Inputs
Before starting a measurement, the necessary electrodes should be
connected to the proper inputs. A separate automatic temperature
compensation is provided for each channel but a common Pt1000 (or
Pt100) thermocompensator for both channels can also be used.
Before the exact location of the electrodes is finalised, it is worthwhile to
carry out a measuring profile of the process stream to ensure that the
required homogeneity is being achieved. As a general rule the electrodes
should protrude into the process stream by one-third of the pipe width and
be positioned so as to avoid gas pockets or sediments. Generally the
measuring electrodes are inserted into the flow with the sample pick-up
facing downstream in order to reduce the risk of blockage by suspended
material. All sensors are usually positioned vertically at a suitable point
downstream of the dosing point, where the measurements are stable and
reliable. The response of the dosing system will be affected by the time
required to disperse the reagents and their arrival at the measuring point.
Sample point
Connections
Electrodes:
EC1 conductivity cell terminal (+) and (-) of (CHAN.1).
EC2 conductivity cell terminal (+) and (-) of (CHAN.2).
°C1 Pt1000 electrode to terminals (°C1).
°C2 Pt1000 electrode to terminals (°C2).

Since the instrument is directly wired to the AC power line, an external
mains switch should be provided when recommended by the local
legislation. If a mains failure has occurred, it will always automatically
proceed with the process control when the AC power comes back on.
SET-UP
Procedure to pre-set the different channels and their possibilities
according your applications.

and press CAL to continue or SET to cancel. Mode [CH.ind.] means
that both channels operate independently. Mode [CH.diF.] means that
the relays are only activated when a pre-set difference between both
channels is exceeded. Mode [CH.And.] means that both channels
must exceed a pre-set level before the relays are activated. Mode
[CH.or] means that the relays are activated when one of both
channels exceeds a pre-set level.
[CH1=EC] : Conductivity-measurement
[CH1=°C] : Temperature measurement
[CH1=OFF] : Channel switched off
Relays:
There are three relays (REL1) through (REL3) with voltage-free contacts,
which may be programmed to be activated by the high/low levels or a pre-
set alarm. The ratings of the connected load should lie between 100...250
V~, maximum 0.5 A.

or Àand press CAL to continue with all the next relays (r2...r3) or
press SET to cancel.
RS232
It is recommended to decrease the BAUD rate in case of difficulties with
the digital connections, especially for long distances.
1. Press SET.
2. Press ¿or Àuntil the display shows [SEtuP] and press CAL to
continue or SET to cancel.
3. Press CAL until the display shows e.g. [br=2400]. Pre-set the desired
baud-rate (150...4800 b/s) with ¿or Àand press CAL.
4. The display shows e.g. [rS=60] which means that data is transmitted
every 60 s during a normal measuring phase (no pre-set levels are
exceeded). Pre-set the desired time interval (0...9999 s) with ¿or À.
Pre-set to zero if not required.
5. The display shows e.g. [rS=15], while the (H) & (L) indicators are
blinking, which means that data is transmitted every 15 s when a pre-
set level is exceeded. Pre-set the desired time interval (0...9999 s)
with ¿or À. Pre-set to zero if not required.
6. Press CAL to continue or SET to cancel.
Oversampling
By using several subsequent measurements, readings become very
stable since it allows the digital filter to eliminate noise-peaks more
effectively.
1. Press SET.
2. Press ¿or Àuntil the display shows [SEtuP] and press CAL to
continue or SET to cancel.
3. Press CAL until the display shows e.g. [Sr.EC=01]. Select the desired
mV sampling rate (1...20) with ¿or À.
4. Press CAL to continue or SET to cancel.

7
Parameter
The displayed possibilities depend from the channel set-up (conductivity
or °C) and their logic function (independent, differential, AND, OR).
1. Press SET.
2. Press ¿or Àuntil the display shows e.g. [SEt PAr1] and press CAL
to continue or SET to cancel. Select [SEt PAr2] to program the
parameters of channel-2. Indicator (1) will now be replaced by (2). If
both channels have been linked by one of the logical functions, both
indicators will blink.
3. The display shows e.g. [600µS] while (1) and (L) are blinking. Pre-set
the desired low level for channel-1 with ¿or Àand press CAL to
continue or SET to cancel.
4. The display shows e.g. [800µS] while (1) and (H) are blinking. Pre-set
the desired high level for channel-1 with ¿or Àand press CAL to
continue or SET to cancel.
5. The display shows the hysteresis between the ON and OFF state of
the relays e.g. [Hy=0.10] while (1) and (=) are blinking. Pre-set the
desired hysteresis for channel-1 with ¿or Àand press CAL to
continue or SET to cancel.
6. The display shows the delay (s) after which the relays should be
activated, when one of the pre-set levels is exceeded, e.g. [dt=120]
while (1) and (=) are blinking. Pre-set the desired delay for channel-1
with ¿or Àand press CAL to continue or SET to cancel.
7. The display shows the max. level difference from which proportional
regulation should start, e.g. [dµS=80] while (1) and (=) are blinking.
Pre-set the desired difference for channel-1 with ¿or Àand press
CAL to continue or SET to cancel. Pre-set this value to zero for
simple ON/OFF regulations.
8. The display shows the pulse time (s) of the relays, e.g. [Pt=15] while
(1) and (=) are blinking. The relays will pulse at a rate proportional to
the regulation difference. When the difference is superior to the pre-
set max. value, the relay is continuously activated. However, the wait-
time between the pulses increases near the high or low pre-set level.
Pre-set the desired pulse-time for channel-1 with ¿or Àand press
CAL to continue or SET to cancel. This step is skipped for simple
ON/OFF regulations.
9. The display shows the alarm time (s) after which the process control
should be interrupted in case of a failure, e.g. [At=360] while (1) and
(=) are blinking. Pre-set the desired alarm-time for channel-1 with ¿
or Àand press CAL to continue or SET to cancel. Pre-set this value
to zero if no alarm is required.
10. When both channels are linked to each other by an AND or an OR
function, the display shows the maximum allowed difference between
the 2 measurements, e.g. [dA=0.30] while (1), (2), and (=) are
blinking. Pre-set the desired value with ¿or Àand press CAL to
continue or SET to cancel. The process control is immediately
stopped and a general alarm is given should this value be exceeded.
The differential function between both channels permits to control a
process on the difference between two measured values. A high level
pre-set of e.g. 300 µS causes the relevant relay to be activated only
when the difference in conductivity between both channels exceeds 300
µS and NOT when one of the channels exceeds 300 µS!

The instrument can be identified by e.g. a computer when a specific
number is allocated to it.
1. Press SET.
2. Press ¿or Àuntil the display shows [SEtuP] and press CAL to
continue or SET to cancel.
3. Press CAL until the display shows e.g. [Id.no=5]. Pre-set the desired
identification number (0...999) for your meter with ¿or À. Pre-set to
zero when not relevant.
4. Press CAL to continue or SET to cancel.
Identification
A private code can be programmed to avoid undesired access to the
instrument.
1. Press SET.
2. Press ¿or Àuntil the display shows [SEtuP] and press CAL to
continue or SET to cancel.
3. Press CAL until the display shows [Code on], [Code OFF], or [Code
CAL]. Decide whether the access to all future calibrations should be
by entering a code (on) or not (off) and press CAL. Select [Code CAL]
to enter your personal code.
4. The display shows [E=-----] while [=] is blinking. Enter your secret
sequence of 5 keys to proceed.
If [Code on] has been programmed after a general reset without
entering first a personal code, the factory pre-set (5 x SET) is
automatically valid.

MEASUREMENT
Calibration
This controller is provided with both a normal automatic calibration and a
special rapid shift procedure. This is of considerable benefit for those
cases where it is not so easy to remove the cells for a normal calibration.
While the usual cell constant determination is normally made during an
important maintenance, when the cells have to be removed anyway, a
daily calibration can be performed without removing the cells from their
fittings. The latter requires only an extra portable meter to measure the
real conductivity or °C values of the processed liquid, whereafter these
values are introduced into the controller for a rapid automatic calibration
(shift). Note that not only the conductivity ranges but also the °C
ranges can be calibrated with this rapid procedure!

Automatic
conductivity
calibration
1. Select the desired conductivity channel with ¿or Àand press CAL.
2. Remove the cell from its fitting and rinse it with distilled water. After
rinsing the cell several times with the standard solution, immerse it in
that standard.The solution temperature is not so critical but should lie
between 0°C and 30°C.
3. Press ¿or Àuntil the display shows [Auto] and press CAL to start
the automatic calibration procedure.
4. The display shows one of the KCl standard solutions in memory
[St=0.01M], [St=0.1M], or [St=1M]. Select the proper standard with ¿
or Àand press CAL.
5. The display will show the computed cell constant e.g. [cc=1.045] and
will calibrate automatically when readings are stable ([=] stops
blinking and e.g. [µS=1413] is shown). Press CAL to continu or press
SET to cancel.
6. After rinsing the cell with distilled water, insert it back in its fitting and
start the EC control.
∗Read temperature by pressing ¿or À.
∗The instrument will refuse automatic standardisation when readings
are unstable.
The cell constant depends on the physical dimensions of the platinum
plates, which are coated with a spongy black platinum deposit. This
increases greatly the effective surface and reduces polarising effects.
Since the coating of platinum black is quite resistant to chemical action,
the cell constant remains fairly constant during the electrode life time.
1. Select the desired conductivity channel with ¿or Àand press CAL.
2. Verify if the attached cell is completely dry.
3. Press ¿or Àuntil the display shows [COMP] and press CAL to start
the automatic compensation procedure.
4. The display will show [COMP.on] or [COMP.OFF]. Select [COMP.on]
with ¿or Àand press CAL to start the automatic capacitance
compensation. The display will show [WAit] for a while.
5. Press SET to continu.

1. Select the desired conductivity channel with ¿or Àand press CAL.
2. Measure the real conductivity value of processed liquid with an other
electrode and meter.
3. Press ¿or Àuntil the display shows [ShiFt] and press CAL to start
the automatic calibration procedure.
4. The display shows e.g. [µS=713] while [=] is blinking as long as
readings are not stable. Shift to the real value with ¿or À, when [=]
stops blinking, and press CAL to return to the measurements. Press
SET here if you wish to return to the original readings.

Computer
connection
Interfacing with a computer:
Any desired command can be included in a computer data acquisition
program. Follow exactly the same measuring or calibration procedures as
described in this manual. The instrument is able to recognise commands
in two ways:
Simple: the simple method can be used when only one controller is
connected to the computer (identification number should be zero!). Send
a single character to the instrument and it will immediately execute the
corresponding command as follows:
1 = press SET.
2 = press ¿.
3 = press À.
4 = press CAL.
? = send display to computer.
+ = keyboard on (manual operation remains possible).
- = keyboard off (manual operation disabled).
V = start the input of a value (only valid in certain routines).
This example makes the computer press SET in the simple mode:
10 OPEN "COM1:2400,N,8,2" AS #1 'prepares communication port
20 PRINT #1,"1" 'SET key pressed
Sophisticated: this method is used for all types of communications such
as a network of several R300's connected to the computer. The
commands should always be preceded by the identification number of the
controller concerned (see Set-up):
#xxx = "#" + identification number (xxx) in ASCII code. All blank (ASCII-
32) or CR (ASCII-13) characters following the identification
number are ignored!
C1 = press SET.
C2 = press ¿.
C3 = press À.
C4 = press CAL.
C? = send display to computer.
C+ = keyboard on (manual operation remains possible).
C- = keyboard off (manual operation disabled).
V = start the input of a value (only valid in certain routines).
LF = linefeed (ASCII-10), closes a command or input and permits the
instrument to receive a next command.

12
This example makes the computer press SET on controller #7, in the
sophisticated mode:
10 OPEN "COM1:2400,N,8,2" AS #1 'prepares communication port
20 PRINT #1,"#007"; 'identification number 7
30 PRINT #1,"C1"; 'SET key pressed
40 PRINT #1,CHR$(10); 'LF, command closed
Input of a value: the direct input of values ("V" command) is only possible
when the instrument is running a routine where also a manual input of
these values could be made. If not, it will ignore any "V" command from
the computer!
Examples of allowed routines are:
∗temperature input (e.g. manual temperature compensation).
∗control parameter input such as Low, High, ...
∗time settings.
∗input of manual buffer values.
Examples of NOT allowed routines are:
∗during measurements or controls.
∗when values have to be selected rather than changed (e.g. buffer
values in memory).
∗while an electrode is being calibrated.
A 16-bit value (2's complement) should be transmitted in the following
sequence:
1st character = "V" (start a value input)
2nd character = highest byte of the value in ASCII
3rd character = lowest byte of the value in ASCII
4th character = checksum of 2nd and 3rd character in ASCII
5th character = LF, linefeed (ASCII-10)
When a correct checksum has been received, the instrument will send a
confirmation character "!" to the computer. If not, a question mark "?" is
sent. Both are eventually preceded by the identification number.
This example makes the computer to enter the value "1000" on controller
#7, in the sophisticated mode:
1000 = (H-byte 3)(x 256) + (L-byte 232)
10 OPEN "COM1:2400,N,8,2" AS #1 'prepares communication port
20 PRINT #1,"#007"; 'identification number 7
30 PRINT #1,"V"; 'start a value input
40 PRINT #1,CHR$(3); 'highest byte of value
50 PRINT #1,CHR$(232); 'lowest byte of value
60 PRINT #1,CHR$(235); 'checksum of both bytes
70 PRINT #1,CHR$(10); 'LF, closes command

Foutmeldingen
De aflezing wisselt automatisch (±4 s interval) tussen de gekozen
meetbereiken door tegelijkertijd op ¿en Àte drukken tot [ALt]
verschijnt.
Ingangen
Alvorens een meting te doen, moeten de juiste elektroden met de juiste
ingangen worden verbonden. Er is een afzonderlijke automatische
temperatuurcompensatie voor elk kanaal, maar er kan ook een
gemeenschappelijke temperatuurcompensator Pt1000 (of Pt100) gebruikt
worden voor de twee kanalen.
Meetpunt
Vooraleer een definitieve keuze wordt gemaakt i.v.m. de plaats van de
elektroden, is het nuttig een meetprofiel te maken van de vloeistofstroom
om zeker te zijn dat de vereiste homogeniteit bereikt is. De regel wil dat
de elektroden één derde van de buiswijdte diep in de vloeistofstroom
steken en zo geplaatst worden dat zij gasbellen of bezinksel rond het
meetpunt vermijden. Gewoonlijk worden de meetelektroden vertikaal in de
stroming geplaatst met de meetkop stroomafwaarts gericht om het risico
voor verstopping door zwevend materiaal in te dijken. Alle sensoren
worden meestal geplaatst op een geschikte plaats stroomafwaarts van
het doseerpunt, waar de metingen stabiel en betrouwbaar zijn. De
respons van het doseersysteem wordt beïnvloed door de tijd die nodig is
om de reagentia te verspreiden en hun aankomst bij het meetpunt.
Verbindingen
Elektroden:
EC1 geleidbaarheidscel aan klem (+) en (-) van (CHAN.1).
EC2 geleidbaarheidscel aan klem (+) en (-) van (CHAN.2).

°C2 Pt1000 temperatuurcompensator aan klemmen (°C2).

Omdat het toestel rechtstreeks aangesloten is op het net, moet het
voorzien zijn van een externe schakelaar indien de lokale wetgeving dit
vereist. Mocht er een netstoring optreden, zal het toestel altijd auto-
matisch verdergaan met de regeling wanneer de spanning weerkeert.
Netspanning:
fase aan klem (P).
neutraal aan klem (N).
aarde aan aardingsklem
Relais:
Er zijn drie relais (REL1...REL3) met spanningsvrije contacten die zo
geprogrammeerd kunnen worden dat zij in werking treden bij
overschrijding van de laag/hoog-niveaus of bij alarm. De aangesloten
belasting moet tussen 100...250 V~, max. 0,5 A, liggen.
