DESCRIPTION

The SentronicLP valve operates with pulsed pilot valves which change the pressure in a control chamber. A downstream flow amplifier (pressure booster) converts the control pressure into an output pressure. The output pressure is measured by a pressure sensor and fed to the integrated digital control circuit. The target value is set via the electrical plug connection as a standard signal [0 to 10 V, 0(4) to 20 mA or a 2-bit digital signal]. SentronicLP is particularly suitable for pressure control procedures where a constant pressure is required with different flow rates, such as air dosing via nozzles or turbine rotation speed control. Using the available DaS software (Data Acquisition Software), the valve can be adapted to the application if necessary.

• The pressure connections and the air vent connections are designed in the same size, which results in short response times both for increasing the pressure and for reducing the pressure.
• Digital pressure control in a closed circuit: An internal pressure sensor measures the output pressure. The output pressure is adjusted in real time.
• The control parameters can be changed with the additional DaS software. The variability of the parameters used by the valve is ensured by the DaS software. This flexibility makes it possible to adapt the valve to a very wide range of applications and to optimize the response time and the precision of the valve and prevent it from overshooting.
• After determining the optimum parameters, these can be saved for personal use in a project file, which can be sent into our Product Support Department for future series production.

1.3 MANUAL PRESSURE ADJUSTMENT (MANUAL OPERATION – ONLY FOR VERSION WITH A DISPLAY)
If the supply voltage is cut off, after a reconnection of the supply voltage and by pressing the two arrow keys below the display at the same time, the pressure regulator will change to “Manual operation” mode. This operating mode is indicated in the display by the letters “HND”. The letters “HND” in the display will disappear after the arrow keys are released. The output pressure is shown  onthe display, followed by the letters “HND” at the top right of the display. Using the arrow keys, the output pressure can be changed (left arrow key  or arrowpointing down => reduce the output  pressure, right arrowkey or arrow pointing up => increase the output pressure). This operating mode can be exited by pressing both arrow keys at the same time or by briefly cutting off the supply voltage.
1.4 OPERATING MODES
Shutoff:
If the setpoint is set to less than 0.5%, the air will be released from the valve and the current supplied to the exhaust of valve will be switched off after 10 seconds.
Over temperature:
If the internal control electronics reach a temperature above 100°C, the control function will be restricted in order to prevent any more overheating.

ELECTRICAL CONNECTION

1. The valve may only be operated with a supply voltage of 24 VDC ±10% and a maximum ripple effect of 10%. (no supply via diode bridge). Overvoltages or ripple currents exceeding these tolerance limits may result in damage to the electronics of the pressure regulator.
2. The maximum current for the pressure switch is 200 mA / 4.8 W (PNP output). The output is protected against short circuits and overloads.
3. If a relay (inductive load) is connected to the pressure switch output, a free-wheeling diode or a varistor should be used.
4. To protect against electromagnetic interference, a shielded cable must be used.
5. The valve body must be grounded using the grounding terminal (diameter M4).

WARNING / SAFETY NOTICE
The device is intended solely for operation on a power source suitable for PELV, which ensures safe electrical isolation of the operating voltage in accordance with IEC / DIN EN 60204-1. Please also pay attention to the general requirements for PELV circuits according to IEC / DIN EN 60204-1.

ANALOG TARGET VALUE – OUTPUT PRESSURE

Setpoint offset
The pressure zero point of the setpoint can be changed using the DaS software. To do this, in the section “Setpoint settings” switch to “Customer”. The maximum adjustment range for the zero point is from -50% to +100%.

WARNING: Output pressures greater than the PMR (Pressure Maximum Range) will not be regulated by the valve, i.e. the maximum output pressure is limited to the PMR.
In order to prevent damage to the sensor, the supply pressure should always be less than the maximum input pressure (MAP) (see table).
Setpoint span
The pressure range of the target value can be changed using the DaS software. To do this, in the section “Setpoint setting” switch to “Customer”. The adjustment range for the pressure is 10% to 200%.The maximum setting for the pressure range is 200% of the PMR (Pressure Maximum Range).
2-bit pressure select (only available at PSI version)
If a 2-bit Setpoint is selected, PIN2 (the analog setpoint input) will become the DIGITAL INPUT 2, and PIN4 (the digital output) will become the DIGITAL INPUT.

PNEUMATIC CONNECTION

The air flow direction is from connection 1 to 2.

1. Pressure supply at connection 1
2. Pressure output at connection 2
3. Air released at connection 3

Inch screw connections (pipe threads) are to be used.
Each screw connection must be lined with a fitting plastic sealing ring.
Teflon sealing tape and hemp may not be used, because some of these materials may end up inside the valve.
A suitable silencer is to be used at port (3). Depending on the type of silencer used, the time required for the air to be released may be extended.
The cross-section of the pneumatic lines must be adjusted to the nominal diameter of the valve. The output line (2) should have a cross-section greater than or equal to the input line (1).
The supply pressure must always be less than the value specified in the table in section 3, but it must always be greater than the desired output pressure.

ACCESSORIES

CARE AND MAINTENANCE

INSTALLATION AND OPERATING INSTRUCTIONS

1. Before putting the pressure regulator into operation, carry out a careful inspection of the electrical connections and the supply voltage (24 VDC ±10%). An overvoltage can damage the electronic systems. Recommended fuse protection T 2.0 A

2. The electrical connection is made using a circular plug connector M12x1. The connector used must comply with the requirements of German standard DIN 60079-15. The device was tested using the plug with catalog item number 88100729.
   Safety notice:
   The plug must not be pulled out when a voltage is running through it!
   When the connector plug is removed from its socket, in order to maintain the IP protection class, the protective cap supplied with the device must be fitted.

3. For the electrical connection of the valve, shielded cables must be used. The shielded connection, plug and switch cabinet must comply with EMC requirements. The valve body must be electrically grounded (protective earthing, machine grounding). Do not install control cables parallel to power cables or control cables of servomotors etc.

4. The cable cross-section area of the supply voltage cable should be at least 0.25 mm 2.
   If long supply cables are used, it may be appropriate for them to have an even larger cable cross-section area.

5. Make sure that the valve is subjected to pressure as soon as a target value signal is sent to the valve (if a target value setting is sent to the valve without the valve being under pressure, this will result in unacceptable excessive heating of the valve).

6. The device is calibrated with factory settings.

7. The device must be sent to the factory if repairs are needed.
