  • Page 11: Components Of The Mini Compact Terminal

    3 Product Description The counting method for the ejectors starts with ejector 1 next to the bus module (shown from left to right in the figure). Correspondingly, the LED indicators apply to the limit SP2 on the bus module. The product has an IO-Link class B interface, referred to as “IO-Link” for short. The compressed air supply can be connected centrally via the bus module for all the ejectors.

  • Page 13 3 Product Description IO-Link devices have parameters which are readable or writable via the IO-Link protocol. Parameters can therefore be changed during operation via the higher level controller. Since the sensor and actuator pa- rameters are device-specific, parameter information is available for each device in the form of an IODD (IO Device Description).
  • Page 14 In addition to pure read access, the app allows you to ac- tively write the parameters of the device via NFC. The “Schmalz ControlRoom” app is available in the Google Play Store or Ap- ple App Store.

  • Page 15: Description Of The Ejector

    3 Product Description 3.5   Description of the Ejector The compact ejectors of the terminal are supplied with electrical voltage by internal transmission. The electrical connection is used for communication with the control unit of the higher-level machine. The electrical connection and compressed air supply are provided centrally for all the ejectors via the bus mod- ule.
  • Page 16 3 Product Description In the ejector variant IMP, the ejector remains in “Suction” mode if the power supply fails during auto- matic operation. This prevents objects that have been picked up from falling off the suction cup in the event of a power supply failure. This also applies when the ejector is in “venturi nozzle inactive” status with the air saving function activated.
  • Page 17 3 Product Description 3.5.1   LED Indicators on the Ejector The LEDs (1) and (2) indicate the state of the valves for each ejector. In the variant with IMP control, the LED (2) is not active. If the valve is activated, the corresponding LED lights up orange.

  • Page 37 5 Functions of the Compact Terminal and Ejectors    Measuring the Air Consumption The actual air consumption in a suction cycle is calculated taking the system pressure and nozzle size into account. The air consumption from the suction ON signal to the next suction ON signal is determined in the process.

  • Page 39 5 Functions of the Compact Terminal and Ejectors 5.11.3   Condition Monitoring [CM] Condition monitoring events that occur during the suction cycle cause the system status indicator light to immediately switch from green to yellow. The specific event that caused this switch can be seen in the Condition Monitoring parameter.
  • Page 40 5 Functions of the Compact Terminal and Ejectors    Monitoring the System Vacuum and Defining Limit Values Each ejector has an integrated sensor for measuring the vacuum. The current vacuum value can be retrieved via IO-Link. The limit values are set via IO-Link. Limit values SP1 and rP1 are used by the control function to control the vacuum.
  • Page 41 5 Functions of the Compact Terminal and Ejectors    Monitoring the Valve Switching Frequency Vacuum [mbar] Suction ON Time [s] When the air saving function is activated and there is a high leakage level in the gripping system, the ejector switches between the Suction and Suction Off states very frequently. The number of valve switch- ing procedures thus increases rapidly within a short time.
  • Page 42 5 Functions of the Compact Terminal and Ejectors The evaluation of the leakage level differentiates between two statuses: Leakage L < permitted value -L- Vacuum If the leakage L is less than the set value “Permissible leakage rate”, • the vacuum continues dropping until the reset point rP1 is reached.
  • Page 43 5 Functions of the Compact Terminal and Ejectors    Evaluate System Pressure The internal analysis functions on the ejectors sometimes require the system pressure with which the ejec- tors are operated. To make the results more precise, the actual pressure level can be communicated to the compact terminal via the process data.
