  • Page 36: Parameters

    5.1.1 Fundamental Terms Switching functions The IMG 400 is equipped with four relays which switch in dependence of the mea- sured pressure. These relays will be referred to as «relay 1» and «relay 2». The number of relays can be increased to 7 by upgrading the device with an interface board.

  • Page 37: Configuring Switching Functions

    Pressure Normally open contact (make contact) Time Common contact Normally closed contact (break contact) The region between the threshold values generates a hysteresis (lag) between activating and deactivating of the relay. The hysteresis prevents the switching function from rapidly switching on and off when the pressure is close to one of the threshold values.
