Introduction
Intended Use
Stratos Pro A4... MSPH/MSOXY is a two-channel process unit for mea-
suring pH and dissolved oxygen and temperature using 2 Memosens
sensors. It is used for biotechnology applications, in the pharma-
ceutical industry, as well as in the eld of industry, environment,
food processing and sewage 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.
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 sensor monitoring 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).
Password protection for granting access rights during operation can
be congured.
The oating, digital control input “HOLD“ allows remote controlled
switching to HOLD mode.
The “CONTROL“ input allows evaluation of external monitoring equip-
ment, such as a ow monitoring system.
For that purpose, you can also monitor the current input (optional) for
keeping a desired value.
The internal PID process controller can be congured as pulse length
or pulse frequency controller.
The device provides two current outputs (for transmitting the two
values measured for pH and oxygen, for example) and four oating
relay contacts. A time-controlled cleaning function can be congured.
Current is provided through a universal power supply
24...230VAC/DC, AC: 45 ... 65 Hz.

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, Certicates)
CAUTION!
Please 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 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.
Terminals:
Screw terminal, suitable for single wires / exible leads up to 2.5 mm2
(AWG 14).
Recommended torque for the terminal screws: 0.5 ... 0.6 Nm.

Memosens Cable CA/MS-...
Intended Use
Connecting cable for contactless inductive digital transmission of
measured signals (Memosens®).
The connecting cable consists of an inductive connector for digital
Memosens® sensors (bayonet lock). It allows connecting the ferrule-
terminated wires from the sensor loop of the transmitter. Contactless
inductive digital transmission of signals and energy eliminates the
inuence of humidity, electromagnetic elds and corrosion.
