1.3. Restrictions for use
The AMI Rescon is designed for determination of specific conductivity or resistivity in high purity water.
To avoid clogging the flow cell, prevent sand, oil or solids, from entering into the flow cell.
Sufficient sample flow is coercive for the correct function of the instrument. To determine values near 18.18 MOhm-cm exactly, a
sample flow of 70–100 l/h is needed.

2. Product Description
2.1. Description of the System
This instrument is applicable for the determination of specific resistivity or specific conductivity in high purity water.
Measuring
Principle
The resistivity of high purity water is determined with a sensor consisting of two metal electrodes. The characteristics of each sensor
is expressed as cell constant. An alternating voltage (to minimize
polarization effects) is applied to two electrodes. Depending on the
concentration of ions in the sample, a signal results between the
electrodes which is proportional to the resistivity of the water.
The measuring result is indicated as resistivity or conductivity. The
conductivity measurement depends on temperature, as the mobility
of ions increase with rising temperature. To eliminate these effects,
the temperature is determined simultaneous with an incorporated
NT5K temperature sensor. Several temperature compensation
curves for different applications are available.
Signal
Outputs
Two signal outputs programmable for measured values (freely scalable, linear, bilinear, log) or as continuous control output (control
parameters programmable).
Current loop: 0/4 –20 mA
Maximal burden: 510 Ω
Third signal output available as an option. The third signal output
can be operated as a current source or as a current sink (selectable
via switch).
Relays Two potential-free contacts programmable as limit switches for
measuring values, controllers or timer for system cleaning with automatic hold function.
Maximum load: 1 A/ 250 VAC
Alarm Relay One potential free contact.
Alternatively:
Open during normal operation, closed on error and loss of
power.
Closed during normal operation, open on error and loss of
power.
Summary alarm indication for programmable alarm values and instrument faults.

Safety
Features
No data loss after power failure. All data is saved in non-volatile
memory.
Over voltage protection of in- and outputs.
Galvanic separation of measuring inputs and signal outputs.
Standard
flow cell
A QV-Hflow flow cell is supplied with the Monitor as standard.
USP Operat-
ing Mode
The USP Operating Mode implemented in the firmware of the AMI
Rescon transmitter allows the measurement of pharmaceutical water according to the USP <645>.
If the USP Operating Mode is set to <off> conductivity or resistivity
standard measurement with automatic temperature compensation
is performed.
If the USP Operating Mode is set to <on>, the temperature compensation function is disabled. The uncompensated measuring values are compared with the values of an implemented table defined
by USP (see table below). If the deviation of the measured values
is too high, the Error 15 (USP Error) is issued.

QC-Kit Test
Plug
The implemented Transmitter Test together with Conductivity QCKit Test Plug containing a traceable high precision resistor allows to
perform a verification of he measuring electronics at any time.
Fluidics The flow cell QV-Hflow consists of the flow cell block [D], the flow
sensor [B] and the flow regulating valve [E].
The conductivity sensor RC-U [A] with integrated temperature sen-
sor is screwed into the flow cell block [D].
The sample enters at the sample inlet [F]. It flows through the flow
regulating valve [E], where the flow rate can be adjusted. Then the
sample flows through the flow cell block [D] were the resistivity of
the sample is measured.
The sample leaves the flow cell block via flow meter through the
sample outlet [C].

CAUTION
Risk of damage of the relays in the AMI Transmitter due to
heavy inductive load.
Heavy inductive or directly controlled loads (solenoid valves,
dosing pumps) may destroy the relay contacts.
To switch inductive loads > 0.1 A use an AMI relay box avail-
able as an option or suitable external power relays.
Inductive load Small inductive loads (max 0.1A) as for example the coil of a power
relay can be switched directly. To avoid noise voltage in the
AMI Transmitter it is mandatory to connect a snubber circuit in parallel to the load. A snubber is not necessary if an AMI relaybox is
used.
Resistive load Resistive loads (max. 1A) and control signals for PLC, impulse
pumps and so on can be connected without further measures
Actuators Actuators, like motor valves, are using both relays: One relay con-
tact is used for opening, the other for closing the valve, i.e. with the
2 relay contacts available, only one motor valve can be controlled.
Motors with loads bigger than 0.1 A must be controlled via external
power relays or an AMI relay box.

6.4. Conductivity-Resistivity QC-Kit Test Plug
The QC-Kit test plug fulfills the requirements of the United States
Pharmacopeia (USP).
6.4.1 Introduction
The test plug consists of 2 high precision resistors for conductivity
and temperature.
The plug has a resistor of
5000 (+/- 1%) for temperature
181800 (+/- 1%) for conductivity.
NOTICE: Keep test kit absolutely dry!
Several variables enter into the calculation of specific conductivity.
Values like the cell constant, temperature compensation algorithm,
cable length and temperature correction of the sensor are stored in
the memory of the conductivity instrument.
Test mode For a quick and easy test, the AMI Rescon transmitter has the test
mode <Transmitter check> that enables testing without changing
any of these values. When leaving the test mode, all parameters
will be set back to their original value.

As control
output
Signal outputs can be used for driving control units. We distinguish
different kinds of controls:
P-controller: The controller action is proportional to the devia-
tion from the setpoint. The controller is characterized by the
P-Band. In the steady-state, the setpoint will never be
reached. The deviation is called steady-state error.
Parameters: setpoint, P-Band
PI-controller: The combination of a P-controller with an
I-controller will minimize the steady-state error. If the reset
time is set to zero, the I-controller is switched off.
Parameters: setpoint, P-Band, reset time.
PD-controller: The combination of a P-controller with a
D-controller will minimize the response time to a fast change
of the process value. If the derivative time is set to zero, the
D-controller is switched off.
Parameters: setpoint, P-Band, derivative time.
PID-controller: The combination of a P-, an I - and a D-con-
troller allows a proper control of the process.
Parameters: setpoint, P-Band, reset time, derivative time.
Ziegler-Nichols method for the optimization of a PID controller:
Parameters: Setpoint, P-Band, Reset time, Derivative time
The point of intersection of the tangent with the respective axis will
result in the parameters a and L.
Consult the manual of the control unit for connecting and programming details. Choose control upwards or downwards.

5.2.1.43.23 P-Band: 0.00 –200 M or 0.000– 2000 S
5.2.1.43.3 Reset time: The reset time is the time till the step response of a sin-
gle I-controller will reach the same value as it will be suddenly
reached by a P-controller.
Range: 0– 9’000 sec
5.2.1.43.4 Derivative time: The derivative time is the time till the ramp re-
sponse of a single P-controller will reach the same value as it will
be suddenly reached by a D-controller.
Range: 0– 9’000 sec
5.2.1.43.5 Control timeout: If a controller action (dosing intensity) is constantly
over 90% during a defined period of time and the process value
does not come closer to the setpoint, the dosing process will be
stopped for safety reasons.

5.3.2 and 5.3.3 Relay 1 and 2: The contacts can be set as normally open or normally closed with a jumper. See Relay Contacts 1 and 2, p. 28. The
function of relay contacts 1 or 2 are defined by the user.
NOTICE: The navigation in the menu <Relay 1> and <Relay 2>
is identical. For reason of simplicity only the menu numbers of
Relay 1 are used in the following.
1 First select the functions as:
- Limit upper/ lower
- Control upwards/ downwards
- Timer
- Fieldbus
2 Then enter the necessary data depending on the selected func-
tion.
When the relays are used as upper or lower limit switches, program
the following:
5.3.2.20 Parameter: select a process value
5.3.2.300 Setpoint: If the measured value rises above respectively falls below
the set-point, the relay is activated.
5.3.2.400 Hysteresis: within the hysteresis range, the relay does not switch.
This prevents damage of relay contacts when the measured value
fluctuates around the alarm value.
