Applications for the ED02 Pressure Regulator

The ED02 pressure regulator converts an electrical set point into pressure. In doing so, a pressure sensor integrated in the ED02 pressure regulator records the outlet pressure. The integrated control electronics regulate the outlet pressure via two 2/2 directional valves. Due to this, the controlled outlet pressure remains constant if there are disturbance variables such as flow changes or supply pressure fluctuations. With the ED02 pressure regulator, you can

• Electrically change pressures,
• Remotely adjust pressures.

Additionally, you can use the ED02 pressure regulator as an actuator to control brake forces, clamping forces, flow rates, or turbine speeds.

  • Connect the outlet line at outlet connection 2 (2).
  • Connect the filter at exhaust 3 (3).

Connecting the supply voltage and set point
To operate the ED02 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. In all devices, the actual value (–) and set point (–) are always at 0 V (pin 3).

• Observe the following table containing the pin assignments of the integrated XPC plug, M12.

• Make sure before connecting the plugs that all seals and caps are included and
  not damaged.

• Only use tested plugs and cables.

• Use a shielded cable to connect the integrated XPC plug (7).
  The shield must be connected to the plug housing and the system.

  • Protect the supply voltage with an external M 0.5 A fuse.
  • Connect the cable at the integrated XPC plug.

The ED02 pressure regulator can now be supplied with voltage and controlled with a set point.

Commissioning

CAUTION
Danger of burns caused by hot proportional solenoids! Touching the proportional solenoids during operating may lead to burns.

• Observe the warning sign on the right located on the device.
• Do not touch the device during operation.
• Let the device cool off before disassembling it.

NOTICE

Defective seals or leaky connections!
Liquids and foreign objects could penetrate the device and plug connections and destroy the electronics.

• Before commissioning, make sure that all seals and plugs are leak tight.
• Never open the device.

Malfunction due to atmosphere containing oil!
Oil may clog the housing ventilation port. This will change the characteristic curve.

• Never operate the device in an atmosphere containing oil

Switching on the pneumatic and electrical supplies

NOTICE

Danger of destruction to connected devices if switched on in the wrong order!
If the valve is first connected to the electric supply and then the pneumatic supply, overshooting may cause the pressure in the working line to reach a level that is much higher than the set pressure. The pressure in the working line may even reach the level of the supply pressure before the adjusted pressure is reached.

• Make sure that the connected devices are resistant to the max. supply pressure.
• Always comply with the order for switching on the devices.

Connected devices may be destroyed due to process-related leaks!
If switched on in the proper order, the device is first connected to the pneumatic supply and then the electric supply. If the device has not yet been connected to the electric supply, contamination may cause the poppet valve to leak, causing the pressure in the working line to reach the level of the supply pressure.

• Make sure that the connected devices are resistant to the max. supply pressure.

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.

• Always select a supply pressure that is higher than the outlet pressure.

Switching on
CAUTION: Before applying compressed air to the system, check the stability of the compressed air connections and make sure that no personnel are within the hazardous zone when the compressed air supply is switched on.
Proceed as follows to commission the ED02 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.

Control

You can continually adjust the pressure once you have connected the electrical and pneumatic supply on the ED02 pressure regulator.

• To do this, the ED02 pressure regulator is e.g. controlled via a controller or potentiometer using a set point.
  • The electronics compare the set point with the outlet pressure, which is measured by an internal pressure sensor.
  • The electronics generate a control variable.
  • The control variable is used to control the air supply or exhaust valve with U/I converters and proportional solenoids.

This sets the stipulated pressure. Fig.6 shows a function block diagram for an ED02 pressure regulator with analog output.

Controlling the pressure

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 (5).
• Never operate the device in an atmosphere containing oil.

Depending on the model, the set point can be controlled by the current, voltage, or potentiometer. The device generates the supply voltage for the potentiometer in devices with an external potentiometer. The sliding contact of the potentiometer is connected with the set point input (see “Connecting the supply voltage and set point” in chapter 7).

• Depending on the model, control the outlet pressure either via the controller or a potentiometer.

The characteristic curve depicts the linear interrelation between current and outlet pressure or voltage and outlet pressure. The devices have a set point entry of 50 mbar. This means that set points with an outlet pressure of less than 50 mbar will be set to 0 bar and the outlet connection exhausted.
