Introduction
Intended Use
Stratos Pro A2... MSCONDI is used for measurement of electrical
conductivity and temperature in liquids using electrodeless sensors.
Fields of application are: biotechnology, chemical industry, environ-
ment, food processing, water/waste-water treatment.
The sturdy molded enclosure can be xed into a control panel or
mounted on a wall or at a post. The protective hood, which is avail-
able as accessory, provides additional protection against direct
weather exposure and mechanical damage.
The device has been designed for application with electrodeless
sensors of the SE 670 series (Knick).
Plain-text messages in a large, backlit display allow intuitive opera-
tion. The colored display backlighting signals alarm messages (red) or
HOLD mode (orange).
The “Sensocheck“ automatic monitoring of sensor and cables and
the “Sensoface“ function for clear indication of the sensor condition
provide excellent diagnostics.
The internal logbook (TAN SW-A002) can handle up to 100 entries –
up to 200 with AuditTrail (TAN SW-A003).
The device provides two parameter sets which can be switched
manually or via a control input for dierent process adaptations or
dierent process conditions (e.g. beer and CIP).
Password protection for granting access rights during operation can
be congured.
Two oating, digital control inputs (“Hold“ and “Control“) are available
for external control.
The device provides two current outputs (for transmission of
measured value and temperature, for example).

Safety Information
Safety information –
Be sure to read and observe the following instructions!
The device has been manufactured using state of the art technology
and it complies with applicable safety regulations.
When operating the device, certain conditions may nevertheless lead
to danger for the operator or damage to the device.
See also separate document:
• “Safety Instructions“.
(EC Declaration of Conformity, Certicates)
CAUTION!
Please note:
Before commissioning it must be proved that the device may be
connected with other equipment.
Commissioning must only be performed by trained personnel autho-
rized by the operating company! Whenever it is likely that protection
has been impaired, the device shall be made inoperative and secured
against unintended operation.
The protection is likely to be impaired if, for example:
• the device shows visible damage
• the device fails to perform the intended measurements
• after prolonged storage at temperatures above 70°C
• after severe transport stresses
Before recommissioning the device, a professional routine test must
be performed. This test must be carried out at the manufacturer's
factory.

Cable Device
The SE 670 sensor is connected to the RS-485 interface of the device.
When the SE 670 sensor is selected in the Conguration menu, the
default values are taken as calibration data. They can then be modied
by calibration.
*)Stratos Pro A2... MSCONDI is intended for connecting a SE 670 sensor
via RS-485 interface. It does not provide a measuring module.

Measuring Mode
After the operating voltage has been connected and the sensor identi-
ed, the device automatically goes to “Measuring“ mode. To call the
measuring mode from another operating mode (e.g. Diagnostics,
Service): Hold meas key depressed (> 2 s).

In measuring mode the display indicates:
• Measured value and time (24/12 h AM/PM) as well as temperature
in °C or °F (formats selected during conguration)
By pressing the meas key in measuring mode you can view the
following displays (for approx. 60 sec):
• Measured value and selection of parameter set A/B
(if set to “Manual“)
• Measured value and tag (point of measurement designation –
entered during conguration)
• Time and date
Pressing the enter key shows the output currents. They are displayed
as long as enter is held depressed, then the measured-value display
will return after 3 sec.
The device must be congured for the respective measurement
task!
