SentronicD
Digital Electronic Pressure Regulator
Installation Manual

CAUTION! Dangerous operating conditions may occur when using the programming interface on the valve as the valve may possibly
not react to the analog setpoint any more.
Provide for protection against uncontrolled movement of equipment when putting the valve into operation and before making any
modifications to the valve settings.

SentronicD
Installation
Manual
1. Description
SentronicDis a new generation of electronic pressure regulators designed on the basis of an enhanced digital control.
SentronicDstands for:
Digital communication and control
Display (incorporated)
Direct operated valve
Dynamic behaviour (high speed)
Digital control offers many advantages during installation and start-up of the SentronicDvalve and extended possibilities
to adapt it to various applications.
The four following standard versions are available:
• With display and pushbuttons: Pressure display, manual pressure setting and diagnostic LEDs.
• Without display and pushbuttons: The economic solution.
• Nominal diameter DN 4mm: with a flow rate of 470 l/min (SRA).
• Nominal diameter DN 8mm: with a flow rate of 1300 l/min (SRA).
Various pneumatic connections: integral connections, back panel connection and subbase mount.
• All pressure and exhaust ports are the same size, which allows for short response times when the pressure is
increased or decreased.
• Digital pressure control in a closed loop: An internal pressure sensor compares the setpoint at the inlet to the outlet
pressure. The outlet pressure is adjusted in real time.
• The control parameters can be changed with the additional software called DaS. The DaS program (Data
Acquisition Software) ensures that all parameters used by the valve can be changed. This flexibility allows the valve
to be adapted to the application and enables the optimization of its response time, overshoot and precision.
• After having set the optimum parameters you can save them in a project file for your personal use or send them to
our Product Support for future production.

After an interruption in the power supply, press both arrow buttons located beneath the display during power up to
switch to the manual mode. The operating mode is indicated by the letters “H n d” in the display.
The "H n d" display disappears when the arrow buttons are released.
Press the left arrow button or DOWN arrow to reduce the outlet pressure, press the right arrow button or UP arrow to
increase the outlet pressure. The yellow LED is on permanently during manual mode.
Exit this operating mode by pressing both arrow buttons simultaneously or by turning off the power supply for a short
time.
1.4 Operating Modes
Shut-off:
If the command signal falls below 0.5 %, the coil current is switched off and the valve is fully exhausted.
Overtemperature:
If the temperature of the internal control electronics exceeds 100°C, the operating mode is switched to AUTOSAFE
and the green LED starts to flash.
Undervoltage / overvoltage:
If the supply voltage is less than 20 V or more than 30 V, the coil current is switched off and the valve is fully exhaust-
ed. The red LED lights up constantly to indicate undervoltage or flashes to indicate overvoltage.
Autosafe:
If the coil current exceeds 1000 mA (DN8) or 560 mA (DN4) for more than 20 seconds, the output current is limited to
max. 70% every 4 seconds to prevent the valve from overheating. The yellow LED flashes.

1) The valve must only be supplied with 24V DC at a tolerance of +15%/-10% and a max. ripple of 10% (no supply via
diode bridge). Overvoltage or a ripple rate exceeding these tolerances can damage the electronics.
2) The max. current at the digital output is 200 mA/4.8W (PNP output). The output is protected against short circuit and
overload.
3) If a relay (inductive load) is connected to the digital output, a freewheel diode or a varistor must be used.
4) A shielded cable must be used for protection against interference and EMC.
5) The valve body must be grounded with the earthing terminal PE (dia. M4)

3. Analog Setpoint - Outlet Pressure
CAUTION:Outlet pressures above the maximum outlet pressure (PMR) are not controlled by the valve, i.e. the max.
outlet pressure is limited to the PMR.
In order to avoid damaging the sensor, the supply pressure must always be less than the maximum inlet pressure
defined above (see table).
The span can be set to max. 100% of the maximum outlet pressure (PMR). It can only be decreased.
Setpoint offset
The pressure setpoint zero can be changed via the DaS program. Switch to "Custom" in the "Setpoint setting" section.
The zero range is max. ±50 %.
Setpoint span
The span of the output pressure can be changed via the DaS program. Switch to "Custom" in the "Setpoint setting"
section. The span is between 10 and 100%.
