1 Introduction
The “Kompmaster” composting control unit from EHS is designed to control and log
the composting process by means of connected temperature and oxygen measuring sen-
sors. Only measuring sensors authorized by EHS for operation with the composting con-
trol unit must be connected to the control unit.
An integrated and buffered memory records and stores the data relevant to the assess-
ment of the composting process, until they are read and saved, which can be done using
the “Kompmaster” software for PCs provided.
It is recommended that you download the data in regular intervals and that you generate
and archive backup copies of your data.
2 Description
The “Kompmaster” control unit is used to control the compost decomposition and to log
the temperature values and the oxygen content. The control unit is designed for both
stand-alone and networked operation with maximum 32 control units.
In stand-alone operation, the connection to the control PC is achieved by means of an
RS232 interface which allows the use of any standard computer.
In networked operation
,
the connection to the control PC is achieved by means of an
RS485 interface
,
which requires the use of corresponding interface converters.
With the PC software provided it is possible to monitor the composting process during
running operation, allowing control of the composting process at any time. With the
help of the PC software you can also configure the settings and carry out the setup of the
composting control units connected.
For a detailed description of the software, please see the manual provided. In stand-
alone operation, only the control unit connected to the PC at the time (which must be
reinitialized after connecting) is visible in the PC software, and its measured values are
displayed.
In networked operation, the current measured values of all connected and active control
units are displayed on the PC. The settings and the control unit setup required can also
be carried out directly for all active control units using the PC software.
Once they are initialized, both units work “stand-alone” without the PC. The PC is only
required for programming and to archive and evaluate the data.
