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.
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 EL2911 and EL2911-2200...
Product description EL2911 and EL2911-2200 The EL2911 is a safe potential feed terminal for the power contacts for a downstream potential group. In addition, it has 4 fail-safe inputs for sensors with potential-free contacts for 24 V The EP2911 meets the requirements of IEC 61508:2010 SIL 3 and EN ISO 13849-1:2015 (Cat 4, PL e). The safe inputs of the EL2911 meet the requirements of EN 62061:2005/A2:2015 to SILCL3, the safer output up...
. Failure to observe this can result in a loss of safety. WARNING Commissioning test Before the EL2911 can be used for the safety task, the user must carry out a commissioning test so that sensor and actuator wiring errors can be ruled out. Version: 2.0.0...

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.
CAUTION Interference-free EtherCAT Terminals In the potential group connected through the EL2911, only interference-free standard terminals must be used. A list of the interference-free EtherCAT Terminals can be found in the Beckhoff Information System under http://infosys.beckhoff.de NOTE Maximum achievable safety level for the safe output...
All conductors connected to the non-safe standard terminals are permanently installed and protected from external damage, e.g. through a cable duct or an armored conduit. CAUTION Fault exclusion The machine manufacturer or the user is solely responsible for the correct execution and evaluation of the applied alternatives. EL2911 and EL2911-2200 Version: 2.0.0...

Please ensure that the digital TwinSAFE components are only transported and stored under the specified environmental conditions (see technical data). 5.2.3 Mechanical installation WARNING Risk of injury! Bring the bus system into a safe, de-energized state before starting installation, disassembly or wiring of the devices! EL2911 and EL2911-2200 Version: 2.0.0...
• Each bus station must be terminated on the right side with the EL9011 or EL9012 end cap to ensure the protection class and ESD protection. Fig. 9: Spring contacts of Beckhoff I/O components 5.2.3.2 Control cabinet / terminal box The TwinSAFE terminals must be installed in a control cabinet or terminal box with IP54 protection class according to IEC 60529 as a minimum.
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. EL2911 and EL2911-2200 Version: 2.0.0...

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". Version: 2.0.0 EL2911 and EL2911-2200...
The following arrangement is thermally optimized, as terminals with low current consumption and therefore low waste heat are attached between the EtherCAT Coupler/power supply terminal and terminals with higher waste heat. Fig. 12: Thermally favorable arrangement of the TwinSAFE terminals EL2911 and EL2911-2200 Version: 2.0.0...

(e.g. analog Bus Terminals or digital 4-channel Bus Terminals) do not or not fully loop through the power contacts. Potential supply terminals (EL91xx, EL92xx) interrupt the power contacts and thus represent the start of a new supply rail. EL2911 and EL2911-2200 Version: 2.0.0...
The PE power contact must not be used for other potentials! 5.2.4.2 Overvoltage protection If protection against overvoltage is necessary in your plant, provide a surge filter for the voltage supply to the Bus Terminal blocks and the TwinSAFE terminals. Version: 2.0.0 EL2911 and EL2911-2200...
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. EL2911 and EL2911-2200 Version: 2.0.0...
