Safety Instructions
Modifications Modifications and instrument upgrades shall only be carried out by
an authorized Service Technician. SWAN will not accept responsi-
bility for any claim resulting from unauthorized modification or alter-
ation.
WARNING
Electrical Shock Hazard
If proper operation is no longer possible, the instrument must be
disconnected from all power lines, and measures must be taken
to prevent inadvertent operation.
To prevent from electrical shock, always make sure that the
ground wire is connected.
Service shall be performed by authorized personnel only.
Whenever electronic service is required, disconnect instru-
ment power and power of devices connected to.
– relay 1,
– relay 2,
– alarm relay
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).
Communica-
tion interface
(optional)
RS232 for logger download with HyperTerminal
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].
