5. Transport, packaging and storage
5.1 Transport
Check the instrument for any damage that may have been caused by transport.
Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during transport (e.g. change in
installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage:
■
Storage temperature: -40 ... +85 °C
■
Humidity: 35 ... 85 % relative humidity (without condensation)
Avoid exposure to the following factors:
■
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
6. Commissioning, operation
In hazardous areas, only use field indicators that are approved for those
hazardous areas. The approval is marked on the product label.
6.1 Operating modes
The following operating modes are possible:
■
HART
®
slave / basic mode (4 ... 20 mA)
■
HART
®
master / basic mode / multidrop (models DIH52, DIH62)
6.1.1 Operating mode: HART
®
slave (models DIH50, DIH52, DIH62)
The digital indicators powered via the same current loop as the corresponding transmitters
monitor permanently the HART
®
communication. When modifying the unit or measuring
range of the connected transmitter, the unit of the digital indicator and the corresponding
indication range are adapted automatically.
However, it is required that the unit set in the transmitter is also set in the devices.
