General instructions:
Mount and put into service/start-up the
KEMPER KTS-ComLog module only after
reading these mounting and operating
instructions. They inform you in detail about
the mounting, commissioning, operating
principles and operation of the ComLog
module. Keep the mounting and operating
instructions with the unit or file with other
technical documentation in the system
documentation.
Operating principle
The ComLog module in combination with
one or more KEMPER KTS-ThermoBox(es)
serves as the interface to upstream
building automation systems.
For that purpose, the ComLog module is
linked with the bus cable of the KTS
controller units.
An additional ComLog module function is
logging the system data and the actual
values. The ComLog module has an SD
card slot to accomplish that.

are
taken
into
consideration.
Application range
The ComLog module is intended solely for use
in
combination
with
KEMPER

Mounting and installation
4.1 General
The device is electrically wired.
4.2 Preparation
First check the supplied materials for their
completeness.
4.3 Mounting
Look for a suitable mounting position and
fasten the housing at the intended
installation location.
Subsequently connect the controllers of
the KTS-ThermoBox(es) to each other
via bus cable and to the ComLog module
as illustrated in the following figure. To
do that, you need to remove the upper
part of the housing.

4.5 Mains connection
Have a skilled tradesmen make the
connection
to
the
mains
grid
(~230V / 50Hz) in accordance with the
relevant local power utility and VDE
directives. (It must be possible to cutoff the 230V mains feed line through
an emergency switch outside of the
heating plant room (only applicable to
plants > 50kW!)

Warning:
Only authorised specialists
are permitted to connect the
ComLog module. Danger of
death if the controller to the
230V mains feed line is
connected incorrectly.

Operation
4.7.1 Data storage of measured values
To enable the ComLog module to save all
measured values from the connected KTS
components, first a log file in the DAT
format must be created on the SD card.
The log file will be configured by the
Kemper
service
technician
during
commissioning and then transferred to
the
SD
card.
Based
on
the
correspondingly configured file, the
ComLog module creates a CSV file for
every day with the saved measurements
in the selected storage interval.
The CSV files can be copied and opened
and processed, for instance with Excel.
After copying, the CSV files have to be
deleted on the SD card.
To read the data from the ComLog module,
remove the upper part of the housing and
take out the memory card.

Note:
Save excel files and
delete files from SD card
But ATTENTION:
The correspondingly configured log file in the DAT
format must remain on the
SD card; otherwise the data
will not be saved.
4.7.2 Transfer
SD card
DAT
file
and
check
Take SD card from ComLog module
Copy DAT file from computer to SD card
Check internal recording
(Recommendation KEMPER: 10 sec.)
Insert SD card into ComLog module
Check whether SD card’s recording
Take SD card from ComLog module
(after approx. 10 minutes)
Read-out SD card with computer
Attention:
Don’t use other cards!.
Check temperature records
Check flow rate records

Configuring the log file:
The configuration of the log file is explained
below using the example of a KTSThermoBox as 2x cascade:
Open the log file with the name DAT in
MS-EXCEL.
In Cell A1, state the intervals in which
the values will be saved. In this
example, a storage rate of one second
is stipulated. If you want to save every
10 seconds, for instance, replace the 1
with a 10.
As delivered:
Time interval changed to 10 seconds:
In the column under ModBus ID, select
the corresponding ThermoBox from
which to read out the data.
Modbus ID 1 activates the master unit,
and
with ModBus ID 2, the slave unit is
activated.
With this configuration, all temperature
values and volume flows of both cascade
units are saved. Additional values can also
be saved, or, if they are not necessary, they
can be deleted.
The data points, register addresses and the
related settings can be taken from the KTS
ModBus data-point list.

Maintenance and repair
The measurements should be downloaded
from the SD card in regularly scheduled
intervals, but at a minimum interval of 3
months.
