Power Information
This logger is a PoE (Power over Ethernet) device that is powered from its
Ethernet connection (a PoE injector is supplied).
In the event of a failure of the PoE supply, the logger has a battery back-up
that will keep it recording (communications will be suspended until power is
restored).
Back-up Battery Power
Battery Type 2 x Duracell Industrial ID1500
AA (LR6) 1.5V (supplied)
The logger will operate with other AA cell batteries but performance cannot be
guaranteed.
When the logger’s back-up batteries start to run flat, the LED on the front of
the logger will flash red. If being used as part of a Tinytag Connect system, a
low battery warning will be displayed in the Tinytag Explorer Connect software.
The low battery warnings will start to show when the logger has approximately
two weeks of battery power remaining.
Before replacing batteries the logger must be disconnected from the LAN and
turned off.
Alkaline batteries should always be replaced in pairs.
Data stored in the logger will be retained after its batteries are replaced.
Alarms
External Alarm Output
Warnings
• The alarm cable and connector must not be connected to any voltage
more than 50V away from earth potential, including mains voltages
• Maximum current through any connection: 200mA
• Maximum voltage on the Signal output (relative to Ground): 30V
The alarm output has a signal line that changes state when alarms are active
and it can also supply power to an external device.
Connection Information
An output cable (part number CAB-0041, supplied separately) is used to
connect the logger to an external device.
The wiring connections are as follows:
Both the Power (brown) and Signal (white) outputs are protected by a 350mA
self-resetting fuse.
Signal Specification
This is an open-drain output that is pulled to Ground when an alarm is active
(otherwise it is open-circuit). This output will continue to change state, in the
event of an alarm, should the PoE supply to the logger fail.
Note that muting the internal alarm sounder, by pressing the mute
button on the front of the logger, will also turn off the output. If
required, the connection should be held on (latched) by external
equipment until it is explicitly acknowledged.
Power Specification
The power output is regulated at 11·5V ±0.5V from the PoE supply. The
output voltage will therefore turn off if the PoE supply fails.
Colour Connection
Brown Power
Green Ground
White Signal
LAN data loggers can be programmed with alarm limits to warn when a
property has gone out of specification.
Alarms 2 fully programmable, latching alarms
(per channel)
Alarm Delay 1 second to 10 days
Alarm Indicators Visual (LED) & audible (sounder)
Alarm Output 3-pin, powered output that changes state
when alarms are active (see below)
Tinytag Connect
When used as part of a Tinytag Connect system, an on-screen alarm
indication is also shown in the Tinytag Explorer Connect software.
E-mail warnings can be sent from the Tinytag Connect system when alarm
limits are breached, and these in turn can be used to send SMS messages
using third-party messaging services.
Action LED Status/Operation
n/a No Indicators Device is powered off
n/a Red flash every 4
seconds
The device is powered on and
has a problem.
Either:
a) Battery is low or
b) An alarm indicator is
signalled.
Check the nature of the
problem using Tinytag
Explorer.
n/a Green flash every 4
seconds
The device is powered on, and
does not have any problems.
Press and briefly
hold the mute
switch.
Green indicator
shows for one
second. It then
briefly flashes green
then red.
The device has been switched
on.
Press and hold the
mute switch for 3
seconds.
Red indicator shows
for one second.
The device has been switched
off.
n/a Yellow indicator on
constantly
The device is being powered
from its Ethernet connection,
but no communications have
been established.
n/a Blue (flickering) Ethernet communications are
established and on-going
Ethernet Radio Recei ers and LAN data loggers ha e two status LEDs; one to
show the status of the logger’s Ethernet connection (yellow/blue) and the
second to show the status of the unit (green/red).
Note that the yellow and blue LEDs cannot be on at the same time. If the
blue LED is on (or flickering) then PoE power must be available.
