Safety
Always Read and Observe the Safety Instructions!
The device is constructed in accordance with the latest technology
and generally accepted safety rules and regulations.
Under certain circumstances, however, usage may pose risks to users
or cause damage to the device.
Commissioning must be carried out by specialist personnel authorized
by the operating company. If safe operation is not possible, the device
must not be switched on or, if it is already on, must be switched o
properly and secured against unintended operation.
Reasons to assume safe operation is not possible:
• the device shows visible damage
• failure to perform the intended function
• prolonged storage at temperature of below ‑30°C/‑22°F or above
70°C/158°F
• severe transport stresses
Before recommissioning the device, a professional routine test must
be performed. This test should be carried out by the manufacturer at
its factory.
Intended Use
Stratos Pro A201COND is a 2‑wire device for measurement of elec‑
trical conductivity and temperature in liquids. Fields of application
are: biotechnology, chemical industry, environment, food processing,
water/wastewater treatment.
Stratos Pro A201X and the separately approved Ex sensor may be
operated in Zone 0 / Division 1.
Stratos Pro A201B and the separately approved Ex sensor may be
operated in Zone 2.
The dened rated operating conditions must be observed when using
this product. They can be found in the Specications chapter of this
User Manual; see page 113.

8
Function Check Mode (HOLD Function)
After activating conguration, calibration, or service, StratosPro enters
function check mode (HOLD).
The current outputs respond in accordance with the conguration.
Operations must not be carried out while StratosPro is in function
check(HOLD) mode, as the system may behave unexpectedly and put
users at risk.
Control Drawings
If installing in hazardous locations, observe the information provided
on the included Control Drawings.
Devices Not Intended for Use in Hazardous Locations
Devices identied with an N in their product name must not be used
in hazardous locations.
Conguration
Replacing components may aect intrinsic safety. The modules are not
intended to be replaced on devices in the Stratos Pro A201 product
line.

Introduction
Housing and Mounting Options
• The sturdy molded enclosure is designed for IP66/IP67/ TYPE4X
Outdoor protection, is made of PBT glass ber reinforced PC, and
has the following dimensions: H148mm, W148mm, T117mm.
Knockouts in the housing enable
• wall mounting (with sealing plugs to seal the housing)
see page 14
• pipe mounting (Ø 40 … 60 mm, 30 … 45 mm)
see page 15
• panel mounting (cutout 138 mm x 138 mm acc. to DIN43700)
see page 16
Protective Hood (Accessory)
The protective hood, which is available as accessory, provides addi‑
tional protection against direct weather exposure and mechanical
damage; see page 15.
Connection of Sensors, Cable Glands
For connecting the cables, the enclosure provides
• 3 knockouts for M20x1.5 cable glands
• 2 knockouts for ½” conduit
For quasi‑stationary installations with Memosens sensors, we recom‑
mend using the M12 socket accessory (ZU0822) instead of a cable
gland – which allows simple replacement of the sensor cable without
opening the device.
Sensors
The device has been designed for 2‑ and 4‑electrode sensors, particu‑
larly for Model SE600, SE603, SE604, SE610, SE620, SE630 sensors.
(It can easily be retrotted for Memosens sensors.)

10
Display
Plain‑text messages on a large, backlit LC display enable intuitive op‑
eration. You can specify which values are to be displayed in standard
measuring mode (“Main Display,” see page 33).
Color-Coded User Interface
The colored display backlighting indicates dierent operating states
(e.g., alarm: red, HOLD mode: orange; see page 34). The display
backlighting can be switched o; see page 84.
Diagnostic Functions
“Sensocheck” automatically monitors sensor and cables; and the
“Sensoface“ function clearly indicates the sensor condition; see
page132.
Data Logger
The internal logbook (TAN SW‑A002) can handle up to 100 entries –
upto 200 with AuditTrail (TAN SW‑A003); see page 103.
Two Parameter Sets A, B
The device provides two parameter sets that can be switched manu‑
ally or via a control input for dierent process connections or dierent
process conditions.
For an overview of parameter sets (original for copy), see page 48.
Password Protection
Password protection (passcodes) for granting access rights during
operation can be congured; see page 107.
TC process medium: Selecting the compensation method
The following temperature compensation methods are provided:
linear (by entering a temperature coecient), natural waters (nLF),
ultrapure water with traces of NaCl, HCl, NH3, NaOH, see page 72.
