Redundancy
Presence of more than necessary for the function. Several functional groups are used for the same function (e.g. more channel structure). In safety engineering, especially the "duplication of...
Cleaning / Washing
In accordance with the protection class for wash-tight relays, RT III, the relays can be washed in a suitable cleaning medium. For environmental reasons, we recommend not cleaning the assemblies....
Reset button
Reset button in a SAG represents a restart interlock, which is only cancelled by actuation.
Risk assessment
Assessment of safety-related requirements, taking into account extent of damage, probability of occurrence, risk classification.
Relapse delay
When the operating voltage is applied, the timing relay immediately switches to the operating position. If the operating voltage is interrupted, the off-delay time begins. After the delay time has...
Recirculation loop
Monitors controlled actuators The SAG can only be activated when the feedback loop is closed. Safe feedback is provided, e.g. for relays or contactors, with positively driven contacts....
Closed-circuit current principle
With the closed-circuit current principle, the contact falls back into the rest position as soon as the response condition is fulfilled.
