Operating Modes 6 Operating Modes All the ejectors in the SCPSi series can be operated in two operating modes: • Via direct connection to inputs and outputs (standard I/O = SIO) or • Connection via a communication line (IO-Link) By default, the ejector always runs in SIO mode, but it can be switched in and out of IO-Link mode by an IO-Link master at any time.
Operating Modes 6.2.1 Process Data The cyclical process data is used to control the ejectors and receive current information reported from the ejector. There is a difference between the input data (Process Data In) and the controlling output data (Process Data Out). The input data Process Data In is used to report the following information cyclically: •...
General Description of Functions 7 General Description of Functions 7.1 Picking up the Workpiece (Vacuum Generation) The ejector is designed for handling and holding workpieces by means of a vacuum in combination with suction systems. The vacuum is generated in a nozzle according to the Venturi principle, using suction generated by the flow of accelerated compressed air.
General Description of Functions • Externally time-controlled blow off The current process state is indicated by the LED status indicators. During blow off, [-FF] is shown on the display. 7.3 Operating Modes The ejector can be operated in four operating modes: •...
General Description of Functions Activating the Operating Mode Press and hold the button for more than 3 seconds. An M appears on the display while you do The current process state is retained. Manual suction button activates “suction” on the ejector. Press the button to exit the “suction”...
General Description of Functions Operating mode Explanation No control/continuous suction, H1 The ejector produces continuous suction with maximum in hysteresis mode power. This setting is recommended for very porous workpieces, which would otherwise cause vacuum gener- [ctr] => [oFF] ation to switch on and off continuously due to the high rate of leakage.
General Description of Functions Description Explanation The blow off signal overrides the suction signal, even if the specified blow off time is very long. The length of the blow off time [tbL] is set in the main menu. This menu item is suppressed in operating mode [-E-].
General Description of Functions • The pneumatic state of the ejector changes as follows: – For the NO-type ejector, the ejector switches to the “suction” operating state – For the NC-type ejector, the ejector switches to the “pneumatically OFF” operating state 7.9 Evaluating the Inlet Pressure The available supply pressure level in the system cannot be measured by the ejector itself.

General Description of Functions 7.16 Switch-off Delay You can use this function to set a switch-off delay for the H2 “Part Present” check signal. This can be used to mask short-term fluctuations in the vacuum level of the vacuum system. The duration of the switch-off delay can be set with the parameter [dlY] in the configuration menu or via IO-Link.
General Description of Functions 7.19 Resetting to Factory Settings This function restores the ejector configuration of the initial setup and the settings of the active produc- tion setup profile to the factory settings. WARNING By activating/deactivating the product, output signals lead to an action in the pro- duction process! Personal injury 4 Avoid possible danger zone.
General Description of Functions ü Select the counter you wish to see in the system menu. 4 Confirm the counter by pressing the button. ð The last three decimal places of the counter total are displayed (the digits x10 ). This corresponds to the least significant three digits.
General Description of Functions 7.23 Displaying the serial number The serial number indicates the production period of the ejector. ü In the system menu, select the 5nr parameter. 1. Confirm using the button. ð The last three decimal places of the serial number are displayed (the digits x 10 ).
General Description of Functions 7.26.1 Condition Monitoring (CM) Monitoring the valve switching frequency: 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.

General Description of Functions Evacuation times t0 and t1 Vacuum [mbar] Suction ON Time [s] If the measured evacuation time t1 (from H2 to H1) exceeds the specified value [t-1], the “Evacuation time longer than t-1” condition monitoring warning is triggered and the system status light switches to yellow. The specified value for the max.
General Description of Functions Dynamic pressure monitoring: If possible, a dynamic pressure measurement is taken at the start of every suction cycle. The result of this measurement is compared to the vacuum limit values set for H1 and H2. If the dynamic pressure is greater than (H2 - h2) but less than H1, the corresponding condition monitoring warning will be set and the system status light will switch to yellow.
General Description of Functions The measured value for the leakage rate and the related quality assessment in percent are reset at the start of every suction cycle and constantly updated during the cycle as moving averages. The values there- fore remain stable until after the suction cycle is complete. Measurement of dynamic pressure: This measures the system vacuum achieved during unobstructed suction.
General Description of Functions 7.26.6 EPC Values in the Process Data To quickly and easily capture the most important results from the condition monitoring [CM], energy monitoring and predictive maintenance functions, these are also made available via the process input data of the device. The top 3 bytes of the process output data are also configured as a multifunctional data range, consisting of an 8 bit value (“EPC Value 1”) and a 16 bit value (“EPC Value 2”).
