The safe choice – Selection of operation mode with EKS up to PL e

Tampering with safety guards is prohibited Without suitable operation mode, safety guards (e.g. safety doors) on many machines and installations still must be tampered with by bypassing for maintenance and servicing work. Providing selection of operation mode allows the operator to select the required operation mode (e.g. setup mode) and activate the suitable safety guard (e.g. enabling switch). The Electronic-Key-System EKS is ideal for convenient selection of operation mode in full compliance with laws. Requirements of laws and standards in machine building In order to use selection of...

How safe does selection of operation mode have to be? Each mode of safe operation (MSO) has one or more safety functions (SF) intended to protect the operator while working. In automatic mode, for example, a closed safety door prevents the operator from being endangered by the running machine. In “setup” mode, the operator works with the safety door open. The safety function is no longer “safety door closed” in this case, but instead the use of an enabling device in combination with reduced speed, for example. Changing the opertion mode selector switches from one safeguard to another one....

Selection of operation mode up to PL d with controls Operating panels have proven their worth over many years of practical use on machines and installations. If an additional operation mode, such as Service mode, is to be added to such machines, it is usually expedient to realize selection of operation mode with controls. Technical implementation is particularly easy in this case. The EKS with data interface or the EKS Light is used as the access system in order to restrict access to certain categories of people as required in the Machinery Directive. The controls are released with the...

The EKS System The Electronic-Key-System EKS consists of a read station and at least one Electronic-Key. The Electronic-Key contains a writable memory. Two different EKS systems are available: the EKS with data interface and the EKS Light. EKS with data interface The EKS with data interface features an Electronic-Key with freely programmable memory. With this EKS, applications such as access to control systems/operating parameters and entry of an expiration date, etc., can be realized in addition to selection of operation mode. The Electronic-Key data are transmitted from the read station to...

TIP! More safety through training Train your customers about how to perform dangerous work on the machine. Thereby give them the opportunity to operate the machine safely. If required, the training date or only general verification of training can be noted on the Electronic-Key using the EKS with data interface. With this training, you and your customers can be confident of doing everything right and meeting all legal requirements. Simply holding the Electronic-Key constitutes verification of training. Evaluation of the Performance Level (PL) of selection of operation mode Assessment of the...

Selection of operation mode with controls If controls are used for selection of operation mode, the question arises as to whether the B10d value required for determining a PL is provided by the manufacturer. This is rarely the case. However, Table D.2 in IFA Report 02/2017, which is available through the German Social Accident Insurance (DGUV), indicates that 1,000,000 cycles can be assumed as the B10d value for position switches and controls if the electrical load is < 10% of the maximum load. This will provide all of the required values, and a PL can be determined. Access system Selection...
