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.

LAN data loggers can be programmed with alarm limits to warn when a
property has gone out of specification.

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.
