You don't have to read the book from front to back.
Take a look at the Table of Contents or the Index to nd the function
you are interested in. Each topic is explained on a double-page spread
with step-by-step instructions on how to congure the desired func-
tion. Clearly legible page numbers and headlines help you to quickly
nd the information:

Autoclaving Counter
After reaching a specied limit value the autoclaving counter gen-
erates a Sensoface message. As soon as the counter has reached
the specied value, Sensoface is getting“sad”. Pressing the info key
shows the text “AUTOCLAVE CYCLES OVERRUN” which reminds you
that the maximum number of autoclaving cycles has been reached.
After each autoclaving process, you must manually increment the
autoclaving counter in the SENSOR service menu on the transmitter.
The transmitter displays“INCREMENT AUTOCLAVE CYCLE”as conr-
mation. You can congure the current outputs so that a Sensoface
message generates a 22-mA error signal, see page 63.

Introduction
Intended Use
Stratos Pro A401B PH is used for pH/mV, ORP and temperature
measurement in industry, environment, food processing and sewage
treatment.
Enclosure and mounting possibilities
• The sturdy molded enclosure is rated IP 67/NEMA 4X for outdoor
use. It is made of glass-reinforced PBT / PC and measures
148 mm x 148 mm x 117 mm (H x W x D).
It is provided with knockouts to allow:
• wall mounting (with sealing plugs to seal the enclosure),
see page 16
• post/pipe mounting (Ø 40 … 60 mm, 30 … 45 mm)
see page 17
• panel mounting (138 mm x 138 mm cutout to DIN 43700),
see page 18
Weather protector (accessory)
The weather protector, which is available as accessory, provides
additional protection against direct weather exposure and
mechanical damage, see page 17.
Connection of sensors, cable glands
For connecting the cables, the enclosure provides
• 3 knockouts for cable glands M20x1.5
• 2 knockouts for NPT 1/2” or rigid metallic conduit
For quasi-stationary installations with Memosens sensors, we
recommend using the M12 device socket (accessory ZU 0822) instead
of a cable gland – it allows simple replacement of the sensor cable
without opening the device.
Sensors
The device has been designed for application with commercially
available sensors with a nominal zero point at pH 7, ISFET sensors or
digital sensors. (It can be easily retrotted for Memosens sensors.)

8
Display
Plain-text messages in a large, backlit LC display allow intuitive
operation. You can specify which values are to be displayed in
standard measuring mode (“Main Display”, see page 38).
Color-coded user interface
The colored display backlighting signals dierent operating states
(e.g. alarm: red, HOLD mode: orange, see page 39).
Diagnostics functions
“Sensocheck“ automatically monitors the glass and reference
electrodes; and the “Sensoface“ function clearly indicates the sensor
condition, see page 137.
Data logger
The internal logbook (TAN SW-A002) can handle up to 100 entries –
up to 200 with AuditTrail (TAN SW-A003), see page 140.
2 parameter sets A, B
The device provides two parameter sets which can be switched manu-
ally or via a control input for dierent process adaptations or dierent
process conditions.
For overview of parameter sets (table for copy), see page 56.
Password protection
Password protection (passcodes) for granting access rights during
operation can be congured, see page 146.
Automatic calibration with Calimatic
You can choose from the most commonly used buer solutions,
see page 158.
An individual buer set can also be entered, see page 168.
Introduction

I input
The analog (0) 4 ... 20 mA current input can
be used for external temperature compen-
sation (TAN required).
See page 88.
Control inputs
HOLD
(floating digital control input)
The HOLD input can be used for external
activation of the HOLD mode, see page 44.

CONTROL
(floating digital control input)
The CONTROL input can be used either for
parameter set selection (A/B) or for flow
monitoring, see page 90.
The “Wash” contact can be used for
indicating the active parameter set
(see next page).
Power supply
Current is provided through a universal power supply
24...230VAC/DC, AC: 45 ... 65 Hz.
Options
Additional functions can be activated by entering a TAN (page 146).

10
Introduction
Current outputs
The floating current outputs (0)4...20mA
are used for transmitting measured values.
An output filter can be programmed, the
fault current value can be specified.
See page 76.
Relay contacts
2 relay contacts for limit values. Adjustable
for the selected process variable:
hysteresis, switching behavior (MIN/MAX
limit), contact type (N/O, N/C) and delay
(page98).
Wash (cleaning function)
This contact can be used for controlling a
rinsing probe or for indicating the active
parameter set (page112).
Signal outputs
The device provides two current outputs (for transmission of
measured value and temperature, for example).
Relay contacts
Four oating relay contacts are available.

Safety Information
Be sure to read and observe the following safety 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 “Safety Instructions“ document.
CAUTION!
Note:
Before commissioning you must prove 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 below –30 °C or 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.

13
Safety Information
Application in hazardous locations:
Stratos A401B is approved for operation in hazardous locations.
Observe all applicable local codes and standards for the installation of
electrical equipment in hazardous locations.
For orientation, please refer to NFPA 70 (NEC), ANSI/ISA-RP12.06.01.
• When installing the device in a hazardous location, observe the
specications of the Control Drawing (download: www.knick.de).
• Before commissioning, you must provide proof that the device may
be connected with other equipment, such as a supply unit includ-
ing cables and wires.
• In hazardous locations the device shall only be cleaned with a
damp cloth to prevent electrostatic charging.
• Devices which have already been used shall be subjected to a pro-
fessional routine test before they may be operated in another zone
or another type of protection.

Installation
Safety Precautions for Installation
• Installation of the device must be carried out by trained experts in
accordance with this user 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 80 ... 230 V AC or 24 ... 60 V DC!
• A signal current supplied to the current input must be galvanically
isolated. If not, connect an isolator module.
• All parameters must be set by a system administrator prior to com-
missioning!
• The electrical installation shall conform to the national regulations
for electrical installations and/or other applicable national or local
codes or regulations.
• The power supply shall be disconnectable from the device by a
two-pole circuit breaker.
• Switch and circuit breaker shall be located in close proximity to the
equipment and be easily accessible by the OPERATOR. They shall be
marked as disconnect switch for the device.
• Be sure to disconnect the mains supply and any relay contacts
which are connected to separate current sources before starting
maintenance operations.
Terminals:
Screw terminals, suitable for single or stranded wires up to 2.5 mm2
(AWG 14).
Recommended torque for the terminal screws: 0.5 ... 0.6 Nm.
