Introduction
The Multilogger has been designed for measuring and recording physical
and electric quantities with an adjustable logging interval from 1 second to
24 hours. The device is equipped with 4 inputs (connectors) for external
probes or signals. Moreover, some versions also include an internal
atmospheric pressure and/or CO2 concentration sensor. The production line
consists of several models with various combinations of the input ranges of
the measured quantities. The Multilogger can be used either as stationary or
portable device.
The device allows for:
- Measuring and processing input quantities; the maximum number of
the measured and calculated quantities is 16. Some models can also
acquire data from binary inputs (up to 2 inputs). Models for measuring
barometric pressure allow sea level recalculation.
- Finding and storing minimal and maximal values for each measured
quantity (since their last manual reset).
- Acquiring autonomous time record of measured values, independent
of the mains supply. Recorded values can be stored as separate
samples in the recording time or as average/ minimal/maximal values
during the logging interval. Recording may be continuous, or only
during an alarm optionally.
- Creating alarm states and perform actions (audio and optical
signalization, alarm output signal, report messages via telephone dialer
and/or various Ethernet interface protocols, etc.).
- On-line monitoring of the measured values and states. Accessing
these values via the web.
- Collecting and processing data in the central database.
- Powering by batteries (NiMH accumulators or alkaline batteries).
- Powering by external power supply, which can be also used for
charging NiMH accumulators. External power supply is required for full
operation of the Ethernet interface. Some limited functions of this
interface may be available during battery operation.

Installation instruction
Location of Multilogger must match the operating conditions and not allowed
manipulations.
Working position of the device:
Multilogger placed on a horizontal, nonflammable surface (horizontal
working position is not suitable for devices with thermocouple inputs and for
devices with cable-less probes).
Multilogger fixed on the wall from nonflammable materials or in a low-
current switchboard using the holder - the working position is with input
connectors upwards.

Recommendations for mounting
Do not mount Multilogger near sources of interference (Multilogger
must not be mounted directly to power switchboard nor to its nearness.
Also do not mount data logger near power contactors, motors, frequency
converters and other sources of strong interference).
In cable routing follow rules of standards for installation of low current
distribution (EN 50174-2), especially it is necessary to pay attention to
avoid electromagnetic interference intrusion to the leads, transmitters,
transducers and sensors. Do not locate cabling near sources of
interference.
Do not use leads in parallel with power distribution network leads
IE-MLG-M1xxx-07 13
Do not use cables longer than 30 m generally; for RTD sensors is
recommended max. 15 m; cables must be installed only in interior areas.
Do not interconnect the inputs with other measuring systems.
Use shielded cables for the voltage and current inputs - connect the
shielding to the Multilogger but not to the end devices if these do not have
a special terminal for it. In this
case, shielding must not be
connected to external metal
parts of this device or to any
other device. Never use
shielding as a signal wire.
14 IE-MLG-M1xxx-07
Do not use common leads for several inputs.
It is recommended to earth larger systems with Multilogger at one
point - the GND terminal of the alarm output can be used for this purpose.
This grounding will work correctly if the system would not be grounded
currently at another point too. One-point grounded systems are more
resistant against electromagnetic disturbance.

Input connectors
The Multilogger does not have galvanically isolated inputs. For this reason,
only devices that are not connected to any other circuit may be connected to
the inputs of Multilogger. Simplified circuit diagram of inputs is shown in
Appendix 3.
MiniDIN connector _______________________________
It is used for connecting the DigiS/M…, DigiL/M…, Pt1000/M probes
and for external CO2 probe. Plug properly oriented probe connector to
the input of Multilogger. You can follow the optical key for correct
position. Make sure that the wires, including their shielding, are not
connected to any other conductive parts! Universal MiniDin connectors
are designed for DigiS/M…, DigiL/M… or Pt1000/M probes.
Conventional (custom) probes with a Pt1000 sensor can also be
connected, however with certain
limitations (see Appendix 4). The
input connector marked “CO2” is not
universal and it is designed for
external CO2 probe only.
Universal thermocouple connector ___________________
Plug properly oriented connector to the input of Multilogger. The
connector is mechanically coded using a wider pin. Use the white
uncompensated connector for measuring voltage. Make sure that the
wires are not connected to any other conductive parts! Electrical
coupling among thermocouples can cause large measurement errors
or instable values! To obtain correct measurement values, the
Multilogger has to be temperature-stabilized!

Alarm output
This output is accessible on terminals on the bottom side of the Multilogger.
Here are available these signals: OUT - open collector transistor, +5V power
supply from external power source and GND terminal (see also the diagram
in Appendix 2).
As the default, this output transistor is switched during selected alarms. It is
possible to set inverse behavior in the device's configuration (in this case
loss of external power supply acts as an alarm state). Activity of this output
can be canceled from the Multilogger keypad or remotely from a PC or web.
Remember to set a suitable alarms delay to prevent false activity of this
output.
It is possible to connect to this output:
External audio alarm (optional accessory MP026) - connect the +5 V
terminal with the central lead of the CINCH connector of the audio alarm
unit and the OUT terminal with the outer lead of CINCH connector (see
the picture).
ATTENTION - the External audio alarm unit will not work if the
Multilogger does not have an external power supply.
Telephone dialer (optional accessory MP002) - in case of alarm
telephone dialer dials specified telephone number and announces voice
message. Connect the dialer according to its operation manual.
External alarm with its own power supply - make the connection
according to the following picture. Be careful do not exceed the maximum
allowed output current from OUT terminal (see the part Technical
Parameters). Use an external relay for higher currents.

Power supply of Multilogger
The Multilogger is powered from three AA batteries and optionally also from
an external +5 V DC power supply, which can be also used for charging the
batteries. A simplified schematics of the internal supply circuits is showed in
Appendix 2.
External power supply _____________________________
External power supply can be connected to the Multilogger in
several ways:
a) to the power supply connector on the bottom of Multilogger
(for example, AC adapter included in basic accessories)
b) to the terminal block of the RS232 interface (+5 V and GND
terminals)
c) via USB cable connected to PC (it will work only if the USB
port of the PC has current sufficiency to power the
Multilogger)
No energy from the batteries is discharged if external source is
present.
The Ethernet interface works only if an external power source is
connected. Some limited functions of this interface may also be
available during battery operation.
ATTENTION - never connect voltage greater than 5.5 V to
the external power supply input - it could damage the
device.
Batteries _______________________________________
The new Multilogger is equipped with high-quality NiMH
rechargeable batteries; the device is preset to intelligent algorithm
to their continuous charging if external power is present.
ATTENTION - if you insert the non-rechargeable batteries
to the Multilogger, change the battery model to Alkaline in
the device configuration. Never charge batteries that are
not rechargeabled!
Charging batteries:
a) batteries can be charged if an external power source is
connected
22 IE-MLG-M1xxx-07
b) the charging process will start if the NiMH charging
accumulators are selected in the device configuration
c) when the Multilogger is turned off, the batteries cannot be
charged
d) the Multilogger allows for two battery charging modes -
high current fast charging mode and low current slow
charging mode
Slow low current charging mode is mainly used for stationary
installations. Batteries work as a backup source in case of
external power failure. Charging is automatically activated
after restoring of external power supply. During slow charging
device operates normally. Recharging of completely
discharged battery takes several days, however, in normal
operation, do not expect a completely discharged battery. The
charging process is indicated on the device display using the
corresponding symbol .
Fast high current charging mode is mainly used for portable
applications. Discharged batteries can be recharged within a
few hours. The charging procedure has to be activated by the
service personnel:
a) If the Multilogger is on, switch it off. Connect an external
power supply to the device.
b) Press down and hold (approximately 3 seconds) the red
On/Off key on the Multilogger until you see “NiMH charger”
on the device display. The charging process is started.
c) During fast charging Multilogger does not work in the
normal operating mode, does not take measurements and
does not communicate with the PC.
d) Once the charging process is completed, the Multilogger
displays the “Batteries charged” message and you can turn
it off.
e) The charging can be proceed within a temperature range
of 0 °C to +40 °C only. If the temperature is out of this
range, the charging process is automatically stopped.
IE-MLG-M1xxx-07 23
Battery replacement:
If you want to keep the correct time setting in your device,
do not let the battery discharge completely.
When replacing the battery, do it quickly. The timer circuit
runs without battery for max. 5 minutes if the device is
switched off.
a) Switch the Multilogger off.
b) Remove the battery cover, take out the old batteries and
insert new batteries (take care for correct polarity). Battery
polarity is shown on its holder.
c) Switch the Multilogger on and make sure the set time is
correct (device menu View settings - General settings).
d) If you change the battery chemistry (rechargeable <=> non-
rechargeable), you have to make this change in the device
configuration also.
Note: The Multilogger can operate with removed batteries
powered externally. This is not a standard use of the device
but it is possible. In this case, the full battery is displayed.
Interruption of power supply causes loss of time setting.
