Electrical connections to MULTICAL®
ULTRAFLOW® 54 and MULTICAL®, galvanically coupled
If ULTRAFLOW® 54 and MULTICAL® are connected via output module (Y=1), ULTRAFLOW® is galvanically coupled with
the MULTICAL® calculator and is powered by this via the three-wire signal cable (cable length up to 10 m).
Battery life time in e.g. MULTICAL® 603 is approximately 16 years depending on communication modules in the calculator.
See
paragraph 8.6.1
for electrical data on output module (Y=1).
Note: It is not permitted to mount a supply module or battery in ULTRAFLOW® 54 with output module (Y=1).

ULTRAFLOW® 54 and MULTICAL®, galvanically separated
If ULTRAFLOW® 54 and MULTICAL® are connected via output module (Y=2 or 3) ULTRAFLOW® 54 is galvanically separated
from MULTICAL®.
See
paragraph 8.6.2
for electrical data on output module (Y=2 and 3).
Note: Flow info cannot be read.
