measure between pH - Cl

- mV - NTU - Temperature. Customized version includes: potentiostat (mg/l Cl2) and Fluorine (F)

Once into “measure submenu”*, is possible to edit (all or some) the following setpoint parameters:

[Da] “setpoint output A” that can be congured as on/off, PWM or PID and settable as 1 to 6 channel

[Db] “setpoint output B” that can be congured as on/off, PWM or PID and settable as 1 to 6 channel

[Pa] “proportional pump output A” and settable as 1 to 6 channel

[Pb] “proportional pump output B” and settable as 1 to 6 channel

[mA] “mA output” settable as 1 to 6 channel

[Aa] “general alarm A” for “out of limits” reading parameters

[Ab] “general alarm B” for “out of limits” reading parameters

[Ad] “general alarm” for maximum dosing time

[Ar] “general alarm” for damaged probe (same reading after a set time)

Total amount of output-channels available is 6. This number decreases every time a channel is assigned to a specic function during setup. Once there are no more channels available the instrument will read only probe’s value. For temperature channel is available ON/OFF mode only during setpoint setup.

Da and Db.

Using Da and / or Db is possible to control the status of “setpoint outputs” and “level outputs” based on some rules. Refer to “power connections” and “I/O connections” blocks at page 4 and 5 to locate these outputs on mainboard.

Once that Da or Db function is enabled (move wheel over “disable” , press, rotate to “enable”, press again to exit) the

main parameters are

MODE (ON/OFF - PWM - PID), RL, LEV and STOP.

Da and Db WORKING MODES.

ON/OFF Mode.

On/Off mode set the instrument to operate using two set values that enable or disable the related setpoint output. Parameters to set for this mode are:

ON: Activate RL and LEV on moving towards the unit value (for example: pH) OFF: Disable RL and LEV on moving towards the unit value (for example: pH)

IN: assign “input” number then edit the name by moving wheel. If the “input” number is already used then it will not be

shown. Choose “X” instead of a number to disable input.

RL: assign “relay” number then edit the name by moving wheel. If the “relay” number is already used then it will not be

shown. Choose “X” instead of a number to disable relay.

STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.

“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)

MSG: when agged an SMS or EMAIL alarm message will be sent to destination edited in GSM menu.

ON/OFF mode while dosing ALKALI

Set pH value at 6.90 ON and 7.00 OFF. Instrument will leave related output active until reading value will increase up to 7.00pH. At 7.00pH the related output will be disabled until reading value will decrease under 6.90pH.

ON/OFF mode while dosing ACID

Set pH value at 7.00 OFF and 7.10 ON. Instrument will leave related output active until reading value will decrease up to 7.00pH At 7.00pH the related output will be disabled until reading value will increase up to 7.10pH.

g. 5

PWM Mode.

Pulse-width modulation (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load.

This mode works over a settable (0 to 100 seconds) time to switch on or off selected output. Time resolution is 5 seconds, 5 steps. During this time if reading value will move towards a set value (on or off) the PWM will operate the output on timered basis. Reaching the set value the PWM will permanently leave on or off the output.

Parameters to set for this mode are: Unit Value + %: (time activity towards set value. 0% means 0 seconds. 100% means 100 seconds.)

IN: assign “input” number then edit the name by moving wheel. If the “input” number is already used then it will not be

shown. Choose “X” instead of a number to disable input.

RL: assign “relay” number then edit the name by moving wheel. If the “relay” number is already used then it will not be

shown. Choose “X” instead of a number to disable relay.

STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.

“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)

MSG: when agged an SMS or EMAIL alarm message will be sent to destination edited in GSM menu.

For example: set rst pH value at 10.00 = 100% and second pH value at 5.0 = 0%. For reading values ≥ to 10.00 the output will be permanently ON. For reading values ≤ 5.0 the output will be permanently OFF.

For reading value of 9.50 the output will be OFF for 10 seconds, ON for 90 seconds.

If reading value decreases to 8.00 then the output will be OFF for 20 seconds, ON for 80 seconds.

Notes: for values within 1% and 5% MAX5 will assume 5% as usable value.

for values within 95% and 99% MAX5 will assume 95% as usable value.

g. 5

PID Mode.

A proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism. PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly.

The PID controller calculation (algorithm) involves three separate parameters; the Proportional, the Integral and Derivative values. The Proportional value determines the reaction to the current error, the Integral determines the reaction based on the sum of recent errors and the Derivative determines the reaction to the rate at which the error has

been changing. The weighted sum of these three actions is used to adjust the process. By “tuning” the three constants in the PID controller algorithm the PID can provide control action designed for specic process requirements. The

response of the controller can be described in terms of the responsiveness of the controller to an error, the degree to which the controller overshoots the setpoint and the degree of system oscillation. Note that the use of the PID algorithm for control does not guarantee optimal control of the system or system stability.

) is the constant proportional gain

) is the constant integral gain

) is the constant derivative gain

(e): error

(t): Time in the past contributing to the integral response

Parameters to set for this mode are:

IN: assign “input” number then edit the name by moving wheel. If the “input” number is already used then it will not be

shown. Choose “X” instead of a number to disable input.

RL: assign “relay” number then edit the name by moving wheel. If the “relay” number is already used then it will not be

shown. Choose “X” instead of a number to disable relay.

STOP: (“ON”: when product into tank is ending, then the related output will be off and an alarm condition will pop-up.

“OFF”: when product into tank is ending, then the related output will continue to stay on and an alarm condition will pop-up.)

ON: Activate RL and LEV on moving proportionally towards the unit value (for example: pH) OFF: Disable RL and LEV on moving proportionally towards the unit value (for example: pH) I: integral time (from 0s to 59m:59s) D: derivative time (from 0s to 59m:59s)

Conductivity calibration procedure involves a zero calibration (1st point calib) and a 2nd calibration point that requires

a buffer solution with value near working range. During this procedure probe must be dry and clean and not installed in

plant. Once into “Calibration uS” menu move wheel on “Calib 1st Pt” then press wheel, move cursor on “OK” and press

wheel again.

Move wheel on “Calib 2nd Pt” then press wheel to enter into second point calibration submenu. Prepare buffer solution

and dip probe’s sensor on it. Wait until reading value is stable and according to buffer solution value move wheel until it

is the same on display (“uS default” eld). End procedure moving cursor on “OK”

This procedure assumes that instrument is correctly congured. Otherwise unattended results may occurr.

4) Move cursor on “Comp Auto” then press wheel. Rotate wheel to Enable or disable automatic temperature compensation. Enabling this option will override “Select Temp” setup then move cursor on “ESC” or “OK” and press wheel to conrm.

5) Move cursor on “Temp Coeff” then press wheel. This option set conductivity % variation based on temperature. To disable it enter 0.0 % as value. Move cursor on “ESC” or “OK” and press wheel to conrm.

6) Move cursor on “Select Temp” then press wheel. If a temperature probe is not connected, pool temperature must be set manually. Rotate wheel to set it and conrm by pressing wheel. Move cursor on “ESC” or “OK” and press wheel to conrm.

Measurement temperature has a signicant inuence on conductivity readings; but appropriate temperature compensation is a powerful tool to allow meaningful comparison of

readings taken at different temperatures. The analyst must ensure that the type of temperature compensation utilized is appropriate for both the type of sample being analyzed

and the required test accuracy. This is an essential factor for determining the suitability of a conductivity instrument for measurement applications. A conductivity measurement

taken with the sample at the reference temperature will always be more accurate than a temperature compensated reading taken away from the reference temperature – this

point is essential for critical applications requiring high accuracy of measurements.

What is a static IP address/dynamic IP address?

A static IP address is a number (in the form of a dotted quad) that is assigned to a computer by an Internet service provider (ISP) to be its permanent address on the Internet. Computers use IP addresses to locate and talk to each other on the Internet, much the same way people use phone numbers to locate and talk to one another on the telephone. When you want to visit whatis.com, your computer asks a domain name system (DNS) server (think telephone information operator) for the correct dotted quad number (think phone number) for whatis.com and your computer uses the answer it receives to connect to the whatis.com server. It would be simple if every computer that connects to the Internet could have its own static IP number, but when the Internet was rst conceived, the architects didn’t foresee the need for an unlimited number of IP addresses. Consequently, there are not enough IP numbers to go around. To get around that problem, many Internet service providers limit the number of static IP addresses they allocate, and economize on the remaining number of IP addresses they possess by temporarily assigning an IP address to a requesting Dynamic Host Conguration Protocol (DHCP) computer from a pool of IP addresses. The temporary IP address is called a dynamic IP address.

Requesting DHCP computers receive a dynamic IP address (think temporary phone number) for the duration of that Internet ses-

sion or for some other specied amount of time. Once the user disconnects from the Internet, their dynamic IP address goes back into the IP address pool so it can be assigned to another user. Even if the user reconnects immediately, odds are they will not be

assigned the same IP address from the pool. To keep our telephone telephone analogy going, using a dynamic IP address is simi-

lar to using a pay phone. Unless there is a reason to receive a call, the user does not care what number he or she is calling from.

There are times, however, when users who connect to the Internet using dynamic IP wish to allow other computers to locate them. Perhaps they want to use CU-SeeMe or use a VoIP application to make long distance phone calls using their IP connection. In that case, they would need a static IP address. The user has two choices; they can contact their ISP and request a static IP address, or they can use a dynamic DNS service. Either choice will probably involve an additional monthly fee.

Using a dynamic DNS service works as if there was an old-fashioned telephone message service at your computer’s disposal. When a user registers with a DNS service and connects to the Internet with a dynamic IP address, the user’s computer contacts the DNS service and lets them know what IP address it has been assigned from the pool; the service works with the DNS server to forward the correct address to the requesting DHCP computer. (Think of calling the message service and saying “Hi. I can be reached at 435.44.32.111 right now. Please tell anyone who tries to reach me to call that number.) Using a dynamic DNS service to arrange for computers to nd you even though you are using a dynamic IP address is the next-best thing to having a static IP.

Appendix E - EOLUM Probe Setup and calibration

To correctly use the dissolved oxygen (ﬂuorescence membrane) probe perform calibration as described.

At ﬁrst start-up, sensor calibration is required in order to the measuring system to be able to generate accurate measuring values. The slope calibration of the oxygen sensor can be performed in air, saturated water or using a reference solution.

Calibration in AIR.

Calibration in air is only possible if air temperature is ≥-5 °C (≥23 °F). From calibration menu choose “Calib Chxx LDO”. Choose “RANGE” to setup reading scale. Choose “AIR” as calibration method. Remove sensor from the medium and dry completely. Leave it in air. Start calibration by clicking on “START”. Reading value is real time displayed on upper screen side. 600s means how many seconds are left until the end of procedure. Move cursor on “OK” when “CALIBRATION OK” message appears. If an error message appears repeat procedure.

Calibration in air saturated WATER.

From calibration menu choose “Calib Chxx LDO”. Choose “RANGE” to setup visulization scale. Choose “WATER” as calibration method. Dip head’s probe into water. Start calibration by clicking on “START”. Reading value is real time displayed on upper screen side. Time shown is how many seconds are left to the end of procedure. Move cursor on “OK” when “CALIBRATION OK” message appears. If an error message appears repeat procedure.

Calibration using a REFERENCE solution.

From calibration menu choose “Calib Chxx LDO”. Choose “RANGE” to setup visulization scale. Choose “REF” as calibration method. Dip sensor’s probe into reference solution. Start calibration by clicking on “START”. Reading value is real time displayed on upper screen side. Time shown is how many seconds are left to the end of procedure. Move cursor on “OK” when “CALIBRATION OK” message appears. If an error message appears repeat procedure.

Probe’s temperature sensor calibration.

Temperature calibration needs an external thermometer to match probe’s reading value.

From “Calib CHxx LDO menu, move wheel on “Temp”, press wheel to enter system temperature obtained from a ther-

mometer. Press wheel to conrm then move cursor on “OK” and press wheel. End procedure by moving cursor on “Exit” from “Temp” main menu and press it. If an error occurred during calibration procedure then the instrument will show an

error message and will ask to proceed to a new calibration, cancel current operation or restore default settings.

To restore probe’s calibration parameters to factory values select “FACTORY DEFAULT” within “Default” menu.

Power cycling off then on the instrument to properly save probe new calibration values.

Appendix F - MODBUS Setup

Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Simple and robust, it has since become a de facto standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices.

From main menu select COMMUNICATION then MODBUS to access the options. Set the communication speed according to the PLC system available. Set the ID assigning an UNIQUE address to avoid conﬂicts.
