Transportation Damages!
Please inspect the instrument immediately after receiving for potential
shipping damages.
For any claims to the transportation insurance or warranty repair, it is
absolutely required to notify transportation damages immediately after
receiving the instrument. In case of obvious damages of the outer
packaging, the carrier must give a receipt for this damage to make
demands for the insurance. In case of a delayed announcement the
insurance will not pay for damages and Chemtronic Waltemode GmbH will
not assume liability for these damages.

SAFETY INSTRUCTIONS
Pay attention to the following general safety instructions during use and operation of the system.
Ignoring these instructions or special warnings inside of this manual can damage the sensor, cause
inaccurate measurements, and possibly result in unsafe installations. Chemtronic Waltemode GmbH will
not take any responsibility for consequences arising from ignoring the safety instructions and warnings.
For all chemical liquids
The product you measure is may be toxic or otherwise harmful to human health. Observe appropriate
precautions when handling and disposing the liquid. Review the appropriate published material safety
data sheets regarding the safe handling and disposal of all reagents or standards.
Electrical installation
Qualified technical personnel must install the electrical installation of the system. This instrument
requires an input of 90-260VAC at 50-60 Hertz (unless otherwise specified). A 24VDC/AC power supply
is optional.
Hazardous area
DO NOT INSTALL the system in hazardous area without the optional Ex-proof equipment. Operation of
non Ex- proof systems in hazardous area will cause a high risk.
Using the system in hazardous areas (Ex Zone I / Ex Zone II) will
only be safe with the installation of the optional special Ex-proof
designs including all required certifications
Maintenance
Always disconnect the instrument from power during maintenance, replacement of components,
installation of additional components or any other operations at the open instrument. Only qualified
technical personnel must perform this work.
Operating the instrument with open enclosure
Only qualified technical personnel should operate the instrument when the enclosure is open. Take care
that no moisture enters the enclosure.
Some components inside the instrument are energized with
voltages, which can cause lethal shocks in case of contact. Be
careful during installation, handling and operation of the
instrument.
Improper installation / operation of the system
Warranty is void if the system is installed improperly, handled improperly, used outside of the
technical specifications (of the instrument), or damaged by gross negligence.

BEFORE INSTALLATION AND STARTUP
System Inspection
Check to ensure that all components of the instrument have arrived safely. Included should be: the Messenger Transmitter, the
Sensors and the cable sets and Manual.
The Messenger versions without display and with LCD include typically additional a Cd- Rom with Messenger Graph
Software and an Interface adapter Model USB-Nano.
If there is any damage to the equipment or if anything is missing please contact us immediately. Save the packing
material for future system storage or shippingI
Please read the additional safety instructions before installation and start-up!
General Installation guidelines
1. Transmitter and Sensors are sensitive components, do not drop and handle with care.
2. Follow the wiring diagram (pay attention to sensors manual) during installation of the system.
3. The process temperature and pressure cannot exceed the specification of the delivered Sensor.
4. Avoid air and gas bubbles inside the sensor, they cause disturbances. Nois
e and drift of the measurement would be the result (th
bubbles are not expected at a pressure upwards of 2 bar in aqueous solutions).
5. Please do not use the system in case of any visible mechanical damages!
6. The Messenger enclosure fits IP65 / Nema 4x protection class we recommend a dry / dust free area.
7. The ambient temperature for the transmitter must be in a range of -10°C to 50°C (use dry purge air above 40°C)
8. AC power consumption of the Messenger Transmitter is less than 50 Watts
9. Transmitter relay ratings for alarms and external devices are 2 A at 250V~ maximum
10. Do not operate with open enclosure. Exposed electronics will promote the risk of electrical shock and might cause damage to t
he
11. Do not alter cable length. The instrument was calibrated
with a specified cable length. Altering cable length can cause unstable s
and void instrument calibration.
12. Ship the instrument in the original packing material to avoid damage to the sensor or transmitter.
13. Mishandling of the system is not covered under warranty. Do not disconnect the interior wiring of the sensor.
14. Proper instrument grounding: The instrument must be grounded to avoid electrical shock hazards to person
nel, damage to the un
erroneous operation.
WARNING: MAKE SURE THE AC POWER MAINS ARE SWITCHED OFF OR OTHERWISE
DISCONNECTED BEFORE YOU BEGIN WIRING THE SYSTEM TO AVOID THE POSSIBILITY OF ELECTRICAL
SHOCK. IT IS A GOOD PRACTICE TO INSTALL A MAIN POWER CUTOFF SWITCH NEAR THE SYSTEM WITH
EXTERNAL MAIN FUSES.
THE SYSTEM REQUIRES AN AC-GROUND (EARTH GROUND) AND ALL SENSORS CONNECTED TO
THE TRANSMITTER MUST BE GROUNDED
Please note. The following points are important to avoid damages of the Sensors at
high temperature applications:
•Please connect purge air (cooling) before process insertion (dry, oil- & dust free instrument air )
•Leave air output open
•Do not interrupt the air cooling
• Remove the Sensor immediately from the process in case air purge is not guarantied!

General Information
Introduction
Monitek Messenger is a compact, highly efficient, and expandable system that is designed to interface
to a broad range of Monitek / Galvanic / Chemtronic sensors. It also has the capability to interface with
multiple and different sensors at the same time. It’s modular design approach enables several
applications to be customized for a variety of measurements, such as Turbidity, Suspended solids,
Color and % Concentration using optical in-line Sensors. The Messenger may be linked with Personal
Computer, Laptop or Netbook operating Windows XP / Vista / 7 or a Panel PC (also called a TPC), the
GUI (Graphical User Interface) offers completely menu-driven screens that are easy to understand and
also has online help. The GUI interface is designed to allow three access levels (Operator, Technician
and Factory) to prevent an unskilled operator from changing any critical parameter in the setup of the
transmitter. The interface is intuitive with no need for programming codes or program numbers. The
system also includes some self-check operations as well as the ability to access the basic
measurement values without the use of a multi-meter or even physically accessing the electronics. The
system includes the ability to perform field calibrations while the instrument is installed in the process
and is operating. It comes factory pre-configured to your application. For most accurate setup we
recommend that the user calibrate on his process sample condition. Please refer to Process calibration
Icons used in this User’s Manual
Important notice!
Cautions indicate situations that could damage the Monitek Messenger or
sensor. Cautions are printed in mixed case characters in boldface font
