1. DESCRIPTION

The SentronicPLUS with integrated digital control loop combines the latest in pneumatics technology with intelligent electronics. The SentronicPLUS series allows precise control of pressure, flow, force, velocity and displacement or angle positions. It supplements the SentronicD series. The SentronicPLUS is available in 14 standard pressure ranges from 100 mbar to 50 bar. Four nominal sizes are provided to cover a wide flow range. Versions with different body and seal materials can be used in many sectors, e.g. the food industry, medical technology etc. Cascaded control allows setting up complex control loops using the DaS software (Data Acquisition Software). Digital control offers many advantages during installation and start-up of the SentronicPLUS valve and extended possibilities to adapt it to various applications.

• 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 measures the outlet pressure. The outlet pressure is adjusted in real time.
• The control parameters can be changed with the DaS software (from DaS release 5.00): The DaS software (Data Acquisition Software) ensures the variability of the parameters used by the valve. This flexibility allows the valve to be adapted to the most various applications, and its response time, overshoot and precision to be optimised.
• 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 serial production.
• ATEX approval for the version with M12 connector without display:

SentronicPLUS – Digital electronic pressure regulator valve

1.2 OPERATING ELEMENTS

1.3 OPERATING MODES
Shut-off:
If the setpoint 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.

Undervoltage / overvoltage:
If the supply voltage is less than 18 V or more than 30 V, the coil current is switched off and the valve is fully exhausted..

Autosafe:
If the coil current exceeds a certain value, dependent on the mechanics, for more than 20 seconds, the output current is limited to max. 70% to prevent the valve from overheating.

2. ELECTRICAL CONNECTION

1. The valve must only be supplied with 24V DC ±10% and a max. ripple of 10% (no supply via diode bridge). Over voltage 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 pressure switch 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 housing must be connected to the ground potential with low resistance via the ground connection (ØM4). The eyelet of the grounding cable must be inserted between two toothed washers and fastened with a screw (M4). The tightening torque corresponding to the screw must be observed.

CONNECTOR PINNING / CABLE WIRING

CAUTION – BE SURE TO FOLLOW THESE INSTRUCTIONS!

1. The coil must only be supplied with 24 V DC ±10 % and a max. ripple of 10 % (no supply via diode bridge). Overvoltage or a ripple rate exceeding 10 % can damage the electronics.

2. The max. current at pin 7 is 500 mA (NPN/PNP output). Pin 7 is protected against short circuit and overload.

3. If a relay (inductive load) is connected to the pressure switch output, a freewheel diode or
   a varistor must be used.

4. Do not solder unused pins on the connector.

5. In case of an interruption in the pressure supply, shut off the power supply (+24V) or switch the set point to zero to avoid excessive heating of the coil.

6. Grounding for personal protection must be done at the PE terminal (ØM4) on the body (see diagramme opposite).

7. The valve housing must be connected to the ground potential with low resistance via the
   ground connection (ØM4). The eyelet of the grounding cable must be inserted between two
   toothed washers and fastened with a screw (M4). The tightening torque corresponding to
   the screw must be observed.

3. ANALOG SETPOINT – OUTLET PRESSURE

Setpoint offset
The pressure setpoint zero can be changed via the DaS software. Switch to “Custom” in the “Setpoint setting” section. The zero range is max. -50 … +100 %.

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 (MAP) (see Table).

Setpoint span
The pressure span of the setpoint can be changed via the DaS software. Switch to “Custom” in the “Setpoint setting” section. The span is between +10 and +150 %.

The span can be set to max. 100% of the maximum outlet pressure (PMR). It can only be decreased.

4. PNEUMATIC CONNECTION

The air flow is from port 1 to port 2.

Inch screw connections (pipe threads) must be used.
Each screw connections must be lined with a fitting synthetic sealing disc.
Do not use Teflon sealing tape or hemp as they may get inside the valve and damage it.
Use an appropriate silencer at port (3). The exhaust time may vary depending on the type of silencer used.
The diameter of the pneumatic lines must be adjusted to the nominal diameter of the valve. The diameter of outlet line (2) must be larger or equal to that of inlet line (1).
The supply pressure must always be less than the value given in the table in section 3 and must always be above the desired outlet pressure.

5. TECHNICAL CHARACTERISTICS

5.1 FLUID CHARACTERISTICS

5.2 SPECIFICATIONS

(1) Residual ripple: 10 %
(2) Test conditions according to ISO 8778: temperature: 20 °C, relative inlet pressure: 6 bar, relative outlet pressure: 5 bar

INSTALLATION AND OPERATING INSTRUCTIONS

1. Before putting into operation carefully check all electrical connections and the supply voltage (24 VDC ±10 %). Overload can destroy the electronics. Recommended pre-fuse T2.0 A.

2. The electrical connection is made with a round connector M12x1. The connector must meet the requirements of DIN 60079-15. The product was tested with connector catalogue no. 88100729. In order to ensure conformity with ATEX Directive 2014/34/EU, the product must be installed in such a manner as to protect the electrical connector from mechanical stress.
   WARNING:
   Do not disconnect the connector while under voltage!

3. Use shielded cables for the electrical connection of the valve. The shield, connector and control cabinet must be EMC compliant. The valve body must be electrically connected to ground (PE, machine ground). Do not run control cables parallel to high-voltage lines, servo-motor control cables etc.

4. Min. wire cross-section of supply voltage cable: 0.50 mm2.
   For longer cabling distances use larger cross-section cables as required.

5. Make sure that the valve is under pressure when a setpoint signal is applied to the valve (applying a setpoint signal with no pressure on the valve will cause it to overheat).

6. The valve is factory adjusted.

7. The product must be returned to the factory for repair.

WARNING NOTES
These products are intended for use in industrial compressed air systems only. Do not use these products where pressures and temperatures can exceed those listed under SPECIFICATIONS. Please also see the corresponding product specification sheets.

Before using these products with fluids other than those specified, for non- industrial applications, life-support systems, or other applications not within published specifications, consult EMERSON.

Through misuse, age, or malfunction, components used in fluid power systems can fail in various modes.

The system designer is warned to consider the failure modes of all component parts used in fluid power systems and to provide adequate safeguards to prevent personal injury or damage to equipment in the event of such failure.

System designers must provide a warning to end users in the operating manual if protection against a failure mode cannot be adequately ensured.

System designers and end users are cautioned to review specific warnings found in instruction sheets packed and shipped with these products.
