Introduction
Intended Use
Stratos Pro A2... COND is used for measurement of electrical
conductivity and temperature in liquids. 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, which is avail-
able as accessory, provides additional protection against direct
weather exposure and mechanical damage.
The device has been designed for 2- and 4-electrode sensors, particu-
larly for Models SE 600, SE 603, SE 604, SE 610, SE 620, SE 630 and for
Memosens sensors.
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).
Approvals for Measurement in Hazardous Locations:
Stratos Pro A201/A211N COND: General Safety.
Stratos Pro A201/A211X COND: Approved for operation in
hazardous locations according to IECEx / ATEX / FM / CSA.

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, FM, CSA, ATEX (if applicable)
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.

Safety Information
Information for Installation in Hazardous Locations
(Stratos Pro A201/A211X COND)
Be sure to observe the stipulations of EN 60079-10 / EN 60079-14•
or the corresponding local regulations during installation and
commissioning. See also separate“Safety Instructions“ document.
Approvals for application in hazardous locations
(Stratos Pro A201/A211X COND)
according to IECEx in Zone 0, 1, 20, 21•
according to ATEX in Zone 0, 1, 2, 20, 21•
according to• cCSAus in Class I Div 1, 2/ Zone 1
according to FM in Class I, Div 1, 2/ Zone 1•
When the device provides dierent types of protection, the operator
must specify the applied type of protection during installation.
To do so, use the checkboxes on the rating plate:
Terminals:
Screw terminal, suitable for single wires / exible leads up to 2.5mm2
(AWG 14). Recommended torque for the terminal screws: 0.5... 0.6Nm.
