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 A201N-CC is a 2-wire device for two-channel measurement

of electrical conductivity and temperature in liquids. The device has

been designed for measurements before and after cation exchangers

using commercial analog 2-electrode sensors. Dierent parameters

can be calculated from the two conductivity values, e.g. dierence,

ratio, rejection, but also the pH value of feed water.

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 80.

Safety

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.

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.

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 12

• pipe mounting (Ø 40 … 60 mm, 30 … 45 mm)

see page 13

• panel mounting (cutout 138 mm x 138 mm acc. to DIN43700)

see page 14

Protective Hood (Accessory)

The protective hood, which is available as accessory, provides ad-

ditional protection against direct weather exposure and mechanical

damage; see page 13.

Connection of Sensors, Cable Glands

For connecting the cables, the enclosure provides

• 3 knockouts for M20x1.5 cable glands

• 2 knockouts for ½” conduit

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 25).

Color-Coded User Interface

The colored display backlighting indicates dierent operating states

(e.g., alarm: red, HOLD mode: orange; see page 26). The display

backlighting can be switched o; see page 64.

Introduction

Diagnostic Functions

“Sensocheck” automatically monitors sensor and cables; and the

“Sensoface“ function clearly indicates the sensor condition; see

page88.

Data Logger

The internal logbook (TAN SW-A002) can handle up to 100 entries –

upto 200 with AuditTrail (TAN SW-A003); see page 72.

Password Protection

Password protection (passcodes) for granting access rights during

operation can be congured; see page 76.

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 44.

Control Inputs (TAN SW-A005)

The oating, digital control input “HOLD“ allows remote controlled

switching to HOLD mode. The “CONTROL“ input allows evaluation of

external monitoring equipment, such as a ow monitoring system.

For that purpose, you can also monitor the current input for keeping a

desired value.

Signal Outputs

The device provides two current outputs (for transmission of

measured value and temperature, for example). The output curve is

adjustable (linear or bilinear), see page 48.

Options

Additional functions can be enabled by entering a TAN (p. 76).
