PHASE 1 - PRELIMINARY CHECKS
2.2
PRESSURE AND TEMPERATURE LIMITS
The maximum allowable pressure (PS) and maximum/minimum
allowable temperature (TS) of the pressure transmitter, for
the European market are indicated on the tag plate (ref. D of
Figure 1), in the U.S. please refer to the instrument data sheets
available at: http://138.221.224.36 searching for "264 and
sheet" or from local ABB representatives.
PS and TS are defined according to the European Pressure
Equipment Directive 97/23/EC (PED). For Temperature, the
listing is for the min and max process temperature limits at
which the instrument can be exposed, for Pressure this listing
should be considered the maximum working pressure limit to
which the transmitter can be exposed without damage (to the
transmitter). These limits are valid when the transmitter is
installed according to the instructions in this manual.
WARNING ! - For potentially explosive atmosphere
applications see the temperature range specified in the
certificate/approval relevant to the intended type of
protection.

containment of the process fluid by the transmitter, it is
recommended that any part, related to process fluid
containment, be supplied only by ABB or authorized agents.

searching for "SL/26*" or from local ABB representatives.
The storage conditions must be within the following limits,
Lower limit: –50°C (–58°F); –40°C (–40°F) for LCD indicators
Upper limit: +85°C (+185°F) otherwise some material such as
gaskets may be damaged and cannot assure proper fluid
containment.
2.3
The transmitter is designed to provide a current transmission
signal of 4 to 20 mA dc on the same wires that are carrying the
power supply (two-wire transmitter).
The transmitter operates on a minimum voltage of 10.5 Vdc to
a maximum of 42 Vdc and is protected against polarity inversion.
The transmitter operates from 10.5 to 42 Vdc with no load.
The operating voltages range for fieldbus versions, both polarity
independent, are as follows:
- PROFIBUS PA from 9 to 32 Vdc (17.5 Vdc for EEx ia)
- FOUNDATION Fieldbus from 9 to 32 Vdc (for EEx ia

For EEx ia and intrinsically safe (FM, CSA and SAA) approvals,
the power supply must not exceed 30 Vdc. In some countries
the maximum power supply voltage is limited to a lower value.
The transmitter insulation resistance (terminals to earth) is
