PRODUCT DESCRIPTION
The dataloggers are designed for measuring and recording physical and electric
quantities with an adjustable logging interval from 1 second to 24 hours. The
measured values (instantaneous or the average, minimum and maximum values
detected during the recording interval) are stored in the internal non-
volatile memory. The data logging mode can be cyclic (when the data memory is
completely full, the oldest data are overwrite by the new ones), or non-cyclic
(the recording will stop once the memory is full). For each measured value it
is possible to set two alarm limits. The alarms are signalled by the symbols
on the LCD display, by flashing the LED, by acoustic or by sending a warning
SMS or JSON message. The data recording can be performed continuously or only
when an alarm occurs.
The dataloggers of the UxxxxM family contain a 2G (GSM) radio modem,
dataloggers of the UxxxxM family contain a combined 2G/4G (GSM and LTE) modem.
Using the modem, the device connects to the mobile operator’s network after
inserting a suitable SIM card. Modem is used to send SMS messages to up to
four selected recipients and to send the measured values using JSON messages,
e.g. to the COMET Cloud (optionally to your own storage). In addition to alarm
warning messages, SMS messages containing current measured values and alarm
statuses can be sent at regular intervals.
Device setting, data downloading and online monitoring are carried out using
the computer with the COMET Vision software installed (see
www.cometsystem.com). The USB interface is used
to communicate with the computer. The datalogger is powered by an internal Li-
Ion battery. The device includes a charging circuit, which is activated
automatically when a standard USB charger is connected or after connecting a
device to a computer. The charging takes place if the battery condition
requires it and the internal temperature of the device is in the range 0 and
40 ºC. Fast charge mode can be run by turning off the device.

INSTALLATION AND OPERATION
Insert the micro-SIM card into the device (see other side of this sheet). Use
a card with parameters conforming to the expected number of sent SMS messages
and amount of received and transmitted data. If the SIM card is protected by
PIN code, make a note it, and later insert this code into the device
configuration. Proceed with care and avoid contact of the external conductive
parts with the electronics of the device (the datalogger is constantly
supplied from the internal battery). An optional accessory is a prepaid IoT
SIM card (order code LP105) for sending data to the COMET Cloud. Please note
that this card does not support the sending of SMS messages. The UxxxxMsim and
UxxxxMsim kits with built-in IoT SIM card (e.g. U0141Msim) allows the instant
connection to the COMET Cloud.
Fasten the device on the wall with two screws or insert it into the wall
holder LP100 (optional accessory). Datalogger may be operated as a portable
one. In this kind of operation avoid the device falling down. Try to maintain
the proper working position.
- The dataloggers always install vertically (with the antenna facing up) into locations with sufficient mobile operator signal quality. Insufficient signal level can be in reinforced concrete buildings, metal chambers and other shielded areas.
- Connect the probes to the device (maximum length of cables should not exceed 30 m, recommended maximum cable length of the Pt1000 probes is 15 m). To connect Pt1000/0 probes with wire leads (U0141TM and U0141TG) use the supplied tool SP013 or a suitable screwdriver.
- The devices with all cables should be located as far as possible from potential interference sources
Set-up the device
- Connect the datalogger with attached probes to the computer. Use an USB cable with USB-C connector (max. cable length 3 m).
- Run the installed COMET Vision software and select the device you want to set up from the device list
- Click on the Configuration button. The device configuration will be downloaded and you can change the setup of individual items.
- Finally save the new configuration into the device (Apply changes)
The devices do not require special maintenance. We recommend checking the state of the battery (charge as needed) and regularly verifying the accuracy of measurements with calibration.
SAFETY INSTRUCTIONS
– Read carefully the Safety information for dataloggers with modem before
operating the device and observe it during use!
– Installation, electrical connection and commissioning should only be
performed by qualified personnel in accordance with applicable regulations and
standards
– Devices contain electronic components, it needs to liquidate them according
to currently valid conditions.
– To complement the information in this data sheet read the manuals and other
documentation, which are available in the Download section for a particular
device at www.cometsystem.com.
