AVENTICS R414000771 Pressure Regulator Instruction Manual

Mounting ED07 pressure regulator

The ED07 pressure regulator must always be fastened to a base plate (single subbase or base plate for stacking assembly).

Before assembly

• Make sure the relevant system part is not under voltage or pressure.

• Let the ED07 pressure regulator acclimate itself for several hours before installation, otherwise water may condense in the housing.
  NOTICE
  Risk due to incorrectly mounted device!
  An incorrectly mounted device may result in uncontrolled movements that could damage other system parts.

  • Please ensure that the device is securely fastened to a base plate, which in turn is secured to the machine or a mounting plate.

• Fasten the base plate in the control cabinet or onto a mounting plate. Vertical mounting is preferable for the ED07 pressure regulator.

  • 36 vertical axis
  • 37 horizontal axis
    The device can be mounted in any orientation if the compressed air is dry and oil-free.

• NOTICE
  Malfunction caused by closed housing ventilation port!
  If the housing ventilation port is closed, there is no atmospheric equalization and the characteristics curve will change.

  • Ensure that the air can circulate freely through the housing ventilation port (6).
  • Never operate the device in an atmosphere containing oil.

• O Before installation, ensure that the housing ventilation port (6) is open and not, for example, painted shut.

Insert gasket

1. Insert the gasket (11) on the underside of the ED07 pressure regulator so that the three pneumatic openings are not covered.
2. Apply slight pressure to the gasket so that it attaches to the three fixing pins (9).
   The three fixing pins ensure that the gasket sits correctly on the contours of the pneumatic openings.

Mounting the ED07 pressure regulator on the base plate
The base plate has a coding pin (38), which fits into the matching coding boring (8) of the ED07 pressure regulator. Correct assembly is thus ensured.

1. Rotate the ED07 pressure regulator so that the coding pin (38) and coding boring (8) are on the same side and can engage with each other.
2. Place the ED07 pressure regulator on the base plate. When you do so, make sure the gasket does not shift. The base plate coding pin fits into with the coding boring on the ED07 pressure regulator.

Some base plates have two coding pins. For this reason, there is a second coding boring on the same side of the ED07 pressure regulator. There is no risk of confusion.

Firmly screw the ED07 pressure regulator onto the base plate

1. Insert the four M5x90 screws into the four holes as shown in the figure and screw tight. Tightening torque: 6 Nm
2. Make sure again that the gasket and the housing gasket (12) sit properly in order to ensure the IP65 protection class. The gasket and housing gasket may not overlap on the side.

Connecting the supply voltage, set point, and external sensor

WARNING

Danger of injury due to the failure of the external sensor on connection X2M! The pressure regulator opens fully. The maximum permissible pressure in the system may be exceeded. Severe injuries are possible. If you use an external sensor:

• Always install safety equipment that monitors the function of the external sensor on connection X2M.

NOTICE

Missing seals and plugs will lead to non-compliance with the IP65 protection class!
Liquids and foreign objects could penetrate the device and plug connections and destroy the electronics.

• Use IP65 protection class plug-type connections.
• Make sure that the seals are integrated in the plug and not damaged.
• Make sure that all plugs are mounted before starting the system.

To operate the ED07 pressure regulator, you must supply the device with compressed air, connect the 24 V DC supply voltage, and control the device with a set point. The actual value (-) and set point (-) are always connected to 0 V. The following applies for all devices with 0…10 V voltage control: If the analog trigger signal is not electrically isolated, please heed the line resistances to minimize set point/actual value drifting and the controlled pressure. Use a shielded line to connect XPC, X2M, and X2N. The shield must be connected to the plug housing. O Please heed the following tables containing the plug assignments for the different series.

• Make sure before connecting the plugs that all seals and caps are included and not damaged.
• Only use pre-assembled and tested plugs and cables,
• Protect the supply voltage with an external M2.5A fuse.

As the 0 V lines are linked in the case of the X2M and X1S connections, as well as X2N and X1S, you must ensure that all the plug-type connections are correctly poled. Short-circuiting occurs due to pole confusion of the supply voltage or set point voltage. For devices controlled via potentiometer, integrated plug X1S and integrated socket X2M:

• Connect the lines to the X2M integrated socket as illustrated in the figure opposite. Voltage can now be supplied to the ED07 pressure regulator and the set point adjusted on the potentiometer.

Commissioning the EV07 pressure regulator

NOTICE

Risk of destruction by water!
Water entering the device destroys the electronics.

• Ensure that the compensation port is sealed.
• Ensure that the four mounting screws are tightened with the correct torque. O Never open the two fastening screws on the housing cover.

Prior to commissioning the EV07 pressure regulator

Attach base plate pneumatic connections

Depending on the application, the base plate is a single subbase or base plate for stacking assembly.

1. Connect the supply line to inlet connection°1 on the base plate (39).
2. Connect the outlet line to the output connection (unlabeled connection) on the opposite side.
3. Always connect a silencer or line for restricted exhaust to exhaust 3 (40).

CAUTION

Danger caused by escaping compressed air!
Device is operating under pressure. On opening the additional input connection (41) on the base plate, the seal screw can be hurled into the surrounding area and may cause bodily harm and material damage.

• Never undo the seal screw during operation.
• Only connect another input connection when no pressure is supplied.

Exhaust 3 (40) in the single subbase must not be sealed by a screw.

• Always mount the exhaust on an appropriate silencer (see Chapter 13 „Accessories“) or line for restricted exhaust.

Output pressure -1 bar…+1 bar:
On the ED07 pressure regulator with the pressure range -1 bar…+1 bar a vacuum must be connected to exhaust 3.

Switching on the pneumatic and electrical supplies

Proceed as follows to commission the ED07 pressure regulator:

1. First switch on the pneumatic supply.
2. Then switch on the 24 V DC supply voltage.

Setting the set point

• Enter the desired set point in the controller or potentiometer.
• Please observe Chapter „Selecting the correct supply pressure“.

Triggering the ED07 pressure regulator

You can continually adjust the pressure once you have connected the pneumatic and electrical supply on the ED07 pressure regulator. To do this, the ED07 pressure regulator is e.g. controlled via a controller or potentiometer using a set point. The electronics compares the set point with the output pressure, which is measured by a pressure sensor, and generates a control variable, which in turn triggers the venting or exhaust valve via the U/I converter and proportional solenoids. This sets the stipulated pressure.

1. Inlet connection for supply pressure
2. Outlet connection
3. Ventilation

• 42 Supply voltage
• 43 Nominal input value
• 44 Actual output value
• 45 Switch output

Selecting the correct supply pressure
A permanent deviation will occur if the supply pressure is less than the outlet pressure stipulated by the electrical set point. The electronics reduces the current consumption and thus the maximum nominal width to prevent the ED07 pressure regulator becoming hot.

CAUTION

Danger of burns caused by hot coils!
Touching the valve coils during operating may lead to burns.

• Let the device cool off before disassembling it.
• Do not touch the device during operation.
• Always select a supply pressure that is higher than the outlet pressure.

“Pressure reached” switch output

The “Pressure reached” switch output is only featured on “ED07 pressure regulators with M12 integrated plug X1S and M12 integrated socket X2M, M12”. The ED07 pressure regulator with M12 integrated plug X1S and M12 integrated socket X2M recognizes whether the required output pressure is set within a tolerance band of 2% FS.
The switch output on pin 1 of the M12 integrated socket X2M is triggered at a value equal to the supply voltage or 2.0 V lower (high level) as long as the actual value is close to the set point in the tolerance band. If the actual value is outside the tolerance band, a voltage of < 2.0 V DC (low level) is supplied to the switch output. This signal can be used to enable further process steps, for instance.

Controlling the pressure
Depending on the version, the output pressure of the ED07 pressure regulator can be controlled via the current, voltage or a potentiometer. Depending on the version, the characteristic curves in the following section depicts the linear interrelation between current and outlet pressure or voltage and outlet pressure. The device generates the supply voltage for the potentiometer in devices with an external potentiometer. The potentiometer sliding contact is connected to the set point input (see „Connecting the supply voltage, set point, and external sensor“).

1. Select the right characteristic curve according to the output pressure and device number.
2. Define the required output pressure.
3. Refer to the current or voltage characteristic curve to set the required output pressure.
4. Depending on the model, control the outlet pressure either via the controller or a potentiometer.

Characteristics
The characteristic curves for all ED07 pressure regulator versions are listed in the following.

NOTICE

Malfunction caused by closed housing ventilation port!
If the housing ventilation port is closed, there is no atmospheric equalization and the characteristics curve will change.

• Ensure that the air can circulate freely through the housing ventilation port (6).
• Never operate the device in an atmosphere containing oil.

Disassemble, replace and dispose of ED07 pressure regulator

Disassembling the EV07 pressure regulator

NOTICE

Connecting or disconnecting plugs when under voltage will damage the device!
Large differences in potential occur when connecting or disconnecting plugs under voltage, which could damage the device.

• Make sure the relevant system component is not under voltage before assembling the device or when connecting and disconnecting plugs.

CAUTION

Danger of burns caused by hot coils!
Touching the valve coils during operating may lead to burns.

• Let the device cool off before disassembling it.
• Do not touch the device during operation.

The following switch-off sequence must be observed in order to disassemble the ED07 pressure regulator.

1. Stipulate a set point of 0 bar to exhaust the ED07 pressure regulator and the outlet line on the outlet pressure connection.
2. Switch off the 24 V DC supply voltage.
3. Remove the connected plugs.
4. Switch off the supply pressure.
5. Undo the four M5x90 screws.
   The ED07 pressure regulator can now be removed.

Exchange the ED07 pressure regulator
To replace the ED07 pressure regulator, you must first disassemble it as described above and then assemble a new ED07 pressure regulator (see Chapter 6 „Mounting ED07 pressure regulator“).
