D A N G E R
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.

2 Shield 5 O-ring 8 Gland nut
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
BINDER connector (supplied).
Note: The connectors are grooved to avoid an incorrect fitting to the instrument.
Connect the power cable to the connector as follows:

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 ≥ 1mm2, AWG18; ≤ 2.5mm2, AWG14
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.
English 9

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.

Measurement configuration
1. EC sensor
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:

Advanced configuration
1. EC sensor
Option Description
Enable negative concentration Check as appropriate.
2. TC sensor
Option Description
Enable negative
concentration
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 - CO2, H2S, 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 CO2 interference option if a carbon
dioxide concentration of over 1% in gas phase, or 15 ppm in dissolved phase is present.
18 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 H2S
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:
Option Description
CO2 or H2S Select CO2, H2S or All disabled.
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 O2 or O3
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).
