  • Page 23: Ep1918 Temperature Measurement

    EtherCAT Box. 4.2.3 EP1918 temperature measurement The temperature measurement of the TwinSAFE EtherCAT Box consists of a single EtherCAT Box that is wired with corresponding supply and communication cables. The inputs and/or outputs of the EtherCAT Box are switched on for the test.
  • Page 24: Signal Cables

    4.2.4 Signal cables Permitted cable length Fig. 12: EP1918 cable length When connecting a single switching contact via a dedicated continuous cable (or via a sheathed cable), the maximum permitted cable length is 100 m if a sensor test is active. The use of contact points, connectors or additional switching contacts in the cabling reduces the maximum propagation.
  • Page 25: Fig. 13 Cable Routing

    The common routing of signals together with other clocked signals in a common cable also reduces the maximum propagation, since crosstalk of the signals can occur over long cable lengths and cause diagnostic messages. EP1918 Version: 1.1.0...
