2. Safety
2.1 Intended Use
The logger EB-Logg80CL is designed for long term monitoring of climate data. Not only rela-
tive humidity, temperature and air pressure can be displayed, but also wet-bulb temperature,
dew-point temperature, enthalpy and the moisture content of the air.
The combination of low power consumption with high battery capacity ensure a long record-
ing time.
The last 250.000 measuring values of each variable (that means 1.000.000 values all in all)
are stores in the memory. The LCD-display informs about 2 different variables at the same
time (i.e. temperature and humidity) or about the operating status of the logger.
Only technically qualified persons are permitted to carry out installation, commissioning,
operation and decommissioning. The qualified personnel must have carefully read and
understood the operating manual before beginning any work.
This device must not be used at potentially explosive areas, as safety or emergency stop
devices or in any other application where failure of the product could result in personal
injury or material damage.
This device must not be used at a patient for diagnostic or other medical purpose.
The liability and warranty of the manufacturer for damages and consequential damages
are voided with misuse, disregard of this operating manual, assignment of inadequately
qualified technical personnel and arbitrary modifications of the product.

3. Product description
3.1 Required accessory
The logger is configurated, started and read-out via the EASYBus-interface. Therefore the
following accessories are required:
Level converter
- RS232 <> EASYBus (i.e. EBW 1, EBW 64, EBW 240)
- USB <> EASYBus (i.e. EBW 3)
Connecting cable: level converter to EB-Logg
GSOFT 40K (version >7.14):
Windows software to start the logger and read out the logger-data
EASYBus-Configurator (version >2.0):
for the configuration of the extended settings
3.2 Notes on the logger’s delivery status
The delivered logger is in a “sleep mode”, that means nothing is displayed and the
power consumption is at its minimum. When there is a communication with the software
for the first time, the EB-Logg leaves the sleep mode and ›Stop‹ is displayed. Then the
device is ready for operation.
Note: That sleep mode (nothing is displayed) cannot be restored again.
“Stop“ or “Halt“ are similar to the sleep mode. Both of that operation
modes ensure minimum consumption.
Note: Logger start over keypad:
before logger start over keypad, logger time must be adjust with
GSOFT 40K.
