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 CO2concentration 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 (acoustic 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 necessary for
the Ethernet interface 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

12
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.

13
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 TRHD-102…, TRHD-103…, Pt1000
probes and for external CO2probe. 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 TRHD-102…, TRHD-103… or Pt1000
probes. Conventional 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 CO2probe 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 ATM-AC02) - 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.
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
present (it does not work when the Multilogger is powered from
batteries).
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 rechargeable!
Charging batteries:
a) batteries can be charged if an external power source is
connected
