Commissioning the Logger
3.4.1
Positioning the Logger
Thanks to its IP68 protection class, the logger housing is protected against the
ingress of dust and water and, thus, especially qualified for the operation in pipeline
shafts where it can be installed next to the measuring point.
The logger can be installed in vertical and horizontal position and can also be hung
up using, e.g., a cable tie.
During field installation, the following instructions must be observed in order to
ensure proper operation of the logger:
•
Make sure that all connections to sensors of other peripheral devices are
established in a professional manner and that the connection points are
properly insulated.
•
When you plug a connection cable (VK 75, VK 76 or VK 78) in the
respective socket, make sure you feel the plug latch in. Only proper and
positive locking connections provide protection against ingress of water and
ensure error-free data transfer.
•
Care shall be taken to ensure that cables and their connections are not
subjected to tensile load.
•
Do not hang the logger on its connection cables.
•
Do not bend the connection cables.
•
Make sure the logger is switched on before you leave the site.
3.5
Positioning the GSM Antenna
If your logger is equipped with a GSM modem and if you want to make use of the
GSM functionality, you have to observe the following instructions when positioning
the GSM antenna:
•
The GSM antenna must be properly connected to the logger (see
section 3.2).
•
Be aware that thick walls and other barriers do affect the signal strength
negatively.
•
If the logger is installed underground, e.g. in a pipeline shaft, the antenna
should be positioned as near as possible to the ground surface.
Check the GSM connectivity using test functions of the SebaDataView software (see
section 5.4.7) right after the GSM antenna has been positioned. If no connection can
be established, a better position has to be found. If necessary, lead the antenna out
of the shaft and bury it a few centimetres under the ground surface.
