Section 3. Installation
The Rosemount 5900 2-in-1 version
The 2-in-1 version of the Rosemount 5900 has two separate level gauges
placed in the same housing. One of the tankbuses can be terminated.
The 2-in-1 version can be connected to two separate tankbuses as illustrated
in Figure 3-23 and 3-24, or to a single tankbus as illustrated in Figure 3-25 on
page 3-50.
Terminal X1 is an intrinsically safe tankbus input for level gauge 1, and
terminal X4 connects to the second level gauge.
Figure 3-23 illustrates a wiring diagram with a 2-in-1 version of the
Rosemount 5900 level gauge which is “daisy-chained” to a Rosemount 2240
multi-input temperature transmitter. Note that the Primary Tankbus is
terminated in the 5900 terminal block (X2).
