GENERAL INFORMATION

Product Description

The MPA-48 Multi-Parameter Analyzer comes standard with 4 channels for the continuous

measurement of dissolved oxygen, suspended solids, pH and/or ORP in an aqueous solution. It can be

easily upgraded to handle up to 8 channels with the addition of daughter boards and sensors. The

microprocessor-based electronics of the MPA-48 analyzer provide a high degree of flexibility and ease of

use. The instrument is designed to operate with any combination of InsiteIG sensors in a variety of

applications. The DO sensor to be used with this analyzer is an optical type sensor that measures the

fluorescence and quenching reactions of a ruthenium complex that is immobilized in a sol-gel matrix.

The SS sensor operates on the principle of single gap light absorption as a means of detecting the

presence of suspended solids. The pH and ORP sensors are flat glass electrodes.

The Model 10 Dissolved Oxygen sensor is designed for the continuous monitoring of dissolved

oxygen in water and wastewater where parts per million accuracy is required. The unit will display

dissolved oxygen content in PPM, mg/l or %SAT. The resolution in PPM and mg/l mode is 0.01 over a

range of 0.00 to 3.99 and 0.1 over a range of 4.0 to 25.0. The resolution in %SAT mode is 0.1%SAT

over a range of 0.0 to 99.9%SAT and 1%SAT over a range of 100 to 400%SAT. Temperature is

displayed in 0.1 degree Celsius increments over a 0.0 to 50.0 degree Celsius range or 1 degree

Fahrenheit increments over a 32 to 122 degree Fahrenheit range. It incorporates self-cleaning optics via

air or water jet.

The Model 15 TSS sensor has been designed for medium ranges (0 to 30,000 mg/l) as commonly

found in aeration basins of wastewater treatment plants and comes in pipe insertion configurations. The

Model 15L sensor has been designed for low ranges (0 to 1500 mg/l) as commonly found in effluent

streams. Both sensors utilize an infrared emitter to minimize color effects and compensates for emitter

variations due to temperature by measuring source brightness. They incorporate self-cleaning optics via

air or water jet.

The Model M50 is a microprocessor based preamp interface for the M51 and M52, pH and ORP

electrodes (please specify pH or ORP when ordering the M50). The unit will display the pH value in 0.01

pH resolution over a range of zero to 14.00 pH. However, the pH electrode is only rated for a pH range

of 2 to 12. The unit will display the ORP value in 1 mV resolution over a range of -2000 to 2000 mV.

Water temperature may also be measured for automatic temperature compensation. The temperature

may be displayed in degrees Celsius or degrees Fahrenheit. Temperature is displayed in 0.1 degree

Celsius increments over a 0.0 to 50.0 degree Celsius range or 1 degree Fahrenheit increments over a 32

to 122 degree Fahrenheit range. They incorporate self-cleaning via air or water jet.

Packaging

The analyzer is housed in a NEMA 4X enclosure (see Drawing IIG07N111 for Outline and Mounting)

and is designed for outdoor mounting. For areas where the environmental temperature is expected to

drop below 14 degrees Fahrenheit (-10 degrees Celsius) for extended periods of time, the optional

automatic heater assembly is recommended.

INSTALLATION

1. The MPA-48 analyzer should be located to allow convenient access for an operator to read and

technician to install and maintain. A rear rail mounting kit is available for the standard enclosure

(see Drawing IIG07N110). This mounting kit is design for a standard 2” handrail but can be

adapted to square or angle handrails as well.

DO NOT! Locate the analyzer where it is likely to be

damaged during unrelated or other periodic maintenance such

as pressure washing catwalks.

2. Mount the sensor in the desired location. InsiteIG can supply a sensor handrail mounting kit that

easily mounts to most handrails and slide locks the sensor into place with out the use of tools.

(See drawings IIG02N004, IIG02N005, IIG03N004 and IIG03N005). Again, this sensor mounting

kit is design for a standard 2” handrail but can be adapted to square or angle handrails as well.

DO NOT install a pH/ORP holder (Model 50) without a pH

cartridge (Model 51) or an ORP cartridge (Model 52) installed

and properly seated in the pH/ORP holder. Installing a pH/ORP

holder without a pH or an ORP cartridge will void the warranty.

WARNING! – Before opening analyzer

cover; switch off the analyzer line power at the circuit

breaker to avoid risk of shock. Line power is present

on terminals even when analyzer is switched off.

WARNING! – Circuit breaker meeting IEC-

947-3 must be on line supply, in close proximity to

equipment and shall be marked as the disconnecting

device for the equipment.

3. Open the enclosure of the Process Analyzer. Pass all connection cables through glands or ½”

conduit in the bottom of the enclosure (gland and conduit are not supplied). The sensor input

connections are made to terminal blocks TB1 through TB4 (labeled SENSOR 1 through 4) on the

standard unit (see drawing IIG07R111) and TB2 of the daughter boards for sensor 5 through 8.

The four wires are color coded and there is a cable shield. Connect the RED wire to the terminal

labeled “RED”. Connect the GREEN wire to the terminal labeled “GRN”. Connect the WHITE

wire to the terminal labeled “WHT”. Connect the BLACK wire to the terminal labeled “BLK”.

Connect the cable SHIELD to the terminal labeled “SHLD”. The analog outputs are available

on the terminal block labeled TB8 & TB9 and the relay outputs are available on the terminal

block labeled TB5.

4. Power Selector Switch: Check switch S2 on the circuit board to be sure that it is set for the type

of power being used (115 volts or 230 volts). Power connections should now be made to the

terminal block labeled TB6. Turn power "on" by using switch S1. Close and secure the

enclosure.

5. Switch the circuit breaker on and the unit will now power up.

6. Once the unit is turned on, the unit will initialize and then jump into the "RUN" mode and begin

displaying Channel 1 “CH 1” content on the upper left-hand portion of the display and Channel 2

through 4 content below it and Channel 5 through 8 in the right-hand column.

Note: The Model 10 D.O. sensor undergoes a thorough and

accurate test and calibration procedure before shipment

from the factory. Calibration of the D.O. reading at startup

is not necessary and is not recommended.

Analog Outputs

Four isolated 4-20 or 0-20 milliamp signals capable of driving 600 ohms are available from the

terminal block labeled “Current Outputs”. See drawing IIG07R111 for details. The #1 analog output is

labeled "I1 & C1” and the #2 analog output is labeled “I2 & C2” and so on. Each analog output may be

assigned to any sensor channel. The Analog Outputs for the add-on channels are locate on the

respective daughter boards and labeled as such.

Digital Output

A Modbus communications (RS-485) output is available from TB7 and is labeled “Modbus”. This is a

three wire signal with a transmit plus (labeled X+), a transmit minus (labeled X-), and a transmit ground

or common (labeled X COM). The Modbus interface uses 8 bits, no parity, 1 stop bit. See drawing

IIG07R111 for details. The RS-485 interface is electrically isolated from the measurement and

microprocessor circuitry of the MPA-48. The communications protocol for the Digital Output is fully

described in Appendix A.

Relay Outputs

There are four independent programmable set point control relays that may be assigned to any

sensor channel. These relays are Form-C with contacts rated 10/6 amps resistive load at 125/250 VAC.

Two Form-A relays with contacts rated 10/6 amps resistive load at 125/250 VAC are used for the jet

clean function. The connections for the relay outputs are available from TB5. See drawing IIG07R111

for connection details.

OPERATION

Note! – In “Normal Operation” the hinge

cover is to remain tightly screwed closed. Under no

circumstance is it necessary for the operator to open

the enclosure during normal operation.

RUN Mode

The RUN mode is the normal operating mode of the analyzer and is entered upon power-up. When

the Run mode is entered the analyzer will determine what types of sensors are attached to each channel.

The display is continuously updated with the current measurement values. Also, the analog output and

the relays are updated according to the current conditions and their programmed functions. In the event

of an error or alarm condition the display will indicate the problem in plain English text.

The supplied sensors have been calibrated at the factory. Sensor information for the Model 15/15L

TSS sensors are stored in non-volatile memory of the analyzer. If a Model 15/15L is connected to the

analyzer and the sensor information does not match the information stored in the analyzer, the analyzer

will display a configuration message. The configuration message for the Model 15/15L TSS sensor is

“**Zero sensor**”. These messages will appear whenever the sensor is changed.

While in the RUN Mode, the time to next scheduled clean cycle can be viewed by pressing and

holding either arrow key. A clean cycle can be demanded by pressing the ENTER key while in the RUN

Mode, see the section on Demand Clean.

MAIN MENU

The MAIN MENU is accessed by pressing the “MENU” key while in the RUN mode of operation.

There are three options available from the main menu. Use the arrow keys to switch between RUN,

SETUP, and TEST, and then press the "ENTER" key to select.

SETUP Mode

This mode of operation allows the user to customize the unit to the specific operation and needs of

the facility. There are a total of five subcategories that may be adjusted.

Operation of the SETUP MODE proceeds as follows:

From the MAIN MENU, select SETUP and the five menu options will be displayed. Use the

“ARROW” keys to move the cursor to the desired SETUP option, and then press the “ENTER” key. A

menu with five options will be displayed. The options are:

RELAYS

ANALOG OUTPUT

MODBUS

CHANNEL ENABLE

SENSOR

Pressing the “MENU” key will return to the previous page. To return to the RUN mode, press the

“MENU” key until the MAIN MENU is displayed and then press the “ENTER” key with the RUN mode

selected.

RELAYS

When the RELAYS option is selected from the SETUP menu, the operator is prompted to select

which relay is to be configured. There are five menu options for configuring the setpoint relays.

OP MODE - defines operation mode of relay as a high or low setpoint.

ON SETPOINT - defines when the relay will energize.

OFF SETPOINT - defines when the relay will de-energize.

FAIL MODE - defines the relay state during an alarm condition (no change, ON, or OFF).

CH ASSIGN - defines to which sensor the relay is assigned. A sensor may be assigned to more

than one relay.

There are four menu options for configuring the clean relays.

SYSTEM TYPE - defines what type of cleaning system is used.

CLEAN SCHEDULE - defines how often a cleaning cycle will occur.

CLEAN JET TIME - defines duration of time the clean relays will be energized.

CLEAN RECOVERY TIME - defines how long the reading holds after the clean cycle has ended.

Note: Do not attempt to adjust relay set points values until

a working sensor has been connected to the channel.

Otherwise, the analyzer may not display the correct units

(TSS or D.O.) for the channel.

Low Setpoint

If a relay “OP MODE” has been set as a LOW setpoint, then the corresponding relay will energize if

the reading falls below the value set in the “ON SETPOINT” parameter. Once the relay has been

energized by a low reading, it will not be de-energized until the reading rises above the value set in the

“OFF SETPOINT” parameter. The relay “OFF SETPOINT” value MUST be greater than or equal to the

“ON SETPOINT” value in this mode.

High Setpoint

If a relay “OP MODE” has been set as a HIGH setpoint, then the corresponding relay will energize if

the reading rises above the value set in the “ON SETPOINT” parameter. Once the relay has been

energized by a high reading, it will not be de-energized until the reading falls below the value set in the

“OFF SETPOINT” parameter. The relay “OFF SETPOINT” value MUST be less than or equal to the “ON

SETPOINT” value in this mode.

Clean Mode

The jet clean system is intended to be connected to relays “CLN 1” & “CLN 2”. The relays are

connected to an InsiteIG compressor, CA-2 and CA-4 or a customer supplied air or water source and a

shut-off valve. See drawing IIG07R113, IIG07R112, IIG07R114 and IIG07R116 for details. To program

the Clean Type go to Setup Menu – Relays – CLN Relays – System Type and select the appropriate

clean system; “CA2 Clean”, “CA4 Clean”, “House”. House clean is used for customer supplied air or

water.

The CLEAN SCHEDULE program parameter determines how often the jet clean cycle will occur.

This parameter can be set to values of 10 minutes to 24 hrs. Typically, a clean interval of 2 hrs works

well for aeration basins. In colder climates, condensation may form then freeze in the jet-clean tubing.

To prevent this, set the clean interval to 10 or 20 minutes. If this is set to “0” then cleaning is turned off.

The CLEAN JET TIME program parameter determines how long the jet clean cycle will last. The

CLEAN PULSE can be set to values of 5-seconds to 90-seconds with a 1-second resolution. Typically, a

clean pulse of 30-seconds works well for aeration basins. The analyzer will hold all the measurement

reading during the clean cycle and the recovery period which is equal to the programmed clean jet time.

In CA2 (2 channel clean system) Clean mode, a standard clean cycle will consist of the channel 1

sensor being cleaned for the programmed clean jet time immediately followed by the channel 2 sensor

being cleaned for the programmed clean jet time. For channels 3 & 4 a second CA-2 compressor can be

connected in series with the first.

In CA4 (4 channel clean system) Clean mode, the compressor is turned on for the whole duration of

the clean cycle and the MPA-48 sends a series of pulses to the compressor so each of the four sensors

will be cleaned sequentially.

In House Clean mode, both clean relays are turned on for the whole duration of the clean cycle.

The CLEAN RECOVERY parameter determines how long the analyzer will hold the DO reading after

the cleaning jet time has expired. The default setting is 1 minute which is adequate in most applications.

However, increased recovery time may be required for applications where the sensor is in stagnant

water or dead zones.

Demand Clean

When the analyzer is in the RUN mode pressing the "ENTER" button will cause a clean cycle to

begin (if the CLEAN SCHEDULE is not set to OFF). Performing demand clean doesn’t affect the normal

clean schedule.

ANALOG OUTPUT

When the ANALOG OUTPUT option is selected from the SETUP menu, the operator is prompted to

select which analog output is to be configured. There are five menu options for configuring the analog

outputs.

TYPE - selects either 4-20mA or 0-20mA operation for the analog output.

FULL SCALE - defines the value that will cause the analog output to go to 20mA.

MIN SCALE - defines the value that will cause the analog output to go to 0/4mA.

FAIL MODE - defines the value of the analog output during an alarm or error condition (no change,

full scale, or min scale).

CH ASSIGN - defines to which sensor the analog output is assigned. A sensor may be assigned to

more than one analog output.

MODBUS

There are three menu options for configuring the serial digital output.

Comm Address – defines the address of the analyzer

Comm Baud Rate – defines the baud rate of the digital output

Comm Mode - defines the communications mode as RTU or TCP

Appendix A describes the Modbus protocol implementation in the MPA-48.

CHANNEL ENABLE

When the CHANNEL ENABLE option is selected from the SETUP menu, the operator is prompted to

select which sensor channel is to be configured. The selected channel may be ENABLED or DISABLED

by pressing the “ARROW” keys and then pressing the “ENTER” key.

SENSOR SETUP

Each channel has its own sensor setup menu. The analyzer will select the appropriate menu for the

type of sensor that is currently connected to each channel.

DO Sensor

General

The Model 10 sensor has been designed to require very infrequent calibration. Unlike polaragraphic

systems, light fouling of the sensing element should not affect the accuracy of the reading, but should

only slow the response time of the system. (However, heavy biological fouling that prevents reasonable

sensor contact with the water will cause erroneous readings.) With the sensor kept reasonably clean, the

calibration should hold for 3 months to a year, depending upon conditions.

Note: The Model 10 D.O. sensor undergoes a thorough and

accurate test and calibration procedure before shipment

from the factory. Calibration of the D.O. reading at startup

is not necessary and is not recommended.

The MPA-48 analyzer allows the user to select from two different calibration procedures. The

procedure can be selected by choosing SETUP from the main menu. Once the SETUP menu appears,

use the arrow keys to choose the “SENSOR” option, and then select the desired sensor.

Sensor Calibration to a Reference

Calibration to a known reference is the easiest, simplest, and also the preferred method of calibration

when calibration is required. Calibration option number 1 “SENSOR REF CAL” allows the operator to

make adjustments to the D.O. reading to agree with any other source of D.O. information. THIS

CALIBRATION PROCEDURE MUST ONLY BE USED ON A CLEAN SENSOR. IF THE SENSOR IS

READING ERRONEOUSLY DUE TO HEAVY BIOLOGICAL FOULING, USE OF THIS CALIBRATION

METHOD WILL RESULT IN UNRELIABLE RESULTS. The sensor must be stable in the water to be

used as a reference before beginning this procedure. From the SENSOR SETUP menu, choose the

“Sensor Ref Cal” option, and press ENTER. The analyzer will now read the sensor for the period of time

indicated by the “dampening” parameter, and display the result as D.O. in PPM. If this result matches

the reference, simply press ENTER to exit. Otherwise, use the arrow keys to adjust the reading to match

the reference value, and then press ENTER to store this new value. This procedure is primarily an

adjustment to the offset value of the sensor, but an adjustment in slope will also be made when this

procedure is performed.

Sensor Slope Adjustment (NOT RECOMMENDED)

If performed correctly, the previously described “Sensor Calibration to a Reference” should be all

that is required by the user. “Sensor slope adjustment” should only be attempted upon recommendation

from the factory.

Sensor calibration option 2 “SENSOR SLOPE ADJ” allows the user to adjust the span of the sensor,

but this procedure must only be used immediately AFTER the sensor has been “zeroed” using calibration

option 1 with the sensor submerged in a zero oxygen solution. This zero solution may be prepared by

adding one tablespoon of sodium sulfite salt per liter of tap water in an open container (bucket). The

sodium sulfite salt will remove all oxygen from the water as it dissolves. Stir the water for about one

minute to dissolve the salt. Submerge the Model 10 sensor in this water and allow it to rest for at least

30 minutes. Make sure that no air bubbles are trapped on the face of the sensing element during the

soak. Once the sensor is stable, use the “Sensor Calibration to a Reference” procedure described
