4.2.3.3 Example configuration for temperature measurement
Fig. 7: Example configuration for temperature measurement
The example configuration for the temperature measurement consists of an EK1100 EtherCAT coupler with
connected terminals that match the typical distribution of digital and analog signal types at a machine. On the
EL6900 a safety project is active, which reads safe inputs and enables all 4 safe outputs during the
measurement.
External heat sources / radiant heat / impaired convection
The maximum permissible ambient temperature of 55°C was checked with the above ex-
ample configuration. Impaired convection, an unfavorable location near heat sources or an
Note
unfavorable configuration of the EtherCAT Terminals may result in overheating of the termi-
nals.
The key parameter is always the maximum permitted internally measured temperature of
95°C, above which the TwinSAFE terminals switch to safe state and report an error. The in-
ternal temperature can be read from the TwinSAFE components via CoE (see chapter Di-
agnose).
