WARNING
For safe instrument installation and operation you must read
and understand the instructions in this manual.
WARNING
Only SWAN trained and authorized personnel shall perform the
tasks described in this document.
1.3. Restrictions for use
The AMU Rescon is designed for determination of specific conduc-
tivity or resistivity in high purity water.
To avoid clogging the flow cell, prevent sand, oil or solids, from en-
tering into the flow cell.
Sufficient sample flow is coercive for the correct function of the in-
strument. 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 resis-
tivity or specific conductivity in high purity water.
Measuring
Principle
The resistivity of high purity water is determined with a sensor con-
sisting 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 simultaneously 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 scal-
able, linear, bilinear, log) or as continuous control output (control
parameters programmable).
Current loop: 0/4–20 mA
Maximal burden: 510 Ω
Relays Two potential-free contacts programmable as limit switches for
measuring values, controllers or timer for system cleaning with au-
tomatic hold function.
Maximum load: 100 mA/50 V
Alarm Relay One potential free contact. Summary alarm indication for program-
mable alarm values and Instrument faults.
Available in two configurations:
Normally open*: Closed during normal operation, open in case of
error or power loss.
Normally closed: Open during normal operation, closed in case
of error or power loss
*Standard configuration. To order the version with normally closed
alarm relay, contact your dealer in advance.
Maximum load: 100 mA / 50 V

Product Description
Input One input for potential-free contact to freeze the measuring value
or to interrupt control in automated installations (hold function or re-
mote-off).

tion interface

RS485 with Fieldbus protocol Modbus or Profibus DP (optional)
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.
USP
Operating
Mode
The USP Operating Mode implemented in the firmware of the AMU
Rescon transmitter allows the measurement of pharmaceutical wa-
ter 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 ils set to <on>, the temperature com-
pensation function is disabled. The uncompensated measuring val-
ues 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.
Conductivity
QC-Kit Test
Plug
The implemented Transmitter Test together with Conductivity QC-
Kit Test Plug containing a traceable high precision resistor allows to
perform a verification of the 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].
2Screw on the union nut onto the body, do not tighten it.
3Push the stainless steel pipe through the union nut as far as it
reaches the stop of the body.
4Mark the union nut at 6 o’clock position.
5While 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.

The following instruction applies for all flow cells and 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 sub-
merged.
