1. Description
NC 800: For use at LABOPORT vacuum
systems.
NBC 800: Workstation vacuum control-
ler for use e. g. at vacuum supply
points.
Technical data: see chapter 8.
1.1 Unit Functions
The vacuum controller NBC 800 regula-
tes vacuum on an individual basis in
the laboratory working place. Several
different functions are possible:
Evacuation at pressure setpoint;
regulation by pressure setpoint and
pressure differential (manual ope-
ration);
defined post distillation;
experimental use;
automatic search for distillation
point (automatic operation).
1.2 Arrangement in Vacuum Systems
See fig. 1.
1.3 Mechanical Attachment
The Vacuum Controller NBC 800 can be
attached to a round support by means
of the connection on its back side
(maximum support diameter: 13 mm).
Other types of connection on request.

Manual.
1.4 Electrical Connection
Electrical supply:
The socket is located on the back
of the unit.
Cooling water valve and vacuum
valve:
Both can be connected either to
the side socket or the socket on
the back (6-pin). Proper connec-
tions are ensured by means of
different pin arrangements.
Insert plug into a properly installed
safety socket.

1.5 Pneumatic Connection
The pneumatic connection is made
at the valve block on the hose shaft
(tube ID 10mm).
