Technical Information
Technical Information
Dead Band
The dead band is preset at 1.3% F.S.*, adjustable via
parameter 13. See page B17.
Accuracy
Linearity: = < 0.3% F.S.*
Proportional Band
The proportional band is preset at 10% F.S.*
Fail-safe Operation
After interrupting the
power supply voltage
, the
present output pressure is maintained at approximately
the same level. After switching the power supply on
again, the pressure can be adjusted immediately by
giving a new control signal.
Full Exhaust
Complete exhaust of the regulator is defined as
P2
≤
1% Full Scale
Degree of Protection
IP65
EU Conformity
CE: standard
EMC: according to directive 89/336/EEC
The new pressure regulator is in accordance with:
EN 61000-6-1:2001
EN 61000-6-2:2001
EN 61000-6-3:2001
EN 61000-6-4:2001
These standards ensure that this unit meets the
highest level of EMC protection.

Advanced Functionality
Pilot Valve Protection
When the required output pressure can not be achieved due
to lack of input pressure, the unit will open fully and will
display “NoP”. Approximately every 10 seconds the unit will
retry. The output pressure will then be approximately equal to
the inlet pressure. As soon as the input pressure is back on
the required level, the normal control function follows.
Safety Exhaust
Should the
control signal
fall below 0.1 volts, the valve will
automatically dump downstream system pressure.
Fail-safe
When the supply voltage drops below 19 VDC, the electronic
control reverts to the fail-safe mode. The last known output
pressure is maintained at approximately the same level,
depending upon air consumption. The digital display
indicates the last known pressure setting.
When the supply voltage is reinstated to the correct level, the
valve moves from the fail-safe mode and the output pressure
immediately follows the control signal requirement. The
display indicates the actual output pressure.
Input Protection
The unit has built-in protection against failure and burnout
resulting from incorrect input value, typically:
The 24 VDC supply is incorrectly connected to the setpoint
input, the display will show ‘OL’, as an overload indication.
The unit will need to be rewired and, when correctly
connected, will operate normally.
The overload indicator ‘OL’ will also appear should the wrong
input value be applied or the wrong input value be
programmed: (0-10 V instead of 4-20 mA or conversely
4-20 mA rather than 0-10 V). To correct this, a different set
point value should be input, or the unit reprogrammed to
correct the set point value acceptance (via parameter 4).
Response Times
To fill volume of 6.1 in
3
(100 cm
3
), connected to the outlet
of the regulator:
Pressure increase from 2 to 4 bar (30 to 60 PSI) .......30 msecs
Pressure increase from 1 to 6 bar (15 to 90 PSI) .....120 msecs
Pressure decrease from 4 to 2 bar (60 to 30 PSI) ......60 msecs
Pressure decrease from 6 to 1 bar (90 to 15 PSI) ....160 msecs
Settings
The regulator is pre-set at the factory. If required,
adjustments can be made.
