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 / 158 °F
• after severe transport stresses
Before recommissioning the device, a professional routine test in
accordance with EN 61010-1 must be performed. This test should be
carried out at the manufacturer’s factory.
CAUTION!
Before commissioning, make sure that the transmitter may be

Intended Use
The Stratos Eco 2405 CondI is used for measurement of electrical
conductivity and temperature in liquids using electrodeless (toroidal)
sensors. Fields of application are: biotechnology, chemical industry,
environment, 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 provides ad-
ditional protection against direct weather exposure and mechanical
damage.
The device has been designed for application with electrodeless
sensors, in particular for sensors of the SE 655/656/660 Series (Knick).
It provides two current outputs (for transmission of measured value
and temperature, for example), two contacts, and a universal power
supply 24...230VAC/DC, AC: 45 ... 65 Hz.

Installation Instructions
CAUTION!
• Installation of the Stratos must be carried out by trained experts in
accordance with this instruction manual and as per applicable local
and national codes.
• Be sure to observe the technical specications and input ratings
during installation.
• Be sure not to notch the conductor when stripping the insulation.
• Before connecting the device to the power supply, make sure that
its voltage lies within the range 20.5 ... 253 V AC/DC.
• All parameters must be set by a system administrator prior to
commissioning.
The terminals are suitable for single wires and exible leads up to
2.5mm2(AWG 14).

• Insert the special cable through
the cable entry into the terminal
compartment.
• Remove the already separated part
of the cable insulation (1).
• Turn the shielding mesh (2) over the
cable insulation (3).
• Then shift the crimp ring (4) over the
shielding mesh and tighten it using a
pince (5).

AC applications with inductive load
1 Load
2 RC combination, e.g. RIFA PMR 209
Typical RC combinations for 230 V AC:
Capacitor 0.1 µF / 630 V Resistor 100 ohms / 1 W
3 Contact
Protective Wiring of Relay Contacts
Relay contacts are subjected to electrical erosion. Especially with
inductive and capacitive loads, the service life of the contacts will be
reduced. For suppression of sparks and arcing, components such as RC
combinations, nonlinear resistors, series resistors and diodes should
be used.
