Technical Info
Introduction
The time delay relay type SD is
designed for staggered start of
two compressors in the Twinversion as the one-phase mains
cannot normally be loaded with
the total starting current of both
compressors.
When the time delay relay is used,
rst one compressor is started, and
about 10 seconds later the second
compressor is started. This ensures
the best possible characteristics
and the least load on the mains.
The time delay relay has the
following specication:
