automatically, and its identification number (ID) is shown.
Use the
Insert
button to copy the ID shown into the directory tree.
(Alternatively: if you deactivate the “Automatic detection” checkbox, you can enter
the ID of the logger manually.)

The logger is now displayed in the directory tree. You will find it in the
group for the GT-3-1 with which it will be connected later on.

10.4 Installing all devices in the shaft
10.4.1 Installing the loggers
Install the logger/s of the GT-3-1 group in the shaft.
Detailed information on correct installation can be found in the operating manuals for the
loggers.
If you install an N-3 noise logger horizontally, make sure that the red marking on
the logger points upwards. If the marking points downwards, the logger turns off.
10.4.2 Installing the GT-3-1
Make sure that the GT-3-1 is switched on. The status LED flashes regularly.
Make sure that the GSM antenna is properly connected to the GT-3-1. Without the
antenna, the use of the GT-3-1 is not possible.
The short standard antenna for the GT-3-1 is included. It is screwed directly to the
socket of the GT-3-1.
An angle adapter is available as an optional accessory. This allows the standard
antenna to be screwed at right angles to the GT-3-1. This can be useful in a shaft with
little space.
A cable extension is available as an optional accessory. It is screwed to the GT-3-1 and
to the antenna. The extension can be useful in a deep shaft. The antenna can then be
positioned further up the shaft or even outside the shaft.
Place the GT-3-1 in the shaft. The device can be suspended or be positioned vertically
or horizontally to suit the on-site conditions. When possible, the connection sockets on
the device should point downwards.
Note: If the cable extension is used for the antenna, do not suspend the
GT-3-1 by the cable.
