8.1.1.2
Auto Detect UF with two ULTRAFLOW® X4 on V1 and V2
The procedure for Auto Detect UF with two ULTRAFLOW® X4 is identical with the table in paragraph 8.1.1.1, with the
exception that in step ②, an identical ULTRAFLOW® X4 connected to i
nput V2 is mounted.
The ULTRAFLOW® X4 flow sensor, which is mounted on V1, will always be determining for meter factor and qp, also
in an application with two ULTRAFLOW® X4 flow sensors. This means that a replacement of ULTRAFLOW® X4 on
input V2 does not result in a config logging, but just trigger an info code. The info code will be present until
ULTRAFLOW® X4 on either input V1 or input V2 is replaced so that both ULTRAFLOW® X4 flow sensors are identical.
Replacing ULTRAFLOW® X4 by another meter factor or qp on input V1 always results in a config logging.
Note that Auto Detect UF with two ULTRAFLOW® X4 flow sensors requires that the calculator is configured for 2
ULTRAFLOW® flow sensors (Connection type 2 or 8) simultaneously with the choice of CCC = 8xx.
8.1.1.3
Information codes for Auto Detect UF
In case of incorrect ULTRAFLOW® or communication error with ULTRAFLOW® X4, MULTICAL® 803 displays a static
info code that describes the given error that has occurred (step ⑤ in t
he table in paragraph 8.1.1.1). The table
below describes the possible info codes and their importance.

Description
Remedy
Display duration of 5 s
Communication error
on input V1.
Separate the calculator and check that ULTRAFLOW® X4 is correctly
mounted in the connection terminals of input V1. Then repeat the
procedure in paragraph 8.1.1.1 from step ③.
Display duration of 5 s
Incorrect meter factor
on input V1.
The config logger is full. It is no longer possible to replace
ULTRAFLOW® X4 on input V1 by a different size than the recently
logged size for V1.
Display duration of 5 s
Communication error
on input V2.
Separate the calculator and check that ULTRAFLOW® X4 is correctly
mounted in the connection terminals of input V2. Then repeat the
procedure in paragraph 8.1.1.1 from step ③.
Display duration of 5 s
Incorrect meter factor
on input V2.
ULTRAFLOW® X4 on input V2 is different from ULTRAFLOW® X4 on
input V1. Make sure that the ULTRAFLOW® X4 flow sensors are
identical and repeat the procedure in paragraph 8.1.1.1.
Display duration of 5 s
Communication error
on both input V1 and
input V2.
Separate the calculator and check that ULTRAFLOW® X4 is correctly
mounted in the connection terminals of input V1 and input V2. Then
repeat the procedure in paragraph 8.1.1.1 from step ③.
In applications with two ULTRAFLOW® X4 flow sensors, both flow sensors must be replaced by the same type,
i.e. identical meter factor and qp.
If the meter factor and qp are not identical, an info code will be triggered.
