4 Pt100 sensors
-200°C ... 600°C
3- or 4-wire
64,000 measured
values

ECOLOG-NET LP4 dataloggers are network-ready 4-channel dataloggers for recording temperature val-
ues between -200°C and 600°C using Pt100 sensors in 3- or 4-wire circuit. 64,000 measured values can
be recorded. The data are loaded to the PC via local network. The datalogger provides the highest level
of data security because an internal battery backup allows data recording even in the event of a power
outage or network disruption There are various alarm features provided by the local alarm contacts and
the network functions.

2. Instructions and safety guidelines
2.1 Network and USB connection
The ECOLOG-NET family of dataloggers is fitted with a 10/100 Base T network connection point. The dat-
alogger functions and network can be configured using this connection.
In addition, the datalogger is equipped with a USB connection. This connection can be used for datalogger
configuration and data download if no network connection is available; however, it is not possible to define
network parameters using this connection. In the event that both the network connection and USB con-
nection are in use, data cannot be transmitted via LAN connection.
LAN

3.1 Assign network address
USB

In order to obtain an optimal USB connection, the following operational sequence should be followed:
1. Connect the power supply to the datalogger and turn on the PC
2. Once both devices are ready for use, connect the USB cable
3. The Windows driver for the USB connection being used must be installed. If the appropriate driver is
missing, it can be installed using the elproLOG ANALYZE software CD.
4. elproLOG ANALYZE: Options - Com Port - RS232 & 57600 (Hotseries 4) and appropriate COM-port.
2.2 Temperature effect
- For the range of application12.2 Operating range.
- It can't be guaranteed that the loggers will function properly if the datalogger is exposed to tempera-
tures which exceed the specified threshold range. Experience has shown that the battery freezes at
approx. -50°C, that it is no longer possible to perform measurements, and that the timer tracking func-
tion can be temporarily interrupted. Once it has been returned to room temperature, the logger must
be reprogrammed before it can be used again.
- At temperatures below - 20°C, the display is not easily readable; however, longterm use is not
affected.
- For longterm use above 40°C, lithium battery passivation can lead to temporary reading problems
(self-discharge protection), which can be resolved with repeated utilization.
- At temperatures above 45°C self-discharging of the battery increases. At continuous operations
above 45° C the battery life time will be reduced by 1/3.
- Exposure to temperatures above 55°C can result in permanent discoloration of the display.
- There is danger of a gas explosion if the lithium battery is heated to temperatures exceeding 100°C.
2.3 Exceptional environmental conditions
Pay attention to the following when dataloggers are used under special environmental conditions:
- IR radiation (heat) and superheated steam can damage the surface coating of the casing
- There is a risk that the battery may explode if the logger is used under microwave radiation
Initial startup

BEFORE THE INITIAL START-UP THE DATALOGGER MUST BE AT ROOM TEMPERA-
TURE!

Instructions and safety guidelines
2.4 Precautionary measures for handling units containing lithium batteries
Lithium batteries

- Do not short-circuit and charge batteries: Explosion hazard
- Do not throw units which contain batteries into fire: Explosion hazard
- Do not subject batteries to mechanical stress and do not dismantle them as leaking battery fluid is
highly corrosive and lithium can generate severe heat or can ignite a fire if it comes into contact with
moisture.
- Do not heat battery operated units to temperatures exceeding 100°C: Explosion hazard
- Avoid excessive impact
- Follow the manufacturer specifications for storing batteries
- Return batteries to the supplier for correct waste disposal
2.5 Precautions in handling with power supply units
Power supply unit

Follow the safety and application instructions of the power supply unit.
2.6 Battery backup / lifetime
Battery lifetime

2.7 Logger display / Power-saving mode
Power-saving mode -
display

The datenlogger ECOLOG-NET has a power-save mode which switches off the display. As a result, mea-
surements are only made during the defined log interval.. Four small circles located in the display indicate
that the datalogger is functioning and recording correctly. The display is switched on and off using the
elproLOG ANALYZE software - Extended setup - Display mode / power save. 5.2 Extended setup
Power-saving mode -
automatic

If no external power supply is available, the datalogger automatically enters power-saving mode. To check
the status during Power-saving mode, use the keypad to temporarily switch on the display.
2.8 Overlaying graphical data
Data from multiple
dataloggers

elproLOG ANALYZE Function: Overlaying
This function allows graphs from multiple dataloggers to be ECOLOG-NET LP4displayed simultaneously.
To utilize this function, each datalogger must have the same recording interval. 5.1 Datalogger setup
approx. 3 months In the event of a power failure, the internal battery backup functions for approximately.
Battery low This indicator (1.2 Display) is activated when the battery capacity limit is reached.
Replace the battery at the next possible opportunity (11. Maintenance).

3. Configuring the datalogger
3.1 Assign network address
Digi Device Discov-
ery
Fixed IP

For datalogger identification within a network environment, a unique network address is assigned to each
datalogger. This address is made up of 3 pieces of information: IP address, subnet mask and default gate-
way. For the elproLOG ANALYZE and elproMONITOR programs, we recommend the use of a static IP
address.
In order to avoid network conflicts, the network administrator must assign the addresses! These 3 pieces
of information must be entered manually into each datalogger using the software Digi Device Discovery.
For additional installation information see the elproLOG ANALYZE operating instructions, SE3003E,
or the online help feature. For additional network information see ECOLOG-NET service instruction
IT6001A.
This manual can be found on the ELPRO homepage at www.elpro.com/Download/Data Sheets/ECO-
LOG-NET networkable datalogger.
3.1.1 Desktop installation
The relevant network address is assigned to the datalogger during this workstep. This work should be per-
formed at the place of use prior to final installation, e.g. in an office.
3.1.2 Documentation
Documentation for the implemented configurations. Log the network parameters on a status printout from

This program is used for the on-line measured value display. For a detailed description of the functions

The datalogger requires an external power supply for the operation of the LAN interface. After
connection to the power supply, it takes approximately 1 minute until the datalogger responds
via the network.
...make a note of the IP address on the datalogger type label. This is the simplest way to identify
the datalogger during installation!


The ECOLOG-NET LP4 datalogger has a feature for monitoring threshold values. Threshold values and
alarm parameters are defined in the "Setup of Alarm Parameters" window. Threshold values are only mon-
itored using sensors that are selected in the "Datalogger setup - sensors" window. 5.1 Datalogger


- The measured value must be outside the defined tolerance range, i.e. the measured value is higher
than the maximum allowable threshold value or lower than the minimum allowable threshold value.
- The threshold violation must exceed the defined alarm delay times.
- The threshold violation remains active until the measured value reaches the defined tolerance range
again.
No alarm conditions are:
- Cable break of the sensor cable
- Short circuit of the sensor cable
- Readings outside of the measuring range

This is a potential-free switch-over contact. The contact switches when an alarm is triggered or when
the external power supply fails.
- Semiconductor contact alarm 1
Only reacts when there is an alarm
This is a semiconductor switch - break contact to datalogger GND
- Semiconductor contact alarm 2
Only reacts when there is an alarm
This is a semiconductor switch - make contact to datalogger GND
- Internal Buzzer

The status of D1 and D2 is not recorded in the alarm protocol and has no influence on the alarm contacts.
They are first logged to memory on the datalogger at the end of the following recording interval in memory.

Alarm forwarding is used in combination with the elproMONITOR software. The status (alarm / no alarm)
of the contacts is checked during the update of the monitor data. Status changes between two updates
