(condensates, cleaning cycles and

heat exchangers)

Installation

Mounting

W A R N I N G

Personal injury hazard. Removal of a sensor from a pressurized vessel can be

dangerous. Installation and removal of these sensors should be done by

individuals trained in proper high pressure and temperature installation. Always

use industry approved hardware and safety procedures when dealing with high

pressure and/or temperature fluid transport systems.

For examples of sensors in different applications, refer to Figure 2 or

Figure 3. The sensor must be calibrated before use. Refer to Calibrate

the sensor on page 11.

Connect the sensor to the module

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

Electrocution Hazard. High voltage wiring for the controller is conducted 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, relays or analog and network cards.

NOTICE

Potential Instrument Damage. Delicate internal electronic components

can be damaged by static electricity, resulting in degraded

performance or eventual failure.

To install the module and connect the sensor, refer to the illustrated

steps on the following pages and Table 3. Be sure to connect the white

wire with the red tip from the sensor to the controller chassis.

Note: If the sensor cable is not long enough to reach the controller, an interconnect

cable and junction box are required to extend the distance.

Operation

User navigation

Refer to the controller documentation for keypad description and

navigation information.

Configure the sensor

Use the Configure menu to enter identification information for the sensor

and to change options for data handling and storage.

1. Push the MENU key and select Sensor Setup, [Select Sensor],

Configure.

2. Use the arrow keys to select an option and push ENTER. To enter

numbers, characters or punctuation, push and hold the UP or DOWN

arrow keys. Push the RIGHT arrow key to advance to the next

space.

Option Description

EDIT NAME Changes the name that corresponds to the sensor on

the top of the measure screen. The name is limited to

10 characters in any combination of letters, numbers,

spaces or punctuation.

SENSOR S/N Allows the user to enter the serial number of the

sensor, limited to 16 characters in any combination of

letters, numbers, spaces or punctuation.

SELECT MEASURE Changes the measured parameter to conductivity

(default), TDS (total dissolved solids), salinity or

resistivity. When the parameter is changed, all other

configured settings are reset to the default values.

DISPLAY FORMAT Changes the number of decimal places that are

shown on the measure screen to auto (default),

X.XXX, XX.XX, XXX.X or XXXX. When set to auto, the

number of decimal places changes automatically with

changes in the measured value.

MEAS UNITS Changes the units for the selected measurement—

conductivity: µS/cm (default), mS/cm, µS/m, mS/m or

S/m.

Option Description

TEMP UNITS Sets the temperature units to °C (default) or °F.

T-COMPENSATION Adds a temperature-dependent correction to the

measured value—linear (default: 2.0%/°C, 25 °C),

ammonia, temp table (enter x,y points in ascending

order), none, natural water or pure water. For special

applications, a user-defined linear compensation can

be entered (0–4%/°C, 0–200 °C). Natural water

compensation is not available for TDS.

CELL CONSTANT Sets the cell constant range to 0.05, 0.5, 1.0 (default),

5.0, 10.0, 0.01 Polymetron, 0.1 Polymetron, or

1.0 Polymetron. After the range is selected, the user

can enter the certified K value from the label on the

sensor cable. When the certified K value is entered,

the calibration curve is defined.

CABLE LENGTH Sets the actual length of the sensor cable to improve

measurement accuracy (default: 20 ft (Polymetron

sensors default: 5 ft)).

TEMP ELEMENT Sets the temperature element for automatic

temperature compensation to PT100 or

PT1000 (default). After selection, the user should

enter the certified T-factor from the label on the sensor

cable for best accuracy. If no element is used, the

type can be set to manual and a value for temperature

compensation can be entered (manual default: 25 °C).

Note: If a sensor with a PT100 or PT1000 element is

set to manual and the sensor is replaced or the sensor

days are reset, the TEMP ELEMENT automatically

changes to the default setting.

FILTER Sets a time constant to increase signal stability. The

time constant calculates the average value during a

specified time—0 (no effect, default) to 60 seconds

(average of signal value for 60 seconds). The filter

increases the time for the sensor signal to respond to

actual changes in the process.
