2.2 Function
Sebalog D-3 (in short: Log D-3) is a compact, robust and extremely versatile data
logger. The device can record the readings of various sensor types in user-defined
intervals. Depending on the configuration, up to 4 freely programmable channels can be
connected to sensors for data recording.
The logger also can provide an internal pressure sensor hoses can be connected to
directly. When using the internal pressure sensor, in addition to the standard pressure
measurement the recording of sudden pressure fluctuations (known as ‘pressure
surges’) is possible.
Using the ‘real-time measurement’ function or the ‘Step Test’ function, a measurement
can be carried out and observed ‘live’ on a computer.
The logger can be used for monitoring purposes, as it is able to trigger user-defined
alarm signals (e.g. signal lights, SMS or e-mail) if a threshold is exceeded or special
alarm equipment is triggered.

Technical description
Externes GIS oder
Recorded measuring data are stored in the loggers memory and can be retrieved via
short range radio. Loggers equipped with a GSM module can also send the data
regularely to an FTP server, from where they can be downloaded to any Internetcapable computer.
Programming of the device, as well as retrieving and evaluating the recorded measuring
data is performed by the help of the ‘SebaDataView-3’ PC software.
2.3 Communication
The SebaDataView-3 software is used on a PC/laptop to program the logger before the
measurement and to retrieve the collected data after the measurement.
Short range radio is used for communication between the devices. The computer must
have a radio interface. For that purpose the ‘Log RI’ / "Log RI+"or the ‘Reader-3’ from
SebaKMT can be connected.
Furthermore, if your logger is equipped with an internal GSM module, measurement
data uploads to an FTP server or configuration data downloads to the logger are
possible.
GSM / GPRS

Technical description
2.4 Power supply
The device is powered by two internal Lithium batteries.
Battery lifetime
Battery status
The effective lifetime of the batteries strongly depends on which functions are used and
how often they are used.
Using the following settings and under the following conditions a logger can be operated
for up to five years without changing the batteries.
Parameter Setting
Channel 1 Internal pressure sensor
Channel 2 External sensor; Input signal: Pulse
Channel 3 External sensor; Input signal: Pulse
Channel 4 External sensor; Input signal: Pulse
Log interval 15 min
Event Number
Data transfer via GSM Once a day (SMS / e-mail / FTP upload)
Pressure surge recording Once a day
Alarm events per day No
In order to obtain information about a logger's battery condition, you can call the
'program' input screen of the SDV-3 software. For that, select the relevant logger in the
directory tree and click on Program in the menu bar. The State segment, inter alia,
provides information about the battery (see page 40).
Empty batteries
External power supply
When the batteries get low, the logger switches itself off. Measurement data, logged up
to that point, remain safely in the loggers’ memory until the next programming.
Empty batteries cannot be recharged. They need to be replaced. The battery
replacement must be carried out by SebaKMT or an authorized service station, in order
to warrant the loggers’ protection against water and dust ingress.
In order to expand the operating time of the measuring system, the data logger can be
supplied by an external energy source.
The Logger is connected to this source using the VK 76 connection cable (see page 24).
• Supply voltage: 12 V
• Supply current: approx. 0.5 A (if the GSM function is not used)
approx. 1.5 A (when using the GSM function)
Peaks of 4 A can occur.
NOTE

Technical description
External rechargeable
battery pack
2.5 Memory
In order to expand the operating time of the measuring system, the data logger can be
connected to an external rechargeable battery pack which can be ordered from
SebaKMT.
The logger is connected to the external battery pack by means of the VK88 connection
cable. The 10-pole connector (red) of the cable has to be plugged in the DC ext.
socket of the logger. Then the 5-pole connector has to be plugged in one of the sockets
of the battery, no matter which one. From now on the logger is powered by the external
battery only, until the connection is cut or the capacitance of the external battery gets
low. In that case, the logger switches back to internal power supply.
Use the supplied mains adapter to recharge the external battery pack. Plug the round
5-pole connector in one of the sockets of the battery, no matter which one. Once the
battery is connected to the mains, it is charging. The charging process for a fully loaded
battery takes 12 to 13 hours. Overcharging of the battery cannot occur if the supplied
mains adapter is used.
The device has 4 MB internal memory. For example, if 4 sensors are connected and a
recording interval of 5 minutes is specified, this is sufficient for 5 years non-stop data
recording. As part of the programming process, the logger can be set to "ring memory
mode". As the memory fills up with data in this mode, the device keeps logging and the
respective oldest value is overwritten.

3.1 Preparations for mobile communication
If your data logger is equipped with an internal GSM modem for mobile radio
communication, alarm messages and status messages can be sent via e-mail or SMS.
Furthermore, collected data can be transferred to an FTP server. From there they can
be downloaded with any Internet-capable computer anywhere in the world.
UMTS / GPRS
FTP server
E-mail messages
3.2 Preparing the logger for GSM
For data transfer via mobile radio you have to close a suitable contract with a mobile
phone service provider, in order to get a SIM card enabled for data transfer via
UMTS / GPRS.
For measuring data uploads, free memory space on an FTP server is needed. You can
ask your administrator to set up an FTP server using the server infrastructure of your
company or you can rent a server from a commercial internet service provider.
You can also rent FTP space from SebaKMT. Please contact your SebaKMT distributor.
Under certain conditions the demo server run by SebaKMT can be used.
If you wish to receive alarm messages or status messages via e-mail, an e-mail account
is needed from which the messages are to be sent. If the mail server of your company is
not capable for this task (e.g. due to a firewall), a webmail account from an internet
service provider (e.g. Yahoo or Google) can be used instead.
Under certain conditions the demo account run by SebaKMT can be used.
Please note that the mobile radio link function increases the loggers’ energy
demand, which has a strong negative influence on the battery life of the logger.
Insert SIM card
In order to prepare the logger for GSM connectivity, the SIM card you received from
your mobile operator has to be inserted and the GSM antenna must be connected.
Proceed as follows:
Step Description
1
Loosen the six screws and remove the cover of the device.
Result: Inside the housing you have access to the batteries and SIM card slot.
2
Insert the SIM card.
Please be careful not to damage any parts. Don't use any force.
NOTE
To remove the tray for the SIM card from its fastener, press the yellow spring
mechanism (see picture), e.g. by the help of a screwdriver or a pen. Remove the
tray and place the SIM card on it so it fits. Then push the tray back into the
bracket until it locks into place.
18
Commissioning the logger
Step Description
3
Attach the cover to the housing again.
The rubber seal inside the cover is not glued in and may possibly fall out.
Therefore, when re-assembling the device, it may be helpful not to put
the cover on the housing but to take both parts upside down and then put
the housing on the cover.
Connect GSM antenna
To ensure that the housing remains waterproof, please observe the following
points:
• The rubber seals and the housing and cover surfaces which touch each other
must be free of dirt.
• Be careful not to jam the housing parts against each other.
• Tighten the screws finger-tight (1 Nm). Do not overtighten!
The logger has no internal or external antenna. To enable the GSM connectivity the
delivered external GSM antenna must be connected to the device.
Connect the antenna to the GSM socket . Make sure that the guide on the plug fits in
the groove in the socket and that you feel the plug latch in.
19
Commissioning the logger
3.3 Switching the logger On/Off
The logger is switched on by the help of a magnetic switch.
Before switching the logger on, all connected devices have to be
disconnected (unplug connectors) because the internal relays of the logger
are initiated during the switch-on process. Thus, connected devices could be
NOTE
Move the supplied magnet in front of the contact area . After the magnet switch has
been activated, the I/O control lamp
blue after the logger has been started up. The device is now in energy saving mode.
Whenever a radio or GSM connection is established and whenever a data transfer takes
place, the logger automatically switches to data transfer mode.
In order to switch the logger off, the magnet must be held in front of the contact area
for a few seconds while the I/O control lamp
switches to red, the magnet has to be taken away from the contact area. Afterwards, the
logger switches off and the lamp goes out. Make sure to take the magnet away
immediately after the lamp switches to red. Otherwise, the logger reboots right after it

Switching the device off has no effect on the measurement data stored. The
measurement data remain in the logger’s memory up to the time at which the device
receives new configuration data.
After being switched off and on again, the logger’s latest configuration still is
stored and can be retrieved, but it is no longer valid. The logger does not resume
measuring.
Furthermore, after being switched off and on again, the logger’s system time is
no longer current.
Therefore, the logger needs to be programmed anew after every restart.
3.4 Programming the logger
Prior to its on-site installation, the logger must be properly configured using the supplied
SebaDataView-3 software. In doing so, the logger has to be provided with the channel
allocation, the alarm conditions and the wireless connection parameters among other
things.
Please refer to the according chapter in order to get a detailed description of how to
program the logger.

4 Connecting the logger and installing it on-site
4.1 Connecting sensors to the logger
Depending on its configuration, the following peripheral and measuring devices can be
connected to a logger:
• up to 4 sensors can be attached and the data can be logged (e.g. pressure, flow)
• up to 2 alarm-triggering devices (e.g. a light barrier) can be connected to the
switching inputs
• up to 2 devices (e.g. signal lamp, pump) can be connected to the switching outputs
and can be triggered in the case of an alarm
• one hose can be directly connected to the internal pressure sensors
Depending on the type of sensors / alarm devices connected, the appropriate parameter
values have to be provided to the logger using the SebaDataView-3 software. Please
refer to the according chapter in order to get a detailed description of the necessary
configuration steps (see page 42).
External sensors connected cannot be supplied by the data logger. They need a
separate power supply.
4.1.1 Fixed channel allocations
2-channel loggers
4-channel loggers
The internal pressure sensor is always linked to measuring channel 1. The respective
channel is in use and must not be connected to an external sensor.
Due to the internal wiring of the logger, current loops can only be connected to the
channels 2 and 4.
Corresponding to these conventions, the following channel allocations apply for
2-channel loggers which are equipped with a pressure sensor:
Channel 1 Channel 2 Channel 3 Channel 4

The following channel allocations apply for 2-channel loggers without pressure sensor:
