeds the sensor cable length, indirectly connect the sensor to the transmitter using a junction box and interconnect cable.

NOTE: Do not route the sensor cable in any conduit containing AC or DC power wiring

(“electrical noise” may interfere with the sensor signal). Also, always re-calibrate the system when the cable length between sensor and transmitter changes.

Refer to Figure 4-2 and connect the sensor (or interconnect) cable wires as shown, matching colors as indicated. (Terminal 6 is unused.)

NOTE: For systems not requiring CE compliance and lacking an earth ground, connect the

outer shield to Terminal 3 on TB2.

SPECIAL CASE — ALTERED SENSOR CABLE LENGTH

Changing the standard 20 ft. (6 m) sensor cable length, by shortening it or adding an interconnect cable, affects temperature measuring accuracy. The factory-certified T factor is based on standard cable length. To compensate for altered cable length measuring error, change the certified T factor entry: Shortened Sensor Cable: To increase the transmitter temperature reading to match the known solution temperature, decrease the T factor by 3.85 ohms for each °C difference. Added Interconnect Cable: To decrease the transmitter temperature reading to match the known solution temperature, increase the T factor by 3.85 ohms for each °C difference.

Example: Suppose the known solution temperature is 50°C and the transmitter reads 53°C due

to interconnect cable resistance. Multiply the 3°C difference by 3.85 ohms to get 11.55. Then increase the sensor T FACTOR by adding 11.55 to it and entering that value. If, due to a shortened sensor cable, the transmitter was reading 3°C less than the known solution temperature you would decrease the sensor T FACTOR by subtracting 11.55 from it.

The higher the filter time, the longer the analog output signal response time will be to a change in the measured value.

8.1 Important Information8.1 Important Information

8.1 Important Information8.1 Important Information

Each electrodeless conductivity sensor has a unique zero point and span. Consequently,

always zero the sensor when calibrating it for the first time (Section 8.2). Zeroing provides

the best possible measuring accuracy. After zeroing, calibrate for sensor span using one of the available methods, and periodically thereafter to maintain best measurement accuracy. Over time, some processes such as heavy slurries may plug the sensor hole, causing minor measurement errors. The time between calibrations, and the rate of measurement drift can vary considerably with each application and its specific conditions.

Calibration Tip! Establish a maintenance program to keep the sensor relatively

clean and the measuring system calibrated. The weekly or monthly intervals between performing maintenance will be influenced by the characteristics of the process solution, and can only be determined by operating experience.

Since the inherent ohm value of each sensor’s Pt 1000 RTD temperature element varies slightly, each element is tested to provide a unique, factory-certified temperature T FACTOR shown etched on the sensor housing. If this factor was not previously entered during configuration in Section 7.2, subheading “SET T

FACTOR,” enter it now before zeroing or calibrating to provide the best

possible measuring accuracy.

NOTE: When the passcode feature is enabled (Section 7.5), you must successfully enter the

passcode before attempting to calibrate the transmitter.

immersing it into a conductivity reference solution, and entering a reference for temperature compensation, and the known linear % per °C slope and conductivity value of the reference solution.

• SAMPLE CAL Method: This method allows keeping the sensor installed in the

process, but requires you to obtain a process sample, determine its value by laboratory analysis or comparison reading, and enter that value.

• ELECTRONIC CAL Method: This method requires that the sensor be removed from

1. Prepare the conductivity reference solution using your normal method. Its value should be near the typical measured process value for best accuracy. When the value is relatively low (between 200 and 100,000 microSiemens/cm), the data in TABLE E on the next page can be used to prepare the reference solution. Add the listed grams of pure, dried NaCl to one liter of high purity, de-ionized, CO obtain the listed conductivity. Solution conductivity can be decreased by dilution with de-ionized water.

When the transmitter is set to measure % concentration but you want to calibrate using a conductivity reference solution, please refer to Section 8.3, subsection “COND CAL Method” and follow steps 1 through 13.

When the transmitter is set to measure TDS, only the “TDS CAL” method is available to calibrate sensor span.

Depending on application circumstances, periodically calibrate the transmitter to maintain measurement accuracy.

Maintenance Tip! Upon startup, frequently check the system until operating

experience can determine the optimum time between calibrations that provides acceptable measurement results.

Calibrate the transmitter using a method described in Section 8.3, 8.4 or 8.5. Calibrating with

old, contaminated or diluted reference solution may cause measure-ment errors. Do not reuse reference solutions. Note that the value of a reference solution changes as its temperature

changes. Therefore, always allow the temperatures of the sensor and reference solution to equalize while calibrating.

10.2 Avoiding Electrical Interference

10.2 Avoiding Electrical Interference10.2 Avoiding Electrical Interference

Recommendation: Do not run sensor cable (and interconnect cable, if used) in

same conduit with AC or DC power.

Maintenance Tip! Excess cable should not be coiled near motors or other

equipment that may generate electrical or magnetic fields. Cut cables to proper length during installation to avoid unnecessary inductive pickup (“electrical noise” may interfere with the sensor signal).
