NOTICE
Incorrect reproduction of the process pressure
If you change the factory settings of the pressure transmitter, the display and measurement output may be set so that the
true process pressure is not reproduced.
Therefore before commissioning, check the settings.
General explosion protection
WARNING
Explosion hazard for flameproof enclosure "Ex d"
Before commissioning devices with the "Flameproof enclosure" type of protection, observe the following:
The covers, safety latches and cable glands must be installed according to the instructions.
WARNING
Explosion hazard for media hotter than 100 °C flowing through the process flange
Explosion protection is no longer ensured and the approval lapses.
Media hotter than 100 °C must not flow through the process flange in operation.
Special explosion protection
WARNING
"Flameproof enclosure" type of protection
Only open devices with type of protection "Flameproof enclosure" in hazardous areas when the power to the device is
turned off, otherwise there is a risk of explosion.
WARNING
Intrinsically safe circuits
With intrinsically safe circuits, use only certified ammeters appropriate for the transmitter.
"Intrinsically safe"
If a non-conforming supply unit is used, the "fail-safe" type of protection will no longer be effective and the approval
certification will be invalid.
Instructions on commissioning
Note
To obtain stable measured values, the transmitter needs to be allowed to warm up for five minutes or so after the supply
voltage is switched on.
The operating data must correspond to the values specified on the nameplate. If you switch on the auxiliary power, the
transmitter operates.
The following commissioning cases are typical examples. Depending on the system configuration, configurations different
from those listed here may be useful.
Following commissioning, the transmitter is immediately ready for use.
The adjustable measuring span corresponds to the information on the nameplate. If the device is factory-set to user-specific
values, the start of scale value and full scale value are stated on the tag plate.
If need be, you can change the parameters by simple user operations on the device even during commissioning.
