Description of the System
This instrument is applicable for the measurement of the pH
respectively ORP value in water.
Application
range
Measuring
Principle
Temperature
compensation
pH and redox (ORP) is measured in many different applications:
Š swimming pools
Š waste water
Š high purity water
Š power plants (steam, condensate)
Š industry
Depending on the application, different electrode types and flow
cells/fittings are needed.
pH: The electrode consists of a pH sensitive glass electrode and a
reference electrode = measuring chain. Depending on the pH value
in the water, the mV value of the measuring chain changes. If both
electrodes are integrated into one shaft it is a combined electrode.
Reference electrodes are available with gel (Swansensor pH for
potable water and swimming pools, Swansensor pH AY for waste
water) or with liquid electrolyte (Swansensor pH SI for power plant
cycle, Swansensor pH FL for high purity water).
ORP: The electrode consists of a platinum pin and a reference
electrode = measuring chain. Depending on the ORP value in the
water, the mV value of the measuring chain changes. If both
electrodes are integrated into one shaft it is a combined electrode.
Reference electrodes are available with gel (Swansensor pH for
potable water and swimming pools, Swansensor pH AY for waste
water) or with liquid electrolyte (Swansensor ORP SI for power
plant cycle, Swansensor ORP FL for high purity water).
pH: The pH value depends on temperature. If the temperature of
the sample is not stable, we recommend to install a temperature
sensor. If no temperature sensor is chosen, please program the
temperature of the sample in the instrument.
For high purity water applications (power plant, high purity water):
Additionally to the Nernst compensation a non-linear solution
compensation or linear compensation with coefficient can be
chosen.
ORP: Temperature compensation is not necessary.

inside. Release air bubbles in the electrolyte tube by knocking on it.
- Insert the electrode into the flow cell and fasten hand-tight.
- Cut off the tip of the electrolyte bottle. Take the plug out of the
electrolyte tube. Put the electrolyte bottle firmly on the tube.
- Mount the electrolyte bottle in the click holder (see 2.3 Instrument
overview, p. 11).
- Puncture the electrolyte bottle to allow pressure equilibration.
- Take off plug cap. Connect to sensor cable. Store caps.
UNIDIP fitting Please refer to the manual of the UNIDIP fitting how to install the pH/
ORP electrode and the temperature sensor in detail. Ensure that all surfaces and o-rings are clean. If mounted correctly, the UNIDIP fitting is
tight. No water is allowed inside the UNIDIP fitting. Otherwise the cables
corrode. If you use an UNIDIP Rinsematic, make sure the nozzles face
the pH/ORP sensor.

4 Operation
4.1 Sensors
4.1.1 Filter time constant:
Used to flatten noisy signals. The longer the filter time constant, the
slower the system reacts to changes in the measuring value.
Scalable values: 5-300 sec
4.1.2 Hold after calibration:
Delay to enable the instrument to stabilize again after calibration, so no
peaks show up on the signal output and no false limit warnings are
issued. During calibration and hold after calibration, the signal outputs
are frozen (held on last valid value), alarm values, limits are not active.
Scalable values: 5 - 6000 sec
4.2 Relay contacts
4.2.1 Alarm relay:
Here you reprogram alarm values high and low.
Alarm:
Alarm high: The measuring value must not rise above the alarm high
value, set in this menu. Otherwise the alarm relay closes and E001 is
issued. Scalable values: 0.00 - 14.00 pH, -500 to 1500 mV.
Alarm low: If the measuring value falls below the alarm low value, set in
this menu, the alarm relay closes and E002 is issued. Scalable values:
0.00 - 14.00 pH, -500 to 1500 mV.
A-96.250.441 / 060923
35
AMU pH-Redox
Appendix
Hysteresis: Within the hysteresis area, the relay does not open if the
alarm has been active. Used to prevent unnecessary relay switching
(damage), which occurs if the measuring value fluctuates around the
alarm value. Scalable values: 0.00 - 14.00 pH, -500 to 1500 mV.
Delay: The time, the activation of the relay is retarded after the
measuring value has risen above/fallen below the programmed alarm.
Scalable values: 0-28800 sec.
4.2.2 and Relay 1 and 2:
4.2.3 Here you reprogram the limit value or set-point of control, or redefine
the timer function. The available parameters depend on presetting in
Installation.
Limit upper/lower:
Set-point: If the measuring value rises above (upper limit) respectively
falls below (lower limit) the set-point, the relay closes.
Hysteresis: Within the hysteresis area, (below limit upper respectively
above limit lower), the relay does not open if the limit has been
exceeded. Used to prevent unnecessary relay switching (damage),
which occurs if the measuring value fluctuates around the limit value.
Delay: The time, the activation of the relay is retarded after the
measuring value has risen above/ fallen below the limit value.
Control: To maintain a certain set-point in the system.
Control upwards: Rises the measuring value to the set-point, assisted
by a control device. E.g. dosing alcaline solution with a pump to rise pH
value.
Control downwards: Lowers the measuring value with the help of a
control device, e.g. dosing acid with a pump into a swimming pool.
Set-point: Program the required value which should be maintained in
the system.
P-Band: Area, above (downwards control) or below (upwards control)
the set-point, where the dosing intensity is reduced from 100% to 0%,
to equal set-point without overshooting.
Timer: Relay closes as programmed, e.g. to issue the cleaning of the
instrument.
Mode: Set how often the relay should close. Choose between interval
or daily or weekly
If interval is chosen: Choose the time interval. Scalable values: 1 1440 min.
If daily is chosen: The contact closes once per day. Set the starting
time.
If weekly is chosen: Program the starting time and the active days. The
timer function starts on all days set to On.
Run Time: For all modes. Time, how long the relay closes. Scalable

5.3 Relay contacts
5.3.1 Alarm relay:
Here you set the alarm values for the measuring value, temperature,
sample flow, case temperature.
5.3.1.1 Alarm measuring value: Define the measuring value, which should
issue an alarm high respectively low.
Alarm high: The measuring value must not rise above the alarm high
value, set in this menu. Otherwise, the alarm relay closes and E001 is
issued. Scalable values: -3.00 - 15.00 ppm, -500 - 1500 mV
Alarm low: If the measuring value falls below the set alarm value, the
alarm relay closes and E002 is issued.
Scalable values: -3.00 - 15.00 ppm, -500 - 1500 mV
Hysteresis disinfectant: Within the hysteresis area, the relay does not
open if the alarm has been active. Used to prevent unnecessary relay
switching (damage), if the measuring value fluctuates around the alarm
value. Scalable values: -3.00 - 15.00 ppm, -500 - 1500 mV
Delay: The time, the closing of the alarm relay is retarded after the
measuring value has risen above/fallen below the alarm value.
Scalable values: 0-28800 sec

5.3.1.3 Alarm sample flow: Here you define at which sample flow a flow alarm
should be issued and if the alarm relay should close.
Alarm flow high: If measuring value rises above the programmed
value, E009 flow alarm high will be issued. Scalable values: 10-50l/h
Alarm flow low: If the measuring value falls below the programmed
value, E010 flow alarm low will be issued. Scalable values: 0-9 l/h
5.3.1.4 Alarm Sample Temperature: Only if temp. senor has been connected.
Alarm high: If the temperature rises above the programmed value,
E007 is issued. Scalable values: -25 - 250 °C
Alarm low: If the temperature falls below the programmed value, E008
is issued. Scalable values: -25 - 250 °C
5.3.1.5 Case temp. high: Set the alarm high value for temperature of
electronics housing. If the temperature rises above the programmed
value, E013 is issued. Scalable values: 30 to 75 °C
5.3.1.6 Case temp. low: Define the alarm low value for temperature of
electronics housing. If the measuring value falls below the
programmed value, E014 is issued. Scalable values: -10 to +20 °C
5.3.2 and Relay 1 and Relay 2
5.3.3 Program the function of the relays in detail.
5.3.2.1 and Function: Choose if the relay should
5.3.3.1 - close if the measuring value rises above/falls below the set limit,
- if it should drive a control device (pump, motor valve, etc.) to maintain
a certain set-point,
- if it is used as timer (e.g. adding sensor cleaning solution),
- if it should be activated by Profibus DP.
Available settings: Limit upper/lower/control upwards/control
downwards/timer/fieldbus

Appendix
Limit upper/ See also graphic on page 63.
lower: Set-point: If the measuring value rises above (limit upper) respectively
falls below (limit lower) the set limit, the relay closes.
Hysteresis: Within the hysteresis area (below limit upper respectively
above limit lower), the relay does not open if the limit has been active.
Used to prevent unnecessary relay switching (damage), which occurs
if the measuring value fluctuates around the limit value.
Delay: The time, the closing of the relay is retarded after the measuring
value has risen above/fallen below the limit value.
Control To maintain a certain set-point in the system.
Control upwards: Rises the measuring value to the set-point, assisted
by a control device.
Control downwards: Lowers the measuring value to the set-point aided
by a control device.
Control parameters PID
Set-point: Program the required value which should be maintained
constant in the system.
P-Band: Area, above (downwards control) or below (upwards control)
the set-point, where the dosing intensity is reduced from 100% to 0%,
to equal set-point without overshooting.
See also graphic on page 53
PI controller: Reset time: The controller action increases the higher the
deviation from the set-point is and the longer it lasts.
PD controller: Derivative time: The controller action increases the
higher the deviation from the set-point is and the faster the measuring
value changes.
Control If the controller action (dosing intensity) is constantly over 90% during
time-out the control time-out (in min.), without the measuring value changing
into the direction of set-point, dosing will be stopped for safety reasons,
and an alarm is issued.
Control Time The control device is driven by switching on/off its power supply. Define
proportional a time interval (cycle time) as time base for control. To reduce the
dosing intensity in the p-band, the pump runs only part-time of the
cycle.
Cycle time: Defines in which interval the pump is switched on.
Response time: To avoid stressing the control device. Minimum time,
the dosing unit has to run to avoid damage, or that elapses from the
activation until the actual dosing starts.
See also graphic below.
Control by The pump is driven by adjusting the number of pulses. The relay
frequency closes/opens in the pulse frequency.
A-96.250.441 / 060923
43
AMU pH-Redox
Appendix
Frequency: Program the number of pulses/min. the pump can handle.
Within the p-band the pulse number is reduced = dosing is reduced.
Control Only one motor valve can be connected, because both relays are
motor valve needed to work the valve. Relay 1 opens, and relay 2 closes the valve.
Program the run time and neutral zone of your motor valve.
Run time: Time, the motor valve needs to close/open completely.
Neutral zone: Within the neutral zone the controller does not react to
deviations. Unnecessary switching (damage) is avoided.

Disposal considerations
Product:
There are no uniform EC regulations for the disposal of chemicals or residues. Chemical residues
generally count as special waste. The disposal of the latter is regulated in the EC member countries
through corresponding laws and regulations, and in Switzerland also by the cantons. We recommend
that you contact either the authorities in charge or approved waste disposal companies which will
advise you on how to dispose of special waste.
Packaging:
Disposal in compliance with official regulations. Handle contaminated packaging in the same way as the
substance itself. If not officially specified differently, non-contaminated packaging may be treated like
household waste or recycled.
