Safety Operation

Environmental Conditions

Ensure that the safety components are only transported, stored, and operated under the specified conditions (see technical data)!

• 
  

• Risk of injury!

  The safety components must not be used under these operating conditions:

  • Under the influence of ionizing radiation (that exceeds the level of the natural environmental radiation).
  • In corrosive environments Environment objects are global objects that exist before the execution of the script. Typically, they are global objects of Astrolab that can be accessed from the script..
  • In an environment that leads to unacceptable soiling of the safety component.

• 
  

• Electromagnetic compatibility

  The safety components comply with the current standards on electromagnetic compatibility with regard to spurious radiation and immunity to interference in particular.

  However, in cases where devices such as mobile phones, radio equipment, transmitters or high-frequency systems that exceed the interference emissions limits specified in the standards are operated near safety components, the function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. of the safety components may be impaired.

Safety Instructions

Before installing and commissioning the safety components read the Safety Instructions.

• 
  

• Commissioning Test

  Before the AKT2G-SDI-004-000/AKT2G-SDO-004-000 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.

Transport / Storage

Use the original packaging in which the components were delivered for transporting and storing the safety components.

• 
  

• Note the specified environmental conditions

  Please ensure that the digital safety components are only transported and stored under the specified environmental conditions (see technical data).

Mechanical Installation

• 
  

• Risk of injury!

  Bring the bus system into a safe, de-energized state before starting installation, disassembly or wiring of the devices!

• 
  

• Use ferrules with plastic collars

  When using fine-wire cables for signal connections, use ferrules with plastic collars. This leads to a higher system availability when test pulses When the step gets activated, the action is activated for a single execution, and possibly once again when the step is deactivated. for the corresponding channels are switched off.

Control Cabinet / Terminal Box

The safety terminals must be installed in a control cabinet or terminal box with IP54 protection class according to IEC International Electrotechnical Commission - A not-for-profit, non-governmental international standards organization that prepares and publishes International Standards for all electrical, electronic and related technologies. 60529 as a minimum.

Installation Position and Minimum Distances

For the prescribed installation position Position means a point in space which is described by different coordinates. Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation. In ACS there can be even more than six coordinates. If the same position is described in different coordinate systems the values of the coordinates are different. the mounting rail is installed horizontally and the mating surfaces of the terminals point toward the front (see illustration below). The terminals are ventilated from below, which enables Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set. Both are required for enabling the drive. optimum cooling of the electronics through convection. The direction The orientation components of a vector in space. indication “down” corresponds to the direction of positive acceleration A change in velocity over time. Because velocity is a vector, it can change in two ways: a change in magnitude and/or a change in direction. In one dimension, acceleration is the rate at which something speeds up or slows down. However, more generally, acceleration is a vector quantity expressing the change with time of the velocity both in magnitude and in direction. See these Wikipedia articles for more information: http://en.wikipedia.org/wiki/Velocity http://en.wikipedia.org/wiki/Euclidean_vector http://en.wikipedia.org/wiki/Rate_(mathematics) due to gravity.

  

Figure 1: Installation position and minimum distances

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.

• External heat sources / radiant heat / impaired convection

  The maximum permissible ambient temperature of 55°C was checked with the above example configuration.
  Impaired convection, an unfavorable location near heat sources or an unfavorable configuration of the EtherCAT Ethernet ofr Control Automation Technology. EtherCAT® is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT is to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs. Terminals may result in overheating of the terminals.

  The key parameter is always the maximum permitted internally measured temperature of 95°C, above which the safety terminals switch to safe state and report an error.
  The internal temperature can be read from the safety components via CoE.
