3.2.1 The I/O construction kit is extended safely The integrated TwinSAFE safety solution is the logical continuation of the open, PC-based Beckhoff control philosophy. Due to their modularity and versatility, the TwinSAFE components fit seamlessly into the Beckhoff control system. The I/O components are available in the formats Bus Terminal, EtherCAT Terminal, EtherCAT plug-in module and EtherCAT Box. -
Page 20: The Fail-Safe Principle (Fail Stop)
The basic rule for a safety system such as TwinSAFE is that failure of a part, a system component or the overall system must never lead to a dangerous condition. CAUTION Safe state! The safe state of the TwinSAFE system is always the switched-off and de-energized state. Version: 2.0.0 EL1918 and EL1918-2200... -
Page 21: Product Description
Fig. 4: EL1918 – TwinSAFE Terminal with 8 fail-safe inputs EL1918 variants The EL1918 has an integrated safety control that can be used for user-specific applications directly on the component. The variant EL1918-2200 does not have this functionality and represents a pure I/O component. -
Page 22: Intended Use
. Failure to observe this can result in a loss of safety. WARNING Commissioning test Before the EL1918 can be used for safety-related tasks, a commissioning test must be carried out by the user so that faulty sensor wiring can be ruled out. CAUTION Follow the machinery directive! The TwinSAFE components may only be used in machines as defined in the machinery directive. - Page 23 Note on approval according to EN 81-20, EN 81-22 and EN 81-50 • The release does not apply to the EL1918-2200, EL2911-2200 and EP1957-2222 variants. • The TwinSAFE components may only be used in machines that have been designed and installed in accordance with the requirements of the EN 60204-1 standard.

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. Version: 2.0.0 EL1918 and EL1918-2200... - Page 31 EtherCAT Coupler or the power supply terminal with high E-bus load. The additional external heating of the TwinSAFE terminals by the adjacent power supply units increases the internal terminal temperature, which can lead to the maximum permissible temperature being exceeded. This leads to the diagnosis message "Overtemperature". EL1918 and EL1918-2200 Version: 2.0.0...
