The Pressure Control Module has three operation modes:
MEASURE
,
VENT
and
CONTROL
(see sections
2.1.2
,
2.1.3
and
2.1.4
). To select an operation mode, press one
of the buttons indicated below. The current state is indicated by the
symbol.

PCON-Y17-DT controls the pressure in the output port with high precision and
stability. To control the pressure, a pressure between 110% and 130% of the full range of
the control range is applied to the SUPPLY (+) power port, except for the 3,000 psi range
which has a reduced range of 104% to 110% of the full scale. The pressure supply must
be pneumatic, dry and clean air, nitrogen or inert gases.
If it is not possible to supply the PCON-Y17 with a pressure between 110% and
130% of the full range of the control range (and between 104% and 110% FS for the
range of 3,000 psi), a lower supply pressure may be used, but the instrument control
range will also be reduced. The PCON-Y17 measures the supply pressure and
automatically sets its control parameters for better performance. If the pressure is not
sufficient, a warning is displayed on the screen.
The presence of water, oil or particles in the pressure control module can cause
irreparable damage to the system. Equipment and connections must be clean and dry
when connected to both pressure supply and output. The use of impurities filters is
necessary to protect the system. The use of 10 micron (
m) filters is recommended.
