Manual EKS Light and Light FSA 1.4 Correct use As part of a higher-level overall system, the EKS read station is used for access control and monitoring on control systems or parts of control systems (e.g. of machines). The EKS can be used, for example, as part of an overall system for checking access rights for operating mode selection. However, it is not permitted to directly derive the operating mode from the access rights on the Electronic-Key.
Manual EKS Light and Light FSA 1.5 Obligation on the operating organization The manufacturer of and the organization operating the higher-level overall system, e.g. a machine installation, are responsible for the observance of national and international safety and accident prevention regulations applicable in the specific case.
Manual EKS Light and Light FSA 2 Safety precautions Warning! The EKS read station is not a safety component in the sense of the machinery directive. Without additional precautions the EKS read station must not be used to provide a safety function, particularly if failure or malfunction of the unit could endanger the safety or health of persons in the operating area of a machine. On this topic pay particular attention to the sections Correct use (see section 1.4) and Electrical connection (see section 7).
Manual EKS Light and Light FSA 3 Function 3.1 Functional Description 3.1.1 Functions of EKS Light EKS Light is used on control systems or parts of control systems for access control and monitoring. Instead of passwords, coded Electronic-Keys are assigned. In this way, unauthorized system access (e.g. to control and visualization systems) is prevented to the greatest possible extent. EKS Light uses a non-contact, inductive read identification system.
Manual EKS Light and Light FSA Parameter assignment for the Electronic-Keys is performed exclusively via a programming station on the PC. An EKS Electronic-Key adapter with USB interface (order No. 092 750) or with serial interface (order No. 084 750) is installed on the PC for this purpose.
Manual EKS Light and Light FSA 3.1.2 Additional functions of the version EKS FSA The EKS FSA version features an additional semiconductor switching contact (LA1/LA2) that is switched off as long as there is no authorized Electronic-Key in the Electronic-Key adapter or if the Electronic-Key cannot be read. The semiconductor switching contact is galvanically isolated from the device electronics. Either AC or DC can be switched.
