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.

4.5.1 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.

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.

4.6 Connection to mains power supply

4.6.1 Power supply connection (low voltage instruments)

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

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.

4.8 Sensor installation

4.8.1 Sensor positioning

The sensor must be installed in a socket or flow chamber that allows contact with the sample fluid to

be analyzed. The sensor and measuring instrument are connected by a cable. The standard sensor

cable lengths are 3, 5, 10, 15 and 20 meters. Ensure that the sensor will be mounted:

• perpendicular to the pipe

• on a horizontal pipe section (or on flow-ascending vertical pipe)

• minimum of 15 meters away from the pump's discharge side

• in a place where the sample flow is stable and rapid, and as far as possible from:

• valves

• pipe bends

• the suction side of any pumps

• a CO

2

injection system or similar

Note: There may be situations where not all the above conditions can be met. If this is the case, or you have any

concerns, please consult your Hach representative to appraise the situation and define the best applicable solution.

4.8.2 Recommended sample flow rate

For optimal response time, the recommended sample flow rate for both the K1100 and

M1100 sensors is 150 mL/min. Control the flow with the outlet valve on the flow meter (No. 3 in

Figure 8) to avoid foam developing inside the flow chamber which could lead to erroneous oxygen

measurement values.

T cut off value Set to 5°C above the sample temperature.

8.2.1 Measurement advanced configuration

Note: The offset feature described below should be used for minor measurement adjustments only, and not as an

alternative to a sensor calibration. Make sure your sensor has been correctly calibrated before applying this feature.

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

Option Description

Offset enabled Check this box to enable the user measurement offset option. If checked enter an

offset value or a target value:

Offset value Enter an offset value to manually adjust the measurement value. If the gas unit type

or gas unit (defined in the Measurement configuration screen) are changed the

offset value is automatically reset to zero.

Measurement This field cannot be updated. It shows the current measurement value with the offset

applied.

Target value Enter a target measurement value. The offset value is automatically computed so the

displayed measurement value will be equal to the target value.

Compute offset Select this button to recompute the offset value at any time during the measurement

process. The offset value will be computed based on the current and target

measurement values.

Out of range

protection

Check this box to enable the out of range protection (recommended). When enabled

and the measured value exceeds the instrument specification, the measurement

interval will be increased to 1 minute to protect the lifetime of the sensor spot. If

disabled, the lifetime of the spot can be negatively impacted if the sensor is exposed

to high oxygen concentrations for long periods of time.

Measurement

interval

Set the value to between 2 and 60 seconds to define the interval for refreshing the

measurement value on the display.

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.

8.2.2 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.

English 17

Option Description

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.

8.2.3 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:

0.9 1.1 4.0 4.3 4.4 5.6 7.0

8.2.4 Measurement interferences

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.

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

Option Description

Chlorinity/Salinity Select Chlorinity, Salt or All disabled.

Chlorinity/Salinity conc. For chlorinity or salt, it is required to enter the actual concentration in the sample.

8.2.5 Sample mode measurements

1. Press the start/stop function key (on the header bar) to initiate the sample measurement.

The text In progress and the measurement value are displayed sequentially. The measurement

process stops when the stop criteria selected are fulfilled.

2. The measurement process is stopped when:

• The stop criteria is fulfilled, typically when the gas concentration reaches the set threshold

• The start/stop function key has been pressed

• The Maximum time criteria is reached

18

English

• An error has occurred (e.g. sensor out)

3. When the sample measurement stops because the stop criteria are fulfilled, the gas

concentration and temperature are no longer refreshed. They indicate the measurement when the

stop criteria was reached. If the channel was configured for TPO or TPA calculation, enter the

parameters.

4. If the sample mode is stopped for another reason (user abort, max. time, or measurement error),

the aborted message is displayed.

8.2.5.1 TPO or TPA calculation

The TPO (Total Package Oxygen) and TPA (Total Package Air) features are available on the

instrument with a sensor measuring oxygen. To initiate these options, the instrument must be

configured in Sample mode and the TPO or TPA calculation must be enabled. The operator also

needs to ensure the package is shaken for about 5 minutes before measuring, and to know the total

volume of the package and the total volume of the contents of the package.

8.2.5.2 TPO and TPA parameters

1. Overflow volume: Total package size

2. Net content volume: Volume of liquid in the package

3. Press the Compute button to calculate the TPO or TPA. The parameters can be changed and the

value recalculated if necessary.

TPO values are displayed in ppm, TPA values in mL.

4. To store the measurement, press the OK button.

8.2.5.3 Stop criteria configuration

The stop criteria setting is available in theSample mode measurement option in the channel

configuration window.

Note: The parameters available for configuration depend on the type of stop criteria being defined.

1. Select Menu>Main>Configure the channel, then press the Sample Mode button and the Stop

criteria button.

Option Description

Above

threshold

The stop criteria is met when the gas concentration is greater than the parameter entered

in Threshold

Below

threshold

The stop criteria is met when the gas concentration is lower than the parameter entered in

Threshold

Stability The stop criteria is met when the variation of the gas concentration is smaller than the

parameter entered in Variation

Note: The number of samples taken into account to compute the Variation can be

adjusted using the parameter Depth.

Time The stop criteria is met when the elapsed time reaches the Max. time parameter.

Max. time The parameter Max. time is the maximum time allowed to reach the target. If Time is not

the type of stop criteria, then when this delay has elapsed, the measurement stops and the

message aborted is displayed.

Time filter The time filter allows you to filter the stop criteria. The sample mode is stopped when the

stop criteria is fulfilled for a time greater than the parameter Time Filter.

As an example, if criteria is set to Above threshold and Time Filter is set to 10 sec. the

measurement stops when the gas concentration is above the threshold for more than

10 seconds.

8.3 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.

Section 9 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.
