Description of UNISAB S-Control
The UNISAB S-Control system for screw
compressors, monitors and protects the
compressor, ensuring that it operates within
the predetermined operating limits.
With UNISAB S-Control, capacity can be
regulated
manually
or
automatically
by
built-in regulators. There are also various
limiting functions.
Compressors fitted with UNISAB S-Control
or PROSAB II can be inter-connected to
form an integrated system which ensures
that the refrigeration plant operates opti-
mally.
The front panel (illustrated below) makes
the UNISAB S-Control easy to operate. The
following description refers to the position
numbers used on the drawing.
Various values have been set by SABROE
so that the UNISAB S-Control is ready to
operate when it is delivered. These values
can be changed according to the actual
operating conditions.
Note
:
UNISAB S-Control
always
remembers the
values you have set, or those set by
SABROE -- even if the power supply is cut
off.
