and outputs
Installation and operating instructions SIE...BV/DIE...BV/PBE...BV
(Terminals 41-42-43, output): SSM (collective fault signal);
potential-free changeover contact
In the event of a pump fault, the corresponding contacts as
• NC contact between terminals 41 +42 are
• NO contact between terminals 41 + 43 are
NOTE
If a DIE...BV is to be integrated into the building management system,
both pump heads must be connected separately to the SBM/SSM ter-
minals. It is not sufficient merely to connect the master.
NOTE
Terminals 1 to 22 fulfil the "safe separation" requirement (in accord-
ance with EN50178) from the mains terminals and from the SBM and
SSM terminals (and vice versa).
For SIE...BV and DIE...BV already connected at the factory, via termi-
nals 3, 7, 4, according to sensor cable designations (1), (2), (3).
NOTE
If the differential pressure sensor supplied by Salmson is replaced,
observe the colour coding of the connecting cables:
