Switching signal channels (SSCs) configuration The IL transducer offers two digital ouput (SSCs): • Logical, inside process data (bit0 and bit1), during IO-Link mode communication • Physical, on pin 4 and pin 2 (*) of M12 connector, during SIO mode. SSCs commute according to the overtaking (high or low) of threshold value(s) based on the main process data, that is pressure.

  • Page 28 9. FUNCTIONAL SAFETY NOTES (FOR SIL 2 / PL D CERTIFIED VERSIONS ONLY) -WAITING FOR NOTIFIED BODY CERTIFICATION- 9.1. Application The pressure sensors ILI SIL 2 / PL d perform the following safety function: The safety function performed by the sensor is the correct measurement and transduction of pressure value, read according to accuracy specification defined in the datasheet and in this user manual, to be compared with a determined safety threshold (high threshold), or de-energizing of a relay contact normally energized, at the overcoming of a set safety threshold.
  • Page 29 1) the IL transducer has analog output and is power supplied through an IO-Link master; IO-Link communication can be on or not; the transducer detects the pressure and gives in output an analog electrical value proportional to the pressure itself; SRP/CS compares the signal with its internal alarm threshold: if the threshold is exceeded the SRP/CS will stop the pressure generation systems.

  • Page 33: Relay Application Notes

    10. RELAY APPLICATION NOTES Contacts Relay manufacturers assume you will be using resistive loads when they rate their relays. The load is a simple resistive element, and it is assumed that the current flow through the contacts will be fairly constant, although some increase may occur due to arcing during “make”...

  • Page 35 Figure 11 Generally, a concave formation appears on the cathode and a convex formation appears on the anode. Contact protection circuit Use of contact protective devices or protection circuits can suppress the counter emf to a low level. However, note that incorrect use will result in an adverse effect. Typical contact protection circuits are given in the table below.
  • Page 36 In the actual circuit, it is necessary to locate the protective device (diode, resistor, capacitor, varistor, etc.) in the immediate vicinity of the load or contact. If located too far away, the effectiveness of the protective device may diminish. As a guide, the distance should be within 50cm. Switching Capacitive Loads Using relays to switch capacitive loads requires special care.

  • Page 37: Resolution Problems

    11. RESOLUTION PROBLEMS All Gefran sensors are built in conformity to UNI EN ISO 9001: 2000 In case of malfunction, you can run a series of simple checks to identify the type of fault. If the problem is caused by a sensor malfunction, the sensor MUST be returned to Gefran.

    Dependent linearity error (End point) Dependent linearity error is the deviation between the real characteristic of the transducer and the straight line passing through the two ends; expressed in % of FS. Independent linearity error (BFSL) Independent linearity error (BFSL) is the deviation between the real characteristic of the transducer and the straight line of minimum squares.
