2 Safety
2.1 Intended Application
The transmitter Mycom CLM 152 is a microprocessor-controlled measuring and control
instrument used to determine and evaluate specific conductivity. Since it has been
designed to permit extensive programming and the addition of optional plug-in modules, it
can be adapted to different process applications. If the version of the Mycom CLM 152
with intrinsically safe design is chosen, it can be operated in explosive atmospheres as
well.
2.2 General Safety Instructions
Warning!
Operating this instrument in any way other than described in these instructions may
compromise the safety and function of the measuring system.
The Mycom CLM 152 instrument has been designed and manufactured for safe operation
according to the state of the art in engineering and conforms to the relevant regulations
and US and EC directives (see Technical Data). However, if used improperly or other
than the intended purpose, it may be hazardous, e.g. due to improper connection.
Installation, electrical connection, start-up, operation and maintenance of the measuring
system must therefore be performed exclusively by trained specialist personnel properly
authorized by the system operator for such work. The specialist personnel must be
familiar with these operating instructions and must adhere to the instructions contained
therein.
2.3 Safety Functions
Access Code: Unauthorized access to the calibration and configuration
data of the transmitter is effectively prevented by access
codes.
Alarm Function: The failure contact is activated in case of system faults,
temperature sensor failure and serious defects.
The alarm contact is fail-safe by design, i.e., the alarm is
also actuated immediately in case of a power failure.
Data Integrity: The current configuration is maintained even after a power failure.
Electromagnetic compatibility: This instrument is protected against interference,
such as pulse-shaped transients, high frequency and
electrostatic discharges in accordance with the
current European standards.
This is, however, only the case for instruments
connected as outlined in these operating instructions.
