1. General description
The logger EASYLOG 80CL is designed for long term monitoring of climate data. Not only
relative humidity, temperature and air pressure can be displayed, but also wet-bulb tem-
perature, dew-point temperature, enthalpy and the moisture content of the air.
The combination of low power consumption with high battery capacity ensure a long re-
cording 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.
2. Required accessory
The EASYLOG 80CL 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)
or
- USB <> EASYBus (i.e. EBW 3)
Connecting cable: level converter to EASYLOG
GSOFT 40K (version >7.14):
Windows software to start the logger and read out the logger-data
EASYBus-Configurator (version >2.0) or EBxKonfig (version >3.9):
for the configuration of the extended settings

3. Safety advice
This device has been designed, assembled and tested in accordance with the safety regu-
lations for electronic measuring device. However, its trouble-free operation and reliability
cannot be guaranteed unless the standard safety measures and special safety advices
regarding the device will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the
device is not subjected to any other climatic conditions than those stated under
”Specification”.
To protect the battery, the maximum permissible storage and transport
temperature of the device is 70 °C
2. Standard regulations for operation and safety for electrical, light and heavy current
equipment have to be observed, with particular attention having to be paid to
national safety regulations.
3. When connecting the logger to other devices (e.g. PC) the interconnection has to
be designed most thoroughly as internal connections in third-party devices (e.g.
connection GND with protective earth) may lead to undesired voltage potentials.
4. If there is any risk whatsoever involved in running it, the device has to be switched
off immediately and to be marked accordingly to avoid re-starting.
Operator safety may be at risk if:
•there is visible damage done to the device
•the device is not working as specified
•the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair and maintenance.
5. Warning:
Do not use these product as safety or emergency stop devices, or in any other
application where failure of the product could result in personal injury or material
damage.
Failure to comply with these instructions could result in death or serious
injury and material damage.
4. 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 EASYLOG 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.

7.3 Operating possibilities via software GSOFT 40K
You can easily operate the logger via the software GSOFT 40K (> V7.14). This software
provides a variety of functions to operate the logger. For example:
•start and stop the logger
•read out the logger data; illustrate them graphically and save them
•adjust the alarm boundaries and alarm delay *1
•activate the sea-level correction and enter the actual sea level *1
Description: The measured barometric air pressure can be converted to the air
pressure at sea level if the actual height above sea level is entered.
•activate the function: “logger stop via buttons disabled“
*1Please note: The alarm settings and the sea-level correction can be only
changed if the logger is stopped (= logger without logger data).
7.4 Operating possibilities via software EBxKonfig or EASYBus-
Configurator
The software EBxKonfig (> V3.9) or EASYBus-Configurator (> V2.0) is needed to
change the configuration settings.
With that software the following adjustment are additionally possible.
•Selection of the unit of the calculated variables*2
•Offset and slope adjustment for each measured variable *2
•Activation of the function: “do not stop active logger”
*2Please note: This can be only changed if the logger is stopped (=logger without
logger data)
8. Battery life time and recording period
Measuring cycle: 4 sec 3 min 15 min 5 h
Recording period: 11.5 days 521 days 7.1 years 142 years
Battery life time: -- -- ca. 5 years --
Please note: Short measuring cycles seriously reduce the battery life time!
In this case you should consider not unplugging the EASYBus-
interface.
Then the logger is supplied via the interface.
The internal battery is spared.

9. Operating displays
The EASYLOG provides two LCD-displays: 7 mm (main display) and
5.8 mm (secondary display).
9.1 Measured value display
The LCD mainly displays the measured values:
a)
°C
%
AL Logg
b)
hPa
°C
SL Logg
MEASURED VALUE DISPLAY
Alternating display of the following measuring channels:
a) main display: humidity [ % ]
sec. display: temperature [ °C ]
b) main display: selected calculated variable with the
corresponding unit arrow (here: Td)
sec. display: air pressure [ hPa ]
The particular measuring channels are displayed for about 4 sec.
and then are automatically switched to the next ones.
•The arrow “Logg“ signals that the logger is recording.
•The arrow “AL“ signals an alarm state at minimum one channel.
•The arrow “SL“ signals an active sea-level correction .
9.2 Logger status messages
At stand-alone-operation (= no EASYBus connected) logger status messages are dis-
played.
STOP:
The EASYLOG recording has been ›stopped‹.
The logger memory is empty.
Note: At this state the power consumption is at its
minimum.
HOLD:
The EASYLOG recording has been ›halted‹. No data is stored,
but the logger memory contains data.
The number of the saved recording sets is shown at the
secondary display.
START DELAY:
The logger is activated, but no data is recorded yet.
As soon as the start delay is run out the logger begins with the
recording according to the programmed starting condition.
START ALARM:
The logger is activated, but no data is recorded yet.
The logger begins with the recording as soon as the measured
values are within the selected min- and max-alarm boundaries.

BATTERY:
•display of the BAT-arrow left hand down:
The EASYLOG battery is almost spent and needs to be replaced.
The data recording is still active.
• permanent display BAT:
The battery is spent and the recording has been automatically
stopped (even if at EASYBus-operation).
It is still partly possible to read the measured values and to
read-out the saved logger data.
=> Please return the logger to the manufacturer.
ERROR 7:
The EASYLOG has detected a system error.
• remedy: Reset the error via GSOFT 40K.
If the error message is displayed furthermore please
send the logger to the manufacturer for repair.
9.4 Alarm and error messages
The following messages correspond to a particular measuring channel and are dis-
played accordingly.
ALARM LOW:
The measured value is below the selected min-alarm limit.
This and the current value is displayed alternately.
ALARM HIGH:
The measured value is above the selected max-alarm limit.
This and the current value is displayed alternately.
ERROR 1:
The measuring range of this channel is exceeded.
ERROR 2:
The measuring range of this channel is under-run.
ERROR 9:
The sensor for this channel provides invalid values.
ERROR 11:
The variable could not be calculated, because the measuring
range has been exceeded or a measured value, that is needed for
the calculation, is not available or faulty.
Note: A description of the possible reasons for that error messages is in
chapter 12 (FAQ).
