Operation
Fig. 8: Installation position and minimum distances
In order to ensure optimum convection cooling, the distances to neighboring devices and to control cabinet
walls must not be smaller than those shown in the diagram.
5.2.3.4 Temperature measurement
The temperature measurement consists of an EK1100 EtherCAT Coupler, to which EtherCAT Terminals are
attached, based on the typical distribution of digital and analog signal types at a machine. On the EL6910 a
safety project is active, which reads safe inputs and enables safe outputs during the measurement.
External heat sources / radiant heat / impaired convection
The maximum permissible ambient temperature of 55°C was checked with the example configuration
described above. Impaired convection, an unfavorable location near heat sources or an unfavorable
configuration of the EtherCAT Terminals may result in overheating of the TwinSAFE components.
The key parameter is always the maximum permitted internally measured temperature of 110°C, above
which the TwinSAFE components switch to safe state and report an error. The internal temperature can be
read from the TwinSAFE components via CoE.
