Electrocution hazard. In order to maintain the NEMA/IP environmental ratings of the enclosure, use

only conduit fittings and cable glands rated for at least NEMA 4X/IP66 to route cables in to the

instrument.

Cable gland wiring instructions

A waterproof cable gland is provided each time a cable must be connected inside the instrument.

The nickel-plated brass cable glands are EMC-types, designed so that the cable shields attach

directly to the instrument housing as a ground. Typical cable wiring instructions are detailed below.

1. Unscrew the cable gland nut. Inside, the assembly is composed of a rubber gasket, and two

metal washers. Note that the ethernet gland on panel and wall mount instruments does not have

washers and the gasket is cut.

2. If wiring a sensor cable, the cable has already been prepared so simply remove the piece of

plastic protection from the exposed shielding. For other cables, strip off external insulation as

required, and 25 mm of shielding. Strip the wires about 8 mm from their ends.

3. Pass the cable through the nut, the rubber gasket, and the two washers.

4. Pinch the shield so that its entire circumference is pressed between the two washers and pass

the cable into the housing, blocking the cable gland.

3 Instrument 6 Washers

N O T I C E

It is vitally important to ensure the shielding is pinched and secured between the two washers to ensure the

shielding attaches directly to the instrument housing as a ground. Failure to do this could cause damage to

the instrument, and for sensor cables give incorrect readings.

5. Reattach and tighten the cable gland nut.

6. Attach the wires to the corresponding terminal block connections.

Connection to mains power supply

Power supply connection (low voltage instruments)

For low voltage instruments (10-30 VDC), connection to the mains power supply is with a 8-pin

D A N G E R

Electrocution hazard. Always remove power to the instrument before making electrical connections.

High voltage instruments (100-240 VAC) have a 4-pin male connector pre-wired internally with a

male BINDER connector ready for mains connection. A compatible female connector is supplied with

the instrument.

If this female connector was supplied with a mains power plug already pre-attached (cable part

numbers 33031, 33032, 33033 and 33034) then the female connector can be plugged directly into

the instrument power connector. The two connectors are grooved to avoid an incorrect fitting. Tighten

the female connector to the instrument power connector finger-tight.

If no power cable was ordered with the equipment, a mains power plug must be connected to the

supplied female connector as described in the following procedure.

User-supplied power cable specifications:

• 3-wire (live, neutral and earth)

• cable Ø ≥ 7mm; ≤ 9.5mm

• wire selection ≥ 1mm

Prepare the user-supplied power cable as follows:

1. Strip off 23 mm (0.9 ins.) of shielding from the power cable.

2. Cut back the live and neutral wires to 15 mm (0.6 ins.) in length but leave the earth wire as is.

3. Then strip off a small amount of external insulation from the three wires as required.

Wire the female connector as follows:

1. Take the narrow end of the connector (4) in one hand and the main body (2) in the other and

unscrew the two. Pull away the cable clamp (3) and unscrew the end plug (1) to reveal the four

parts that make up the connector.

2. Loosen the screws on the cable clamp (3) to allow enough room to pass the power cable through.

3. Pass the power cable through the end plug (1), the main body (2), and the cable clamp (3), and

then connect the three wires (live, neutral and earth) to the connector (4) as follows:

1. Live (brown)

2. Neutral (blue)

3. Not used

Earth - Earth (green and yellow)

Note: The numbers and earth symbol are stamped on the end of the connector. Ensure it is connected

correctly.

4. Slide the cable clamp (3) back onto the connector (4) and tighten the screws on the clamp to

secure the cable.

5. Screw the two parts (4) and (2) back together.

6. Secure the power cable by screwing the end plug (1) back in place.

7. The female connector can now be plugged directly into the instrument power connector. The two

connectors are grooved to avoid an incorrect fitting. Tighten the female connector to the

instrument power connector finger-tight.

Connections to electronic boards

N O T I C E

Potential Instrument Damage. Delicate internal electronic components can be damaged by static electricity,

resulting in degraded performance or eventual failure.

Note: Any loose connection wires should be bundled tightly together with the use of nylon cable ties.

Sensor cable

An ORBISPHERE cable is needed to connect the sensor to the instrument. There is a cable gland for

cable passage, and the cable must be permanently connected to the measuring board connector. A

sensor cable is required with free wires on the instrument end. The free wires are connected to the

connector J8 on the measuring board, as detailed later in this chapter.

Electronic boards connectors

Connectors P8 on the main board (Figure 4 on page 10) and J7 and J8 on the measurement board

(Figure 6 on page 11 and Figure 7 on page 11) are made of two parts. Push down carefully the

black levers on either side of the connector and pull it out securely. Perform all connections with

these connectors unplugged. Once finished, attach the connectors to the boards by pushing them

firmly in place (levers up).

Measurement alarm relays

The three output relays are located on the measurement board.

They can be individually configured to Normally Open (NO) or to Normally Closed (NC) by

physically moving the jumper on each relay. The illustration is for the EC measurement

board (the positions are different for the TC measurement board):

• Upper relay is set to NC

• Middle relay is set to NO

• Lower relay is shown with no jumper

Note: For all measurement boards, J4 is relay 1, J5 is relay 2 and J6 is relay 3

Sensor installation

EC sensors

For EC sensor installation, servicing, and maintenance ensure you follow the instructions in the

Sensor Installation and Maintenance manual that was supplied with the instrument.

12

English

TC sensors

For TC sensor installation, servicing and maintenance ensure you follow the instructions in the TC

Sensor Installation and Maintenance manual that was supplied with the instrument. Pay particular

attention to the installation and connection of the purge gas supply.

N O T I C E

Do not place the TC sensor into a liquid sample until a constant supply of dry purge gas has been connected, as

liquid could condense inside the measuring chamber and cause damage to the thermal conductor chip.

To ensure the continuation of purge gas while the sensor is in contact with the sample, it is highly

recommended to use a backup purge gas cylinder with an automatic changeover valve that activates

when the first cylinder is empty.

The use of an ORBISPHERE Model 29089 gas regulator (or similar) is also recommended to deliver

a constant, pressure regulated supply of dry purge gas to the sensor, filtered to 40 μm.

In addition, and to prevent any damage to the sensor electronics, the use of a purge safety backup

unit (ORBISPHERE Model 32605) is highly recommended to ensure the supply of purge gas remains

uninterrupted to the sensor in the event of a mains power outage.

The above ORBISPHERE accessories are explained in more detail in the TC Sensor Installation

and Maintenance manual.

Option Description

Membrane Sensor’s membrane number selection.

Medium Liquid or gas phase.

Gas unit type Partial, Fraction, Dissolved.

Gas unit The list of available units depends on unit type selected above.

Note: This is the gas concentration measured by the EC sensor. When a composite unit

is selected (e.g. ppm » ppb) the unit will change depending on the range of the value to

display.

Liquid When medium is liquid, select water or a liquid with a different solubility (if available).

Display

resolution:

Maximum resolution depends on gas, membrane and unit. A maximum of 5 digits can be

displayed. Decimals can be limited to 0, 1, 2 or 3 decimals for easier reading. That does

not affect the actual resolution of data measured and stored, but only the data displayed.

Thermal cutoff: To protect the sensor, the thermal cutoff function allows for setting a sample high

temperature limit. If exceeded (during a Cleaning In Place cycle for example) the

electrical signal to the sensor is cut off, the measurement session is suspended and the

system displays a HOT alarm message. The system resumes when temperature drops

to 90% of the specified cutoff temperature.

• Thermal cut off options: Disabled / enabled.

• Thermal cut off temperature: To be set according to conditions.

2. TC sensor

The measurement configuration for a TC sensor is the same as for an EC sensor with the

addition of one extra selection criteria:

• Purge gas: From the drop-down list, select the purge gas being used for the TC sensor.

16

English

Measurement alarms configuration

Set the thresholds for the low/high concentration levels according to the application.

1. Select the Alarms button on the Measurement configuration screen:

Option Description

Low Low 2nd stage for too low concentration alarm.

Low 1st stage for too low concentration alarm.

High 1st stage for too high concentration alarm.

High High 2nd stage for too high concentration alarm.

Hysteresis The hysteresis is used to prevent relay flickering when the measurement is just at the alarm

levels. Set this to a minimum but enough to eliminate flickering. For example, if the High Alarm

is set to 40 ppb and the Hysteresis is set to 10% then the High Alarm is activated once the

measurement reaches 40 ppb but only deactivated once it drops below 36 ppb. With the Low

Alarm the opposite is true in that if the Low Alarm is set to 20 ppb and the Hysteresis set to 10%

then the Low Alarm is activated when the measurement drops below 20 ppb and deactivated

when it rises above 22 ppb.

Delay The delay in seconds, before alarms go on whenever concentration values go above ”High

alarms” or below “Low alarms”. Set this to a minimum value, but enough to avoid alarms for

non-representative peaks beyond the set level.

Measurement filter configuration

The filters are aimed at “flattening” the measurement curve in situations where the process shows

atypical peak values that could otherwise hamper the interpretation of measurement readings. The

filter is applied on the last set of measurements each time a measurement is taken.

1. Select the Filter button on the Measurement configuration screen:

Option Description

State Set the filters to Enabled or Disabled.

Type If enabled set the filter to Mean or Median.

Mean is the mathematical average of the last set (depth) of measurement values.

Median allows for eliminating atypical peak measurement values and averaging the

remaining ones. The calculation sorts the last measurement set (depth) by values, then

ignores the highest and lowest values and averages the remaining values (central depth).

Depth Number of measurements that make up a set.

Central depth Number of measurements to be used to determine the average.

Example: With a depth of 7 and central depth of 5, the 7 values are sorted and the highest (7.0)

and lowest (0.9) eliminated. The average of the center 5 is calculated as 3.88:

Check as appropriate.

Hold recovery time This parameter defines the interval during which the outputs remain frozen after

the measurement is no longer on HOLD. Set the value to between OFF and

10 minutes, according to the timing of your setup.

Continuous purge

during thermal cut off

If thermal cutoff has been enabled (see Measurement configuration on page 16),

then check this box to ensure that a continuous purge of the TC sensor takes

place while the measurement session is suspended due to the thermal cutoff

temperature value being exceeded.

Note: To manually set the TC sensor into a continuous purge mode, press the

Continuous Purge button that is available from the Services - Diagnostic -

Channel x - Amplifiers menu.

Offset and slope

corrections

Enable correction as appropriate. If enabled, the correction values for offset and

slope must be entered. These values cannot be negative.

Liquid to gas factor Enable correction as appropriate. If checked, the percentage correction factor must

be entered. This value cannot be negative.

Note: If you believe you need to enable these corrections, it is advisable to contact

a Hach Lange Service Representative first.

Interferences configuration

These options are available to take into account the influence of some components or gases in the

sample during measurement. All available interference corrections are disabled by default.

The following interference corrections are available:

• For oxygen measurements - CO

2

, H

2

S, Chlorine, Salt

Note: If you believe you need to enable any of the above, it is advisable to contact a Hach Lange Service

Representative first.

Interferences in oxygen measurement

In some applications, like in the beverage industry, there can be high concentrations of carbon

dioxide in the sample. Hach Lange recommends using the CO

2

interference option if a carbon

dioxide concentration of over 1% in gas phase, or 15 ppm in dissolved phase is present.

English

In the petroleum industry, the detection of oxygen is sometimes hampered by significant

concentrations of hydrogen sulfide in the sample. Hach Lange recommends using the H

2

S

interference option if the hydrogen sulfide concentration exceeds 0.15% in gas phase, or 5 ppm in

dissolved phase. To operate the oxygen sensor in these conditions requires using a different

sensor and electrolyte. When using this mode your system will experience sensitivity loss of about

50 times higher than the minimum sensitivity for the membrane.

1. Proceed as follows:

Chlorinity/Salinity Select Chlorinity, Salt or All disabled. For chlorinity or salt, it is required to enter the

actual concentration in the sample.

Measured data storage

There is one measurement file which contains the data generated by the measurement cycle. The

measurement file is updated in volatile memory and regularly copied in non-volatile memory (file

back-up). At start up the measurement file in volatile memory is updated with the file from the non-

volatile memory.

Note: Data stored in volatile memory is lost when instrument is powered off; non-volatile memory is permanent. In

case of an accidental power off event the instrument resumes measurement storage after the last measurement

stored in flash.

1. Select Measurement file from the Measurement menu:

Option Description

Storage mode Select No storage if data storage is not required. Select Store once to start

recording measurements. When the volatile memory is full the recording of

measurement stops. Select Rolling buffer for continuous recording of

measurements. When the volatile memory is full the latest measurement set

replaces the oldest one (first-in, first-out)

RAM time The delay between two recordings of measurement data.

FLASH time The delay between two data file transfers from volatile memory into non-volatile

memory. The last data file erases the previous one. This option is only available if

the Auto save in flash box is checked.

Save in flash now Press this button to store measurement data in flash immediately. After pressing

this button, press OK to initiate the process. A warning screen appears informing

you that the operation can take up to 30 seconds. Press Yes to continue or No to

abort.

Auto save in flash Check this box to save measurements in flash automatically. Measurements are

saved at regular time intervals as defined in the FLASH time box.

Purge data Clear all data in the volatile and non-volatile memories.

Start logging

measurements

Only available in Store once mode, this option starts or stops the measurement

recording session. Measurement recording ends automatically when the buffer is

full.

Open data Opens a table showing the measurments stored in the volatile memory (RAM).

Note: If TPO or TPA calculation is enabled, a ”TPO data” or a ”TPA data” button will

be available underneath the “Open data” button described above. Pressing this

button will display the TPO or TPA calculated data in a screen similar to that for

standard data.

Calibration

Calibrations can only be performed once the instrument has been installed and configured.

Note: The temperature sensor is factory calibrated and can only be changed by a Hach representative.

English

19

Definitions

To calibrate the gas to measure (main gas), the user usually puts the sensor in the main gas without

any interfering gas.

Calibrations can only be performed once the instrument has been installed, configured and the

channel has been set up. You must also ensure that you have the correct access rights to access the

calibration menu.

Select sensor calibration from the calibration menu.

There are two types of gas sensor calibration available, depending on the gas being measured and

the type of sensor being used:

1. In Air: For Oxygen and Ozone with an EC sensor. The sensor is exposed to air at atmospheric

pressure.

2. Direct value: Any gas with either an EC or TC sensor. This calibration exposes the sensor to a

gas with a known partial pressure, or a liquid sample with a known gas concentration.

EC gas sensor calibration

Calibration of the measured gas

1. Before initiating a calibration process, the calibration parameters must be set by pressing on the

Modify button. The last calibration parameters are memorized, so this step can be ignored if the

correct parameters are already set.

Option Description

Calibration mode 2 types available, depending on the gas being measured:

• Direct value: Any gas

• In Air (default): For O

2

or O

3

Medium Select liquid or gas (direct calibration only)

Concentration unit type Partial, fraction or dissolved (dissolved is for calibration in a liquid only)

Concentration unit The list of available units depends on unit type selected above.

Liquid Select as appropriate, available when liquid has been selected in medium

(above).

Value Enter the gas concentration according to the value in the calibration media, when

direct value is used.

Hold during calibration On by default, this stops any output from the instrument during the calibration

process to avoid sending invalid information to any connected device.

2. Press OK to start calibration

• A calibration screen will be displayed showing current measurement data which is continually

refreshed.

• The value “% ideal current” is a percentage of the current against the ideal current for the

membrane type selected. If this percentage is not within the accepted range, an error message

is displayed and the calibration process fails. A warning message can be displayed when this

value is close to the boundaries, but when calibration can be accepted.

• The message is first displayed in the result box. The dialog box with the error message or the

warning is displayed when the finish button is pressed.

• The value “% last calibration” shows the ratio between the current measurement and the

previous sensor calibration.

• The value “% variation” indicates the variation during the last 3 measurements, which is the

stability of the measurements. A variation as low as possible is needed for a precise

calibration.

• The display shows the actual calibration parameters, and the actual readings (temperature,

barometer, current).
