Controller Description
The integrated controller is a solid-state frequency
converter which is driven by a single chip micro-
computer and is composed of a PCB which in-
cludes a power supply with a 3-phase AC output,
analog and input/output section, microprocessor
and digital section. The controller recognizes the
mains presence and converts the single phase AC
mains supply into a 3-phase, medium frequency
output which is required to power the pump.
The controller can be operated by a remote host
computer via the serial connection.
Diaphragm Forepump Description
The pump consists of an electric DC motor driving
an eccentric which moves an elastic diaphragm.
The pump has four heads.
The compression chamber is hermetically sepa-
rated from the drive mechanism by means of the
diaphragm.
The pump transfers, evacuates and compresses
completely oil-free.
The motor is supplied with a voltage of 24 Vdc.
NOTE
A diaphragm pump cleaning from the humidity is
recommended to improve the system performance
using dry air or nitrogen. It is recommended to
open manually the vent valve after every start
command for about 30 seconds.
