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.

AMI Rescon
Product Description
Input One input for potential-free contact to freeze the measuring value
or to interrupt control in automated installations. Programmable as
HOLD or OFF function.
Communica-
tion interface
(optional)
USB Interface for logger download.
Third signal output (can be used in parallel to the USB interface)
RS485 with Fieldbus protocol Modbus or Profibus DP
HART interface
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].

3.3. Connecting Sample Inlet and Outlet
3.3.1 Sample Inlet
Preparation For the sample inlet a stainless steel tube is connected to the Swa-
gelok fitting at the flow cell. Cut the tube to length and deburr it. The
tube must be straight and free from blemishes for approximately
1,5 x tube diameter from the end.
Lubrication with lubricating oil, MoS2, Teflon etc. is recommended
for the assembly and reassembly of bigger sized unions (thread,
compression cone).
Installation 1 Insert the compression ferrule [C] and the compression
cone [D] into the union nut [B].
2 Screw on the union nut onto the body, do not tighten it.
3 Push the stainless steel pipe through the union nut as far as it
reaches the stop of the body
4 Mark the union nut at 6 o’clock position.
5 While holding the fitting body steady, tighten the nut union 1¼
rotation using an open ended spanner.
3.3.2 Sample Outlet
FEP flexible tube 6 mm. Connect the tube to the serto elbow union
and Insert it into an atmospheric drain of sufficient capacity.
Max. tube length is 1.5 m. Do not connect longer tubes.

3.4. Install Sensor RCU
The following instruction applies for all, the flow cell and the pipe
flanges. To install the sensor RC U into a flow cell or a pipe flange
proceed as follows:
Install Sensor
into Flow Cell
Install Sensor
into a tube
Installation in a by-pass is recommended. Choose the installation
point carefully, to ensure the sensor is always filled with water, even
if sample flow is interrupted. To avoid the formation of air bubbles
inside the sensor make sure that the air vent holes are always submerged.

3.5. Connect the Resistivity Sensor Cable
WARNING
Electrical shock hazard!
Before opening the AMI Transmitter switch power off.
Use one of the cable glands to feed the sensor cable into the sensor housing.
1 Choose a suitable cable gland, see chapter Electrical Connec-
tions, p. 23.
2 Remove the plug [A] from the cable gland [B].
3 Open the AMI transmitter housing.
4 Feed the sensor cable through the cable gland [B] into the
transmitter housing.
5 Connect the cable to the terminals according to the connecting
diagram see Connection Diagram, p. 25.
6 Close the AMI transmitter housing.
7 Switch on power.
3.6. Connect the Flow Sensor Cable
If a flow cell with a flow sensor was ordered (QV-Flow) connect it to
the AMI Transmitter. Proceed according to chapter Connect the Re-
sistivity Sensor Cable, p. 22.
